What is the transformation of C(9, 3) when dilated by a scale factor of 3, using the origin as the center of dilation?
The transformation of C(9, 3) when dilated by a scale factor of 3, using the origin as the center of dilation is:
C'(27,9)
Step-by-step explanation:Dilation transformation--
A dilation transformation is a transformation which changes the size of the original figure but the shape remain unchanged.
i.e. if any figure is dilated by a scale factor k with the center of dilation as origin.
Then the change pr transformation in each of the vertices of the figure is given by:
(x,y) → (kx,ky)
We are given a point C which is located at C(9,3)
Hence, here k=3
Hence, we get:
C(9,3) → C'(9×3,3×3)
i.e. C(9,3) → C'(27,9)

Final answer:
To determine the height of a tree that casts a 10 ft shadow, using the ratio from a 6 ft tree that casts a 3.25 ft shadow, we find the tree is approximately 18.46 feet tall through the concept of similar triangles.
Explanation:
The question asks how tall a tree is that casts a 10 ft shadow, given that a 6 ft tree casts a 3.25 ft shadow. This problem can be solved using the concept of similar triangles, where the ratio of the heights of the trees is equal to the ratio of the lengths of their shadows.
To find the height of the tree that casts a 10 ft shadow, we set up the proportion as follows:
Height of first tree / Shadow of first tree = Height of unknown tree / Shadow of unknown tree
Substituting the given values:
6 ft / 3.25 ft = Height of unknown tree / 10 ft
By cross-multiplying and solving for the height of the unknown tree, we get:
(6 ft × 10 ft) / 3.25 ft = 18.46 ft
Therefore, a tree that casts a 10 ft shadow is approximately 18.46 feet tall.
A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity in a manner that can be described by the linear function −4x + 3y = 21, where x is time and y is velocity in kilometers per hour. Use this function to determine when a certain particle will reach 40km/hr.
The particle will reach 40km/hr when X=_____
Final answer:
To determine when the particle will reach a velocity of 40km/hr, substitute the value of y into the linear function and solve for x. The particle will reach 40km/hr when x = 24.75.
Explanation:
To determine when a certain particle will reach a velocity of 40km/hr, we need to find the value of x in the given linear function −4x + 3y = 21. Since y represents velocity, we can substitute 40 for y and solve for x.
By substituting 40 for y, we get −4x + 3(40) = 21. Simplifying the equation, we have −4x + 120 = 21. Rearranging the equation, we get −4x = 21 - 120 = -99.
Dividing both sides of the equation by -4, we find that x = 99 / 4 = 24.75.
Therefore, the particle will reach 40km/hr when x = 24.75.
To determine when the particle will reach 40 km/hr, substitute the value into the equation and solve for x. The particle will reach 40 km/hr when x = 24.75.
Explanation:The linear function −4x + 3y = 21 describes the relationship between time (x) and velocity (y) of light particles in a particle accelerator. To determine when a certain particle will reach 40 km/hr, we can substitute the value of y as 40 into the equation and solve for x.
−4x + 3(40) = 21
Simplifying the equation, we get -4x + 120 = 21
Combining like terms, -4x = 21 - 120 = -99
Dividing both sides by -4, we find that x = -99/(-4) = 24.75
Therefore, the particle will reach 40 km/hr when x = 24.75.

Find the greatest possible enclosed area of a rectangular corral given 400 feet of fencing
Answer:
Maximum area = 10000 square units.
Step-by-step explanation:
We are given the following information:
Rectangular perimeter of coral = 400 units.
Let length of the coral be x. Then,
Perimeter = 400 = 2(Length +Breadth)
[tex]400 = 2(x + Breadth)\\Breadth = 200 - x[/tex]
Thus, the area of rectangle is given by,
[tex]Area = Length\times Breadth = x\times (200-x) = 200x - x^2[/tex]
Thus, we have to maximize the function:
[tex]f(x) = 200x - x^2[/tex]
We will use double derivative test.
First we differentiate with respect to x.
[tex]\displaystyle\frac{d(f(x))}{dx} = \displaystyle\frac{d(200x - x^2)}{dx} = 200 - 2x[/tex]
Equating this to zero to obtain critical points,
[tex]200 - 2x = 0\\200 = 2x\\x = 100[/tex]
Now, again differentiating with respect to x.
[tex]\displaystyle\frac{d^2(f(x))}{dx^2} = -2 < 0[/tex]
Thus, by double derivative test, local maxima occurs for this function at x = 100
So, Length = x = 100 units
Breadth = 200 - x = 100 units
Maximum area = 10000 square units.

A cylindrical chemical storage tank mush have a height 4 meters greater than the radius of the top of the tank. determine the radius of the top and the height of the tank if the tank must have a volume of 15.71 cubic meters
Final answer:
To determine the radius and height of the cylindrical tank with a given volume of 15.71 cubic meters, where height is 4 meters greater than the radius, we use the volume formula for a cylinder, resulting in a cubic equation that must be solved.
Explanation:
The question asks for the radius of the top and the height of a cylindrical tank with a volume of 15.71 cubic meters, where the height is 4 meters greater than the radius. The formula for the volume of a cylinder is V = πr²h, where V is volume, r is radius, and h is height. Since h = r + 4, we can write the equation in terms of r as V = πr²(r + 4).
To find the radius, we substitute the given volume, 15.71 m³, into the equation:
15.71 = πr²(r + 4)
This results in a cubic equation which we need to solve to find the value of r. After solving (which may require numerical methods or approximations due to the complexity of cubic equations), we find the value of the radius and can then determine the height by adding 4 meters to the radius.
Write the inverse function for the function,f(x)=1/2x+4then, find the value of ƒ-^1(4) type your answers in the box
The inverse function of the above function is f(x) = 2x - 8 and therefore the function at 4 would be equal to 0.
You can find the inverse of any function by switching the f(x) and x terms. Once you have done that, solve for the new f(x). Finally, what you'll have remaining is the inverse function. The work is done for you below:
f(x) = 1/2x + 4 ----> Switch the x and f(x)
x = 1/2f(x) + 4 ---> subtract 4 from both sides
x - 4 = 1/2f(x) ----> multiply both sides by 2
f(x) = 2x - 8
This would be your inverse function. Now to find f-1(4) you would put 4 in for x in your new inverse function.
f(x) = 2x - 8
f(4) = 2(4) - 8
f(4) = 8 - 8
f(4) = 0
A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second. 1 m = 10 dm 1000 m = 1 km How much faster does the sea turtle swim than the girl in meters per minute?
Final answer:
Calculate how much faster a sea turtle swims than a girl in meters per minute by converting their speeds to a common unit and finding the difference.
Explanation:
To find out how much faster the sea turtle swims than the girl in meters per minute, we need to convert their speeds to a common unit. Let's first convert the girl's speed to kilometers per hour:
Girl's speed = 14 decimeters per second = 1.4 meters per second = 5.04 kilometers per hour
Now, we compare the speeds:
Sea turtle speed = 27 kilometers per hour
Girl's speed = 5.04 kilometers per hour
Sea turtle swims 21.96 kilometers per hour faster than the girl. To find how much faster this is in meters per minute:
21.96 km/h * 1000 m/km / 60 min/h = 366 meters per minute
