pychu [463]

Answer:

f(x)=4x(x-3)

Vertex=3/2, -9

Step-by-step explanation:

First, factorize it.

That is equal to 4x(x-3)

Therefore, x intercepts are 0 and 3, as at least one of them need to be 0.

To find the vertex, first find the x of the vertex, which you can do by finding the average of the x intercepts, so it will be 3/2

Then, find the y, by making x in the original equation equal 3/2. This will give us -9 as the y.

The vertex will by 3/2, -9

Sam earned $40 on his investment of $400. He earned 5% interest on his investment. How long did Sam leave his money in the bank?

gogolik [260]

Answer:

2yrs

Step-by-step explanation:

Given parameters:

Amount of interest earned = $40

Principal = $400

Interest rate = 5%

Unknown:

Time taken for the money to be in bank = ?

Solution:

The formula for interest is given as:

I = $\frac{PRT}{100}$

Where I is the interest

P is the principal

R is the rate

T is the time

So;

100I = PRT

T = $\frac{100I }{PR}$ = $\frac{100 x 40}{400 x 5}$ = 2yrs
