Answer:

[tex]112\pi[/tex]

Step-by-step explanation:

hi! for this problem, all we need is the equation for the SA for a cylinder!

here's the equation: [tex]A=2\pi(r)(h)+2(\pi)r^{2}[/tex]

BUT FIRST let's identify our given numbers

now all we have to do is plug in what is given to the equation above! not so bad, right?

plugged in equation

[tex]A = 2\pi (4)(10) + 2\pi (4)^{2}[/tex]

- now let's simplify!

[tex]2\pi (40) + 2\pi (16)[/tex]

[tex]80\pi + 32\pi[/tex]

[tex]112\pi[/tex]

your answer should be [tex]112\pi[/tex]

Step-by-step explanation:

y2 - y1 / x2 - x1

7 - 1 / 6 - (-2)

6 / 8

= 3/4

y = 3/4x + b

9 = 3/4(-6) + b

9 = -9/2 + b

18 blocks would fit in the Crate.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Given:

Volume of Crate= 2160 cubic inch

Now, Volume of each wooden board

= l b h

= 12 x 5 x 2

= 120

so, number of blocks = 2160/ 120

                                    = 18

Hence, 18 blocks would fit in the Crate.

Luke can fit 18 wooden boards, each measuring 12 inches in length, 5 inches in width, and 2 inches in height, into the crate with dimensions 12 inches in length, 10 inches in width, and 18 inches in height.

Given that the crate has a volume of 2160 cubic inches and the dimensions are 12 inches in length, 18 inches in height, and an unspecified width.

Each wooden board has dimensions of 12 inches in length, 5 inches in width, and 2 inches in height, we can calculate how many wooden boards Luke can fit into the crate.

Let's denote the width of the crate as "w".

The volume of the crate is given by the formula: Volume = Length × Width × Height

So, 2160 = 12 × w × 18

Solving for "w":

w = 2160 / (12 × 18)

w = 10

Now that we know the width of the crate is 10 inches, we can calculate how many wooden boards can fit in the crate by comparing their dimensions.

Each wooden board has a volume of 12 × 5 × 2 = 120 cubic inches.

The total number of wooden boards that can fit in the crate:

Number of boards = Crate Volume / Board Volume

Number of boards = 2160 / 120

Number of boards = 18

Therefore, 8 blocks would fit in the Crate.

I checked with desmos graphing calculator and the line produced is a parabola. I believe the y^2 made it into a parabola

No,  5x+y^2=25 is not a linear equation.

For the given equation;

5x+y^2=25

the highest power of the equation is 2.

Thus, the given equation is a quadratic equation or 2 degree equation.

since every f has the same value

6=6

Answer:

3f

Step-by-step explanation:

There are three f's added together, which makes 3f. If you had multiplied them all it would've been f^3, if you had divided f by 3 you would have f/3, and if f=1 it would've just been 3. This is why 3f is the best answer here.

Answer:

The expression p−0.45p can be simplified to  0.55 p.

This means Phyllis can find the new price of a hat by finding  55 % of the original price.

Step-by-step explanation:

The given expression describes that the price of the Hat would be 55% of the original price.

Given that,
Hats are on sale for 45% off. Phyllis uses the expression p−0.45p to find the new price of a hat that originally cost p dollars.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Given expression,
= p−0.45p
Simplify further,
= 0.55p
The above expression implies that the outcome is 55% of p, where p is the original price of the Hats.

Thus, the given expression describes that the price of the Hat would be 55% of the original price.

Answer:

[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} - 3 && \text{for $n \ge 1$}\end{aligned}\right.[/tex].

Step-by-step explanation:

An arithmetic sequence could be defined using only two pieces of information:

The arithmetic sequence in this question is given in the explicit form, [tex]a_{n} = 7 - 3\, (n - 1)[/tex], which is equivalent to [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]. In the explicit form, [tex]a_{1}[/tex] and [tex]d[/tex] are described in the same equation:

[tex]\text{$a_{n} = a_{1} + d\, (n - 1)$ for $n \ge 1$}[/tex].

Compare [tex]a_{n} = a_{1} + d\, (n - 1)[/tex] with [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]: [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex].

When an arithmetic sequence is given in the recursive form, [tex]a_{1}[/tex] and [tex]d[/tex] are specified in two separate equations:

[tex]\left\lbrace\begin{aligned}& a_{1} = a_{1} \\ & a_{n+1} = a_{n} + d && \text{for $n \ge 1$}\end{aligned}\right.[/tex].

In this question, it was found that [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex]. Hence, the corresponding recursive formula for this arithmetic sequence would be:

[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} + (-3) && \text{for $n \ge 1$}\end{aligned}\right.[/tex].
