A suggestion: x^4-x^3-8x+8 = (x - 1)( x - 2)( x^2 +2x + 4);

x^4-x^3-8x+8 = (x - 1)( x - 2)( x^2 +2x + 4);

You want to buy a house in 9 years. The estimated cost is $175,800.00. You want to make a 20% down payment and closing costs are 7%. How much in totality

Answers

Given:
buy a house in 9 years.
Estimated cost of the house = 175,800
down payment = 20%
closing cost = 7%

down payment:
175,800 x 20% = 35,160

closing cost:
175,800 x 7% = 12,306

Amount to save: 35,160 + 12,306 = 47,466

monthly savings:
9 years x 12 months = 108 months

47,466 / 108 = 439.50 savings per month.

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 2 amperes when the resistance is 770 ohms. What is the current when the resistance is 808 ohms? Round your answer to two decimal places if necessary.

Answers

Answer: The value of the current is 1.91 A.

Step-by-step explanation:

From the question, the current I in an electrical conductor varies inversely as the resistance R of the conductor.

The equation can be written as,

I=(K)/(R)

Here, K is the proportionality constant and R is the resistance.

It is given in the problem that the current is 2 amperes when the resistance is 770 ohms.

Calculate the value of K by using above expression.

Put I= 2 A and R= 770 ohm.

2=(K)/(770)

K=1540

Calculate the value of the resistance when R= 808 ohms.

I=(K)/(R)

Put K= 1540 and R= 808 ohms.

I=(1540)/(808)

I=1.91 A

Therefore, the value of the current is 1.91 A.

Over which interval is the graph of f(x) = –x2 + 3x + 8 increasing? (–∞, 1.5)

(–∞, 10.25)

(1.5, ∞)

(10.25, ∞)

Answers

The answer for this question is (-infinity,1.5) because
when f(x) is increasing f'(x)  > 0
-2x + 3 > 0
-2x > -3
 x< 3/2 or 1.5

Patrick wants to estimate the number of rabbits on his university campus. One day he catches 25 rabbits. He puts a tag on each rabbit. He then releases the rabbits back onto the university campus. The next day he catches 16 rabbits. 5 of the rabbits he catches on the second day have a tag on them. Assuming that there is a fixed population size for the rabbits and that he catches the rabbits in a random way, work out an estimate for the total number of rabbits on the university campus.
