Part 1: the function would be
h(t)= -16t^2+15t+6.5
Part 2: using the same steps it stated on the calculator
x=1.26
Part 3: by using t= -b/(2a) 15 as b and -16 as a makes it
t= 15/32
Part 4: You then put 15/32 in for t in the equation making the maximum height
10.02
IDK IF THIS IS RIGHT BUT IVE SPENT ALL DAY ON THIS
Hi!
If we multiply the top equation by (-2), then we can cancel out the y's.
-2(2x + 5y = 15)
-4x - 10y = -30
Now we add the second equation and our new equation together, and get:
x = 5
Now, we plug this in to one of the other equations
2(5) + 5y = 15
distribute
10 + 5y = 15
subtract 10 from both sides
5y = 5
divide both sides by 5
y = 1
Therefore, your answer is (5, 1)
Have a great day! :D
Answer:
Rate = 10%
Step-by-step explanation:
Given:
Amount deposit = 25,000
Amount get = 26,250
Time = 6 month = 6 / 12 = 0.5 year
Find:
Rate
Computation:
Interest = Amount get - Amount deposit
Interest = 26,250 - 25,000
Interest = 1,250
Interest = P x R% x T
1,250 = 25,000 x R% x 0.5
Rate = 10%
