Answer:
24π cm
Step-by-step explanation:
s = (∅/360) * 2πr
s = (216/360) * 2π(20)
s = (216/360) * 2 * 20 * π
s = 24π cm
Answer:
(3^2) - n
Step-by-step explanation:
For this problem we will take it step by step to build the expression:
raise 3 to the 2nd power
= 3^2
then find the difference of the result and n
= (3^2) - n
Hence, your final expression should be (3^2) - n.
Cheers.
The line parallel to y= 4x+ 5 passing through point (-2, 1) is y = 4x + 9
<h3>Parallel Equations</h3>
The given equation is:
y = 4x + 5
Compare y = 4x + 5 with the equation y = mx + c
m = 4, c = 5
The equation parallel to y = 4x + 5 will also have a slope, m = 4
The point-slope form of the equation of a line is given as:
y - y₁ = m(x - x₁)
substitute m = 4, x₁ = -2 and y = 1 into the equation above
y - 1 = 4(x - (-2)
y - 1 = 4(x + 2)
y - 1 = 4x + 8
y = 4x + 8 + 1
y = 4x + 9
Therefore the line parallel to y= 4x+ 5 passing through point (-2, 1) is y = 4x + 9

25 divided by 2305 is 0.0106
Answer:
A=920 ft.
Step-by-step explanation:
Using the formulas
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=8·20+17·20+15·20+1
2·﹣84+2·(8·17)2+2·(8·15)2﹣174+2·(17·15)2﹣154=920
