5(−2) + (2−)2 <br> when =3 and =−2
lyudmila [28]

Answer:

36 is the final value for the equation you posted

Step-by-step explanation:

We are told that = 3 and = −2.

Let's plug these values into the equation.

= (5 ( − 2) + (2 − )^2)

= (5 (3 − 2(−2)) + (2 − 3)^2)

= (5 (3 + 4) + (−1)^2)

= (5 (7) + 1)

= 35 + 1

= 36

The population in a small city increased from 1250 people to 2780 people. What is the percent of increase in the number of peopl
Zarrin [17]
<h3>Answer: Choice B) 122%</h3>

==========================================

Work Shown:

A = 1250 is the initial amount

B = 2780 is the new amount

C = percent change = unknown for now

The formula to use is

C = [ (B-A)/A ] * 100

to calculate the percent change.

Basically we calculate the change (B-A) first and then divide that over the original amount A to compute the decimal form of the answer, which is then converted over to percentage form. The "100" tacked on at the end is what converts from decimal to percent form.

---------

C = [ (B-A)/A ] * 100

C = [ (2780 - 1250)/1250 ] * 100

C = (1530/1250)*100

C = 1.224 * 100

C = 122.4%

C = 122%

---------

The positive C value indicates we have a percent increase. If C were negative, then we'd have a percent decrease.

Try dividing 400 by ten you'll get 40 (or just remove a zero or decimal point to the left when dividing by 10)

PLEASE HELP ASAP!!!
Dafna1 [17]

Answer:

Step-by-step explanation:

Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula

A(t)=P(1+\frac{r}{n})^{(n)(t)}

Here's what we have:

The amount after a certain time that she has in the bank is 4672.12; that's A(t).

The interest rate in decimal form is .18; that's r.

The number of times the interest compounds is 12; that's n

and the time that the money is invested is 3.5 years; that's t.

Filling all that into the formula:

4672.12=P(1+\frac{.18}{12})^{(12)(3.5)} Simplifying it down a bit:

4672.12=P(1.015)^{42} Raise 1.015 to the 42nd power to get

4672.12 = P(1.868847115) and divide to get P alone:

P = 2500.00

She invested $2500.00 initially.
