I think you have it upside down.
When you solve a proportion, you cross multiply. You can have the same proportion just by interchanging 8 and b

a/8 = b / 15 When you cross multiply, you get
15a = 8b Try the given proportion to see what happens

This is a hexagonal prism: Volume = Area of Base (hexagon) x Height:
There are 6 equal equilateral triangles in a hexagone.
The apothem (or altitude of each triangle) = side x (√3)/2 =12(√3)/2 = 6√3
Area of ONE equilateral triangle = (side x altitude)/2:
Area of ONE equilateral triangle = (12 x 6√3)/2 = 36√3 ft²
Area of the SIX equilateral triangles = 36√3 x 6 = 216√3 ft²
VOLUME = BASE X HEIGHT = 216√3 x 15 = 3240√3 ft³

OR VOLUME = 5612 ft³

Find the equation of the tangent line at the point (1, 6). for y = 4 + 4x2 - 2x3.
Lostsunrise [7]
y = 4 + 4 x^{2}-2x^{3}  Lets \ write \ it \ y = -2 x^{3} +4 x^{2} +4

The tangential line at a certain point is just the derivative so.
y ' = -6 x^{2} +8x. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)

The tangential line at that point is
y - 6 = 2(x - 1)     (this is the answer)

A scale model of a tower is 24 inches tall and 18 inches wide. If the height of the actual tower is 60 feet, what is its width?
alex41 [277]

Answer:

45 feet

Step-by-step explanation:

To find the width of the model, we need to find the scale of the model to the actual tower.

Since we know the height of both towers, we can use that as the basis.

24 inches : 60 feet

12 inches : 30 feet

6 inches : 15 feet

So the width of the tower is 18 inches wide.

18 inches will then be equal to 12 + 7 inches : 30 + 15 feet

18 inches : 45 feet
