You’re finding the least common denominator do you have to find what number the denominators can go into evenly. For example number one: 4 and 6 go into 12

1/4, multiply both top and bottom by 3.
That will give you 3/12

Now te same for 5/6. Now multiply both top and bottom by 2 and the equals 10/12

Final answer 3/12, 10/12.
If you need more help just comment! :)

Assume that the risk-free rate is 8 percent the required rate of return on the market is 13 percent and the required rate of ret

lapo4ka [179]

This is the formula for computing the required rate of return in a market: E(R) = Rf + ß( Rmarket - Rf ). This is called as the Capital Asset Pricing Model (CAPM). The E(R) represents the required rate of return; the Rf is the risk-free rate; the ß is the beta coefficient (which we are looking for); and the Rmarket is the rate of return on the market. Substituting the values to this formula, you can come up with the beta coefficient of 1.4.

Fill in the missing values in the table for the quadratic function: f(x) = 1/3x^2+1

Vesnalui [34]

Answer:

[x] f(x)

[-6] 13

[-3] 4

[0] 1

[3] 4

[9] 28

Step-by-step explanation:

f(0) = (1/3)(0^2)+1 = 1

f(3) = (1/3)(3^2)+1 = 4

f(9) = (1/3)(9^2)+1 = 28

The value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after

lord [1]

For this case we have a function of the form:

$y = A * (b) ^ x$

Where,

A: initial value of an autographed baseball

b: growth rate

x: number of years

Substituting values we have:

$y = 300 * (1.05) ^ x$

For the moment when the value is at least 650 $ we have the following inequality:

$300 * (1.05) ^ x \geq 650$

Answer:

a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650 is:

$300 * (1.05) ^ x \geq 650$

Find the number halfway between 3/5 and 7/10

ANTONII [103]

The answer is 13/20

The number (n) halfway between x and y is:
n = (x + y) : 2

The number (n) halfway between 3/5 and 7/10 is:
n = (3/5 + 7/10) : 2
n = (6/10 + 7/10) : 2
n = 13/10 : 2
n = 13/10 : 2/1
n = 13/10 * 1/2
n = 13/20
