It is 63 students, because 84 divided by 2 is 42 then half of 42 is 21 so 21 is 25% so then you do 21 x 3 = 63

Sauron [17]

Answer:

(f ο g)(-1) = 1

Step-by-step explanation:

Given

      f(x) = \frac{8}{x+2}    

     g(x) = 4 x^{2} +2

f ο g)(-1) = f(g(-1) = f(4(-1)² + 2)

                          = f(6)

                         = \frac{8}{x+2}

                       = \frac{8}{6+2}

                      = 1

<u><em>Final answer</em></u>:-

(f ο g)(-1) = 1

What is the equation of this graphed line?
maksim [4K]

Answer:

y=-\frac{9}{8} x+7

Step-by-step explanation:

The slope is found by doing the equation \frac{rise}{run}. When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal -\frac{9}{8}.

The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.

The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

Change this radical to an algebraic expression with fractional exponents. √y^2 The exponent on y is:
Wewaii [24]
The power rule (or law of indices) related to root is given
x^{ \frac{1}{2} }=  \sqrt[2]{x}

We have \sqrt{ y^{2} }
Rewrite according to the rule we have y^{ \frac{2}{2} } = y^{1}

The exponent on y is '1'
