First find the volume of the patio by multiplying the three dimensions since it's rectangular. (25)(20)(1.5) = 750

Then take the amount per cubic foot 4.99 and multiply it by the volume 750 to get

$3742.50

True or false?is the point(16,4) included in this function: Y=2x or Y=x2 or y= x+12 or y=x-12
Gelneren [198K]

Answer:

True

Step-by-step explanation:

It is true because the graph of y=x-12 passes through the point (16,4)

x = 16

y = 4

Substitute

4 = 16 - 12

4 = 4

Therefore, the answer is true.

Which function could be a stretch of the exponential decay function shown on the graph?
dezoksy [38]

Answer:

f(x) = (\frac {1}{2})^{(6x)}

Step-by-step explanation:

The given options are,

a) f(x) = 2^{(6x)}

b) f(x) = (\frac {1}{2})^{(6x)}

c) f(x) = 2 \times (\frac {1}{6})^{x}

d) f(x) = \frac {1}{2} \times (\frac {1}{6})^{x}

Now, clearly a) is a monotonically increasing function, hence discarded, and both of c)  and d) don't pass through (0, 1) hence they are also discarded.

Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.

How many ounces are in 2 1/4 pounds?
Verdich [7]

Answer:

36 ounces

Step-by-step explanation:

1 lb = 16oz

So just multiply 2 lb by 16 to get 32.

Then you can multiply 16 by 0.25 (a.k.a 1/4) OR divide 16 by 4

You get 4 ounces

Finally, add 32 and 4 to get your total of 36 ounces.
