The function LaTeX: f\left(x\right)=2\cdot5^xf ( x ) = 2 ⋅ 5 x can be used to represent an exponential growth curve. Which of th

masha68 [24]

Answer:

(2,20)

Step-by-step explanation:

The given function is

$f(x) = 2 \cdot \: {5}^{x}$

To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;

For the first point we substitute x=3 and f(x)=250

$250= 2 \cdot \: {5}^{3} \: \\ 250 = 2 \times 125 \\ 250 = 250$

This is true.

For the second point (2,20), we put x=2 and y=20 to get:

$20= 2 \cdot \: {5}^{2} \\ 20 = 2 \times 25 \\ 20 = 50$

This is false, hence (2,20) does not lie on this curve.

For (1,10), we have:

$10= 2 \cdot \: {5}^{1} \\ 10 = 10$

This is also true

Finally for (2,50), we have;

$50= 2 \cdot \: {5}^{2} \\ 50 = 2 \times 25 \\ 50 = 50$

This is also true.

frozen [14]

Answer:

d = 167.7 m

Step-by-step explanation:

We have,

Mrs. Tyner drove about 150 km east from Pearland, to Houston, Texas. She drove about another 75 km north to Dallas.

It is required to find the approximate air distance from Pearland to Dallas, Texas.

The resultant vector will give the approximate air distance. So,

$d=\sqrt{150^2+75^2} \\\\d=167.7\ m$

So, the approximate air distance from Pearland to Dallas, Texas is 167.7 m.

Find the value of x. log 2 x = 3 A. 5 B. 6 C. 8 D. 9

Nataly_w [17]

Answer: Option C

$x =8$

Step-by-step explanation:

To solve this problem use the properties of the logarithms.

We know that the inverse function of $y = log_2 (x)$ is $y = 2 ^ x$ .

So when composing the function with its inverse function we have to:

$2 ^ {log_2 (x)} = x$ .

Now apply this property on both sides of the equation

$log_2(x) = 3\\\\2^{log_2(x)}=2^3\\\\x = 2^3\\\\x = 8$

the answer is the option C
