You take the difference between any two y and divide by the difference in the corresponding x. The number should be the same always for a straight line. That's your slope. A fancy way of writing it is dy/dx

so: (10-2)/(3-1) = 8/2 = 4 (using the first two points)
or: (26-2)/(7-1) = 24/6 = 4 (using the first and the last)

Value​ rent-a-car rental a luxury car at a daily rate of ​$43.09 plus 4 cents per mile. a business person is allotted ​$100 for car rental each day. how many miles can the business person travel on the ​$100

Answers

To calculate the total miles he is allowed we must setup an expression for total cost of the car per day. Cost = 43.09 + .04x where x is the number of miles driven. To find out the number of miles driven with $100, we plug in $100 for cost and solve for x. Doing this we get 100 = 43.09 + .04x, where .04x = 56.91 and solving for x we get x=1422.75 or 1422 miles. In this case we do not round up since adding an additional mile would put us over the $100 budget. Answer = 1422 miles.

G(a)=2a-1 h(a)=3a-3
Find (g-h)(-4)

Answers

Final answer:

To find (g-h)(-4), we calculate g(-4) as -9 and h(-4) as -15. Subtracting the latter from the former results in -9 + 15, which equals 6.

Explanation:

To find (g-h)(-4), we need to calculate the value of g at -4 and the value of h at -4, and then subtract the value of h from g.

The functions are defined as G(a)=2a-1 and h(a)=3a-3. Let's compute these step-by-step:

Calculate g(-4):

G(-4) = 2(-4) - 1

= -8 - 1

= -9

Calculate h(-4):

h(-4) = 3(-4) - 3

= -12 - 3

= -15

Calculate (g-h)(-4):

= g(-4) - h(-4)

= -9 - (-15)

= -9 + 15

= 6

Therefore, (g-h)(-4) equals 6.

One angle in a triangle measures twice the smallest angle, whereas the largest angle is nine times the smallest angle. find the measures of all three angles.

Answers

The measures of all three angles are 15, 30, and 135 degrees respectively.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Let the smallest angle be represented as x,

one angle = 2x

largest angle = 9x

Therefore, x + 2x + 9x = 180° (by angles sum in a triangle)

12x = 180°

x = 15°

Then 2x = 15° x 2

= 30°

Also, 9x = 15° x 9

= 135°

Hence, The smallest angle is 15° and the one angle is 30°.

The largest angle is 135°.

1996 gail devers won the 100-meter dash in the olympic games. her times was 10.94 seconds. what was her speed in meters per second?

Answers

Solving this problem is just pretty straight forward. We simply have to get the ratio of distance and time to get the speed. that is:

speed = distance / time

speed = 100 m / 10.94 s

speed = 9.14 m/s

Final answer:

Gail Devers' average speed during her Olympic win in the 100-meter dash with a time of 10.94 seconds is calculated to be approximately 9.14 meters per second using the formula speed = distance/time.

Explanation:

In 1996, Gail Devers won the 100-meter dash in the Olympic Games with a time of 10.94 seconds. To find her average speed in meters per second, we use the formula:

s = d / t

where s is speed, d is distance, and t is time. Given that the distance (d) is 100 meters and the time (t) is 10.94 seconds, we can calculate the average speed:

s = 100 m / 10.94 s ≈ 9.14 m/s

Therefore, Gail Devers' average speed during her Olympic 100-meter dash victory was approximately 9.14 meters per second.

How to calculate percentage increase

Answers

Work out the difference (increase) between the two numbers you are comparing. Then divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.
Final answer:

A percentage increase can be calculated by first finding the difference between the new and original values, then dividing that difference by the original value. The result is then multiplied by 100 to get the percentage increase. This method can also help calculate inflation rates and various other mathematical problems.

Explanation:

To calculate a percentage increase, you need to understand the basic principles of mathematics. Using the context provided, we can define calculating a percentage increase in the following way:

Steps to Calculate Percentage Increase:        

For example, suppose the original price for a basket of goods was $20 and the new price is $25. First, find the difference: $25-$20 = $5. This is the increase. Then, divide the increase ($5) by the original price ($20) to get 0.25. Multiply by 100 and you get a 25% increase.

This method can be applied to many scenarios including calculating the rate of inflation. There are also online calculators and computers that can assist in finding these percentages quickly.

2. The point (1,0) lies on the graph of p(x)=x^4-2x^3-x+2
True or false

Answers

Answer:

1. Option B is the correct answer.

2. The point (1,0) lies on the graph of p(x)=x⁴-2x³-x+2.

Step-by-step explanation:

1. Dividing x³-7x²+15x-9 with (x-1).

      [tex]\frac{x^3-7x^2+15x-9}{x-1}=x^2-6x+9[/tex]

  Factorizing x²-6x+9 we will get

       x²-6x+9 = (x - 3)(x-3)

  x³-7x²+15x-9 = (x-1)(x - 3)(x-3)

  Option B is the correct answer.

2. We have p(x)=x⁴-2x³-x+2

   That is y = x⁴-2x³-x+2

   We have coordinates (1,0), substituting

   y = 1⁴-2 x 1³-1+2 = 0

   So when we are substituting x value as 1 we are getting y as zero, so the point lies in curve.

A golf ball is dropped from a height of 30 ft to the pavement, and the rebound is one fourth the distance it drops. if after each descent it continues to rebound one fourth the distance dropped, what is the distance the ball has traveled when it reaches the pavement on its tenth descent?

Answers

Final answer:

The question deals with a sequence of movements of a golf ball falling and rebounding, which forms a geometric series. To find the total distance traveled by the ball on its 10th descent, we calculate the sum of the first 19 terms of this geometric progression.

Explanation:

The student is asking about a geometric series problem, which involves a golf ball being dropped from a height and rebounding to a fraction of that height. The sequence of the distances covered by the ball forms a geometric progression.

Let's denote the initial height the ball is dropped from as a, which is 30 ft. The rebound height is one-fourth of the descent, so the rebound ratio, or common ratio r, is 1/4. The ball travels the initial height a plus the rebound distance each time it hits the pavement. This series continues with each rebound being one-fourth of the previous fall. We want to find the total distance traveled by the ball as it hits the pavement on its 10th descent.

The total distance traveled D after the ball hits the pavement for the 10th time is the sum of the first 10 terms of this geometric sequence. Using the formula for the sum of the first n terms of a geometric series, [tex]S_n = a(1-r^n)/(1-r)[/tex], where n is the number of terms, we can calculate the total distance.

For 10 descents, we have n = 19 since each descent and rebound except

the last descent counts as two movements:
[tex]S_{19} = 30(1-(1/4)^{19})/(1-(1/4))[/tex]
[tex]S_{19} = 30(1-(1/4)^{19})/(3/4)[/tex]
By calculating [tex]S_{19[/tex], we find the total distance traveled when the ball hits the pavement on its 10th descent.

Point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.)

Answers

Answer:  The required distance between the two points R and T is 1.1 units.

Step-by-step explanation:  Given that point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid.

We are to find the distance between the two points R and T.

Distance formula :

The distance between the two points A(a, b) and B(c, d) is given by

[tex]d=\sqrt{(c-a)^2+(d-b)^2}.[/tex]

Therefore, the distance between the points R and T is given by

[tex]d=\sqrt{(3-3)^2+(2.4-1.3)^2}=\sqrt{0^2+1.1^2}=\sqrt{1.1^2}=1.1.[/tex]

Thus, the required distance between the two points R and T is 1.1 units.

The distance is 1.1 units, which is the distance between point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid.

What is a distance formula?

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

We have two points such that:

R (3, 1.3) and T (3, 2.4)

The distance formula for finding the distance between two points is:

If the points are [tex]\rm (x_1, y_1) \ \ and \ \ (x_2, y_2)[/tex]

[tex]\rm D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here:

[tex]\rm x_1= 3\\\rm y_1= 1.3\\\rm x_2= 3\\\rm y_2= 2.4\\[/tex]

Then,

[tex]\rm D = \sqrt{(3-3)^2+(2.4-1.3)^2}[/tex]

[tex]\rm D = \sqrt{(1.1)^2}[/tex]

D = √1.21

D = 1.1 units

Thus, the distance is 1.1 units, which is the distance between point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid.
