Answer:
h(x) = -15.6(x - 3.8)² + 241
Step-by-step explanation:
if you were to graph these equations, you can see that the second equation has a lower maximum than the rest of equations, including the original. therefore, that answer can be eliminated.
or simply recognize the equation is in vertex form and realize that 222 is the y-value of the vertex. and 222 < 230. (230 being the y-value of the parent function's vertex)
the a-value (-15.9 for the parent/original function) of the new equation must be less than the parent function's a-value. this is the rate at which the pumpkin is decreasing. the lower the value, the slower the pumpkin moves. this is an advantage, as the length it travels increases. therefore, the third and fourth options are eliminated, leaving the first option as the answer.

The areas of the squares adjacent to two sides of a right triangle are shown below
Answers
Answer:
The area of the square is 85 units^2
Step-by-step explanation:
Okay, here in this question, we are interested in calculating the area of the unknown square.
Kindly note that, since each of the other shapes are squares too, it means that the length of their sides is simply the square root of their areas.
Thus, the length of the squares are ;
√35 units and √50 units respectively
Now to find the area of the larger square, we employ the use of Pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the two other sides
Let’s call the unknown length X
x^2 = (√35)^2 + (√50)^2
x^2 = 35 + 50
x^2 = 85
x = √85 units
Now as we know that the area of a square is simply the length of the side squared,
The area of the biggest square is simply (√85)^2 = 85 units^2

Simplify $\frac{2\sqrt[3]9}{1 + \sqrt[3]3 + \sqrt[3]9}.$
Answers
Let [tex]x=\sqrt[3]{3}[/tex] and [tex]x^2=\sqrt[3]{9}[/tex]. Then
[tex]\dfrac{2\sqrt[3]{9}}{1+\sqrt[3]{3}+\sqrt[3]{9}}=\dfrac{2x^2}{1+x+x^2}[/tex]
Multiply the numerator and denominator by [tex]1-x[/tex]. The motivation for this is the rule for factoring a difference of cubes:
[tex]a^3-b^3=(a-b)(a^2+ab+b^2)[/tex]
Doing so gives
[tex]\dfrac{2x^2(1-x)}{(1+x+x^2)(1-x)}=\dfrac{2x^2(1-x)}{1-x^3}[/tex]
so that
[tex]\dfrac{2\sqrt[3]{9}}{1+\sqrt[3]{3}+\sqrt[3]{9}}=\dfrac{2\sqrt[3]{9}(1-\sqrt[3]{3})}{1-3}=\sqrt[3]{9}(\sqrt[3]{3}-1)=3-\sqrt[3]{9}[/tex]
A company is designing boxes to ship their product to stores. The design team decides that the width of the box should be five feet shorter than the length, and the height of the box should be three feet longer than the width. Due to shipping constraints, the length of the box can be no greater than six feet. The volume of the box, V(x), can be modeled by a polynomial function, where x is the length of the box. Which of the following correctly models the situation above and gives the correct domain?
Answers
Answer:
see below
Step-by-step explanation:
You can work this based only on the domain. You don't need to figure the volume, though you can if you want to check the answer further.
x represents the length of the box, which has a restriction that it can be no greater than 6 ft. This tells you x ≤ 6. However, the width is 5 ft shorter than the width, so its value is x-5. But we know the width must be greater than zero:
0 < x -5
5 < x
So, the constraints on the domain of x are ...
5 < x ≤ 6 . . . . . . only matches the last choice, (5, 6]
___
Checking the volume
The height is 3 more than the width, so the volume is ...
V = LWH = (x)(x -5)(x -5 +3) = x(x -5)(x -2) = x(x^2 -7x +10)
V = x^3 -7x^2 +10x

Step-by-step explanation:
The hypotenuse is square root 2 times as long as the sides is a true statement.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We have to find the true statement about an isosceles right triangle.
Let us use pythagoras theorem to find this
h²=a²+b²
In this case since its an isosceles right triangle, a and b most be the same.
Let's say that the measure of the sides that are equal is x and the hypotenuse is h.
Pythagoras tells us the following:
h²=x²+x²
h²=2x²
Take square root on both sides
h=√2x
Hence, the hypotenuse is square root 2 times as long as the sides

V2=u2+2as v 2 = u 2 + 2 a s Where v v is the final velocity (in m/s), u u is the initial velocity (in m/s), a a is the acceleration (in m/s²) and s s is the distance (in meters). Find v v when u u is 9 m/s, a a is 7 m/s², and s s is 28 meters.
Answers
Answer:
Final velocity, v = 21.75 m/s
Step-by-step explanation:
Given that the relation between final velocity, initial velocity, acceleration and distance traveled is expressed as:
[tex]v^2=u^2+2as[/tex]
Also, given that:
Initial velocity, u = 9 m/s
Acceleration, a = 7 m/[tex]s^2[/tex]
Distance, s = 28 m
To find:
Final velocity, v = ?
Solution:
The given relation between v, u, a and s is:
[tex]v^2=u^2+2as[/tex]
We have the values of initial velocity, acceleration and distance traveled in the question statement. We just need to put all these values to find the value of final velocity.
Let us put all the values in the given equation and try to find final velocity, v:
[tex]v^2=9^2+2\times 7 \times 28\\\Rightarrow v^2=81+14 \times 28\\\Rightarrow v^2=81+392\\\Rightarrow v^2=473\\\Rightarrow v=\sqrt{473}\\\Rightarrow v=21.75\ m/s[/tex]
So, the answer is:
final velocity, v = 21.75 m/s

You need to complete the square by adding a constant that makes the quadratic expression a perfect square of a binomial. So base your analysis on the fact that the coefficient accompanying the square term of x is one, and the fact that the middle term has coefficient 10 which is twice "5" so 5 is the likely candidate for the binomial that goes squared: (x + 5) and the square of 5 (25) is what you need to add as constant term to get the perfect square of a binomial:

Options given
A. y^2=4x^2 - 100
B. y= -x^2 + 50x - 300
C. x= -y^2 - 400

5x+4y=25 - (5x+2y=3)
Answers
Answer:
T1he values for x and y of the equations is y = 11, and x = -19/5.
Step-by-step explanation:
To solve this question, we need to rearrange the expression:
5x+4y=25 - (5x+2y=3)
Look, if we subtract one equation to the other, then:
5x+4y=25 [1]
-(5x+2y=3) [2]
Which is the same as:
5x+4y=25
-5x-2y=-3
Subtract them:
5x+4y=25
-5x-2y=-3
---------------
2y =22
y = 22/2 = 11
Then, y = 11.
To find x, we can substitute y in either equation [1] or [2].
Let us use [1]
5x+4y=25
5x+4(11)=25
5x+44=25
5x=25-44
5x=-19
x = -19/5
Then, the values for x and y of the equations is y = 11, and x = -19/5.

Answer:

Step-by-step explanation:
Complete question below:
Two positive integers are 3 units apart on a number line. Their product is 108.
Which equation can be used to solve for m, the greater integer?
m(m – 3) = 108
m(m + 3) = 108
(m + 3)(m – 3) = 108
(m – 12)(m – 9) = 108
Solution
On the number line,
Let
m= larger integer
The integers are 3 numbers apart on the number line, so
m-3=smaller integer
The product (×) of the larger and smaller integers=108
(m)*(m-3)=108
m(m-3)=108
Therefore, the equation that can be used to solve for m, the larger integer is:
m(m – 3) = 108

Solution:
Find the length of UV using the Law of Sines
[tex] \frac{t}{sin(T)} = \frac{u}{sin(U)} [/tex]
U = 22°
u = TV = 47 in
T = 180 - (125 + 22) = 33°
t = UV = ?
[tex] \frac{t}{sin(33)} = \frac{47}{sin(22)} [/tex]
Multiply both sides by sin(33)
[tex] \frac{t}{sin(33)}*sin(33) = \frac{47}{sin(22)}*sin(33) [/tex]
[tex] t = \frac{47*sin(33)}{sin(22)} [/tex]
[tex] t = 68 in [/tex] (approximated)
[tex] t = UV = 68 in [/tex]
Find the area of ∆TUV
[tex] area = \frac{1}{2}*t*u*sin(V) [/tex]
[tex] = \frac{1}{2}*68*47*sin(125) [/tex]
[tex] = \frac{68*47*sin(125)}{2} [/tex]
