Step-by-step explanation:

The km/minute is different for segment, so "The train does not always go . . ."

Tha average speed in km/minute of the 3 points is 3.2km/min. 10 minutes would be 32km.

Divide the cost by the number of people. It is $7/person in each case. The cost for each person appears to be the same. If Sam knew more math, he could charge each person $10 and end the evening $3/person richer. He would need at least 3 people to cover his own expense, and have $2 left for a tip to the attentive waitress who approved his strategy for profiting from his math skills.

Step-by-step explanation:

The problem basically asks you to substitute 2 in, hence h(2).

Here is your base equation.

h(x)=-x^2+6x

Plug in 2.

h(2)=-2^2+6(2)

Simplify, using PEMDAS.

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line 4x + 3y = 12? Drag and drop each choice into the boxes to correctly complete the table. Parallel Perpendicular Neither

Answers

Step-by-step explanation:

The line given:

4x + 3y = 12, its slope is m = - 4/3

Other lines to compare:

-3x + 4y = 8, the slope is m = 3/4, it is perpendicular line as the product of the slopes is - 1;4x + 3y = 31, the slope is m = -4/3, same slope but different y- intercept, it is parallel line;3x + 4y = 12, the slope is m = -3/4, it is neither parallel nor perpendicular;-4x + 3y = - 1, the slope is m = 4/3, it is neither parallel nor perpendicular

4x+3y=123y=-4x+12y=-4/3x+12

Slope=m=+4/3

-3x+4y=8

m=3/4

Perpendicular

4x-3y=31

m=-4/3

Parallel

3x+4y=12

m=-3/4

neither

-4x+3y=-1

m=4/3

Neither

A train decreased its speed by 72 miles hour in 12 minutes. Find the average change in speed per minute.

Answers

Answer:

6 mph

Step-by-step explanation:

The average rate of change of the speed of the train will be 6 miles per hour.

What is speed?

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that a train decreased its speed by 72 miles per hour in 12 minutes.

As the train is reducing its speed by 72 miles per hour in 12 minutes the average rate of change of the speed will be calculated by dividing the change by the time.

Rate of change = 72 / 12

Rate of change = 6 miles per hour

Therefore, the average rate of change in the speed of the train will be 6 miles per hour.

Answers

Answer:

Slope = 0.667/2.000 = 0.333

x-intercept = 6/1 = 6.00000

y-intercept = 6/-3 = 2/-1 = -2.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

4*x-12*y-(24)=0

Step 1: Pulling out like terms

Pull out like factors :

4x - 12y - 24 = 4 • (x - 3y - 6)

Equation at the end of step 1:

Step 2:

Equations which are never true:

Solve : 4 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Equation of a Straight Line

Solve x-3y-6 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y-6 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 2/-1 so this line "cuts" the y axis at y=-2.00000

y-intercept = 6/-3 = 2/-1 = -2.00000

Calculate the X-Intercept :

When y = 0 the value of x is 6/1 Our line therefore "cuts" the x axis at x= 6.00000

x-intercept = 6/1 = 6.00000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -2.000 and for x=2.000, the value of y is -1.333. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.333 - (-2.000) = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 0.667/2.000 = 0.333

Geometric figure: Straight Line

Slope = 0.667/2.000 = 0.333

x-intercept = 6/1 = 6.00000

y-intercept = 6/-3 = 2/-1 = -2.00000

So we have our equation now lets plug it in

-9+2/-4-3 (we make it a plus for -9+2 because the two minuses cancel out).

So now we have -7/-7 which is 1 because -7 divided by itself is one. Thereby your answer is A. 1

Answer:

x-intercept = 2

Step-by-step explanation:

Sum = 3

Product = -10

Factors = 5 , (-2) {5*(-2) = -10 & 5 +(-2) = 3)

Rewrite the middle term using the factors: 3x = 5x - 2x

x² + 3x - 10 = x² + 5x - 2x - 10

=x(x + 5) - 2(x + 5)

= (x +5)(x - 2)

x² + 8x +15 = x² + 3x + 5x + 15

= x(x + 3) + 5(x + 3)

= (x + 3)(x + 5)

[tex]f(x) =\dfrac{x^{2}+3x -10}{x^{2}+8x + 15}\\\\=\dfrac{(x+5)(x -2)}{(x+5)(x+3)}\\\\=\dfrac{x-2}{x+3)}[/tex]

At x-intercept, y = o

Answers

Answer:

Step-by-step explanation:

Hi there!

It is possible for a line and a circle to not intersect at all.

It is also possible for a line and a circle to meet at one point only. They would be tangent to each other and touch.

Finally, it is possible for a line to intersect the circle. They would appear overlapping. In any of these cases where a line intersects a circle, they would have crossed the circle at two points.

A line and a circle can only have a total number of 2 intersection points.

Your 2 year investment of $5,300 earns 2.9% and is compounded annually. What will your total return be?

Answers

The total return will be $5611.8

How to calculate the total return?

A 2 year investment of $5,300 earns 2.9%

The investment is compounded annually

The total return can be calculated as follows

= 5300 (2.9/100 + 1)

= 5300 (0.029 + 1)

= 5300(1.029)²

= 5300(1.0588)

= $5611.8

Hence the total return is $5611.8
