Which of the following exponential functions goes thru points (1,6) and (2,12)

Alexandra [31]

Answer:

Noting that e^b = 6/a

Step-by-step explanation:

Use the general expo function y = ae^(bx).

Subbing 6 for y and 1 for x, we get 6 = ae^(b), or e^b = 6/a.

Subbing 12 for y and 2 for x, we get 12 = ae^(2b), or 12/a = (e^b)²

Now let's find the value of the coefficient a. Noting that e^b = 6/a, rewrite

12/a = (e^b)² as 12/a = (6/a)².

Dividing both sides by 6/a, we get 2 = 6/a, or a = 3.

Again Noting that e^b = 6/a, e^b = 6/3, or e^b = 2.

Taking the natural log of both sides, we get b = ln 2.

Then our y = ae^(bx) becomes:

y = 3e^(ln 2·x), or y = 3·2^x

Note: next time, please share the answer choices. Thank you.

Kate bad $2,251 in here bank account. Currently, she has $1,958 in her account. What is the approximate percent of decrease in h

Fiesta28 [93]

Answer:

The answer is: 13%.

Step-by-step explanation:

At first, Kate had $2,251. Then her new balance was $1,958. The difference between the two is the amount spent:

$2,251 - $1,958 = $293.

The difference is the ratio of the amount spent divided by the original amount, to provide the decrease:

$293 / $2,251 = .13 or 13% (Approximately)

Hope this helps! Have a great day!

3. In the equation below, k is a constant. If x = 6, what is the value of k? Vk + 2 - x = 0

ehidna [41]

Answer:

Write the equation with 6 for x

Vk + 2 - 6 = 0

Vk - 4 = 0

Add 4 to both sides

Vk = 4

Divide both sides by V

k = 4/V

Two possible solutions of √11-2x=√x^2+4x+4 are –7 and 1. Which statement is true? A) Only x = –7 is an extraneous solution.

11111nata11111 [884]

Answer:

Option D)Neither solution is extraneous.

Step-by-step explanation:

we have

$\sqrt{11-2x}=\sqrt{x^{2}+4x+4}$

we know that

two possible solutions are x=-7 and x=1

Verify each solution

Substitute each value of x in the expression above and interpret the results

1) For x=-7

$\sqrt{11-2(-7)}=\sqrt{-7^{2}+4(-7)+4}$

$\sqrt{25}=\sqrt{25}$

$5=5$ ----> is true

therefore

x=-7 is not a an extraneous solution

2) For x=1

$\sqrt{11-2(1)}=\sqrt{1^{2}+4(1)+4}$

$\sqrt{9}=\sqrt{9}$

$3=3$ ----> is true

therefore

x=1 is not a an extraneous solution

therefore

Neither solution is extraneous
