Answer: Angle 3 and Angle 9
Step-by-step explanation:
The ball will hit the ground at 2 seconds.
Step-by-step explanation:
Given that,
The path of the ball = h(x)=−2x2+1x+6
Here,
x is the time while h is the height of ball.
When the ball will hit the ground, the height will become zero. Therefore,
h(x)=−2x2+1x+6
0 =−2x2+1x+6
or
2x2 -1x - 6 = 0
This is a quadratic equation, hence by applying quadratic equation formula:

here,
a = 2
b = -1
c = -6
Putting these values in formula, we get




x = 2, -3/2
As the time cannot be negative. Therefore, the ball will hit the ground at 2 seconds.
Your current balance if you started the day with $100 in your account is $73
First step is to calculate the total cash at bank
Using this formula
Total Cash at bank= Cash at bank + Deposit
Let plug in the formula
Total Cash at bank=$100+90
Total Cash at bank=$190
Second step is to calculate the amount debited
Debit amount=($60+$3)+($34+$20)
Debit amount=$63+$54
Debit amount=$117
Now let determine your current balance
Current balance=Total cash at bank-Amount debited
Let plug in the formula
Current balance=$190-117
Current balance=$73
Your current balance if you started the day with $100 in your account is $73

multiply 500 by 4 to know how much is needed in grams first
500×4 = 2000
convert 2000grams to kilograms
since 1000grams make 1 kilograms....then divide 2000 by 1000
which would give you 2000/1000
answer = 2kg of sugar
