Answer:
The "top center" one
Step-by-step explanation:
-y=x+3
-Use the <em>slope-intercept form</em> to find the slope and y-intercept. (y=mx+b)
m=1 b=3
-Slope: 1 , y-intercept: 3
X | y
-3 | 0
0 | 3
Then you can use a graphing calculator if you'd like !
Answer:
a. 0.25
b. 0.4
c. 0.66 repeating
d. 0.75
Step-by-step explanation:
a. 1/4 is equal to one quarter which is 0.25
b. 2/5 is equal to 4/10 which equals 0.40 or 0.4
c. 2/3 is 0.6666666 and goes on forever so we would call that a repeating decimal
d. 3/4 is equal to three quarters which would be 0.75
i hope this helps :)
The correct answer is B.
0.5(4x + 12)
2x + 6
Question:
If the measure of arc CB is
units, what is the measure of ∠CAB?
Answer:
120°
Step-by-step explanation:
The figure has been attached to this response.
The figure shows a circle centered at A and has a radius of 4 units.
Also, the length of the arc CB (as given in the question) is
units.
The length <em>L </em>of an arc is given by;
L =
-----------------(i)
Where;
β = angle subtended by the arc at the center of the circle and measured in degrees
r = radius of the circle
From the question;
β = ∠CAB
r = 4 units
L =
<em>Substitute these values into equation (i) as follows;</em>
= 
=>
= 
<em>Cancel 8</em>
<em> on both sides</em>
= 
<em>Cross multiply</em>
3 x β = 360 x 1
3β = 360
<em>Divide both sides by 3</em>
<em />
<em />
β = 120°
Therefore, the measure of ∠CAB is 120°
