What is the volume of a square pyramid with a base area of 36 and a height of 9 cm?
o 36 cm
o 108 cm
o 18 cm
o 324 cm
Answer:
D (108)
Step-by-step explanation:
I did test
The volume of a square pyramid with a base area of 36 and a height of 9 cm is 108 cm. The correct option is B.
What is pyramid?A pyramid is a polyhedron with triangular faces that meet at a common vertex and a polygonal base.
The name of the pyramid is determined by the shape of the base. A pyramid with a square base, for example, is called a square pyramid; a pyramid with a triangular base, a triangular pyramid; and so on.
The formula to find the volume of a square pyramid is given by:
V = (1/3) x base area x height
Substituting the given values, we get:
V = (1/3) x 36 x 9
V = 108
Thus, the correct option is B.

Given the vertex of a parabola is (-3,1) and also contains the point (-4,-1). State the exact equation of the parabola in vertex form, show all your work.
Answer:
y = -2(x + 3)^2 - 1
Step-by-step explanation:
The vertex equation of a parabola is y = a(x - h)^2 + k. If the vertex here is (-3, 1), then this equation becomes y = a(x + 3)^2 + 1.
Knowing that the graph passes through (-4, -1), we let y = -1 and x = -4, obtaining:
-1 = a(-4 + 3)^2 - 1, which must be solved for a:
-1 = a - 1. Therefore, a = -2, and the exact equation of this parabola is:
y = -2(x + 3)^2 - 1

The number of bacteria can be represented by the equation A(t)=200(.75)^t, wherr A(t) is the amount of bacteria in grams and t is the number of days. a. Is this function growth or decay? b. What percent is the bacteria decreasing by each day? c. How many grams of bacteria will there be in 1 week? d. After how many days will there be half the initial amount of bacteria left?
Answer:
Step-by-step explanation:
a. This is a decay function, since the final value (A) gets smaller and smaller as the days pass by.
b. The bacteria is decreasing by 75% per day exponentially.
c. In order to calculate the amount of bacteria in a week we simply substitute the variable t for 7 (7 days in a week) and solve for A
A = 200(0.75)^7
A = 26.7 bacteria after 1 week
d. In order to calculate this we need to substitute the variable A with 100 and solve for t
100 = 200(0.75)^t ... divide both side by 200
0.5 = 0.75^t
[tex]\frac{ln(0.5)}{ln(0.75)}[/tex] = t
2.4 = t
It will be half the initial amount after 2.4 days.

6.5. Does Spending Measure Welfare? Suppose a community spends $1 million on salaries and equipment for its police department. Because it believes that citizens are now more law-abiding, the community decides to cut back on the number of police it employs. As a result, the community now spends $800,000 less on police officers. The crime rate remains the same.
a. What happens to measured GDP?
b. Does GDP accurately reflect welfare in this case?
Discuss the underlying issue that this example poses.
Answer:
(a) Measured GDP will decrease by $200,0000
(b) No
Step-by-step explanation:
(a) Gross Domestic Product (GDP) is the total value in monetary terms of al the goods produced in a geographic location.
There will be a $200,000 decrease in the value of the GDP of the community as a result of reduction in the community spending from $1 million to $800,000.
(b) Generally, GDP is not a true indicator of welfare, likewise in this case, GDP does not reflect the welfare of the community.
There's a decrease in the community spending from $1 million to $800,000 but there's an increase in the welfare of the community as a result of decrease in crime rate.

Dollhouse furnishing come in different sizes depending on the size of the doll house. Whyyy ratio of the size of the dollhouse item to the size of the larger item dollhouse piano: 1 3/4 in. High real piano: 3ft 6in. High
Answer:
1: 24
Step-by-step explanation:
The ratio = size of smaller object/size of larger object = Height of dollhouse piano, h/height of real piano, H
H = 3 ft 6 in = 12 in/ft × 3 ft + 6 in = 36 in + 6 in = 42 in
h = 1³/₄ in = 7/4 in
So ratio = h/H = 7/4 in ÷ 42 in = 7/4 in × 1/42 in = 1/4 × 1/6 = 1/24
So ratio = h/H = 1/24 ⇒ h:H = 1: 24

y=−x+2 y=3x−4 khan
Answer: 0
Step-by-step explanation:
2y -3x - 4 = 0
Subtract 2y from both sides of the equation.
-3x - 4 = -2y
Add 4 to both sides of the equation.
-3x = -2y + 4
Divide each term by -3 and simplify
(b) Write down the coordinates of the turning point of y = x^2 - 2x - 4
Answer: [tex](1,-5)[/tex]
Step-by-step explanation:
Given
Curve is
[tex]y=x^2-2x-4[/tex]
At the turning point of the curve, the slope will be zero.
Differentiate the curve
[tex]\Rightarrow y'=2x-2[/tex]
Substitute 0 for [tex]y'[/tex]
[tex]\Rightarrow 2x-2=0\\\Rightarrow x=1[/tex]
[tex]\therefore y=1^2-2\times 1-4=-5[/tex]
[tex](1,-5)[/tex] is the turning point
