Please someone help me Find the value of x. Round to the nearest tenth

The answer is

Step-by-step explanation:

First we have to find the value of "X" which is adjacent to 26 degrees and the formula to find the "X" is:

cosθ =

cos(26) =   Now, multiply both sides by 12.

x = cos(26) (12)

x = 10.8

Now moving on to the other "X" which is opposite to 26 degrees, the formula is:

Now in order to get rid of the square, you have to square root both sides.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
