Answer:
-2(x^2+15)
Step-by-step explanation:
f(x) = −2(x − 4)^2 + 2.
Expanding (x-4)^2
(x-4)(x+4)
x(x+4)-4(x+4)
x^2+4x-4x-16
x^2-16
F(x) = -2(x^2-16)+2
-2x^2-32+2
-2x^2-30
-2(x^2+15)
Answer:
4% sales tax
Step-by-step explanation:
Take the original costs and subtract it from the price after sales tax.
$84.24-$81= $3.24
Divide 3.24 by 81
this gives you .04, now either multiply by 100 or move the decimal two places to the right to convert the decimal to a percentage.
Answer:
increase - $2256
price - $50256
Step-by-step explanation:
multiply the percent (in decimal form) by the original cost
48000(0.47)=2256
the increase is $2256
to find the price of it, add the two prices together.
48000+2256=50256
The amount of sales before growth according to the article is $153.85 million
<h3>How to find sales before growth?</h3>
let
- Sales before growth = x
- Percentage growth = 30%
- New sales = $200 million
200 = x + (30% × x)
200 = x + (0.3 × x)
200 = x + 0.3x
200 = 1.3x
x = 200/1.3
x = 153.846153846153
Approximately,
x = $153.85 million
