F(x) = x+ + 3<br> g(x) = 4x - 3<br> Given the functions below find (f*g)(-1)

Mashutka [201]

(f×g)(-1) is -14.

Step-by-step explanation:

Step 1: Calculate (f×g)(x) by using the formula (f×g)(x) = f(x) × g(x)

⇒ (f×g)(x) = (x + 3)(4x - 3)

⇒ (f×g)(x) = 4x² - 3x + 12x - 9

⇒ (f×g)(x) = 4x² + 9x - 9

Step 2: Find (f×g)(-1) by substituting -1 in the place of x

⇒ (f×g)(-1) = 4(-1)² + 9(-1) - 9

⇒ (f×g)(-1) = 4 - 9 - 9 =-14

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the re

mina [271]

Answer:

Step-by-step explanation:

integrate with respect to x

Area is symmetric so will be twice the integral from zero to 1

( I cannot seem to figure out how to make the lower limit negative in this editor)

$A = 2\int\limits^1_0 {(x^2 + 3) - 4x^2} \, dx$ )

$A = 2\int\limits^1_0 {-3x^2 + 3} \, dx$

$A = 6\int\limits^1_0 {-x^2 + 1} \, dx$

A = 6(-⅓x³ + x) $\left \| {{x=1} \atop {x=0}} \right.$

A = 6((-⅓(1)³ + (1)) - (-⅓(0)³ + (0)))

A = 6(⅔)

A = 4 units²

Jake ate 4/8 of a pizza. Millie ate 3/8 of the same pizza. How much of the pizza was eaten by Jake and Millie?

Len [333]

4/8 + 3/8 = 7/8
or 1/2+3/8=7/8
0.5+0.375=0.875
