Sorry if that took a while to finish. I am in AP Calculus BC and that was my first time evaluating a triple integral. You will see some integrals and evaluation signs with blank upper and lower boundaries. I just had my equation in terms of u and didn't want to get any variables confused. Hope this helps you. If you have any questions let me know. Have a nice night.
Answer: 3x + (-4) = x + 2
Step-by-step explanation:
Hope it helps
<span>A.(0,8)
B.(-1,8)
C.(1.5,10)
D.(2,16)
Simply substitute the value of x to get the value of y.
y = 8x
(0,8) y = 8(0) ; y = 0
(-1,8) y = 8(-1) ; y = -8
(1.5,10) y = 8(1.5) ; y = 12
(2,16) y = 8(2) ; y = 16
The correct ordered pair is D. (2,16)</span>
No. 1.5 is a whole number while 1.5% is a percent
Answer:
P = 40.56 ft
Step-by-step explanation:
The figure is composed of a rectangle and half circle
The perimeter of the figure = the length of the borders round the figure
= W + 2L + ½(perimeter of full circle)
W = 8 ft
L = 10 ft
½(perimeter of circle) = ½(πd) = ½(3.14*8)
= 12.56 ft
Plug in the values
Perimeter of the figure = 8 + 2(10) + 12.56
= 8 + 20 + 12.56
= 40.56 ft
