Mathematics
1 answer:
raketka [301]3 years ago
6 0

Answer:

Step-by-step explanation:

height after x seconds = -16x² - 2x + 600

-16x² - 2x + 600 = 450

16x² + 2x - 150 = 0

8x² + x - 75 = 0

Quadratic formula

x = [-1 ± √(1² – 4·8(-75))] / [2·8]

 = [-1 ± √2401] / 16

 = [-1 ± 49] /16

 = 3, -3⅛

-3⅛ is an extraneous solution, so x = 3 seconds.

What is the 8th term of the binomial expansion (x + y)10?
melisa1 [442]

Answer:

120x^3y^7

We can use the Pascal's triangle to solve this question.

This pascal's triangle is shown in the Image below. To build the triangle, begin with the number 1 at the top, then continue placing numbers below it in a triangular pattern. In this way, each number are the numbers directly above added together. So, the expression is :

(x+y)10

After you do the steps you be left with:

120x^3y^7
