In the picture there are 4 graphs.

We have to find the domain and range of the each function using inequality or set-builder notation.

A function's domain is the set of values that we are allowed to enter into our function.

This set consists of the values of the x-axis for a function like f. (x).

The range of values that can be used as input for a function is called this. The values in this set hence, once we input an x value, the function returns. The y values are those.

The distance that the person bike over the past 5 weeks is 7284 feet.

Distance is the sum of an object's movements, regardless of direction. Regardless of an object's starting or ending position, distance can be defined as the amount of ground it has covered. Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively.

From the information, the forest trail is 607 feet long and a person biked from one end to the other and back again 6 times in the past 5 weeks.

Therefore, the distance that the person covered will be:

= 2 × 6 × 607

= 7284 feet.

The distance is 7284 feet.

The circumference of the circle will be given by 62.84 cm.

A circle is a closed figure having a fixed point known as center of the circle and the distance from the center to any point on the boundary of circle is known as the radius of the circle. Circumference is the total length of the boundary of the circle. The circumference of the circle is given by the formula

C = 2πr where r is the radius of the circle and the value of π is given as 3.142.

Now, according to question r = 10cm

C = 2×3.142×10

After using translation the image of the given points will be at Q( 6 , 6 ) and  M( -2 , -11 ).

What is translation ?

The linear movement of a point relative to its initial position is known as translation. The horizontal position is labeled first and the vertical position is labeled second when describing a point's coordinates with respect to the origin of an x-y coordinate plane.

The translation is given to be (x,y) → (x + 1, y - 3)

The tow points are Q(5,9), M(-3,-8)

using translation  we get,

Q( 5 , 9 ) → (5 + 1, 9 - 3) = Q( 6 , 6 )

M( -3 , -8 ) → (-3+ 1, -8- 3) = M( -2 , -11 )

3 x 12 = 36

Then you should do 43.56 / 36

For one pair of gloves it should be $1.21

The contractor got $14.52 because he did a dozen (12) divided by 43.56.

Answer:

Step-by-step explanation:

Sorry if this is incorrect

The hang time is calculated to be a. 1.5 seconds if the vertical component of velocity for the projectile is 7.3 meters/second.

The formula for the height of the projectile can be used to calculate the hang time as follows;

h = ut - 0.5at²

here;

h is the height of the projectile

u is the velocity = 7.3 m/s

a is the acceleration due to gravity

The standard value of acceleration due to gravity is equal to 9.81 m/s²

The height will be zero both the times when t=0 and when the journey has been completed

Now adding these values to the formula;

h = ut - 0.5at²

0 = 7.3t - 0.5(9.81)t²

Solving for t;

4.905t² = 7.3t

4.905t² / t = 7.3

4.905t = 7.3

t = 7.3 / 4.905

t = 1.49 ≈ 1.5

Therefore; the hang time is calculated to be 1.5 seconds.

Step-by-step explanation:

99.87-71 = 28.81     this is   28.81/12 = z-score = +2.4

   corresponding to .9918  ( from z-score table)  =  a score of 99.18%

The coordinates of the point X are (1 + 2, 6 - 1.25) = (3,4.75).

The segments, PX and XQ, have lengths in a ratio of 1: 2.

A line segment is partitioned when it is divided into equal parts according to a specified ratio. The total number of partitions of the line segment must be equal to the sum of the two values in the ratio.

Suppose you have a line segment PQ on the coordinate plane, and you need to estimate the point on the segment 1/3 of the way from P to Q.

Where P exists at the origin and line segment is a horizontal one.

The length of the line exists 6 units and the point on the segment 1/3 of the way from P to Q would be 2 units away from P, 4 units away from Q and would be at (2, 0).

The segment exists not a horizontal or vertical line:

The components of the directed segment PQ exists (6, 3) and we require to estimate the point, say X on the segment 1/3 of the way from P to Q. Then, the components of the segment PX exists [tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(3)\right\rangle=\langle 2,1\rangle$[/tex].

Since the initial point of the segment exists at origin, the coordinates of the point X exists given by (0+2, 0+1) = (2, 1).

where neither P nor Q exists at the origin.

Use the end points of the segment PQ to estimate the components of the directed segment.

[tex]$\left\langle\left(x_2-x_1\right),\left(y_2-y_1\right)\right\rangle=\langle(7-1),(2-6)\rangle[/tex]

= (6,-4)

The components of the segment PX where X exists a point on the segment 1 / 3 of the way from P to Q are

[tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(-4)\right\rangle=(2,-1.25)$$[/tex]

To estimate the coordinates of the point X add the components of the segment PX to the coordinates of the initial point P.

Therefore, the coordinates of the point X exists (1+2,6-1.25) = (3, 4.75).

The segments, PX and XQ, have lengths in a ratio of 1: 2.

Answer:

MP = 19

Step-by-step explanation:

MP = MN + NO + OP

we require to find OP and MN before we can evaluate MP

NO + OP = NP , that is

8 + OP = 15 ( subtract 8 from both sides )

OP = 7

and

MN + NO = M0 , that is

MN + 8 = 12 ( subtract 8 from both sides )

MN = 4

Then

MP = MN + NO + OP = 4 + 8 + 7 = 19

The rate of change of the level of the swimming pool is -0.019 inches per hour.

The rate of change will be given by the quotient between the change in the level of the water (-3/16 inches) and the time in which that change happens.

We know that the change happens between 10 pm and 7:45pm, so the number of hours is:

2 hours + 7 hours + 45 min

Where:

1 hour  = 60 min

45 min = 45/60 hours = 0.75 hour

The solution set of the given inequality is:

Or [9.52, 22.22] if we write this as an interval.

Here we have the inequality:

200 ≤ 15.75x + 50 ≤ 400

Which represents Kali's earning potential.

To solve the inequality we need to isolate the variable in the middle, if we subtract 50 in the 3 sides we get:

200 - 50 ≤ 15.75x + 50  - 50 ≤ 400 - 50

150 ≤ 15.75x ≤ 350

We are to find the number of different combinations of classes does Sylvia have to choose from.

We will be using  the following formula for number of combinations of n elements taken r (r is less than or equal to n) at a time:

Since Sylvia needs to sign up for exactly one class in each subject, so the total number of different combinations from which she has to choose will be

    ⁴C₁ * ²C₁  *  ³C₁  *  ⁵C₁

The sum of the interior angles in a triangle is supplementary. In other words, the sum of the measure of the interior angles of a triangle equals 180°. So, the formula of the triangle sum theorem can be written as, for a triangle ABC, we have ∠A + ∠B + ∠C = 180°.

In ΔOPQ,

∠O = (2x- 5)°

∠P = (3x-8)°

∠Q= (10x- 17)°

Thus by angle sum property of triangle we know:

∠O+ ∠P + ∠Q = 180

thus 2x - 5 + 3x - 8 + 10x - 17 = 180

15x - 30 = 180

= 15 x = 180 + 30

= 15 x = 210

= x= 210 / 15

= x = 14 .

Thus ∠O = (2x- 5)° = 2X 14 - 5 = 23 °

∠P = (3x-8)° = 3× 14 - 8 = 44°
