Answer:

A 16 pi in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We need the radius

r = d/2

r = 8/2 =4

A = pi (4)^2

A = 16 pi

In a small town, electricity prices have been rising 2% each year since 2008. Which
mihalych1998 [28]
<h3>Answer: p = 0.12*(1.02)^t</h3>

Explanation:

The general exponential growth equation is

p = A*B^t

where t is the number of years that have gone by after 2008, A is the starting amount, B is the growth multiplier, and p is the price t years after 2008

We know that A = 0.12 is the starting price

The value of B is B = 1.02 which is in the form 1+r since 1.02 = 1 + 0.02 = 1+r

The r value is r = 0.02 and it is positive to represent growth. Keep in mind that 2% = 2/100 = 0.02

So we go from

p = A*B^t

to

p = 0.12*(1.02)^t

Find [-4/5]×3/7×15/16×[-14/9]​
dangina [55]

The given expression is \frac{-4}{5} \times \frac{3}{7}  \times \frac{15}{16}  \times (\frac{-14}{9}).

We need to simplify the given expression.

<h3>What is a rational number?</h3>

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.

Now group the rational numbers (\frac{-4}{5}\times \frac{15}{16} ) \times (\frac{3}{7}\times (\frac{-14}{9}))

=(\frac{-4}{16}\times \frac{15}{5} ) \times (\frac{3}{9}\times (\frac{-14}{7}))

=(\frac{-1}{4}\times \frac{3}{1} ) \times (\frac{1}{3}\times (\frac{-2}{1}))

=(\frac{-3}{4} ) \times (\frac{-2}{3})=\frac{1}{2}

Therefore, the simplified value of the given expression is \frac{1}{2}.
