The total surface area is π[(4/3)x]² + π(4/3)x². The base area is greater than the lateral area.
What is an equation?An equation is an expression that shows how numbers and variables are related using mathematical operations. Equations can be linear, quadratic, cubic and so on.
Given the cone. The surface area (SA) is given by the equation:
SA = πr² + πrs
where r is the radius of the cone and s is the slant height.
Given that the slant height is x and the radius of the cone is 4/3 the slant height = (4/3)x
Hence:
SA = πr² + πrs
substituting:
SA = π[(4/3)x]² + π(4/3)x(x)
SA = π[(4/3)x]² + π(4/3)x²
The base area = π[(4/3)x]², the lateral area = π(4/3)x²
The base area is greater than the lateral area.

Point W is located at (-5, -3). Select all of the following that are 5 units away from point W
These are the four points that are exactly 5 units away from point W. To find points that are 5 units from point W, which is located at (-5, -3).
To find points that are 5 units from point W, which is located at (-5, -3), we need to find all points that are a distance of 5 units away from (-5, -3) using the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the distance between two points) is equal to the sum of the squares of the lengths of the other two sides
Given a point (x, y), the distance between that point and point W can be found using the formula:
distance = sqrt((x + 5)^2 + (y + 3)^2)
Setting this distance equal to 5 and solving for x and y, we get the following points:
(0, -8), (-10, -8), (0, 2), and (-10, 2).
These are the four points that are exactly 5 units away from point W.

Keiko was working with a new function, g(x). He wrote down the following steps for g(x):
• Add 5.
• Divide by 2.
• Cube it. (Find the third power.)
Multiply by 6.
a. What is the equation for g(x)? What is the output when 3 is put in?
b. Help Keiko write down the steps (in words) of the inverse machine, g¹(a), and then write its equation.
c. Verify that your equation in part (b) correctly "undoes" the output of g(x) in part (a).
a.) The equation for g(x) is g(x) = 6((x+5)/2)³and output is 384.
b.) The inverse machine, g¹(a), we need to undo each of the four steps in reverse order is g¹(a) = [tex]((a/6)^{(1/3)})*[/tex]2 - 5
c.) To verify that g¹(a) correctly "undoes" the output of g(x), we can plug in the output of g(3) (384) into g¹(a) and see if we get 3 as the result is 3.
What is Function?
A function is a mathematical rule that takes one or more inputs (also called independent variables or arguments) and produces a single output (also called a dependent variable or function value). In other words, a function is a relationship between the inputs and the output, where each input produces a unique output.
Functions can take many different forms and can be used to describe a wide variety of mathematical and real-world phenomena.
a. The equation for g(x) is:
g(x) = 6((x+5)/2)³
When 3 is put in for x, the output is:
g(3) = 6((3+5)/2)³= 6(4)³ = 384
b. To find the inverse machine, g¹(a), we need to undo each of the four steps in reverse order:
Undo step 4: Divide a by 6.Undo step 3: Take the cube root of the result from step 1.Undo step 2: Multiply the result from step 2 by 2.Undo step 1: Subtract 5 from the result from step 3.Putting this in equation form, we get:
g¹(a) = [tex]((a/6)^{(1/3)})[/tex]*2 - 5
c. To verify that g¹(a) correctly "undoes" the output of g(x), we can plug in the output of g(3) (384) into g¹(a) and see if we get 3 as the result:
g¹(384) =[tex]((384/6)^{(1/3)})[/tex]*2 - 5 =[tex](64^{(1/3)})[/tex]2 - 5 = 42 - 5 = 3
Since the output of g¹(a) is 3 when we input the output of g(x), we can conclude that g¹(a) correctly undoes the output of g(x).

2) Jane wants to buy some compost. Both Suttons Shop and Greens Garden Shop sell compost. Suttons Shop Bags of compost 20 litres £2.25 each bag £3.25 for 2 bags Jane needs 140 litres of compost. She wants to buy all the compost from the same shop. She wants to buy the compost as cheaply as possible. Which shop should Jane buy the compost from? You must show all your working. Greens Garden Shop Bags of compost 70 litres £4.99 each bag
The cheapest option for Jane is to buy from Suttons Shop, as the total cost is £12, whereas, at Greens Garden Shop, the total cost is £9.98.
To determine the cheapest option, we need to calculate the cost of purchasing 140 liters of compost from each shop.
First, we'll calculate the cost at Suttons Shop:
Jane needs 140 liters of compost, so she needs 140 / 20 = 7 bags of compost.
If she buys 1 bag of compost, it will cost her £2.25.
If she buys 2 bags of compost, it will cost her £3.25.
Since she needs 7 bags of compost, she can buy 3 sets of 2 bags (6 bags) and 1 bag.
So the cost of 6 bags will be 3.25 x 3 = £9.75, and the cost of 1 bag will be 2.25.
The total cost of 7 bags at Suttons Shop will be 9.75 + 2.25 = £12.
Next, we'll calculate the cost at Greens Garden Shop:
Jane needs 140 liters of compost, so she needs 140 / 70 = 2 bags of compost.
Each bag at Greens Garden Shop costs £4.99.
So the total cost of 2 bags at Greens Garden Shop will be 4.99 x 2 = £9.98.

Solve the equation -5(y +0.2) = 25.
y =
Answer:
y = -5 [tex]\frac{1}{5}[/tex] o r -5.02 as a decimal
Step-by-step explanation:
-5(y + 0.2) = 25 Distribute the -5
-5(y) + -5(0.2) = 25 Adding a negative is the same as subtracting a positive
-5y - 1 = 25 add 1 to both sides
-5y - 1 + 1 = 25 + 1
-5y = 26 Divide both sides by -5
[tex]\frac{-5y}{-5}[/tex] = [tex]\frac{26}{-5}[/tex]
y = -5 [tex]\frac{1}{5}[/tex] o r -5.02 as a decimal
Answer: To solve the equation -5(y + 0.2) = 25, we need to isolate y by performing the following steps:
Distribute the -5 to the expression inside the parenthesis:
-5 * y - 5 * 0.2 = 25
-5y - 1 = 25
Add 1 to both sides of the equation to isolate -5y on one side:
-5y - 1 + 1 = 25 + 1
-5y = 26
Divide both sides of the equation by -5 to find y:
(-5y) / -5 = 26 / -5
y = -5.2
So, the solution to the equation -5(y + 0.2) = 25 is y = -5.2.

A bouncy ball is dropped such that the height of its first bounce is 5 feet and each
successive bounce is 68% of the previous bounce's height. What would be the height
of the 9th bounce of the ball? Round to the nearest tenth (if necessary).
I know, I answer quick. What do you expect I'm Johnny Sins to help you with your homework. :)
Anyways,
The height of the nth bounce can be calculated using the formula:
h_n = h_1 * 0.68^(n-1)
Where h_1 is the height of the first bounce, h_n is the height of the nth bounce, and 0.68 is the percentage of the height lost with each successive bounce.
Substituting the given values, we have:
h_9 = 5 * 0.68^(9-1)
h_9 = 5 * 0.68^8
h_9 = 5 * 0.265
h_9 = 1.325
So the height of the 9th bounce would be approximately 1.3 feet, rounded to the nearest tenth.

In a class & 60 students the most number of students who passed Ga is 6 more than the number that passed fante. Every student passed at least one of the two subjects and 8 students passed both subjects (1) How many students passed Ga?
Answer: 37
Step-by-step explanation:
let x be the number of students who pass "fante". Then the number of students who passed "Ga" will be x + 6.
with the added information that 8 students passed both we can say:
(x + x + 6) - 8 = 60
2x + 6 = 68
2x = 62
x = 31
.: x + 6 = "only Ga pass" = 37
The question does not make it clear if it is asking for students who *only* passed Ga, or students who passed Ga + those who passed both. I'll assume the former though. Otherwise the answer would be 37 + 8 = 45 students

No, f(x, y) = 3x - 3y^2 is not a harmonic function.
A harmonic function is a twice continuously differentiable function f(x, y) that satisfies the Laplace equation:
∂²f/∂x² + ∂²f/∂y² = 0.
Let's check if f(x, y) = 3x - 3y^2 satisfies the Laplace equation:
∂²f/∂x² = ∂/∂x(3) = 0
∂²f/∂y² = ∂/∂y(-6y) = -6
∂²f/∂x² + ∂²f/∂y² = 0 + (-6) = -6 ≠ 0
Since the Laplace equation is not satisfied, f(x, y) = 3x - 3y^2 is not a harmonic function.
As for finding a corresponding analytic function, an analytic function is a function that is locally given by a convergent power series. Since f(x, y) is not a harmonic function, there is no corresponding analytic function.

A water well is composed of 28 cements rings with 1.4 m of diameter and 0.2 m height if labour of cost for digging out the well is RS.500 per cubic meter and cost of cement ring is 2500
The total cost of the cement rings for the water well is RS. 70,000. This cost is only for the cement rings and does not include the cost of labour for digging the well.
What is the total cost of the cement rings for the water well?The cost of each cement ring is given as RS. 2500. Since there are 28 cement rings used in the water well, the total cost of the cement rings can be calculated as follows:
Total cost of cement rings = Cost of each cement ring x Number of cement rings used
Total cost of cement rings = 28 x 2500 = RS. 70,000
Volume of the well = [tex]\mathrm{ \pi r^2h = \pi (0.7)^2(5.6) = 9.768m^3 }[/tex]
Cost of digging out the well = 500 x 9.798 = RS. 4,899
Total cost of the well = RS. 74,899
Total cost of cement rings = 2500 x 28 = RS. 70,000
Therefore, the total cost of the cement rings for the water well is RS. 70,000. This cost is only for the cement rings and does not include the cost of labour for digging the well.
