Answer:
Option C
Step-by-step explanation:
WE are given a graph of exponential function and asked to find out of four functions which function the graph represents.
We find that any function of the form
passes through (0,1) for all a
Hence we cannot distinguish any thing from the point
Let us consider when x=1
Then first function will have point as (1,2.4)
II funciton (1,0.31)
III function (1,0.45)
IV funciton (1,1.8)
From the graph given we find that the point of y is less than 1. Hence it can be either II or III
Consider x=-1
Then II function has point as (-1,3.225) and III function has point as (-1,2.222)
From the graph we find that the graph satsified only the point (-1,2.2222)
Hence OPtion III is right
Answer:
55, 125 and 125
Step-by-step explanation:
In this question, we are asked to find the other 3 angles in an intersection.
Please check attachment for what the diagram of the intersection might look like.
The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.
since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]
These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.
Answer:
3 : 7
Step-by-step explanation:
Let the radii be 3x, 7x.
Circumference = 2πr, where r = radius
Thus, ratio of circumference:
2 × π × 3x : 2 × π × 7x
= 3 : 7
( as 2, π and x get cancelled out)
