step 1
Find out the slope WX
W(2,-3) and X(-4,9)
m=(9+3)/(-4-2)
m=12/-6
m=-2
step 2
Find out the slope YZ
Y(5,y) and Z(-1,1)
m=(1-y)/(-1-5)
m=(1-y)/-6
m=(y-1)/6
step 3
Remember that
If two lines are perpendicular
then
their slopes are negative reciprocal
that means
(y-1)/6=1/2 -----> because the negative reciprocal of -2 is 1/2
solve for y
2y-2=6
2y=6+2
2y=8
<h2>y=4</h2>
Answer:
1.5 cm/s
Step-by-step explanation:
The unit rate is the same as the slope.
To find the slope, we use the slope formula:

Using our points, we have
m = (9-0)/(6-0) = 9/6 = 3/2 = 1.5 cm/s
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
Answer:
the digit two is in tens... so a) is the answer
To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:

We can then use the pyramid formula to find the volume:

In this case,the volume will be:
10×_/69×1/3
=27.68874...
≈27.7 units^3
Hope it helps!
