Lina20 [59]3 years ago
4 0

Answer:

radius = circumference / (2 * PI)

radius = 5.8378033126

Circle Area = PI * radius^2

Circle Area = PI * 5.8378033126^2

Circle Area = PI * 34.0799475167

Circle Area = 107.07 square units

Can someone help me how do you eliminate “x”
Contact [7]

Answer:

Multiply the bottom one by -4

Step-by-step explanation:

to cancel in a system of equations, there must be a negative and a positive of both variables. - times - equals +, so multiply -x by -4 to get 4x, thus cancelling -4x with 4x.

Choose the graph which matches the function. (2 points) <br> f(x) = 3x-1
ValentinkaMS [17]

Answer:

Observe the attached image

Step-by-step explanation:

We know that f(x) = 3^{x-1} is an exponential function, therefore its graph must have the form that corresponds to this type of functions.

The first thing to do is find the cut points of the function.

Cut point with the y axis:

x = 0\\\\y = 3^{0-1}\\\\y = 3^{-1}\\\\y = \frac{1}{3}

The function cuts the y-axis on y = \frac{1}{3}

Cutting point with the x axis:

y = 0\\\\0 = 3^{x-1}

To clear x we must apply log on both sides of the equality, but the log(0) is not defined. Then, the function does not cut to the x axis.


The graph that represents the function f(x) is the one that cuts in y = \frac{1}{3} and does not cut the x-axis
