Given:
Angle AOC = 85°
Angle BOC = 2x + 10
Angle AOB = 4x - 15
Angle AOB + Angle BOC = Angle AOC
2x + 10 + 4x - 15 = 85
6x - 5 = 85
6x = 85 + 5
6x = 90
6x/6 = 90/6
x = 15
Angle AOB = 2x + 10 = 2(15) + 10 = 30 + 10 = 40
Angle BOC = 4x - 15 = 4(15) - 15 = 60 - 15 = 45
<span>Find the degree measure of Angle BOC and Angle AOB
</span>Answer is: <span>C. m= 45°; m= 40°</span>
Answer:
- y-intercept = 5
- common ratio = 1/2
Step-by-step explanation:
The y-intercept and the common ratio of an exponential function can be read from the equation. The form of the equation is ...
y = a·b^x
where 'a' is the y-intercept, and 'b' is the common ratio.
You have ...
y = 5·(1/2)^x
Comparing this to the above form, you can see that ...
y-intercept = 5
common ratio = 1/2
Answer is 4/7
You divide the length of C'D' over the length of CD
C'D'/CD = 8/14 = 4/7
The scale factor is smaller than 1, so C'D' is shorter than CD
Answer:
3
Step-by-step explanation:
The points they have in bold is probably a hint to the problem.
The points they have in bold are (1,2) on curve g which means g(1)=2
and (3,2) on curve f which means f(3)=2.
g(x)=f(kx)
We know g(1)=2 so if we replace the x's with 1, we get:
g(1)=f(k*1)
g(1)=f(k)
2=f(k).
Now we just need to solve f(k)=2 for k.
We know the point (3,2) is on f so f(3)=2.
If you compare:
f(k)=2
and
f(3)=2
then you should see that k=3.
