Answer:
14
Step-by-step explanation:
We solve this by using 2 to open the bracket
(3+4)2 is the same as 2(3+4)
2(3)+2(4)
=6+8
=14
OR
(3+4)2 is the same as 2(3+4)
So we can solve the one inside the bracket first
=2(7)=14
Answer:
ans=(-2,2)
Step-by-step explanation:
let the end point of circle diameter (-1,5) and (3,-1) be (x1,y1) and (x2,y2) respectively
using mid point formula
(x,y)=(-1,5)/2+(-3,-1)/2 [center point is equal to mid point of diameter)
= (-1+(-3))/2+(5-1)/2
=(-2,2)
center coordinate of circle=(-2,2)
Answer:
$121
Step-by-step explanation:
A suitable calculator or spreadsheet can tell you the payment amount for the given loan values. The annual interest rate will be 12 times the monthly, rate, or 2.4%. The number of monthly payments in 12 years is 12×12 = 144.
__
A calculator shows the monthly payment will be about $121.
__
If you want to figure this "by hand," the amortization formula is used.
A = Pr/(1 -(1+r)^-t)
where P is the loan amount, r is the monthly interest rate, and t is the number of months.
A = 15100(0.002)/(1 -(1.002^-144)) ≈ 120.789 ≈ 121
The monthly payment would be $121.
Answer:
$5659.11
Step-by-step explanation:
We are given;
- Time of loan maturity is 5 years
- Rate of compound interest is 7% compounded quarterly
- Principal amount of the car is $4000
We are required to determine the total amount he paid at the end of 5 years..
The concept being tested is compound interest;
We are going to use the compound interest formula;
Amount = P(1+r/100)^n
Where P is the the principal amount
r is the rate of interest
n is the interest periods
In this case;
n = (5 × 4) = 20
r = 7 ÷ 4 = 1.75 ( as the money was compounded quarterly)
Thus;
Amount =$ 4000 ( 1 + 1.75)^20
= $4000 (1.0175)^20
= $5659.11
Therefore, the money that Joe will have paid at the end of 5 years is $5659.11
1. a(x+b)
2. ax+ab
example:
2(x+3)
=2.x + 2.3
=2x + 6
