The equation for the volume of a pyramid is (l*w*h)/3
 
 since the problem gave you the base area, that would be the l *w

so now you would need to multiply the base area by the height, then divide by 3

16 * 15 = 240

240/ = 80 cubic centimeters

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units,
zepelin [54]
K is the distance of the vertical translation.
Since you shifted the graph 7 units down, k will be equal to 7
So g(x) = (0.5)x - 7 is f(x) vertically translated 7 units down

If g(x) is obtained by shifting f(x) down by 7 units
meaning that
g(x)=(0.5)~~~~~7 units to the bottom from f(x)-k?

I can't explain but k=-7

it's g(x)=f(x)-(-7)
so the k=7.

f(x)-k=f(g)-7
the original function of f(x) is obtained by shifting f(g) 7 units down, or by -7
so x=7

What is the multiplicative rate of change of the exponential function represented in the table
stepan [7]
We are given the following data
x    y
1     4.5
2     6.75
3      10.125
4      15.1875

To get the multiplicative rate of change, we pick out two pairs of data so,
MROC = 6.75/4.5 / (2 - 1)
MROC = 1.5

The answer is 1.5

Which set of side lengths will form a right triangle?
Vlad1618 [11]
The set of side lengths that form a right triangle is 7, 24, 25


Explanation:
We can solve this using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, a^2 + b^2 = c^2. We can plug each set of numbers into the equation, one by one, to see if the set of numbers is true in the equation. One thing to note is that the largest number out of the set is always the hypotenuse, or c. The other numbers are the legs (a and b.)

5, 11, 13

a^2 + b^2 = c^2
(5)^2 + (11)^2 = (13)^2
25 + 121 = 169
146 ≠ 169

Since 146 doesn't equal 169, this is NOT a right triangle


9, 24, 25

a^2 + b^2 = c^2
(9)^2 + (24)^2 = (25)^2
81 + 576 = 625
657 ≠ 625

Since 657 doesn't equal 625, this is NOT a right triangle


7, 24, 25

a^2 + b^2 = c^2
(7)^2 + (24)^2 = (25)^2
49 + 576 = 625
625 = 625

This equation is true, because 625 = 625. Therefore this IS a right triangle.

The population of a city in Texas is about 1,030,000. The population of the city in t years can be predicted using the equation
Nitella [24]

Answer:

  2,856,271

Step-by-step explanation:

We presume your equation is intended to be ...

  P = 1,030,000(1.12)^t

To find the prediction in 9 years, put 9 where t is and do the arithmetic.

  P = 1030000(1.12^9) ≈ 2,856,271

In 9 years, the population is predicted to be about 2,856,271.

Ali and Janet are selling gifts at a local craft show. For every bar of soap that Ali sells, she earns $5. For every mug that Ja
Alexus [3.1K]

Answer:

95$

Step-by-step explanation:

Alli sells 5 bars, for each bar she earnd 5$ so she earns 5*5=25$

Janet sells 7 mugs, and for every mug she earns 10$ (twice then Alli), so she earns 7*10=70$

Together: 25+70=95$
