4 0

add all the angles and make them equal to 360

88 + 108 + (3x-6) + 2x = 360

196 + 5x -6 = 360

190 + 5x = 360

5x = 170

x = 34 = answer

An object is dropped from a height of 400 feet. The amount of time, in seconds, the object takes to hit the ground can be found
lidiya [134]

-16t^2+400=0

16t^2=400

take square root on both sides.

\sqrt{16t^2} =\sqrt{400}

4t=20

t=20/4

t=5

Express the recurring decimal 0.042 as a fraction in its simplest form.
rodikova [14]

Answer:

7/165

Step-by-step explanation:

This is a mixed recurring decimal (the zero is not repeating)

We take number after the decimal point     042

then we subtract  the non repeating.In this case is 0 so we not subtract anything

This will be the numerator  42

Now ,the denominator:

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990  =  7/165

7:165 = 0.0424242......

Find f(-5) of f (x) = x + 1<br> 1) 4<br> 2) 5<br> 6) 6
Alex
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4

Find f(-1), f(0), f(3) for the following function.<br> f(x)=3x<br> f(-1)=Blank
kramer

Answer:

If f(x) = 3x, this means that any number that replaces x in the parenthesis, would replace x in the right side too.

When x = -1:

f(-1) = 3(-1) = -3

When x = 0:

f(0) = 3(0) = 0

When x = 3:

f(3) = 3(3) = 9
