Answer:

Step-by-step explanation:

To find the inverse of a function, first replace f(x) with y.

Next, switch all the x's and y's, and then solve for y.

Finally, replace y with f-1(x).

What is an equation for the line perpendicular to y = 3x – 1 that passes through (-9, -2)?

FinnZ [79.3K]

Answer:

y = -1/3x - 5

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, so the line is:

y = -1/3x + b

Finding the value of b, using the given point (-9, -2)

-2 = -1/3*(-9) + b
-2 = 3 + b
b = -2 - 3
b = -5

The line is

y = -1/3x - 5

Select all the pairs that could be reasonable approximations for the diameter and circumference of a cirlce 5 meters and 22 mete

bazaltina [42]

Answer:

Option a) circle 5 meters and 22 meters

Step-by-step explanation:

We are given the following information in the question:

A pair of diameter and the circumference is given. We have to find a correct approximations for the diameter and circumference.

a) circle 5 meters and 22 meters

$\text{Diameter} = 5\text{ meters}\\\text{Circumference} = \pi d = 3.14\times 5 = 15.7\text{ meters}$

b) 19 inches and 50 inches

$\text{Diameter} = 19\text{ inches}\\\text{Circumference} = \pi d = 3.14\times 19 = 59.66\text{ inches}$

c) 33 centimeters and 80 centimeters

$\text{Diameter} = 33\text{ centimeters}\\\text{Circumference} = \pi d = 3.14\times 33 =103.62\text{ centimeters}$

Thus, no pair gives a reasonable approximation. Only the circle with diameter 5 and circumference 22 meters have closest approximation.

If f(x)=-4x^2-6x-1 and g(x)=-x^2-5x+3, find (f+g)(x)

Nookie1986 [14]

Answer:

f(x)=-4x^2-6x-1

g(x)=-x^2-5x+3

(f+g)(x) = (-4x^2-6x-1) + (-x^2-5x+3)

-4x^2 - 6x - 1 -x^2 - 5x + 3

= -5x^2 - 11x + 2
