Explanation: The distributive property tells us when there's a number outside a set of parenthses, you can multiply it times each of the terms that are inside the set of parenthses and then add those products together.

So in this problem, we can multiply 5(4) + 5(8)

which simplifies to 20 + 40 which equals 60.

Okay, so what you need to figure out is that how many years in between 21 1/4 and 37 there are based on the amount the tree grows a year. So, 1 3/4 times 9 is 15.75, and this added to 21 1/4 is 37. This means that it will take the tree 9 years to grow from 21 1/4 ft to 37 ft.

Step-by-step explanation:

Okay. Are you taking calc? Dv/dt =d/dt(L(t)^3)=d/dt[(sqrt(14)+2t)^3]= 6(Sqrt(14)+2t)^2)=44. We defined t=0 to be time at which length is sqrt(14). Does that work?

Find three consecutive integers such that the sum of the first and twice the second is 110 minus three times the third
Serggg [28]

First off, consecutive integer and  can be written as n, n+1 and n+2

(try putting a number in for n if it does not make sense yet)

The sum of the first and twice the second would be n+2(n+1)

So, our equation becomes

n+2(n+1)=110-3(n+2)

n+2n+2=110-3n-6

3n+2=104

6n=102

n=17

so, our three term are 17,18 and 19

A model rocket is launched with an initial upward velocity of 30 m/s. The rockets height (in meters) after t seconds is given by
daser333 [38]

9514 1404 393

Answer:

  t = 3-√7 and 3+√7 seconds after launch

Step-by-step explanation:

You want to find the values of t that make h=10.

  10 = 30t -5t^2

  t^2 -6t = -2 . . . . . divide by -5

  t^2 -6t +9 = 7 . . . add 9 to complete the square

  (t -3)^2 = 7 . . . . . write as a square

  t -3 = ±√7 . . . . . . take the square root

  t = 3 ±√7 . . . . . . values of t for which height is 10 meters

__

These values are about 0.354 seconds, and 5.646 seconds.
