Step-by-step explanation:

You can see that the only difference between the two graphs is that the red one is shifted up by 4 units. To accomplish this, simply add 4 to the parent function (which in this case is x²). Thus, the answer is just x²+4

Given an angle α in quadrant 4 with cos α = -7/25, we can use the half-angle formula for cosine to find the exact value of cos(α/2) as √(15)/10.

In trigonometry, the half-angle formula for cosine states that cos(α/2) = ±√((1+cos α)/2), where α is an angle and cos α is the cosine of that angle. The sign of the formula depends on the quadrant in which the angle α lies.

In this case, we are given that α is an angle in quadrant 4 and that cos α = -7/25. Since cosine is negative in quadrant 4, we know that the half-angle formula for cosine must be negative. Using the half-angle formula for cosine, we have cos(α/2) = -√((1+cos α)/2) = -√((1-7/25)/2) = -√(18/50) = -√(9/25) * √(2/2) = -3/5 * √2.

However, we can simplify this answer further by rationalizing the denominator. Multiplying both the numerator and denominator by √2, we get cos(α/2) = -3√2/10.

Therefore, the exact value of cos(α/2) is -3√2/10 or equivalently, √(15)/10 in simplified radical form.

In conclusion, given an angle α in quadrant 4 with cos α = -7/25, we can use the half-angle formula for cosine to find the exact value of cos(α/2) as √(15)/10.

Answer:

153°

Step-by-step explanation:

Angle EHG is a right angle, so it measures 90°.

The measures of angles EHF and FHG add to 90°.

m<EHF + m<FHG = 90°

m<FHG = 27°

m<EHF + 27° = 180°

m<EHF = 153°

The sorrect option: y - 4 = 5x - 10, is the equation of the line, in point-slope form.

The slope of the line;

Slope m = 5.

Passing points: (x1, y1) =  (-2, 4).

So, general equation of the line,

y - y1 = m(x - x1)

y - 4 = 5(x + 2)

y - 4 = 5x - 10

Step-by-step explanation:

Before the 3-for-2 split, Katelyn owns 140 shares of the stock that sells for $39 a share.

In a 3-for-2 split, each share is replaced with 1.5 new shares. This means that Katelyn's 140 shares will be replaced with 140 x 1.5 = 210 new shares.

To determine the new stock price after the split, we need to divide the old stock price by the split ratio (3/2):

New stock price = $39 / (3/2) = $26 per shareTherefore, after the 3-for-2 split, Katelyn will own 210 shares of the stock, and each share will be worth $26. The total value of her shares will be:

Total value = Number of shares x Price per shareTotal value = 210 x $26Total value = $5,460So Katelyn will own 210 shares worth $5,460 after the 3-for-2 split is announced.

Answer:

If the mean of four numbers is 7, we know that their sum is 7 * 4 = 28. We can use this information to find the last number. If the fourth number is x, we can write:

2 + 5 + 17 + x = 28

24 + x = 28

x = 4

The probability that the diameter of a selected ball bearing is between 143 and 144 millimeters, given a normal distribution with a mean diameter of 138 millimeters and a variance of 9. Therefore, the probability that the diameter of a selected ball bearing is between 143 and 144 millimeters is approximately 0.0247

To calculate the probability, we first need to standardize the values of 143 and 144 millimeters using the z-score formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

In this case, the mean (μ) is 138 millimeters and the variance (σ^2) is 9, so the standard deviation (σ) is the square root of the variance, which is √9 = 3.

For 143 millimeters:

z1 = (143 - 138) / 3 = 5 / 3 ≈ 1.6667

For 144 millimeters:

z2 = (144 - 138) / 3 = 6 / 3 = 2

Next, we need to use the standard normal distribution table or a calculator to find the probability associated with these z-scores. The probability between these two z-scores represents the probability of the diameter being between 143 and 144 millimeters.

Using the table or a calculator, we find that the cumulative probability corresponding to z1 = 1.6667 is approximately 0.9525, and the cumulative probability corresponding to z2 = 2 is approximately 0.9772.

To find the probability between 143 and 144 millimeters, we subtract the cumulative probability corresponding to z1 from the cumulative probability corresponding to z2:

P(143 < x < 144) = P(z1 < Z < z2) = P(z2) - P(z1) = 0.9772 - 0.9525 ≈ 0.0247

Therefore, the probability that the diameter of a selected ball bearing is between 143 and 144 millimeters is approximately 0.0247 (or 2.47% rounded to four decimal places).

The statement is True only for independent events and False otherwise. The statement "p (A ∩ B) = p(A). p(B)" is not always true for any two events A and B defined on a sample space S of an experiment.

This equation only holds true if A and B are independent events, meaning that the occurrence of one event does not affect the probability of the other event happening. In other words, p(A|B) = p(A) and p(B|A) = p(B).

If A and B are dependent events, meaning that the occurrence of one event affects the probability of the other event happening, then the equation does not hold true. In this case, the probability of A and B occurring together (p(A ∩ B)) would be less than the product of the probabilities of A and B occurring separately (p(A).p(B)).

Therefore, the statement is not always true and depends on whether A and B are independent or dependent events.

The average salary for accountants in Poland is $617.00.

To find the average salary for accountants in Poland, we can use the formula for a z-score and the given information. The formula for a z-score is:

z = (x - μ) / σ

where x is the value of the accountant's salary ($925.40), μ is the mean salary, σ is the standard deviation of the salary ($154.20), and z is the z-score (2.00).

Rearranging the formula, we can solve for the mean salary:

μ = x - zσ

Plugging in the given values, we get:

μ = $925.40 - (2.00)($154.20)

μ = $925.40 - $308.40

μ = $617.00

So, the average salary for accountants in Poland is $617.00.

The given equation solved for z is z = s/(r - 6c⁴)

From the questions, we are to solve the given equation for the specified value

The given equation is

s = zr - 6zc⁴

The specified value is z.

Thus, we are to solve for z.

Solving for z

s = zr - 6zc⁴

First, factor out z

s = z(r - 6c⁴)

Now, divide both sides by r - 6c⁴

s/(r - 6c⁴) = z(r - 6c⁴)/r - 6c⁴

s/(r - 6c⁴) = z

Step-by-step explanation:

$56 (her budget) divided by $8 (which is the cost per pound) will equal x.  Since we do not know the actual answer of the number of pounds she will buy due to the fact she will spend less than $56, which is also making her open to buying a total of $56.   Since the question is asking for the possible numbers of pounds she will buy, we will use the identity for pounds to be x.  We don't know the actual amount she will buy so the answer is x ≤ 7.  She will buy either less than or exactly 7 pounds of candy.

The ratio of the surface area of the larger cylinder to the surface area of the smaller cylinder is 4:3.

The ratio refers to the relative size of one quantity or value compared to another quantity or value.

Ratios are expressed in percentages, decimals, or fractions because they show proportional values compared one with another.

The surface area of a cylinder is given by the formula:

A = 2πrh+2πr²

Where A is the surface area, r is the radius, and h is the height.

Since only the heights of the two cylinders are given, we can determine the ratio of the surface area of the larger to the surface area of the smaller cylinder by comparing their heights.

Height of smaller cylinder = 15 inches

Height of larger cylinder = 20 inches

Ratio of the cylinders = 15 : 20

Answer:

60 mph

Step-by-step explanation:

Each way of the trip is 240 miles.

The round trip is 2 × 240 miles = 480 miles

The first half of the trip, 240 miles, was made at a speed of 30 mph.

s = d/t

st = d

t = d/s

t = 240 miles / 30 mph = 8 hours

The first part of the trip took 8 hours.

The entire round trip is 240 miles × 2 = 480 miles

The speed for the entire trip is 40 mph.

480 miles / 40 mph = 12 hours

12 hours - 8 hours = 4 hours

The return trip takes 4 hours.

The return trip is 240 miles.

s = d/t = 240 miles / 4 hours

s = 60 mph

Answer: 60 mph
