Basically
Circumference = 2 * pie * radius
To get the radius u need to measure the circles distance. For example I measured a circular mirror and the distance was 10cm. This is the diameter. To get the radius I’ll divide by 2 because the radius is from the centre of the circle to the edge. So, 10 divided by 2 = 5cm. The radius is 5cm. Now,
Circumference = 2 * pie * r
r = 5. Pie = 3.14
Circumference = 2 * 3.14 * 5
= The answer
****pie is always 3.14
I hope you understood
Answer: The graph crosses the x-axis at x = 2.
Step-by-step explanation:
The root has a multiplicity of 3, meaning that it crosses the x axis at x=2.
Answer:
x=9
Step-by-step explanation:
Since the polygons are similar, the ratios of their respective sides are equal.
32/24=(x-1)/6
x-1=8
x=9
X^2+8x+x+8 simplifies to x^2+9x+8
Answer: B) A = 750(1.04)ⁿ
<u>Step-by-step explanation:</u>
The formula for compounded annually is: A = P(1 + r)ⁿ where
- A (amount accrued) = <em>unknown</em>
- P (amount invested) = $750
- r (interest rate) = 4% -->(0.04)
- t (time in years) = <em>unknown</em>
A = 750(1 + 0.04)ⁿ
= 750(1.04)ⁿ
