Answer:
The measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°
Step-by-step explanation:
Here, the diameter of the circle = 6 m
Diameter = 2 x RADIUS
So, radius = D / 2 = 6 / 2 = 3 m
Also, the length of the arc = ( ) meters
Putting π = 3.14, we get
The length S of the arc =
or, S = 7.85 m
Let us assume the arc subtends angle Ф at the center of the circle.
⇒ S = r Ф
or, Ф =
⇒Ф = 2.61 radians
Now, 1 Radian = 57.2958 Degrees
⇒ 2. 62 Radian = 2.61 x ( 57.2958 Degrees) = 149.542 °
or, Ф = 149.542°
Hence, the measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°

Answer:
4. Option 3rd.
Step-by-step explanation:
In this question, three options are given.
We need to describe the same situation.
First option: y = 3 + 6x
this equation represent the equation of a line. In that line all the points are related with each other with same relation.
So, this equation describe the same situation.
Second equation:
y is two more than six times x.
We write this situation in equation form.
y = 6x + 2
this is also describe the same situation.
Third option:
this table shows the x-y relation table.
Here no two points are describe the same situation.
So, option 3rd doesn't describe same situation.
Question 5:
Please share the options
Answer:
23$ is left on his pass
Step-by-step explanation:
9x3=27 50-27=23
I think this is suppose to be
x y
2 1400
4 1000
you see at 2 hours they have 1400 left and at 4 hours they have 1000 feet left.
first we need y intercept or b since we will put it in y=mx+b form
so at x= 0 whats y. Based on this every 2 hours you climb 400. so go back from x=2 to x=0 would make 1000 into 1800 feet left
so at x hours you have 1800 left
y - intercept is (0, 1800) or +1800
now we need slope
difference in y / difference in x
diff in y = 1400-1000 = 400
diff in x = 2 - 4 = -2
difference in y / difference in x = 400/-2 = -200 is the slope
y=mx+ b for
y=-200x+1800
