Math Problem 1: What is the total area of Xavier’s lot?
Use the formula for calculating the area of a trapezoid to help answer your question:
A= a+b2c or front of lot + back of lot/2
Once Bradley has the total area of the lot, he explains to Xavier that the county only allows for 40 percent of any lot to be covered with buildings.
Math Problem 2: What is Xavier’s available lot coverage? (In other words, how big a house can he build?)
Use the formula for calculating percentage to help answer your question:
40/100 = x/Total Area.
Problem 1:
To find the area you must use the formula A = (b_1 + b_2)h/2, so you do (175 + 185)100/2 which is 360*50 = 18000cm².
A = 18000 cm²
Problem 2:
Just use the shown formula, so it would be 40/100 = x/Area, 40*18000/100 = 40*180 = 7200cm²
Available lot coverage = 7200cm²
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.
What is a trapezoid?A trapezoid is a four-sided shape that has one pair of sides parallel.
We have,
Area of a trapezoid:
= 1/2 ( a + b ) h
a and b are the two parallel sides.
h = height of the trapezium.
We have,
a = 175
b = 185
h = 100
Area of a trapezoid:
= 1/2 x ( 175 + 185 ) x 100
= 1/2 x 360 x 100
= 18000
We will calculate 40% lot coverage of the 18000 area.
40% = 40 / 100
So,
= 40/100 x 18000
= 7200
Thus,
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.

1. X/2 when x = 1/2
Putting value of x in the equation
1/2 /2 = 0.25
2. 2x2 - 8 when x = 3
2(3)2 - 8
= 2(9) - 8
= 18 - 8 = 10
3. 4(x - 7)3 + 5 when x = 9
4 (x3 - 21x2 + 147x - 343) + 5
Putting value of x
4((9)3 - 21(9)2 + 147(9) - 343) + 5
4(729 - 1701 + 1323 - 343) + 5

A local gym sells monthly memberships. The function f(x) = −x2 + 18x − 72 models the daily profit in dollars, where x is the number of memberships sold.
Determine the zeros, and explain what these values mean in the context of the problem.
x = 9, x = 18; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 9, x = 18; The zeros represent the number of monthly memberships where no profit is made.
x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 6, x = 12; The zeros represent the number of monthly memberships where no profit is made.
Answer: C.) x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit. Is not the answer
Step-by-step explanation: I took the test and got it wrong. I don't know what the answer is.
x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.
What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that a local gym sells monthly memberships. The function f(x) = −x² + 18x − 72 models the daily profit in dollars.
The given quadratic equation is solved by equating the function to zero:-
−x² + 18x − 72 = 0
x² - 18x + 72 = 0
x² - 12x -6x + 72 = 0
x ( x -12 ) -6 ( x -12 )= 0
( x - 12 ) ( x - 6 ) =0
x = 12, 6
Therefore, x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.
