From the given linear function, it is found that each descent by 88 meters was 11 seconds long.

The graph of the linear function is missing, and it is given at the end of the answer.

A linear function is modeled by:

y = mx + b

In which:

Given two points on the graph, the slope is given by change in y divided by change in x. For this problem, the points are given as follows:

(0, 440) and (40,0).

Hence the slope is:

m = (0 - 440)/(40 - 0) = -11.

Meaning that in each minute, he descended 8 meters. Thus the time to descend 88 meters is given by:

t = 88/8 = 11 seconds.

Each descent by 88 meters was 11 seconds long.

The approximate length of string lights the staff needs to decorate the ceiling is 40.25

The complete question is added as an attachment

From the attached figure, we have the following coordinates

A = (5, 16)

B = (17, 10)

C = (14, 4)

D = (2, 10)

Calculate the lengths AB and BC using the following distance formula

d = √[(x2 - x1)^2 + (y2 - y1)^2]

This gives

AB = √[(5- 17)^2 + (16- 10)^2] = 13.4

BC = √[(14- 17)^2 + (4- 10)^2] = 6.7

The approximate length of string lights the staff needs to decorate the ceiling is then calculated as

P = 2 * (AB + BC)

This gives

P = 2 * (13.4 + 6.7)

Evaluate

P = 40.2

Hence, the approximate length of string lights the staff needs to decorate the ceiling is 40.25

Answer:

y = -1/12x + 11

Step-by-step explanation:

An ordered pair is the form (x,y)  Us the x and y from the point and the slope to find the y intercept and then you can write the equation.

Use o for x and  11 and or y and - 1/12 for m

y = mx + b

11  = (-1/12)(0) + b

11 = b

y = -1/12x + 11

Answer:

Y = -1/12 x + 11

Step-by-step explanation:

Start with point (0,11)   slope ( -1/12)  form :

(y-11) = -1/12 (x-0)

      re-arrange to slope intercept form just by adding 11 to both sides

y = -1/12 x + 11    

Two numbers are drawn without replacement. The only way their product is zero is if one of these numbers is zero. The probability of this happening is

[tex]\dfrac{\dbinom11 \dbinom51}{\dbinom62} = \dfrac{1\cdot5}{15} = \boxed{\dfrac13}[/tex]

In other words,

• there is 1 zero in the list - we draw it with [tex]\binom11 = 1[/tex] way of doing so;

• there are 5 non-zero numbers in the list - we draw 1 of these, with [tex]\binom51 = 5[/tex] ways of doing so;

• there is a total of 6 numbers in the list - we draw 2 of these, with [tex]\binom62 = 15[/tex] ways of doing so.

On the other hand, if the numbers are drawn with replacement and independently of one another, then each number has the same probability of getting drawn each time. There are 6×6 = 36 possible outcomes, each with 1/36 probability of occurring. Their product is zero if at least one of the numbers drawn is zero. The probability of this happening is

[tex]\dbinom21 \dfrac16 \times \dfrac56 + \dbinom22 \left(\dfrac16\right)^2 = \dfrac{11}{36}[/tex]

That is,

• there is 1/6 chance of drawing a zero and 5/6 chance of not drawing a zero. This can selection can happen in [tex]\binom21=2[/tex] ways (zero is drawn first or last);

• there is 1/6 chance of drawing a zero for either selection. This can happen in [tex]\dbinom22=1[/tex] way (zero is drawn both times).

While the probabilities are close, they are not the same! Be careful with which interpretation you choose.

Yes, the pole will fit in the box when kept diagonally.

In order to fit the pole in rectangular prism or cuboid, it has to be kept diagonally. Now, we need to calculate the length of body diagonal of cuboid. The length of body diagonal of cuboid should be greater than pole to fit it.

The length of body diagonal of cuboid can be calculated by the formula -

Diagonal = √(l² + b² + h²)

Keep the values in formula to find the diagonal of rectangular prism

Diagonal = √(10² + 9² + 8²)

Taking square of the three numbers to find the diagonal of rectangular prism

Diagonal = √100 + 81 + 64

Taking sum of numbers present on Right Hand Side of the equation

Diagonal = √245

Taking square root of the number

Diagonal = 15.65 feet

Hence, as the diagonal of rectangular prism is greater than shower curtain pole, it will definitely fit.

A rectangle may be a form of quadrilateral, whose opposite sides are equal and parallel.

From the given information:

the length of a rectangle is fourfold its width. if the perimeter is at the most 106 centimeters

Then

L = 4w --------The length of a rectangle is fourfold its width.

2w + 2L ≤ 106 ------- the perimeter is at the most 130 centimeters.

Now, if substitute the primary equation into the second inequality you may get

2w + 2 • (4w) ≤ 106.

Therefore, the inequality model becomes 2w + 2 • (4w) ≤ 106.

The ratio between Miles and Hours is 5:4

In the table, miles = 40 is got by 8 x 5 = 40

So corresponding hours = 8 x 4 = 32

In the table, hours = 36 is got by 9 x 4 = 36

So corresponding miles = 9 x 5 = 45

So the ratios are 5:4 , 40:32, 45:36

Graph can be plotted with number of miles in the x-axis and number of hours in y-axis.

k=-14/3

Average = -14/3

Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.

The average rate of change is a measure of how quickly on average one quantity changes in relation to another. It provides a general sense of the function's change in value per unit throughout the specified time period. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another. Let's take a closer look at the average rate of change formula.

Answer:

  11)  KI = 28

  12) PR = 22

Step-by-step explanation:

You want the base segment lengths KI and PR, given relations between those segments and the corresponding midsegment of the triangle.

A midsegment is a line segment that joins midpoints of other line segments, usually the midpoints of triangle sides or opposite sides of a quadrilateral. In the case of a triangle, the midsegment is parallel to the third side, and half its length. This relation is used to solve these problems.

  KI = 2·AB

  (x +37) = 2(x +23) . . . . substitute given expressions

  x +37 = 2x +46 . . . . . . eliminate parentheses

  37 = x +46 . . . . . . . . . . subtract x

  28 = x +37 . . . . . . . . . . subtract 9

The length of KI is 28 units.

  PR = 2·HG

  (x +30) = 2(19 +x) . . . . substitute given expressions

  x +30 = 38 +2x . . . . . eliminate parentheses

The length of PR is 22 units.

Additional comment

As you can see here, there is no real reason to find the value of x, then substitute it back into the expression for the segment of interest. We can, and did, solve directly for the value of that expression.

As with any algebraic manipulation, any operation performed on one side of the equal sign must also be performed on the other side of the equal sign. When we say "subtract ()", we mean "subtract () from both sides of the equation."

In problem 11, x=-9. In problem 12, x=-8. Negative values of x work just fine, as long as the resulting segment lengths are positive.

n(D ∪ C) = n(D) + n(C) - n(D ∩ C)

Then,

Total = n(D ∪ C) + 24

Total = 22 + 24

Using the motion equation we can get:

a) s = -16*t^2 + 1028

b) 992 feet above the ground.

c) after 8 seconds, the coin will hit the ground.

First, we know that the general height equation is:

s = -16*t^2 + v0*t + s0

In this case, the coin is dropped, so the initial velocity v0 is zero.

And the coin is dropped from a height of 1028 ft, then s0 = 1028

Replacing that in the equation we get:

s = -16*t^2 + 1028

b) The height after 1.5 seconds is what we get by evaluating the height equation in t = 1.5

s = -16*(1.5)^2 + 1028 = 992

This means that the height after 1.5 seconds is 992 ft above the ground.

c) The coin will strike the ground when s = 0, then we need to solve:

s = 0 = -16*(t)^2 + 1028

Solving that for t, w eget:

16*t^2 = 1028

t^2 = 1028/16

t = √(1028/16) = 8

This means that the coin will hit the ground after 8 seconds.
