Given the parent functions f(x) = 5x - 1 and g(x) = 3^x - 9 what is g(x) - f(x)?
Andre45 [30]
G(x) - f(x) means subtracting the value of function f(x) from the value of function g(x). The steps of the solution are listed below:

g(x)= 3^{x}-9 \\  \\ 
f(x)=5x-1 \\  \\ 
g(x)-f(x)=  3^{x}-9-(5x-1) \\  \\ 
g(x)-f(x)=3^{x}-9-5x+1 \\  \\ 
g(x)-f(x)=3^{x}-5x-8

The sum of three consecutive integers is 71 less than the least of the integers. Find the integers.
storchak [24]

Answer:

-37, -36, -35

Step-by-step explanation:

x+x+1+x+2=x-71

3x+3=x-71

2x=-74

x=-37

So x=-37, x+1=-36, x+2=-35

Add these three numbers and you get -108 which is 71 less than -37

A carousel has 30 cars. Determine the angle of rotation that maps #6 to car #19.
ivolga24 [154]

Answer:  The answer is 260°.


Step-by-step explanation: Given that a Carousel has 30 cars. We need to find the angle of rotation which maps car no. 6 to car no. 19.

Now, the Carousel will make a regular polygon with 30 sides and each car as a vertex.

So, angle of symmetry for the polygon is

\theta=\dfrac{360^\circ}{30}=20^\circ.

Number of sides from car 6 to car 19 = 19 - 6 = 13.

Therefore, the angle of rotation that maps car 6 to car 19 is given by

\alpha=13\times \theta=13\times 20^\circ=260^\circ.

Thus, the required angle of rotation is 260^\circ.
