Answer:

2.83 inches longer

Step-by-step explanation:

The SA of a cube is 6s^2.

Therefore the length of the side of the 1200 square inches cube is approximately 14.142 inches long.

The length of the side of the 768 square inches cube is approximately 11.314 inches long.

If you subtract those two numbers, you get the difference in the lengths which is approximately 2.83 inches.

Use finite differences to identify the degree of the polynomial that best describes the data. 9 10 11 12 13 14
worty [1.4K]

The forward differences for this data is 1, 1, 1, 1, 1, 1 (since 10 - 9 = 1, 11 - 10 = 1, etc). Since we only need one iteration of differences, a linear polynomial will fit the data exactly.

Which of the following is the correct solution to the linear inequality shown below?
Georgia [21]
Correct answer is C.

Line y=\frac{1}{3}x-2 intersects y-axis at -2 and passes through the point (3,-1).

Line must be dashed, because the inequality sign is ">".

Point (0,0) must lie in the solution set because it satisfies inequality y>\frac{1}{3}x-2.

0\ \textgreater \  \frac{1}{3}\times 0-2
\\
\\0\ \textgreater \ -2

A soccer team scores 12 points in 5 matches. They scored the same number of points in each of their first 3 matches and one more
NeX [460]

Answer:

2 points the first 3 matches then 3 points the last 2 matches

Step-by-step explanation:

12 points in 5 matches and the first 3 are all the same then the other 2 increased by 1 point

They got 2 points the first 3 matches then 3 points the last 2 matches

2 + 2 + 2 (first 3 matches) = 6

3 + 3 (last 2 matches) = 6

6 + 6 = 12
