Answer:
- x² + x + 1 and remainder 2
Step-by-step explanation:
<u>Given</u>
Without using a synthetic division, we can use easier method to find the quotient.
<u>We know the formula:</u>
- x³ - 1 = (x - 1)(x² + x + 1)
<u>Rewrite the given as:</u>
- x³ + 1 =
- x³ - 1 + 2 =
- (x - 1)(x² + x + 1) + 2
This expression, when divided by (x - 1) leave the quotient (x² + x + 1) and a remainder of 2
Answer:
<em>Perimeter = 6x + 5.</em>
Step-by-step explanation:
The perimeter is the sum of the three sides.
Perimeter = 3x - 2 + (-5x) + 8x + 7
= 3x - 2 - 5x + 8x + 7
= 3x - 5x + 8x - 2 + 7
= 6x + 5.
9 less than means decrease by 9 or minus 9 or -9
9 less than some number (k) means k-9

So first you plug 2 in for t
4(2.72)^(-2/2)
4/2.72 (because the simplified exponent is -1)
divide and that's your answer.
Next you plug 1 in for t
4(2.72)^(-1/2)
4/sqrt(2.72) (because -1/2 as an exponent is 1/sqrt(x))
plug that into a calculator and that's your answer
For c, you plug 1 in for V(t).
1=4(2.72)^(-t/2)
1/4=2.72^(-t/2)
Here is where I get stuck because I haven't done logarithms in a year and forget how to do them but I know that's what you have to do for this problem.
In the last problem you plug x in for V(t) and I'd assume go about solving it the same as c. Sorry I couldn't be of more help.
