Answer:
x^3 + 2x^2 - 9x - 18
Step-by-step explanation:
It is (x - 3)(x + 3)(x + 2)
= (x + 2)(x^2 - 9)
= x^3 - 9x + 2x^2 - 18
= x^3 + 2x^2 - 9x - 18 (Standard Form).
Answer:
$1,061
Step-by-step explanation:
2% of 1000 is 20.
If 2% is compounded yearly, then
year one- $1,020
year two- $1,040.40
year three- $1,061.21
Rounded to the nearest whole dollar, Elaine would have $1,061 in her savings account after three years.
Answer:
if ab= ac and bc= 9 then ba=ac so there for b and a are equivalent so ac=9
Step-by-step explanation:
Answer:
the answer would be 19 because these are congruent shapes
Hope this helps:)
Step-by-step explanation:
Given:
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)
Answer: ($24,890.46, $25,109.54)
