The surface area of a cylinder with height 2 in. is given by the function f(x) = 2πx2 + 4πx, where x is the radius. If g(x) = 4πx gives the surface area of the side of the cylinder, which combined function gives the total surface area of the two circular bases?

A. f + g
B. g − f
C. f − g
D. f · g

Answers

Answer 1

Answer:

C f - g

Step-by-step explanation:

the surface area of a cylinder consists of the two circles (1 at the top, 1 at the bottom) and the surrounding "mantle", the side of the cylinder, that connects the two circles.

there are no other parts.

so, when the function for the whole surface area is

SA(x) = f(x) = 2×pi×x² + 4×pi×x

and the side/ mantle area by itself is

g(x) = 4×pi×x

then when ignoring the side/mantle area part in f(x) the only thing left of the main function f(x) is the surface area of the two circular bases.

therefore, the solution for the function of the surface area of only the two circular bases must be the main function minus the function for the side/mantle area.

=> f - g

Using the Exxon data as an example pretend Pennys Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares what percent of Penny's Picklesdo you own

Answers

you would own 2% of penny’s Picklesdo i hope this helps

Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.

What is percentage?

Percentage a is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]\%[/tex].

Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]

We have,

Total shares of Penny's Pickles [tex]=10,000[/tex]

You owned shares [tex]= 200[/tex]

So,

Using above formula,

Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]

Percentage of shares I owned [tex]=\frac{200}{10000} * 100[/tex]

[tex]= 2 \%[/tex]

So, the shares you owned are [tex]2\ \%[/tex] of total share of the Penny's Pickles.

Hence, we can say that Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.

x² = 253 ( take the square root of both sides )

x = [tex]\sqrt{253}[/tex] ≈ 15.9 ( to the nearest tenth )

A cake weighs 215 g and is shared equally between five people. What weight of cake does each person receive?

Answers

Answer: 43 g

Step-by-step explanation: For 215 to be divided equally between five people the equation should be set up as 215/5, which equals 43 g for each person.

You just have to divide the weigh of the cake by the number of people that’ll be sharing it

For example 215g dived by 5 is 43g
Therefore each person receive 43g of the cake.

The correct option is (B)

Step-by-step explanation: We are given to match the graph with its correct equation.

From the graph, we note that

there is a straight line where the points (7, 0) and (0, -7) lie on it.

So, the slope of the line is given by

Since the line passes through the point (7, 0), so its equation will be

Thus, the required equation of the graphed line is
