Hello :
find : g(x) if <span> f(g(x))=3x-7 and f(x)=1/3x2

</span> f(g(x)) = 1/3(g(x))2 = 3x-7
solve : 1/3(g(x))2 = 3x-7
(g(x))2 = 9x-21
g(x) = <span>√(9x-21)</span>

Olegator [25]

The total bill amount before the service fee is given as $45.
We are given that the tip she wants to leave is 15% of the bill amount, this means that:
tip value = 0.15 * 45 = 6.75$

The total bill would be the summation of the original bill and the tip value she left.

Total bill amount = 45 + 6.75 = 51.75$

g100num [7]

Answer:

The correct option is C

Step-by-step explanation:

Given the circumference of circle which is 54 cm and also the measure of arc XY is 120°

we have to find the expression for arc length of XY

The arc length can be calculated by the formula

$\frac{\theta}{360}\times 2\pi r$

$\frac{\theta}{360}\times circumference$

$\frac{120}{360}\times 54$

Hence, option C is correct
