If 5x:(x-2) = 11:3 , find the value of x ?​
Masteriza [31]

Answer:

x = -11/2

Step-by-step explanation:

The ratios need to stay the same

5x        11

----- = -------

x-2       3

Using cross products

5x*3 = (x-2) 11

15x = 11x - 22

Subtract 11 from each side

15x-11x = -22

4x = -22

x = -22/4

x = -11/2

The function LaTeX: f\left(x\right)=2\cdot4^xf ( x ) = 2 ⋅ 4 xcan be used to represent an exponential growth curve. What is the
nikklg [1K]

Option B: 4 is the multiplicative rate of change of the function

Explanation:

The exponential growth function is f(x)=2(4)^x

We need to determine the multiplicative rate of change of the function.

First, let us determine the values of function.

x        y

1        8

2       32

3       128

4       512

Since, the multiplicative rate of change of an exponential function is the number by which the next term is increasing or decreasing.

Thus, the multiplicative rate of change of the function is given by

Multiplicative rate of change of the function = \frac{32}{8} =4

Multiplicative rate of change of the function = \frac{128}{32} =4

Multiplicative rate of change of the function = \frac{512}{128} =4

Thus, the multiplicative rate of change of the function is 4

Therefore, Option B is the correct answer.

Vilka [71]

Answer:

2nd option

Step-by-step explanation:

The zeros are the points on the x- axis where the graph crosses.

Since the graph crosses the x- axis at x = - 1 and x = 5, then

The zeros are x = - 1 and x = 5
