Answer:
Step-by-step explanation:
First of all we have to use cos.
cos (30) is √3/2
so (7√3)/(√3/2)
7√3 * 2/√3 = 14√3/√3
(14√3 * √3 )/ 3
42/3 = 14
<u>I AM ASSUMING THIS QUESTION IS NON CALC.</u>
The answer should be 14.
Step-by-step explanation:
Let f be a function having domain in the set X, and range in the set Y. Then f would be invertible if there exists a function g having domain Y and range X, such as:
In other words, the function is applied to an input x, and gives an outcome of y, then its inverse function, let say , can be applied to y to give the result of x.
In other words,
y = f(x) if and only if x = g(y)
For example, considering the function
the inverse is:
$91/ 7 = $13 per dog
$117/$13 = 9 dogs
He washed 9 dogs
Use DESMOS and then take the points that are given and then plug them into your equations to show your work.
Desmos helps all equation problems that you need solved because it not only solves it, but also has it graphed with marked points.
It helped me through highschool.
