Answer:
The answer is C i.e y = 3.25 x + 4.60
Step-by-step explanation:
Given the graph in which the Javier made a scatter plot to show the data he collected on the growth of a plant.
Now, we have to choose the equation which best represents Javier's data.
The graph shown does not pass through origin therefore intercept can not be equal to 0. hence solution A discarded.
The graph of rest of three solutions attached and the points which shown in the graph match to the points on the graph of solution third as shown. Hence, The answer is C i.e y = 3.25 x + 4.60
Answer:
See below
Step-by-step explanation:
Y component of velocity is 70 sin 30°
y position = 3 + 70 sin 30° * t - 1/2 a t^2
when the ball hits the ground y = 0
0 = 3 + 70 sin 30° t - 1/2 (32.2)t^2
- 16.1 t^2 + 35t + 3 = 0
Use Quadratic Formula to find t = <u>2.26 seconds</u>
Horizontal component of initial velocity
70 cos 30° distance horizontal = 70 cos 30° * t
= 70 cos 30° (2.26) =<u> 137.0 ft</u>
12*14*3= 504 square feet
504/42= 12
C. 12 rolls
The correct answer is 8 1/3. Hope this helps!!
