Answer:

Step-by-step explanation:

A. The data appears to be reported. The heights occur with roughly the same frequency.

A histogram is a graphical representation of a frequency distribution, where the x-axis represents the values of the data, and the y-axis represents the frequency of those values. If the heights are reported, the last digit of the heights should be randomly distributed and the frequency of each digit should be roughly the same, which is the case in a histogram with uniform distribution. This is in contrast to a histogram with non-uniform distribution, where certain heights occur a disproportionate number of times, which is more likely to happen when the heights are measured. Therefore, based on the information provided, it can be concluded that the data appears to be reported.

The value of x in the given equation will be 2/5

From the data,

We have to determine the value of x.

The given equation is: 18x-16=-12x-4

For determining the value of x, we will first shift the like terms on one side of the equation.

So, for solving the value of x we will shift the terms containing x and the constant on both sides of the equation.

So, shifting -12x from the right-hand side of the equation to the left-hand side of the equation,

We will get it as:

18x+12x = -4+16

30x=12

Now for solving the value of x we will shift x from the left side of the equation to the right side of the equation.

So, the value of x will be = 12/30 = 2/5

Step-by-step explanation:

The equation of the plane containing the two parallel lines v₁ = (0, 1, −8) t(6, 7, −5) and v₂ = (8, −1, 0) t(6, 7, −5) is 6x + 6y + 3z = 0.

What are parallel lines?

Parallel lines are coplanar infinite straight lines that do not intersect at any point in geometry. Parallel planes are planes that never meet in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance.

To find an equation for the plane containing the two parallel lines v₁ = (0, 1, −8) t(6, 7, −5) and v₂ = (8, −1, 0) t(6, 7, −5),

We use the equation of a line: v = v₀ + tv₁

where v₀ and v₁ are points on the line and t is a real number.

Substitute the given points in for v₀ and v₁: v = (0, 1, −8) + t(6, 7, −5)

This equation of the plane is Ax + By + Cz = D, where A, B, C, and D are constants to be determined.

Equate the components:

0x + 1y - 8z = D....(1)

6x + 7y - 5z = D...(2)

Now, we subtract equation (1) from (2) and we get

6x - 0x + 7y - 1y - 5z + 8z = 0

6x + 6y + 3z = 0

Hence, the equation of the plane containing the two parallel lines v₁ = (0, 1, −8) t(6, 7, −5) and v₂ = (8, −1, 0) t(6, 7, −5) is 6x + 6y + 3z = 0.

The planet's a) size has virtually no effect on its structure.

The size of a planet does not affect its internal structure significantly because the same physical laws govern the formation and evolution of all planets. However, the size of a planet does have some impact on its atmosphere, gravity, and surface features.

For example, smaller planets may have weaker gravity, which makes it easier for gases to escape their atmosphere. Conversely, larger planets may have stronger gravity, which can compress their atmosphere and create more extreme weather patterns.

Overall, a planet's structure is primarily determined by its mass, composition, and magnetic field, rather than its size.

The area of the region bounded between the graphs of\(y = -x^2 + 8x\) and \(y = x^2 + 2x\) is 9 square units.

To find the area of the region bounded between the graphs of\(y = -x^2 + 8x\)and\(y = x^2 + 2x\), we need to find the points of intersection of the two curves and then integrate the difference of the curves between these points.

First, we find the points of intersection by setting the two curves equal to each other:

\(-x^2 + 8x = x^2 + 2x\)

Simplifying and rearranging, we get:

\(2x^2 - 6x = 0\)

Factoring out 2x, we get:

\(2x(x - 3) = 0\)

So, \(x = 0 or x = 3.\)

Substituting these values of x in either of the two equations, we get the corresponding y values:

For\(x = 0, y = 0^2 + 2(0) = 0.\)

For\(x = 3, y = 3^2 + 2(3) = 15.\)

So, the points of intersection are (0, 0) and (3, 15).

Now, we can integrate the difference of the curves between these points to find the area.

\(A = ∫[0, 3] [(x^2 + 2x) - (-x^2 + 8x)] dx\)

Simplifying the integrand, we get:

\(A = ∫[0, 3] (2x^2 - 6x) dx\)

Integrating this expression, we get:

\(A = [(2/3) x^3 - 3x^2] [0, 3]\\A = [(2/3) (3)^3 - 3(3)^2] - [(2/3) (0)^3 - 3(0)^2]\\A = (18 - 27) - (0 - 0)\\A = -9\)

Therefore, the area of the region bounded between the graphs of\(y = -x^2 + 8x\) and\(y = x^2 + 2x\) is 9 square units.

Note that the area is a positive quantity even though the integrand was negative because the area is defined as the absolute value of the integral.

Question 23

Recall that a kite in geometry is any four sided figure where we have two different pairs of adjacent sides that are the same length.

We're told that PS = 4.5 and RS = 6. So this isn't an adjacent pair of congruent sides. But we can say that PS and PQ are one pair of adjacent congruent sides. That makes PQ to be 4.5 cm long.

Similarly, RS = RQ = 6 is the other pair of adjacent congruent sides. Notice that triangle PQR reflects over line PR to get triangle PSR.

See the diagram below.

The dimensions of the cylinder that minimize the surface area are:r ≈ 2.4817 cmh ≈ 3.1551 cm

The Lagrange Multipliers method is a method used to maximize or minimize a function subject to a constraint. It is typically used when there is a constraint on the function such that it cannot be optimized in the same way as an unconstrained function.

In this problem, we need to find the dimensions that minimize the surface area of a right circular cylinder while satisfying a constraint that the volume of the cylinder is 355 cubic cm.

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

S = 2πr² + 2πrh

The formula for the volume of a right circular cylinder is given by: V = πr²h

We can introduce a Lagrange multiplier λ to incorporate the constraint on the volume.

Thus, we need to minimize the function:

S = 2πr² + 2πrh + λ(πr²h - 355)

Taking the partial derivatives of S with respect to r, h, and λ, and setting them equal to zero, we get:

2πr + 2πhλ = 2πrh / rλ = πr²h - 355 / h

Taking the ratio of these two equations, we get:r / h = 2 / λ

This equation along with the constraint V = πr²h = 355 is used to find the dimensions that minimize the surface area.

Substituting the ratio r / h = 2 / λ in the equation V = 355, we get:

V = πr²h = π(λh)²h / 4 = 355

This simplifies to:

h³ = 1420 / πλ²Substituting this value of h in the equation r / h = 2 / λ, we get:

r = 2h / λ

Substituting the values of r and h in the formula for surface area S, we get:

S = 4πh² / λ + 4πh²λ + 4πh²λ² = 4πh²(1 / λ + λ + λ²)

We can now solve for the value of λ that minimizes S. Differentiating S with respect to λ, we get:

dS / dλ = 4πh²(-1 / λ² + 1 + 2λ)

Setting this equal to zero and solving for λ, we get:λ = (1 / 4)(-1 + sqrt(17))

This value of λ corresponds to the minimum surface area. Substituting this value of λ in the equations for r and h, we get:

r = 2h / λ = sqrt(68)(sqrt(17) - 1) / 3π ≈ 2.4817 cmh = (1420 / πλ²)^(1/3) = sqrt(1360 / sqrt(17)) / π^(1/3) ≈ 3.1551 cm

Therefore, the dimensions of the cylinder that minimize the surface area are:r ≈ 2.4817 cmh ≈ 3.1551 cm.

The degree sequence of a graph is the list of degrees of its vertices arranged in non-increasing order.

For a bipartite graph $K_{m,n}$ with $m$ vertices in the first partite set and $n$ vertices in the second partite set, every vertex in the first partite set is connected to all vertices in the second partite set and vice versa. Therefore, the degree of each vertex in the first partite set is $n$ and the degree of each vertex in the second partite set is $m$.

So, the degree sequence of the bipartite graph $K_{m,n}$ is $n,n,\ldots,n$ (repeated $m$ times) followed by $m,m,\ldots,m$ (repeated $n$ times). In other words, the degree sequence consists of two blocks, each of length $m+n$, where the first block contains the degree $n$ repeated $m$ times and the second block contains the degree $m$ repeated $n$ times.

The average of these two values is the final answer:

d = (7.5 + 3.38) / 2 = 5.44 km, rounded to the nearest kilometre, the distance is 5 km.

To determine the distance from station A to the balloon, you can use the tangent function. The formula is: d = h / tan(angle of elevation), where d is the distance, h is the height of the balloon, and angle of elevation is the angle between the line of sight from the observer to the balloon and the horizontal.

Using the first angle of elevation (57°), we can calculate the distance as:

d = h / tan(57°) = h / 1.998 = 15 / 1.998 = 7.5 km

Using the second angle of elevation (83°), we can calculate the distance as:

d = h / tan(83°) = h / 4.398 = 15 / 4.398 = 3.38 km

The average of these two values is the final answer:

d = (7.5 + 3.38) / 2 = 5.44 km, rounded to the nearest kilometre, the distance is 5 km.

The best estimate for her earnings is $1200

Step-by-step explanation:

Number of time spent babysitting each week = 21 hours = BBS

Number of time spent dog walking each week = 9 hours = DW

She earns $7.50 per hour for dog walking,

She earns $(7.50+1.50) = $9 for baby sitting,

There are 4 1/2 weeks = 9/2 weeks in July,

Now, for each week she earns 21(9) = $189 from baby sitting

and 9(7.5) = $67.5 from dog walking,

So, for the month of July, i.e. 9/2 weeks, she earns,

9/2(189) = $ 850.5 from baby sitting,

and (9/2)(67.5) = $303.75 from dog walking,

In total for the month, she earns,

850.5 + 303.75 = $1154.25

Hence the best estimate for her earnings is $1200
