Using the properties of logarithm the value of the expression is   [tex]log_{2}4 - log_{2}16 = -2[/tex]

We have been given two logarithm terms that is the first term is  [tex]log_{2}4[/tex] and second term is [tex]log_{2}16[/tex].

The propertied of logarithm that we are going to use are

          [tex]log a^{m} = m * log a[/tex]     and   [tex]log_{a} a = 1[/tex]

First we will find the value of the two terms and operate the above mentioned properties of logarithm to obtained the values of the logarithm.

Thus,

                [tex]log_{2}4 = log_{2}2^{2} \\ = 2* log_{2}2\\ = 2*1\\ = 2[/tex]         

Similarly,

Inverse of the given function F(x) = 3 x³- 4 is F⁻¹(x) = ∛[ ( y + 4 ) / 3 ]

Given is a function of x, F(x) = 3 x³- 4

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = 3 x³- 4 becomes y =  3 x³- 4

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = 3 x³- 4, we get

x =  3 y³- 4

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x =  3 y³- 4

=> x + 4 = 3 y³

=> 3 y³ = x + 4

=> y³ = ( x + 4 ) / 3

=> y = ∛( x + 4 ) / 3

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y = ∛( x + 4 ) / 3 becomes F⁻¹(x) = ∛( x + 4 ) / 3

Therefore, we get the inverse of the given function F(x) = 3 x³- 4 as F⁻¹(x) = ∛( x + 4 ) / 3

y = the total amount that he earned and x = the number of hours that he worked.

Step-by-step explanation:

The given quotient ( ∛8 x⁶ y¹² ) / ( √4 x⁴ y⁸ ) is x² y⁴.

This question can be easily solved by using the concept of roots. The two root terms mentioned in the question are ∛8 ( cubic root of 8 ) and  √4 (square root of 4 ). This question can be solved in 4 easy steps

Determining the power of the root and find the LCM of those numbers..

In this case, the powers of root for ∛8 and √4 are 3 and 2, respectively. Take LCM of 3 and 2.

LCM = 3 x 2 = 6

=> We get the LCM of 3 and 2 as 6.

Writing the given numbers as fractional powers.

∛8 = 8¹ˡ³  => The power of 8 = 1/3

√4 = 4¹ˡ²  => The power of 4 = 1/2

Step 3 : Multiply and divide the powers of the base number ( in this case 8 and 4 ) with a number such that you get the denominator as the LCM's ( in this case 6 )

1/3  can be multiplied and divided by 2 to get the denominator as 6

=> 1 * 2 / 3 * 2 = 2/6

1/2  can be multiplied and divided by 3 to get the denominator as 6

=> 1 * 3 / 2 * 3 = 3/6

Step 4 : Divide the two terms

6√8² x 6√4³ = 6√( 4 x 2 x 4 x 2 / 4 x 4 ) = 6√1 = 1

Also,  x⁶ y¹² / x⁴ y⁸ = x² y⁴

Answer:The probability would be 5 out of 12.

Rick paddles in still water at a rate of 6.5 mph. The rate of the current is 1.5 mph.

The rate at which an object moves from one point to another is also called speed. It can be measured by dividing the distance over time.

rate = distance/time

Let x = rate at which Rick paddles

c = rate of the current

If Rick paddles a kayak 20 miles upstream in 4 hours, and going upstream means the current is against your direction, then the equation for the travel is:

x - c = 20 miles/4 hours

x - c = 5     (equation 1)

If the return trip downstream takes him 2.5 hours, and downstream means that the current is going the same direction as you are, then the equation for the downstream travel is:

x + c = 20 miles/2.5 hours

x + c = 8     (equation 2)

Using elimination method, solve the two equations.

x + c = 8

x - c = 5

2x     = 13

x = 6.5

rate at which Rick paddles = 6.5 mph

Substitute x in equation 1 and solve for c.

x - c = 5     (equation 1)

6.5 - c = 5

c = 6.5 - 5

The probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.

Probability may be defined as the possibility of occurrence of an event. Probability of an event can be 0 or 1 but it can never be negative. If probability is 0 then the event will not occur and if probability is 1 then the event will definitely occur. Probability is given by the formula.

Probability = Favorable outcomes/Total number of outcomes.

Here, total number of outcomes = 20.

Now in the first case we need to find probability of picking a girl so favorable outcome is 2.

Probability of picking a girl = 2/20

Probability of picking a girl = 1/10

In the second case we need to find probability of picking a left-handed girl, so the favorable outcomes are 2 + 9 = 11 as total number of girls are 2 and total number of left-handed people are 9.

Probability of picking left-handed girl = 9 + 2/20

Probability of picking left-handed girl = 11/20

Thus, probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.
