well, the shape is a trapezoid, a trapezoid has two parallel sides only, the parallel sides are called "bases", and the distance between the parallel sides is its "height".
so in the trapezoid above, it has two parallel sides, 20 m and 8 m, and the height or distance between both is 7 m, so
[tex]\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h~~=height\\ a,b=\stackrel{parallel~sides}{bases~\hfill }\\[-0.5em] \hrulefill\\ a=20\\ b=8\\ h=7 \end{cases}\implies \begin{array}{llll} A=\cfrac{7(20+8)}{2}\implies A=\cfrac{7(28)}{2} \\\\\\ A=7(14)\implies A=98~m^2 \end{array}[/tex]

A cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 9, the vertical shift is 11 units down, and the period of the function is 12π7. The graph of the function does not show a phase shift.
What is the equation of the cosine function described?
Drag a value into each box to correctly complete the equation of the function
Answers
Answer
f(x) = -9 cos((12(pi) / 7)x) -11
The base equation for a cosine graph is
f(x) = a cos(b(x-c))+d
a = amplitude
b = period
c = phase shift
d = vertical shift
if there's a reflection over the x-axis then there is a negative sign in front of the amplitude

The mean absolute deviation for the data set is 51.5.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Median represents the middle value of the given data when arranged in a particular order.
We are given that;
Mean= 59
{419,450,462,499,520,521,589,612}
Now,
Count the number of data values in the set. In this case, n = 8.
Subtract the mean from each data value and take the absolute value. For example:
∣419−509∣=90
∣450−509∣=59
∣462−509∣=47
∣499−509∣=10
∣520−509∣=11
∣521−509∣=12
∣589−509∣=80
∣612−509∣=103
Add up all the absolute differences and divide by n. For example:
MAD=890+59+47+10+11+12+80+103
MAD=412/8
MAD=51.5
Therefore, by mean the answer will be 51.5.

Write and solve an equation to find the measure of angle B.
Answers
Answer:
∠B = 40°
Step-by-step explanation:
The given angle relations can be expressed in two equations.
__
setupA + B = 90° . . . . . . . . angles are complementary
A×(1 -20%) = B . . . . . B is 20% smaller
__
solutionUsing the second equation to substitute for B in the first equation, we get ...
A + 0.80A = 90° . . . . . . substitute for B
A = 90°/1.8 = 50° . . . . . collect terms, divide by the coefficient of A
B = A(0.80) = 40° . . . . find B from A
The measure of angle B is 40°.

Determine whether the series is arithmetic or geometric. Then evaluate the finite series for the specified number of terms. 10 + 7 + 4 + . . .; n = 5
Answers
Answer:
10 + 7 + 4 + . . .; n = 5
The series is arithmetic
Common difference between terms = (-3)
10 - 3 = 7
7 - 3 = 4
Or:
10 + (-3) = 7
7 + (-3) = 4
--------------------------------------------------------------------------
Another example:
Arithmetic:
5, 9, 13, 17
common difference = 4
5 + 4 = 9
9 + 4 = 13
Geometric:
4, 8, 16, 32
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
common ratio = 2
--------------------------------------------------------------------------
10 + 7 + 4 + . . .; n = 5
a₁ = 10
a₂ = 7
a₄ = a₃ + d = 4 + (-3) = 4 - 3 = 1 (d = common difference)
a₅ = a₄ - 3 = 1 - 3 = -2
Or with formula:
[tex]d=a_{n} -a_{n-1}[/tex]
d = a₂ - a₁ = 7 - 10 = -3
aₙ = a₁ + (n - 1)d
fourth term = a₄ = 10 + (4 - 1)(-3) = 10 + 3(-3) = 10 + (-9) = 10 - 9 = 1
fifth term = a₅ = 10 + (5 - 1)(-3) = 10 + 4(-3) = 10 + (-12) = 10 - 12 = -2
Sum of the finite series (if n = 5):
[tex]S_{n} =\frac{n(a_{1} +a_{n} )}{2} \\S_{5} =\frac{5(a_{1} +a_{5} )}{2} \\S_{5} =\frac{5(10 +(-2) )}{2} \\S_{5} =\frac{5(8 )}{2} =\frac{40}{2} =20[/tex]

what Kareem has. How much do they have in their wallets?
Answers
Answer:
Christine has $18, Kareem has $23, and Trey has $92.
Step-by-step explanation:
This can be solved by using variables to represent the unkown values.
x = Christine's money
x + 5 = Kareem's money.
4(x + 5) = Trey's money.
x + (x + 5) + 4(x + 5) = 133
2x + 5 + 4x + 20 = 133
6x = 108
x = $18
This means that Christine has $18, Kareem has $23, and Trey has $92.
