Given:

Dimensions of a block are w = 5 cm, l = 8 cm, h = 12 cm.

To find:

The length of the space diagonal of a block.

Solution:

Length of the diagonal is

Diagonal=\sqrt{l^2+w^2+h^2}

Putting the given values, we get

Diagonal=\sqrt{(8)^2+(5)^2+(12)^2}

Diagonal=\sqrt{64+25+144}

Diagonal=\sqrt{233}

Diagonal=15.2643375...

Round to the nearest tenth.

Diagonal\approx 15.3

So, the length of the space diagonal of a block is 15.3 cm.

Therefore, the correct option is B.

Answer:

y = 2x+3

Step-by-step explanation:

Sorry I'm probably too late since Quizziz doesn't wait unless you have the freeze timer thing.

y = mx+b

b is the y intercept. The y intercept (when x=0) is given in the table.

Now plug a coordinate in to solve for m.

My coordinates: (1,5)

5 = m + 3

Solve.

2 = m

m = 2

Note: never plug in the y intercept when looking for m.

You can also find the slope by (subtracting the y value of one coordinate from another y value of another coordinate)/(subtracting x value from the first y coordinate above from the x value from the second coordinate).

In this case, it'd be

m = (7-5)/(2-1)

m = 2/1

m = 2
