The answer to the two questions about total surface area and lateral surface area are; Tripling the radius will increase the total surface area and the lateral surface area is 464.7 cm²

The formula for the total surface area of a right circular cone is;

T.S.A = πrl + πr²

4) Cone has the following dimensions;

Radius; r = 2.9 m

Slant Height; l = 13.8 m

Thus, if we triple the radius, we have;

T.S.A = π(3 * 2.9 * 13.8) + π(3 * 2.9)²

T.S.A = 195.75π

But if we triple the slant height, we have;

A = π(2.9 * 3 * 13.8) + π(2.9)²

A = 128.47π

Thus, tripling the radius will increase the surface area

B) Formula for lateral surface area of a cone is;

L.S.A = πrl

L.S.A = π * 14.8 * 10

L.S.A ≈ 464.7 cm²

Answer:

GCF: y³z³

Step-by-step explanation:

The greatest common factor is the a term that you can take out of all the terms given to you. This term, when multiplied to each of the individual numbers in the set, will return you to the original amount.

In this case, note that they all share the variables y and z, and that each of them have at least 3 y's and 3 z's. For you to factor, you will divide these from all the terms.

[tex]\frac{x^{3}y^{5}z^{5} , y^{3}z^{5} , xy^{3}z^{3} }{y^{3}z^{3}} = x^{3}y^{2}z^{2} , z^{2} , x[/tex]

Answer:

[tex]y=8[/tex]

Step-by-step explanation:

[tex]\frac{2}{7} =\frac{y}{28}[/tex]

Multiply both sides by 28.

[tex]\frac{2}{7} * 28=y[/tex]

Express [tex]\frac{2}{7} *28[/tex] as a single fraction.

[tex]\frac{2*28}{7} =y[/tex]

Multiply 2 and 28 to get 56.

[tex]\frac{56}{7}=y[/tex]

Divide 56 by 7 to get 8.

[tex]8=y[/tex]

Swap sides so that all variable terms are on the left hand side.

[tex]y=8[/tex]

Answer:

Step-by-step explanation:

Given function:

Find s( - 6):

Let S be the sum of the first n terms of the left side:

[tex]S = \dfrac23 + \left(\dfrac23\right)^2 + \left(\dfrac23\right)^3 + \cdots + \left(\dfrac23\right)^n[/tex]

Multiply both sides by 2/3 :

[tex]\dfrac23 S = \left(\dfrac23\right)^2 + \left(\dfrac23\right)^3 + \left(\dfrac23\right)^4 + \cdots + \left(\dfrac23\right)^{n+1}[/tex]

Subtract this from S :

[tex]S - \dfrac23 S = \dfrac23 - \left(\dfrac23\right)^{n+1}[/tex]

Solve for S :

[tex]\dfrac13 S = \dfrac23 - \left(\dfrac23\right)^{n+1}[/tex]

[tex]S = 2 - 3 \left(\dfrac23\right)^{n+1}[/tex]

As n gets larger and larger, S converges to the given sum, and the term (2/3)ⁿ⁺¹ converges to zero, which leaves us with

[tex]\displaystyle \lim_{n\to\infty} S = \boxed{x = 2}[/tex]

The area of the wall is 72 ft square.

A rectangle is a 2-dimensional quadrilateral with four right angles which sum up to 360 degrees.

Area of a rectangle = length x width

The area of one wall = height of the room x width of the floor.

Width of the floor = √144 = 12 ft

Area = 12 x 6 = 72

The given expression is less than 1.

Buster was given this expression and asked to determine whether the answer is greater than or less than 1. (9.763 × 10^8) (1.56 × 10^13).

If the numerator is less than the denominator the fraction is called proper fraction and it is greater than 0 but less than 1.

The given expression is;

[tex]\dfrac{9.763 \times 10^8}{1.56 \times 10^{13}}[/tex]

The given function is numerator [tex](9.763 \times 10^8)[/tex] is less than [tex](1.56 \times 10^{13})[/tex] the denominator.

Therefore,

[tex]10^8<10^{13}[/tex]

Answer:

See below.

Step-by-step explanation:

Part A

"The graph passes through (0,2), (2,6), (3,12).

If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points.

Using (0,2) and (2,6), the slope would be 2.

Using (2,6) and (3,12), the slope would be 3 1/3.

Since the slope is not constant everywhere, the function is non-linear."

Part B

An example of a linear function is y=2x+6.

An example of a nonlinear function is xy=3.

Answer:

the correct information is 15

Answer:

To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.

(f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f  × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(

The zero in the power of any number is equal to the 1.

To write the big number in short form, we write them in the power of 10. The zero in the power of any number is equal to the 1.

Given information-

The given number whose product has to find out are 4.17 and [tex]2.3\times10^6[/tex].

Let [tex]x[/tex] be the product of the given number. thus,

[tex]x=4.17\times(2.3\times10^6)[/tex]

As the zero in the power of any number is equal to the 1.  Thus the number 4.17 can be written as [tex]4.17\times10^0[/tex].

Write the first number in the form of exponent of 10. as,

[tex]x=4.17\times10^0\times(2.3\times10^6)[/tex]

Hence the option A is correct and B is incorrect.

Rearrange it by numbers,

[tex]x=(4.17\times2.3)\times10^6[/tex]

Multiply number 4.17 and 2.3 in the calculator we get,

[tex]x=9.591\times10^6[/tex]

Lets check other options,

Hence,

The zero in the power of any number is equal to the 1.

1 / 7 is equal to 1 / 7

Hey there!

3:21
