Answer:
102 actually just add it up
Step-by-step explanation:
add it up
A.
y = 7 - |x| = 7 - 2 = 5
b.
y = x² - 1 = 2² - 1 = 4 - 1 = 3
c.
y = √(x + 14) = √(2 + 14) = √16 = 4
Answer:
The total number of possibilities are 60.
Step-by-step explanation:
Given:
There are 6 digits and 3,7,9 are odd ones.
To Find:
How many possibilities are there for the rock's age
Solution:
Here condition is that number should start with odd digit
so there 3 number only as odd(3,7,9)
So it leaves 3 repeating numbers i.e.2
So permutation of 5 numbers with 3 odd numbers
So possible arrangement will be
nPr
n=5 ,r=3
So 5P3=5!/3!
And finally for all possibilities as
=3*(5!/3!)
=3*(20)
=60
9514 1404 393
Answer:
21 miles per hour
Step-by-step explanation:
Let w represent the wind speed. Then the travel time is ...
400/(329 +w) = 352/(329 -w)
400(329 -w) = 352(329 +w)
(352+400)w = 329(400 -352)
w = (400 -352)/(400 +352)·329 = 48/752·329 = 21
The wind speed is 21 miles per hour.
