Answer is -7/2
Gradient or slope is found by change in y over change in x.
Or
(y2 - y1) over (x2 - x1)
So
(-2 -5) over (4-2)
= -7/2
Since a sphere's surface area is 4πr², we then need to find r as a function of time t, which is 9t (since it increases by 9 every second)+0 (the initial value)=9t. Plugging it in, we get 4π(9t)²=4π*36t²=144πt²
Answer: She would have 16 bags of trail mix.
Step-by-step explanation: Since one bag of trail mix contains 1/8 of a pound. You need to add how much it will take to make 2 pounds. So you keep adding 1/8 but the denominator stays the same each time you add. So it will look like this: 1/8 + 1/8 = 2/8 and you keep repeating it until you get 8/8 which equals 1 pound. Then you add 1/8 until you get 8/8 again. So 8 + 8 = 16.
Answer:
uh......
Step-by-step explanation:
Plug in the dimensions to the formula given using a handy dandy calculator for both problems.
1. The diameter of the bottom of the cone is 4 so the radius (half that) is 2. Volume = 1/3 * pi * (2)² * 6
= 1/3 * pi * 4 * 6
= 1/3 * pi * 24
= 8 * pi
≈ 25.1327 cm³
2. They give you all you need, the radius.
Volume = 4/3 * pi * (6)³
= 4/3 * pi * 216
= 288 * pi
≈ 904.7787 in³
