Answer:

1

Step-by-step explanation:

To find the slope of a line, you need to find how much it rises for a certain amount of run. Here, the line rises from -3 to 1, which is a rise of 4, while "running" from -1 to 3, or a run of 4. 4/4=1. Hope this helps!

Answer:

Slope (m) =

ΔY

ΔX

=

1

1

= 1

θ =

arctan( ΔY )

ΔX

= 45° =

1

4

π

ΔX = 3 – -1 = 4

ΔY = 1 – -3 = 4

Distance (d) = √ΔX2 + ΔY2 = √32 = 5.6568542494924

Equation of the line:

y = x – 2

When x=0, y = -2

When y=0, x = 2

Step-by-step explanationSlope (m) =

ΔY

ΔX

Grapes are 2.55 per pound and on two separate occasions Dana went to the store to
fomenos

Answer: $11.48

Step-by-step explanation:

First of all, you have to multiply 3.25 by 2.55 because the grapes are 2.55 per pound. That makes 8.2875 for the first occasion. Next, you have to multiply 1.25 by 2.55 for the second occasion. That makes 3.1875. You then have to add 8.2875 and 3.1875. You get 11.47500, and that rounded to the nearest cent is $11.48.

Suppose a set of data about the spread (in hundreds of acres) of a food-borne bacteria (after t weeks) in lettuce has the follow
Alexxandr [17]

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes

What is the ratio between 5 footballs and 9 baseballs
____ [38]

Answer:

5:9

Step-by-step explanation:

It's just a way to set up ratios. Whichever number is said first gets put down first, then the number after gets put after.

So, 5:9

Or, you could write it as 5 footballs to 9 baseballs.

This is just my simple understanding of what you're asking since you asked what the ratio is.

Hope I helped!
