Answer:
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
Step-by-step explanation:
Total cost [Pool] = Fixed (membership) cost + Variable cost (per visit)
<u>Intercept</u> is part at which equation line intersects x or y axis. In pools case, it is fixed (membership) cost. <u>Slope </u> is change in y due to change in x. In pools case, it is variable cost (per visit)
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
where V = number of visits.
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
Answer:
(4+1)(4^2 - 4*1+1)
(16+1)(16^2-16+1)
Step-by-step explanation:
Sum of cubes is a common case of factorization:
The first case can be written as: (2^2)^3+1^3= 4^3 + 1^3 which can be factorized as (4+1)(4^2 - 4*1+1)
And we can solve it, and the result is 65.
The second case can be written as (2^4)^3 + 1^3= (16^3 +1^3) which can be factorized as (16+1)(16^2-16+1)=(17)*(241)=4097
The answer is 1/4 + - 1/2, which equals -1/4 as the answer.
Answer:
(i) interest = $1680
(ii) total amount = 13680
Step-by-step explanation:
Interest.
12000 × 14/100
=168000/100
=1680
Total amount.
Interest + Loan
1680 + 12000
=13680
