S see Use the graph y=e^x to evaluate these expression e^0
nika2105 [10]

Answer:

y= e^x

And we want to evaluate e^0 using the graph

And as we can see in the plot the y intercept is the blue point with y=0 and that correspond with:

y(0)= e^0 =1

Step-by-step explanation:

For this problem we know the following function:

y= e^x

And we want to evaluate e^0 using the graph

And as we can see in the plot the y intercept is the blue point with y=0 and that correspond with:

y(0)= e^0 =1

The table shows the height of a plant as it grows. Which equation in point ­slope form gives the plant’s height at any time
vodka [1.7K]

Answer:

Option A is correct.

y-16=8(x-2) is the equation represent the point slope form gives the plant's height at any time.

Step-by-step explanation:

Point slope intercept form: For any two points (x_1, y_1) and  (x_2, y_2) then,

the general form

y-y_1=m(x-x_1) for linear equations;  where m is the slope given by:

m =\frac{y_2-y_1}{x_2-x_1}

Consider any two points from the table;

let A= (2 , 16) and B =(4, 32)

First calculate the slope of the line AB:

m =\frac{y_2-y_1}{x_2-x_1}=\frac{32-16}{4-2}=\frac{16}{2} = 8

Therefore, slope of the line m = 8

Then,

the equation of line is:

y-y_1=m(x-x_1)

Substitute the value of m=8 and (2, 16) above we get;

y-16=8(x-2)

Therefore, the equation in point slope form which gives the plant's height at any time is; y-16=8(x-2) , where x is the time(months) and y is the plant height (cm)

Lola is making greeting cards, which she will sell by the box at an arts fair. She paid $50 for a booth at the fair, and the mat
Schach [20]

At some point, she will sell enough cards so that her sales cover her expenditures. So, the correct answer is ($40)

<h3> How did we figure this out?</h3>

Lola is making greeting cards, which she will sell by the box at an arts fair. She paid $50 for a booth at the fair, and the materials for each box of cards cost $8. She will sell the cards for $10 per box of cards.

We are going to use 50, 8 and 10 to find are answer.

Therefore, we are going to divide the numbers:

\boxed{50/10}

  • Division problem
  • 50/10
  • 8 x ? = 40
<h3 /><h3>What is the missing number?</h3>

First, we need to figure out 50/10:

\boxed{50/10=5}

\boxed{8x5=40}

5=40\\(50/10=5=8x5=40)

Therefore, at some point, she will sell enough cards so that her sales cover her expenditures. So, the correct answer is ($40)

Quesuon Z: 2 PES
cricket20 [7]

Answer:

124 ft2

Step-by-step explanation:

The yard is a 12ft square so the length and width would both be 12ft. You multiply the length and width of the yard to get the area of the yard so 12x12=144. You have the length and width of the flower bed so 5x4=20. Once you have the area of both you can subtract the area the flower bed takes up of the lawn. 144-20=124 ft2.
