Answer:

the second choice

The value of the constant k that makes the function continuous everywhere is \(k = \frac{7}{48}$\)

For the function to be continuous everywhere, we need to ensure that the limit of f(x) as x approaches 7 from the left is equal to the limit of f(x) as x approaches 7 from the right.

From the left, we have:

\($$\lim_{x\to7^-}f(x) = \lim_{x\to7^-}kx^2 = k(7)^2 = 49k$$\)

From the right, we have:

\($$\lim_{x\to7^+}f(x) = \lim_{x\to7^+}(x+k) = 7+k$$\)

For the function to be continuous at x=7, we need:

\($$\lim_{x\to7^-}f(x) = \lim_{x\to7^+}f(x)$$\)

Therefore, we need:

\($$49k = 7 + k$$\)

Solving for k:

\($$49k - k = 7$$\)

\($$48k = 7$$\)

\($k = \frac{7}{48}$$\)

Therefore, the value of the constant k that makes the function continuous everywhere is \(k = \frac{7}{48}$\)

Step-by-step explanation:

Because it would make the reader pause and it's just adding more information to the text giving the reader more understanding

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Answer:

The answer is B. \(\frac{6}{5}\).

Step-by-step explanation:

In order to solve for the length of the altitude of the smaller pyramid, start by writing the length of the altitudes and the length of the pyramids in a proportion. The proportion should look like \(\frac{3}{5}\) = \(\frac{x}{2}\) because each number has to correspond with its similar number.

Next, cross multiply both fractions to get an equation, which will look like   5x=(3)(2). Simplify the equation, and now it will look like 5x=6.

Then, divide both sides by 5, and the final answer will be \(\frac{6}{5}\).

If the production is increased by 10%, the new production levels for sport utility vehicles and pickup trucks are:

Factory 1: 110 sport utility vehicles

Factory 2: 99 sport utility vehicles

Factory 3: 77 sport utility vehicles, 66 pickup trucks

Factory 4: 33 sport utility vehicles, 66 pickup trucks

To find the production levels if production is increased by 10%, we need to multiply each entry of the matrix by 1.1:

A' = 1.1A = | 110 99 77 33 || 44 22 66 66 |

The matrix A' represents the new production levels. The entry in the first row and first column of A' (110) represents the number of sport utility vehicles produced at the first factory after the 10% increase in production. Similarly, the entry in the second row and third column of A' (66) represents the number of pickup trucks produced at the third factory after the 10% increase in production.

Answer:

0.0668 = 6.68% probability a randomly selected year will have an average snowfall above 200 inches.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a average of 170 inches, and a standard deviation of 20 inches.

This means that \(\mu = 170, \sigma = 20\)

What is the probability a randomly selected year will have an average snowfall above 200 inches?

This is 1 subtracted by the p-value of Z when X = 200. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{200 - 170}{20}\)

\(Z = 1.5\)

\(Z = 1.5\) has a p-value of 0.9332.

1 - 0.9332 = 0.0668

0.0668 = 6.68% probability a randomly selected year will have an average snowfall above 200 inches.

Answer:

29 degrees

Step-by-step explanation:

Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees

When 2 lines are congruent, it means the lines have an equal or the same length. The length of LJ is 32 units

Given that:

\(LK = 7x - 10\)

\(KN = x + 3\)

\(MN = 9x - 11\)

\(KJ = 28\)

First, we calculate MK

\(MK = MN - KN\)

So, we have:

\(MK = 9x - 11 - (x + 3)\)

Open bracket

\(MK = 9x - 11 - x - 3\)

Collect like terms

\(MK = 9x - x - 11 - 3\)

\(MK = 9x - 14\)

Given that: \(LK = MK\)

This gives:

\(7x -10 = 9x - 14\)

Collect like terms

\(9x - 7x = 14-10\)

\(2x =4\)

Divide both sides by 2

\(x =2\)

The length of LJ is:

\(LJ = LK + KJ\)

This gives:

\(LJ = 7x -10 + 28\)

Substitute 2 for x

\(LJ = 7 \times 2 -10 + 28\)

\(LJ = 14 -10 + 28\)

\(LJ = 32\)

Hence, the length of LJ is 32 units

step-by-step explanation

Answer:

It fr said "NAHHHHH" and changed the number

The expression y = 7/12 x - 4/3 will be the required quation of the line in slope-intercept form.

A line is defined as the shortest distance between two points. The equation of a line in point-slope form is expressed according to the equation:

y - y₁ = m(x - x₁)

where:

m is the slope

(x₁, y₁) is any point on the line.

Given the following parameters

Slope = 7/12

Point = (4, 1)

Substitute into the equation

y - y₁ = m(x - x₁)

y - 1 = 7/12(x - 4)

Write in slope-intercept form:

y - 1 = 7/12(x - 4)

12(y - 1) = 7(x - 4)

12y - 12 = 7x - 28

12y = 7x - 28 + 12

12y = 7x - 16

y = 7/12 x - 16/12

y = 7/12 x - 4/3

Hence the required equation of the line in slope-intercept form is y = 7/12 x - 4/3

When substituting y = 11 into the equation y = 1/2(x) - 25, we find that x = 72, confirming that (23.5, 11) is a valid point of intersection.

Given that x is 23.5, it is required to prove that it is an intersection point for the equation y = 1/2(x) - 25 when y is equal to 11.

The equation is given as y = 1/2(x) - 25

When y = 11, we can substitute the value of y in the equation to obtain 11 = 1/2(x) - 25

This can be simplified as 11 + 25 = 1/2(x)36 = 1/2(x)

On solving, x = 72Thus, when y is equal to 11 and x is equal to 72, the given point of intersection is valid.

Therefore, it can be concluded that x = 23.5 is a point of intersection for the equation y = 1/2(x) - 25 when y is equal to 11.

In summary, when given an equation with two variables, we can find the point of intersection by setting one of the variables to a given value and solving for the other variable. In this case, when y is equal to 11, we can solve for x and obtain the point of intersection as (72,11).
