Answer: 5.22 seconds
<u>Step-by-step explanation:</u>
t represents time and y represents the height.
Since we want to know when the ball hits the ground, find t when y = 0
Ball 1 starts at a height of 109 --> h = 109
0 = -16t² + 109
16t² = 109
t = 5.22
Answer:
The age of Sarah is x. Four times the difference between 44 and x is 64 4(x–44) is 64. The total is equal to 64, the equation would be 4(x–44) =64
Step-by-step explanation:
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y^2 - 2 = 3y
5y^2 - 3y - 2 = 0
(5y + 2)(y - 1)
5y + 2 = 0 or y - 1 = 0
5y = -2 or y = 1
y = -2/5 or y = 1
Choose the correct conic section to fit the equation. x^2/36-y^2=1 Circle Ellipse Parabola Hyperbola
Solution:
The general equation of circle is:-
(x-h)²+(y-k)=r²
The general equation of ellipse is:-
The general equation of parabola is:-
y = a(x-h)²+k
The general equation of hyperbola is:-
The equation of conic section is: x^2/36-y^2=1
Hence, this is hyperbola.
Answer: Hyperbola Option (D)
