<span>Answer:
rc length=â«âšr2+(drdθ)2â‹…dθ
for a equation r=θ2,
drdθ=2θ
â´ Arc length=â«âšÎ¸4+4θ2â‹…dθ
by factoring out θ and rewriting a bit,
=â«Î¸âšÎ¸2+4â‹…dθ=12â«(θ2+4)12â‹…2θdθ
by General Power Rule,
=12⋅(θ2+4)3232+k=13(θ2+4)32+k
Let's assume that 0≤θ≤2π
Arc length=â«2Ď€0âšÎ¸4+4θ2â‹…dθ=92.9</span>
Answer:
sells 2500 candies per month
Step-by-step explanation:
m = mints
a = almond bar
c = caramels
m = 3a
1/2 c = a
m = 3750
3a = m
a = m/3
a = 3750/3
a = 1250
1/2 c = 1250
c = 2 * 1250
c = 2500
Answer:
16
Step-by-step explanation:
80 divided by 5 is equal to 16
16 multiplied by 1 is equal to 16
Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest
<em><u>Solution:</u></em>
Given that Skippy has a total of $10,000 to split between two investments
One account offers 4% simple interest, and the other account offers 8% simple interest
Total interest earned = 500
Number of years = 1
Let the principal with rate of interest 4 % is x
So the principal for rate of interest 8 % is 10000 - x
Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest
Simple interest is given as:
Where "p" is the principal and "r" is the rate of interest and "n" is the number of years
Therefore,
Therefore skippy should invest $ 7500 in account offering 4 % interest
And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest
