The correct answer of the given question above would be 8ft/sec. The minimum speed that the stone be thrown so as to reach a height of 49 feet is 8ft/sec. Consider this given solution here:
u^2 = 2x a x 1
<span>u^2 = 2 x 32 x 1 </span>
<span>u = 8 ft/sec
</span>Hope this answer helps and this is what you are looking for.
For 8/10:
16/20
24/30
64/80
for 5/2:
10/4
20/8
100/40
hope this helps
(3m - 4n - 7) - (8m + n - 6)
3m - 8m = - 5m
-4n - n = -5n
-7 - (-6) = -7 + 6 = -1
-5m - 5n - 1 is your answer
hope this helps
Answer:
A
Step-by-step explanation:
Answer:
66.4°
Step-by-step explanation:
To find the angle XYZ, we are to use sine rule. For this, we have to first find ∠Z.
Given that: ∠X = 90° (right angle), XY = 6 cm, YZ = 15 cm. Hence:

∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
90 + ∠Y + 23.6 = 180
113.6 + ∠Y = 180
∠Y = 180 - 113.6
∠Y = 66.4°
∠Y = ∠XYZ = 66.4°
