If f(x)= x^1/2 - x and g(x)= 2x^3 - x^1/2 - x, find f(x) - g(x)
Pavlova-9 [17]

Answer:

-2x^3+2x^{1/2}

Step-by-step explanation:

First, you have to substitute both functions into the equation to get:

f(x)-g(x) = (x^{1/2}-x) - (2x^3-x^{1/2}-x)

Then, you distribute the negative sign in front of g(x) to get:

= x^{1/2} - x -2x^3+x^{1/2}+x

And finally, you add/subtract the x's that have the same power to get:

=-2x^3+2x^{1/2}

Howard chose a candy from a bowl with 5 chocolate candies, 4 gummy candies and 6 hard candies. What is Howard's dependent probab
Hatshy [7]

Answer:

8.9%

Step-by-step explanation:

Here, we are to calculate the probability of Howard choosing a chocolate candy followed by a gummy candy.

The probability of selecting a chocolate candy = number if chocolate candy/ total number of candy

Total number of candy = 5 + 4 + 6 = 15

Number of chocolate candy = 5

The probability of selecting a chocolate candy = 5/15 = 1/3

The probability of selecting a gummy candy = number of gummy candies/total number of candies

Number of gummy candy = 4

The probability of selecting a gummy candy = 4/15

The probability of selecting a chocolate candy before a gummy candy = 1/3 * 4/15 = 4/45 = 0.088888888889

Which is same as 8.89 percent which is 8.9% to the nearest tenth of a percent
