Answer:
<em>t = 5 seconds</em>
Step-by-step explanation:
We must solve the equation of movement of the ball as a function of time in seconds.
We must find how many seconds it takes until the ball touches the ground. When the ball touches the ground, the height b (t) = 0
Then we equate the equation to zero and solve for t.

Use the quadratic formula.
Where


We take the positive solution
<em>t = 5 seconds</em>
Answer:
(±1, -2)
Step-by-step explanation:
The co-vertices are the end points of the minor axis. The center is at (0, -2) and the minor axis is 2 units long, so the co-vertices are ...
(-1, -2) and (1, -2)
C.
Add all cups of sugar, which would be 20. Divide it by 5 (the number of students in the class). 20/5 = 4.
Answer: 5/6,2 2/3, 2 1/2
Step-by-step explanation:
Answer:
<h2> 2 trips</h2>
Step-by-step explanation:
first, we need to model an expression, the solve, say
let the total amount charged by taxi be y
and let the number of kilometers be x
y=2x+9
given that uber charges $5
then the number of taxi trips that will equal urber charge is
y=2x+9=5
5=2x+9
solving for x we have
2x+9-5=0
2x+4=0
2x=-4
x=-2
x=2 (x cannot be negative)
