Slope: 50x

One point will be: (1,50)

Equation: y = 50x

Step-by-step explanation:

Answer 2

Answer:

The slope of the linear equation is *50

One point on the graph of the linear equation will be *(3, 150)

Select the correct answer

which situation is best modeled by a nonlinear function with time as the independent variable?

A. The value of a gift card that decreases by three dollars each month

B. The value of a $20 bill

C. The value of a collectible baseball card that increases by constant factor of 1.1, or by 10%, each year

D. The value of an investment that increases by two dollars each week

Answers

Answer: Most likely it is A

Step-by-step explanation:

Although it should be B, because a non linear function doesn't have a rate of change. I already looked up this question many times so we know It's NOT C.

The best modeled by a nonlinear function with time as the independent variable is:

The value of a collectible baseball card that increases by a constant factor of 1.1, or by 10%, each year.

A nonlinear function is one that does not follow a straight line.

In this case, t

A) describes a linear function since the value of the gift card decreases by a fixed amount each month, resulting in a straight-line relationship.

B) describes a constant value, which is a special case of a linear function where there is no change over time.

C) The value of the collectible baseball card increases by a constant factor of 1.1 each year, which results in exponential growth. This behavior is best modeled by a nonlinear function.

D) describes a linear function since the value of the investment increases by a fixed amount each week, resulting in a straight-line relationship.

Sassan finds that 2 pints 1 cup of water has evaporated from the class aquarium. How many pints of water are left in the aquarium

Answers

The pints of water left in the aquarium is 2.5 pints

Converting cups to pint

Using the conversion rule sho below:

1 cup = 0.5 pint

If Sassan finds that 2 pints 1 cup of water have evaporated from the class aquarium, the total pint that evaporated is expressed as:

Total pint = 2 pints + 0.5 pint

Total pint = 2.5 pints

If LOVE is a square with LO = 2x + 3 and OV = 9, what is the value of x?

Answers

Answer:

Step-by-step explanation:

2x+3=9

You have to get rid of the 3 and the operation that is happening between the 2x and 3 is addition so you must do the opposite which is subtract .

2x+3-3=9-3

Cross out the 3's . What you do to one side do it to the other side .So subtract 3 from both sides .

2x÷2=6÷2

Now to get rid of the 2 you divide because the operation that is happening between the 2 and x is multiplication.And what u do to one side do it to the other . So

x= 3

Of 600 people surveyed, 220 were male and 350 had cell phones. Of those with cell phones, 230 were female. What is the probability that a person surveyed was either male or had a cell phone?
A)100/600 ≈ 0.167
B)480/600 = 0.8
C)340/600 ≈ 0.567
D)450/600 = 0.75

Answers

By definition of probability, the probability that a person surveyed was either male or had a cell phone is [tex]\frac{450}{600}[/tex]= 0.75

Definition of Probabitity

Probability is the greater or lesser possibility that a certain event will occur.

In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.

Union of events

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.

Probability that a person surveyed was either male or had a cell phone

In first place, let's define the following events:

M: the person surveyed was male.C: the person surveyed had a cell phone.

The probability that a person surveyed was either male or had a cell phone is calculated as:

P(M∪C)= P(M) + P(C) -P(M∩C)

In this case, you know:

P(M)= [tex]\frac{220}{600}[/tex]P(C)= [tex]\frac{350}{600}[/tex]P(M∩C)= [tex]\frac{120}{600}[/tex] (Of the 350 people who have cell phones, 230 are female. This means the remaining 120 people with cell phones are male.)

Replacing in the definition of probability:

P(M∪C)= [tex]\frac{220}{600}[/tex] + [tex]\frac{350}{600}[/tex] - [tex]\frac{120}{600}[/tex]

Solving:

P(M∪C)= [tex]\frac{220+350 -120}{600}[/tex]

P(M∪C)= [tex]\frac{450}{600}[/tex]= 0.75

Finally, the probability that a person surveyed was either male or had a cell phone is [tex]\frac{450}{600}[/tex]= 0.75

The nth term of a different arithmetic sequence is 3n + 5
(b) Is 108 a term of this sequence? Show how you get your answer.

Answers

Answer:

No 108 is not a term of this sequence.

Step-by-step explanation:

3n+5 = 108

3n = 108 - 5

3n = 103

Divide both side with 3.

n = 103/3

n = 34.33

since n is not equal to 108 there it is not

Answer:

see below

Step-by-step explanation:

We can determine if 108 is a solution by setting 3n+5 =108

3n+5= 108

Subtract 5 from each side

3n+5-5=108-5

3n = 103

Divide by 3

3n/3 = 103/3

n = 103/3

This is not an integer so 108 is not a solutions

The measures of the angles of triangle PQR can be represented in terms of x
The measure of angle P is (2x)
The measure of angle Q is
(x+17)
The measure of angle R is (x-21)
Create an equation that can be used to find the measure of each angle.

Answers

Answer:2x+(x+17)+(x-21)=180

Step-by-step explanation:

Angles in a triangle add to 180 degrees.

The equation that can be used to find the measure of each angle is 2x + x + 17 + x - 21 = 180

How to create an equation to determine the angles?

The given parameters are:

P = 2x

Q = x + 17

R = x - 21

The sum of angles in a triangle is 180.

So, we have:

P + Q + R = 180

Substitute known values

2x + x + 17 + x - 21 = 180

Hence, the equation that can be used to find the measure of each angle is 2x + x + 17 + x - 21 = 180

The information on the graph shows a positive nonlinear correlation and the weight of the dinosaur tends to increase according to its length.

What is a discrete graph?

A discrete graph is also known as a scatter plot that shows the discontinuous and the nonlinear data point on the graph.

From the graph, we can see the increasing weight of the Dinosaur size vertical y-axis and the increasing length of the feet on the horizontal x-axis.

Therefore, we can conclude that the data points show an increasing nonlinear weight on the graph as the length increases.

Perimeter of base: 40 :)

Slant height: 13

Area of base: 100

10^2 = 100

Surface area: 65000

(1/2)(100 x 13)

1/2(1300)

650

Have an amazing day!!

Please rate and mark brainliest!!!

Answer and Explanation:

1) The perimeter is the sum of the base's side lengths, so it is:

P = 10 ft * 4 = 40 ft

2) The height can be calculated using the Pythagorean Theorem. Take half of the base's side length for the short leg (5 ft) and the slant height (13 ft) for the hyptenuse:

5^2 + h^2 = 13^2

25 + h^2 = 169

h^2 = 144

h = 12 ft

3) To find the lateral area, take the area of one of the triangular faces of the pyramid and multiply it by 4, since there are 4 triangular faces:

LA = 4 * (1/2)(10 * 13)

= 4 * 65

= 260 ft

4) The area of the base is the product of its dimensions:

A(base) = 10 * 10

= 100 ft^2

5) Surface area is the sum of the lateral area and the base's area, so just plug in the values from problems 3 and 4:

SA = LA + A(base)

= 260 + 100

= 360 ft^2

A random number, x, is generated, where x is any real number.

(a) Manuel adds 2 to x. He subtracts x from 10. Manuel then multiplies these two results to give his number, y.

Show that y = 20 + 8x - x?.

Answers

Step-by-step explanation:

Say that x = 1, since x can be any real number.

From part a -> x +2 = 3

and -> 10-x =9

then multiply the two results to get y -> 3x9 = 27

Now look at y=20+8x-x and plug in the same value for x where x = 1

you get -> y = 20 + 8(1) -(1) which simplifies out to 27. Therefore the equation is proven since they equal the same value.
