Answer:
Step-by-step explanation:
The finite set is in which we can count the elements which has finite number of elements
option 1 is not correct because we can not count the whole numbers they could extended upto infinite.
Option 2 is correct that is finite because condition is given that is natural numbers less than 100,000.
Option 3 is finite because we can count all letters of the alphabet.
Option 4 is not finite because all odd numbers can be extended upto infinity.
Option 5 is correct that is finite because world's population will be a finite number.
Option 6 is finite because it is empty set which is finite.
Option 2 multiple each side by -5
To solve this, simply switch the X and y variables within one equation, and upon doing so, see and check if it equals to the other equation.
f(X) = -X + 4/5
Y = -X + 4/5
X = (-Y+4)/5
5X = -Y + 4
-Y = 5X - 4
Y = -5x + 4
Yes, by looking at the second equation it is an inverse of the first one.
X^3 = 216
by taking cubic root for both sides
![\sqrt[3]{x^3} = \sqrt[3]{216}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%5E3%7D%20%3D%20%20%5Csqrt%5B3%5D%7B216%7D%20)
x = 6
Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .
