Explain how to solve the given equation for "x".

Answer:

x=6 and x=−5.

Step-by-step explanation:

A. To calculate the monthly payment, we can use the formula for a fixed-rate mortgage:

M = P * (r*(1+r)^n) / ((1+r)^n - 1)

where:

M = monthly payment

P = principal (amount borrowed) = $213,000

r = monthly interest rate = APR / 12 = 0.0375 / 12 = 0.003125

n = total number of payments = 30 years * 12 months/year = 360

Plugging in these values, we get:

M = 213000 * (0.003125*(1+0.003125)^360) / ((1+0.003125)^360 - 1)

M ≈ $988.32

So the monthly payment, rounded to the nearest 10th, is $988.30.

B. The total amount paid over the 30-year period would be the monthly payment multiplied by the total number of payments:

Total = M * n

Total = $988.30 * 360

Total = $355,788.00

So the total amount paid over 30 years would be $355,788.00.

C. To calculate the total interest paid over the 30-year period, we can subtract the principal from the total amount paid:

Total Interest = Total - P

Total Interest = $355,788.00 - $213,000

Total Interest = $142,788.00

So the total interest paid over the 30-year period would be $142,788.00.

The probability that Betty is first in line or Mary is last in line is (n^2 - n - 1)/n(n-1), as a function of n.

We can approach this problem by considering the probability of the complementary event, i.e., the probability that neither Betty is first in line nor Mary is last in line, and then subtracting this probability from 1 to get the probability we want.

The total number of ways the n kids can line up is n!, since there are n choices for the first person in line, n-1 choices for the second person, and so on down to 1 choice for the last person.

The number of ways in which neither Betty is first in line nor Mary is last in line is (n-2)!, since there are (n-2) choices for the first person in line (excluding Betty and Mary), (n-3) choices for the second person, and so on down to 1 choice for the second-to-last person.

Therefore, the probability that neither Betty is first in line nor Mary is last in line is

[(n-2)! / n!] = 1/n(n-1)

The probability we want is

1 - 1/n(n-1) = (n^2 - n - 1)/n(n-1)

As a result, 2x + 10 is the expression that describes how long Malik will cook the sirloin for if the asparagus grills for x minutes.

So, 1+1 is a straightforward illustration of a statement. This expression has one action, two constant elements, and (addition). Another illustration is x3.

Let's start by using the given information to create expressions for each item:

Let's call the time it takes to grill the fish "f". Then, according to the problem, Malik grills the steak for "f + 10" minutes.

Grilling time for the seafood is double that of the vegetables. Thus, if it requires "x" minutes to grill asparagus, "2X" minutes are needed to grill salmon.

For "x + 1" minutes, and this is one minute more than he roasts the asparagus, Malik cooks the tomatoes that have been cut in half.

Using these expressions, we can create an equation for the time it takes to grill the steak:

Time to grill steak = Time to grill fish + 10

(f + 10) = 2x + 10

Therefore, if the asparagus cooks for x minutes, the phrase that denotes how long Malik will grill the sirloin is:

Vertical angles are a pair of opposite angles formed by two intersecting lines. Vertical angles are congruent, meaning they have the same measure.

For example, if two lines intersect and form four angles, the two angles that are opposite each other  are vertical angles.

Adjacent angles are two angles that have a common vertex and a common side but do not overlap.

In other words, they share a ray or line segment, but they don't share any interior points.

Adjacent angles may or may not be congruent, depending on their measurement.

For example, if two angles are next to each other and share a vertex and a side, they are adjacent angles.

  7. shifted right 8 units

  8. shifted left 4 and up 12 units

  9. shifted up 8 units

Step-by-step explanation:

You want to compare the given functions with p(x) = a(x -h)² +k and tell the value and effect of a, h, and k on the vertex.

In the equation for p(x) above, the value 'a' represents a vertical scale factor. It expands the graph vertically by the factor 'a'. If a < 0, the graph is reflected across the x-axis.

The values 'h' and 'k' in the equation for p(x) represent a right shift of the graph by 'h' units and a shift up by 'k' units. That is, the graph is translated by (h, k).

We have h = 8. The graph is shifted right 8 units.

We have (h, k) = (-4, 12). The graph is shifted left 4 units and up 12 units.

The values of the transformation parameters are a = -1/2 and k = 8. The vertical compression and reflection do not affect the vertex. The vertex is shifted up 8 units.

Probability is a measure of how likely an event is to occur. Many events are impossible to forecast with absolute accuracy. We can only anticipate the possibility of an event occurring, i.e. how probable they are to occur, using it. Probability can range from 0 to 1, with 0 indicating an impossible event and 1 indicating a certain event. The probability of all events in a sample space equals one.

According to the given information:

The experimental probability = [tex]\frac{Number of times an event occur}{ Total number of trials}[/tex]

You can expect 95% of your customers to stay in your store between range of  39.7 minutes and 49.9 minutes.

To determine the range in which 95% of your customers would stay in your store, we will use the properties of a normally distributed data set with a mean of 44.8 minutes and a standard deviation of 2.6 minutes.
Identify the mean and standard deviation.
The mean is 44.8 minutes, and the standard deviation is 2.6 minutes.
Determine the z-score for a 95% confidence interval.
A 95% confidence interval corresponds to a z-score of 1.96. This means that 95% of the data lies within 1.96 standard deviations from the mean.
Calculate the range using the z-score, mean, and standard deviation.
To find the lower and upper limits of the range, we will multiply the standard deviation (2.6 minutes) by the z-score (1.96) and then subtract or add the result to the mean (44.8 minutes).
Lower limit: Mean - (Z-score × Standard deviation)
44.8 - (1.96 × 2.6) = 44.8 - 5.096 ≈ 39.7 minutes
Upper limit: Mean + (Z-score × Standard deviation)

Now we can apply the binomial distribution formula, to calculate the probability as follows,

P = (3 choose 2) × (2/14)² × (12/14)

P = (3! / (2! × 1!)) × (2/14)² × (12/14)

A cone and a plane perpendicular to its side cross to create a symmetrical open plane curve known as a parabola1. It is a U-shaped curve whose vertex and axis of symmetry characterise it. The line dividing the parabola into its two mirror counterparts is known as the axis of symmetry. The parabola's vertex is where the axis of symmetry intersects it.

A parabola's vertex is represented by the equation y = a(x - h)²+ k, where (h,k) represents the vertex. We may utilise the vertex version of the equation and substitute the values of h, k, and the x and y coordinates of the point to determine the equation of a parabola that passes through a particular point and has a certain vertex.

B.  Here, the vertex is (1, 4), and the point (5,-4). In the vertex form equation, we may therefore substitute h=1, k=4, x=5, and y=-4 to obtain:

By answering the presented question, we may conclude that Therefore, Pythagorean the length of the third side of the triangle is [tex]2/\sqrt(5)[/tex]and the height is 4/5.

The Pythagorean theorem is a fundamental mathematical principle that describes the connection between the sides of a right triangle. It asserts that the sum of the squares of the other two sides' lengths equals the square of the hypotenuse's length (the side opposite the right angle). The mathematical theorem is as follows: c2 = a2 + b2 Where "c" denotes the hypotenuse length and "a" and "b" indicate the lengths of the other two sides, known as the legs.

Let's use the formula for the area of a triangle:

[tex]A = 1/2 * b * h2/5 = 1/2 * (6/5) * h\\h = 4/5\\a^2 = (6/5)^2 - (4/5)^2\\a^2 = 36/25 - 16/25\\a^2 = 20/25\\a^2 = 4/5\\[/tex]

To make the larger sculpture with each linear dimension 75% greater, the artist needs to use 265.625% or 3.65625 times more clay than the original sculpture.

Let's assume that the original sculpture is a cube with side length x cm. Therefore, its volume would be x³ cm³.

To make the larger sculpture, each linear dimension needs to be increased by 75%, which means that each side length will become 1.75x cm. Thus, the new volume of the sculpture will be (1.75x)³ = 5.378125 x³ cm³.

To find the amount of clay required to make the larger sculpture, we need to find the ratio of the new volume to the original volume (5.378125 x³ cm³) / (x³ cm³) = 5.378125

This means that the artist needs to use 5.378125 times more clay than the original amount used to make the larger sculpture.

Therefore, to find the actual amount of clay needed, we multiply the original amount of clay by 5.378125: n cm³ x 5.378125 = 5.378125n cm³

So, the artist needs to use 3.65625 or 265.625% times more clay than the original sculpture to make the larger sculpture with each linear dimension 75% greater.
