Answer:

the first answer is A y^2=8x

Step-by-step explanation:

The equation of a parabola that opens to the right with vertex at the origin (0,0) and has a focal width of 8 is y^2 = 8x. This follows from the equation of a parabola in standard form, y^2 = 4ax, where 4a equals the focal width.

The equation of a parabola in standard form is either y^2=4ax or x^2=4ay, depending on its orientation. The vertex is at the origin (0,0). A parabola that opens to the right or left has the form y^2 = 4ax, and one that opens upward or downward has the form x^2 = 4ay. Given that your parabola opens to the right and has a focal width of 8, it would utilize the first form. The focal width is the absolute value of 4a. Thus, for your parabola, 4a is equal to the focal width, which is 8. Therefore, a = 8/4 = 2. Hence, the equation of the parabola with vertex at the origin that opens to the right and has a focal width of 8 is y^2 = 8x.

Answer: 151.1

Step-by-step explanation:

First, you would add all the heights together (153+150+151+152=606)

Then you would divide 606 by the number of numbers in the data set in this case the number of family members which is (606 divided by 4= 151.1)

Answer:

151.5

Step-by-step explanation:

First of all, what is the mean in a set of numbers?

To find the average of these numbers, we'll add all of the numbers and divide it by 4, the number of actual terms, in the set.

(153 + 150 + 151 + 152) / 4 = 151.5

Answer:

The object first reaches 72 feet after 1.5 seconds; it is this height again after 2.5 seconds.

Step-by-step explanation:

To find the amount of time it takes to reach 72 feet, we solve the equation

72 = -16t² + 64t + 12

To solve this, we will set it equal to 0 by subtracting 72 from each side:

72-72 = -16t² + 64t + 12 - 72

0 = -16t² + 64t - 60

Next we will use the quadratic formula to solve this:

By setting up and solving the required quadratic equation, it is determined that an object propelled from a height of 12 feet with an initial velocity of 64 feet per second will take 3.75 seconds to reach a height of 72 feet.

The height h of the object is given by the equation h = -16t^2 + 64t + 12. We need to solve for time t, where the height h is 72 feet. By setting the equation equal to 72, we get 72 = -16t^2 + 64t + 12.

Moving -16t^2 and 64t to the other side, we get 16t^2 - 64t + (72 - 12) = 0. This simplifies to 16t^2 - 64t + 60 = 0. Divide every term in the equation by four to get: 4t^2 - 16t + 15 = 0. This equation must now be solved using the quadratic formula: t = [-b +/- sqrt(b^2 - 4ac)] / (2a).

Plugging in the values a=4, b=-16, and c=15, we get two possible solutions: t = 1 and t = 3.75 seconds. As the object is propelled up and comes down, we take the larger value, t=3.75 seconds, because that's the actual duration for the object to reach the height of 72 feet.

Answer:

BC = 8

Step-by-step explanation:

These are similar shapes, so they multiply out to the same ratio.

Seeing that 10 * 1.5 = 15, BC * 1.5 should equal 12.

All we do is divide 1.5 from both sides to get 8.

Then, plug it back into the equation to check and it works.

Answer:  x = 8

Step-by-step explanation:

You can solve by setting up the proportions of the corresponding sides of the pentagon and then solve for x (the value of BC).  

So, IJ/DE values are 15/10 and are set equal to GH/x (x represents the value of BC; the value you are solving for).  Hint: It may be helpful for you to draw a diagram of the two pentagons and label them with the letters and values provided in the problem.  This will help you to set up your proportion problem accurately.

To solve you can cross multiply to find the value of x.

15/10 = 12/x

15x = 12 * 10

15x = 120

x = 120/15

x = 8

Answer:

$18.30

Step-by-step explanation:

First, you can figure out the cost per golf ball by dividing the price by the number of golf balls. If 6 balls = 7.32, then 1 ball = 7.32/6, or 1.22. Now you can multiply this by the number of balls in the box to find out the price: 1.22 * 15 = 18.30.

Another way to solve this is to set up a ratio of balls / price:

(x is the unknown price)

[tex]\frac{6}{7.32} =\frac{15}{x}[/tex]

Now, cross-multiplying, you find that 6x = 7.32 * 15, or 6x = 109.8. Dividing both sides by 6, you get x=18.30.

Step-by-step explanation:

To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:

 [tex]LA=r*L*\pi[/tex]

where r is the radius but L is the slant height.

As you can see in the figure attached:

[tex]r=5[/tex]

But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):

[tex]L=\sqrt{11^2+5^2}=\sqrt{146}[/tex]

Substitute into the formula, then:

 [tex]LA=(5)(\sqrt{146})\pi=5\pi\ \sqrt{146[/tex]units²

Answer:

The correct answer is 5√146π  square units

Step-by-step explanation:

From the figure we can see a cone

Points to remember

Lateral surface area of cone = πrl

r - Radius of cone

l - Slant height of cone

To find the slant height

From figure we get,

r = 5 units and height = 11 units

Slant height² = radius² + height² =  5² + 11² = 25 + 121 = 146

Slant height = √146 units

To find the lateral area

lateral area = πrl =  π * 5 * √146  = 5√146π  square units

The correct answer is 5√146π  square units

Dylan earns $17.50 per hour for 4 hours, yielding a total income of $70. After deducting 15% of his total earnings ($10.50) for income taxes, Dylan's earnings reduce to $59.50.

To answer this question, we first need to calculate Dylan's total earnings before taxes. He earned $17.50 per hour for 4 hours, so his total earnings would be 4 hours * $17.50/hour = $70.

Next, we determine the amount of income tax. Dylan's income tax rate is 15%, so he would pay 15% of his total earnings in taxes: 15/100 * $70 = $10.50 in taxes.

Finally, we calculate Dylan's net earnings after tax by subtracting the tax amount from his total earnings: $70 - $10.50 = $59.50. Therefore, Dylan will earn $59.50 after taxes for 4 hours of work.

Answer: 10,472.36 feet

Step-by-step explanation:

- Observe the diagram attached (It is not drawn to scale).

- Calculate the height between helicopter and airplane (h), as following:

[tex]tan\alpha=\frac{opposite}{adjacent}\\\\tan(71\°)=\frac{h}{3,055}[/tex]

Solve for h:

[tex]h=(3,055)(tan(71\°))\\h=8,872.36ft[/tex]

- Therefore, the altitude of the plane is:

[tex]altitude=1,600ft+8,872.36ft\\altitude=10,472.36ft[/tex]

You can use the tangent ratio to find the airplane's altitude.

The altitude of the airplane in the given condition is 10,471.72 ft

You look straight parallel to ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal to the point where you stopped your head is called angle of elevation.

In a right angled triangle(triangle with one of the angles as right angle which is 90 degrees), seeing from perspective of an angle, the tangent ratio is the ratio of the side opposite to that angle and the side which is perpendicular to that opposite side.

Refer to the attached figure.
The altitude of the plane is the length of the line segment CE.

We have the rectangle ABDE, thus, AD = BE in terms of length.

(remember that |AB| means length of line segment AB).

Thus,
|CE| = |CB| + |BE| = |CB| + 1600 ft

Using the tangent ratio for triangle ABC from angle A, we get:

[tex]tan(A) = \dfrac{|CB|}{|AB|} = \dfrac{|CB|}{3055}\\\\tan(71) \approx 2.904 = \dfrac{|CB|}{3055}\\\\|CB| = 3055 \times 2.904 = 8.871.72 \: \rm ft[/tex]

Thus,

|CE| = |CB| + 1600  = 8871.72 + 1600 = 10,471.72 ft.

The value of y, when x = 2 1/3 in a direct variation scenario where y = kx (k being the constant of variation), is approximately 233.3.

In the given problem, the value of y varies directly with x. This means there's a constant of variation, k, such that y = kx. We can find k by plugging in the initial given values, x=1/4 and y=25, into this equation, which gives us k = y/x = 25/(1/4) = 100.

Now that we know k, we can calculate the value of y when x = 2 1/3 using the same equation. Here, y = kx = 100 * 2 1/3 = 100 * 7/3 = 700/3 = 233.3 recurring.

So, when x = 2 1/3, y is approximately 233.3.

Answer:

1:  z = 1.96

2:  t = 2.552

Step-by-step explanation:

1:  When you don't know the population standard deviation and the sample size is large, you can still use a z test because many large samples are relatively normally distributed.  A 95% confidence interval uses a z-score of 1.96

2.  We are told that n < 30, so we use t distribution.  Use the degrees of freedom, which is one less than the population, and the column that has 0.02 in the area of 2 tails.

In constructing a confidence interval, if the standard deviation is unknown and the population appears skewed, we typically use the t-distribution. However, without enough information given, the answer to the first problem tends towards 'Neither normal nor t distribution applies'. For the second problem, the standard deviation is given and the population appears normally distributed, hence answer is 'zα/2 = 2.33' from the z-table.

The relevant subject matter here is Statistics, specifically, confidence intervals. The construction of a confidence interval depends on the knowledge of the standard deviation and whether the population is normally distributed or not.

For the first problem, since the standard deviation (σ) is unknown and the population appears to be skewed, student's t-distribution applies here. This would involve using tα/2 with degree of freedom (n-1) in place of the unavailable standard deviation. However, without enough data provided in the question, it is difficult to correctly compute tα/2. The answer therefore likely tends towards option E: 'Neither the normal nor the t distribution applies'.

For the second problem, the standard deviation (σ) is given and the population appears to be normally distributed. This suggests the normal distribution applies, hence you would compute zα/2, the critical value for the z-score at a 98% confidence level. Referring to a standard z-table at a 98% confidence level gives a z-score of approximately 2.33. So, the answer for this scenario is A: zα/2 = 2.33.

To find the measure of angle z, subtract the measures of angles x and y from 180°. Therefore, angle z = 180° - 30° - 35° = 115°.

The subject of the question is geometry, specifically dealing with the measures of angles. Without more context, it's difficult to provide an exact answer. However, if angles x, y, and z form a triangle, then the measure of angle z can be found using the property that the sum of all angles in a triangle is 180°.

To find the measure of angle z, you need to recall that the sum of the angles in a triangle is always 180°. So, you can start by finding the measure of angle z by subtracting the measures of angles x and y from 180°.
