Answer:

C. $1246.82

Step-by-step explanation:

Using the factor shown in the table for a 25-year loan at 5.25%, the calculated payment is ...

5.992·(244.8·0.85) = 1246.82

The factor of 0.85 on the home price represents the effect of subtracting 15% from the price to get the loan value. Of course, the home price is the number of thousands, so is 244.8 thousand.

_____

If you do the calculation, rather than use a factor from a table, you get a mortgage payment value of $1246.91. This suggests that the numbers in the table need more significant digits for loan values this high.

Answer:

So, marta will sprint 225 yards.

Step-by-step explanation:

Area of parallelogram= b*h

Given: Area = 776.5 square yards

Base = 34.5 yards

Area = b* h

776.5 = 34.5 * h

776.5/34.5 =h

=> h = 22.5

Since sprint is the same distance as of height of park so,

Distance of  1 sprint = 22.5 yards

Distance of  10 sprints = 10 * 22.5 = 225 yards

Step-by-step explanation:

The truck cannot drive under the archway since it is taller than the highest point of the archway.

To determine if a truck can drive under the semielliptic archway without going into the other lane, we need to compare the height and width of the truck to the height and width of the archway. The truck has a height of 12 feet and a width of 14 feet. The highest point of the archway is at its center, which is 15 feet high. So, the truck will not fit under the archway since it is taller than the highest point of the archway.

Add the square of half the x coefficient: (-2/2)^2 = 1.

Answer:

Step-by-step explanation:

There are a few ways you can write the equivalent of this.

1) Distribute the minus sign. The starting numerator is -(u-6). After you distribute the minus sign, you get -u+6. You can leave it like that, so that your equivalent form is ...

  (-u+6)/(u+2)

Or, you can rearrange the terms so the leading coefficient is positive:

  (6 -u)/(u +2)

__

2) You can perform the division and express the result as a quotient and a remainder. Once again, you can choose to make the leading coefficient positive or not.

  -(u -6)/(u +2) = (-(u +2)-8)/(u +2) = -(u+2)/(u+2) +8/(u+2) = -1 + 8/(u+2)

or

  8/(u+2) -1

Of course, anywhere along the chain of equal signs the expressions are equivalent.

__

3) You can separate the numerator terms, expressing each over the denominator:

(-u +6)/(u+2) = -u/(u+2) +6/(u+2)

__

4) You can also multiply numerator and denominator by some constant, say 3:

  -(3u -18)/(3u +6)

You could do the same thing with a variable, as long as you restrict the variable to be non-zero. Or, you could use a non-zero expression, such as 1+x^2:

  (1+x^2)(6 -u)/((1+x^2)(u+2))

The value of 'b' in the quadratic equation [tex]4x^2+bx+9=0[/tex] must result in a negative discriminant, which means [tex]b^2[/tex] must be less than 144 for the equation to have no real number solutions.

For a quadratic equation [tex]ax^2+bx+c=0[/tex] to have no real number solutions, its discriminant must be negative. The discriminant is given by the formula [tex]b^2-4ac[/tex]. In the case of the equation [tex]4x^2+bx+9=0[/tex], a is 4 and c is 9. For this equation to have no real solutions, the value of b must be such that [tex]b^2-4(4)(9)[/tex] is less than 0. This simplifies to [tex]b^2-144 < 0[/tex]. Therefore, for the student's equation to have no real number solutions, the value of b must satisfy [tex]b^2 < 144.[/tex]

For the quadratic equation 4x² + bx + 9 = 0 to have no real roots, the discriminant must be negative, which leads to the requirement that b² < 144.

To determine what must be true about b in the quadratic equation 4x² + bx + 9 = 0 with no real number solutions, we consider the discriminant of a quadratic equation, which is given by the formula Discriminant = b² - 4ac. For the given equation, a equals 4 and c equals 9. In order for a quadratic equation to have no real roots, the discriminant must be negative. Therefore, our inequality becomes b² - 4(4)(9) < 0, which simplifies to b² < 144. Therefore, the requirement for the quadratic equation to have no real solutions is that the square of b must be less than 144, elucidating the crucial role of discriminants in determining the nature of solutions in quadratic equations.

The surface area of a cylinder is given by

[tex]A_A = 2\pi rh[/tex]

which is the surface area of cylinder A.

To compute the surface area of cylinder B, we have to map [tex](r,h)\mapsto (2r, 2h)[/tex] and we have the following formula

[tex]A_B = 2\pi(2r)(2h)[/tex]

If we manipulate the second expression, we have

[tex] A_B = 8\pi rh[/tex]

Which implies

[tex]\dfrac{A_B}{A_A} = \dfrac{8\pi rh}{2\pi rh} = 4 [/tex]

First find the gradient of the perpendicular line. You do this by taking the negative reciprocal of the gradient of the first line (y= 1/4x +3):

Perpendicular gradient = negative reciprocal of [tex]\frac{1}{4}[/tex] = -4

Next, you substitute the x and y values into the following equation and solve:

y = -4x +c

-2 = -4(-4) +c

-2 = 16 + c

-18 = c

Substitute c back into the equation above to get the final answer:

y = -4x -18

The solution in the attached figure

Step-by-step explanation:

Let

x------> the numbers of boxes of popcorn sold

y-----> the number of boxes of pretzels sold

we know that

[tex]2x+5y\geq 500[/tex] ----> inequality that represent the situation

using a graphing tool

The solution is the shaded area above the solid line [tex]2x+5y=500[/tex] between the positive values of x and the positive values of y

see the attached figure

We aim to earn $500+, selling popcorn at $2/box and pretzels at $5/box. Equation: [tex]\( y \geq \frac{500 - 2x}{5} \)[/tex], where ( x ) is the number of popcorn boxes.

let's break down the problem step by step:

1. Let's define our variables:

  - ( x ): Number of boxes of popcorn sold

  - ( y ): Number of boxes of pretzels sold

2. We are given the following information:

  - The team earns $2 for every box of popcorn sold.

  - The team earns $5 for every box of pretzels sold.

  - The team wants to earn at least $500 from all sales.

3. We can express the total earnings from selling popcorn and pretzels using the given information:

  - Total earnings from popcorn sales: ( 2x )

  - Total earnings from pretzel sales: ( 5y )

4. Since the team wants to earn at least $500, we can write this as an inequality:

[tex]\[ 2x + 5y \geq 500 \][/tex]

Now, let's solve this inequality for \( y \):

[tex]\[ 2x + 5y \geq 500 \][/tex]

[tex]\[ 5y \geq 500 - 2x \][/tex]

[tex]\[ y \geq \frac{500 - 2x}{5} \][/tex]

So, the number of boxes of pretzels sold, ( y ), should be greater than or equal to[tex]\( \frac{500 - 2x}{5} \).[/tex]

Now, let's plot this inequality on a graph.

- Choose a few values of ( x ) and find the corresponding values of ( y ) using the inequality.

- Plot these points on the graph.

- Draw a line that passes through these points, and it should be a solid line because of the "greater than or equal to" sign.

- Shade the area above the line because ( y ) should be greater than or equal to[tex]\( \frac{500 - 2x}{5} \).[/tex]

Let's choose a few values of ( x ) to plot:

1. When ( x = 0):

[tex]\( y = \frac{500 - 2(0)}{5} = \frac{500}{5} = 100 \)[/tex]

2. When ( x = 100 ):

 [tex]\( y = \frac{500 - 2(100)}{5} = \frac{500 - 200}{5} = \frac{300}{5} = 60 \)[/tex]

3. When ( x = 200 ):

[tex]\( y = \frac{500 - 2(200)}{5} = \frac{500 - 400}{5} = \frac{100}{5} = 20 \)[/tex]

Answer:

Step-by-step explanation:

1. Any linear equation that describes a line with non-zero slope through the vertex of the parabola will intersect the parabola at two points (the vertex being one of them). A simple equation for such a line is y=x.

__

2. Differentiating the equation, you find that the slope of the curve y = x^2 is 2x, so if we choose a line with a slope of 1, it will go through the point on the curve with x-value equal to 1/2. The y-value at that point is y = (1/2)^2 = 1/4, so the y-intercept of the line must be -1/4.

The line that intersects the curve at one point (1/2, 1/4) is tangent at that point. It has equation y = x -1/4.

__

3. Any line with the same slope as the tangent line, but a more negative y-intercept, will not intersect the parabola at all. Such a line is y = x -1/2.

_____

Truth be told, I found the line y = x -1/2 did not intersect the parabola at all when I thought I was writing the equation for the tangent line. It was an answer to part of your question, just not the part I originally intended.

Answer:

A linear equation that intersects at two points would be y = 1x. A linear equation that only has one intersect point would be y=0. finally, a linear equation that has no intersect point would be y = x - 4. I could these by plotting them on a graph and finding out that these will work.

The initial yield of potatoes per acre was 14 tons and after the introduction of the new technology, the yield increased to 18 tons. Therefore, 5600 tons were collected before the technological advances and 7200 tons were collected after.

This problem involves understanding linear equations. Let's denote the initial yield of potatoes per acre as 'x' tons and the yield after the introduction of the new technology as 'y' tons.

It's given that technological advances increase the yield by 4 tons, so we have the equation: y = x + 4. The problem also states that from a 320 acre field 640 more tons were collected than before from a 400-acre field. So, we can write it as: 320y = 400x + 640.

Solve these two equations to find the values of x and y. The initial yield of potatoes per acre (x) was 14 tons while the yield after the introduction of the new technology (y) was 18 tons. Therefore, 5600 tons of potatoes were collected before the technological advances and 7200 tons were collected after.

https://brainly.com/question/4177820

#SPJ12

Before the new methods were introduced, 640 tons of potatoes were collected. After the introduction of the new technology, 0 tons were collected.

To solve this problem, let's assume x is the number of tons of potatoes collected before the new methods were introduced, and y is the number of tons collected after the introduction of the new technology.

According to the given information, the new technology increased the crop of potatoes from 1 acre by 4 tons, so the increase in yield per acre is 4 tons.

From a field of 320 acres, 640 tons more were collected than before from a field of 400 acres. This means that the increase in yield from the reduced field of 320 acres is twice the increase in yield from the initial field of 400 acres.

Setting up the equation, we have:

(y - x) = 2(4)(320 - 400)

(y - x) = 2(4)(-80)

(y - x) = -640

We also know that the total increase in yield is 640 tons, so we have:

x + y = 640

To solve these equations, we can use substitution or elimination method. Solving for x in the second equation, we get:

x = 640 - y

Substituting x in the first equation, we have:

(y - (640 - y)) = -640

2y - 640 = -640

2y = 0

y = 0

Substituting y in the equation x + y = 640, we get:

x + 0 = 640

x = 640

Therefore, before the new methods were introduced, 640 tons of potatoes were collected, and after the introduction of the new technology, 0 tons were collected.

A formula should always be accompanied by an explanation of what it calculates and the meaning of each of its variables. This formula calculates P, the periodic payment on a loan of n periods at interest rate i (compounded) per period. The principal amount of the loan is PV.

___

The same formula can also be used to calculate an annuity from which payment P is received at the end of each of n periods. The amount invested is PV and the interest rate per period (compounded per period) is i.

'n' typically represents the number of periods over which interest is calculated in a loan. However, symbols' intended meanings can change depending upon the context.

In most financial and mathematical formulas, the symbol 'n' typically represents the number of periods over which interest is calculated on a loan.

Steps

In all of these linear programming problems, the "objective function" is the function of the problem variables that you want to maximize or minimize. In order to write it, you need to understand what the problem variables are and how they relate to the objective. In each of these problems, you are told what x and y stand for and their relation to the objective.

When considering the constraints, you must consider how the problem variables relate to any limits imposed. As in problem 17, sometimes the limits are minima (must deliver at least ...). In problem 18, the limits are maxima (8 hours in a day; no more than 7 follow-ups).

So, first read and understand the problem statement and the relationships it is telling you. Then, do what the problem asks you to do. Sometimes that will involve finding a solution; sometimes not.

Often, you can use logic to help you understand whether your solution is reasonable. In the doctor problem (18), the doctor makes more money per hour doing follow-ups, so would probably want to maximize those (4, 7). However, doing that leaves a half-hour with zero revenue. That last hour is better spent seeing a new patient ($120) than seeing only one follow-up patient ($70).

Answer:

m∠LTE = 110

Step-by-step explanation:

1. add up all of the arcs.

2. all of the arcs equal 360

2x+3x+4x-8+x-12=360

3. Find x

4. angle LTE is equal to half of the sum of the intercepted arcs.

0.5(arc LE +GF)

5. plug in LE +GF with x

.5(76+144)

Answer:

m∠LTE = 110°

Step-by-step explanation:

We know that sum of all arcs of a circle is 360°

Therefore [tex]m(arcAL)+m(arcLG)+m(arcGF)+(mFE)=360[/tex]

Now we put the values of each arc

[tex](2x)+(3x)+(4x-8)+(x-12)=2x+3x+4x+x-8-12=10x-20=360[/tex]

10x = 360 + 20

10x = 380

[tex]x=\frac{380}{10}[/tex]

x = 38

Now from the theorem of intersecting chords in a circle

Measure of ∠LTE = [tex]\frac{1}{2}[m(arcEL)+m(arcGF)][/tex]

m(arc EL) = 2x = 2×38 = 76°

m(arc GF) = (4x - 8) = (4×38 - 8) = (152 - 8) = 144°

Now we can get the measure of ∠LTE

m∠LTE = [tex]\frac{1}{2}(76 + 144)=\frac{220}{2}=110[/tex]

Therefore m∠LTE = 110° is the answer.

The average rate of change of the log function f(x) = log x from 2 to 3 is approximately 0.18, calculated using the formula for average rate of change.

In mathematics, the average rate of change of a function between two points is defined as the change in the function's output divided by the change in its input. In this case, we want to find the average rate of change of f(x) = log x from 2 to 3.

The formula for this calculation is: (f(b) - f(a)) / (b - a). In this case, a = 2 and b = 3.

Step 1: Plug the values of a and b into the function log(x): f(2) = log(2) and f(3) = log(3).

Step 2: Subtract f(2) from f(3) and then divide by the difference between 2 and 3: (log(3) - log(2)) / (3 - 2) = (0.4771 - 0.3010) / 1 = 0.1761.

So, the average rate of change of the function f(x) = log x from 2 to 3 is approximately 0.18 when rounded to the nearest hundredth.

[tex]y=\frac{-255}{-15}[/tex]

[tex]y=15[/tex] equation (4)

step 3. Replace equation (4) in equation (3)

[tex]x=55-y[/tex]

[tex]x=55-15[/tex]

[tex]x=40[/tex]

We can conclude that the price of one advance ticket is $15 and the price of one same-day ticket is $40.

Answer:

y =  [4(x-3)]/3

Step-by-step explanation:

4x = 12+3y

3y = 4x-12

y =  [4(x-3)]/3

Best regards

To finding the valu of <a and <b

<a + 120 =180 [supplementary angle]

<a= 180-120

<a= 60

Again

<a+<b+60=180 [sum of interior angle of triangle is 180]

<b=180-60-<a

<b=180-120

<b=60

hope its helps u
