Answer:

m=2

Step-by-step explanation:

When you put a number into the inverse of a function (f^-1) you get the original number back.

Ex: f^-1(11) = (11-3)/2 = 4

f(4) = 2×4+3 = 11

So, f(-5)=-2

So, when x is -5,

f(x) = -2

f(x)=m(-5)+8

-2=m(-5) + 8

m=2

Rays PQ and PS are perpendicular to each other.<br><br> What is the measure of LRPS plzzzzz

inna [77]

Answer:

m<RPS = 53 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram shown;

m<QPR + m<RPS = 90

Given that;

m<QPR = x

m<RPS = x+16

Substitute into the formula;

m<QPR + m<RPS = 90

x+x+16 = 90

2x+16 = 90

2x = 90-16

2x = 74

x = 74/2

x = 37degrees

Get m<RPS;

Since m<RPS = x+16

m<RPS = 37 + 16

m<RPS = 53 degrees

Evaluate h-^2g for h=4 and g=32

Lady_Fox [76]

Answer:

$2$

Step-by-step explanation:

The given expression is,

$h^{-2}g$

We apply the laws of indices to rewrite as a positive index to get,

$h^{-2}g=\frac{g}{h^2}$

We substitute

$h=5,g=32$

to obtain,

$=\frac{32}{4^2}$

This simplifies to,

$=\frac{32}{16}=2$
