<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

$A=P[1+\dfrac{r}{n}]^{nt}$

a) The amount in the bank after 6 years if interest is compounded annually.

$A=P[1+\dfrac{r}{1}]^{t}\\\\\\A=6000[1+\dfrac{0.01}{1}]^{ 6}$

A= $6369

b) The amount in the bank after 6 years if interest is compounded quarterly.

$A=P[1+\dfrac{r}{4}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{4}]^{4\times 6}$

A= $6090

c ) The amount in the bank after 6 years if interest is compounded monthly.

$A=P[1+\dfrac{r}{12}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{12}]^{12\times 6}$

A=$6030

Hence the amount for the investment of $6000 will be a.$6369 b. $6090 and c.$6030.

What are the zeros of f(x) = x2 + 3x – 10?

Nady [450]

Step One
Factor f(x)
f(x) = (x + 5)(x - 2)

Step Two
The zeros occur when either (x + 5) = 0 or (x - 2) = 0

x + 5 = 0
x = -5

x - 2 =0
x = 2

Step 3
Record the zeros
(-5,0) or (2,0) <<<<<< answer.
