Answer:

The average approximate distance from the Earth to Venus is 4 x 10^7 km, which is 4 x 10^7 - 4 x 10^5 = <<410^7-410^5=4*10^5>>4 x 10^5 km farther than the distance of the moon from Earth. Answer: 4 x 10^5

The answer is (C) 126.

The sum of a geometric series can be found using the formula: S = a * (1 - r^n) / (1 - r), where a is the first term, r is the common ratio, and n is the number of terms.

In this case, the first term (a) is 2, the common ratio (r) is 2 (since each term is double the previous term), and the number of terms (n) can be found by noticing that 64 is equal to 2^6.

Substituting these values into the formula, we get: S = 2 * (1 - 2^6) / (1 - 2)

Simplifying further, we have: S = 2 * (1 - 64) / (-1)

S = 2 * (-63) / (-1)

S = 126

Therefore, the sum of the geometric series 2+4+8+...+64 is 126.

#SPJ11

The sum of the geometric series 2 + 4 + 8 + ... + 64 is 126. Hence, the answer is (C) 126.

The provided series is a geometric series with a common ratio of 2.

To determine the sum of the series, we can use the formula for the sum of a geometric series:

\(\[S = \frac{a \cdot (1 - r^n)}{1 - r}\]\)

where:

S is the sum of the series,

a is the first term of the series,

r is the common ratio,

and n is the number of terms.

In this case, the first term (a) is 2, the common ratio (r) is 2, and the number of terms (n) can be determined by finding the exponent that makes 64 the last term. Since 2 raised to the power of 6 (2⁶) equals 64, there are 6 terms in the series.

Using the formula, we can calculate the sum of the series:

\(\[S = \frac{{2 \cdot (1 - 2^6)}}{{1 - 2}}\)

\(= \frac{{2 \cdot (1 - 64)}}{{1 - 2}}\)

\(= \frac{{2 \cdot (-63)}}{{-1}}\)

= 2 * 63

= 126

Therefore, the correct answer is (C) 126.

Answer:

17.50

Step-by-step explanation:

1: 3.50 dollars

multiply by 5 on eahc side

5 : 17.50

The complete table to make a proportional relationship between weight and price is 17.50.

You start with an equation: 1 * 3.50 dollars

You want to multiply both sides of the equation by 5.

So, you have:

1 * 3.50 dollars = 5 * 3.50 dollars

On the left side, when you multiply 1 by 3.50 dollars, you get 3.50 dollars.

On the right side, when you multiply 5 by 3.50 dollars, you get 17.50 dollars.

So, the result of multiplying both sides by 5 is:

3.50 dollars = 17.50 dollars

This shows that if you have 1 item costing 3.50 dollars and you want to buy 5 of those items, the total cost would be 17.50 dollars.

After three iterations using the Gauss-Seidel method, the approximate values for x, y, and z are x ≈ 0.799, y ≈ 0.445, and z ≈ -0.445.

To solve the system of equations using the Gauss-Seidel method with three iterations, we start with initial values x = 0.8, y = 0.4, and z = -0.45. The system of equations is:

6x + y + z = 6

x + 8y + 2z = 4

3x + 2y + 10z = -1

Iteration 1:

Using the initial values, we can solve the first equation for x:

x = (6 - y - z) / 6

Substituting this value of x into the second equation, we get:

(6 - y - z) / 6 + 8y + 2z = 4

Simplifying:

6 - y - z + 48y + 12z = 24

47y + 11z = 18

Similarly, substituting the initial values into the third equation, we have:

3(0.8) + 2(0.4) + 10(-0.45) = -1

2.4 + 0.8 - 4.5 = -1

-1.3 = -1

Iteration 2:

Using the updated values, we can solve the first equation for x:

x = (6 - y - z) / 6

Substituting this value of x into the second equation, we get:

(6 - y - z) / 6 + 8y + 2z = 4

Simplifying:

6 - y - z + 48y + 12z = 24

47y + 11z = 18

Substituting the updated values into the third equation, we have:

3(0.795) + 2(0.445) + 10(-0.445) = -1

2.385 + 0.89 - 4.45 = -1

-1.175 = -1

Iteration 3:

Using the updated values, we can solve the first equation for x:

x = (6 - y - z) / 6

Substituting this value of x into the second equation, we get:

(6 - y - z) / 6 + 8y + 2z = 4

Simplifying:

6 - y - z + 48y + 12z = 24

47y + 11z = 18

Substituting the updated values into the third equation, we have:

3(0.799) + 2(0.445) + 10(-0.445) = -1

2.397 + 0.89 - 4.45 = -1

-1.163 = -1

After three iterations, the values for x, y, and z are approximately x = 0.799, y = 0.445, and z = -0.445.

Yvonne stops for water after 6/8 on the race for one more time.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Yvonne ran 3/8 of the race stopping for water.

This means,

After every 3/8 Yvonne stopped for water.

Now,

Total distance = 1

Distance remaining after one stop.

= 1 - 3/8

= 5/8

And,

Another stop will be after 3/8.

This means,

Distance remains after the second stop.

= 5/8 - 3/8

= 2/8

Now,

1 - 2/8

= 6/8

The second stop is after 6/8 of the race.

Thus,

Yvonne stops for water after 6/8 on the race for one more time.

Answer:

\(y=-\frac{1}{4} x-6\)

Step-by-step explanation:

The slope-intercept form is \(y=mx+c\), where m is the slope of the line and c is where the line crosses the \(y\)-axis.

To calculate \(m\) we can use the formula \(m = \frac{dy}{dx}\) where \(dy\) is the difference in \(y\) between two points and \(dx\) is the difference between \(x\).

Information we can get from the graph given: \(c=-6\). Since \(c\) is the point at which the line crosses the \(y\)-axis.

To find \(m\) let's get two points from the graph.

Point 1: \((4,-7)\)

Point 2: \((8,-8)\)

Now use the equation \(m = \frac{dy}{dx}\).

\(m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}\).

Now we have \(m\) and \(c\), let's put them back into the general equation.

Using systems of equations will help you find a better deal on renting a car.

Let's use these two equations as an example.

Company A. y=50x+120 where 120 is how much it costs to rent the vehicle and 50 is the rate per day. If you use company A, you will pay $50+$120= $170 for the first day, $220 for two days, etc...

Company B. y=40x+150 where 150 is how much it costs to rent the vehicle and 40 is the rate per day. If you use company B, you will pay $40+$150= $190 for the first day, $230 for two days, etc...

Now you have to take this into consideration - how long you're renting the vehicle for.

As you can see, at first Company A seems to have the better deal because of its low cost to rent a car, but it has a higher fee per day. Company B had a higher cost to rent a car initially, but the driver will pay a lower fee a day. Using Company A is beneficial for those who desire to rent a car for less than three days and Company B would be cheaper for those renting more than three days.

By using system of equation, you can determine the better deal according to the length of rental by comparing the initial cost and daily rental fee.

In order to calculate the z-scores for the given Confidence Interval (CI) levels, we need to use the Z-table. It is also known as the standard normal distribution table. Here are the z-scores for the given Confidence Interval levels:1. 68% CI: The confidence interval corresponds to 1 standard deviation on each side of the mean.

Thus, the z-score for the 68% \(CI is ±1.00.2. 85% CI\): The confidence interval corresponds to 1.44 standard deviations on each side of the mean.

We can calculate the z-score using the following formula:\(z = invNorm((1 + 0.85)/2)z = invNorm(0.925)z ≈ ±1.44\)Note that invNorm is the inverse normal cumulative distribution function (CDF) which tells us the z-score given a certain area under the curve.3. 99% CI: The confidence interval corresponds to 2.58 standard deviations on each side of the mean. We can calculate the z-score using the following formula:\(z = invNorm((1 + 0.99)/2)z = invNorm(0.995)z ≈ ±2.58\)

Note that in general, to calculate the z-score for a CI level of (100 - α)% where α is the level of significance, we can use the following formula:\(z = invNorm((1 + α/100)/2)\) Hope this helps!
