In Expanded Form, Log(1,000a^3/b) Is Equivalent To...

Answers

Answer 1

Answer:

Option (4)

Step-by-step explanation:

Given expression is,

[tex]\text{log}(\frac{1000a^3}{b})[/tex]

To solve this expression we will use the logarithmic properties.

[tex]\text{log}(\frac{1000a^3}{b})=\text{log}1000a^3-\text{log}(b)[/tex] [Since, [tex]\text{log}\frac{p}{q}=\text{log}p-\text{log}q[/tex]]

                 = log(1000) + log(a³) - log(b) [Since, log(pq) = log(p) + log(q)]

                 = 3 + 3log(a) - log(b)

                 = 3[1 + log(a)] - log(b)

Therefore, Option (4) will be the correct option.

The length of a rectangular room is 8 feet more than twice the width. If takes perimeter of the room is 124 feet, what are its dimensions?

Answers

Hey there! I'm happy to help!

Let's call the length and width L and W respectively.

L=2W+8

2W+2L=124

We plug our value of L into the second equation and solve for W.

2W+2(2W+8)=124

We undo the parentheses with the distributive property.

2W+4W+16=124

Combine like terms.

6W+16=124

Subtract 16 from both sides.

6W=108

Divide both sides by 6.

W=18

We plug this W value into the first equation to solve for L.

L=2(18)+8

L=36+8

L=44

So, the length is 44 feet and the width is 18 feet.

Points P, Q, R, and S are collinear. Point Q is between P and R, R is between Q and S, and PQ =RS. If PS = 21 and PR = 16, what is the value of QR? QR = (Simplify your answer.)​

Answers

Greetings from Brasil...

→ Collinear points = points belonging to the same line

→ PQ is said to be equal to RS. Let’s call this distance X

→ let's call QR Y

With this information and the figure in the annex we can conclude that:

refer to attached

PQ = X

QR = Y

RS = PQ = X

then

PR = PQ + QR

16 = X + Y       i

PS = PR + RS

21 = 16 + X

X = 5       putting in i

16 = X + Y

16 = 5 + Y

Y = 11

So,

PQ = 5QR = 11RS = 5

Collinear points are points on the same line.

The value of QR is 11

From the question, we have:'

Q between P and RR between Q and S

This means that:

[tex]\mathbf{PR = PQ + QR}[/tex]

[tex]\mathbf{QS = QR + RS}[/tex]

[tex]\mathbf{PS = PR + RS}[/tex]

The given parameters are:

[tex]\mathbf{PS = 21}[/tex]

[tex]\mathbf{PR = 16}[/tex]

[tex]\mathbf{PQ = RS}[/tex]

Substitute the above values in [tex]\mathbf{PS = PR + RS}[/tex]

[tex]\mathbf{21= 16 + RS}[/tex]

Solve for RS

[tex]\mathbf{RS = 21- 16}[/tex]

[tex]\mathbf{RS = 5}[/tex]

This means that:

[tex]\mathbf{PQ = RS = 5}[/tex]

Substitute 5 for PQ in [tex]\mathbf{PR = PQ + QR}[/tex]

[tex]\mathbf{PR = 5+ QR}[/tex]

Substitute [tex]\mathbf{PR = 16}[/tex] in [tex]\mathbf{PR = 5+ QR}[/tex]

[tex]\mathbf{16 = 5+ QR}[/tex]

Solve for QR

[tex]\mathbf{QR = 16 - 5 }[/tex]

(a) Olivia deposits $8600 in a bank. The interest rate is 2.6% per annum.
Find the total interest she will earn in 4 years.

Answers

Answer:

Below in bold.

Step-by-step explanation:

You do not say if the interest is simple or compound.

Simple Interest: I = PRT/100

= (8600* 2.6 * 4)/ 100

= $894.40.

Compound Interest:- amount after 4 years

= 8600(1 + 0.026)^4

= $9529.89

So the compound interest

= 9529.89 - 8600

= $929.89.

Julie and her family go to the movies. They buy 2 adult tickets and 3 child tickets. An adult ticket costs $3.50 more than a child ticket. Julie's family spends $35.75. What is the cost of the adult ticket?
HELP PLS

Answers

Answer:

$9.25

Step-by-step explanation:

let x = the cost of a child ticket

3(x)+2(x+3.50)=35.75

3x+2x+7=35.75

5x=28.75

x=5.75 cost of child ticket

5.75+3.50= 9.25

Answer:

$9.25

Step-by-step explanation:

Start by multiplying 2 by 3.5. This will give you 7. Then subtract 7 from 35.75, which gives you 28.75. This is the full amount for five child tickets. Then you want to divide 28.75 by 5, giving you 5.75. This is the amount for a single child ticket, and because we know that an adult ticket is 3.50 more than a child ticket, you add 3.50 and 5.75, which gives you your final answer of 9.25.

what will be number of zeros in the square of the number 100? pls answer fasttttttttttt

Answers

Answer:

4

Step-by-step explanation:

The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000

Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.

So, the number 10,000 which is the square of 100 has 4 zeros.

A surf instructor has an initial fee of $12 and charges $8 per hour for lessons,

Please help me, i'm stupid and i don't know where, or how to find this.

Answers

Answer:

I am stuck on that question tooo

Step-by-step explanation:

Step-by-step explanation:

First, let's write an equation.

h= numbers of hours, the instructor will charge $8 per hour.

s= amount of $

"12" is the initial fee.

From this information the equation will look like:

s=8h

However, on our graph, we will have to start on 12 since this was the initial fee. (so on the y, put a dot on 12.)

I think that (0, 12) is the y-intercept but I'm not entirely sure. In reality, your graph can't have any negative h(x) or y(s) values so the graph would be shaped like an "L".

an angle of 60° in 17.3 s. The linear velocity
of the pendulum is 1.32 ft/s. Determine the
length of the pendulum.

Answers

Answer:

  21.81 ft

Step-by-step explanation:

For an arc of measure α and radius r, the arc length is ...

  s = r·α . . . . . . where α is in radians

Then the linear speed is ...

  s' = r·α'

Here the rate of change of arc angle is (π/3)/(17.3) rad/s, so the radius can be found to be ...

  r = s'/α/ = (1.32 ft/s)/((π/3)/17.3 rad/s) = 1.32·3·17.3/π ft

  r ≈ 21.81 ft

The length of the pendulum is about 21.81 feet.
