Answer 1

Answer:

5/4

Step-by-step explanation:

First plot any2 points. Next count how many units it is High and Left/Right to get to the second point!

(Added your graph for further explaination :)

Answer 2

First, determine 2 points on the graph. I'd recommend to choose 2 points that are next to each other to make it easier.

Second, see how many units higher the first point you chose (on the left) is than the second point you chose (on the right). Say it is 3 units, then you mark a points 3 units above the first point.

Third, see how many units to the right the second point is to the first. If it is 5 units, you would go to the point you marked on the previous step, and move 5 units to the right. If you did it correctly, it should end up on the second point you chose. The segment you drew should kind of look like a box.

Now, make a proportion. Put how many units you rose in the second step at the top, and how many you ran at the bottom. Treat this like a fraction and simplify. You have your slope!

Going higher and to the right is the formula rise/run. How many units do you rise, how many do you go right? I recommend doing this when finding slope on a graph

Hope I helped!!!!!!!!!!!!! :)

The temperature in Vancouver was recorded over a period of four hours. The equation y = -2x + 43 describes the temperature over this time, where y is the temperature in degrees Fahrenheit (°F) and x is the number of hours since measurements started. Which of the following statements correctly describes the temperature? A. It was -2°F when the temperature was first measured, and it is rising by 43 degrees per hour. B. It was 43°F after four hours, and it is dropping by 2 degrees per hour C. It was -2°F after four hours, and it is rising by 43 degrees per hour D. It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour

Step-by-step explanation:

I had the same quiz

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.

Option D is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 8 is an equation.

We have,

y = -2x + 43

Where y is the temperature after x hours.

Now,

At x = 0,

y = 43

This means the temperature is 43 when it first started to measure.

At x = 1,

y = 41

This means,

The temperature decreases by 2 degrees per hour

Thus,

It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.

Option D is the correct answer.

Sam has some pennies, dimes and nickels in his pocket which total 52 cents. He has two more nickels than dimes and three times as many pennies as nickels. How many of each coin does he have?

Answers

Answer:

Step-by-step explanation:

Let the amount of pennies be x

amount of dimes be y

amount of nickels be z

If it all totaled 52, then x+y+z = 52

If he has two more nickels than dime, then;

z = y + 2

y = z-2

If he has three times as many pennies as nickels;

3x = z

x = z/3

Subtitute the funcion in original function;

z/3 + (z-2) + z = 52

z + 3z - 6 + 3z = 156

7z - 6 = 156

Step-by-step explanation: In mathematics, a product is the result of multiplication, or an expression that identifies factors to be multiplied. The two numbers that are being multiplied are called factors. For example, 30 is the product of 6 and 5, and is the product of and.

△ABC is reflected over the x−axis and then reflected over the y−axis to form ΔA''B''C'' as shown below.

Answers

Answer:

Step-by-step explanation:

Because it is.

The general rule maps △ABC onto ΔA''B''C'' is (x,y) turns to (x, -y). so option C is correct.

How does reflection across axis work?

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

Thus, if we are reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if we are reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)

△ABC is reflected over the x−axis and then reflected over the y−axis to form ΔA''B''C'' is shown.

The general rule maps △ABC onto ΔA''B''C'' is (x,y) turns to (x, -y). so option C is correct.

Statistics and probability: If the glucose level is above 160mg per dl one hour after a sugary drink, Sheila's measured glucose level one hour after the sugary drink varies according to the normal distribution with the mean being 145mg/dl and a standard deviation of 11mg/dl. If a single glucose measurement is made, what is the probability that Sheila is diagnosed with gestational diabetes?

Answers

Answer:

0.0863

Step-by-step explanation:

Given that:

The mean =145

The standard deviation = 11

To find P(X ≥ 160) :

Z = (x - μ)/σ

Z = 160 - 145/ 11

Z = 1.364

From the standard normal z table

Thus;

P(X ≥ 160) = 1- P(Z < 1.364)

P(X ≥ 160) = 1 - 0.9137

P(X ≥ 160) = 0.0863

(PLEASE SOLVE ASAP!!) Suppose the entry fee to Arches national park is $25 per vehicle. Suppose the entrance fee to Bryce national park can be represented by the equation y=30x, where y represents the total cost in dollars, and x represents the number of vehicles. Which park has the greatest cost per vehicle?

Answers

Answer:

Bryce national park has the greatest cost per vehicle.

Step-by-step explanation:

From the question, we are given the following:

For Arches national park

Cost per vehicle or entry fee per vehicle at Arches national park = $25

For Bryce national park

We have:

y = 30x ........................... (1)

y = the total cost in dollars

x = the number of vehicles

To obtain the cost per vehicle at Bryce national park, we have to assume that the number of vehicles is one by setting x equal to one, that is, x = 1.

Substituting x = 1 into equation (1), we have:

y = 30 * 1 = 30

This implies that cost per vehicle at Bryce national park is $30.

Conclusion

Since the $30 cost per vehicle at Bryce national park is greater than the $25 cost per vehicle at Arches national park, it therefore implies that Bryce national park has the greatest cost per vehicle.

A tree casts a shadow that is 125 feet in length. The angle of elevation with the sun is 32°. What is the height of the tree?

Answers

Answer:

Height of the tree is 78.11 feet.

Step-by-step explanation:

By applying the tangent rule in the right triangle formed,

Since, tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(32)° = [tex]\frac{h}{125}[/tex]

h = 125(tan32°)

h = 125(0.62487)

h = 78.109

≈ 78.11 ft

Height of the tree will be 78.11 feet.
