Step-by-step explanation:

Hey There so the first step of this problem is to find the formula for circumference

$C=2\pi r$

given some of the values we can form an equation to solve for the radius (r)

$31.4=3.14(2)r\\3.14(2)=6.28\\31.4=6.28r\\\frac{31.4}{6.28} =5$

so we can conclude that the radius is equal to 5

Answer:

C) 5 ft

Step-by-step explanation:

Equation used: C=2πr

This isn't a hard question once you understand the basics of it. The radius squared by 2 equals the diameter, and other way around. Your going to divide the circumference by the pie (π).

31.4 ÷ 3.14 = 10

Now you'll do 10/2 to equal 5.

What is the minimum value for g(x)=x2−10x 16? enter your answer in the box.

motikmotik

The minimum value for g(x)=x² - 10x + 16 is -9

<h3>How to determine the minimum value?</h3>

The function is given as:

g(x)=x² - 10x + 16

Differentiate the function

g'(x) = 2x - 10

Set the function 0

2x - 10 = 0

Add 10 to both sides

2x = 10

Divide by 2

x = 5

Substitute 5 for x in g(x)

g(5)=5² - 10*5 + 16

Evaluate

g(5) = -9

Hence, the minimum value for g(x)=x² - 10x + 16 is -9

Create a matrix that is equal to F+G. The first matrix below is named F and the second matrix below is named G. Name the new mat

likoan [24]

F+G:

$F+G=\begin{bmatrix}{-1.8} & {-8.6} & {} \\ {2.85} & {-1.4} & {} \\ {-1.8} & {5.1} & {}\end{bmatrix}+\begin{bmatrix}{1.32} & {-1.9} & {} \\ {2.25} & {0.0} & {} \\ {-6.2} & {1.4} & {}\end{bmatrix}$

Then, add the elements that occupy the same position:
