M∠YVZ = 90°
The measure of the angle formed by 2 chords that intersect inside the circle is 1/2<span> the sum of the chords' intercepted arcs.
(arcYZ+38)/2 = 90
arcYZ + 38 = 90*2
</span>arcYZ + 38 = 180
arcYZ = 180 - 38
arcYZ = 142°
I think the answer would be -14
Answer:
The rate of change for the given function is 6.
Step-by-step explanation:
Given function is:
The interval on which we have to find the rate of change is:
1≤x≤2
Here
a = 1
b = 2
We have to find the values of function on both points
Putting 1 in place of input (x)
Putting x = 2
The rate of change is calculated by using the following formula
Hence,
The rate of change for the given function is 6.
Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
