Answer:
Y=1/3
Step-by-step explanation:
X=k/y
So let's make k the subject of formula
k=xy
x=1,y=5
So let's substitute
k=1×5
k=5
So we are to determine the value for y when x is 15
So let's solve
Y=k/x
Y=5/15
Y=1/3
Y=0.333333~0.3
The functions which are even are symmetric to y-axis. By even functions, it means that f(x) = f(x) for all the domain values. Thus even functions for example, x^2, 1+x^2, cosx, x^4 all follow the conditions i.e. f(x) = f(x) and thus they are symmterical to y-axis.
Answer:
Step-by-step explanation:
Chords having equal measures are equidistant from the center of the circle.
Since, VW = XY
Therefore, ZP = ZR = 15 units
A perpendicular line drawn from the center of a circle to the chord is the bisector of the chord.
VR = WR = 20 units
By applying Pythagoras theorem in ΔZRV,
ZV² = ZR² + VR²
ZV² = (15)² + (20)²
ZV = √(225 + 400)
ZV = √625
ZV = 25 units
Therefore, measure of radius ZV = 25 units.
VW = XY [Given]
Therefore, XY = 2(20)
= 40 units
Well, lets think about this. We need to ask our self how many seconds are in one minute. There are 60 seconds in 1 minute. We know he did 4 laps in 5 minutes and 40 seconds. You can change the minutes to seconds by multiplying 60 * 5 = 300 seconds. So 5 minutes = 300 seconds. Now just take the 40 seconds and add it to the 300 seconds, which will give you 340 seconds. So John ran 4 laps in 340 seconds. B wants to know how many seconds it took John per lap...We can find this by dividing 340 by 4 340/4 = 85.
A) 340 seconds
B) 85 sec/lap
