Answer: x = 1/16

Step-by-step explanation:

Since the inverse of a Logarithm is an exponential function, we know that the final solution has to involve an exponential function somewhere in it.

1. log B(2) {x} = -4  || given

2. x = 2 ^ -4  || Logarithm rule that allows you to move the base of the logarithm to the base of the exponent on the other side. For example, if you had log B(5) {x} = 3, the base of 5 would move over to the other side and it would be raised to 3; x = 5^3.

3. x = (1) / (2^4) || Simplify. Use the negative exponent rule. This rule always leaves a numerator of 1, and a denominator of your exponent. In this case, it will be 2 ^ -4, so you will do 2^4 which is 16 and you will put that over 1. Resulting in your final answer of x = 1/16

Determine the solution set of (2x - 5)2 = 11.
zhenek [66]
I think what you meant was

(2x - 5)² = 11 -- (1)

Square root both sides of (1), i.e.

√(2x - 5)² = ± √11 -- (2)

From (2), we have

2x - 5 = ± √11 -- (3)

By adding 5 to both sides in (3), we have

2x = 5 ± √11 -- (4)

Divide both sides of (4) by 2, and we obtain

x = (5 ± √11)/2 -- (5)

From (5), the solution set of (1) is

x = (5 + √11)/2, (5 - √11)/2 ...Ans.

You need to buy 8 packages of meat for a cookout. A package of hot dogs costs $2.19 and a package of hamburgers costs $5.89. You
Daniel [21]

Answer:

1.89x + 5.19y = 31.62.

Step-by-step explanation:

Let the pagke of hot dags be x

Let the pakage of hamburgers be y

Now they total up tp 8 packages.

xEliminate the cost

x+y=8

y=8-x

Cost of hotdogs = $1.89

Cost of hamburgers = $5.19

1.89x+5.19y=31.62

1.89x+5.19(8-x)=31.62

1.89x+41.52-5.19=31.62

-3.3x=--9.9

x=3

y=8-3

y=5

Let x be the amount of time (in minutes) that a particular San Francisco commuter must wait for a BART train. Suppose that the d
babymother [125]

Answer:

a) P (x is less than 11 minutes) =  0.55

P (x is more than 14 minutes) = 0.3

b) P (x is between 8 and 13 minutes) = 0.25

c)  P(x < c) =0.8 is 0.05 x c = 0.8

Step-by-step explanation:

a) P (x is less than 11 minutes) = 11 x 0.05

                                                 = 0.55

P (x is more than 14 minutes) = 0.05 x (20 - 14)

                                                = 0.05 x 6

                                                = 0.3

b) P (x is between 8 and 13 minutes) = 0.05 x (13 -8)

                                                            = 0.05 x 5

                                                             = 0.25

c)  P(x < c) =0.8

The area between 0 and c is 0.8

Hence,

0.05 x c = 0.8
