<h2>527.52</h2>

Step-by-step explanation:

radius (r) = 6

height (h) = 8

total surface area = 2π×r×h + 2πr²

= (2×3.14×6×8) + (2×3.14×6×6)

= (301 44) + (226.08)

= 527.52

Magnus purchased a new car for $35,865. It depreciates about 3.6% each year. What is the value of the car after 10 years?
Naddik [55]
1 year = 3.6 % depreciation
100-3.6=96.4

so you do 35,865 ×0.964 = 34,573.86

so the price after a year is £34,573.86

to find out what the price is after 10 years you do 34,573.86 (0.964) to the power of 10
which equals £23961.73

I hope that was helpful :)

If j(x) = x4 - 81, and k(x) = x + 3 then j(x) k(x) =
Bad White [126]
Hi there!
The question here is asking us to multiply two functions together - j(x) and k(x). First, we need to determine the expressions for j(x) and k(x). Since this is given, we can move straight onto multiplying the two functions together, which will give us our answer.
j(x) × k(x)
Substitute expressions - 
(x⁴ - 81)(x + 3)
Simplify - 
(x⁴ - 81)(x + 3)
x⁵ + 3x⁴ - 81x - 243
Therefore, the answer is x⁵ + 3x⁴ - 81x - 243. Hope this helped!
