<u>Change</u> of PE over a height of 10m = M G H = (10) (9.8) (10) = 980 joules.
When the box hits the bottom, it has 980 joules <u>less</u> PE than it had
before it started dropping.
(As well as 980 joules <u>more</u> kinetic energy.)
vertex: (-4, -6)
min or max? min
axis: y = -4
D: all real numbers
R: All real numbers greater than or equal to -6
I think triangular pyramid...............cause the base is triangular shaped.<span />
We have to simplify this as a product of fractions. Notice that the 6 has a negative sign, therefore, the result will be negative. We have then:
therefore, the simplified result is -2
4m + 23 + n
p + 3
Convert variables to their numbers
4(7) + 23 + 2
8 + 3
Simplify the expression
1. 28 + 23 + 2
8 + 3
2. 51 +2
8 +3
3. 53
8 + 3
4. 53
11
5. 53/11 = 4.82
