Allisa [31]

Step-by-step explanation:

The x-coordinate of the vertex can be found by the formula − b 2 a, and to get the y value of the vertex, just substitute − b 2 a, into the Finding Vertex from Vertex Form It's called 'vertex form' for a reason! The vertex is just (h,k) from the equation.

The Scatter plot below shows the linear trend of the number of golf carts a company sold the month of February and a line of bes

Andrei [34K]

Answer:

Part A) $y=-5.625x+90$

Part B) see the explanation

Step-by-step explanation:

Part A) Write a function that models the number of golf carts sold as a function of the number of days in the month of February

Let

x ----> the number of days

y ----> the number of golf carts sold

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The y-intercept is the point (0,90)

so

$b=90$

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the graph

(0,90) and (16,0)

substitute the values in the formula

$m=\frac{0-90}{16-0}$

$m=\frac{-90}{16}$

simplify

$m=-\frac{45}{8}$ ---> is negative because is a decreasing function

therefore

The linear equation is equal to

$y=-\frac{45}{8}x+90$

Part B) What is the meaning of the slope as a rate of change for this line of best fit

The slope is $m=-\frac{45}{8}\ golf\ carts\ sold/days$

That means ----> every 8 days 45 less cars are sold

Anyone????????????????????

ser-zykov [4K]

Answer:

4

Step-by-step explanation:

You can use the Pythagorean theorem to find the length of the unknown side.

For that, let the unknown side be x.

Let us solve now.

2² + x² = ( 2√5)²

4 + x² = 2√5 × 2√5

4 + x² = 2 × 2 × √5 × √5

4 + x² = 4 × 5

4 + x² = 20

x² = 20 - 4

x² = 16

x = √16

x = 4

Hope this helps you :-)

Let me know if you have any other questions :-)
