How do you put f(8)=-1,f(6)=0 into point slop form?

Answer:

y + 1 = -1/2(x - 8)

<u>Algebra I</u>

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:

<u>Step 1: Define</u>

f(8) = -1 → Coordinate (8, -1)

f(6) = 0 → Coordinate (6, 0)

<u>Step 2: Find slope </u><em><u>m</u></em>

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

<u>Step 3: Write Function</u>

<em>Substitute into general form.</em>

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

A milestone occurring in which of these increments of time will be the

Marianna [84]

Answer:

A milestone occurring in 3 years of increments of time will be the farthest to the right on a timeline.

Step-by-step explanation:

Here in the given options the increments of time are given.

Here, 3 years > 8 months > 12 weeks > 60 days.

Because, 3 years ≡ (3 × 365) days ≡ 1095 days

8 months ≡ (8 × 30) days ≡ 240 days

12 weeks ≡ (12 × 7) days ≡ 84 days.

Therefore, a milestone occurring in 3 years of increments of time will be the farthest to the right on a timeline. (Answer)

Answer:

V = 896 pi m^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

We know the radius is 8 and the height is 14

V = pi (8)^2 * 14

= pi *896

How many different ways are there to choose a dozen donuts from the 4 varities at a donut shop so that you get atleast one donut

Leno4ka [110]

There are 330 different ways for choosing a dozen donuts from the 4 varieties at a donut shop. (at least one donut of every variety must be selected)

<h3>How to calculate the number of ways to select items?</h3>

There are 'r' items from 'n' different varieties (repetition allowed). Then, the number of ways to select items is given by

The number of ways = $_{n+r-1}C_r$

Where the combination $_{n}C_r$ is calculated as

$_{n}C_r=\frac{n!}{r!(n-r)!}$

<h3 /><h3>Calculation:</h3>

It is given that there are 4 varieties of donuts in a shop. I.e., n = 4

Number of donuts to be selected r = 12 (one dozen)

And also given that at least one donut of every variety has to be selected.

Since there are 4 varieties, at least one from each of these means the count is 4.

So, the remaining number of donuts to be selected is 12 - 4 = 8.

So, r becomes 8 i.e., r = 8

On substituting,

the number of ways of selecting the remaining 8 donuts = $_{4+8-1}C_4$

⇒ $_{11}C_4$

⇒ $\frac{11!}{4!(11-4)!}$

⇒ $\frac{11!}{(4!)(7!)}$

⇒ 330

Therefore, there are 330 different ways for choosing a dozen donuts from the 4 varieties at a donut shop.
