Mrrafil [7]

Answer:

Below.

Step-by-step explanation:

3x + 5y = 15

Subtract 3x from both sides:

5y = -3x + 15

Divide through by 5:

A region is bounded by y=e−3x, the x-axis, the y-axis and the line x = 3. If the region is the base of a solid such that each cr
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

If g(x) = 7(x2 + 3) - 10 what is the value of g(5)?<br> a. 186<br> b. 206<br> c. 46<br> d. 20
stira [4]

Answer:

a) 186

Step-by-step explanation:

g(x) = 7(x^2 + 3) - 10

g(5) = 7((5)^2 + 3) - 10

g(5) = 7(25 + 3) - 10

g(5) = 7 × 25 + 7 × 3 - 10

g(5) = 175 + 21 - 10

g(5) = 186
