Answer:

Step-by-step explanation:

The first thing that is important to note is that every circle's arcs equal 360. So, you find arc QS by using the equation 120+140+x=360. Once you solve this you get 100. Next, it is important to understand what type of angle R is. The angle is on the circle; this means that the corresponding arc will be double the measurement of the angle. Therefore, divide 100 by 2 and you will have the final answer of 50.

marin [14]

Answer:

Step-by-step explanation:

From the table attached,

x-intercept of the linear function is, the value of 'x' when f(x) = 0

x = 3 [x-intercept]

Function 'g' is the sum of 2 and the cube root of the sum of three time x and 1.

g(x) = $2+\sqrt[3]{3x+1}$

For x-intercept,

g(x) = 0

$2+\sqrt[3]{3x+1}=0$

3x + 1 = (-2)³

3x + 1 = -8

3x = -8 - 1

3x = -9

x = -3

Therefore, the x-intercept of function 'f' is different or greater than the x-intercept of function g.
