Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:

Lets expand this in the form
, so we have:

We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:

We know a and b, let's find the seconds, x,

Hence,
1 seconds after being thrown, the stone reach its max height
That expression is written like so:
(5 + d)/(12 - w)
Answer :
- Total number of people in the room = 18
- Number of people with red hair = 2
- Number of people not with red hair = 18 - 2 = 16
- Probability of picking a person who doesn't have red hair =

Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
Answer: 8
Step-by-step explanation:
You have to divide 6.7/0.8 and you'll get your answer. She'll be able to use 8 full pieces.
Answer:
J'(-2,5)
K'(-7,5)
M'(-3.5,2)
L'(5.5,2)
Step-by-step explanation:
Please refer to the image attached to this answer.
Trapezoid JKLM is reflected over the x-axis, what do we notice about the ordered pairs of the original figure and the ordered pairs of its reflection over the x-axis is described below.
Point J , K L and M , when reflected over x axis , there distance from the y axis remains the same in second quadrant. the x coordinate becomes negative however the y coordinates remains the same.
The coordinates will be as shown in the image attached.
