Answer:

Step-by-step explanation:

When a quantity is raised to a fractional power, you need to root it to the power of the denominator.

For example, (-64)^(1/2) = √(-64) 

Since you are taking the root of a negative, you will need to put an i (imaginary) in your answer.

Ian earns £420 a week after a 5% rise. What was his pay before?

belka [17]

It turns out that 5% of 400 is 20.

(1/20)*400=20.

So Ian was being paid £400 a week before he was given a pay rise.

22. A storage container is shaped like a rectangular prism. The volume of the container is1,360 cubic feet. The area of the base

Dovator [93]

The volume of the rectangular prism is

$V=B\times H$

Where:

B is the base area

H is the height

Since the base area is 160 feet^2

Since the volume is 1360 feet^3

Substitute them in the rule above

$\begin{gathered} 1360=160\times H \\ 1360=160H \end{gathered}$

Divide both sides by 160 to find H

$\begin{gathered} \frac{1360}{160}=\frac{160H}{160} \\ 8.5=H \end{gathered}$

The height of the container is 8.5 feet

Write an exponential function in the form y = ab that goes through points (0,19) and (5,4617).

gtnhenbr [62]

Answer:

y = 1/2 (2)x

Step-by-step explanation:

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3 Solve each equation for a.

2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3

Cross multiply: 2b3 = 4b2 Divide both sides by b2

2b = 4 a = 2/4 = 1/2

b = 2
