The height of the ball at ground level would be 0 feet.
Set h to 0 and solve for t:
Rewrite the equation as
-5t^2 -2t +49 = 0
Factor -1 out of the equation to get:
5t^2 + 2t -49 = 0
Use the quadratic formula:
-b +/- sqrt(b^2 -4(ac) / 2a
Where a = 5, b = 2 and c = -49
The quadratic formula becomes:
-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)
Simplify to get :
T = -2 +/-sqrt246 / 10
T = 2.936 and – 3.336
Since the time has to be a positive value t = 2.936 seconds.
Rounded to the nearest hundredth = 2.94 seconds.
Answer:
it will be c because you see the points on the grid if its wrong my bad
Step-by-step explanation:
Answer:
14. T (0.75,-1)
U (0.75, 1.25)
V (-0.75, 1.25)
15. W (-0.75, -1)
16. Coordinates with x =0 are on the y-axis not the x-axis.
Step-by-step explanation:
14. The (x,y) points are written using the x value and y value for the coordinate.
T (0.75,-1)
U (0.75, 1.25)
V (-0.75, 1.25)
15. The fourth vertex of the rectangle called W will need to be at the same level as T and lined up with V.
W (-0.75, -1)
16. Coordinates with x =0 are on the y-axis not the x-axis.
Answer:
its C
the increasing part means when y axis is increasing,you can observe it thru that img
Answer:
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3).
Step-by-step explanation:
xy = (x + y)^4
Using implicit differentiation:
x dy/dx + y*1 = 4 (x + y)^3 * (1 + dy/dx)
x dy/dx + y = 4 (x + y)^3 + 4 dy/dx (x + y)^3
x dy/dx - 4 dy/dx (x + y)^3 = 4 (x + y)^3 - y
dy/dx( x - 4(x + y)^3) = 4 (x + y)^3 - y
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3)
