The volume, in cubic feet, of a right cylindrical silo of height h and radius r is V = πr2h. The height of the silo is h(r) = 3.

5r. Which statements are true regarding the functions described? Check all that apply. To get a volume of 100 cubic feet, the radius must be 2 feet. The domain of V(h(r)) is restricted to values of r greater than 0. The output of V is the input of h. V(h(r)) = 3.5πr3 The volume depends on the radius of the cylinder.

Marta_Voda [28]

Answer:

Option C. $6,012

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to

V=P(1-r)^{t}

where  

V is the the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal

t is Number of Time Periods  

in this problem we have  

t = 7 years

P = $8,000

r = 0.04

substitute in the formula above

V = 8,000(1-0.04)^{7} = 6,012

Hope this helps :)

Anika [276]
The most likely answer is D) <span>"The date that the check is written is usually a few days before it is cashed. We record when it was cashed and you record when its written". 

There is usually a delay between when you write someone a check (and record it in your ledger) and when that person cashes it (when the bank records it). </span>

If a and b are two integers then closure property states then​
Margarita [4]

Your question has been heard loud and clear.

If a and b are two integers , then closure property states that the product of the two integers a and b , which is ab , is also an integer.

Thank you

Compute the integral (a) int sin (pi x) dx by letting u = pi x. (b) int e^(x/2) dx by letting u = x/2. Show that you got the cor
Maslowich

Answer:

(a) \int sin(\pi x) dx=-\frac {cos \pi x}{\pi}+c

(b)\int e^\frac{x}{2} dx =2e^\frac{x}{2}+c

Step-by-step explanation:

(a)

\int sin(\pi x) dx

Let u = π x

differentiating with respect to x

du = π dx

\Rightarrow dx=\frac{du}{\pi}

Putting the value of x and dx

=\int sin u \frac{du}{\pi}

=\frac{-cos u}{\pi}+c    [ c is an arbitrary constant]

Now putting the value of u

=-\frac {cos \pi x}{\pi}+c  

(b)

\int e^\frac{x}{2} dx

Let u=\frac{x}{2}

differentiating with respect to x

du= \frac{1}{2} dx

2du = dx

Putting the value of x and dx

=\int e^u.2.du

=2e^u +c

Now putting the value of u

=2e^\frac{x}{2}+c       [ c is an arbitrary constant]

Charlene and Gary want to make trail mix. In order to get the right balance of ingredients for their tastes they bought 3 pounds
AfilCa [17]

Answer:

$2.96

Step-by-step explanation:

3x$2.67=$8.01

3x$2.73=$8.19

5x$3.27=$16.35

$8.01+$8.19+$16.35=$32.55

This makes 11 pounds of trail mix.

$32.55 divided by 11 = $2.9590909 = $2.96
