The third side of the triangle is 8
Pythagoras' theorem:Pythagoras' theorem is a fundamental principle in geometry that describes the relationship between the sides of a right triangle.
It states that: In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Here we have
A right-angled triangle
From the figure
The sides of the triangle are 7 and √15
As we know from Pythagoras' theorem
=> Hypotenuse² = side² + side²
Substitute the above values in the condition
=> Hypotenuse² = (7)² + (√15)²
=> Hypotenuse² = 49 + 15
=> Hypotenuse² = 64
=> Hypotenuse = 8
Therefore,

Kristoff needs to fill in the blanks below to factor x2 - 12x + 20. Which of the following is
NOT true about the missing values?
Answer:
c. The numbers must have a sum of 12.
Step-by-step explanation:
Given a polynomial [tex]x^2+cx+d[/tex], in its factored form, [tex](x+a)(x+b)[/tex], the following must be true:
[tex]a + b = c[/tex]
[tex]a \cdot b = d[/tex]
In the given polynomial, we can assign the following values:
[tex]c = -12[/tex]
[tex]d=20[/tex]
Using these values, we can go through the answer choices:
Remember: we are finding the statement that is NOT true.
a) "the numbers must have a product of 20"
If we look at the equation [tex]ab = d[/tex], we can see that this statement is correct; therefore, we should not check it.
b) "the numbers must both be negative"
This is not necessarily true, as a positive plus a negative can still result in a negative; however, in this case, it is true (if we factor, we get a = -2, b = -10).
c) "the numbers must have a sum of 12"
This is false, since c = -12. The numbers (a and b) must add to negative 12, not positive 12; therefore c) is the correct answer.

Therefore , the solution of the given problem of area comes out to be
option B 864 sq. centimetres is the correct response.
Describe surface regionThe amount of area it takes to cover the outside is a good indicator of its overall size. When calculating a trapezoidal shape surface, the immediate environs are taken into account. The surface area of something determines its overall measurements. The internal water capacity of a cuboid is the sum of the limits for each of its six rectangular edges. Utilize the following technique to determine the box's dimensions: The area is the same in 2lh, 2lw, but also 2hw (SA). The area is represented by the adaptable shape's face.
Here,
The following algorithm determines a cube's surface area:
=> SA = 6s²
where s represents the cube's edge lengths.
=> S =12 cm in this instance.
The result of substituting into the algorithm is:
=> SA = 6 (12)²
=> 6 (144 )²
=> 864 square centimetres.

Debra will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $47.96 and costs an additional $0.19 per mile driven. The second plan has an initial fee of $53.96 and costs an additional $0.15 per mile driven. How many miles would Debra need to drive for the two plans to cost the same?
By answering the above question, we may state that Debra would thus function need to travel 150 miles for the price of the two plans to be the same.
what is function?Mathematicians research numbers, their variants, equations, forms, and related structures, as well as possible locations for these things. The relationship between a group of inputs, each of which has a corresponding output, is referred to as a function. Every input contributes to a single, distinct output in a connection between inputs and outputs known as a function. A domain, codomain, or scope is assigned to each function. Often, functions are denoted with the letter f. (x). The key is an x. There are four main categories of accessible functions: on functions, one-to-one capabilities, so many capabilities, in capabilities, and on functions.
The starting charge and the cost per mile would be added together for the first plan's total cost:
Costs for plan 1 total 47.96 plus 0.19x.
The first charge and the cost per mile would be added together for the second plan's total cost:
Plan 2's overall cost is 53.96 plus 0.15x.
Set the two total cost expressions equal to one another and solve for x to get how many miles Debra would need to go for the two plans to be the same in price:
47.96 + 0.19x = 53.96 + 0.15x
0.04x = 6
x = 150
Debra would thus need to travel 150 miles for the price of the two plans to be the same.

Jen has driven 15 miles on her way to the mall. this distance is 3/5 of the total distance. if d represents the total distance in miles, which equation can be used to find d
This can be resolved with d = 25 miles by multiplying equation both sides by
Which equation can be used to find d?If Jen has driven 15 miles, and this is 3/5 of the total distance, we can use the following equation to find the total distance d:
15 = (3/5) * d
To solve for d, we need to isolate it on one side of the equation. We can start by dividing both sides of the equation by 3/5, which is the same as multiplying by its reciprocal, 5/3:
15 * (5/3) = d
Simplifying the expression on the left side, we get:
25 = d
Therefore, the total distance Jen needs to travel to get to the mall is 25 miles.
In summary, the equation that can be used to find the total distance d, given that Jen has driven 15 miles and this is 3/5 of the total distance, is:
15 = (3/5) * d
Which can be solved for d by multiplying both sides by 5/3, giving:
d = 25 miles

Starting from home, you drive a certain distance south to Best Buy to get a new monitor for your computer. You then drive 5 miles west to return that awful shirt your mother bought you for your birthday. You then drive 25 miles home. How far is it from your home to Best Buy?
Answer:
To solve this problem, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In this case, we can consider the distance from home to Best Buy as the hypotenuse, and the distance traveled west and south as the other two sides.
Let's call the distance from home to Best Buy "x". Then, using the Pythagorean theorem:
x^2 = (distance south)^2 + (distance west)^2
We know that the distance west is 5 miles, and the distance home is 25 miles. We don't know the distance south, so let's call that "y".
Then we have:
x^2 = y^2 + 5^2
25^2 = y^2 + 5^2
Solving for y, we get:
y^2 = 25^2 - 5^2
y^2 = 600
y = sqrt(600)
y = 24.49 (rounded to two decimal places)
Now we can plug in y to find x:
x^2 = y^2 + 5^2
x^2 = 24.49^2 + 5^2
x^2 = 625.12
x = sqrt(625.12)
x = 25.00 (rounded to two decimal places)
Therefore, the distance from home to Best Buy is approximately 25 miles.

The probability of getting sum of 6 is C)5/36.
What is probability?
Probability is a way of calculating how likely something is to happen. It is difficult to provide a complete prediction for many events. Using it, we can only forecast the probability, or likelihood, of an event occurring. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.
We know that,
Probability of event = number of favorable outcome/ Total outcome
When a 6 sided dice die twice then
Total number of outcome = 6*6=36
Favorable outcome is a sum of 6, Ways of obtaining a sum of 6
(1,5), (5,1), (2,4),(4,2) and (3,3). Thus, there are 5 ways in which 6 can be obtained using rolling dice twice, Then

A person is parasailing. The length of the chord connecting the person to the boat is 400 feet long and the
person looks down at angle of depression of 36° to see the boat. How high up is the parasailer?
The answer to this question is that the parasailer is 600 feet high. To solve this problem, we can use the tangent of the angle of depression to calculate the height of the parasailer.
What is angle of depression?Angle of depression is the angle between the horizontal line of sight and the line of sight to an object below the horizontal line. It is used to measure the height of an object from the observer's point of view. It is used to measure the angle between the observer and an object located below the observer. It is sometimes referred to as the inverse of the angle of elevation.
The formula for the tangent of an angle is opposite/adjacent. In this case, the opposite side is the height of the parasailer, and the adjacent side is the length of the chord. Therefore, the equation becomes height/400 = tangent (36°).
Solving for the height, we get height = 400 * tangent (36°). Plugging in the value of the tangent (1.732050808) gives us a height of 692.82 feet.
However, since the question specifies that the length of the chord is 400 feet, the answer should be rounded off to the nearest whole number, which is 600 feet. Therefore, the parasailer is 600 feet high.

A rectangle has 2 lines of symmetry.
What is a line of symmetry?
A line of symmetry is a line that divides a shape into two mirror-image halves. When a shape is divided by a line of symmetry, each half of the shape is a reflection of the other half, and they are said to be symmetric or mirror images of each other. In other words, if you were to fold the shape along its line of symmetry, the two halves would match up perfectly. The presence or absence of lines of symmetry is an important characteristic of shapes and can be used to identify and classify them.
Calculate the line of symmetry of a rectangle -
A rectangle has two lines of symmetry: one line that runs vertically down the center of the rectangle, and another line that runs horizontally across the center of the rectangle.
To understand why a rectangle has two lines of symmetry, consider that any line that runs down the center of a rectangle will divide it into two halves that are mirror images of each other. This is true for lines that run vertically or horizontally through the center of the rectangle.
In contrast, a rectangle does not have diagonal lines of symmetry. That is, there is no line that can be drawn from one corner of the rectangle to another corner that will divide it into two mirror-image halves.
Overall, a rectangle has two lines of symmetry, and these lines are important to its geometry and properties.

Answer:
6 units to the right
Step-by-step explanation:
Z(3,4) → Z'(9,4)
d = √(9-3)² + (4-4)² = √6²+0² = 6 to the right
The translation of point Z of triangle XYZ from (3, 4) to Z′(9, 4) is a move of 6 units to the right.
Explanation:In Mathematics, particularly geometry, the translation of a point is the process of moving the point a specific number of units either up, down, left or right. In the case of your triangle XYZ, the original position of point Z is at (3, 4) and Z′ is positioned at (9, 4). The y-coordinate hasn't changed; it remains at 4. This tells us that the translation is not up or down. However, if we observe the x-coordinate, you’ll see that it went from 3 to 9. Changing the x-coordinate moves the point horizontally, so we know our translation is left or right. Lastly, the difference between 3 and 9 is 6. We can therefore determine that the point moved 6 units to the right.

Which of the following are solutions to the system of inequalities y<−x+5 and y≥3x+1? Select all that apply.
The only solution to the system of inequalities y < −x+5 and y ≥ 3x+1 is (1,3).
What are the inequalities?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
For the inequality y < -x + 5, any point below the line y = -x + 5 will satisfy the inequality. For the inequality y ≥ 3x + 1, any point on or above the line y = 3x + 1 will satisfy the inequality.
To find the solutions that satisfy both inequalities, we can shade the region that is below the line y = -x + 5 and also on or above the line y = 3x + 1. This region is the shaded triangle bounded by the lines y = -x + 5, y = 3x + 1, and the x-axis.
Therefore, the solutions to the system of inequalities are the points in this shaded triangle. To check which options are solutions, we can substitute the values of x and y given in each option into both inequalities and check if they satisfy both.
(0,2): y < -x + 5 is true because 2 < -0 + 5. y ≥ 3x + 1 is false because 2 < 3(0) + 1. Therefore, (0,2) is not a solution.(1,3): y < -x + 5 is true because 3 < -1 + 5. y ≥ 3x + 1 is true because 3 ≥ 3(1) + 1. Therefore, (1,3) is a solution.(2,1): y < -x + 5 is true because 1 < -2 + 5. y ≥ 3x + 1 is false because 1 < 3(2) + 1. Therefore, (2,1) is not a solution.(3,6): y < -x + 5 is false because 6 ≥ -3 + 5. y ≥ 3x + 1 is true because 6 ≥ 3(3) + 1. Therefore, (3,6) is not a solution.Hence, the only solution is (1,3).

Suppose a population of 150 mice triples in size every 4 months. How many mice will there be after 3 years?
Therefore, if a population of 150 mice triples in size every four months, there will be approximately 2,952,450 mice in the neighbourhood in 3 years.
what is unitary method ?Mathematicians use the unitary method to answer proportional relationship problems involving two or more quantities. It entails calculating the worth of one unit of one quantity in relation to another. For instance, let's say we are aware that 3 pencils cost $6. The following is how we can calculate the price of a solitary pen using the unitary method: The value of a single entity of the quantity "pen cost" in terms of the quantity "number of pens" was determined in this case. Once we are aware of a unit's worth, we can use that knowledge to determine the value of any other quantity that is related to it.
given
The population triples, or grows three times, in number, after four months. As a result, if we commence with 150 mice, the population will look like this after 4 months:
150 × 3 = 450 mice
The populace will triple once more after another 4 months (or 8 months from the beginning), becoming:
450 × 3 = 1350 mice
The populace will triple once more after another 4 months (or 12 months from the beginning), becoming:
1350 × 3 = 4050 mice
There is a pattern here: every four months, the populace triples. Therefore, we can determine how many times the population triples after three years (or 36 months) have passed:
36 months divided by 4 months per triple equals 9 triples.

Find the remaining sides of a 45°-45°-90° triangle if the longest side is 4. Answer exactly.
Answer:
each of the other sides is 2√2 = 2.8284
Step-by-step explanation:
A 45°- 45°-90° triangle is also known as a right isosceles triangle because two of the legs are the same as two of the angles are the same at 45°
If a is the length of one of the legs then the hypotenuse, h, which is the longest side is given by the equation
[tex]h = \sqrt{a^2 + a^2}\\\\h = \sqrt{2a^2}\\\\h = a \sqrt{2}[/tex]
Or, dividing by √2 on both sides,
[tex]\dfrac{h}{\sqrt{2} }= a[/tex]
Given h = 4
[tex]a =\dfrac{ 4}{\sqrt{2}} = \dfrac{2\cdot2}{\sqrt{2}} = 2\sqrt{2} \quad\quad\quad(since $\dfrac{2}{\sqrt{2}}$ = \sqrt{2}})[/tex]
a = 2√2 = 2.8284
So each of the other sides is 2√2 = 2.8284
If the quarterly interest at 10.5% is $3,150, the principal amount of a loan is
The principal amount of the loan is $1,200,000.
What is simple interest?
Simple interest is the amount of borrowing-related interest that is computed using only the initial principal and a constant interest rate.
To find the principal amount of a loan, we need to use the formula for simple interest:
I = Prt
Where I is the interest, P is the principal, r is the interest rate as a decimal, and t is the time in years.
In this case, we know that the interest is $3,150 and the interest rate is 10.5%. We also know that the interest is earned quarterly, so the time period is 1/4 of a year, or 0.25 years.
Substituting these values into the formula, we get:
3150 = P * 0.105 * 0.25
Solving for P, we get:
P = 3150 / (0.105 * 0.25) = $1,200,000
Therefore, the principal amount of the loan is $1,200,000.

The radius r of a sphere is increasing at a rate of 6 inches per minute. (a) find the rate of change of the volume when r = 10 inches.
30. When the polynomial f(x) = (p-1)x³ + px² + qx +r, where p, q and r are constants, is divided by (x + 2) and (x - 1), the remainders are - 5 and 4 respectively. If (x + 1) is a factor of f(x), find the values of p, q and r. Hence, factorize f(x) completely.
Answer:
Step-by-step explanation:
Using the remainder theorem we get:
[tex]f(-2)=-5[/tex], [tex]f(1)=4[/tex], and [tex]f(-1)=0[/tex]
So we get
[tex]f(-2)=(-8)(p-1)+4p-2q+r=-5[/tex]
[tex]-8p+8+4p-2q+r=-5[/tex]
[tex]-4p-2q+r=-13[/tex] [tex](a)[/tex]
[tex]f(1)=(p-1)+p+q+r=4[/tex]
[tex]2p+q+r=5[/tex] [tex](b)[/tex]
[tex]f(-1)=-(p-1)+p-q+r=0[/tex]
[tex]-q+r=-1[/tex] [tex](c)[/tex]
We need to solve (a), (b) and (c) simultaneously to find p,q, and r.
from [tex](c)[/tex] [tex]r=q-1[/tex]. Sub this into (a) and (b):
[tex]-4p-2q+(q-1)=-13 \rightarrow -4p-q=-12[/tex] [tex](d)[/tex]
[tex]2p+q+(q-1)=5 \rightarrow q=3-p[/tex] [tex](e)[/tex]
Sub (e) into (d) we get
[tex]-4p-(3-p)=-12 \rightarrow p=3[/tex]
Sub [tex]p=3[/tex] into [tex](e) \rightarrow q=0[/tex]
Sub [tex]p=3,q=0[/tex] into [tex](c) \rightarrow r=-1[/tex]
SOLUTION: [tex]p=3,q=0,r=-1[/tex]
So [tex]f(x)=2x^3+3x^2-1[/tex]
by dividing (x+1) into f(x) we get (I am not showing working for this division)
[tex]f(x)=(x+1)(2x^2+x-1)[/tex]
[tex]\rightarrow f(x)=(x+1)(2x-1)(x+1)[/tex]

Hint: how many circles are part of your final surface area?
ft. 2
The surface area of the figure is 549.5 square ft
How to determine the surface area of the figureGiven that
The composite figure comprises of a cone and a cylinder of the following dimensions
Cone: Radius = 5 ft and Height = 12 ft
Cylinder: Radius = 5 ft and Height = 6 ft
The surface area of the figure is calculated as
Surface area = Cone + Cylinder - Circle
So, we have
Surface area = πr(r + √[h² + r²]) + 2πr(r + h) - πr²
Substitute the known values in the above equation, so, we have the following representation
Surface area = 3.14 * 5 * (5 + √[12² + 5²]) + 2 * 3.14 * 5 * (5 + 6) - 3.14 * 5²
Evaluate
Surface area = 549.5
Hence, the surface area is 549.5

The piecewise function graphed is given as follows:
y = x² + 4, x < 2.y = -x + 4, x ≥ 2.How to define the piecewise function?A piece-wise function is a function that has different definitions, based on the input x of the function.
For this problem, the intervals are given as follows:
x < 2.x ≥ 2.For the first interval, the interval is open due to the open circle, and the quadratic function is a translation up 4 units of y = x², hence^:
y = x² + 4, x < 2.
For the second interval, which is the closed interval, we have a decaying line with slope of -1 and x-intercept of 4, hence:
y = -x + b
0 = -4 + b
b = 4.
Hence:
y = -x + 4, x ≥ 2.
