Mathematics
1 answer:
Pavlova-9 [17]4 years ago
5 0

Answer:

6 seconds

Step-by-step explanation:

h(x) = 0 m , when the ball is on the ground.

h(x) = - (x-2)² + 16

0 = - (x-2)² + 16

(x-2)² = 16

√(x-2)² = +/- √16

(x-2) = 4  ,        (x-2) = - 4

x - 2 = 4  ,         x = -2

x = 6

We can use only positive solution.

Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1030 was collected. First
Marrrta [24]

Answer:

170 tickets.

Step-by-step explanation:

Write formulas for the question.

N_2+N_3=400

2N_2+3N_3=1030

Then use substitution.

N_2=-N_3+400

2(-N_3+400)+3N_3=1030

-2N_3+800+3N_3=1030

N_3=230

So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

N_2+230=400\\N_2=400-230\\N_2=170

what is the final amount of 17.50 that is put into a saving account with 4 annual interest rate compounded yearly for 25 years?
pickupchik [31]
To find the total amount, you will use the formula for finding compounded interest.  This means you will be paid interest on top of the interest you have earned each year.

A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years

A = 17.50(1 + 0.04)^25
A = $46.65

This person would have $46.65 after 25 years.
