math plz help due day its so close

Answer:

28π

Step-by-step explanation:

surface area of a cylinder formula:

2πr²+2πrh

plugging in what we know

2π2²+2π2*5

8π+20π= 28π

Answer:

28π cm2

Step-by-step explanation:

they wrote the answers wrong the answers A

got it right on the test

"28π cm2"

Answer:

768[tex]m^{3}[/tex]

Step-by-step explanation:

Pyramid volume will be base · height over 3

pyramid volume = 64 · 6 / 3

Pyramid volume = 128

--------------------------------------------------------------------------------------------------------------

Prism volume will be base · height

prism volume = 64 · 10

prism volume = 640

--------------------------------------------------------------------------------------------------------------

Now add the sum of the two volumes

640 + 128 = 768[tex]m^{3}[/tex]

--------------------------------------------------------------------------------------------------------------

Answer:

slope = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 4 ) ← 2 points on the line

m = [tex]\frac{4-0}{1-0}[/tex] = [tex]\frac{4}{1}[/tex] = 4

Answer:

(-4, 3)

x = -4, y = 3

Answer:

A. (x+8)(x+8)

Step-by-step explanation:

F: x*x=x^2

O: x*8=8x

I: 8*x=8x

L: 8*8=64

x^2+8x+8x+64 = x^2+16x+64

I know its right

Answer:Jonathan is incorrect.

Step-by-step explanation:A quadrilateral has 4 straight sides is a four sided shape which means 4 straight sides.The image you have showed me does not have 4 straight sides nor 4 edges nor 4 verticals.So Jonathan is incorrect.

Hi there!

I believe your answer is:  

1.5 square meters

»»————-　★　————-««  

Here’s why:  

As given in the question you have asked, the surface area of a cube can be found with:

[tex]SA=6s^2\\\\SA - \text{Surface Area}\\\\S- \text{A given side length.}[/tex]

⸻⸻⸻⸻⸻

We are given the side length of 0.5 meters. This means that we have to substitute the variable 's' for '0.5' to find the surface area.

⸻⸻⸻⸻⸻

[tex]\boxed{\text{Surface Area of a cube with a side length of 0.5 meters:}}\\\\------\\\\SA= 6(0.5)^2\\\\\rightarrow SA=6(0.25)\\\\\rightarrow \boxed{SA=1.5}\\\\------[/tex]

⸻⸻⸻⸻⸻

[tex]\text{The surface area of the cube should be }\boxed{\text{1.5m}^2\text{.}}[/tex]

Hope this helps you. I apologize if it’s incorrect.

Step-by-step explanation:

Answer: Y is equal to 1

Step-by-step explanation:

If any variable is by itself like for example 1 + y, that variable would equal one because it's all by itself so it attomatically equals 1. But if the variable was with another number like 1y, then it would mean you have to multiply it by whatever why would equal.

[tex](x + 5)(x + 2)[/tex]

Use the algebraic identity,

[tex](x + a)(x + b) \\ = {x}^{2} + (a + b)x + ab[/tex]

Now,

a = 5

b = 2

Substitute the values of a & b in the identity & solve the equation.

[tex] {x}^{2} +( a + b)x + ab \\ = x {}^{2} + (5 + 2)x + 5 \times 2 \\ = {x}^{2} + 7x + 10[/tex]

[tex]✎ \: (x + 5)(x + 2) = {x}^{2} + 7x + 10[/tex]

Step-by-step explanation:

Divide each term by 3 and simplify. x = 2

Answer: CAN U MARK BRAINLIST!!!!! You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Given two points (x1, y1) and (x2, y2), the formula for the slope of the straight line going through these two points is:

\small{ m = \dfrac{y_1 - y_2}{x_1 - x_2} }m=

...where the subscripts merely indicate that we have a "first" point (whose coordinates are subscripted with a "1") and a "second" point (whose coordinates are subscripted with a "2"); that is, the subscripts indicate nothing more than the fact that we have two points that we're working with. Note that which point we pick as the "first" point is irrelevant; if we pick the other point to be "first", the subtractions will be reversed, but we'll still get the exact same value for the slope:

Answer:

Yes

Step-by-step explanation:

In any triangle, the sum of any two sides must be larger than the third side. To test this, we only actually need to pick the two shorter sides. In this case, the following inequality is true:
