If a stone is thrown upward with a speed of 110 feet per second from a height of 500 feet above the surface of a planet, the equation h = 500 + 110t - 5.5t² approximates the height of the stone, in feet, at t seconds. When will the stone be 698 feet above the planet's surface?​

Answer:

(C) (x)^2 + (y)^2 = 49.

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

In this case, the center of the circle is (0, 0), so h = 0 and k = 0. The radius of the circle is not given, but we can see that the equation must have a radius of 7 because the only terms involving x and y are squared and have coefficients of 1, which means they represent the distance from the center squared.

Therefore, the equation of the circle is:

(x - 0)^2 + (y - 0)^2 = 7^2

Simplifying, we get:

x^2 + y^2 = 49

So the correct answer is (C) (x)^2 + (y)^2 = 49.

Step-by-step explanation:

The upper limit of the confidence interval for the proportion of millennials that care about immigration is 0.20.

In order to find the upper limit of the confidence interval for the proportion of millennials that care about immigration,

we first need to calculate the confidence interval using the margin of error (MOE) and sample proportion.

The formula to find the confidence interval is given by:

Confidence Interval = Sample Proportion ± Margin of Error (MOE)

Where Sample Proportion = Poll Result / 100

Let's first find the Sample Proportion of millennials that care about immigration.

Sample Proportion = Poll Result / 100= 17 / 100= 0.17

Now let's calculate the confidence interval using the MOE.

Confidence Interval = Sample Proportion ± Margin of Error (MOE)

Upper Limit of Confidence Interval = Sample Proportion + MOE= 0.17 + 0.03= 0.20

Therefore, the upper limit of the confidence interval for the proportion of millennials that care about immigration is

Answer:

parallelogram

Step-by-step explanation:

opposite angles and sides are congruent

The possible whole-number values of 'a' that satisfy the triangle inequality are 2, 3, 4, 5, and 6.

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.

To create a triangle with sides a, b, and c, the sum of the lengths of any two sides must be greater than the length of the third side. This can be represented by the triangle inequality:

a + b > c

a + 6 > 7 (substituting the given values for b and c)

a > 1

b + c > a

6 + 7 > a

13 > a

a + c > b

a + 7 > 6

a > -1

Since the length of a cannot be negative, the inequality can be simplified to:

a > 1

Therefore, to create a triangle with side lengths of 7, 6, and some whole number value for a, a must be greater than 1. The possible whole-number values of 'a' that satisfy the triangle inequality are 2, 3, 4, 5, and 6.

The amount of work required to stretch the spring from 30.0 cm to 36.0 cm is 1.411 joules, which can be rounded to three decimal places.

According to Hooke's Law, the amount of work required to stretch or compress a spring by a certain amount is given by the formula:

W = (1/2) k (x2 - x1)²

where W is the work done (in joules), k is the spring constant (in newtons per meter), x1 is the initial displacement (in meters), and x2 is the final displacement (in meters).

In this case, the spring has a natural length of 30.0 cm, which is equivalent to 0.3 meters. To find the spring constant, we can use the fact that a 20.0-N force is required to keep it stretched to a length of 42.0 cm, which is equivalent to 0.42 meters.

Using Hooke's Law, we have

F = k (x2 - x1)20.0 N

= k (0.42 - 0.3) m

=> k = 80.0 N/m

Now we can use Hooke's Law again to find the amount of work required to stretch the spring from 30.0 cm to 36.0 cm, which is equivalent to 0.36 meters.

Using Hooke's Law, we have:

F = k (x2 - x1)W

= (1/2) k (x2 - x1)²W

= (1/2) (80.0 N/m) (0.36 - 0.3) m²W

= 1.411 J

Volume of the sphere is equal to two-third of the volume of a cylinder.

Volume is a mathematical concept that refers to the amount of space occupied by a three-dimensional object. It is expressed in cubic units, such as cubic meters or cubic centimeters, and can be calculated using a specific formula for each type of geometric shape.

A sphere is a perfectly round, three-dimensional object that looks like a ball. It has no edges or vertices and is symmetric around its center point. The formula for calculating the volume of a sphere is V = 4/3 πr³, where V is the volume, π is a mathematical constant approximately equal to 3.14, and r is the radius of the sphere.

True.

Assume that both the sphere's and cylinder's radius is r.

Considering that the base's diameter equals the cylinder's height

⇒h = 2r

Sphere radius = cylinder radius = r

Assuming the conditions are met, the sphere's volume:

=  [tex]\frac{2}{3}[/tex] × Volume of cylinder

= [tex]\frac{4}{3}[/tex]πr³= [tex]\frac{2}{3}[/tex] × πr² × 2r

The probability that the average size of the fish you caught is more than 14 inches is 0.1635 or 0.164

The size of bass caught in Strawberry Lake is normally distributed with a mean of 12 inches and a standard deviation of 5 inches.

If you catch 6 fish, the probability that the average size of the fish you caught is more than 14 inches is 0.202.

Here,

we need to find the probability that the average size of the fish you caught is more than 14 inches.

Let us denote the size of the bass caught in Strawberry Lake by X.

Then, X ~ N(μ = 12, σ = 5) represents the normal distribution of the size of bass caught in Strawberry Lake.

Let Y be the sample mean of 6 bass caught in the Strawberry Lake.

Then,

We know that Y ~ N(μ = 12, σ = 5/√6) represents the sampling distribution of the sample mean,

where σ = 5/√6

= 2.0412 (approx).

We are given that we have caught 6 fish.

Therefore, the sample size n = 6.

Then,

The probability that the average size of the fish you caught is more than 14 inches can be obtained as follows:

P(Y > 14) = P((Y - μ)/σ > (14 - μ)/σ)

= P(Z > (14 - 12)/2.0412)

= P(Z > 0.977)

= 1 - P(Z < 0.977) (as the standard normal distribution is a continuous distribution)

Using the standard normal distribution table, we get P(Z < 0.977) = 0.8365 (approx) Therefore, P(Y > 14) = 1 - P(Z < 0.977) = 1 - 0.8365 = 0.1635 (approx)

Therefore,

The probability that the average size of the fish you caught is more than 14 inches is 0.1635 or 0.164 (approx).

Answer: The general equation for a circle with center (h, k) and radius r is:

(x - h)^2 + (y - k)^2 = r^2

To find the equation of the circle that passes through the points (1, 1), (1, 3), and (9, 2), we can use the fact that the perpendicular bisectors of any two chords of a circle intersect at the center of the circle.

The midpoint and slope of the chord connecting (1, 1) and (1, 3) are:

Midpoint: ((1+1)/2, (1+3)/2) = (1, 2)

Slope: undefined (since x values are the same)

The perpendicular bisector of this chord passes through the midpoint (1, 2) and has a slope of 0. Therefore, its equation is:

y - 2 = 0

Simplifying this equation gives:

y = 2

Similarly, the midpoint and slope of the chord connecting (1, 1) and (9, 2) are:

Midpoint: ((1+9)/2, (1+2)/2) = (5, 1.5)

Slope: (2 - 1)/(9 - 1) = 1/8

The perpendicular bisector of this chord passes through the midpoint (5, 1.5) and has a slope of -8 (the negative reciprocal of the slope of the chord). Therefore, its equation is:

y - 1.5 = -8(x - 5)

Simplifying this equation gives:

y = -8x + 41.5

The intersection of the two perpendicular bisectors (y = 2 and y = -8x + 41.5) is the center of the circle. Solving for x gives:

2 = -8x + 41.5

8x = 39.5

x = 4.9375

Substituting x = 4.9375 into either equation for the perpendicular bisectors gives:

y = 2

Therefore, the center of the circle is (4.9375, 2) and the radius is the distance from the center to any of the three given points. For example, the distance from (4.9375, 2) to (1, 1) is:

r = sqrt((4.9375 - 1)^2 + (2 - 1)^2) = sqrt(24.9219) = 4.992

So the equation of the circle is:

(x - 4.9375)^2 + (y - 2)^2 = (4.992)^2

Expanding and simplifying this equation gives:

x^2 - 9.875x + 24.526 + y^2 - 4y + 0.076 = 24.916

Rearranging terms gives:

x^2 + y^2 - 9.875x - 4y - 0.34 = 0

So the general equation for the circle is:

x^2 + y^2 - 9.875x - 4y - 0.34 = 0

Step-by-step explanation:

The radius of the spherical boulder is half the diameter, so:

radius = 24 ft / 2 = 12 ft

The formula for the volume of a sphere is:

Substituting the given values, we get:

V = (4/3) x 3.14 x (12 ft)³

V = 7238.08 cubic feet

Rounding to the nearest whole number, we get:

V ≈ 7238 cubic feet

In a cube, a total of 12 lines can be formed.

It has 8 vertices and 12 edges. In geometry, a line is a straight geometric figure that extends indefinitely in both directions. The lines in a cube are the straight lines that connect two vertices or edges of the cube. When two points are connected with a line, it creates an edge. In a cube, there are 12 edges. Each edge is shared by two faces, and the edges are the line segments that make up the sides of the cube.

Thus, the number of lines that can be formed in a cube is 12. When two or more lines meet at a point, it is called a vertex. A cube has eight vertices or corners. When a line is drawn between any two vertices of a cube, it is called a diagonal. In a cube, there are 12 diagonals. A diagonal is a straight line segment that connects two non-adjacent vertices of a polygon. So, the number of lines that can be formed in a cube is 12, which includes the 12 edges.

We are told that P is currently rotated π/4 radians from the point directly to the right of O. This means that if we rotate the blade by an angle of a, P will end up at an angle of π/4 + a from the point directly to the right of O.

Answer: 7, and it occurs when x = 5 and y = 2

Step-by-step explanation:

1/5 x + 1/3 y = 1 (Equation 1)

x + y = ? (Equation 2)

We want to find the maximum value of x + y, so we need to maximize each of the variables x and y subject to the constraint given in Equation 1.

To solve for one of the variables, we can isolate it in terms of the other variable. Let's solve for y:

1/5 x + 1/3 y = 1

1/3 y = 1 - 1/5 x

y = 3(1 - 1/5 x)

Now we can substitute this expression for y into Equation 2:

x + y = x + 3(1 - 1/5 x)

Expanding the expression, we get:

x + y = x + 3 - 3/5 x

x + y = 3 + 2/5 x

So we can see that x + y is a linear function of x with slope 2/5 and y-intercept 3. To maximize x + y, we want to maximize x. However, x is a non-negative integer, so the maximum value of x occurs when x = 5 (since any larger value would result in a fraction in the expression for y).

Therefore, the maximum value of x + y is:

x + y = 3 + 2/5 x

x + y = 3 + 2/5 (5)

x + y = 5 + 2

x + y = 7

So the maximum value of the sum of these two non-negative integers is 7, and it occurs when x = 5 and y = 2.

c. The probability that the sample proportion is within 0.03 of the population proportion for a sample of 200 households is 0.7738.

a. The sampling distribution of the sample proportion, [tex]\bar p[/tex], can be approximated by a normal distribution with mean equal to the population proportion, p, and standard deviation equal to the square root of [tex][(p \times (1-p)) / n][/tex],

where n is the sample size.

Given that p = 0.17 and assuming a large enough sample size, we can use the formula to calculate the standard deviation of the sampling distribution:

Standard deviation = [tex]\sqrt{[(0.17 \times (1-0.17)) / n]}[/tex]

b. To find the probability that the sample proportion will be within a certain range of the population proportion, we need to calculate the z-score for the lower and upper bounds of that range and then find the area under the normal curve between those z-scores.

Let's say we want to find the probability that the sample proportion is within 0.03 of the population proportion. This means we want to find

P([tex]\bar p[/tex]- p ≤ 0.03) = P(([tex]\bar p[/tex]-- p) / [tex]\sqrt{[(p \times (1-p)) / n]}[/tex] ≤ 0.03 / [tex]\sqrt{[(p \times (1-p)) / n][/tex]

We can use the standard normal distribution and z-scores to find this probability:

[tex]z_1[/tex] = (0.03 / [tex]\sqrt{(0.17 \times (1-0.17)/n}[/tex])

[tex]z_2[/tex] = (-0.03 / [tex]\sqrt{(0.17 \times (1-0.17))/n}[/tex])

We can find the probability that the z-score is between [tex]z_1[/tex] and [tex]z_2[/tex]:

P([tex]z_1[/tex]≤ Z ≤ [tex]z_2[/tex]) = P(-0.541 ≤ Z ≤ 0.541) = 0.4101

c. To answer part (c), we need to specify the sample size. Let's say we are taking a sample of 200 households.

Using the formula for standard deviation of the sampling distribution from part (a), we get:

Standard deviation = [tex]\sqrt{(0.17 \times(1-0.17)) / 200}[/tex] = 0.034

Now we can repeat the same steps as in part (b) with this standard deviation:

[tex]z_1[/tex] = (0.03 / 0.034)

[tex]z_2[/tex] = (-0.03 / 0.034)

P([tex]z_1[/tex]≤ Z ≤ [tex]z_2[/tex]) = P(-0.882 ≤ Z ≤ 0.882) = 0.7738

The co-ordinates of Q' and R' when triangle PQR is translated to triangle P'Q'R' are (-3,3) and (-1,1), respectively.

A translation is a type of transformation where a shape is moved from one position to another.

However, the shape is not rotated, resized, or reflected in a translation.

Instead, it is moved in a straight line from one position to another.

A translation in a two-dimensional plane is specified by a vector, which specifies the distance and direction of the translation.

The co-ordinates of Q' and R' when triangle PQR is translated to triangle P'Q'R' are (-3,3) and (-1,1), respectively.

To determine these co-ordinates, we can use the following steps:

Determine the vector of the translation.

To do this, we find the difference between the corresponding vertices of the two triangles.

Here, we can take PQ as the base.

So, P'Q' = QRQR

= PQP' = P + (-1,2)

= (-2,3)Q'

= Q + (-1,2)

= (-3,3)R'

= R + (-1,2)

= (-1,1).
