In order: 32°, 78°, 71°, 54° , 154°, 113° , 81° , 77° , 91° , 83° , 159° , 86° hope this helps just color in order of the degrees given and it will lead you to the end.
Answer:
B
Step-by-step explanation:
The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.
0 = - 16t^2 + 255 Set up the equation
- 255 = - 16t^2 Divide by -16
15.9375 = t^2 Switch
t^2 = 15.9375 Take the square root of both sides.
sqrt(t^2) = sqrt(15.9375)
t = 3.992 seconds
The closest answer is B
At x-intercept, y value = 0,
For t(x), x = 1 when y = 0, i.e. x-intercept = 1
for 3x - 2y + 6 = 0, when y = 0,
3x - 2(0) + 6 = 0
3x + 6 = 0
3x = -6
x = -6/3 = -2
i.e. x-intercept = -2
Therefore, t(x) has the highest x-intercept of 1.
Yes -5/2 is lest than -2
(-5)/2 < -2
-2.5 < -2
true
