Using the graph below, calculate the average rate of change for f(x) from
x = 0 to x =2

1) -4

2) -2

3) 2

4) 4

Answers

Answer 1

Answer:

Step-by-step explanation:

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

a = 0,

f(a) = f(0) = -2 (from the graph given)

b = 2,

f(b) = f(2) = 5 (from the graph)

Plug in the values

Average rate of change = [tex] \frac{5 - (-2)}{2 - 0} [/tex]

[tex] = \frac{7}{2} [/tex]

= 3.5 ≈ 4 (approximated)

Answers

Answer:

y = -1

Step-by-step explanation:

1) first, you would have to substitute x, the input, with 30, y = 14-0.5(30)

2) then, you would multiply 0.5 and 30 together which gets y=14-15

3) lastly, 14-15 equals -1 so y = -1

Answer:

Answer is -1

Step-by-step explanation:

First we know that x = 30, and in 0.5x we can plug in 30 because x = 30. So the equation is 14 - 0.5(30), now multiply 0.5 * 30 which will give you 15. Now the new equation is y = 14 - 15, 14 - 15 will give you -1. And that is y, Y = -1

Han and Leila live 7 miles apart. They decide to start walking toward each other's houses at
the same time. Leila walks at a rate of 2.5 miles per hour and Han walks at a rate of 3 miles
per hour. How long will it take for them to meet?

Answers

2.5 + 3 = 5.5 total speed

7miles / 5.5 mph = 1.27 hours

Answer:

1.27 hours

Step-by-step explanation:

The first step in this process would be adding both rates of Leila and Han together. We know Leila walks at 2.5 miles per hour and Han at 3 miles per hour.

[tex]2.5 + 3 = 5.5[/tex]

We got our sum as 5.5, so now we must complete Step 2, which is the final step. We must divide 7 by 5.5.

[tex]7 / 5.5 = 1.2727...[/tex]

1.2727 ≈ 1.27

the answer to the Question is 1.27 hours.

About 1 liter of water is left in a water cooler. How much water was in the cooler when it was full

Answers

Answer:

Step-by-step explanation:

The amount of water that was in the cooler initially is dependent on the amount of water in the cooler now(that is, what is remaining). And also, the rate of which water was being used. If the rate at which water was being used was 10 liter/hour, this means that an 11 liter cooler would remain 1 liter after an hour. Because 10 liters must have been used within the said hour.

Answer:

10 liters

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

Given that A water tank is filled with a hose.

The table shows the number of gallons of water in the tank compared to the number of minutes the tank was

being filled.

The line of best for this data is g = 9m - 0.17.

We need to find when it is 45 minutes.

We have to put m value as 45 to find the number of gallons

g=9(45)-0.17

g=405-0.17

g=404.83

Hence, 405 gallons of water in the tank in 45 minutes.

A triangle has one side which is 2 meters long and another side which is 5 meters
long. Write a value that could be the length of the third side, in feet.

Answers

Answer:

23 feet > m ; or m must be less than 23 feet.

Step-by-step explanation:

Let's call this final, or third side, m.

According to the Triangle Inequality Theorem, or the Gator Theorem - as some call it - "The sum of the lengths of any two sides of a triangle is greater than the length of the third side."

So,

[tex]2+5>m\\7>m[/tex]

So, we know that m must be less than 7 meters! However, we are NOT done. We must convert M's measurement of meters into feet.

A meter is about 3.28 feet, so using that conversion...

[tex]3.28 * 7 = 22.96\\[/tex]

That is about 23 feet :)

Answer:

B. 6, 8, 14 city blocks

Step-by-step explanation:

Out of the 4 options, the distances 6 8 14 would not be an option.

What is triangle inequality?

Triangle inequality states that the sum of any two sides in a triangle is always greater than the third side.

A)5+6>9

6+9>5

5+9>6

So the triangle is possible.

B) 6+8=14 while the condition is that the sum of any two sides in a triangle is always greater than the third side i.e 6+8 must be greater than 14.

So, the triangle is not possible.

Similarly, C and D are possible triangles.

Hence, out of the 4 options, the distances 6 8 14 would not be an option.

Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldnt grow tall and produce enough food.Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers.This is crucial because crops take up phosphorus only from the soil solution.Potassium helps plants form strong stems and fast growth. It also increases disease resistance.It triggers activation of enzymes and is essential for production of ATP. Magnesium is the central core of the chlorophyll molecule in the plants tissue.
