Based on the ratio of boys/girls We can infer that the only possibility for Ellen's math class would be answer B. 14/21
Answer:
The distance travelled by ball is 98 units before it again reaches the same height from which it was thrown.
Step-by-step explanation:
The given parabolic equation is
Where, h is height of ball after covering x distance horizontally.
Put x=0, to find initial height of the ball.
Put y=5.5 in the given equation and find the values of x at which the height of ball is 5.5.
Take square root both sides.
The height of ball is 5.5 at x=0 and x=98.
Therefore distance travelled by ball is 98 units before it again reaches the same height from which it was thrown.

Or .20×30 and you'll get your answer
G(x) = 13
f(x) = 25
25{13(5)}= 1625
Answer:
y + 5 = -2(x - 7)
Step-by-step explanation:
The slope of the line y = (1/2)x + 4 is 1/2. Any line perpendicular to this one will have a slope which is the negative reciprocal of 1/2: -2.
Using the point-slope form, the desired equation is:
y + 5 = -2(x - 7)
