If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'
Sever21 [200]

Answer:

Step-by-step explanation:

Reflection across the y axis changes the x value.

Reflection across the x axis changes the y value.

This is counterintuitive, but it is correct.

A'

(-1,6)

B'

(-2,1)

C'

(-5,2)

Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction

The height of a free falling object at time t can be found using the function, h(t) = - 12t2 + 36t. Where h(t) is the height in
never [62]
For this case we have the following equation:
 h (t) = - 12t2 + 36t
 When the object hits the ground we have:
 - 12t2 + 36t = 0
 We look for the roots of the polynomial:
 t1 = 0
 t2 = 3
 Therefore, the time it takes the object to hit the ground is:
 t = 3 s
 Answer:
 
the time when the object hits the ground is:
 
t = 3 s

Order of Operations rules require that we do the division first:

-0.48      48

-------- = --------- = 0.3

-1.6        1600

Then we combine 11.68 ad 0.3, obtaining 11.93.

A class of 20 boys and 15 girls is divided into n groups so that each group has x boys and y girls. Find x, y and n. what values
melamori03 [73]
20 = 2 x 2 x 5
15 = 3 x 5

common divisor (CD) of 20 and 15 is 5 so n should be 5 and each group has 4 boys and 3 girls.

If there are more than one CD, then there are more than one answer.

If they ask for the largest number of groups, greatest common divisor (GCD) will be the answer.
