The quotient of dividing 100 by 42 is equal to 2 with a remainder of 16.

This is because 42 multiplied by 2 is 84, which is the largest multiple of 42 that is less than or equal to 100. Subtracting 84 from 100 gives 16 as the remainder.

The process of division involves dividing a number into equal parts or groups. The result of a division operation is known as the quotient. When we divide 100 by 42, we are asking how many times 42 goes into 100. The answer is 2 with a remainder of 16. This means that we can divide 42 into 100 two times, with 16 remaining.

We can write this as follows:

100 ÷ 42 = 2

R16, where R stands for remainder.

To check our work, we can multiply the quotient by the divisor and add the remainder:2 × 42 + 16 = 100

Therefore, we can conclude that the quotient of dividing 100 by 42 is 2 with a remainder of 16.

Answer:

I'd say A because this question is just like y and xays.

Step-by-step explanation:

(7.1) basis for the nullspace of A

(7.2) basis for the column space of A

(7.3) rank and nullity of A

(7.4) subset of vectors forming a basis for the space spanned by v₁, v₂, v₃, and v₄.

Additionally, matrices B and D are row equivalent to each other.

For matrix A = [0 1 2; -2 0 3; 1 -1 1; 0 0 17/2]

To find the basis for the nullspace of A, we need to solve the homogeneous equation Ax = 0. This can be done by row reducing the augmented matrix [A | 0] and finding the special solutions. The basis for the nullspace consists of the vectors corresponding to the free variables in the row-reduced echelon form.

To find the basis for the column space of A, we can consider the pivot columns in the row-reduced echelon form of A. The column space consists of all linear combinations of these pivot columns.

The rank of A is the number of linearly independent columns in A, which corresponds to the number of pivot columns in the row-reduced echelon form. The nullity of A is the dimension of the nullspace, which is equal to the number of free variables.

To find a subset of vectors v₁, v₂, v₃, and v₄ that forms a basis for the space spanned by these vectors, we can row reduce the matrix [v₁ v₂ v₃ v₄] and identify the linearly independent columns.

The matrices B and D being row equivalent means that they can be transformed into each other by a sequence of elementary row operations. This implies that they have the same row space and nullspace, as well as the same rank and nullity.

To find:

The equation of a line that is perpendicular to the graph of given line.

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

Equation of given line is

[tex]y=\dfrac{2}{5}x-1[/tex]

Here, slope is [tex]\dfrac{2}{5}[/tex].

We know that, product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]m_2=-\dfrac{5}{2}[/tex]

The slope of perpendicular line is [tex]-\dfrac{5}{2}[/tex].

Only in option C, the slope of the line is [tex]-\dfrac{5}{2}[/tex].

Therefore, the correct option is C.

From the given option the slope of the line -5/2 is shown by the equation  [tex]y=-\dfrac{5}{2}x-4[/tex]   that is option B) and this can be determined by using the slope-intercept form.

Given :

Equation --    [tex]y=\dfrac{2}{5}x-1[/tex]     ---- (1)

First, determine the slope of the given line by using the slope-intercept form. The slope-intercept is given by the equation:

y = mx + c

In the given problem, we calculated the price of a bond with a $1,000 face value, a $50 annual coupon, and six years to maturity when the interest rate is 4%. The price of the bond was found to be $1,160.79.

The calculation of the price of the bond can be done using the following formula:

Price = (Annual Coupon Payment / Interest Rate) x (1 - 1 / (1 + Interest Rate) ^ Years to Maturity) + Face Value / (1 + Interest Rate) ^ Years to Maturity.

The annual coupon payment is $50, the interest rate is 4% or 0.040 and the face value is $1,000. Therefore, the price of the bond is given as:Price = ($50 / 0.040) x (1 - 1 / (1 + 0.040) ^ 6) + $1,000 / (1 + 0.040) ^ 6Price = ($1,250) x (1 - 1 / 1.281) + $747.26Price = $1,160.79.

Therefore, the price of the bond is $1,160.79. The bond offers an annual coupon of $50 and has a face value of $1,000. It has six years to maturity and the interest rate is 4%.

Using the bond pricing formula, we can calculate that the price of the bond is $1,160.79.

In finance, a bond is a type of debt security in which the issuer owes the holders a debt and is obliged to pay interest or repay the principal at a later date, known as maturity.

A bond can be issued by a company, municipality, or government entity as a means of raising capital. The price of a bond is determined by several factors, including its face value, coupon rate, and interest rate.

In the given problem, we are asked to calculate the price of a bond with a $1,000 face value, a $50 annual coupon, and six years to maturity when the interest rate is 4%.

Using the bond pricing formula, we found that the price of the bond is $1,160.79.

This means that if an investor were to buy the bond for this price, they would receive the annual coupon payments of $50 for the next six years and then receive the face value of $1,000 at maturity.

In conclusion, the price of a bond can be calculated using the bond pricing formula. The price of a bond depends on several factors, including its face value, coupon rate, and interest rate. In the given problem, we calculated the price of a bond with a $1,000 face value, a $50 annual coupon, and six years to maturity when the interest rate is 4%. The price of the bond was found to be $1,160.79.

Answer:

Debra needs 14 cups of fertilizer.

Step-by-step explanation:

Step 1:  Find the area of Debra's rectangular vegetable garden:

Before we can determine how many cups of fertilizer she needs, we'll need to know the area of Debra's garden.  This will tell us how many square yards her garden covers.  The formula for the area of a rectangle is given by:

A = lw, where

Thus, we can plug in 9(1)/(3) for l and 12 for w in the rectangle area formula to find A, the area of Debra's garden in square yards:

A = 9(1)/(3) * 12

A = 112

Thus, the area of Debra's garden is 112 square yards.

Step 2:  Create a proportion to find x, the number of cups of fertilizers she needs:

We're told that cups of fertilizer with water are proportional to the square yards of Debra's garden.  Thus, we can create a proportion to find x, the number of cups of fertilizer she needs:

(1)/(8) cups / 1 square yard = x cups / 112 square yards

1/8 = x/112

14 = x

Thus, Debra needs 14 cups of fertilizer since her garden covers 112 square yards.

The probability that the restaurant will receive two or more complaints in the next week is approximately 0.907.

Given that a fast food restaurant keeps record of the number of customer complaints per week and it has had 4 complaints per week. Assume that the number of complaints follows a Poisson distribution. We need to find the probability that the restaurant will receive two or more complaints in the next week. To find the probability of two or more complaints in the next week, we need to subtract the probability of zero or one complaint from 1, since the sum of all probabilities is 1.

So ,P(X ≥ 2) = 1 - P(X < 2). Now, the probability of having no complaints P(X = 0) = (e^-λλ^x)/x!

Putting x = 0 and λ = 4,P(X = 0) = (e^-4 4^0)/0! = 0.0183Approximately P(X = 0) = 0.02

Now, the probability of having one complaint P(X = 1) = (e^-λλ^x)/x!

Putting x = 1 and λ = 4,P(X = 1) = (e^-4 4^1)/1! = 0.0733Approximately P(X = 1) = 0.073

So, P(X < 2) = P(X = 0) + P(X = 1)P(X < 2) = 0.02 + 0.073 = 0.093

Therefore, P(X ≥ 2) = 1 - P(X < 2)P(X ≥ 2) = 1 - 0.093P(X ≥ 2) = 0.907

The graph of y = x^2e^(-2) has a point of inflection at the values of x where the concavity of the curve changes. In mathematical terms, a point of inflection occurs where the second derivative of the function changes sign.

To find the values of x that correspond to the points of inflection, we need to find the second derivative of the function and solve for the values of x that make the second derivative equal to zero or undefined.

First, let's find the first and second derivatives of y = x^2e^(-2):

First derivative:

dy/dx = 2xe^(-2) + x^2(-2)e^(-2) = 2xe^(-2) - 2x^2e^(-2)

Second derivative:

d^2y/dx^2 = 2e^(-2) - 4xe^(-2) = 2e^(-2)(1 - 2x)

Now, set the second derivative equal to zero and solve for x:

2e^(-2)(1 - 2x) = 0

Since e^(-2) is always positive and nonzero, we can ignore it for solving this equation. Therefore:

1 - 2x = 0

2x = 1

x = 1/2

So, the graph of y = x^2e^(-2) has a point of inflection at x = 1/2.
