Answer:
A = 228 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
here h = 12 and b₁ = 14, b₂ = 24 , then
A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 24) = 6 × 38 = 228 ft²

S is located at (9 -3) point T is located at (4 -3)
what is the distance from point S to point T
Answer:
5
Step-by-step explanation:
The distance formula is:
[tex]d = \sqrt {\left( {x_2 - x_1} \right)^2 + \left( {y_2 - y_1} \right)^2 }[/tex]
We can plug in the given coordinates into the equation:
[tex]d = \sqrt {\left( {4 - 9} \right)^2 + \left( {-3 - (-3)} \right)^2 }\\d = \sqrt {\left( {-5} \right)^2 + \left( {-3+3} \right)^2 }\\d = \sqrt{25 + \left( {0} \right)^2 }\\d=\sqrt{25+0}\\d=\sqrt{25}\\d=5[/tex]

7) An umpire at a little league baseball game has 14 baseballs in his pockets. Five of the baseballs are brand A, 6 are brand B, and 3 are brand C. What is the probability that the next ball he throws to the pitcher is a brand C baseball? Record your answer as a fraction, decimal, and a percent.
Answer:
3/14
Step-by-step explanation:
if he has 14 baseballs 5 of them are a so:
14-5=9
if he has 6 the are b then:
9-6=3
so 3 divided 14= 3/14
∠ and ∠ are complementary angles. If ∠ = (12x - 3)° and ∠ = (7x - 2)°, find the
∠.
Answer:
57 °
Step-by-step explanation:
Complementary angles = 90 °
Since, Your angle don't have ∠ [ ] Then Let let "C" and "y"
Thurs, C = 12x- 3 and y = 7x - 2
It is given that angles r and s are complementary angles. Two angles are complementary if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,
c + y = 90
12x - 3 + 7x - 2 = 90
19x - 5 = 90
19x = 95
x = 95/19
x = 5
Using the value of x in expression or r, we get:
c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.
So measure of angle c is 57 degrees.
Hence, the ∠ is 57 °

Consider the graph of function g.
If f(x) = x2, which equation represents function g?
A. g(x)=f(2x)
B. g(x)=f(4x)
C. g(x)=2f(x)
D. g(x)=f(1/2x)
Answer:
FOR PLATO USERS
The answer is D. g(x) = f(1/2x)
Step-by-step explanation:
A graph with f(x) = x^2 starts at point zero, just like the picture shown below, so we can only predict that the new function was stretched horizontally. The parent function, f(x) = x^2, has the following points
[tex]\left[\begin{array}{ccc}x&&y\\1&&1\\2&&4\end{array}\right][/tex]
terrible table i know (pretend its a table chart) but these are the points of a normal f(x) graph. The points of the NEW graph is:
[tex]\left[\begin{array}{ccc}x&&y\\2&&1\\4&&4\end{array}\right][/tex]
It appears that the x values in the parent function table are half of the x values in the new graph table. So, the new function would be
[tex]g(x)=f(\frac{1}{2} x)[/tex]

The functions f(x) and g(x) are described using the following equation and table: f(x) = −2(1.07)x x g(x) −4 −10 −2 −7 0 −4 2 1 Which equation best compares the y-intercepts of f(x) and g(x)? The y-intercept of f(x) is equal to the y-intercept of g(x). The y-intercept of f(x) is equal to 2 times the y-intercept of g(x). The y-intercept of g(x) is equal to 2 times the y-intercept of f(x). The y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).
The y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).
How to compare the y-intercepts?The functions are given as:
f(x) = -2(1.07)^x
Table of values for g(x)
x g(x)
−4 −10
−2 − 7
0 −4
2 1
The y-intercept is when x = 0.
So, we have:
g(0) = -4
Also, we have:
f(0) = -2(1.07)^0
f(0) = -2
-2 is greater than -4 by 2
Hence, the y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).

Anna baked 333 batches of cookies with ccc cookies in each batch. She then ate 888 cookies!
How many cookies does Anna have left?
Write your answer as an expression.
Answer:
okay so anna bakes 333 batches of whatever amount of cookies but she be bakin a ton of cookies. Like we got a whole walmart filled with anna cookies.
so we are going to make this into an expression by saying 333n-888
okay so because anna is chronically obese, she eats 888 cookies. this means we subtract 888 cookies from 333(some number) amount of cookies.
your answer?
333n - 888

Marco puts his coins into stacks. Each stack has 10 coins.
He makes 17 stacks of quarters.
He makes 11 stacks of dimes.
He makes 8 stacks of nickels.
How much money does Marco have in his stacks of coins?
Answer:
Marco has $57.50 in total.
Step-by-step explanation:
17 x 10 = 170 quarters
170 x 0.25 = $42.50
11 x 10 = 110 dimes
110 x 0.10 = $11.00
8 x 10 = 80 nickels
80 x 0.05 = $4.00
Given the functions k(x) = 2x2 − 7 and p(x) = x − 4, find (k ∘ p)(x). (k ∘ p)(x) = 2x2 − 8x 16 (k ∘ p)(x) = 2x2 − 16x 32 (k ∘ p)(x) = 2x2 − 16x 25 (k ∘ p)(x) = 2x2 − 11.
Function represents a relationship between variables. The product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
Given to us
k(x) = 2x² − 7
p(x) = x − 4
As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,
[tex](k \cdot p)(x) = k(x) \cdot p(x)[/tex]
therefore,
[tex]k(x) \cdot p(x)\\\\= (2x^2-7)(x -4)\\\\= 2x^3 - 8x^2 - 7x +28[/tex]
Hence, the product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

Answer:
56%
Step-by-step explanation:
This is percentage increase and its calculated with the formula:
C2 = x2 - x1 x 100
x1 1
where x2 = final value (75 inches)
x1 = initial value (48 inches)
c2 = relative value
pecentage increase = 100
so we say, 75 - 48 x 100
48 1
27 x 100
48 = o.5625 x 100 = 56.25%.
approximated to the nearest percent becomes 56%

Answer: 9
Step-by-step explanation: Root 18 can be broken down into root ( 9 times 2). 9 is a square root & can be taken out as its root. Root 18 equals 3 times root 2. Multiple both 12/root & 3 root 2 by root 2. Leaves 12 + 3 times 2 or 18. Now gotta take that root 2 we multiplied by back out. Break 18 into its parts, 9 times 2. Divide the 2 by root 2, gives you root 2. So 9 times root 2. Don't have to divide 9 as well, because they all the same type of operation, multiplication/division, no adding.

Answer:
The initial height is the y-intercept of the graph
slope of the graph = -2
Jordon interprets the only the slope correctly.
Aral interprets the only the initial height correctly.
Step-by-step explanation:
Slope = change in y ÷ change in x = (0 - 12) ÷ (6 - 0) = -12 ÷ 6 = -2
So the slope of the graph = -2
by inspection, the y-intercept = 12
Therefore, the equation for the line is y = -2x + 12
Jordon interprets the only the slope correctly.
Aral interprets the only the initial height correctly
