The limit exists and is equal to 6.

The limit exists and is equal to 4.

Now, let's use this concept to evaluate the limits of the given function F(x). Looking at the graph of F(x), we see that it approaches different values as x approaches different points. We will evaluate each limit separately:

lim F(x) as x → 1

As x approaches 1 from the left side, the function appears to be approaching a value of 2. Similarly, as x approaches 1 from the right side, the function appears to be approaching a value of 4. However, the limit does not exist as the function is not approaching a single value as x approaches 1.

lim F(x) as x → 3

As x approaches 3, the function appears to be approaching a value of 4.

lim F(x) as x → ∞

As x approaches infinity, the function appears to be approaching a value of 6.

By using the substitution method, the value for (x,y) = (-2, 2)

The substitution method for solving a system of algebra equations is a process where by we make a variable (say variable x) the subject of the formula and substitute it into the second equation to solve for the other variable.

In essence, from the given system of equations; let's make x the subject of the formula in the first equation.

5x + 3y = -4

5x = -4 - 3y

Divide both sides by 5;

x = -4/5 - 3y/5

Now, we are going to substitute this value for x into the second equation. The second equation says:

y - 2x = 6

y - 2(-4/5 - (3y/5)) = 6

By solving for y;

y = 2

Now, let's replace the value of y with any of the given equation (2);

y - 2x = 6

2 - 2x = 6

-2x = 6 - 2

-2x = 4

Divide both sides by -2

-2x/-2 = 4/ -2

x = -2

Therefore, we can conclude that by using the substitution method, the value for (x,y) = (-2, 2)

(c) The graduates had the greater median number of hours.

(a) The range is the difference between the maximum and minimum values in a set of data. We are given the following data:

Graduates: 9641 hours, 6655432 hours, 93310 hours, and 92501 hours

Non-graduates: 2138 hours, 3 hours, 4 hours, and 13445559 hours

The range for the graduates is 9641 - 92501 = 86760 hours.

The range for the non-graduates is 2138 - 13445559 = 13443421 hours.

The value c = -2.07 for a standard normal distribution with P(z < c) = 0.0234.

To find the value of c for which P(z < c) = 0.0234 for a standard normal distribution, we can use a standard normal distribution table or a calculator with a built-in normal distribution function.

Using a standard normal distribution table, we can look up the area to the left of c and find the corresponding z-score. This z-score will be the value of c for which P(z < c) = 0.0234.

Looking up the area 0.0234 in the table, we find that the corresponding z-score is approximately -2.07.

Therefore, c = -2.07 for a standard normal distribution with P(z < c) = 0.0234.

The area of the shaded region is equal to 12.5π or 39.27 square centimeters.

In Mathematics and Geometry, the area of a semicircle can be calculated by using this formula:

Area of semicircle, As = πr²/2

Where:

r represents the radius of a circle.

Note: Radius = diameter/2 = 20/2 = 10 centimeters.

By substituting the radius into the formula for the area of a semicircle, we have the following;

Area of semicircle = 1/2 × π × 10²

Area of semicircle = 50π square centimeters.

For the circle, we have:

Area of circle, Ac = πr²

Area of circle, Ac = π(10/2)²

Area of circle, Ac = 25π square centimeters.

Now, we can determine the area of the shaded region as follows;

Area of shaded region = (As - Ac)/2

Area of shaded region = (50π - 25π)/2

Area of shaded region = 12.5π or 39.27 square centimeters.

Answer: B

Step-by-step explanation:

First, you have to know that a straight line is equal to 180 degrees. They gave you 115 degrees in part of a line, so the other part or the angle not given must be equal to 65 degrees. Another thing is that a triangle has 180 degrees. 65+80 degrees is equal to 145 degrees, leaving angle 1 to be equal to 35 degrees. Another thing to know is that reflective angles have the same measurement. If the original angle was equal to 65 after subtraction 115 from 180, we know that the second triangle's angle would also be equal to 65. 65+86 is 150, and 180-150 is 30. Thus, the answer is B.

Comparing the equations of the two lines, we can see that they have the same slope (3/2). Therefore, the lines are parallel.

To determine whether these two lines are parallel or perpendicular, we can convert Line 2 into slope-intercept form (y = mx + b):

2y = 3x + 5

y = (3/2)x + 5/2

Comparing this equation to the equation of Line 1 (y = x + 7), we see that the slopes (coefficients of x) of the two lines are not equal, nor are they negative reciprocals of each other. Therefore, the lines are neither parallel nor perpendicular.

Line 1 and Line 3:

To determine whether these two lines are parallel or perpendicular, we can convert Line 3 into slope-intercept form (y = mx + b):

6x - 4y = 4

-4y = -6x + 4

y = (3/2)x - 1

Comparing this equation to the equation of Line 1 (y = x + 7), we see that the slopes of the two lines are not equal, nor are they negative reciprocals of each other. Therefore, the lines are neither parallel nor perpendicular.

Answer:

Faster cyclist = 37.5km/h

Slower cyclist = 32.5km/h

Step-by-step explanation:

Let's call the rate of the slower cyclist "r" (in km/h). Then the rate of the faster cyclist is "r+5" (in km/h), since they are traveling 5 km/h faster.

We know that the two cyclists are traveling towards each other and will meet in 2 hours. We can use the formula:

distance = rate × time

Let's call the distance each cyclist travels "d". Since they are traveling towards each other, their distances will add up to the total distance between the two towns, which is 130 km. So we can write:

d + d = 130

2d = 130

d = 65

Now we can use the formula again to find the rates of the two cyclists:

For the slower cyclist:

distance = rate × time

65 = r × 2

r = 32.5 km/h

For the faster cyclist:

distance = rate × time

65 = (r+5) × 2

r+5 = 32.5 + 5 = 37.5 km/h

So the rate of the slower cyclist is 32.5 km/h, and the rate of the faster cyclist is 37.5 km/h.

Answer:

0.90

Step-by-step explanation:

Just like a decimal to a percentage number, you must multiply by 100. By converting a percentage number to a decimal point, you must divide it by 100. Which means, the decimal must move 2 times.

For example,

0.90 x 100 = 90%

This is decimal to percentage number, but in this case it is percentage to decimal.

90%.

Since the number ended at 0, put the decimal there and move it 2 times to get to your decimal point.

.90 = 0.90
