Answer:
150 square feet
Step-by-step explanation:
Method 1: The area of a trapezoid is
A = (8 + 17) / 2 x 12 = 150 square feet
Method 2: You can also split it into a rectangle and a triangle.
12 x 8 + 12 x (17 - 8)/2 = 150 square feet
Find the equation of a circle whose center is at (-3, 7) and radius is 9 units.
Answer:
(x + 3)² + (y - 7)² = 81
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius
here (h, k ) = (- 3, 7 ) and r = 9 , then
(x - (- 3) )² + (y - 7)² = 9² , that is
(x + 3)² + (y - 7)² = 81
Answer:
[tex]x^2+y^2+6x-14y-23=0[/tex]
Step-by-step explanation:
[tex](x-(-3))^2+(y-7)^2=9^2\\x^2+6x+9+y^2-14y+49=81\\x^2+y^2+6x-14y-23=0[/tex]

A gym membership with two personal training sessions costs $125, while gym membership with five personal training sessions costs $260. What is cost per session?
Answer:
Cost of per session the average rate is $45.
Step-by-step explanation:
It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.
It is required to find what is the cost per session.
Step 1 of 1
It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.
To find the cost of per session calculate the average rate.
Now let $f(x)$ be the cost per session use the for the average rate of change, and the input value is the number of personal traings x.
[tex]$m=\frac{f\left(x_{2}\right)-f\left(x_{1}\right)}{x_{2}-x_{1}}$$[/tex]
Now substitute, $125 for [tex]$f\left(x_{2}\right)[/tex], 260 for [tex]$f\left(x_{1}\right), 2$[/tex] for [tex]$x_{1}$[/tex] and 5 for [tex]$x_{2}$[/tex] then,
[tex]$m=\frac{260-125}{5-2}$\$$\begin{aligned}&=\frac{135}{3} \\&=45\end{aligned}$$[/tex]

The minimun point on the graph of the equation y=f(x) is -1,-3. What is the minimum point on the graphof the equation y=f(x-5)
The minimum point on the graph of the equation y=f(x-5) is (-6, -3)
How to determine the minimum?The initial minimum is given as:
(-1, -3)
The transformation y = f(x - 5) means that:
(x, y) = (x - 5, y)
So, we have:
(x, y) = (-1 - 5, -3)
Evaluate
(x, y) = (-6, -3)
Hence, the minimum point on the graph of the equation y=f(x-5) is (-6, -3)

if an equilaterl triangle is inscribed in a circle of a radius 8cm.then what is the area of the triangle?
The area of the triangle is 83.14 square centimeters.
How to get the area of the triangle?If an equilateral triangle is inscribed in a circle of radius R, each side of the triangle measures:
S = R*√3
In this case R = 8cm.
And we know that the area of an equilateral triangle of side length S is:
[tex]A = \frac{\sqrt{3} }{4} *S^2[/tex]
Replacing what we know in the area formula:

Last summer, Richard's garden measured 45 feet in length and 18 feet in width.
This summer, Richard decides to resize his garden by decreasing the length of the garden, and increasing the width of the garden by two times the length reduction.
The area of this year's garden, A(x), can be modeled by a quadratic function, where x is the number of feet that the length is reduced.
Length = (45 – x)
Width = (18 + 2x)
Then the maximum potential area of this year's resized garden will be
A(x) = (45 – x)(18 + 2x)
A(x) = 810 + 72x – 2x²
A(x) = 2(405 + 36x – x²)
For maximum potential, A'(x) = 0
A'(x) = 0
36 - 2x = 0
2x = 36
x = 18
Then the maximum potential area will be
A(x) = 2(405 + 36 × 18 – 18²)

Answer:
A. 36
Step-by-step explanation:
Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other
if the area of a triangle is hb/2,
(with h=length of height, b=length of base)
the height of the first triangle is:
25 = 10h/2
50 = 10h
h=5
you can write ratios representing the proportions of the two triangles:
5/x = 10/12 (with x=height of second triangle)
x=6
then find the area of the second triangle with the height (6) and base (12)
(6*12)/2 = 36

Answer:
Part A) B
Part B) D
Step-by-step explanation:
Given:Total sweets = 10
Red = 4
Green = 2
Yellow = 3
Purple = 1
A = 2/10 = 1/5
B = 3/10
C = 4/10 = 2/5
D = 1
Solution:Part A)Yellow sweets = 3
Total = 10
Probability = yellow/total
Probability = 3/10Hence, B shows the probability of showing a yellow sweet.
Part B)Sweets that are not orange = 10 (All sweets are not orange)
Total = 10
Probability = sweets that are not orange / total
Probability = 10 / 10
Probability = 1Hence, D shows the probability of choosing a sweet that is not orange.

Describe a relationship modeled by the function [tex]f(x) = 4x^3 - 72x^2 + 320x[/tex], and explain how the function models the relationship.
Then, identify and interpret the key features of the function in the context of the situation described in part A.
(Describe a relationship that could be modeled by the given function. There is no single correct answer: any scenario that fits the function type is correct.)
The relationship modeled that has the function of f(x) = 4x³ - 72x² + 320x is known to be the volume of a right prism that has its dimensions to be : 4 times of its desired length, 10 units lower that its desired length, and 8 units lower than its desired length.
What is the volume of the prism about?For us to know the relationship modeled by the above function, the best way to do it is for one to factor it.
The function is: f(x) = 4x³ - 72x² + 320x
First. we factor it so as to extract the common factor 4x:
Secondly, we factor the quadratic trinomial.
This is often done by writing it as a product of two binomials where the two constant terms are said to be sum up - 18 and its product is said to be 80.
The above terms are known to be -10 and - 8; so the two factors are said to be (x - 10) and (x - 8).
Therefore The relationship modeled that has the function of f(x) = 4x³ - 72x² + 320x is known to be the volume of a right prism that has its dimensions to be : 4 times of its desired length, 10 units lower that its desired length, and 8 units lower than its desired length.
Where it has :
x = the desired length,
4x = 4 times its desired length,
x - 10 = 10 lower than its desired length,
x - 8 = 8 lower than its desired length,
We can therefore say that the volume of the prism is said to be the product of the three factors which are:
V = (4x)(x-10)(x-8)
