In a trapezoid, the segment at the midpoint is the average of the other two bases.
In other words: YZ = (QR + TS) / 2
5x + 1 = ( (2x + 7) + 19 ) / 2
2(5x + 1) = 2x + 26
10x + 2 = 2x + 26
8x = 24
x = 3
YZ = 5x + 1
YZ = 5(3) + 1
YZ = 15 + 1
YZ = 16
Hope this helps!
2x+0.5 i think this is right
Answer:
Step-by-step explanation:
h(x) = 36 - 4.9x^3
Let x be 1.3
The question is not entirely clear. Looks like the iphone moved. Not only that, but the question is not really clear either. I'm taking it to mean that h is the distance from the GROUND to the ROCK after 1.3 seconds.
h(x) = 36 - 4.9(1.3)^2
h(1.3) = 36 - 4.9 * 1.3 * 1.3
h(1.3) = 36 - 27.719
h(1.3) = 8.28 m
The answer would be six because if you add them up it would equal 56 then divide that by 7 gives you a mean of 8. hope that helps
