The cost of a pizza varies directly as the square of its radius. If a
pizza with a 6 inch radius costs $8.00, how much should a pizza with
an 11 inch radius cost?
The cost of a pizza with an 11 inch radius is $26.86
In this question, the cost of a pizza varies directly as the square of its radius.
Let C be the cost of pizza and r be the radius of Pizza.
We have been given the direct proportionality between the cost of pizza and the radius of Pizza.
C ∝ r²
If a pizza with a 6 inch radius costs $8.00
8 = k * 6^2
where k is the proportionality constant.
8 = k * 36
k = 0.222
We need to find the cost of pizza with an 11 inch radius.
so, we get an equation,
C = k * 11^2
substitute above value of k
C = 0.222 * 11^2
C = 0.222 * 121
C = $26.86
Therefore, the cost of a pizza with an 11 inch radius is $26.86

y≥x²+2x-8 factor the quadratic equation to find x intercepts
The factors of the quadratic equation are x≥-4, x≥2 and lies in the interval (-∞, -4]∪[2, ∞)
What is meant by quadratic equation?A quadratic equation is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown value and a, b, and c represent known numbers. In general, a = 0; equations with a = 0 are considered degenerate because the equation becomes linear or even simpler. The numbers a, b, and c are the equation's coefficients, and they can be distinguished by referring to them as the quadratic coefficient, linear coefficient, and constant or free term, respectively.
To find x-intercept y=0
y≥x²+2x-8
x²+2x-8≥0
x²+4x-2x-8≥0
x(x+4)-2(x+4)≥0

Answer:
X= 29 because it is a right angle, and all right angles are = to 90, so you subtract 61 from 90.Y= 29Z= 61
Step-by-step explanation:
Answer:
Step-by-step explanation:
Summation of all angles within a triangle is equal to 180 degrees.
y+61+90=180
Therefore, y = 180-61-90 = 29 degrees
61+x = 90
Therefore, x = 90-61 = 29 degrees
z+90+29 = 180
Therefore, z = 180 - 90 - 29 = 61 degrees

What is the Equation of the Graph of an Absolute Value Function?The equation, in vertex form, of a absolute value function is expressed as y = a|x – h| + k, where:
(h, k) = vertex of the graph a = this value determines if the graph opens up or opens down.h = horizontal translation factork = vertical translation factorFrom the graph, we know that:
Vertex (h, k) = (3, 5)
Substitute h = 3 and k = 5 into the equation, y = a|x – h| + k:
y = a|x - 3| + 5
A point on the graph is (5, 7). To find the value of a, substitute x = 5 and y = 7 into the equation y = a|x - 3| + 5:
7 = a|5 - 3| + 5
7 = 2a + 5
7 - 5 = 2a + 5 - 5 [subtraction property of equality]

The slope of the line that passes through the given pair of points is, -3/7.
What is slope of the line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. where "m" represents a line's slope. So, the slope of a line is tanθ.
Given: (8, -2), (1, 1)
Since, if two points [tex](x_1, y_1), (x_2, y_2)[/tex] are given then slope (m) is defined as,
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex].
Here,
[tex](x_1, y_1) = (8, -2)\\(x_2, y_2)=(1, 1)[/tex]
So, the slope can be defined as,
[tex]m = \frac{1-(-2)}{1-8} \\m=\frac{3}{-7} \\m=-\frac{3}{7}[/tex]

8. If a population doubles every 5 years, how many years will it take for the population to increase by 10 times
its original amount?
First: If the population gets multiplied by 2 every 5 years, what does it get multiplied by each year? Use this
to help you answer the question.
After ≈16.61 years the population will increased by times it's original amount.
What do you mean by population?
A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people from which a statistical sample is taken in statistics.
Given: If a population doubles every 5 years.
Assume, 'A' is the starting population, and 't' is the passing time in years.
Given the fact that a population doubles every five years, our population is growing exponentially, as per the question.
Here, the equation can be written as follows: [tex]A(t) = A(2)^{\frac{t}{5} }[/tex] (1)
We now need to determine when the population will have multiplied by 10 by that time.
Let's substitute [tex]A(t) = 10A[/tex] in the above equation.
[tex]10A = A(2)^{\frac{t}{5} }[/tex]
[tex]10 = (2)^{\frac{t}{5} }[/tex]
Taking the natural log of both sides we get:
[tex]ln10 = \frac{t}{5} \times ln2[/tex] {[tex]ln(a)^n= nln(a)[/tex]}
2.3025 x 5 = t x 0.6931
[tex]t = \frac{2.3025}{0.6931}\\t = 16.6096[/tex]

how many 44-digit positive integers (that is, integers between 10001000 and 99999999, inclusive) having only even digits are divisible by 55?how many 44-digit positive integers (that is, integers between 10001000 and 99999999, inclusive) having only even digits are divisible by 55?
There are 100 4-digit positive integers are possible between 1000 and 9999.
Our first step is to divide the four digit number into four places: tens, hundreds, and thousands.
To solve this problem, we must start from the right-hand side and find how many even numbers should be placed where the desired answer can be obtained.
There are a total of [0, 2, 4, 6, and 8] objects
There should only be one digit on one place, since it is the only digit that makes the number divisible by five
There are 1 ways to fill the one's place, so the total number is 1.
It is possible to take any number from the given sets of even numbers in the tens place,
There are five ways to fill one place, so there are five ways to fill it.
Taking a look at the hundreds place,
All numbers can be placed in the hundreds place from the given sets, so all numbers can be taken from the hundreds place.
Therefore, there are five ways to fill the hundreds place.
Taking a look at the thousands,
It is possible to fill thousands of places with 4 numbers from a given set of even numbers.
Therefore, there are four ways to fill the thousands place
The next step is to use the concept of factorial to find the number of ways to make a 4-digit number from even numbers that are divisible by 5.
To fill the respective places, we will multiply all the ways we calculated
= 4 × 5 × 5 × 1
= 100
Hence, there 100 4-digit positive integers possible.

Find the value of x and 3x
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
now let's consider the white, "cut-out" triangle on the left side.
the purple one angles at the top and bottom corner are 45°.
the withe outer angles at the same corners (they are the inner angles for the white triangle) are complementary angles (together they have 90°) to the purple ones, because due to the equal angles at the top and bottom we know the connection between the 2 45° angles (the white baseline) is at a 90° angle to the 45° to 135° sides.
so the 2 baseline angles of the left white triangle are also 45° (45+45 = 90).
and that means that the third white angle is
180 - 45 - 45 = 90°.
and because a full circle around the 3x° point must have 360° (as any full circle), we know that both angles (90° and 3x°) together are 360°.
360 = 90 + 3x
270 = 3x
x = 90°
3x = 270°

Part A: How tall is the pole? Show your work.
Part B: How far from the base of the pole does Wire 2 attach to the ground? Show your work.

A. Applying the trigonometric ratio, the length of pole = 29.6 ft.
B. 23.1 ft.
C. Length of wire 1 = 45.1 feet.
How to Apply the Trigonometric Ratios?The trigonometric ratios are:
sin ∅ = opposite length/hypotenuse length cos ∅ = adjacent length/hypotenuse lengthtan ∅ = opposite length/adjacent length.Part A: Apply the trigonometric ratio, tan ∅ = opp/adj, to find the length of the pole
∅ = 41°
Opp. = length of pole
Adj. = 34 ft
Substitute
tan 41 = length of pole/34
Length of pole = (tan 41)(34) = 29.6 ft.
Part B:
Let the distance between the base of the pole and wire 2 be represented as x. Therefore, apply tan ∅ = opp/adj.
∅ = 38
Opp. = x
Adj. = 29.6 ft
Therefore:
tan 38 = x/29.6
x = (tan 38)(29.6)
x = 23.1 ft.
Part C: Use the Pythagorean theorem to find the length of wire 1.
Length of wire 1 = √34² + 29.6²)

The last four digits of the number nn are 4944
Given that,
Let nn stand for the lowest positive integer that can be represented in base-1010 using only the numbers 44 and 99, with at least one of each. This number must be divisible by both 44 and 9,9.
The last two digits of n must be divisible by 4 for n to be divisible by 4.
So last digits of n will be 44.
And for divisiblity by 9, sum of all digits of n has to be divisible by 9.
As two digits are fixed and their total is 8, next feasible total will be 45 so 9 can be atleast one time in n.
And as statement says n has to be smallest number n will be 4444444944
