How to tell if your table is linear or exponential?

Answers

Answer: If the first difference is the same value, the model will be linear. If the second difference is the same value, the model will be quadratic. If the number of times the difference has been taken before finding repeated values exceeds five, the model may be exponential or some other special equation.

Step-by-step explanation: You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear.

Step-by-step explanation:

Prompt: A car is traveling down a highway at the constant speed, described by the equation “d=65t” , where “d” represents the distance, in miles, that the car travels at this speed in “t” hours.

Question 1:
1. What does 65 tell us in this situation?

a. The car travels 65 miles in 1 hour.
b. The constant of proportionality is 65 miles per hour.
c. The car traveled a total of 65 miles
d. The car is traveling 65 miles per hour.

—————————————————————

Question 2:
2. How many miles does the car travel in 1.5 hours?

The car travels □ miles in 1.5 hours.

Please Help!

Answers

Answer:

1) d

2) 97.5 miles

3)I am unsure on

Step-by-step explanation:

1) d=65t means that it is moving 65 miles per that amount of time (in this case using mph)

2) you take your equation "d=65t" and fill in your time (1.5) 65(1.5)=97.5

Answers

Answer:

Option B: If two lines are parallel, then alternate interior angles are

congruent.

Step-by-step explanation:

Notice that angles 3 and 6 are INTERNAL relative to the parallel lines, that is located in between the parallel lines. They are also alternate angles. Therefore, the correct answer is:

"If two lines are parallel, then alternate interior angles are  congruent."

A farmer with 5000 feet of fencing wants to enclose a rectangular field and then divide it into two plots by adding a fence in the middle parallel to one of the sides. Using the function A(x) , analytically find the WIDTH of the field that would maximize its area. (Round your answer to the nearest whole number)

Answers

Answer:

The required width of the field that would maximize the area is = 1250  feet

Step-by-step explanation:

Given that:

The total fencing length = 5000 ft

Let consider w to be the width and L to be the length.

Then; the perimeter of the rectangular field by assuming a parallel direction is:

P = 3L + 2w

⇒ 3L + 2w = 5000

3L = 5000 - 2w

[tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex]

Recall that:

The area of the rectangle = L×w

[tex]A(w) = ( \dfrac{5000}{3}-\dfrac{2}{3} ) w[/tex]

[tex]A(w) = \dfrac{5000}{3}w-\dfrac{2}{3} w^2[/tex]

Taking the differentiation of both sides with respect to t; we have:

[tex]A' (w) = \dfrac{5000}{3} - \dfrac{2}{3} ( 2 w)[/tex]

[tex]A' (w) = \dfrac{5000}{3} - \dfrac{4w}{3}[/tex]

Then; we set A'(w) to be equal to zero;

So; [tex]\dfrac{5000}{3} - \dfrac{4w}{3}=0[/tex]

5000  = 4w

w = 5000/4

w = 1250

Thus; the required width of the field that would maximize the area is = 1250  feet

Also, the length [tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex] can now be :

[tex]L = \dfrac{5000}{3} - \dfrac{2(1250)}{3}[/tex]

L = (5000 -2500)/3

L = 2500/3 feet

Suppose, the farmer divides the plot parallel to the width; Then  2500/3 feet = 833.33 feet and the length L = 1250 feet.

A line passes through the point (8,4) and has a slope of -3/4 Write an equation in slope-intercept form for this line.​

Answers

Step-by-step explanation:

Hey there!

Given;

The line passed through point (8,4) and made slope (-3/4).

Note: Use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

Put all values.

[tex](y - 4) = \frac{ - 3}{4} (x - 8)[/tex]

[tex]y - 4 = - \frac{3}{4} x - \frac{3}{4} \times - 8[/tex]

[tex]y - 4 = - \frac{3}{4} x + 6[/tex]

[tex]y = - \frac{3}{4} x + 6 + 4[/tex]

Therefore, the equation is: y = -3/4x +10.

9. Which point of view is most likely to be uni eliable in a story?
All points of view in a story are equally eliable.
The first person narrator is most likely to be unreliable.
All points of view in a story are equally unreliable.
The third person point of view is most likely to be unreliable.

Answers

This question includes some misspelled words; here is the correct question:

Which point of view is most likely to be unreliable in a story?

All points of view in a story are equally reliable.

The first person narrator is most likely to be unreliable.

All points of view in a story are equally unreliable.

The third-person point of view is most likely to be unreliable.

The correct answer is The first-person narrator is most likely to be unreliable.

Explanation:

In a narrative text, an unreliable narrator implies the narrator lies on purpose to the reader, or his/her version of the story is not completely accurate. This feature of narration occurs mainly if the story, novel, etc. includes a first-person narrator. This is because in a first-person narrator, the thoughts, feelings, and point of view of one of the characters prevail, and this causes the events told are subjective and therefore more likely to be inaccurate. Also, this does not occur if there is a third-person narrator because in this case the narrator acts as an observer and this makes it more objective.

A train traveled from one city to another city in 4 hours at a speed of 70 mph.
The retum trip was made in 5 hours. Find the speed for the return trip.

Answers

Answer:

56miles/hr

Step-by-step explanation:

Given parameters:

Time taken for the to travel  = 4hrs

Speed of the train  = 70mph

  From this data, let us find the distance of the trip;

Distance  =Speed x time

  Therefore, insert the parameters;

          Distance  = 70mph x 4hr = 280miles

Now;

  Return trip took, 5hrs,

Speed  = ?

  Speed  = [tex]\frac{distance}{time}[/tex]  

Insert the parameters and solve;

     Speed  = [tex]\frac{280}{5}[/tex]   = 56miles/hr
