Surface area = 2 pi (3x-2)^2 + 2 pi (3x -2) ( x + 3)
= 2 pi (9x^2 - 12x + 4 + 3x^2 + 7x - 6
= 2pi(12x^2 - 5x - 2)
Its D
Answer:
Jed's Market
Step-by-step explanation:
Find out the cost of one candy bar for each store:
Smith's:
- 9.00 ÷ 3 = $3.00
Green's:
- 10.00 ÷ 4 = $2.50
Jed's:
- 12.00 ÷ 5 = $2.40
Wan's:
- It already tells you the price for each: $2.75
Finding the best deal:
- Look at all our costs per 1 candy bar. Which one has the smallest price?
- Because $2.40 is the smallest price, Jed's Market has the best buy.
I hope this helps!
Answer:
Step-by-step explanation:
We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.
That's written as 5.6 x 10⁻¹⁷ .
(To change 5.6 into the original number, you'd need to
move the decimal point 17 places backwards.)
Thickness of the plate before polishing = 2.342
Thickness of the plate after polishing. = 2.087
How much was removed = 2.342- 2.087 = 0.255
Hence , the answer 0.255 which is option B
