According to the Rational Root Theorem, the following are potential roots of f(x) = 2x2 + 2x – 24.

Andrei [34K]

Answer:

The answer is 3 and (-4).

Step-by-step explanation:

We are given an equation 2x² + 2x – 24.

Let us assume that the equation is equal to zero.

2x² + 2x – 24 = 0

Now, divide whole equation by 2 we get,

x² + x – 12 = 0

x² + 4x – 3x – 12 = 0

x(x + 4) – 3(x + 4) = 0

(x – 3) (x + 4) = 0

x = 3, -4

Thus, The actual roots of f(x) are 3 and (-4).

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
