Answer: you can not form a triangle with side lengths
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
Choice D, x = 9
Discussion:
Triangles EFG and EDG are congruent by SAS.
* Side = they both have a side of length 13.
* Angle = base angles F and D are equal as the triangles are isosceles.
Because of that, angles FEG and DEG are equal
*Side = they both share EG
Hence corresponding parts are equal, so FG = DG or
5x - 17 = 3x + 1 => (adding 17 to both sides)
5x - 17 + 17 = 3x + 1 + 17 =>
5x = 3x + 18 => (subtract 3x from both sides)
5x -3x = 18 =>
2x = 18 =>
x = 9
which is choice D

H(t) = -16t² + 60t + 95
g(t) = 20 + 38.7t
h(1) = -16(1²) + 60(1) + 95 = -16 + 60 + 95 = -16 + 155 = 139
h(2) = -16(2²) + 60(2) + 95 = -16(4) + 120 + 95 = -64 + 215 = 151
h(3) = -16(3²) + 60(3) + 95 = -16(9) + 180 + 95 = -144 + 275 = 131
h(4) = -16(4²) + 60(4) + 95 = -16(16) + 240 + 95 = -256 + 335 = 79
g(1) = 20 + 38.7(1) = 20 + 38.7 = 58.7
g(2) = 20 + 38.7(2) = 20 + 77.4 = 97.4
g(3) = 20 + 38.7(3) = 20 + 116.1 = 136.1
g(4) = 20 + 38.7(4) = 20 + 154.8 = 174.8
Between 2 and 3 seconds.
The range of the 1st object is 151 to 131.
The range of the 2nd object is 97.4 to 136.1
h(t) = g(t) ⇒ 131 = 131
It means that the point where the 2 objects are equal is the point where the 1st object is falling down while the 2nd object is still going up.
