We can mark "breadth" as x so lenght will be x +4 so x+x+x+2+x+2 =11
Therefore 4x+4=11
4x=7
X=7/4
So length is x+4 =7/4 +4
Answer:
-15/4
Step-by-step explanation:
The formula of interest is
A = (1/2)r²·θ
You have r = 9 m, θ = 3π/5. Then the area is
A = (1/2)(9 m)²(3π/5) = 24.3π m²
The sector area is ...
A ≈ 76.3 m²
Put the given numbers in the appropriate formula and evaluate.
A = P(1 +r/n)^(nt)
P is the principal amount
r is the annual rate
n is the number of times per year interest is compounded
t is the number of years
A is the balance in the account after t years
a. A = $6000*(1 + .045/12)^(12*17) ≈ $12,875.53
b. A = $6000*(1 + .045/4)^(4*17) = $12,839.01
for P(t) = 65- 5t
domain is [0, 13]
because intially at t = 0 total puppy available is 65 (put t = 0 in equation)
now after 13 days
P(t) = 65 - 5×13 = 65-65 = 0
no puppy available. so t has last range of 13.
similarly for second its domain is [0, ∞]
as subscribers will increase as t will increase.
for 3rd
C(t) = 65 + 5t
here t is guest so . they can only accomdate 30 guests only so t csn go to 30 only.
so domain is [0,30]
