Manny walked a total of . The reference point used to calculate the total distance that he walked was the same as the ending point. Which describes where Manny most likely walked?from the bottom of a hill to the topon a circular nature trailon a sidewalk from his house to the mallfrom the beginning of a straight track to the end
Answers
Manny walked more likely on the circular nature trail.
As a circular path always starts and ends at the same location, we may infer this from the fact that the reference point at the beginning and finish was the same.
Other situations, like going up a slope from the bottom, exclude using the same reference point.
The beginning point and finishing point on a sidewalk or a straight track cannot have the same reference point, in a similar manner.
Therefore we can say that
Manny followed a circular nature route in this manner.The bottom of the hill serves as a reference point as well as the summit, and the beginning point and ending point are the same. Manny is now moving in a circle.Hence, Manny walked more likely on the circular nature trail.

For which values of x will the rational expression below be undefined? Check
all that apply.
(x - 1)(x + 1)
X + 2
A. -1
B. 1
C. -2
D. 2
E. -5
F 5
Answers
Answer:
-2
Step-by-step explanation:
For the given expression to be undefined, this means that the denominator must be zero.
From the given expression, the denominator is x + 2
Equating this to zero;
x+2 = 0
Subtract 2 from both sides
x+2-2 = 0 -2
x = -2
Hence the value of x that makes it undefined is -2
asking whether the linear system corresponding to an augmented matrix [a1 a2 a3 b] has a solution amounts to asking whether b is in span {a1, a2, a3}.
Answers
To determine if the linear system corresponding to an augmented matrix [a1 a2 a3 b] has a solution, we can check whether the vector b is in the span of the vectors {a1, a2, a3}.
In linear algebra, the augmented matrix represents a system of linear equations. The columns a1, a2, and a3 correspond to the coefficients of the variables in the system, while the column b represents the constants on the right-hand side of the equations. To check if the system has a solution, we need to determine if the vector b is a linear combination of the vectors a1, a2, and a3.
If the vector b lies in the span of the vectors {a1, a2, a3}, it means that b can be expressed as a linear combination of a1, a2, and a3. In other words, there exist scalars (coefficients) that can be multiplied with a1, a2, and a3 to obtain the vector b. This indicates that there is a solution to the linear system.
On the other hand, if b is not in the span of {a1, a2, a3}, it implies that there is no linear combination of a1, a2, and a3 that can yield the vector b. In this case, the linear system does not have a solution.
Therefore, determining whether the vector b is in the span of {a1, a2, a3} allows us to determine if the linear system corresponding to the augmented matrix [a1 a2 a3 b] has a solution or not.

how do i solve (4x-5)/(3x+5)>=3?
Answers
Answer:
x = -4
Step-by-step explanation:
(4x-5)/(3x+5) = 3
1. Multiply both sides by 3x+5
4x-5 = 3(3x+5)
2. Expand
4x-5 = 9x+15
3. -4x from both sides
-5 = 5x+15
4. -15 from both sides
-20 = 5x
x = -4
It is greater than 3

Is it true that If B is produced by multiplying row 3 of A by 5, then detB = 5â‹…det A.
Answers
B by replacing the third row of A with the third row of A_3, we obtain
B = [1 2 3; 4 5 6; 35 40 45], and
det(B) = 5 × det(A) = 5 × (-3) = -15.
detB = 5⋅det A
Depends on the matrix B is constructed from the matrix A with its third row multiplied by 5, and it is not necessarily true in general.
If B is produced by multiplying row 3 of A by 5, then it is not necessarily true that detB = 5⋅det A.
Multiplying a row of a matrix by a scalar k multiplies the determinant of the matrix by k, so if we denote A_3 as the matrix obtained by multiplying row 3 of A by 5, we have det(A_3) = 5 × det(A).
The determinant of the resulting matrix B depends on the specific way in which row 3 was used to construct B.
Consider the matrix A = [1 2 3; 4 5 6; 7 8 9].
If we multiply row 3 of A by 5 to obtain A_3 = [1 2 3; 4 5 6; 35 40 45], then det(A_3) = 5 × det(A) = 5 × 0 = 0, since the third row of A_3 is a linear combination of the first two rows.

Answers
Answer:
48 people is the right answer.Step-by-step explanation:
Let the number of male and female be 3x and 5x
There are twelve more females than males
According to the above problem,
\(5x - 3x=12\\ 2x = 12\\ x = \frac{12}{2} \\ \boxed{x = 6}\)
Therefore, the numbers of male is
\(3x = 3 \times 6 = 18\)
and number of female is
\(5x = 5 \times 6 = 30\)
Hence, total number of people are
\((30 + 18) = 48\)

a) Balance ≈ $2801.97, Interest = $301.97b) Balance ≈ $2804.63, Interest = $304.63c) Balance ≈ $2806.54, Interest = $306.54d) Balance ≈ $2809.60, Interest = $309.60How to solve for the balance and the interesta) a) 1.7% interest annually?If you earn 1.7% interest annually, the balance in the account after 4 years would be:
Balance = $2500 × (1 + 0.017)^4 ≈ $2801.97
The interest earned would be the difference between the balance and the initial investment:
Interest = $2801.97 - $2500 = $301.97
b) 1.5% compounded monthly?If you earn 1.5% interest compounded monthly, we need to first calculate the monthly interest rate:
Monthly rate = 1.5% / 12 = 0.125%
The balance in the account after 4 years would be:
Balance = $2500 × (1 + 0.00125)^48 ≈ $2804.63
The interest earned would be the difference between the balance and the initial investment:
Interest = $2804.63 - $2500 = $304.63
c) 1.2 compounded daily?If you earn 1.2% interest compounded daily, we need to first calculate the daily interest rate:
Daily rate = 1.2% / 365 = 0.003288%
The balance in the account after 4 years would be:
Balance = $2500 × (1 + 0.00003288)^1460 ≈ $2806.54

Interest = $2806.54 - $2500 = $306.54
d) 0.7% compounded continuously?If you earn 0.7% interest compounded continuously, we use the formula:
Balance = $2500 × e^(0.007 × 4) ≈ $2809.60
The interest earned would be the difference between the balance and the initial investment:

A cake shop bakes a variety of brownies. the top-selling brownies are ones with toppings of chocolate chip, walnuts, or both. a customer enters the store. the probability that the customer will pick both toppings is 0.4. what is the probability that they will pick neither the chocolate chip nor the walnut toppings?
Answers
The probability that the customer will pick neither the chocolate chip topping nor the walnut topping is 0.6.
What is probability?Probability refers to the chance of occurrence of an event.
Let E be an event. Then, the probability of E = P(E)
=> P(E) = \(\frac{Number Of Favourable Outcomes Of Event E}{Total Number Of Outcomes}\)
Given: The probability that the customer will take both toppings = 0.4
We know that the total probability of an event occurring = 1.
Thus, the probability that the customer will take neither the chocolate chip toppings nor the walnut toppings = 1 - 0.4 = 0.6

Evaluate the surface integral. ∬ S xyzdS,S is the cone with parametric equations x=ucos(v),y=usin(v),z=u,0≤u≤2,0≤v≤ 2 π
Answers
The value of the surface integral is `8(5√5 - 2√2 - 1)/15`.
The surface integral can be evaluated by first calculating the surface area element `dS` of the cone with given parametric equations. `dS` is obtained by finding the cross product of the partial derivatives of `x(u,v), y(u,v)`, and `z(u,v)` with respect to `u` and `v`.
Then, the surface integral can be calculated by integrating the product of `xyz` and `dS` over the surface `S`. Here's how to evaluate the surface integral:
Given that `S` is the cone with parametric equations `x=ucos(v), y=usin(v), z=u`, `0≤u≤2`, `0≤v≤2π`.
The surface area element `dS` of the cone is given by: `dS = |r_u × r_v| du dv`where `r(u, v) = `.
Then, the partial derivatives of `r(u, v)` with respect to `u` and `v` are:`r_u = ` and `r_v = <-u sin(v), u cos(v), 0>`
Thus, the surface area element `dS` can be calculated as:
dS = |r_u × r_v| du dv= |<-u cos(v), -u sin(v), u>| du dv= u √(1+u²) du dv
Therefore, the surface integral ∬S xyz dS can be evaluated as follows:
`∬S xyz dS`=`∬(xyz) (u√(1+u²)) du dv` `(` using dS above `)``
= ∫(0 to 2π) [ ∫(0 to 2) [ ∫(0 to u) (u cos(v) * u sin(v) * u) u √(1+u²) du ] dv ]`
=` ∫(0 to 2π) [ ∫(0 to 2) [ u^5/5 * cos(v) * sin(v) * √(1+u²)/2 ] dv ] du`
(using the formula `∫cosθsinθdθ = (sin²θ)/2`)`
= ∫(0 to 2π) [ ∫(0 to 2) [ u^5/10 * sin(2v) * √(1+u²) ] dv ] du`
(simplifying further using `sin(2v) = 2sin(v)cos(v)`)
=` 8 ∫(0 to 2) [ u^5/10 √(1+u²) ] du`=` 8/15 [ (1+u²)^(5/2) - 1 ]
[from 0 to 2]`=` 8/15 [ (5√5 - 2√2) - 1 ]`
=` 8/15 (5√5 - 2√2 - 1)`
=` 8(5√5 - 2√2 - 1)/15`

The formula for relating a man's shoe size S and the length of his foot L in inches is
S3L
26. Find the length of a man's foot if he wears a size 12 shoe.
Answers
Answer:
12 5/6 inches
Step-by-step explanation:
You want to find the value of L when S=12 1/2, using the formula S = 3L -26.
Foot lengthYou can substitute for S in the formula before or after you solve for L. Here, we'll solve for L first:
S +26 = 3L . . . . add 26 to both sides
(S +26)/3 = L . . . . divide both sides by 3
Substituting 12 1/2 for S, this becomes ...
L = (12 1/2 +26)/3 = (38 1/2)/3 = (77/2)/3 = 77/6 = 12 5/6
A man's foot is 12 5/6 inches long if he wears a size 12 1/2 shoe.
