Plug in 0 for x and you get 5. Which is your answer :)
All you do is plug in -7 so you get f(x)=8(-7)*15 you get -56*15 which goes to -840
Answer:
16 + 6pi cm
Step-by-step explanation:
We have a square of length 4 cm
A = s^2 = 4^2 = 16
We have 3 semi circles
with radius 2
A semi circle has an area of
1/2 pi r^2 = 1/2 pi (2)^2 = 1/2 (4pi) = 2pi
There are 3 of them
3 * 2 pi = 6pi
Add the areas together for the square and the semicircles
16 + 6pi
If she deposited $600 and had $621.60 after four years, then she earned: $621.60 - $600 = $21.60 in four years. It means in one year she earned $21.60 ÷ 4 = $5.40. Now we have to find out how many percent of $600 is $5.40:
$5.40 = x% from $600
5.4 = x/100 * 600
5.4 = 600x/100 / * 100 (both sides)
540 = 600x / ÷ 600 (both sides)
x = 0.9
So the interest rate was 0.9% annually.
Now we have to find out how much is 0.9% from $1100:
$1100 * 0.9% =
= 1100 * 9/1009 =
= 9900/1000 =
= 9.9
It means in one year she would earn $9.90. After 7 years she would earn $9.90 * 7 = $69.30, so she would have in her account:
$1100 + $69.30 = <u>$1169.30</u>
It's 25 percent as it's Aa plus Bb which gives 4 combinations and one of them is the answer. thus 1/4 equals 25percent
