Answer:
<em>( About ) 1.77 seconds; Option B</em>
Step-by-step explanation:
We are given the equation h ( t ) = - 16t^2 + 50, so in order to determine the time let us determine the x - intercept for y ⇒ 0;
- 16t^2 + 50 = 0,
- 16t^2 = - 50,
t^2 = 25 / 8,
Thus t ⇒ √ ( 25 / 8 ), and t ⇒ - √ ( 25 / 8 ),
t ⇒ ( 5√2 )/ 4, and - ( 5√2 )/ 4,
But time is represented only by a positive value, thus
t ⇒ ( 5√2 )/ 4 = 1.767766953......., ( About ) 1.77 seconds
<em>Answer; ( About ) 1.77 seconds; Option B</em>

Answer:
D. 3 to 4
Step-by-step explanation:
The ratio ...
blueberries : strawberries = (1/2) : (2/3)
can be changed to a ratio of integer by multiplying by the least common denominator: 6.
= 6(1/2) : 6(2/3) = 3 : 4
Step by step explanation
<u>let x be the number of minutes and y be the total charges per month</u>
<em>A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee. </em>
<em>y=0.02x+10</em>
<em> </em>
<em>B. Sandra's cell phone plan charges seven cents a minute. </em>
<em>y=0.07x</em>
<em />
<em>C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month.</em>
<em>y=0.05x-5</em>
<em />
<em> D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.</em>
<em>y=0.06x+5</em>
