Which graph represents a proportional relationship?

Answers

Answer:

The one shown in the photo

Step-by-step explanation:

A proportional relationship is one in which the relationship increases steadily, which looks like a straight line when graphed. Also, the line should pass through the origin, which is the point (0, 0) on a graph.

The graph shown increases steadily (it's a straight line), and passes through the origin (point 0,0) as well. So, it's proportional. Hopefully that's helpful! :)

Show all necessary math work. (3 points) Part B: If (r, s) = (7, –4) and t = 10, determine the domain and range of the circle. (4 points) Part C: Is the point (9, 1) inside the border of the circle if (r, s) = (7, –4) and t = 10? Explain using mathematical evidence. (3 points)

Answers

Answer:

Part A, write out the equation by subtracting the vertex from x and y, then set it equal to the radius square. All of this information is given in the picture. Then the domain is all the x's and the range is all the y's starting at the center and going out 10 in each direction since 10 is the radius.

Step-by-step explanation:

Use the circle formula that you learned in lesson 3.02 using the given points. Remember this quiz was open note and your formula should be in your notes. Also, it should be familiar to you from Geometry and middle school math where you first learned about circles:)

answer this asap please its emergency

Answers

Step-by-step explanation:

emergency ? why ? you are in the middle of a game with such an unfair die ?

the probabilty for a number of a regular die is 1/6 (desired cases divided by total possible cases).

the probability to role an even number is therefore 3/6 = 1/2.

that means, even and odd are the 2 possible outcomes.

now, for the unfair die we can see it as if we have now 4 possible outcomes : 3 times an even number, and 1 time an odd number.

so, the probability to roll an even number is 3/4 (and for an odd number 1/4).

now, we roll it twice.

for the sum to be even, we either have to roll 2 even numbers or 2 uneven numbers.

the probabilty is the sum of the both probabilities (it is an exclusive "or" relationship).

the probability to roll 2 even numbers is

3/4 × 3/4 = 9/16

the probability to roll 2 uneven numbers is

1/4 × 1/4 = 1/16

the sum is

9/16 + 1/16 = 10/16 = 5/8

so, E is the right answer.

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend.

"Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the fuel gauge. The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the vehicle Renter. One copy of the Check-Out sheet will be given to the customer. Another copy will be kept with the on-site records of the vehicle.

"The rented vehicle must be returned with a minimum fuel level the same as that indicated on the Check-Out sheet. A vehicle returned with a fuel level less than the approximate level indicated on the Check-Out sheet will be completely refueled with on-site pumps. The price of the fuel used to refuel the vehicle will be added to the Renter's total charge at a cost of $4.50 per gallon plus a $5.00 refueling charge."

Tim forgot to refuel the vehicle when he returned it. His Check-Out sheet indicates that the vehicle had about 1/2 of a tank left. The tanks is now nearly empty.

If it takes 11.75 gallons of gas to refuel the car Tim rented, how much extra should he expect to pay because he forgot to get gas?
a.
$26.44
b.
$31.44
c.
$52.88
d.
$57.88

Answers

Answer: D

Step-by-step explanation:

Tim should expect to pay an extra $52.88 because he forgot to refuel the car. option D is correct.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The car that Tim rented needed 11.75 gallons of gas to refill to the same fuel level as indicated on the Check-Out sheet.

Since the rental agency charges $4.50 per gallon of gas plus a $5.00 refueling charge, the cost of refueling the car will be:

11.75 gallons x $4.50/gallon + $5.00

= $57.88

Therefore, Tim should expect to pay an extra $57.88 because he forgot to refuel the car. The correct answer is (d).

The ratio of trees to shrubs is 5:2. How many shrubs are there for 30 trees?

Answers

Answer:

30:12

Step-by-step explanation:

The beginning ratio is 5:2, trees to shrubs.

For every five trees, there are two shrubs.

So here is how we are going to solve the problem, since we are trying to figure out the amount of shrubs for 30 trees, we are going to divide 30 by 5 then once we've found out the quotient, we are going to multiply the quotient by two to get our amount of shrubs.

30 ÷ 5 = 6

6(2)=12

To conclude, for 30 trees there are 12 shrubs.

This assumes you were given the mass of mars to be [tex]6.39*10^2^3kg[/tex] the mass of the sun to be [tex]1.99*10^3^0kg[/tex] and the gravitational force between the two to be [tex]3.72*10^3^5N[/tex].

Find the lcm of 4 and 4?

Answers

Answer:

lowest common multiple of 4 and 4 is 4

To verify those for alpha and beta, simply substitute the known values:

sin 30° = cos 60° = 1/2

sin 60° = cos 30° = √3/2

cos 90° = sin 0° = 0

sin -30° = -1/2

sin 120° = √3/2

a.

cos 90° = cos 30° cos 60° - sin 30° sin 60°

0 = √3/2 * 1/2 - 1/2 * √3 / 2 = √3/4 - √3/4 = 0

verified

b.

sin -30° = sin 30° cos 60° - cos 30° sin 60°

-1/2 = 1/2 * 1/2 - √3/2 * √3/2 = 1/4 - 3/4 = -2/4 = -1/2

verified

c.

sin 120° = 2 sin 60° cos 60°

√3/2 = 2 * √3/2 * 1/2 = √3/2

C. deposition
D. erosion

Answers

Answer:

D. erosion

Step-by-step explanation:

The wind is a stronger erosional force in arid regions than it is in humid regions because winds are stronger. In humid areas, water and vegetation bind the soil so it is harder to pick up. In arid regions, small particles are selectively picked up and transported. As they are removed, the ground surface gets lower and rockier, causing deflation. What is left is desert pavement, a surface covered by gravel-sized particles that are not easily moved by wind.
