Answer:
No. The reciprocal of a function is rarely the same as the inverse of the function.
Step-by-step explanation:
tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.
tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.
The attached graph compares the two functions.
The answer is 84%. This is because to get a percentage out of 100% you need to have 100 in your total so you multiply 50 *2 to get 100 and since you changed the 50 you also have to change your 42 by the same equation. So 42*2 is 84. Hope this helped please comment if you need clarifying.
378. Comparing the each batch, there is a difference of 18 for each batch. So 7*18= 126, then add that to 252; you'll get 378.
(ex 198-180=18; 216-198=18; etc)
hope that helps
Answer: 16 gallons
Step-by-step explanation:
Since we are given the information that 1/4 of the gas is left, it simply means that (1 - 1/4) = 3/4 has been used.
The tank was filled and this was 12 gallons of gas.
Let the gas that the tank hold be represented by x. Therefore,
3/4 of x = 12
3/4 × x = 12
0.75x = 12
x = 12/0.75
x = 16
The tank holds 16 gallons of gas.
