Pi is equal to the amount of times the diameter fits around a circle, in this case, 7xPi is equal to your total cost. 7Pi=176, to find the cost per foot divid 176 by 7 foot, this gives you the amount. I hope you found this helpful.
Answer:
(a) 120 square units (underestimate)
(b) 248 square units
Step-by-step explanation:
<u>(a) left sum</u>
See the attachment for a diagram of the areas being summed (in orange). This is the sum of the first 4 table values for f(x), each multiplied by 2 (the width of the rectangle). Quite clearly, the curve is above the rectangle for the entire interval, so the rectangle area underestimates the area under the curve.
left sum = 2(1 + 5 + 17 + 37) = 2(60) = 120 . . . . square units
<u>(b) right sum</u>
The right sum is the sum of the last 4 table values for f(x), each multiplied by 2 (the width of the rectangle). This sum is ...
right sum = 2(5 +17 + 37 +65) = 2(124) = 248 . . . . square units

<span>B) (1, 5) is your best answer
B (0,6) creates the top of the kite
D (0,2) creates the bottom
A (-1,5) creates the left side of the kite
D (1,5) creates the right side (only the x is flipped, because has congruent sides of both the top, and both the bottom.

Answer:
y = 5
Step-by-step explanation:
Since BD bisects ∠ABC , then
∠ABD = ∠CBD ← substitute given angle values
5y - 3 = 2y + 12 ( subtract 2y from both sides )
3y - 3 = 12 ( add 3 to both sides )
3y = 15 ( divide both sides by 3 )
y = 5
