2.37 / x = 1<br> What is x?

NeTakaya

Answer: 2.37

Step-by-step explanation:

Multiply each side by x to get rid of the denominator on the left side.

You get:

2.37 = 1x

1x = x

Therefore, 2.37 = x.

Also, any number divided by itself must be 1.

The graphs below have the same shape. f(x) = x2<br> What is the equation of the graph of g(x)?

mariarad [96]

Answer:

g(x)=(x-2)^2

Step-by-step explanation:

the equation of of the graph of g(x) is:

g(x)=(x-2)^2, since the following transformation has been done to it:

right one unit

since the equation in vertex form is g(x)=a(x-h)^2+k, it is moved two units to the right and not to the left

since g(x) has the same shape, it had not been compressed or stretched by any means, meaning that a is 1

Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year.

lilavasa [31]

Answer:

c. 12.48

Step-by-step explanation:

The earnings per share after t years can be modeled by the following equation:

$E(t) = E(0)(1+r)^{t}$

In which E(0) is the earnings last year and r is the growth rate, as a decimal.

Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year. Growth rate maintained.

This means that $E(0) = 3.50, r = 0.092$

So

$E(t) = E(0)(1+r)^{t}$

$E(t) = 3.50(1+0.092)^{t}$

$E(t) = 3.50(1.092)^{t}$

If that growth rate were maintained, how many years would it take for Brockman's EPS to triple?

This is t for which E(t) = 3*E(0) = 3*3.50 = 10.50.

So

$E(t) = 3.50(1.092)^{t}$

$10.50 = 3.50(1.092)^{t}$

$(1.092)^{t} = \frac{10.50}{3.50}$

$(1.092)^{t} = 3$

$\log{(1.092)^{t}} = \log{3}$

$t\log{1.092} = \log{3}$

$t = \frac{\log{3}}{\log{1.092}}$

$t = 12.48$

So the correct answer is:

c. 12.48

Find the sum: (2x^2 + x + 13) + (3x^2 + 2x + 1)

Pavel [41]

Answer:

5x^2 + 3x + 14

Step-by-step explanation:

(2x^2 + x + 13) + (3x^2 + 2x + 1)

Combine like terms

(2x^2 + 3x^2 + 2x+ x + 13 + 1)

5x^2 + 3x + 14
