Answer:
y = 1/2x + 5/2
P.S, this isn't geometry really. It's more like algebra :)
Step-by-step explanation:
Step 1: Find equation of line AB
m = (5 - 1)/(-2 - 0)
m = 4/-2
m = -2
y = -2x + 1
Step 2: Find slope of perpendicular line
<em>Take the negative reciprocal of line AB</em>
m = 1/2
y = 1/2x + b
Step 3: Find <em>b</em>
6 = 1/2(7) + b
6 = 7/2 + b
b = 5/2
Step 4: Rewrite perpendicular equation
y = 1/2x + 5/2
or
y = 0.5x + 2.5
Answer: 8
Step-by-step explanation:
we know the area of a circle is
A=π r²
50.24= 3.14* r²
50.24/3.14=r^2
16=r^2
r=sqrt 16=4
diameter is 2r=2*4=8
Hi there
The formula is
A=p (1+r)^t
A future value 11700
P present value 900
R interest rate 0.0875
T time?
We need to solve for t
T=log (A/p)÷log (1+r)
So
T=log(11,700÷900)÷log(1+0.0875)
T=30.6years round your answer to get
T=31 years
Hope it helps
