Marisa was tracking the diving speed of a bird. The average speed was 108 miles per hour. That means in one hour, the bird would travel 108 miles at that speed. However, these dives last far less than an hour, so Marisa needs to convert this to feet per second

Answers

By a change of units, we will get that 108 mi/h = 158.4 ft/s

Here we want to transform 108 mi/h to feet per second.

Then we will use two relations:

1 mi = 5,280 ft1 h = 3,600 s

Then we can just transform as:

108mi/h = (108*5,280 ft)/h = 570,240 ft/h

570,240 ft/h = 570,240 ft/(3,600 s) = 158.4 ft/s

So we have:

108 mi/h = 158.4 ft/s

Let (-3, 4) be a point on the terminal side of 0. Find the exact values of sin 0, csc 0, and cot 0.

Answers

Therefore, sin θ = 4/5, csc θ = 5/4, and cot θ = -3/4 using trigonometric ratio.

Trigonometric ratio calculation.

We know that the point (-3, 4) is on the terminal side of the angle θ, and we can use the Pythagorean theorem to find the value of the hypotenuse:

r² = x² + y²

r² = (-3)² + 4²

r² = 9 + 16

r² = 25

r = 5

Now we can find the values of sin θ, csc θ, and cot θ:

sin θ = y/r = 4/5

csc θ = r/y = 5/4

cot θ = x/y = -3/4

Therefore, sin θ = 4/5, csc θ = 5/4, and cot θ = -3/4.

After 1 year in busines, NetPix has 250 subscribers. They now expect to triple their number of subscribers each year. At that rate, how many subscribers would they have after 10 years in business?

Answers

Using the rate of the exponential growth to calculate the exponential function, the number of subscribers after 10 years is 3446

What is an Exponential Function

An exponential function is a function in which the variable appears in an exponent. It is of the form f(x) = aˣ, where a is a constant and x is the independent variable. The graph of an exponential function is a curve that increases or decreases at an increasing rate.

To solve this problem, we have to find the rate and then calculate the number subscribers after 10 years.

In a given exponential function;

A = P(1 + x)ⁿ

Since this is an exponential growth, we can calculate the rate as;

1 year = 250 subscriber

2 years = 3 * 250

rate = (250 / 750) * 100

rate = 30%

We can substitute the values into the formula and solve

A = 250(1 + 0.3)¹⁰

A = 3446.46

They are expected to have 3446 subscribers after 10 years

Determine the equation of the ellipse with foci (2, 4) and (2, -8), and co-vertices
(10,-2) and (-6, -2).

Answers

The equation of ellipse with foci (2, 4) and (2, -8) and co-vertices (10, -2) and (-6, -2) is ((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

What is the equation of ellipse

To find the equation of the ellipse, we first need to determine the center of the ellipse. Since the foci are on the same vertical line, the center of the ellipse is at the midpoint of the segment connecting the foci.

The midpoint of the segment connecting the foci is:

((2+2)/2, (4-8)/2) = (2, -2)

So the center of the ellipse is (2, -2).

Next, we need to determine the lengths of the semi-major and semi-minor axes. The semi-major axis is half the distance between the co-vertices, which is:

a = (10 - (-6))/2 = 8

The semi-minor axis is half the distance between the foci, which is:

c = (4 - (-8))/2 = 6

Now we can use the standard form of the equation of an ellipse centered at (h,k):

((x - h)^2 / a^2) + ((y - k)^2 / b^2) = 1

where a is the length of the semi-major axis and b is the length of the semi-minor axis.

Plugging in the values we have:

((x - 2)^2 / 8^2) + ((y + 2)^2 / 6^2) = 1

Simplifying and rearranging:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

So the equation of the ellipse is:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

Step-by-step explanation:

A graphing calculator produces a graph very nicely.

__

Setting x=0, you have the equation y=9, so you know the y-intercept.

Setting y=0, you have the equation 2x=9, so you know the x-intercept is 9/2 = 4.5. It can be easier to set y=1 to find the corresponding point x=(9-1)/2 = 4.

Through the points (0, 9) and (4, 1), you can draw the line representing the relation.

Answers

Answer:

(3,-1)

Step-by-step explanation:

So we have the system of equations:

\(3x+y=8\\2x-y=7\)

As directed, add straight down. The y-variable will cancel:

\(5x=15\)

Now, divide both sides by 5. The left cancels:

\(x=3\)

So x is 3.

Now, substitute 3 for x in either of the equations:

\(3x+y=8\)

Substitute 3 for x:

\(3(3)+y=8\)

Multiply:

\(9+y=8\)

Subtract 9 from both sides:

\(y=-1\)

So, our answer is: x=3, y=-1 or (3,-1).

The volume of the composite figure is 6,330.24 in^3

How to find the volume of the figure?

We know that the volume of half a sphere of radius R is:

V = (2/3)*pi*R^3

Here we know that pi = 3.14 and R = 12 inches, then the volume is:

V = (2/3)*3.14*(12 in)^3 = 3,617.28 in^3

And the volume of a cone of height H and radius R is:

v = (1/3)*pi*R^2*H

So here the volume is:

v = (1/3)*3.14*(12in)^2*18in = 2,712.96 in^3

The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).

First, let's find the slope of the line using the formula:

slope (m) = (change in y) / (change in x)

m = (0 - 4) / (5 - 3)

m = -4 / 2

m = -2

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Using the point (3, 4) as our reference point, we have:

y - 4 = -2(x - 3)

Expanding the equation:

y - 4 = -2x + 6

Simplifying:

y = -2x + 10

Now, let's check the given options to find the linear function with the same y-intercept:

Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)

The y-intercept is the same as the given line (10). So, this option is correct.

Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)

The y-intercept is not the same as the given line. So, this option is not correct.

Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
