An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

F(x) = -x² – 10x + 16<br> Find f(-7)

Gala2k [10]

Answer:

-5

Step-by-step explanation:

or, f(x) = -x^2+10x+16

or, f(7) = (-7)^2+10*-7+16 (-7*-7=49)

=49-70+16

=65-70

=-5

A man deposits $ 14,850 into a bank, which pays 4% interest that is compounded

Ganezh [65]

Given:

Principal = $14850

Rate of interest = 4% compounded semiannually.

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for amount is:

$A=P\left(1+\dfrac{r}{n}\right)^{nt}$

Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded and t is the number of years.

The interest is compounded semiannually, so n=2.

Putting $P=14850, r=4, n=2, t=3$ in the above formula, we get

$A=14850\left(1+\dfrac{0.04}{2}\right)^{2(3)}$

$A=14850\left(1+0.02\right)^{6}$

$A=14850\left(1.02\right)^{6}$

On further simplification, we get

$A=14850(1.12616242)$

$A=16723.511937$

$A\approx 16723.51$

Therefore, the amount in the account after three years is $16723.51.
