In this task, you’ll apply what you’ve learned to answer questions about a skateboard ramp that you and your friends are building for your community skate park. The ramp will lead up to a platform. You’ll be using a piece of wood that’s 3.5 meters long for the ramp, and the ramp’s angle of elevation will be 28°. Use this figure as a model to answer the questions that follow.

A diagram of a ramp leading to a platform. The ramp consists of the triangle ABC, of which the line BC is the left side of the platform. Angle A measures 28 degrees.

Find the horizontal distance from the bottom of the ramp to the bottom of the platform. Show your work, rounding to the nearest hundredth, if necessary.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

If you take a vertical line and place it on the graph, then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once. If so, then it is a vertical line.

If not, then it isn't one.

Step-by-step explanation:

The equation of the line that passes through the points (0,-2) and (3,2) is  4x-3y-6 = 0.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

In the given graph,

The points are (0,-2) and (3,2)

To find the equation of the line,

Find slope by using formula  m = (y₂-y₁)/(x₂-x₁)

m = (2-(-2))/(3-0)

m = 4/3

The equation of line is,

y-y₁ = m (x-x₁)

y-(-2) = 4/3(x-0)

y+2 = 4/3x

3y+6 = 4x

4x-3y-6 = 0

The required equation of line is 4x-3y-6 = 0.

The parametric equations for the tangent line to the curve at the point (2, 6, 1) are: x_tan(t) = 2 + 4t  ,  y_tan(t) = 6 + (3√2/2)t ,   z_tan(t) = 1 + 4e^2t

To find the parametric equations for the tangent line to the curve at the specified point (2, 6, 1), we need to find the derivatives of x(t), y(t), and z(t) with respect to t and evaluate them at the given point. Let's calculate:

Given parametric equations:

x(t) = t^2 + 1

y(t) = 6√t

z(t) = e^(t^2 - t)

Taking derivatives with respect to t:

x'(t) = 2t

y'(t) = 3/t^(1/2)

z'(t) = 2t*e^(t^2 - t)

Now, we can substitute t = 2 into the derivatives to find the slope of the tangent line at the point (2, 6, 1):

x'(2) = 2(2) = 4

y'(2) = 3/(2^(1/2)) = 3√2/2

z'(2) = 2(2)*e^(2^2 - 2) = 4e^2

So, the slope of the tangent line at the point (2, 6, 1) is:

m = (x'(2), y'(2), z'(2)) = (4, 3√2/2, 4e^2)

To obtain the parametric equations for the tangent line, we use the point-slope form of a line. Let's denote the parametric equations of the tangent line as x_tan(t), y_tan(t), and z_tan(t). Since the point (2, 6, 1) lies on the tangent line, we have:

x_tan(t) = 2 + 4t

y_tan(t) = 6 + (3√2/2)t

z_tan(t) = 1 + 4e^2t

Therefore, the parametric equations for the tangent line to the curve at the point (2, 6, 1) are:

x_tan(t) = 2 + 4t

y_tan(t) = 6 + (3√2/2)t

z_tan(t) = 1 + 4e^2t

Sean and his six companions will each receive 1/7 of the original action figures.

Let's assume Sean originally had x action figures. After donating some, he has 1/3 of them left, which is (1/3)x.

To find out how many action figures Sean has left, we can use the equation:

(1/3)x = x - y

where y is the number of action figures Sean donated.

Simplifying this equation, we get:

y = (2/3)x

Now, Sean wants to share his remaining action figures with 6 friends, so they will split the total number of action figures into 7 equal parts (Sean + 6 friends).

Therefore, each person will get 1/7th of the total number of action figures.

To find out what fraction of the original action figures each person will get, we need to divide the number of action figures each person will get by the original number of action figures (x):

1/7 = \(\frac{[(\frac{1}{3} )x - y]}{x}\)

Substituting y = (2/3)x, we get:

1/7 = \(\frac{[(\frac{1}{3} )x - (\frac{2}{3} )x]}{x}\)

1/7 = (1/3)

Therefore, each person will get 1/7th of the original number of action figures.

Main AnswerIn the study by Hoynes (2012), the population that is of interest to the researchers are families who receive Supplemental Nutrition Assistance Program (SNAP) or more commonly known as food stamps. The study examines the impact of the policy-driven change in economic resources available in utero and during childhood on the economic health of individuals in adulthood.

The sample that the study examines are 60,782 families over the time period of 1968 to 2009, which is subsequent to the introduction of the Food Stamp Program in 1961. The data links family background in early childhood to adult health and economic outcomes.The characteristics of the population that are of interest to the researchers are the impact of a positive and policy-driven change in economic resources available in utero and during childhood on the economic health of individuals in adulthood. Specifically, the researchers looked at the long-term effect of access to food stamps in childhood on the incidence of metabolic syndrome (obesity, high blood pressure, and diabetes) and an increase in economic self-sufficiency for women.

Based on the study, the researchers concluded that access to food stamps in childhood leads to a significant reduction in the incidence of metabolic syndrome and, for women, an increase in economic self-sufficiency. Hence, the results suggest substantial internal and external benefits of SNAP.

(i) Choose one of the n elements as the first element of the subset, then choose k − 1 elements from the remaining n − 1 elements. This can be done in nC1 * (n − 1)C(k − 1) ways.

(ii) The subset does not include the first element. This can be done in nCk ways. Now, we count the number of ways of choosing a subset with k elements from the set with n + 1 elements. This can be done in (n + 1)Ck ways. By the addition principle of counting, we add these two cases and get the identity (n + 1)Ck = nC(k−1) + nCk.b)

Let N be the number of objects and k be the number of boxes. Let q be the quotient when N is divided by k. If N is divisible by k, then each box will contain exactly q objects.

Answer:

25%

Step-by-step explanation:

As the given situation the parameters are below:-

Cost of each box = 3 pounds

Amount of cereal in each box = 160 g

now,

160 g of cereal = 100%

and

25% of 1 box of cereal = 25% of 160 g which is

\(= \frac{25}{100} \times 160 g= 40 g\)

As per the question,  it is mention that Jane need her idea to give the equal value of amount as Tim's idea, provided

160 g of cereal costs 3 pounds

and

1 g of cereal will cost

=  \(\frac{3}{60}\ pounds\)

40 g of cereal will cost \(40\times \frac{3}{160} = \frac{3}{4}\ pounds\)

So, the percentage of \(\frac{3}{4}\) the pound is of 3 pounds is 3 ÷ 4 ÷ 3 × 100

= 25%

Therefore as the situation, Jane need to decline the amount by 25% for the same amount as Tim's idea.

At the instant when the bottom of the ladder is 6 ft from the wall and sliding away at a rate of 1 ft/sec, the top of the ladder is sliding down the wall at a rate of -3/4 ft/sec.

Let's denote the distance between the top of the ladder and the ground as y and the distance between the bottom of the ladder and the wall as x. We are given that dx/dt = 1 ft/sec and want to find dy/dt when x = 6 ft.

According to the Pythagorean theorem, we have the equation

\(x^2\) + \(y^2\) = \(10^2\).

Differentiating both sides with respect to time (t), we get:

2x(dx/dt) + 2y(dy/dt) = 0.

Substituting the given values, we have:

2(6)(1) + 2y(dy/dt) = 0.

Simplifying the equation, we get:

12 + 2y(dy/dt) = 0.

Now, we can solve for dy/dt:

2y(dy/dt) = -12,

dy/dt = -6/y.

To find dy/dt when x = 6 ft, we substitute x = 6 into the equation:

dy/dt = -6/y = -6/8 = -3/4 ft/sec.

Therefore, the top of the ladder is sliding down the wall at a rate of -3/4 ft/sec when the bottom of the ladder is 6 ft from the wall.

Modifying Above p with caret minus Upper E less than p less than ModifyingAbove p with caret plus Upper E

where p is the point estimate, and Upper E is the margin of error.


To express the confidence interval (0.008, 0.096) in the form of ModifyingAbove p with caret minus Upper E less than p less than ModifyingAbove p with caret plus Upper E, we first need to find the point estimate (p) and the margin of error (Upper E).

The point estimate is the midpoint of the interval, which is:

p = (0.008 + 0.096) / 2 = 0.052

The margin of error is half the width of the interval, which is:

Upper E = (0.096 - 0.008) / 2 = 0.044

Therefore, the confidence interval can be expressed as:

ModifyingAbove 0.052 with caret minus 0.044 less than p less than ModifyingAbove 0.052 with caret plus 0.044

This means that we are 95% confident that the true population proportion (p) falls within the range of 0.008 to 0.096.

the confidence interval (0.008, 0.096) can be expressed in the form of Modifying Above p with caret minus Upper E less than p less than Modifying Above p with caret plus Upper E as Modifying Above 0.052 with caret minus 0.044 less than p less than Modifying Above 0.052 with caret plus 0.044.
