Putting equation
0 = -16t² + 36t + 4
<span>0 = -8t² + 18t + 2 ← Complete the square to solve </span>
<span>-8(t² - 9t/2) = -2 </span>
<span>8(t² - 9t/4 + 81/64) = 2 + 81/8 </span>
<span>8(t - 9/8)² = 97/8 </span>
<span>(t - 9/8)² = 97/64 </span>
<span>t -</span><span> (t = 0) </span>
<span> (h = 0) at: </span>
<span>t = (9 + √97)/8 ≅ 2.356 seconds
hope it helps</span>
8+0.0+0.01+0.007 this is the answer
Answer:
320 students
Step-by-step explanation:
10,000=400+30x
10,000-400
9600=30x
9600/30
320=x
well add -6y to 6y which equals 0 then add 8y to 6y which equals 14y
now you have 13.02=14y
now you can divide 13.02 divided into 14 which equals 0.93
0.93 = y
Like terms have to have the same variables and the variables have to have the same powers.
3x and 6x are like terms.
3x and 6y are not.
4y^2 and 7y^2 are like terms.
4y^3 and 7y^6 are not.
2xy and 5xy are like terms.
2xy^2 and 5x^2y are not
2xy^2 and 5xy are not.
