Here’s why:
⸻⸻⸻⸻
I am assuming that 'r' is supposed to be 'x'.

Answer:diameter of circle A is
(2r - 10) centimeters while Answer:diameter of circle B is 2r
Step-by-step explanation:
Diameter = radius/2
Circle A has a radius that is 5 centimeters less than the radius of Circle B. It means that if the radius of circle B is 5 centimeters, then the radius of circle A would be (r - 5) centimeters. Also,
The diameter of circle B would be
2 × r = 2r centimeters
Therefore, the diameter of circle A would be expressed as
2(r - 5) = (2r - 10) centimeters
Answer:
8.7 so either 8 or 9 tenth of a year
Step-by-step explanation:
<em>Is it compounded per month? I assume</em>
1. Compound interest formula
FV = PV(1+r/100k)^kn
FV is the future value,
PV is the present value,
n is the number of years,
k is the number of compounding periods per year
r% is the nominal annual rate of interest
2. Plug in numbers
3550 = 2400(1+4.6/100*12)^12*n
71/48 = (6023/6000)^12n
12n = logBase(6023/6000)*(71/48)
n = answer/12
n ≈ 8.70
Slope is rise/run
so, you go up 4 times and run across 3 times, this is a positive slope, so the slope is
slope: 4/3
the y-intercept is the line that passes the y-axis, (0, -5),
y-intercept: -5
put it together
4/3x-5
