Answer:
6^10
Step-by-step explanation:
We know that a^ -b = 1/ a^b
So 1/ a^-b = a^b
1/6^-10 = 6^10
Answer:
cubic feet
Step-by-step explanation:
Let r, h denotes radius and height of the tree's trunk.
Radius of the tree's trunk = 2 feets
Height of the tree's trunk = 15 feets
The tree's trunk is in the shape of a cylinder.
Volume of cylinder (tree's trunk) ![=\pi r^2h](https://tex.z-dn.net/?f=%3D%5Cpi%20r%5E2h)
Put ![r=2\,,\,h=15](https://tex.z-dn.net/?f=r%3D2%5C%2C%2C%5C%2Ch%3D15)
Volume of the tree's trunk
cubic feet
Put ![\pi=\frac{22}{7}](https://tex.z-dn.net/?f=%5Cpi%3D%5Cfrac%7B22%7D%7B7%7D)
So,
Volume of the tree's trunk
cubic feet
Answer:
2.8
Step-by-step explanation:
You have to divide 0.42 by 15%.
0.42 / 15% = 2.8
Answer:
y + 3 = -6(x + 9) or y = -6x - 57
Step-by-step explanation:
We can use the point-slope form for this situation.
Point-slope form: y - y₁ = m(x - x₁), where m = slope and (x₁, y₁) are given coordinates.
Plug in: y + 3 = -6(x + 9)
This can be changed to the more common slope-intercept form.
Multiply: y + 3 = -6x - 54
Subtract: y = -6x -57
