Answer:

9.9 feet per second

Step-by-step explanation:

y=9.5+0.4

y=9.9

Marcella's average speed in feet per seconds is,

⇒ y = 9.54 feet

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,

⇒ y = 9.50x + 0.4

Hence, Marcella's average speed in feet per seconds is,

y = 9.50x + 0.4

Put x = 1;

y = 9.50 × 1 + 0.4

y = 9.50 + 0.4

y = 9.54 feet

Thus, Marcella's average speed in feet per seconds is,

⇒ y = 9.54 feet

Answer:

The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Step-by-step explanation:

Total members=13000

Membership charge per month=$7

Increase in Membership charge per month=$1

For each $1 monthly increase in membership fee, the club loses approximately=500 members

For 1 month, 1 dollar decrease is 500 × 1

For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]

The increase in membership fee is 7 + [tex]x[/tex]

After that,

Monthly revenue = Number of members × Monthly fee

Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]

[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Hope this helps and have a nice day!

Answer:The difference between the number of children and adults=153

Step-by-step explanation:

ratio of men to women to children is 1:3:20

Total RATIO = 1+ 3+ 20= 24

Number of men = ratio of men / Total ratio x  Total Number of people on the trip =

= 1/24 x 216= 9 men

Number of women=ratio of women / Total ratio x  Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women

Number of children=ratio of Children/ Total ratio x  Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children

The difference between the number of children and adults will be 180 -27 = 153

Answer: The number is 106.4

Step-by-step explanation:

Let the number be x

Mar halves the number becomes = x x 1/2  to get 53.2

The equation to solve this problem is  x/ 2 = 53.2

Such that to find x

x/2= 53.2

x =  2 x 53.2= 106.4

The number is 106.4

Answer:

a. True

b. False

c. True

d. False

e. False

Step-by-step explanation:

a. 2.3 + ( -2.3) = 0

b. (-3.7) + (-4.1) = -7.8

c. -2.6 - (-12/4) = 0.4

d. 5/2 + (-2.5) = 0

e. 72 - (-100) = 172

Answer: I’d say B Or D

Step-by-step explanation:

Answer:

[tex]y-9 = \frac{15}{7} (x-8)[/tex]

Step-by-step explanation:

Point-slope form is represented by [tex]y-y_1 = m (x-x_1)[/tex]. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.

To find the slope, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line crosses, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:

[tex]\frac{(9)-(-6)}{(8)-(1)} \\= \frac{9+6}{8-1} \\= \frac{15}{7}[/tex]

Thus, the slope is [tex]\frac{15}{7}[/tex].

2) Now, using the point-slope form of  [tex]y-y_1 = m (x-x_1)[/tex],  substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values in order to write an equation in point-slope form. The [tex]m[/tex] represents the slope, so substitute [tex]\frac{15}{7}[/tex] in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for [tex]x_1[/tex] and [tex]y_1[/tex]. (I chose (8,9)). This gives the following equation and answer:

[tex]y-9 = \frac{15}{7} (x-8)[/tex]

Do you have the whole question? The problem that you gave does not have a problem....

Answer: B -4

Step-by-step explanation:

Value of coefficient of the squared term in the parabola's equation = -4

Correct option is B.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

Given,

Vertex of parabola (h,k) = (3, 5)

y = 6 for x = -1

Parabola opens horizontally left side

Vertex-form equation of parabola

x = a(y - k)² + h

-1 = a(6 - 5)² + 3

-1 = a(1) 3

a = -4

Hence, -4 is value of coefficient of the squared term in the parabola's equation.

Answer:

most likely asking for something like this

Step-by-step explanation:

Answer:

Read the step-by-step for the entire answer!!!

Step-by-step explanation:

Whenever you have situations like these you have to look at it from the perspective given.

If you are throwing a ball it's going to start at ground 0 where the child is, therefore the height of the child is how high off the ground the ball is at 0 seconds.

If it is thrown, and it is stuck in the tree for a few seconds, then that means on the graph you will see an incline of the graph, and then a stale line for a few seconds as the ball is stuck in the same height for a few seconds.

After the ball falls down, then so will the height of the ball.

t - a function of time, is always on the x-axis because time variables are usually on the x-axis of a graph.

I choose seconds as a measurement of time because in a realistic situation a ball will be in the air for seconds.

h - the height of the ball, will be on the y-axis of the graph because it is a dependent variable (i.e. the height of the ball is dependent on how long the ball is in the air for).      

The image below is the graph.
