PLZ HELP! What Is The Total Surface Area Of This Rectangular Prism In Square Centimeters? Choices Are:A:

Answers

Answer 1
The answer is 675cm squared (C)
Answer 2

Answer:

Step-by-step explanation:

Surface area of a rectangular prism is

A=2(xy+xz+yz) where x,y,z are its dimensions so

A=2(15(10)+15(7.5)+10(7.5)

A=2(150+112.5+75)

A=2(337.5)

A=675cm^2

Answer:

parabola y = -6x=2 and x=6Greatest value of y is y=2 and it occurs when x = 4For x between x = 2 and x = 6, y > 0

Step-by-step explanation:

Definition

A parabola is a curve where any point is at an equal distance from:

               a fixed point (the focus ), and

               a fixed straight line (the directrix )

From the graph we can see that this is indeed so. We can even calculate the parabola equation from the given graph but since that is not required, I am not illustrating the steps here to do that

The y-intercept is the value of y where the parabola cuts the y axis and from the graph we see that this occurs at y = -6The x-intercepts are the x-values where the parabola crosses the x-axis and we can see that this occurs at x = 2 and x = 6The greatest value of y occurs at the vertex of the parabola and we see that the vertex is at (4,2) ie greatest value of y is at y = 2 and occurs at x=4Between x =2 and x = 6 we see that the y values greater than 0 ie y > 0

(Note on last question: If you exclude these two points then y > 0 between x=2 and x=6.Specifically it is 0 at x =2 and x=6 and > 0. So if you include these two points then y ≥ 0.  I have taken it as excluding the two points, x = 2 and x =6)

Answer: parabola y=-6 x=2 and x=6 Greatest value of y is y=2 and it occurs when x = 4 For x between x = 2 and x = 6, y >0 Step-by-step explanation: Definition A parabola is a curve where any point is at an equal distance from: a fixed point (the focus), and a fixed straight line (the directrix ) From the graph we can see that this is indeed so.

Answers

The Falcons had the best overall record for the season. They have a larger mean value of about 20.9 points. The mean is the best measure of center to compare in this case because it takes into account all the data points and gives an overall average of the points earned by each team throughout the season.

How can I find the cube root of 64?

Answers

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.
