Answer: the exact volume is 1,357.168
Step-by-step explanation:
Answer:
A correct
B is 15 not 17
C correct
D correct
E correct
F is 10 not 3.5
Step-by-step explanation:
Answer:
f(x)=(2x-7)^7(x+3)^4
When y=0, (2x-7)^7=0 and x=3.5 OR
(x+3)^4=0, and x=-3
Look at x=h or f(2)
That is 96-56-44+2 and it is not equal to 0. (x-2) is not a factor.
x^3-5x^2+6x-30
after trying 1,2, and 3, I tried 5
5/1===-5===6===-30
==1===0====6====30
(x^2-6) with no remainder
the factors are (x-5)(x^2+6)
the zeroes are 5, +/- i sqrt (6). Only one real 0.
hope this helps let me know in the comments if i'm wrong
Answer:
a) $26
b) 24.07%
c) $94.3
Step-by-step explanation:
Given that:
Before tax:
Normal price of dress = $62
Discounted price of dress = $48
Normal price of a pair of shoes = $46
Discounted price of a pair of shoes = $34
a) Before the sales tax, total savings = ($64 - $48) + ($46 - $34) = <em>$26</em>
b) Total percentage discount on total sales.
Total bill for original price = $62 + $46 = $108
Percentage discount can be found by the formula:

c) Total amount paid if the sales tax is 15%.
Amount paid with tax = Amount after discount + 15% of amount after discount
Amount after discount = $48 + $34 = $82
15% of $82 = $18.29
Amount paid with sales tax = $82 + $12.3 = <em>$94.3</em>
Answer:
c.

it's been a while since I've done this but I'm about 90% sure
