Answer:

250 feet

Step-by-step explanation:

Vertex: (250,300)

Minimum height is 300 when the horizontal distance is 250

Step-by-step explanation:

Step 1:  Find the smallest height

If you look at the graph, you can tell that at 250 feet, the height in feet is the lowest and it is at 250.  Therefore, the vertex is also (250, 250).  But, we are just looking for the x-value which will be 250.

Answer:  Option A, 250 feet... you were correct :)  Good Job

Answer:

Step-by-step explanation:

Because of the fact that she opened a savings account and deposited $43 you are going to add that to 16x. Why? Because x represents the number of weeks she deposits $16 in her savings account. The y represents the money in her bank account, which is what we are trying to find.

I hope I've helped! Please leave a Thanks and Vote/Rate.

The correct equation representing the amount of money in Toniqua's bank account after x weeks is y = 43 + 16x. It combines the initial deposit of $43 with the $16 added each week multiplied by the number of weeks.

The question asks for an equation that represents the amount of money in Toniqua's bank account, y, after x weeks. Considering that Toniqua starts with a deposit of $43 and then adds $16 each week, the total amount of money after x weeks would be the initial deposit plus the weekly deposit amount times the number of weeks. Therefore, the correct equation would be:

y = 43 + 16x

The initial deposit is a one-time amount, so it does not multiply by the number of weeks, hence the 43 is not multiplied by x. However, the weekly deposit of $16 does multiply by the number of weeks, which gives us the 16x term in the linear equation.

The correct answer is C) 105°.

The sum of the angles in a triangle is 180 degrees. Since we know the measures of two of the angles, we can find the measure of the third angle by subtracting the sum of the first two angles from 180 degrees.

In this case, m∠X + m∠Y = 55° + 75° = 130°.

Therefore, m∠W = 180° - 130° = 50°.

However, the diagram shows angle W as an exterior angle of the triangle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles. In this case, the remote interior angles are ∠X and ∠Y.

Therefore, m∠W = m∠X + m∠Y = 55° + 75° = 130°.

Answer Choice Explanation:

A) 20° is too small.

B) 35° is too small.

C) 105° is correct.

Answer:

The average force applied to the ball is 84N

Step-by-step explanation:

This problem bothers on the impulse of a force

Given data

Mass of ball m= 0.28kg

Initial speed u= 0m/s

Final speed v= 6m/s

Time of impact t= 0.02s

We know that the impulse of a force

Ft= mv-mu

Hence the force is

F= (mv-mu)/t

F=m(v-u)/t

F= 0.28(6-0)0.02

F= 1.68/0.02

F= 84N

The required probability that the marble is not yellow and not blue is 7/12. Option C is correct.

Given that,
A marble is drawn at random from a bag containing 2 blue marbles, 3 yellow marbles, and 7 orange marbles.

Probability can be defined as the ratio of favorable events to the total number of outcomes.

Here,

blue = 2
yellow = 3
orange = 7
The probability that the marble is not yellow and not blue,
= 1 - 2/12 - 3/12
= [12 - 2 - 3] / 12
= 7/12

Thus, the required probability that the marble is not yellow and not blue is 7/12. Option C is correct.

To solve the equation 3tan^2 = sqrt3 tanx for all real values of x, divide both sides of the equation by tan(x) and then take the inverse tangent of both sides. The solutions for x are 30°, 210°, 390°, ...

To solve the equation 3tan^2 = sqrt3 tanx for all real values of x, we can start by rearranging the equation. Divide both sides of the equation by tan(x) to get:

3tan(x) = sqrt3

Next, divide both sides of the equation by 3 to get:

tan(x) = sqrt3/3

Now, we need to find the values of x where the tangent function equals sqrt3/3. We can use the inverse tangent function to find the angles. Taking the inverse tangent of both sides gives:

x = arctan(sqrt3/3)

Final answer:

To calculate how much lower Ashlee's monthly payment will be if she purchases the points, we first need to calculate her monthly payment with and without the points. Ashlee will make a 20% down payment on the $125,000 home. By purchasing the points, Ashlee will lower her interest rate by 2%. The difference in monthly payments is approximately $115.44.

Explanation:

To calculate how much lower Ashlee's monthly payment will be if she purchases the points, we first need to calculate her monthly payment with and without the points.

1. Calculate the loan amount: Ashlee will make a 20% down payment on the $125,000 home, which is $25,000. So, the loan amount will be $125,000 - $25,000 = $100,000.

2. Calculate the monthly payment without the points: Using the loan amount of $100,000, the interest rate of 4.75%, and the loan term of 30 years, we can use a mortgage calculator to find the monthly payment. The monthly payment without the points is approximately $522.62.

3. Calculate the monthly payment with the points: Ashlee is considering purchasing 2 points. Each point is equal to 1% of the loan amount, so 2 points would be 2% of $100,000, which is $2,000. By purchasing the points, Ashlee will lower her interest rate by 2% to 4.75% - 2% = 2.75%. Using the loan amount of $100,000, the new interest rate of 2.75%, and the loan term of 30 years, we can again use a mortgage calculator to find the monthly payment. The monthly payment with the points is approximately $407.18.

4. Calculate the difference in monthly payments: The difference in monthly payments is $522.62 - $407.18 = $115.44. Therefore, Ashlee's monthly payment will be approximately $115.44 lower if she purchases the points.

Ashlee's monthly payment would be approximately $50.44 lower if she purchases 2 points.

1. Calculate the loan amount after the down payment:

Down payment amount = 20% * $125,000 = $25,000

Loan amount = $125,000 - $25,000 = $100,000

2. Calculate the monthly payment without buying points:

Convert the interest rate to a decimal: 4.75% = 0.0475

Number of months in the loan term: 30 years * 12 months/year = 360 months

Use a mortgage calculator or the following formula to calculate the monthly payment:

Monthly payment = (Loan amount * Interest rate * (1 + Interest rate)^Number of months) / ((1 + Interest rate)^Number of months - 1)

3. Calculate the cost of buying 2 points:

Each point typically costs 1% of the loan amount.

Cost of 2 points = 2 points * 1% * $100,000 = $2,000

4. Calculate the reduced interest rate with points:

Each point usually reduces the interest rate by 0.25%.

Reduced interest rate = Original interest rate - Points reduction * Number of points

Reduced interest rate = 0.0475 - 0.0025 * 2 = 0.0425

5. Calculate the monthly payment with points:

Use the same formula as in step 2 but with the reduced interest rate.

6. Calculate the difference in monthly payments:

Difference = Monthly payment without points - Monthly payment with points

Example calculation:

Let's assume the monthly payment without points is $522.62 (calculated using a mortgage calculator) and the monthly payment with points is $472.18.

Difference in monthly payment = $522.62 - $472.18 = $50.44

Therefore, Ashlee's monthly payment would be approximately $50.44 lower if she purchases 2 points.

C features a slope of +4 and a y-intercept of +2

Step-by-step explanation:

Only the middle two answers feature a slope of +4, so eliminate answers A and D.  Answer C features a slope of +4 and a y-intercept of +2

The equation of a line in slope-intercept form for a line with slope 4 and y-intercept at (0, 2) is C. y = 4x + 2.

In the slope-intercept form of a linear equation, y = mx + b, 'm' represents the slope and 'b' represents the y-intercept. If we substitute the given values into this equation, with m = 4 (the slope) and b = 2 (the y-coordinate of the y-intercept), we get y = 4x + 2. So, the correct answer is C. y = 4x + 2.
