Distance is increasing with a speed of 0.2 Miles/Min

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Time in Minutes      Distance in Miles

0                              0.0

2                              0.4

4                              0.8

6                              1.2

8                              1.6

Here, Myra’s distance is increasing as time increase with a constant Speed.

Now, In every 2 mins distance traveled = 0.4 Miles

Hence, In every 1 min Distance traveled = 0.4/2 = 0.2 Miles/Min

Thus, Distance is increasing with a speed of 0.2 Miles/Min.

The product of linear factors of the polynomial h(x) will be (x + 1), (x + 1 + √7), and (x + 1 - √7).

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The cubic polynomial is given below.

h(x) = x³ + 3x² - 4x - 6

Factorize the polynomial, then we have

h(x) = x³ + 3x² - 4x - 6

h(x) = x³ + x² + 2x² + 2x - 6x - 6

h(x) = x²(x + 1) + 2x(x + 1) - 6(x + 1)

h(x) = (x + 1)(x² + 2x - 6)

Factorize tbe expression (x² + 2x - 6) by formaula method,

x = [-2 ± √(2² - 4 × 1 × (-6))] / 2 × 1

x = (- 2 ± 2√7) / 2

x = - 1 ± √7

(x + 1 + √7)(x + 1 - √7) = 0

Then we have the factor of the function,

h(x) = (x + 1)(x + 1 + √7)(x + 1 - √7)

The product of linear factors of the polynomial h(x) will be (x + 1), (x + 1 + √7), and (x + 1 - √7).

0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations

To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

Based on the given confidence interval, there is evidence to support the claim that the true average echo duration of lightning flashes is 0.8 seconds.

To determine if the evidence supports the claim that the true average echo duration of lightning flashes is 0.8 seconds, we need to check if the value 0.8 falls within the confidence interval.

The 95% two-sided confidence interval for the true average echo duration is (0.743, 0.877). Since the value 0.8 falls within this interval, it means that the true average echo duration of lightning flashes of 0.8 seconds is within the range of values that is supported by the data.

Therefore, based on the given confidence interval, there is evidence to support the claim that the true average echo duration of lightning flashes is 0.8 seconds.

To find the orthogonal projection of a vector onto a subspace, we can use the formula:

projᵥ(u) = A(AᵀA)⁻¹Aᵀᵤ,

where A is a matrix whose columns span the subspace, and u is the vector we want to project.

In this case, the subspace W is spanned by the vector v = [0, 0, 0, 1].

Let's calculate the orthogonal projection of u onto W using the formula:

A = [v]

The transpose of A is:

Aᵀ = [vᵀ].

Now, let's substitute the values into the formula:

projᵥ(u) = A(AᵀA)⁻¹Aᵀᵤ

= v⁻¹[vᵀ]u

= [v][(vᵀv)⁻¹vᵀ]u

Substituting the values of v and u:

v = [0, 0, 0, 1]

u = [1, 0, 0, 0]

vᵀv = [0, 0, 0, 1][0, 0, 0, 1] = 1

[(vᵀv)⁻¹vᵀ]u = (1⁻¹)[0, 0, 0, 1][1, 0, 0, 0] = [0, 0, 0, 1][1, 0, 0, 0] = [0, 0, 0, 0]

Therefore, the orthogonal projection of u onto the subspace W is [0, 0, 0, 0].

Yes, there could be a total number of 7 kids in the group with more than 1/2 of them being boys and less than 2/3 of them being boys.

Let's assume that the total number of kids in the group is x.

According to the problem, more than 1/2 of the group are boys. Mathematically, we can represent this as:

Number of boys > x/2

Also, the boys are less than 2/3 of the group. Mathematically, we can represent this as:

Number of boys < 2x/3

Now, let's substitute x=7 in the above two equations:

Number of boys > 7/2 = 3.5 --- (1)

Number of boys < 14/3 ≈ 4.67 --- (2)

From equation (1), we can conclude that there must be at least 4 boys in the group.

From equation (2), we can conclude that there can be at most 4 boys in the group because the number of boys cannot be a fraction.

Therefore, the possible number of boys in the group could be either 4 or 3. If there are 4 boys, then the number of girls in the group would be 3. If there are 3 boys, then the number of girls in the group would be 4.

Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

There are a lot of tiles to drag onto the board.

You would need to create a rectangle from 99 tiles.

80 is a multiple of 10, so it has factors of 10 and 8, which add to 18.

The dot product comes zero, so the planes are perpendicular.

To determine whether the planes are parallel, perpendicular, or neither, we need to examine their normal vectors. The normal vector of the first plane can be found by taking the coefficients of x, y, and z, which gives <9, 36, -27>. The normal vector of the second plane can be found similarly, which gives <-12, 24, 28>.
To determine if the planes are parallel, we need to check if their normal vectors are parallel. We can do this by taking the dot product of the two normal vectors. If the dot product is equal to the product of their magnitudes, then they are parallel. If the dot product is zero, then they are perpendicular. If the dot product is neither equal to the product of their magnitudes nor zero, then they are neither parallel nor perpendicular.
Dot product of the two normal vectors: (9)(-12) + (36)(24) + (-27)(28) = -108 + 864 - 756 = 0
Since the dot product is zero, the planes are perpendicular. Therefore, the answer is b) Perpendicular.

y = $5.5

Substitute y = 5.5 into equation 1

From equation 1, 2x + 3y = 23

Answer:

y = (2/5)x + 2

Step-by-step explanation:

To find the inverse of a function, we simply exchange the variables x and y and solve for y.

For this function we will write it as such:

y = -5 + (5/2)x

So to find the inverse, we will swap the x and y and solve.

y = -5 + (5/2)x

x = -5 + (5/2)y

x + 5 = (5/2)y

(2/5) * (x + 5) = y

(2/5)x + (2/5)5 = y

(2/5)x + 2 = y

Thus the inverse of the function is:

-8 < a < 6

Step-by-step explanation:

a > -8 and a < 6

the first inequality can be solved by the balancing method aka performing the same operation on both sides. To isolate the a, we need to subtract 3 from both sides of the sign, which results in a > -8.

The second one can be solved similarly. Again we subtract 3 from both sides which gets us a < 6. This could be the final answer if they are two seperate inequalities. However, if it is one whole question (I dont know the context of the question so I cant assess that), then you are still required to modify the solution a little.

we have a > -8 and a < 6, so a needs to be larger than -8 and smaller than 6. If we change the first one to -8 <  a (essentially meaning the same thing), we can see that we can combine the two solutions:

-8 < a < 6
