How would i do number 2?

vekshin1

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

Estimate the product by rounding 9 times 54

crimeas [40]

You estimate the product by rounding to the nearest 10:

9 becomes 10 and 54 becomes 50

9 x 50 = 450

Find the length of GI in the triangle below. Show your work.

love history [14]

Answer:

<u>The length of GI is 90.06 units</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

GH = 60 units

HI = 42 units

∠H = 123°

2. Using the Law of Cosines, we can find the length of GI, this way:

GI² = GH² + HI² - 2 * GH * HI * cos ∠H

Replacing with the real values:

GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 + 2,746.8

GI² = 8,110.8

<u>GI = √ 8,110.8 = 90.06 units</u>

Geometry question need help finding the answer.

Xelga [282]

Answer: 1208.96

Step-by-step explanation:

The volume of the cylinder is $(\pi)(4^2)(4)=64\pi$

The volume of the prism is $(6)(12)(14)=1008$

So, the total volume is $1008+64\pi=\boxed{1208.96}$
