The surface area of a sphere of radius 5 cm is five times the area of the curved surface of a cone of radius 4 cm. Find the height and the volume of the cone.
The height of the cone is 24.6cm and the volume of the cone is 1/3 * pi * 4^2 * 24.6 = 268.08cm^3
We can start by using the formulas for the surface area of a sphere and the curved surface area of a cone. The surface area of a sphere is given by 4 * pi * r^2, where r is the radius of the sphere. The curved surface area of a cone is given by pi * r * l, where r is the radius of the base of the cone and l is the slant height of the cone.
Given that the surface area of the sphere is five times the area of the curved surface of the cone, we can write the following equation:
4 * pi * (5^2) = 5 * pi * r * l
We can then solve for the slant height l of the cone:
l = (4*5^2) / r
Given that the radius of the cone is 4 cm, we can substitute this into the equation and solve for l:
l = 100/4 = 25cm
The volume of the cone is 1/3 * pi * r^2 * h, where r is the radius of the base and h is the height of the cone.
As we know the slant height and radius of the cone, we can use the Pythagorean theorem to find the height of the cone:
h = sqrt(l^2 - r^2) = sqrt(25^2 - 4^2) = sqrt(625 - 16) = sqrt(609) = 24.6cm
Therefore, the height of the cone is 24.6cm and the volume of the cone is 1/3 * pi * 4^2 * 24.6 = 268.08cm^3

A card is picked at random from a standard deck of cards. What is the sample space for this experiment if you were trying to find P(face card)? a. Sample space = 12 b. Sample space = c. Sample space = d. Sample space = 52
The sample space of the experiment is 52.
What is probability?The possibility that an event will occur among all potential events is known as probability. It ranges from 0 to 1. The probability is calculated by dividing the number of things by all of the items. Population includes the sample. When studying the entire population is challenging, it is studied.
52 cards in a deck
There are 12 face cards.
The experiment needs a sample space of 52 to find the face cards.
Given that a regular deck of cards is available.
The sample space required for the experiment to determine the probability of face cards must be found.
A face card may or may not be revealed when we pull a card from the deck. So, in order to rule out the possibility that a face card is present at the end of the deck, we must draw every card from a regular deck.
52 samples are therefore required for the experiment.

circle c shown below was dilated with the origin as the center of dilation to create circle C' which rule represents the transformation?
Answer:
A. (x, y) → (2/7x, 2/7y)Step-by-step explanation:
Equation of the smaller circle:
x² + y² = 2²Equation of the greater circle:
x² + y² = 7²The scale factor is the ratio of radiuses:
k = r₁ / r₂ = 2/7So the rule is:
(x, y) → (kx, ky) = (2/7x, 2/7y)Correct choice is A
Answer:
[tex]\sf A. \quad (x, y) \rightarrow \left(\dfrac{7}{2}x, \dfrac{7}{2}y \right)[/tex]
Step-by-step explanation:
The distance from the center of the circle to any point on the circumference is the radius.
From inspection of the given graph:
Radius of Circle C (before dilation) = 2 unitsRadius of Circle C' (after dilation) = 7 unitsTo find the scale factor of the dilation from the small circle C to the large circle C', divide the radius of the large circle by the radius of the small circle.
Therefore, the dilation is an enlargement of scale factor ⁷/₂ about the origin.
So the rule that represents the transformation is:
[tex]\sf (x, y) \rightarrow \left(\dfrac{7}{2}x, \dfrac{7}{2}y \right)[/tex]
Check (see attached):
Point (0, 2) is on circle C.
[tex]\implies \sf (0, 2) \rightarrow \left(\dfrac{7}{2}(0), \dfrac{7}{2}(2) \right)=(0,7)[/tex]
Point (1, √3) is on Circle C:
[tex]\implies \sf (1, \sqrt{3}) \rightarrow \left(\dfrac{7}{2}(1), \dfrac{7}{2}(\sqrt{3}) \right)=\left(3.5,6.06)[/tex]

EXPLANATION
2025 is a perfect square number hence we can determine its square root. 45 is the square root of 2025 as 45 multiplied by 45 gives the number 2025. Interestingly, – 45 × – 45 is also 2025. Hence It is represented as √2025 = 土45.
Why can the sine ratio never be greater than 1?
Because the sine and cosine ratios involve dividing a leg (one of the shorter two sides) by the hypotenuse (the longest side), the ratio values will never be greater than one, because (some number) / (a larger number) is always less than one.
What is sine and cosine?Sine & cosine are trigonometric functions of an angle in mathematics. In the context of a right triangle, the sine and cosine of an acute angle are defined as follows: for the specified angle, the sine is the ratio of the length of the side opposite that angle to the length of the triangle's longest side (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse.
The sine and cosine functions for an angle θ are simply denoted as sin θ and cos θ. In general, the definitions of sine and cosine can be extended to any real value expressed in terms of the lengths of specific line segments in a unit circle.

Some recent studies suggest that a teenager sends an average of 60 texts per day. For each of
the following scenarios, find the linear function that describes the relationship between the input
value and the output value. Then, determine whether the graph of the function is increasing,
decreasing, or constant.
a. The total number of texts a teen sends is considered a function of time in days. The input is
the number of days, and output is the total number of texts sent.
b. A teen has a limit of 500 texts per month in his or her data plan. The input is the number of
days, and output is the total number of texts remaining for the month.
c. A teen has an unlimited number of texts in his or her data plan for a cost of $50 per month.
The input is the number of days, and output is the total cost of texting each month
Type the correct answer in the box.
The number of guests per month at a large resort is given in the table below, where f(x) is the number of guests, in hundreds, x months since the beginning of the year.
Use the data in the table to create the standard form of the function that models this situation, where a, b, and c are constants.
x 0 2 4 6 8 10
f(x) 10 15 18 19 18 15
f(x)=ax^2+bx+c
Answer:
It appears that you are trying to find a quadratic function in standard form that models the number of guests at the large resort as a function of the number of months since the beginning of the year.
To do this, you can use the given data points to solve for the constants a, b, and c in the standard form of the quadratic function f(x) = ax^2 + bx + c.
To find the values of a, b, and c, you will need to have at least three data points. You can then use these data points to solve a system of three equations with three variables.
For example, using the data points (0, 10), (2, 15), and (4, 18), you can set up the following system of equations:
f(0) = 10 = a(0)^2 + b(0) + c
f(2) = 15 = a(2)^2 + b(2) + c
f(4) = 18 = a(4)^2 + b(4) + c
Solving this system of equations will give you the values of a, b, and c that you can use to write the standard form of the quadratic function that models the data.

Step-by-step explanation:
Have a nice day!
The expected value E(x) of 1 ticket is $0.40.
How to calculate the total amount?To calculate the total amount by the formula;
Amount = Ticket x Value
Raffle 1
Given;
Tickets = 800
Value = $2 per ticket
Grand ticket = $450 ...for 1
consolation =$100.. for 2
We need to find the expected value of each ticket;
First, we have to calculate the total amount of the 800 tickets
Amount = Ticket x Value
Amount = 800 x 2
Amount = 1600
Next, we have to calculate the total amount of the prizes
Amount = Ticket x Value
Amount = 450 x 200
Amount = 650
The expected value E(x) of 1 ticket is calculated:
E(x) = 650 / 1600

If £2000 was put into a bank acount that pays 3% compound intrest per year, how much will be in the account after 2 years
Answer:
After 2 years, there will be £ 2,121.80 in the account.
Step-by-step explanation:
Since £ 2000 was put into a bank account that pays 3% compound intrest per year, to determine how much will be in the account after 2 years the following calculation must be performed:
2000 x (1 + 0.03 / 1) ^ 1x2 = X
2000 x 1.03 ^ 2 = X
2,121.8 = X
Therefore, after 2 years, there will be £ 2,121.80 in the account.
In the figure shown, EF is tangent to the circle at F, and EG is
tangent to the circle at G. Line segments HF, PG, HJ, and PJ
are also tangent segments.
When mEF = 10 units, what is the perimeter of triangle EHP?
Explain your reasoning.
Answer:
The perimeter is 20 units----------------------------------
According to the two-tangent theorem, two tangent segments drawn to one circle from the same external point are congruent.
That is:
EF = EG,HF = HJ,PJ = PG.We have EF = 10 units, it means EG is also 10 units.
The perimeter of triangle EHP is:
P = EH + HP + EPWe can substitute:
HP = HJ + PJ, segment addition,HJ = HF, stated above,PJ = PG, stated above.Then the perimeter is:
P = (EH + HF) + (EP + PJ) = EF + EG = 10 + 10 = 20 unitsHow many zeros are at the end of the product $25 \times 240$?
Answer: There are three 0s
240 x 25 = 6000 and there are three 0s in 6000
