Remember that both the denominator and the square root function cannot have values less than 0. So to figure what values can go into each we need to do a little math. Set both the denominator and the under the radical equal to 0
x + 2 = 0 x - 3 = 0
x = -2 x = 3

Since they must be those numbers or bigger 3 is the larger of the 2 the final answer is
x >= 3 Type in greater than into the box

Can somebody please help me

Nataly [62]

Answer:

The probability of drawing the first pink ball is $\frac{3}{10}$ .

Because you drew that first pink ball, there are two pink balls left and the total number of balls left is nine.

Hence, the probability of drawing another pink ball after drawing the first pink ball would be:

$\frac{3}{10} *\frac{2}{9} =\frac{1}{15}$

Select the correct answer from each drop-down menu. The table below represents the function f, and the following graph represent

Lorico [155]

<h3>Answers:</h3>

The functions f and g have <u>same axis of symmetry</u>

The y intercept of f is <u>greater than</u> the y intercept of g.

Over the interval [-6,-3], the average rate of change of f is <u>less than</u> the average rate of change of g.

===========================================

Explanation:

Check out the diagram below.

Using the table, plot each (x,y) point onto the same xy grid the blue parabola is graphed on. This way we can compare the two graphs. I'll show these points in red. The red parabola passing through them represents all of f(x) assuming it is continuous.

When we have f(x) and g(x) plotted together, we see that they have the same axis of symmetry. Points D = (-3,-10) and K = (-3,7) have the same x coordinate. The axis of symmetry for each is x = -3.

-------------

Furthermore, the graph shows that the y intercept of f is above the y intercept of g. Look where the graphs cross the y axis. So The y intercept of f is greater than the y intercept of g

We could note that from the table, the y intercept of f is (0,8) as the y intercept always happens when x = 0.

-------------

Last part is the average rate of change (AROC)

AROC is the same as the slope of the line through the endpoints mentioned. The interval [-6, -3] means we go from x = -6 to x = -3. Those x values determine the endpoints.

For f(x), this means we find the slope of the line through (-6,8) and (-3,-10). Use the slope formula to get

m = (y2-y1)/(x2-x1)

m = (-10-8)/(-3-(-6))

m = (-10-8)/(-3+6)

m = -18/3

m = -6 ... negative slope goes downhill as we move from left to right

The AROC for f, on the mentioned interval, is -6

The AROC for g is done in a similar manner. We use the two points J = (-6,-2) and L = (-3,7) as the diagram shows. The slope of line JL is

m = (y2-y1)/(x2-x1)

m = (7-(-2))/(-3-(-6))

m = (7+2)/(-3+6)

m = 9/3

m = 3 ... positive slope goes uphill as we move from left to right

We get a different AROC here. More specifically, this is a larger AROC compared to what we got for f. So the AROC for f is smaller than the AROC for g.

13. Find the measure of ZABC. Show your work.<br>

ale4655 [162]

Answer:

47°

Step-by-step explanation:

In the picture attached, the problem is shown.

When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:

∠ABC = 1/2*(arc DE - arc AC)

Replacing with data from the picture:

∠ABC = 1/2*(142° - 48°)

∠ABC = 47°
