Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

f(8) = -1 → Coordinate (8, -1)

f(6) = 0 → Coordinate (6, 0)

Step 2: Find slope m

Substitute [SF]: $m=\frac{0+1}{6-8}$
Add/Subtract: $m=\frac{1}{-2}$
Simplify: $m=\frac{-1}{2}$

Step 3: Write Function

Substitute into general form.

Point 1: y + 1 = -1/2(x - 8)
Point 2: y = -1/2(x - 6)

A cone has radius 9 and height 12. A frustum of this cone has height 4.

Rom4ik [11]

The radii of the frustrum bases is 12

Step-by-step explanation:

In the figure attached below, ABC represents the cone cross-section while the BCDE represents frustum cross-section

As given in the figure radius and height of the cone are 9 and 12 respectively

Similarly, the height of the frustum is 4

Hence the height of the complete cone= 4+12= 16 (height of frustum+ height of cone)

We can see that ΔABC is similar to ΔADE

Using the similarity theorem

AC/AE=BC/DE

Substituting the values

12/16=9/DE

∴ DE= 16*9/12= 12

Hence the radii of the frustum is 12

You roll a fair number cube. What is the likelihood you will land on a number greater than 4?

Alekssandra [29.7K]

Answer:

1/3

Step-by-step explanation:

There are 6 faces on a number cube.

We know that 2 of those faces are greater than 4.

So,

2 out of 6 faces=2/6=1/3
