Answer:
all done bud, I'm just here for the extra points :D
the sine function is a many-to-one function and therefore has no inverse function.
However if the domain is restricted to -90° ≤ x ≤ 90°
Then the function is one-to-one for this domain
Thus, 
x is defined as the angle such that - π/2 ≤ x ≤ π/2
5π/6 is therefore outwith the domain
Answer:
y = 50x + 3.5
Step-by-step explanation:
Given:
Distance already covered = 3.5 miles
100 miles covered in 2 hour
FInd;
Equation of given scenario
Computation:
Assume;
Total miles covered = y
Total number of hours = x
Speed of car = 100 / 2
Speed of car = 50 miles per hour
Total miles covered = Distance already covered + [Speed of car][Total number of hours]
y = 3.5 + [50][x]
y = 50x + 3.5
81/4
Step-by-step explanation:
9=4x/9
81=4×
x=81/4
adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power
base of log is raised to power of element after =
element in log is then equal to log base raised to power
solve resulting equation
<u>Answer</u>:
[ ( 2 x^2 - x - 5 ) ] / [ ( x + 2 ) ( x - 3 ) ]
option c). is correct.
<u>Step-by-step explanation</u>:
( x + 1 ) / ( x + 2 ) + ( x - 1 ) / ( x - 3 )
= > [ ( x + 1 ) ( x - 3 ) + ( x - 1 ) ( x + 2 ) ] / [ ( x + 2 ) ( x - 3 ) ]
= > [ ( x^2 - 3 x + x - 3 + x^2 + 2 x - x - 2 ) ] / [ ( x + 2 ) ( x - 3 ) ]
= > [ ( 2 x^2 - x - 5 ) ] / [ ( x + 2 ) ( x - 3 ) ]
Hence we get required answer!
