Answer:

0.046875 aka 3/64

Step-by-step explanation:

In a geometric sequence, each term will be related to the previous term by undergoing either multiplication or division.

In this case, each case is exactly 1/2 of the previous term. 12 is half of 24, and 6 is half of 12. By continuing this sequence, we get

1: 24

2: 12 (24 * 1/2)

3: 6 (12 * 1/2)

4: 3 (6 * 1/2)

5: 3/2 (3 * 1/2)

6: 3/4 (3/2 * 1/2)

7. 3/8 (3/4 * 1/2)

8. 3/16 (3/8 * 1/2)

9. 3/32 (3/16 * 1/2)

10. 3/64 (3/32 * 1/2)

Answer:

[tex]y = - \frac{4}{5} x + \frac{6}{5} [/tex]

Step-by-step explanation:

First subtract 4x on both sides in order to get -5y alone. Now you have -5y = 4x + 6 (since neither 6 nor 4x are like terms). Now divide -5 on both sides in order to get rid of it, so we can get y by its self. Now you have y = -4/5 x + 6/5

Hope this makes sense. Also please tell me if I'm wrong and I'll be happy to look at it again for ya :)

Answer:

log ( x^2/(yz^2))

Step-by-step explanation:

2 log x - log y - 2 log z

We know a log b = log b^a

Rewriting

2 log x = log x^2  and 2 log z = log z^2

log x^2 - log y -  log z^2

Rewriting

log x^2 - (log y +  log z^2)

We know that log a + log b = log (a*b)

log x^2 - (log (y z^2))

And we know log a - log b = log (a/b)

log ( x^2/(yz^2))

Answer:

[tex]log\frac{x^2}{yz^2}[/tex]

Step-by-step explanation:

Simplify 2log(x) by moving 2

inside the logarithm.

Simplify 2log(x) by moving 2

inside the logarithm.

log(x^2)−log(y)−2log(z)

Simplify −2log(z)

by moving 2

inside the logarithm.

log(x^2)−log(y)−log(z^2)

Use the quotient property of logarithms, logb (x)−logb (y)=logb (x/y)

[tex]log\frac{x^2}{y} - log(z^2)[/tex]

Use the quotient property of logarithms, logb(x)−logb(y)=logb (x/y)

[tex]log (\frac{x}{y})/( \frac{1}{z^2}}][/tex]

Multiply the numerator by the reciprocal of the denominator.

[tex]log\frac{x^2\\ }{y}.\frac{1}{z^2}[/tex]

Combine.

[tex]log\frac{x^2*1\\ }{yz^2}[/tex]

Multiply [tex]x^{2}[/tex] by 1

[tex]log\frac{x^2}{yz^2}[/tex]

[tex]y = x + \pi[/tex]

Step-by-step explanation:

We need to find the slope of the line tangent to y at [tex]x=-\pi[/tex] and we can do that by calculating the derivative of y at that point. We know that

[tex]y'(x) = \dfrac{d}{dx}(\tan{x}) = \sec^2{x}[/tex]

and

[tex]y'(-\pi) = \sec^2(-\pi) = 1[/tex]

To find the equation of the tangent line, we know that the line passes through the point [tex](-\pi, 0)[/tex] so we can write the slope-intercept form of the line's equation as

[tex]0 = (-\pi) + b \Rightarrow b = \pi[/tex]

Therefore, the equation of the line tangent to the point [tex]x = -\pi[/tex] is

[tex]y = x + \pi[/tex]

The graph of the two functions is shown above.

Step-by-step explanation:

The compound interest formula can help with that.

  A = P(1 +r/n)^(nt) . . . . value of principal P at rate r for t years, compounded n times per year.

  P = A(1 +r/n)^(-nt) = $8000(1 +0.04/2)^(-2·6) = $8000(1.02^-12) = $6307.95

Gone Fishing Four friends go fishing one day and bring home a total of 11 fish. If each person caught at least 1 fish, then C) One person caught fewer that 3 fish.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

It is given that Gone Fishing Four friends go fishing one day and bring home a total of 11 fish. If each person caught at least 1 fish, then we need to find the following must be true.

The 75 exhibits are in the reptile house.

we have given that,

A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house.

We have to determine how many exhibits are in the reptile house.

Therefore we have

if 15 exhibits = 20% of total exhibits,

A percentage is a number or ratio expressed as a fraction of 100.

then 15/20% = 75 total exhibits in the reptile house

We can check the answer,

75 x 20% = 15

Therefore the 75 exhibits are in the reptile house.

Answer:

one bus travels at 66mi/hr and the other bus at 49mi/hr

Step-by-step explanation:

Let's assume one bus, A is traveling at x mi/hr and the other bus, B at x+17 mi/hr

after 3hrs, bus A will have covered 3x miles and bus B will have covered 3(x+17) miles.

the buses are 345 mils apart but from the same origin,

meaning Distance of A + Distance of B =345 miles

3x+3(x+17)=345

x=49

for bus A

and x+17=66 for bus B

Answer:

Step-by-step explanation:

xy = 864

x + y = 60                     Solve for y in the second equation

y = 60 - x                      

x * (60 - x) = 864          Remove the brackets.

60x - x^2 = 864           Put in order of powers and subtract 864

-x^2 + 60x - 864 =0    Multiply through by -1

x^2 - 60x + 864 = 0

This factors

(x - 36)(x - 24) = 0

Either

x - 36 = 0    in which case

x = 36

or

x - 24 = 0

x = 24

The two numbers are x = 36 and y = 24

of x = 24 and y = 36

Answer:

2/3 probability

Step-by-step explanation:

less than 5 is 4. There are 6 sides, so its 4/6. 4 out of 6 simplifies to 2/3.

Answer:

as there are 2 six-sided dices so total cases = 6*6 = 36

products less than 5 are = (1,1) , (1, 2), (1, 3), (2,1), (2,2), (3,1)

so number of products less than 5 = 6

so the probability = 6/36 = 1/6

Answer:

[tex]p=(12.75+7.25)/8[/tex]

Step-by-step explanation:

The money she earned is the remaining money plus the board game price. With the total profit, you divide by the 8 puzzles

Brittany received an amount of $2.50 for each puzzle in her collection.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's assume the amount of money Brittany received for each puzzle in her collection is p dollars.

Then the total amount of money she received for 8 puzzles will be 8p dollars.

If she used $7.25 to buy a board game, then the amount of money she had before purchasing the board game was 12.75 + 7.25 = $20.

We know that the total amount of money Brittany received for 8 puzzles was 8p dollars. So we can write an equation:

8p = 20

Divide both sides by 8:

p = 2.5

Therefore, he received $2.50 for each puzzle in her collection.
