what is 3log(2)3-log(2)(x+4) written as a single logarithm

Check the picture below.

let's recall Cavalieri's principle, that solids with equal altitudes and identitical cross-sectional areas at each part all the way up, have the same volume.

so, for a prism like this that is not oblique, with rhombic bases of area 600 and a height/altitude of 24, the volume will simply be the base * height, 600 * 24 = 14400.

well, based on Cavalieri's principle, an oblique one will also have the same volume.

Answer:

The volume of the prism is 14400 units³.

Step-by-step explanation:

It is given that an oblique prism is created using rhombuses with edge lengths of 25 units.

The volume of a prism is

[tex]V=B\times h[/tex]                   ..... (1)

Where, B is base area and h is height of the prism.

It is given that the area of one rhombus is 600 sq units. The perpendicular distance between the bases is 24 units.

Substitute B=600 and h=24 in equation (1) to find the volume of the prism.

[tex]V=600\times 24[/tex]

[tex]V=14400[/tex]

Therefore the volume of the prism is 14400 units³.

Answer:

simple random

In a simple random sample, individuals all have an equal chance of being selected, ensuring unbiased and representative data. Thus, option a. is correct.

In a simple random sample, individuals all have an equal chance of being selected, and all samples have an equal chance of being selected. This method ensures that each member of the population is equally likely to be chosen, resulting in unbiased and representative data.

Other sampling methods like cluster sampling and stratified sampling do involve randomness but in different ways. For instance, cluster sampling involves selecting entire clusters, such as departments or geographical areas, at random and including all members from those clusters in the sample.

In contrast, stratified sampling involves dividing the population into strata based on characteristics and then randomly sampling from each stratum.

Thus, option a. simple random sample is correct.

Answer:

Square with side length 25/4 m

Step-by-step explanation:

The area is always going to be largest for a rectangle when the two dimensions are equal.  You are looking for a square. What square has perimeter 25? 4s=25 so the side length of this rectangle (Square) is 25/4 m.

Answer:

It's a square  6.25 * 6.25 m.

Step-by-step explanation:

We can do this using calculus.

Let the  length of the  rectangle be x m.

2x + 2w = 25   where w = the width.

2w = 25 - 2x

w = 12.5 - x

So the area A = x(12.5 - x) = 12.5x - x^2.

Finding the derivative:

dA /dx = 12.5 - 2x

For a maximum area this = zero

12.5 - 2x = 0

x = 6.25m.

and w = 25 - 12.5  = 6.25m.

(For any rectangle the  maximum area is always a square).

inal answer:

To calculate the reimbursement rate per gallon, multiply the total miles traveled by all employees by the average gas mileage and divide the total reimbursement amount by the total gallons used, resulting in a rate of $1.40 per gallon.

Explanation:

To find the rate in dollars per gallon that the company uses to reimburse employees, we need to calculate the total gallons of gas consumed and then divide the total amount paid out by the total gallons used.

The average employee traveled 12,250 miles, and the average gas mileage was 22.5 miles per gallon:

Total miles for all employees: 126 employees × 12,250 miles/employee = 1,543,500 miles.

Total gallons consumed: 1,543,500 miles ÷ 22.5 miles/gallon = 68,600 gallons.

Rate of reimbursement per gallon: $96,040.00 ÷ 68,600 gallons ≈ $1.40 per gallon.

Therefore, the reimbursement rate is $1.40 per gallon.

Final answer:

The reimbursement rate in dollars per gallon is calculated by determining the total gallons of gas used by all employees and then dividing the total reimbursement amount by this figure. The computation shows a reimbursement rate of $1.40 per gallon.

Explanation:

To determine the rate in dollars per gallon that the company uses to reimburse employees, we need to calculate the total gallons of gas used by the average employee and then find out how much the company paid per gallon.

Thus, the correct answer is C) $1.40 per gallon.

Step-by-step explanation:

If the triangle is translated ANY amount of units ANYWHERE, the length of each segment AND the angles will ALL be the same.

Why?

Because if you translate something, you are only moving it somewhere else. You aren't stretching the shape or making any modifications. You are simply moving it, and that will only change the coordinates the points will be at.

The length of A1B1 is 10.

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

0.89 = 1 - 1/(k²)

Start by subtracting 1 from both sides:

0.89 - 1 = -1/(k²)

-0.11 = -1/(k²)

Multiply both sides by -1:

0.11 = 1/(k²)

Multiply both sides by k²:

0.11 k² = 1

Divide both sides by 0.11:

k² = 1 / 0.11

Take the square root:

k = √(1 / 0.11)

Answer:

+/- 3.015 to the nearest thousandth.

Step-by-step explanation:

0.89 = 1 - 1 / k^2

Multiply through by k^2

0.89k^2 = k^2 - 1

k^2 - 0.89k^2 = 1

0.11 k^2 = 1

k^2 = 1/0.11 = 9.091

k = +/- √0.091

Answer:

5/9(F-32) = C

Step-by-step explanation:

F= 9/5C+32

Subtract 32 from each side

F-32= 9/5C+32-32

F-32 = 9/5 C

Multiply each side by 5/9 to isolate C

5/9(F-32) = 5/9*9/5 C

5/9(F-32) = C

Final answer:

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8) and then add 32. For example, to convert 20 degrees Celsius to Fahrenheit: (9/5) * 20 = 36, and then add 32 to get 68 degrees Fahrenheit.

Explanation:

To solve the formula for converting temperature from degrees Celsius (C) to degrees Fahrenheit (F), you start with the given equation:

F = [tex]\frac{9}{5}[/tex]+ 32

This equation allows you to convert a temperature from Celsius to Fahrenheit by multiplying the Celsius temperature by 9/5 (or 1.8) and then adding 32. The formula reflects the fact that the Fahrenheit scale has a freezing point at 32 degrees higher than the Celsius scale's freezing point, and that each degree Celsius is equivalent to 1.8 degrees Fahrenheit. Here's a step-by-step explanation to convert Celsius to Fahrenheit:

Multiply the Celsius temperature by 9/5.

Add 32 to the result of this multiplication to get the temperature in Fahrenheit.

For instance, to convert 20 degrees Celsius to Fahrenheit:

(9/5) * 20 = 36

36 + 32 = 68 degrees Fahrenheit.

Hence, 20 degrees Celsius is equal to 68 degrees Fahrenheit when you apply the temperature conversion formula.

Answer:

The mixed number, can be written as the improper fraction, . The reciprocal of is found by interchanging (“flipping”) the numerator and denominator. When you divide by a whole number, you multiply by the reciprocal of the divisor.

Step-by-step explanation:

To get the reciprocal of a fraction, swap the numerator and denominator; if the original fraction's numerator is divisible by the denominator, the reciprocal will be a whole number. Multiplying by a fraction is the same as dividing by its reciprocal.

To find the reciprocal of a fraction, you simply swap the numerator and the denominator.

For example, the reciprocal of ⅔ (which is 2/8) is 8/2.

However, if you have a fraction and you want to get a reciprocal that is a whole number, you must ensure that the numerator of the original fraction is divisible by the denominator.

If we consider the fraction ⅕ (which is 1/5), its reciprocal is 5/1, or simply 5, which is a whole number.

In essence, finding a reciprocal involves flipping the fraction: turning the top number (numerator) into the bottom number (denominator), and the bottom number into the top number.

This process is akin to multiplying or dividing by the fraction.

For instance, when you multiply a value by a fraction, you are effectively dividing by its reciprocal, and vice versa.

Multiplying fractions involves multiplying the numerators together and the denominators together, and simplifying where possible.

ANSWER

[tex]m \angle ACE = 80 \degree[/tex]

EXPLANATION

Recall that adjacent angles on a straight line will add up to 180°

From the diagram, m<ACD and m<ACE are adjacent angles on a straight line because they have a common vertex at C.

We sum the two angles and equate them to 180°

[tex] m \angle \: ACD + m \angle ACE = 180 \degree[/tex]

From the diagram

[tex]m\angle ACD= 100 \degree[/tex]

We substitute the known angle to obtain:

[tex]100 \degree + m \angle ACE = 180 \degree[/tex]

[tex]m \angle ACE = 180 \degree - 100 \degree[/tex]

[tex] \therefore \: m \angle ACE = 80 \degree[/tex]
