The height in feet,h , of a model rocket t seconds after launch is given by the equation h(t) = 3+70t-16t^2.

Answers

Answer 1

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

Answer 2

Answer:

If you're looking for the answer for edge, its;

B. The rocket is at a greater height when t = 3 than when t = 1.

The school that Shawna goes to is selling tickets to a spring musical. On the first day of ticke sales the school sold 7 adult tickets and 7 student tickets for a total of $91. The school took ir $170 on the second day by selling 14 adult tickets and 12 student tickets. Find the price of an adult ticket and the price of a student ticket.​

Answers

Answer:

price of an adult ticket = a = $7

price of a student ticket = s = $6

Step-by-step explanation:

price of an adult ticket = a

price of a student ticket = s

7a + 7s = 91 (1)

14a + 12s = 170 (2)

Multiply (1) by 2

7a + 7s = 91 (1) × 2

14a + 14s = 182 (3)

14a + 12s = 170 (2)

Subtract (2) from (3) to eliminate x

14s - 12s = 182 - 170

2s = 12

s = 12/2

s = 6

Substitute s = 6 into (1)

7a + 7s = 91 (1)

7a + 7(6) = 91

7a + 42 = 91

7a = 91 - 42

7a = 49

a = 49/7

a = 7

price of an adult ticket = a = $7

price of a student ticket = s = $6

A tax exempt employee benefit is usually more adavantages to the employee than a tax deferred benefit

Answers

Answer:

Step-by-step explanation:

Yes, it is, more or less. This is because with a tax-deferred account, tax savings are gotten when you make contributions, but when it then comes to a tax-exempt account, the withdrawals are instead free of tax during retirement.

In a tax-deferred account, you can make immediate tax deductions as much as the full amount of your intended contribution, but then, subsequent withdrawals from the same account will be taxed at the normal income rate.

On the other hand, tax-exempt accounts don't deliver a tax benefit, particularly when you contribute to the them, they provide tax benefits that comes much later

A suit is on sale for 71% off. The sale price is $278.40.
What is the regular price?

Answers

Answer:

it looks like the answer is $476.06.

Step-by-step explanation:

i got this answer because we already know the sale price. We need to find the regular/ original price of the suit. So in order to do that all you have to do is:

278.40 * 71%= 197.664

now add both together because 197.664 is how much the discount was. So, now add both together. 278.40 + 197.664. Now this gives you, 476.064, round it and you should get $476.06 for the original/regular price.

Si un capital de 6800 soles se presta a 12% anual, durante a años y 19 días, ¿Qué interés producirá?

Answers

El número de años no se da de forma exhaustiva. Usando un valor hipotético

Respuesta:

Por favor, consulte la explicación.

Explicación paso a paso:

Suponga que el número de años es igual a 1 año 19 días

Convertir en años; 19 días es igual a 19/365 = 0,0520547; por lo tanto, 1 + 0.0520547 = 1.0520547 años

Recuerde la fórmula de interés simple:

Interés = principal * tasa * tiempo

Interés = 6800 * 0,12 * 1,0520547

Intereses = 858,4766352

Por tanto, si el plazo es de 1 año 19 días; interés = 858.4766352

Si el número de años en el período es diferente, simplemente siga el mismo paso para convertir los días y sume al número exacto si los años se dan.

The bike Razi wants to buy costs

hours. He has also mowed the lawn 5 times.
Has he earned enough money to buy the
bike?

Answers

Answer:

Not enough information

Step-by-step explanation:

So, we first know that the bike costs 250 dollars. We also know that he babysat for 15 hours, and mowed the lawn 5 times. However, we do not know how much money he has, or how much he made. Sure, doing extra chores could of made him money, but in this question it doesn't say how much money he made. Therefore, we cannot answer this question because, although we have the value of the bike's cost, we do not know how much Razi has. Hope this helps you!
