Answer:

6x²

Step-by-step explanation:

-\frac{3}{4} x\times \left( -8x\right)  =\frac{3}{4} x\times 8x

                     =\frac{3}{4} \times 8\times x\times x          

                     =\frac{24}{4} \times x^{2}

                     =6x^2

10. Select all that are true for the graph that represents
Likurg_2 [28]

Answer:

A, C and F

Step-by-step explanation:

The given function is

f(x)=5(3)^x

It is an exponential function of the form

f(x)=a(b)^x

On comparing both the functions, we get

a=5,b=3

It means the initial value is 5 and growth factor is 3.

Since both values are positive it means the given functions is an exponential growth function, therefore,

1. The graph is increasing by a common ratio of 3.

2. As x increases, y increases.

3. As x decreases, y approaches 0.

Hence, the correct options are A, C and F.

Simplify (3 + 2i)(7 − 5i).
erma4kov [3.2K]
Rule needed: i^2 = -1
Standard form a + bi

(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i

The following data values represent a population. What is the variance of the values? 7, 5, 11, 1, 11
MaRussiya [10]
The mean is 35/5=7

The variance is the average of the sum of squared differences of each element from the mean:

v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5

v=(0+4+16+36+16)/5

v=14.4
