grigory [225]

Answer:

0.333\pi units³

Step-by-step explanation:

Think process:

The equation is given as y = e^{-3x}

Let, y = f (x)

Therefore, f (x) = e^{-3x}

We know that the limits are y-axis and x= 3

Y-axis: x= 0

then limits are given as x= 0 and x = 3

Integrating  gives:

\int\limits^3_0 {e^{-3x} } \, dx = \frac{-1}{3}e^{-3x} + C

calculating from x= 0 to x = 3, we know volume is given by \pi \int\limits^a_b {f(x)} \, dx

= \pi[ \frac{-1}{3} e^{-9}  - (\frac{-1}{3} e^{0})]

= \pi[0.000041136 + 1/3]

= 0.333\pi units³

What is the length of AE<br><br> 1. 17.1<br> 2. 23.39<br> 3. 22.9<br> 4. 43.39
jonny [76]
I hope this helps you



17,1/17,1+20=20/20+AE


17,1/37,1=20/20+AE


171/371=20/20+AE

20+AE=20.371/171

20+AE=43,39

AE=23,39

Anita invested $6000, some at 5% and the rest at 6%. If the yearly income is $337.50, what is the amount invested at each rate?
Pepsi [2]

Let the amount invested with 5% interest be x

Therefore, the amount invested with 6% interest will be (6000-x)

It is given that the total interest earned yearly is $337.5. Thus, the equation of interest will be:

\frac{5}{100}x+\frac{6}{100}(6000-x)=337.5

Multiplying both sides by 100 we get:

5x+6(6000-x)=33750

5x+36000-6x=33750

Subtracting both sides by 36000 we get:

-x=-2250

\therefore x=2250

Thus, the amount invested at 5% is $2250

Therefore, the amount invested at 6% will be $(6000-2250)=$3750
