A toy rocket is launched from a platform 33 feet above the ground at a speed of 83 feet per second. The height
of the rocket in feet is given by the polynomial -167 + 83t + 33, where t is the time in seconds. How high will
the rocket be after 3 seconds?
HELP ASAP
Answers
Answer:
138 feet
Step-by-step explanation:
plug "3" into the expression by replacing "t" with "3"
-16t^2+83t+33
-16(3)^2+83(3)+33 (remember PEMDAS)
=-16(9)+249+33
=-144+282
=138 (I hope this helps)

Step-by-step explanation:
The right angle is egual to 180-39-v, so it is: v-141
U now that the sum of the internal angles of a triangle is 180°.
180 = (v-48)+(v)+(v-141)
180 = 3v - 180
3v = 360

2. There are 35 men and 50 women running a race. What is the ratio of the number of female runners to the total number of runners? Answer:____________________________________
Answers
Answer:
10 : 17
Step-by-step explanation:
Male runners = 35
Female runners = 50
Total runners = male runners + female runners
= 35 + 50
= 85 runners
What is the ratio of the number of female runners to the total number of runners?
Ratio of the number of female runners to the total number of runners = number of female runners : total runners
= 50 : 85
= 50 / 85
= 10/17
= 10 : 17
Ratio of the number of female runners to the total number of runners = 10 : 17

9000 dollars Is places in an account with an annual interest rate of 7.75%. How much will be in the account after 18 years, to the nearest cent?
Answers
Answer: $21555
Step-by-step explanation:
First, we need to know the interest generated on the money saved. This will be:
= Principal × Rate × Time
= $9000 × 7.75% × 18
= $12555
The amount in the account after 18 years will then be:
= Principal + Interest
= $9000 + $12555
= $21555
