Mia walks up to a claw machine with a pocket full of quarters. She spends them at a rate of two every minute until she runs out.

Part A

If the number of quarters Mia has is graphed over time, which feature of the graph corresponds to the rate at which Mia spends the quarters?
A. the x-intercept
B. the slope
C. the y-intercept
D. the minimum value
Part B

What is the slope?
A. 2
B. 60
C. −60
D. −2

Answers

part a

The x-intercept

part b

2

The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.

And, The value of slope will be 2.

What is Equation of line?

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

She spends them at a rate of two every minute until she runs out.

Now,

Since, She spends them at a rate of two every minute until she runs out.

And, The number of quarters Mia has is graphed over time.

We know that;

Usually we represent the independent variable (time) by x and dependent variable (quarters) by y.

Hence, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.

So, The slope = 2/1

                       = 2

Thus, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters. And, The value of slope will be 2.

If P= (-3,5) and Q= (1,9), find the equation of the circle that has segment PQ as a diameter

Answers

Answer:

The equation of the circle is;

(x - [(-1))² + (y - [7])² = 8

Step-by-step explanation:

The given coordinates of the points P and Q are;

P = (-3, 5) and Q = (1, 9)

To find the equation of the circle that has segment PQ as a diameter

The equation of a circle is (x - h)² + (y - k)² = r²

Where;

(h, k) = The coordinates of the center of the circle

r = The radius of the circle

Given that segment PQ is the diameter of the circle, we have;

The center of the circle, O = The midpoint of PQ

The coordinates of the midpoint of segment PQ, O = ((-3 + 1)/2, (5 + 9)/2) = (-1, 7)

∴ The coordinates of the center of the circle, O = The coordinates of the midpoint of segment PQ = (-1, 7)

Therefore;

h = -1, k = 7

From PQ = The diameter of the required circle, we also have;

The length of PQ = 2 × (The radius of the circle) = 2 × r

The length of segment PQ = √((1 - (-3))² + (9 - 5)²) = √32 = 4·√2

Therefore;

The length of PQ = 4·√2 = 2 × r

r = (4·√2)/2 = 2·√2

r = 2·√2

r² = (2·√2)² = 8

r² = 8

The equation of the circle is therefore;

(x - h)² + (y - k)² = r²

(x - (-1))² + (y - 7)² = 8.

HEY

QUICK Question? How AM I suppose to solve using the Pythagoras's theorem

Answers

Step-by-step explanation:

heyy

so a Pythagoras theorem always works on a right angle triangle only

the longest side that is the side not involved in the right angle triangle is called the hypotenuse

the other two involved sides are called legs

so we say one leg is a

other leg is b

and hypotenuse is c

the formula is a²+b²=c²

so if a= 4cm

b=3cm

then find c

so a²+b²=c²

so 16+9=25

so square root of 25 is 5²

so c is equal to 5 cm

also if you want to check if the triangle is a right angled triangle then we should perform this theorem in which all three values will be given but you just need to solve and check if it satisfies

The area A of a triangle is given be the formula A =12bh where be is the base h is the hight of the triangle

Answer:

bh/2

Step-by-step explanation:

So first, you have to multiply the base times height and you get a value. Then, you divide the value by 2. For example, a triangle that has a base of 3 and height of 4, you would multiply 4x3 which is 12 and then divide by 2 which is 6. Hope this helps :)

For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
A. n = 65; p = 0.9
O B. n = 35; p = 0.9
C. n = 35; p = 0.8
O D. n = 65; 6 = 0.8

Answers

Answer:

n = 65; p = 0.8

Step-by-step explanation:

The sample size (n) and sample proportion () can a normal curve be

used to approximate the sampling distribution is n = 65, p = 0.8.

The correct option is D.

According to the Central Limit Theorem, the shape of sample distribution of sample proportions with a population proportion, 'p' is normal

If n·p ≥ 10 and n·(1 - p) ≥ 10.

n = 65, p = 0.8

∴ n·p = 65 x 0.8 = 52 > 10

n·(1 - p) = 65 × (1 - 0.8) = 13 > 10

For n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution.

One smartphone plan costs $52 per month for talk and messaging and $8 per gigabyte of data used each month. A second smartphone plan costs $82 per month for talk and messaging and $3 per gigabyte of data used each month. Let c represent the total cost in dollars and d represent the amount of data used in gigabytes.

The system of equations {c=52+8dc=82+3d can be used to represent this situation.
How many gigabytes would have to be used for the plans to cost the same? What would that cost be?

Both plans would cost $
if
gigabytes of data are used.

Answers

Answer:

a) 6 gigabytes

b) $100

Step-by-step explanation:

Let c represent the total cost in dollars and d represent the amount of data used in gigabytes.

For the first smartphone

One smartphone plan costs $52 per month for talk and messaging and $8 per gigabyte of data used each month.

Equation =

c = 52 + 8d

For the Second smartphone

A second smartphone plan costs $82 per month for talk and messaging and $3 per gigabyte of data used each month.

Equation =>

c = 82 + 3d

How many gigabytes would have to be used for the plans to cost the same?

We would equate both cost to each other

52 + 8d = 82 + 3d

Collect like terms

8d - 3d = 82 - 52

5d = 30

d = 30/5

d = 6

Therefore,

a) The number of gigabytes for the cost of both Smartphone data plans to be the same = 6 gigabytes.

b) The cost of both plans if 6 gigabytes is used =>

c = 52 + 8d

c = 52 + 8 × 6

c = $100
