What is the value of y?
Fiesta28 [93]

Answer:

y = 126.43

Step-by-step explanation:

Essentially what you have is the Cosine(50)

Cos(50) = adjacent / hypotenuse

adjacent = 122

hypotenuse = ?? = y

Solve

Cos(50) = 122/y         Multiply both sides by y

y*cos(50) = 122         Divide by cos(50)

y = 122 / cos(50)       Find the value of cos(50)

y = 122 / 0.96497     Divide

y = 126.43

Please help! 25 points!<br> Write the equation of a line with slope 3/2 and Y-Intercept -2.
Juli2301 [7.4K]
Hello there!

For this question, we can use slope-intercept form of a line. The following equation is the format for slope-intercept form:
y=mx+b

In this equation, m is the slope and b is the y-intercept. The slope and y-intercept is given. Thus, we just "plug in" the given values into the equation to get our answer. Replace "m" with "3/2" and replace "b" with "-2". After doing so, you get the following equation for the line.

y= \frac{3}{2} x-2

That should be your answer. Hope this helps! :)

The length of the carpet is 2a2 and width is 3a. Find the area of the carpet.<br> HELP ME PLEASE
jenyasd209 [6]

Answer:

6a^{3}

Step-by-step explanation:This is a very simple question.

We all know that the equation or formula for area is...

<em>A= L*W</em>

So multiply...

2a^{2} *3a= 6a^{3}

Since 3a has an exponent power of 1 and you add the exponent power when multiplying...

The result would be... 6a^{3}.

Hope this helps:)
