Answer:
x exponent 4 + 6y exponent 2 - y exponent 4
Step-by-step explanation:
To solve for the time an object takes to hit the ground, the equation
<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>
(-2*60/-9.8)^½ = 3.50 seconds.

So the 2nd answer is correct: 1 / 3^5
<em> 195 yards²</em>
- Step-by-step explanation:
<em><u>Area of rhombus (formula)</u></em>
<em>A = (d₁ₓd₂)/2</em>
<em>d₁ = 2ₓ7,5yd = 15 yd</em>
<em>d₂ = 2ₓ13yd = 26 yd</em>
<em>A = (15ydₓ26yd)/2</em>
<em>= 15ydₓ13yd</em>
<em>= 195 yards²</em>
90 degrees
