Find the area of the region under the graph of f on [a, b].<br> f(x) = x2 − 8x + 17; [−1, 2]

Harman [31]

Answer:

The area is 42 area units.

Step-by-step explanation:

The area of a function f(x) on an interval [a,b] is given by:

$A = \int\limits^a_b {f(x)} \, dx$

Applying to this question:

$A = \int\limits^-1_2 {x^2 - 8x + 17} \, dx$

Then

$F(x) = \frac{x^{3}}{3} - 4x^{2} + 17x$

$A = F(2) - F(-1)$

$F(2) = frac{2^{3}}{3} - 4*2^{2} + 17*2 = \frac{8}{3} + 18 = \frac{8 + 3*18}{3} = \frac{62}[3}$

$F(-1) = frac{(-1)^{3}}{3} - 4*(-1)^{2} + 17*(-1) = -\frac{1}{3} - 21 = \frac{-1 - 21*3}{3} = -\frac{64}[3}$

$A = F(2) - F(-1) = \frac{62}[3} - (-\frac{64}[3}) = \frac{62+64}{3} = 42$

The area is 42 area units.

Jenny wants to rent a truck for one day. She contacted two companies. Laguana’s Truck Rentals charges $20 plus $2 per mile. Salv

zlopas [31]

Answer:

The total cost will be the same for both companies after 20 miles.

Step-by-step explanation:

First, I wrote the equations:

Laguna's Truck Rentals: 2x + 20

Salvatori's truck rentals: 3x

To find when the total cost for both companies will be the same, I kept substituting numbers for the variable until it worked. So, the total cost for both companies will be the same after 20 miles. Hope this helped!
