Answer:

The suit originally cost $200.

Step-by-step explanation:

In order to calculate the original price of the suit, you can use a rule of three considering that $116 represents 58% of the original price:

116 → 58%

x  ←  100%

x=(116*100)/58

x=200

According to this, the answer is that the suit originally cost $200.

a) Negation of ∼ p∧ ∼ q is (p V q). The original statement "∼ p∧ ∼ q" has a negation of "p V q" using DeMorgan's law of negation that states: The negation of a conjunction is a disjunction in which each negated conjunct is asserted.

b) Negation of (p ∧ q) → r is (p ∧ q) ∧ ∼r. The original statement "(p ∧ q) → r" has a negation of "(p ∧ q) ∧ ∼r" using DeMorgan's law of negation that states: The negation of a conditional is a conjunction of the antecedent and the negation of the consequent.

DeMorgan's law of negation is applied to get the negation of the given statements as shown below:(a) ∼ p∧ ∼ qNegation of the above statement is(p V q)DeMorgan's law of negation is used to get the negation of the statement(b) (p ∧ q) → rNegation of the above statement is(p ∧ q) ∧ ∼r DeMorgan's law of negation is used to get the negation of the statement.

The given statement (a) is ∼ p∧ ∼ q. The negation of the statement is obtained by applying DeMorgan's law of negation. The law states that the negation of a conjunction is a disjunction in which each negated conjunct is asserted. Hence, the negation of ∼ p∧ ∼ q is (p V q).

For the given statement (b) which is (p ∧ q) → r, the negation is obtained using DeMorgan's law of negation. The law states that the negation of a conditional is a conjunction of the antecedent and the negation of the consequent. Hence, the negation of (p ∧ q) → r is (p ∧ q) ∧ ∼r.

DeMorgan's law of negation is a fundamental tool in logic that is used to obtain the negation of a given statement. The law is applied to negate a conjunction, disjunction, or conditional statement. To obtain the negation of a statement, the law is applied as many times as required until the desired negation is obtained.

Az = λz, which means that any nonzero linear combination of x and y (such as z) is also a right eigenvector associated with the eigenvalue λ.

to show that any nonzero linear combination of x and y is also a right eigenvector associated with the eigenvalue λ, we can start by considering a nonzero scalar α. let z = αx + βy, where α and β are scalars. now, let's evaluate az:

az = a(αx + βy) = αax + βay.since x and y are eigenvectors of a associated with the eigenvalue λ, we have:

ax = λx,ay = λy.substituting these equations into the expression for az, we get:

az = α(λx) + β(λy) = λ(αx + βy) = λz. to conclude that the set of all eigenvectors associated with a particular λ, together with the zero vector, forms a subspace of cn, we need to show that this set is closed under addition and scalar multiplication.1. closure under addition:

let z1 and z2 be nonzero linear combinations of x and y, associated with λ. we can express them as z1 = α1x + β1y and z2 = α2x + β2y, where α1, α2, β1, β2 are scalars. now, let's consider the sum of z1 and z2:z1 + z2 = (α1x + β1y) + (α2x + β2y) = (α1 + α2)x + (β1 + β2)y.

since α1 + α2 and β1 + β2 are also scalars, we can see that the sum of z1 and z2 is a nonzero linear combination of x and y, associated with λ.2. closure under scalar multiplication:

let z be a nonzero linear combination of x and y, associated with λ. we can express it as z = αx + βy, where α and β are scalars.now, let's consider the scalar multiplication of z by a scalar c:cz = c(αx + βy) = (cα)x + (cβ)y.

since cα and cβ are also scalars, we can see that cz is a nonzero linear combination of x and y, associated with λ.additionally, it's clear that the zero vector, which can be represented as a linear combination with α = β = 0, is also associated with λ.

The given statement "If the graphs of f an g intersect midway between x=a and x=b, then the integral from a to b [f(x)-g(x)]dx= 0" is a FALSE statement.

The given statement "If the graphs of f an g intersect midway between x=a and x=b, then the integral from a to b [f(x)-g(x)]dx= 0" is a FALSE statement. What is meant by the word intersect? The point where two lines cross each other is known as the intersection point. We know that in mathematics, two lines can intersect at a single point or may never intersect at all.

Let us consider two different functions f(x) and g(x) and assume that they intersect midway between x=a and x=b as shown in the below figure.Then, we can conclude that at the point of intersection, both the function has the same value. That is, f(c) = g(c).Where c is the value of the point of intersection. To check whether the given statement is true or false, let us find the integral from a to b of [f(x) - g(x)] dx.The area of the shaded region in the above graph is equal to the integral of [f(x) - g(x)] from a to b. Since the graphs of f and g intersect at c, then both the function has the same value at x = c.

This implies that f(c) = g(c).From the graph, it is clear that f(x) > g(x) when x is between a and c and g(x) > f(x) when x is between c and b. That is, [f(x) - g(x)] > 0 for x in [a, c) and [g(x) - f(x)] > 0 for x in (c, b]. Therefore, the integral from a to b of [f(x) - g(x)] dx is not equal to zero. Thus, the given statement "If the graphs of f an g intersect midway between x=a and x=b, then the integral from a to b [f(x)-g(x)]dx= 0" is a FALSE statement.

Answer:

D = √[(x2 - x1)² + (y2 - y1)²]

Step-by-step explanation:

Given a right-angled triangle, with sides: Hypotenuse D, and opposites (x2 - x1) and (y2 - y1).

Then by Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the opposite side.

That is,

D² = (x2 - x1)² + (y2 - y1)²

Now, taking square roots of both side, we have the formula for the distance or length D.

D = √[(x2 - x1)² + (y2 - y1)²]

The new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees are approximately (4.993, 2.048).

To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:

x' = x * cos(theta) - y * sin(theta)

y' = x * sin(theta) + y * cos(theta)

Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.

Converting the angle of rotation from degrees to radians:

theta = 5 degrees * (pi/180) ≈ 0.08727 radians

Plugging in the values into the rotation formula:

x' = 5 * cos(0.08727) - 2 * sin(0.08727)

y' = 5 * sin(0.08727) + 2 * cos(0.08727)

Evaluating the trigonometric functions and simplifying:

x' ≈ 4.993

y' ≈ 2.048

Answer:

15 quarters

Step-by-step explanation:

Assuming q = quarters and d = dimes...

First, set up the equations. q + d = 28 since we have 28 coins, and the latter is because a quarter is worth $0.25 and a dime is worth $0.1 - totaling $5.05.

q + d = 28

.25q + .10d = 5.05

Try to get one of the variables equal to the equation above. In this case, I tried to get the "q" variables equal to each other.

q + d = 28

4(.25q + .10d) = 4(5.05)

After this, you "subtract" the two equations from each other. Remember that d = 1d, and 1 - .4 = .6

q + d = 28

q + .4d = 20.20

Divide both sides by .6 to get d by itself.

.6d = 7.8

There are 13 dimes.

d = 13

Subtract 13 from the total coins (28) to get the amount of quarters.

28 - 13 = 15

13 dimes, 15 quarters. Hope this helped!

To solve for taxes in equilibrium, we can start by substituting the given equations into the equation for YD:

YD = Y - T

Since C and T are constant, we can write:

YD = (c0 + c1YD) - (t0 + t1Y)

Now, we can rearrange the equation to isolate YD:

YD = c0 + c1YD - t0 - t1Y

Simplifying further:

YD - c1YD = c0 - t0 - t1Y

Factoring out YD:

YD(1 - c1) = c0 - t0 - t1Y

Dividing both sides by (1 - c1):

YD = (c0 - t0 - t1Y) / (1 - c1)

Now, let's analyze the effects of a drop in c0. If c0 decreases, it implies that consumption decreases. As a result, YD will decrease, leading to a decrease in Y. Taxes will also decrease because they are determined by YD.

If the government cuts spending to balance the budget, it will lead to a decrease in G. This decrease in spending will reduce Y and further decrease YD. However, the impact on Y will depend on the magnitude of the cut in spending.

If the cut in spending is significant, it can counteract the decrease in output caused by the drop in c0. On the other hand, if the cut in spending is small, it may reinforce the effect of the drop in c0 on output. The overall effect on Y will depend on the relative magnitudes of the changes in c0 and G.

A drop in c0 will decrease both Y and taxes in equilibrium. If the government cuts spending to balance the budget, the effect on Y will depend on the magnitude of the cut in spending relative to the decrease in c0.

The cut in spending required to balance the budget counteracts the effect of the drop in c₀ on output (Y).

In equilibrium, taxes can be solved using the given equations:

C = c₀ + c₁YD

T = t₀+ t₁Y

YD = Y – T

To find taxes in equilibrium, we need to substitute the value of YD into the equation for taxes:

T = t₀ + t₁YD

Now, let's analyze the impact of a drop in c₀ on output (Y) and taxes (T).

When c₀ decreases, it means that the intercept of the consumption function (C) decreases.

This results in a decrease in consumption at every level of income. As a result, the aggregate demand decreases, leading to a decrease in output (Y).

The decrease in output (Y) leads to a decrease in income and, consequently, a decrease in disposable income (YD).

Since taxes (T) depend on disposable income, a decrease in YD will lead to a decrease in taxes (T).

Next, let's consider the effect of a government spending cut to balance the budget.

When the government cuts spending to balance the budget, it reduces its expenditure (G) without changing its tax revenue (T).

This reduction in government spending decreases aggregate demand, which in turn reduces output (Y).

However, since the government is keeping the budget balanced, the decrease in government spending is offset by the decrease in taxes (T) that occurs as a result of the decrease in output (Y).

Therefore, the cut in spending required to balance the budget counteracts the effect of the drop in c₀ on output (Y).
