The answer is a) 12m^3 + 10n^2
Y = a x² + b x + c
y = 0.0473809524 · 20² + 2.221428571 · 20 - 0.005952381 =
= 18.95236 + 44.42875 - 0.05952381 = 63.374978 ≈ 63.4
Answer: C ) 63.4 ft.
Answer:
i believe the answer is 3pi/4
Answer:
y = 3x
Step-by-step explanation:
Slope equation:
y2 - y1
--------
x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
<u>(0,0)</u> <u>(2,6)</u>
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x
Hope this helped :)
Answer is 160
explanation: add all of them up and divid by how many numbers are in the data set
74+81+77+88=320
then divid 320 by 4 =160
