<h3>Answer:  9/50</h3>

Explanation:

Any percentage converts to that number over 100.

So 18% would convert to 18/100

We then reduce the fraction by dividing each part by the GCF 2

18/2 = 9

100/2 = 50

The fraction 18/100 fully reduces to 9/50

Find f f'(x)=1+3sqrt(x) f(4)=25
wlad13 [49]
It appears that you have a derivative and want to integrate...

dy/dx=1+3√x 

y(x)=x+(2/3)x^(3/2)+C  you are given that f(4)=25 so we can solve for the constant of integration...

y(4)=25=4+16/3+C

21=16/3+C

(63-16)/3=C

47/3=C so

f(x)=x+(2/3)x^(3/2)+47/3

f(x)=(3x+2x^(3/2)+47)/3

What is the average rate of change from -3 to 0 of the function represented by the graph?
lbvjy [14]

Average rate of change = change in y ÷ change in x

We already know the change in x because we are measuring the x values from -3 to 0.

change in x = 0-(-3) = 3

To find the change in y find the difference between the corresponding y-values when x=0 and when x=-3.

change in y = 0.5-2 = -1.5

average rate of change = -1.5/3 = -0.5

answer: -0.5

3x^2 + 64 = 2x^2/2 find the roots of the quadratic equation
Reil [10]

Answer:

4√2i , -4√2i.

Step-by-step explanation:

3x^2 + 64 = 2x^2/2

3x^2 + 64 = x^2

2x^2 + 64 = 0

2x^2 = -64

x^2 = -32

x = +/- √-32

x = +/- √16* -2

x = +/- 4√2 i.
