Answers
Answer:
speed of the rocket is 6feet
Step-by-step explanation:
Complete question
The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
Note that the average rate is also known as the speed
Average rate = h(3)-h(1)/3 - 1
h(3) = 3+70(3) - 16(3)^2
h(3) = 3 + 210 - 144
h(3) = 69
h(1) = 3+70(1) - 16(11)^2
h(1) = 3 + 70 - 16
h(1) = 73 -16
h(1) = 57
Average rate = 69-57/3-1
Average rate = 12/2
Average rate = 6ft/s
This shows that the speed of the rocket is 6feet

=4^7
(4^1 +4^-4)=4^(1-4)
=4^-3
4^7/4^-3,recalling about laws of indices if the exponentials are dividiy ,you subtract the powers give their base is equal

Prasad worked 15 hours this week and earned $195. Assuming he is paid by the hour, how much will Prasad earn next week if he is scheduled to work 12 hours?
Answers
Answer:
$156
Step-by-step explanation:
First you must find out the number of dollars Prasad receives per hour.
Since he earns $195 in 15 hours we can do 195/15 = 13 to find out the amount of dollars he earns per hour which is $13.
Next we must find out how much money he receives when he work for 12 hours so we simply do 13 (payment per hour) * 12 (amount of hours he works) which will give us $156!
This makes sense cuz 156 is a little bit less than 195 and ofc 12 is a little bit less than 15!
Prasad earn $156 next week if he is scheduled to work 12 hours
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Prasad worked 15 hours this week and earned $195
We have to find the amount earned by prasad for work 12 hours
Let us form an proportional equation.
Let x be the amount earned for 12 hours
15/195 = 12/x
Apply cross multiplication
15x=195(12)
15x=2340
Divide both sides by 15
x=2340/15
x=156
Hence, Prasad earn $156 next week if he is scheduled to work 12 hours

Un metro cúbico equivale a 1000 litros de capacidad y un decímetro cúbico a un litro ¿Cuántos litros cabrán en una piscina de 12,5 metros cúbicos?
Answers
Answer:
12,500 liters
Step-by-step explanation:
Given that
One cubic meter = 1000 liters
One cubic decimeter = 1 liter
We need to find out the number of liters fit in a 12.5 cubic meter
So
As it is mentioned that
One cubic meter = 1000 liters
So for 12.5 cubic meter
The number of liters would be
= 1000 × 12.5
= 12,500 liters
