Answer:
5.5
Step-by-step explanation:
1, 2, 5, 5, 6, 8, 9, 9
5+6=11
11 divided by 2= 5.5
Answer:Linear pair and X is 23
Step-by-step explanation:
Answer:
(-24, -8)
Step-by-step explanation:
Let us recall that when we have a function f

<em>if the gradient of f at a given point (x,y) exists, then the gradient of f at this point (x,y) gives the direction of maximum rate of increasing and minus the gradient of f at this point gives the direction of maximum rate of decreasing</em>. That is

at the point (x,y) gives the direction of maximum rate of increasing

at the point (x,y) gives the direction of maximum rate of decreasing
In this case we have

and we want to find the direction of fastest speed of decreasing at the point (-3,-2)

at the point (-3,-2) minus the gradient equals

hence the vector (-24,-8) points in the direction with the greatest rate of decreasing, and they should start their descent in that direction.
Answer:
x=74
Step-by-step explanation:
If two tangent segments are drawn from the same external point, then the segments are equal.
Okay this one is simple once when you get an understanding of what they are asking. First divide the numerators by the denominators. 2/5=0.4 this is terminating because there are no numbers after it ends at 4. 7/45 is 0.15555556... this is repeating because it keeps on going. 5/99 is 0.05050505... repeating. Lastly 27/250 is 0.108 this is terminating because it stops. :) Hope this helps.
