Sophia is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The one-time fee to join the gym is $100 and the total cost of membership, including the joining fee, would be $300 for 5 months. Write an equation for C,C, in terms of t,t, representing the total cost of the gym membership over tt months.

Answers

Answer:

40t+100

Step-by-step explanation:

The equation that represents the total cost of the gym membership over t months is C = 40t + 100.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The one-time fee to join the gym is $100 and the total cost of membership, including the joining fee, would be $300 for 5 months

Based on the data given in the question:

The linear equation can be framed as follows:

C = 40t + 100

Here C represents the total cost of the gym membership over t months.

Thus, the equation that represents the total cost of the gym membership over t months is C = 40t + 100.

Suppose the radius of the cylinder is decreasing at a rate of 2 cm/sec, but the volume is constant. How fast is the height changing when the radius is 10 cm and the height is 35 cm? Include units with your answer. Hint: If the volume is constant, what do you know about the rate of change of the volume?

Answers

The height changing at "14 cm/s".

According to the question,

r = 10 cmh = 35 cm[tex]\frac{dr}{dt} = -2 \ cm/s[/tex]

As we know the formula,

[tex]V = \pi r^2 h[/tex]

then,

→ [tex]\frac{dv}{dt} = \pi [2r\frac{dr}{dt} h+ r^2 \frac{dh}{dt} ][/tex]

→ [tex]0 = \pi [2 \pi h\frac{dr}{dt} + r^2 \frac{dh}{dt} ][/tex]

By substituting the given values,

→ [tex]0 = 2\times 10\times 35\times (-2)+(10)^2\times \frac{dh}{dt}[/tex]

[tex]\frac{dh}{dt} = \frac{2\times 10\times 35\times 2}{10\times 10}[/tex]

[tex]\frac{dh}{dt} = \frac{140}{10}[/tex]

[tex]\frac{dh}{dt} = 4 \ cm/s[/tex]

Thus the answer above is right.

You are to take a multiple-choice exam consisting of 100 questions with 2 possible responses to each question. Let x represent the number of correct responses on the test. A) What is your expected score on the exam?B) Compute the variance and standard deviation of x.

Answers

Answer:

50 ;

25 ;

Step-by-step explanation:

Given that:

Number of multiple choice questions = 100

Number of possible responses = 2

Hence, probability of success, p = 1/2 = 0.5

Using normal approximation :

The expected score = mean = n*p

Expected score (X) = 100 * 0.5 = 50

standard deviation = std(X) = √

Var(X) = n*p*q

q = 1 - p = 1 - 0.5 = 0.5

Variance = Var(X) = (100 * 0.5 * 0.5)

Var(X) = 25

The Standard deviation (Std) = √Var(X)

Std(X) = √25

Std(X) = 5

A map has a scale of 2 inches = 50 miles. If the
distance between two cities on the map is 7 inches,
what is the actual distance between the cities?

Answers

Answer:

175 miles apart.

Step-by-step explanation:

This is because 2 goes into seven 3 times and half of 50 is 25 so for 1 inch it would be 25 miles. 50+50+50+25=175 miles.

You have discovered another alien. Find the correct rescue path before answering this question. Which statements are true about the equation of the line used to save this alien? The y-intercept is not visible on the graph. The slope does not exist for this line. The y-intercept is positive. The line crosses the x-axis at –3.

Answers

The correct answers are option A and option D.

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

From the given graph it is clear that the spaceship is located at (-4,3). The alien is at (-2, -3).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

y - 3 = (-3 -3 ) / (-2 + 4) x (x + 4)

y - 3 = -3x -12

y = -3x -9

The equation of the line is;

y = -3x -9 {equation 1}

Slope intercept form of a line is

y = mx + b {equation 2} ,

where m is the slope and b is the y-intercept.

On comparing the equation (1) and (2) we get

It means,

Slope = -3

y-intercept = -9

Points from -6 to 6 are labeled on y-axis. The y-intercept is -9, so it is not visible on the graph.

Option A is correct.

Substitute y=0 in equation (1) to find the x-intercept.

Divide both sides by 3.

x-intercept is -3. It means the line crosses the x-axis at -3.

Option D is correct

Therefore, the correct options are A and D.

One number is 4 more than the other. The difference between their squares is 72. What are the numbers

Answers

We have to set up 2 different equations if we are to solve for 2 unknowns. The first equation is x = y + 4. One number (x) is (=) 4 more than another (y + 4). Since we have determined that x is larger (cuz it's 4 more than y), when we set up their difference, we are going to subtract y from x cuz x is bigger. The second equation then is . In our first equation we said that x = y + 4, so let's sub that value in for x in the second equation: . Expand that binomial to get . Of course the y squared terms cancel each other out leaving us with 8y + 16 = 64. Solving for y we get that y = 6. Subbing 6 in for y in our first equation, x = 6 + 4 tells us that x = 10. Yay!
