Answer:

7^3 = 343

7^4 = 2401

So log base 7 of 505 lies between 3 and 4.

The equivalent equations of \(2x+ 4y = 14\) and \(4x + y = 20\)

are \(2x+ 4y = 14\) and\(-16x -4y = -80\)

The system of equations is given as:

\(2x+ 4y = 14\)

\(4x + y = 20\)

Multiply both sides of the equations by -4.

So, we have:

\(-4 \times (4x + y) = -4 \times 20\)

Distribute the expression

\(-4 \times 4x -4 \times y = -4 \times 20\)

Evaluate all products

\(-16x -4y = -80\)

So, we have the following system of equations

\(2x+ 4y = 14\)

\(-16x -4y = -80\)

Hence, the equivalent equations are \(2x+ 4y = 14\) and\(-16x -4y = -80\)

The area enclosed by the ellipse is 20π square units.

The parametric equations of the ellipse are given as z = 5 cos(θ) and y = 4 sin(θ), where θ represents the angle parameter in the range 0 ≤ θ < 2π. To find the area enclosed by the ellipse, we need to integrate over the parameter θ. The area of an infinitesimally small element of the ellipse is given by dA = z dy, which can be calculated using the parametric equations. Integrating this expression from 0 to 2π will yield the total area enclosed by the ellipse.

Parametric equations allow us to express the coordinates of points on a curve in terms of one or more parameters. By using these equations, we can determine various properties of curves, including the area they enclose. In this case, the parametric equations for the ellipse are z = 5 cos(θ) and y = 4 sin(θ). These equations represent the height and width of the ellipse at each point along the curve. By integrating the product of these values, we can find the area enclosed by the ellipse. The integral limits, 0 to 2π, ensure that we consider the entire curve.

Step-by-step explanation:

Solving inequalities with addition is similar to solving equations with addition in the initial steps, but it differs in the final answer due to the inequality sign. In both cases, you use addition to isolate the variable. However, with inequalities, you must consider the direction of the sign throughout the process.

When solving inequalities with addition, like equations, the goal is to isolate the variable on one side. You use addition to simplify the expression. Begin by treating the inequality like an equation, adding or subtracting the same value to both sides to eliminate constants and isolate the variable.

For example, if you have \(\(2x + 5 > 10\)\), subtract 5 from both sides to get \(\(2x > 5\)\).

Here's where it diverges: since inequalities involve the relationship between two quantities, you need to be mindful of the inequality sign. When you multiply or divide both sides by a negative number, the inequality direction flips.

For example, if you multiply \(\(x < 3\)\) by -2, the sign changes to \(\(x > -6\)\).

Remember, you're looking for a range of values that satisfy the inequality. So, when representing your final answer, use the appropriate inequality sign. For instance, if \(\(3x + 2 \leq 8\)\), after simplifying, you'll have \(\(x \leq 2\)\), indicating that any value of \(\(x\)\) less than or equal to 2 satisfies the inequality.

In summary, while solving inequalities with addition is akin to solving equations with addition in the initial steps, the crucial distinction lies in managing the inequality sign throughout the process and representing the solution as a range of values that satisfy the inequality.

The sum $a b c$ is 11760 if the ratio of the areas of two squares is  \($\frac{32}{63}$\).

Let the side length of the first square be x and the side length of the second square be y. Then we have:

\(\frac{Area of first square}{Area of second square} = \frac{x^2}{y^2} = \frac{32}{63}\)

By cross multiplying, we get:

63 x² = 32 y²

And then by rearranging:

\(\frac{x}{y} = \frac{4\sqrt{7} }{9}\)

Now, rationalizing the denominator, we get:

\(\frac{x}{y} = \frac{4\sqrt{7} }{9} . \frac{\sqrt{7} }{\sqrt{7} } = \frac{28\sqrt{7} }{63}\)

Thus, a.b.c = 28.7.63 = 11760.

Therefore, the value of the sum $a b c$ is 11760.

Answer:

His speed is 66.25 miles/hour

Step-by-step explanation:

The rule of the constant speed is:

Speed = Distance ÷ Time

∵ Karim starts his journey at 11:00 a.m. and finishes at 3:00 p.m.

→ Count the hours from 11: 00 a.m. to 3:00 p.m.

∴ He takes 4 hours ⇒ (3 + 12 - 11)

∴ T = 4 hours

∵ The mileage reader is 66,750 miles at 11:00 a.m.

∵ The mileage reader is 67,015 miles at 3:00 p.m.

→ The distance that Karim is driving = the difference between them

∴ The distance that karim is driving = 67,015 - 66,750

∴ D = 265 miles

→ Substitute the values of D and T in the rule above

∵ S = 265 ÷ 4

∴ S = 66.25 miles/hour

∴ His speed is 66.25 miles/hour

When we roll three fair coins, there are two possible outcomes for each coin - either it lands heads up or tails up. There are 8 elementary events in the sample space of the experiment of rolling three fair coins.

The sample space of this experiment consists of all possible combinations of three outcomes, which can be calculated by multiplying the number of outcomes for each coin: 2 x 2 x 2 = 8.
Each of these combinations is called an elementary event, which means that there are 8 elementary events in the sample space of the experiment of rolling three fair coins. We can list them as follows:
1. HHH (all three coins land heads up)
2. HHT (two coins land heads up, one lands tails up)
3. HTH (two coins land heads up, one lands tails up)
4. THH (two coins land heads up, one lands tails up)

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The graph is forming a function but it is not an one-one function.

If the vertical line test is satisfied, then the graph represents a function and a vertical line will cross it at most once.

If a horizontal line crosses the graph in no more than one spot, the function is one-to-one and passes the horizontal line test.

The graph in this case is made up of several horizontal, non-overlapping lines. It is a function and passes the vertical line test, however a horizontal line can cross the graph at any number of locations (is not one-to-one).

Step-by-step explanation:

Total distance traveled during these 6 seconds = 80 feets

Given the data in the question-

Time (sec)        Velocity (ft/sec)

0                       13

1                        23

3                       24

4                       15  

5                        4

6                       10                          

Since the distance traveled is shown by.

Distance = Velocity x Time

And since the time interval in the question is given = 1 sec between any two breaks,

By the principle of left-end approximation -

According to the left-end approximation, the velocity given at each equal interval is determined by the function value at the left of each subinterval.

(0,1) ---------------- f (0) = 13

(1,2) ---------------- f (1) = 23

(2,3) --------------- f (2) = 24

(3,4) --------------- f (3) = 15

(4,5) --------------- f (4) = 4

(5,6) --------------- f (5) = 1

Now if we observe the time break between two-time intervals = 1 sec

The expression will be derived as -

= (13 x 1) + (23 x 1) + (24 x 1) + (15 x 1) + (4 x 1) + (1 x 1)

= 13 + 23 + 24 + 15 + 4 + 1

= 80 feets

Therefore, the total distance traveled during these 6 seconds = 80 feets

Holt linear exponential smoothing or  Holt-Winters exponential smoothing technique is best for data with a trend but no seasonality.

For trend but nonseasonal data, Holt linear exponential smoothing (aka double exponential smoothing) or Holt-Winters exponential smoothing (aka triple exponential smoothing) can be used to compare single exponential smoothing or Exponential smoothing is better than post-winter smoothing.

Holt's linear exponential smoothing method uses his two smoothing factors:

One for the level of the series and one for the trend. Suitable when data show a linear trend.

Holt-Winter exponential smoothing adds his third seasonal smoothing factor to Holt's linear exponential smoothing method. Appropriate when the data show trends over time and exhibit seasonal patterns. Therefore, Holt's linear exponential smoothing method is best when the data show a linear trend. Holt-Winters exponential smoothing is more appropriate when trends are more complex and there is evidence of seasonality.

Based on the information provided, 2 is not a solution of x>5 because a possible solution requires a number greater than 5.

Inequalities include symbols such as >, ≤, ≥, among others that should be interpreted correctly to solve the inequality. In this case, the symbol in the inequality is >, which means greater than. Based on this, the value of x should be greater than 5, for example, 7, 19, 2948, etc.

Therefore, 2 is not a solution to the inequality x>5 because a number greater than 5 rather than less than 5 is required to solve this expression.

Fractions are very important in many areas such as math, physics, engineering, chemistry and many more, understanding how to add fractions with unlike denominators is a fundamental skill that will help you in many aspects of your life.

Adding fractions with unlike denominators can be a bit tricky, but with the right understanding and techniques, it's definitely doable.

When we add fractions with unlike denominators, we need to first find a common denominator. A common denominator is a number that is a multiple of both denominators. Once we have a common denominator, we can add the fractions as usual by adding the numerators and keeping the denominator the same.

Here are a few examples of adding fractions with unlike denominators:

2/3 + 1/4

We can find a common denominator by finding the least common multiple (LCM) of 3 and 4. The LCM of 3 and 4 is 12.

So, we can convert 2/3 to 8/12 by multiplying the numerator and denominator by 4.

We can convert 1/4 to 3/12 by multiplying the numerator and denominator by 3.

Now we can add the fractions by adding the numerators: 8/12 + 3/12 =

1/5 + 2/7

We can find a common denominator by finding the least common multiple (LCM) of 5 and 7. The LCM of 5 and 7 is 35.

So, we can convert 1/5 to 7/35 by multiplying the numerator and denominator by 7.

We can convert 2/7 to 10/35 by multiplying the numerator and denominator by 5.

So, we can convert 3/4 to 9/12 by multiplying the numerator and denominator by 3.

We can convert 1/3 to 4/12 by multiplying the numerator and denominator by 4.

Now we can add the fractions by adding the numerators: 9/12 + 4/12 = 13/12

So, 3/4 + 1/3 = 13/12

It's important to note that when adding fractions, it's also important to simplify the final result if possible.

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of a right triangle is called the hypotenuse and the other two sides are the legs.

The tangent ratio relates the opposite leg with the adjacent leg. Please note the given side is the opposite leg to 60° and x is the adjacent leg to 60°, thus we apply the tangent ratio:

\(\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}\)

\(\displaystyle \tan 60^\circ=\frac{3\sqrt{3}}{x}\)

Solving for x:

\(\displaystyle x=\frac{3\sqrt{3}}{\tan 60^\circ}\)

Since:

\(\tan 60^\circ=\sqrt{3}:\)

\(\displaystyle x=\frac{3\sqrt{3}}{\sqrt{3}}\)

Answer:

1 bedroom = $280

2 bedroom = $400

3 bedroom = $560

Step-by-step explanation:

Given that :

Total rent received = 1240

Rent amount of 3 bedroom = 2 times rent of 1 bedroom

Let 1 bedroom = x

2 bedroom = y

3 bedroom = 2x

x + y + 2x = 1240

3x + y = 1240 ---(1)

Repair cost :

10% of x = 0.1x

20% of y = 0.2y

30% of 2x = 0.6x

0.1x + 0.2y + 0.6x = 276

0.7x + 0.2y = 276 - - - (2)

From (1)

y = 1240 - 3x

0.7x + 0.2(1240 - 3x) = 276

0.7x + 248 - 0.6x = 276

0.1x + 248 = 276

0.1x = 28

x = $280

1 bedroom = $280

3 bedroom = $280 * 2 = $560

2 bedroom = $1240 - $840 = $400
