The total surface area of a cube is 294cm^2.

Work out the volume of the cube.​

Answers

Answer:

343 cm ^3

Step-by-step explanation:

A cube has 6 squares of equal sizes. 294/6 = 49

The area of one square is 49

Since the area is the length squared, the square root of 49 is 7.

Volume of a cube is area times height. 49 x 7 = 343 cm^3

Answer:

[tex]\frac{6}{5}[/tex] or [tex]1\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]\frac{2}{5} *3[/tex]

3 can be rewritten as 3/1

[tex]=\frac{2}{5}*\frac{3}{1}[/tex]

Multiply the numerators and denominators

[tex]2*3=6\\5*1=5[/tex]

[tex]= \frac{6}{5}[/tex]

You can also change this into a mixed number by dividing the numerator by the denominator and writing the remainder as the numerator:

[tex]= 1\frac{1}{5}[/tex]

Which quadratic function in vertex form has a vertex at (−5 , −4) and passes through the point (−2 , −1)?

y=−13(x+5)^2−4

y=−13(x−5)^2+4

y=13(x−5)^2−4

y=13(x+5)^2−4

Answers

Answer:

y = 1/3(x + 5)^2 - 4

Step-by-step explanation:

The general vertex form is;

y = a(x-h)^2 + k

From the question, (h,k) are the coordinates of the vertex which is (-5,-4)

So we have

y = a(x + 5)^2 -4

So we need to get the leading coefficient

Simply substitute the point it passes through

x = -2 and y = -1

-1 = a(-2 + 5)^2 - 4

-1 = a(3)^2 -4

-1 = 9a -4

9a = 4-1

9a = 3

a = 3/9

a = 1/3

So the equation is;

y = 1/3(x + 5)^2 - 4

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?

Answers

Answer:

17 units

Step-by-step explanation:

Moving from (-8, 0) to (7, 8), we see x changing by 15 units from -8 to 7 and y changing by 8 units from 0 to 8.

Regard 15 units as the horizontal leg of a right triangle and 8 units as the vertical leg.  We use the Pythagorean Theorem to determine the length of the hypotenuse of this right triangle and interpret the result as the distance between the points:

d = √(15² + 8²) = √289 = 17

The distance between the given points is 17 units.
