Answer:
8.333
Step-by-step explanation:
50 (times)/ 6 (amount of numbers possible on cube)
We have that
y = 225-16t²
we know that
<span>the ball hit the ground when y=0
the point when y=0 is the x intercept of the graph
so
find the value of t for y=0
y=0
</span>y = 225-16t²------> 0=225-16t²
16t²=225-------> t²=225/16----------> t=√(225/16) -----> t=15/4 sec
t=3.75 sec
the answer is
t=3.75 sec
see the attached figure
Average speed = total distance/ time taken
= 200/5 = 40 miles per hour.
What seems like like the best real life assumption? I think that's what it's after. 5ft the height of a person, 9ft way taller than a human... etc.
Answer: The equation of the line in slope-intercept form will be
y = (7/4)x + b
Since the line passes through the point (8,-2), plug in the values of the point into the equation to find b.
-2 = (7/4)(8) + b
-2 = 14 + b
-16 = b
The equation of the line is
y = (7/4)x - 16
In standard form,
-(7/4)x + y = -16
Multiply both sides of equation by -4.
7x - 4y = -64
Step-by-step explanation: hope this helps :)
