Answer:

cos(m∠B) = 2√5/5

Step-by-step explanation:

Easiest way is to guess and check on this problem. When you take the cos(m∠B), you would get 6/3√5, rationalized to 2√5/5. That would be the correct answer.

Answer:

Option 1

Step-by-step explanation:

Cos B = \frac{adjacent}{hypotenuse}

<u><em>Where adjacent = 6, Hypotenuse = 3√5</em></u>

Cos B = \frac{6}{3\sqrt{5} }

Cos B = \frac{2}{\sqrt{5} }

Cos B = \frac{2\sqrt{5} }{5}

Does this graph show a function? Explain how you know.
beks73 [17]

Answer:

No, the graph fails the vertical line test

Step-by-step explanation:

To determine if the graph is a function, we can use the vertical line test.

Use a vertical line, if the vertical passes through two or more points, the graph is not a function

Looking at the y axis ( which is a vertical line), it passes through two points

This means the graph is not a function

No, the graph fails the vertical line test

if joe and jim combined their hourly pay,they would have $16. jims hourly pay is $1.50 more than joes. find each bous hourly pay
evablogger [386]
Joe : x
jim : y

x+y=16
y=1.50+x

x + 1.50 + x = 16

2x = 14.5

x = 7.25

7.25 + y = 16

y= 8.75

Joe : $7.25
Jim : $8.75

Whats the suface area?
Fiesta28 [93]

We can see that

There are four triangle on the surface

and five squares

For finding surface areas , we will find area of each surface and then add them

Calculation of area of triangle:

We are given

base=b=8

height=h=10

now, we can use area formula

A=\frac{1}{2}*b*h

A=\frac{1}{2}*8*10

A=40

Calculation of area of square:

base=width=8

A=8*8

A=64

There are four triangle and five squares on the surface

so, we can find surface area

SA=4* triangle + 5*square

SA=4*40+5*64

SA=480ft^2

so, surface area is 480ft^2.............Answer
