The number 0.1111... repeats forever; therefore, it is irrational. True or False.

Rasek [7]

Answer is True. We cannot write it in rational form where both numbers are finite integers. In this case we cannot represent this number as fraction of finite integers therefore it is irrational.

Write 4x2 + 16x - 9 in vertex form. Write 5x2 - 10x + 4 in vertex form.

Marizza181 [45]

Hi king,

Write $4x^{2} + 16x - 9$ in vertex form:

f(x)= $4x^{2} + 16x - 9$

f(x)= $4(x+2)^{2} -25$

Write $5x^{2} - 10x + 4$ in vertex form:

g(x)= $5x^{2} - 10x + 4$

g(x)= $5(x-1)^{2} -1$

Have a great day.

If Sonja deposits $1,000 into a savings account at 4% simple interest, how long will it

Galina-37 [17]

Given:

Principal (P)= $1,000

Rate of interest (R)= 4% = 0.04

Simple interest (I)= $100

To find:

The time for which she deposits $1000 into a savings account at 4% simple interest.

Solution:

The formula for simple interest is

$I=P\times R\times T$

On substituting P=1000, R=0.04 and I=100 in the above formula, we get

$100=1000\times 0.04\times T$

$100=40T$

Divide both sides by 40.

$\dfrac{100}{40}=T$

$2.5=T$

Therefore, the required time is 2.5 years.
