T=3-√ 43/2=-1.63 and 3+√ 43/2=7.63
and since time can't be negative, it hits the ground at 7.63 seconds.
and then for 3 there are two steps. Use <span>t=−<span>b<span>2a</span></span></span> to find the time of max height. Then plug that time into the h(t) equation
the same values you used in the quadratic equation a = -16, b = 96, c = 200
<span>t=−<span>96<span>2(−16)
344 is the answer.</span></span></span>

<em>What percentage of 85 is 10?</em>
<em></em>
<em></em>
<em>(These are just some tips)</em>
<em> ↓↓↓</em>
<em>Take the number and multiple it by 85. Then multiply that by . 01.</em>
<em>To calculate 10 percent of a number, simply divide it by 10 or move the decimal point one place to the left. For example, 10 percent of 230 is 230 divided by 10, or 23.</em>

Answer:x= 45°
Step-by-step explanation:
The value of angle LKN is 75°becausw the theorem vertically oposite angles
Then the value of angle LPN is 45° because figure LKNP is a rectangle so the sum of the angles should be 360°so 120°+120°+75°+angle LPN is 360°so the value of angle LPN is 45°
The value of x is also 45° because of vertically oposite angles theorem
