The answer is 474 i believe
1.67 is your answer 13.98 - 3.96=10.02 10.02 divided by 6 = 1.67
Hope I helped
C is the rigth answer because all the other three has two x values in common. :)
Answer:
<em>after 4seconds</em>
Step-by-step explanation:
Given the height, h , in feet, of the football above the ground after t seconds expressed by h ( t ) = − 8 t^2 + 32 t, the height of the ball on the ground is 0feet.
Substitute h(t) = 0 into the expression and calculate t;
h ( t ) = − 8 t^2 + 32 t
0 = − 8 t^2 + 32 t
8t² = 32t
8t = 32
Divide both sides by 8
8t/8 = 32/8
<em>t = 4s</em>
<em>Hence the football hits the ground after 4seconds</em>
Answer:
-0.25
Step-by-step explanation:
Coordinates of C = 
Coordinates of D = 
Let Coordinates of A= (x,y)
Since A point is located 1/4 the distance from C to D
So the remaining distance from point A to D is 3/4
Thus the ratio of CA : AD = m:n=1:3
Now to find points of A we will use section formula i.e.
Substituting the values:
Thus Find the x value for the point that is 1 over 4 the distance from point C to point D is -0.25
Hence option a is correct
