which exponential function is represented by the table

The system of equations represented by the graph is the one in option b.

We can see that the graph is:

A solid line with a positive slope, such that the region above the line is shaded.

This is represented by:

y ≥ line.

And we can see a horizontal line at y = 4, the line is dashed and the region below the line is shaded, then we have:

y < 4

Then the system is of the form:

y ≥ line.

y < 4

The only option that has that form is option B, so that is the correct one.

Hence, the correct answer is (c)$1,055.10

Simple interest is interest calculated on the principal portion of a loan or the original contribution to a savings account. Simple interest does not compound, meaning that an account holder will only gain interest on the principal, and a borrower will never have to pay interest on interest already accrued.

We have,

Amount spent each month = $83.42

Interest rate, r = 1.8% = 0.018

Time, n = 3 years

Now,

The total amount collected at the end of the year = $83.42 × 12 = $1001.04

The value of the amount deposited in the bank after 3 years will be

Future value = Present value × ( 1 + r )ⁿ

on substituting the respective values,

we have

Future value = $1001.04 × ( 1 + 0.018 )³

or

Future value = $1,056.07

Hence,

The money he could have at the end of 3 more years will be $1,055.17

Answer:

7/12 or 0.5833

Step-by-step explanation:

So you're going to have 36 combinations, because for each number 1-6 which may be rolled for the first roll, you're going to also have 6 other possible numbers for the second roll. This gives you 6 * 6 or 36. So you could define the entire sample space, but you could also just list the sample space with all the sums less than 7 that way you don't have to list all of the sample space, since you already know how many combinations there are going to be

Let's start with the case that you roll a 1, for the first roll:

1+1 = 2

1+2 = 3

1+3=4

1+4=5

1+5=6

These are the only combinations that will be less than 7 so stop here

Now do the case where you roll a 2, for the first roll

2+1 = 3

2+2= 4

2+3 = 5

2+4 = 6

The next roll will result in a roll greater than 6. This time there were only 4 combinations which is one less than the previous. This makes sense, since you're still increasing in intervals of 1, except the starting number is increasing by 1, meaning as the first roll increases, the amount of combinations with that starting roll that are below 7, will decrease by 1. So this means that:

1: 5 combinations

2: 4 combinations

3: 3 combinations

4: 2 combinations

5: 1 combination

6: 0 combination

This means there are going to be a total of 15 combinations which are less than 7, that means there are 36-15 combinations which are greater than or equal to 7. This simplifies to 21/36 which simplifies to 7/12. This can also be expressed as: 0.5833

In a simulation, a moving object accelerates from rest to 4 meters per second in 2 seconds. For the following three seconds, it increases linearly until it reaches a speed of 10 meters per second. Following three seconds at that speed (acceleration = 0), the item progressively decelerates until it comes to rest two seconds later. Draw the graph of this scenario for 10 seconds?

I'll describe how the graph may show.

It will move diagonally upward from time 0 to 2 seconds until it reaches the y axis at a speed of 4 m/s.

Then, from 2 to 5, the position will move up diagonally until it reaches the y axis at a speed of 10 m/s.

The next 5 to 8 seconds will be horizontal.

After that, it will descend diagonally.

The true statement is the value of f(2) is larger than the value of f(3).

The function is given as:

f(x) = −3x^2 + 4x + 6

Calculate f(2) and f(3), as follows:

f(2) = −3(2)^2 + 4(2) + 6 = 2

f(3) = −3(3)^2 + 4(3) + 6 = -9

By comparison;

f(2) is greater than f(3) because 2 > 9

Hence, the true statement is the value of f(2) is larger than the value of f(3).

The graph of f(x) has been reflected across the y-axis and stretched by a factor of 2 ,  Option E is the correct answer.

A function is a law that relates a dependent and an independent variable.

It is given that f(x) = x³

g(x) = -2x³

When a function is reflected along an axis , the coordinate of that axis remains the same but the coordinate of the other axis becomes negative

So, if x coordinate is transformed to -ve of the parent function , The function is reflected along y axis.

As there is 2 in front of the parent function ,

f'(x) = a f(x) , represents vertical stretch when a >1

Therefore The graph of f(x) has been reflected across the y-axis and stretched by a factor of 2 , Option E is the correct answer.

Answer:

y = 4x + 11

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 4x - 2 ← is in slope- intercept form

with slope m = 4

• Parallel lines have equal slopes , then

y = 4x + c ← is the partial equation

to find c substitute (- 2, 3 ) into the partial equation

3 = - 8 + c ⇒ c = 3 + 8 = 11

y = 4x + 11 ← equation of line

Step-by-step explanation:

it is not clear - is 500 miles the whole round trip, or is it only the trip in one direction ?

and do we need the time for the whole round trip, or only for the return trip ?

in any case, always remember,

speed = distance/time

therefore, to get time, we need to divide distance by speed :

distance / distance/time = time×distance/distance = time

so, let's calculate all these different scenarios :

1. 500 miles is only one direction, and we measure only the time going back with 60 mph :

500 / 60 = 50/6 = 25/3 = 8 1/3 = 8 hours 20 minutes.

as 1/3 of 1 hour = 1/3 of 60 minutes = 60/3 = 20 minutes.

2. 500 miles is only one direction (going 1000 miles altogether), and we measure the time going to with 50 mph and going back with 60 mph :

500 / 50 = 10 hours

500 / 60 = 8 hours 20 minutes

the whole round trip takes 18 hours 20 minutes.

3. 500 miles is the whole round trip. so, 250 miles is one direction. and we measure only the time going back with 60 mph :

250 / 60 = 25/6 = 4 1/6 = 4 hours 10 minutes.

as 1/6 of 1 hour = 1/6 of 60 minutes = 60/6 = 10 minutes.

4. 500 miles is the whole round trip. so, 250 miles is one direction. and we measure the time going to with 50 mph and back with 60 mph :

250 / 50 = 5 hours

250 / 60 = 4 hours 10 minutes

the whole round trip takes 9 hours 10 minutes.

did you notice ?

when going only half the distance, also the time it takes to travel that distance is only half (or vice versa - double). because the ratio distance/time is always the same.

Answer:

1/9m. just take 2/9- 1/9 then you'll get the material remaining good day.

Using the concept of subtraction of fractions, Jillian have 1/9m of cloth left.

Fractions are a way to represent numbers that are not whole numbers. They represent parts of a whole or divisions of a quantity. A fraction consists of two parts: a numerator and a denominator.

The numerator is the number on the top of the fraction and represents the number of parts being considered or counted. The denominator is the number on the bottom of the fraction and represents the total number of equal parts into which the whole is divided.

In this problem, we can easily determine the amount of cloth she have left.

Since she used 1/9 of it, we can proceed as;
