Answer:
Both Tom and Jerry will apart 176 miles in 2 hours .
Step-by-step explanation:
Given as:
Tom and Jerry moves in opposite direction
The speed of Tom = 38 mph
The speed of Jerry = 50 mph
Let The distance cover by Tom = x mile
The distance cover by Tom = ( 176 - x ) miles
Time taken by both are same = T hour
Or, Time taken by Tom
T = ... 1
∴ x = 38 T
And Time taken by Jerry
Or, T =
So , put the value of T from 1
=
Or, 50 × x = ( 176 - x ) × 38
So 50 x + 38 x = 6688
Or, 88 x = 6688
∴ x = = 76 mile
So, From, eq 1
T =
or, T = = 2 hours
Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer
- This is the general formula and the period is 2π/B
Now our given function
On comparing we get
- A=8
- B=5π
- C=3π/2
- D=-9
Period:-
Answer:
(-∞,7) U (7,∞)
Step-by-step explanation:
f(x)= x+2
g(x) = x-7
Here we have x-7 in the denominator
To find domain we set the denominator =0 and solve for x
x-7=0
Add 7 on both sides
x=7
x=7 makes the denominator 0 that is undefined
So we ignore 7 for x
Hence domain is
(-∞,7) U (7,∞)
