Answer:
d. x^5(x^2 - 1)
Step-by-step explanation:
x^7 - x^5
Factor out x^5
x^5(x^2−1)
Consider x^2−1. Rewrite x^2−1 as x^2−1^2. The difference of squares can be factored using the rule: a^2 - b^2 =(a−b)(a+b).
(x−1)(x+1)
Rewrite the complete factored expression.
x^5(x−1)(x+1)
Simplify.
(x^2 - 1)x^5
Swap terms to the left side.
x^5(x^2 - 1)
Answer: D. [tex]x^{5} (x^{2} -1)[/tex]
Step-by-step explanation:
x^5 (x^2-1)
x^5 (x^2-1^2)
x^5 (x+1)(x-1)

The radius of a truck tire is 11 inches. Approximately how far will the truck have traveled after 3 rotations of these tires? Use 3.14 for . Round to the nearest tenth.
Answer:
207.2in
Step-by-step explanation:
Hey There!
So to solve this problem we need to find the circumference of the circle and multiply that by 3 because that is how many rotations the tire would have made
C=2πr
where r = radius
Now we plug in the values
C=2(3.14)11
3.14*2=6.28
6.28*11=69.08
So one full rotation would have traveled 69.08 inches
Now we have to multiply that by 3 becasue they want us to find the distance traveled after three rotations
3*69.08=207.24
Now we round to the nearest tenth
so after 3 rotations the truck will have traveled 207.2in

90 minutes in fraction hour?
Answer:
1.5 Hours
Step-by-step explanation:
So, 90 minutes is between 1 hour and 2 hours (2 x 60 = 120 minutes). It is exactly half way between, hence 90 minutes is 1 and 1 half hours (or less formally, 1 and a half hours).
or
90 Minutes = 1.5 Hours = 1 Hour and 30 Minutes. Minutes to hours Time Converter 90 hours to minutes. This conversion of 90 minutes to hours has been calculated by multiplying 90 minutes by 0.0166 and the result is 1.5 hours.

toby is arranging books on a shelf. the shelf is 47 cm long to the nearest centimetre. each book is 2.5 cm wide to the nearest milimetre. show that toby can definalty fit 18 books on the shelf
Answer:
Yes, he can fit 18 books on the shelf.
Step-by-step explanation:
They will fit if maximum width of 18 books is less than minimum length of the shelf.
The minimum length of the shelf is 46.5 cm ( as its measured to nearest cm).
The maximum width of a book < 2.55 ( its measured to nearest 0.1 cm).
So multiplying width of books by 18 we get:
2.55*18 = 45.9 which is less than 46 so the answer is YES.

NEED HELP FAST!! A line has a slope of -3 and a y-intercept of 5. Write the equation of the line in slope-intercept form and explain how you would use the slope and y-intercept to graph the equation.
Answer:
y = -3x + 5
Step-by-step explanation:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=-3x + 5 tells us that the slope of the line is -3 and the y-intercept is at (0,5). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

Find the volume of cylinder,
4in
A) 887.9
B) 904.06
C) 15,509.3
D) 21,237.2
Answer:
D) 21,237.2
Step-by-step explanation:
V= πr^2h
D= 26
r= 13
V= π13^2(40)
V = 169(40)π
V = 6760π
V = 21226.4
A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388
feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.
Answer:
68.5 feet per minute
Step-by-step explanation:
rate of descent = feet / minute
First you need to find how many feet it has descended:
beginning altitude- ending altitude = total feet descended
5717 feet - 3388 feet = 2329 feet
To figure out the rate of decent we will divide
2329 feet / 34 minutes = 68.5 feet per minute
The hot air ballon descended 68.5 feet per minute for 34 minutes.
A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?
Answer:
1540
Step-by-step explanation:
First find the new price after the markup
The markup is
770 * 150%
770 * 1.5
1155
Add this to the original price
770 + 1155
1925
Now find the discount
1925*20%
1925*.20
385
Subtract this amount from the 1925
1925-385
1540
The final price is 1540
Answer:
Solution given:
cost price [c.p] of TV =$770
MP=c.p+ 150% of c.p=$770+150/100×770=$1925
discount [D]=20%
now
discount amount=D% of MP=20/100×1925=$385 is your answer.
$385 was the discount price on the plasma screen TV.
