Answer:
128 square inches
Step-by-step explanation:
The scale factor for area is the square of the scale factor for side length. The larger octagon has an area of ...
(8/4)²(32 in²) = 4·32 in² = 128 in²
The area of octagon B is 128 square inches.
Answer:
See below in bold.
Step-by-step explanation:
A). s(t)= -16t^2+64t+200
Converting to vertex form.
s(t) = -16 (t^2 - 4t) + 200
s(t) = -16 [(t - 2)^2 - 4] + 200
s(t) = -16(t - 2)^2 + 64 + 200
s(t) = -16(t - 2)^2 + 264
The maximum height is after 2 seconds and it is 264 feet.
B) The ball hits the ground when s(t) = 0 so we have:
-16t^2+64t+200 = 0
x [-64 +/- sqrt (64^2 - 4*-16*200) ] / -32
x = 6.06, -2.06
So the answer is 6.06 seconds.
A.
the area of a polygon is/
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=

Answer:
V=140
Step-by-step explanation:
5*4=20
20*7=140
2/3x+1=5-8
Combine like terms:
2/3x+1=-3
Subtract 1 from both sides
2/3x=-4
Multiply 3x from both sides
2=-12x
Now divide -12 from both sides
=-2/12
Simplify and you get -1/6 for your answer
