what is a skew line?

Answers

Answer 1

In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel.

Answer 2

Skew lines are non-coplanar lines that do not intersect. For example, take a look at the image provided below. Lines m and n in the diagram do not lie on the same plane and they don't intersect. Therefore, we can say that line m is skew to line n.

Although this problem can be solved easily if given the figure, we can simply imagine to solve this. We see that we are given two points of the quadrilateral which are (2, 4) and (2, 3). This means that from P to Q, there is only a distance of 1. Since a quadrilateral has 4 equal sides therefore the perimeter is 4 units.

In a recent year there were about 400,000,000 mobile internet users. That same year, there were about 1.2* into 10 ninths desktop internet users. About how many time larger was the number of desktop internet users than the number of mobile internet users?

Answers

Final answer:

The number of desktop internet users is 3 times larger than the number of mobile internet users.

Explanation:

To find out how many times larger the number of desktop internet users is compared to mobile internet users, we need to perform a division. We divide the number of desktop internet users by the number of mobile internet users.

The number of desktop internet users is represented as 1.2 x 109. To simplify this number, we can write it as 1,200,000,000. The number of mobile internet users is 400,000,000.

Now, we divide the number of desktop internet users by the number of mobile internet users:

1,200,000,000 / 400,000,000 = 3

Therefore, the number of desktop internet users is 3 times larger than the number of mobile internet users.

A bag has 4 red marbles, 5 white marbles, and 6 blue marbles. three marbles are drawn from the bag (without replacement). what is the probability that they are all the same color?

Answers

Final answer:

The probability that the three marbles drawn are all the same color is 64/3375.

Explanation:

To find the probability that all three marbles drawn are the same color, we need to consider two cases:

1. The probability of drawing three red marbles
2. The probability of drawing three white marbles

For the first case, the probability of drawing one red marble from the bag is 4/15. After replacing the marble, the probability of drawing another red marble is still 4/15. So, the probability of drawing three red marbles is (4/15) * (4/15) * (4/15).

For the second case, the probability of drawing one white marble from the bag is 5/15. After replacing the marble, the probability of drawing another white marble is still 5/15. So, the probability of drawing three white marbles is (5/15) * (5/15) * (5/15).

Adding the probabilities of the two cases, we get (4/15) * (4/15) * (4/15) + (5/15) * (5/15) * (5/15), which simplifies to 64/3375.

The probability of a 5-bit binary code word containing exactly one zero, when each bit has a 0.8 probability of being zero, is calculated using the binomial probability formula. The final answer to this problem is 0.0064.

Explanation:

The student is asking about the probability of having exactly one zero in a 5-bit binary code where each bit has a probability of 0.8 of being zero. To calculate this, we will consider the binomial distribution where the number of trials (n) is 5 (since the code has 5 bits) and the probability of success (having a zero) in each trial (p) is 0.8. We want to find the probability of having exactly one success (one zero).

Using the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k),

where X is the random variable representing the number of zeros, and k is the number of successes (zeros) we want, which in this case is 1. We plug in our values:

n = 5

k = 1

p = 0.8

P(X = 1) = (5 choose 1) * 0.8^1 * (1-0.8)^(5-1) = 5 * 0.8 * 0.2^4 = 0.0064.

The final answer is that the probability of a 5-bit binary code containing exactly one zero is 0.0064.

Mike and his friend were playing 2 on 2 at the public court. They were using a homemade basketball and the volume of the ball was 288p. A regulation basketball has a circumference between 29.5-30 in. Can this ball be used in a regulation basketball game?

Answers

Volume = (4/3) pi r^3

288 pi = (4/3)pi r^3

r^3 = 288 / (4/3) = 216

r = 6 ins.

Circumference of the ball = 2 pi r = 2*pi*6 = 37.70 in so this ball cannot be used in a regulation game of basketball.

The equation y = 1.55x + 110,419 approximates the total amount, in dollars, spent by a household to raise a child in the United States from birth to 17 years, given the household’s annual income, x. Assume the household’s total cost of raising a child is $197,219. What is the household’s annual income?

Answers

x=56,000 hope this help

Answer: $56,000

Step-by-step explanation:

Given: The equation [tex]y=1.55x+110,419[/tex] approximates the total amount, in dollars, spent by a household to raise a child in the United States from birth to 17 years, given the household’s annual income, x.

The household’s total cost of raising a child = $197,219

Put the above value in the equation, we get

[tex]197,219=1.55x+110,419\\\Rightarrow\ 1.55x=197219-110419\\\Rightarrow\ x=\frac{86800}{1.55}\\\Rightarrow\ x=56,000[/tex]

Hence, the household’s annual income is $56,000.

For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year. The value, V(t) of $408,000 worth of assets after t years, that depreciate at 18% per year, is given by the formula V(t) = Vo(b)t. What is the value of Vo and b, and when rounded to the nearest cent, what are the assets valued at after 8 years?

Answers

The formula V(t) = Vo(b)^t
Vo is the value of assets 408000
b=1-r
R rate of depreciation 0.18
b=1−0.18=0.82
T time ( number of years )
So after 8 years the value of the assets is
V (8)=408,000×(0.82)^(8)=83,400.94
Round your answer to get 83401

Hope it helps!

In the depreciation formula V(t) = Vo(b)^t, Vo is the initial value of $408,000, and b is 0.82 (1 minus 18% depreciation). After 8 years, using these values, the assets are valued at approximately $68,818.46 when rounded to the nearest cent.

The student's question relates to the depreciation of business assets over time. In the formula V(t) = Vo(b)^t, Vo represents the initial value of the assets and b represents the depreciation rate expressed as a base for the exponential function. Knowing that the asset is worth $408,000 initially and depreciates at 18% per annum, Vo equals $408,000, and b equals (1 - 0.18) or 0.82, which reflects the remaining value of the asset after one year.

To calculate the value after 8 years, we use the formula with the given values: V(8) = 408,000(0.82)^8. The calculation proceeds as follows:

V(8) = 408,000(0.82)^8V(8) = 408,000(0.1686747) (approximately after the 0.82 taken to the 8th power)V(8) = 68,818.46 (rounded to the nearest cent

To answer the question, the value of the assets after 8 years, rounded to the nearest cent, is $68,818.46.

Which statement is true about the domain of y = 3(2^-x)? Explain.

Answers

We want to determine the domain of [tex]{y=3 \cdot 2^{-x}=3 \cdot ({2^{-1}})^x=3 \cdot ({ \frac{1}{2}})^x[/tex]

any function of the form [tex]y=f(x)=a \cdot b^x[/tex] is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.

The domain of such functions is all real numbers.

That is for any x, the expression 3(2^-x) "makes sense".

Answer: The domain is all real numbers

The correct statement about the domain of y = 3(2-x) is that the domain is all real numbers. The domain of the function y = 3(2^-x) is all real numbers, as there are no restrictions on x from the form of the function itself.

The correct statement about the domain of y = 3(2-x) is that the domain is all real numbers. This is because for the function given, there are no restrictions on the values that x can take. The base of the exponent, 2, is positive and since exponents can take any real number, negative or positive, there is nothing to prevent any real x from being used as an input. Furthermore, since the function does not contain any terms that would result in undefined operations, such as division by zero or negative numbers under an even root, the domain remains unrestricted.

Perform the indicated operation.

Division Property of Equality

Answers

If 5x + 7 = 2x - 1, then 3x + 7 = -1

answer is
Subtraction Property of Equality

Answer: The correct option is second, i.e., Subtraction Property of Equality.

Explanation:

The given equation is,

[tex]5x+7=2x-1[/tex]

The Subtraction Property of Equality states that if a, b and c are real numbers then, [tex]a=b[/tex] and [tex]a-c=b-c[/tex] are equivalent equations.

Using Subtraction Property of Equality we subtract 2x from both the sides of given equation,

[tex]5x+7-2x=2x-1-2x[/tex]

Then combined like terms,

[tex](5x-2x)+7=(2x-2x)-1[/tex]

[tex]3x+7=-1[/tex]

It is the required equation.

Hence, second option is correct.
