In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.

Answer: `(BC)^2/(AB)^2`.

The ladder will reach a height of 8 feet, which is greater than 7 feet. So, the ladder will indeed reach 7 feet high, and even higher.

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse.

We can use the Pythagorean theorem to determine if the ladder will reach 7 feet high. Let's let x be the height that the ladder reaches, as shown in the diagram below:

According to the Pythagorean theorem, we have:

\($\begin{align*}x^2 + 6^2 &= 10^2 &= 100 - 36 &= 64 \x &= \sqrt{64} \x &= 8\end{align*}\)

Therefore, the ladder will reach a height of 8 feet, which is greater than 7 feet. So, the ladder will indeed reach 7 feet high, and even higher.

The vector is unique. this is correct answer.

To find a vector whose image under the linear transformation T is b, we need to solve the equation T(x) = Ax = b.

Given:

A = 4  47

      -1 -1

b = -13

       -9

        6

Let's find the vector x by solving the equation Ax = b. We can write the equation as a system of linear equations:

4x₁ + 47x₂ = -13

-x₁ - x₂ = -9

We can use various methods to solve this system of equations, such as substitution, elimination, or matrix inversion. Here, we'll use the elimination method.

Multiplying the second equation by 4, we get:

-4x₁ - 4x₂ = -36

Adding this equation to the first equation, we have:

4x₁ + 47x₂ + (-4x₁) + (-4x₂) = -13 + (-36)

This simplifies to:

43x₂ = -49

Dividing by 43:

x₂ = -49/43

Substituting this value of x₂ into the second equation, we get:

-x₁ - (-49/43) = -9

-x₁ + 49/43 = -9

-x₁ = -9 - 49/43

-x₁ = (-9*43 - 49)/43

-x₁ = (-387 - 49)/43

-x₁ = -436/43

So, the vector x is:

x = (-436/43, -49/43)

Now, we can find the image of this vector x under the linear transformation T(x) = Ax:

\(T(x) = A * x = A * (-436/43, -49/43)\)

Multiplying the matrix A by the vector x, we have:

\(T(x) = (-436/43 * 4 + (-49/43) * (-1), -436/43 * 47 + (-49/43) * (-1))\)

Simplifying:

\(T(x) = (-1744/43 + 49/43, -20552/43 + 49/43)\)

\(T(x) = (-1695/43, -20503/43)\)

Therefore, the vector whose image under the linear transformation T is b is:

(-1695/43, -20503/43)

To determine if this vector is unique, we need to check if there is a unique solution to the equation Ax = b. If there is a unique solution, then the vector would be unique. If there are multiple solutions or no solution, then the vector would not be unique.

Since we have found a specific vector x that satisfies Ax = b, and the solution is not dependent on any arbitrary parameters or variables, the vector (-1695/43, -20503/43) is unique.

Answer:

\(m\widehat{VU}=120^{\circ}\)

Step-by-step explanation:

The angle \(\angle TUV\) forms arc \(\widehat{TV}\). The measure of this arc is twice the measure of angle \(\angle TUV\), since \(U\) is a point on the circle. Since \(\overline{TU}\) forms an arc \(\widehat{TU}\), we can set up the following equation:

\(\widehat{TV}+\widehat{VU}=\widehat{TU}\).

Since arc TU represents half of a circle and there are 360 degrees in a circle, we can substitute the following values and solve for the measure of arc VU:

\(\\2\cdot 30^{\circ}+\widehat{VU}=180^{\circ},\\60^{\circ}+\widehat{VU}=180^{\circ},\\m\widehat{VU}=\boxed{120^{\circ}}\)

The distance between coordinates (2, 4) and (4, 3) is found to be √5.

The coordinates (2, 4) and (4, 3) in a figure are the endpoints of a line segment.

A line segment is the part of the line that connects two distinct points.

It has a definite length, and it is bounded at each end by a point. Therefore, the two points have this in common.

The distance between the points (2, 4) and (4, 3) can be calculated using the distance formula.

The distance formula for two points on a coordinate plane, (x1, y1) and (x2, y2), is as follows:

Distance = √(x2 − x1)2 + (y2 − y1)2

Using this formula for (2, 4) and (4, 3), we get:

Distance = √(4 − 2)2 + (3 − 4)2

= √22 + (−1)2= √4 + 1

= √5

Therefore, the distance between (2, 4) and (4, 3) is √5.

To find the value of p(b), we can use the formula for conditional probability:

p(a|b) = p(a ∩ b) / p(b)

Since a and b are independent events, p(a ∩ b) = p(a) * p(b). Substituting this into the formula, we have:

0.60 = (0.60 * p(b)) / p(b)

Simplifying, we can cancel out p(b) on both sides of the equation:

0.60 = 0.60

This equation is true for any value of p(b), as long as p(b) is not equal to zero. Therefore, we can conclude that p(b) can be any non-zero value.

In summary, the value of p(b) is not uniquely determined by the given information and can take any non-zero value.

Step-by-step explanation:

(c) The student misses the bus by the difference between the total distances covered by the bus and the student.

(a) To determine the distance covered by the bus from the moment the student starts chasing it until the moment the bus passes by the stop, we need to consider the relative motion between the bus and the student. Let's break down the problem into two parts:

1. Acceleration phase of the student:

During this phase, the student accelerates until reaching the bus's velocity. The initial velocity of the student is zero, and the final velocity is the velocity of the bus. The time taken by the student to accelerate is given as 1.70 s.

Using the equation of motion:

v = u + at

where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time, we can calculate the acceleration of the student:

a = (v - u) / t

  = (0 -\(v_{bus}\)) / 1.70

Since the student starts 200 m ahead of the bus, we can use the following kinematic equation to find the distance covered during the acceleration phase:

s = ut + (1/2)at^2

Substituting the values:

\(s_{acceleration}\) = (0)(1.70) + (1/2)(-\(v_{bu}\)s/1.70)(1.70)^2

              = (-\(v_{bus}\)/1.70)(1.70^2)/2

              = -\(v_{bus}\)(1.70)/2

2. Constant velocity phase of the student:

Once the student reaches the velocity of the bus, both the bus and the student will cover the remaining distance together. The time taken by the bus to cover the remaining distance of 200 m is given as 36 s - 1.70 s = 34.30 s.

The distance covered by the bus during this time is simply:

\(s_{constant}_{velocity} = v_{bus}\) * (34.30)

Therefore, the total distance covered by the bus is:

Total distance = s_acceleration + s_constant_velocity

              = -v_bus(1.70)/2 + v_bus(34.30)

Since the distance covered cannot be negative, we take the magnitude of the total distance covered by the bus.

(b) To determine the distance covered by the student during the 36 s, we consider the acceleration phase and the constant velocity phase.

1. Acceleration phase of the student:

Using the equation of motion:

s = ut + (1/2)at^2

Substituting the values:

\(s_{acceleration}\) = (0)(1.70) + (1/2\(){(a_student)}(1.70)^2\)

2. Constant velocity phase of the student:

During this phase, the student maintains a constant velocity equal to that of the bus. The time taken for this phase is 34.30 s.

The distance covered by the student during this time is:

\(s_{constant}_{velocity} = v_{bus}\) * (34.30)

Therefore, the total distance covered by the student is:

Total distance =\(s_{acceleration} + s_{constant}_{velocity}\)

Cash flow from assets is used to determine the changes in the cash balance of a company. Net capital spending is the amount that the company has invested into its business, which includes capital expenditure, net of depreciation.

As Operating cash flow = EBIT + Depreciation – Taxes

= $460 + $108 – $95 = $473 (in thousands)

We know, Net capital spending = Ending Net Fixed Assets – Beginning Net Fixed Assets + Depreciation

= $315 – $180 + $40

= $175 (in thousands)

Change in NWC = Ending NWC – Beginning NWC

= $260 – $180 = $80 (in thousands)

As Cash flow from assets = Operating cash flow – Net capital spending – Change in NWC

= $473 – $175 – $80

= $218 (in thousands)

Cash flow to creditors = Interest paid – Net new borrowing

= $95 – $50 = $45 (in thousands)

We know, Cash flow to stockholders = Dividends – Net new equity raised

= $77 – $282

= -$205 (in thousands)

To calculate the internal growth rate, we need to find out the sustainable rate of return and the plowback ratio. Sustainable rate of return = (1 - Dividend payout ratio) x Return on equity (ROE)

= (1 - $77/$288) x $288/$1,500

= 0.70 x 0.192

= 0.1344

Plowback ratio = Addition to retained earnings ÷ Net income

= ($288 – $77) ÷ $288

= 0.7326

Internal growth rate = Sustainable rate of return x Plowback ratio

= 0.1344 x 0.7326

= 0.0985 or 9.85%

As Sustainable growth rate = (ROE x Retention ratio) ÷ (1 - ROE x Retention ratio)

= ($288/$1,500) x (1 - $77/$288) ÷ (1 - $288/$1,500 x (1 - $77/$288)

= 0.192 x 0.7326 ÷ (1 - 0.192 x 0.7326)

= 0.1415 or 14.15%

The internal growth rate is the maximum growth rate a company can achieve without raising additional equity or debt, assuming that the company doesn't pay any dividends.

Sustainable growth rate is defined as the maximum growth rate that any company can achieve without raising additional equity or debt and assuming that company maintains a constant debt-to-equity ratio.

The difference between the two is that the internal growth rate assumes that a company can't raise additional equity or debt, while the sustainable growth rate assumes that a company can raise equity or debt to maintain a constant debt-to-equity ratio.

The interval on which the function f(x) = x^4 - 8x^2 + 9 is increasing can be expressed in interval notation as (-∞, -2) ∪ (2, ∞). The interval on which the function is decreasing can be expressed as (-2, 2).

To determine the intervals of increasing and decreasing, we need to examine the derivative of the function. Taking the derivative of f(x) with respect to x gives us f'(x) = 4x^3 - 16x. To find the intervals of increasing and decreasing, we need to analyze the sign of the derivative. The derivative is positive when x < -2 and x > 2, indicating an increasing function. The derivative is negative when -2 < x < 2, indicating a decreasing function.

Answer:

Mark ate 3.3 times the square inches of pizza than Joannie ate.

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr (where r is the radius). If the circumference of a small pizza is 12π inches, then its radius is:

\(\implies \sf Radius_{small\;pizza}=\dfrac{circumference}{2\pi}=\dfrac{12\pi}{2\pi}=6\;inches\)

The formula for the area of a circle is A = πr² (where r is the radius).

Therefore, the area of a small pizza is:

\(\implies \sf Area_{small\;pizza}=\pi \cdot 6^2=36\pi \; in^2\)

If the small pizzas are cut into 6 congruent pieces, the area of one slice of small pizza is:

\(\begin{aligned}\implies \sf Area_{small\;slice}&=\sf \dfrac{Area_{small\;pizza}}{6}\\\\&=\dfrac{36 \pi}{6}\\\\&=6 \pi \; \sf in^2\end{aligned}\)

Therefore, the area of one slice of small pizza is 6π square inches.

\(\hrulefill\)

The diameter of a circle is twice its radius.

If the diameter of a large pizza is 16 inches then its radius is:

\(\implies \sf Radius_{large\;pizza}=\dfrac{diameter}{2}=\dfrac{16}{2}=8\;inches\)

The formula for the area of a circle is A = πr² (where r is the radius).

Therefore, the area of a large pizza is:

\(\implies \sf Area_{large\;pizza}=\pi \cdot 8^2=64 \pi \; in^2\)

If the large pizzas are cut into 8 congruent pieces, the area of one slice of large pizza is:

\(\begin{aligned}\implies \sf Area_{large\;slice}&=\sf \dfrac{Area_{large\;pizza}}{8}\\\\&=\dfrac{64 \pi}{8}\\\\&=8 \pi \; \sf in^2\end{aligned}\)

Therefore, the area of one slice of large pizza is 8π square inches.

\(\hrulefill\)

If Joannie eats 2 slices of small pizza, the square inches of pizza she ate is:

\(\implies \sf Joannie=2 \times 6 \pi = 12 \pi\;in^2\)

If Mark eats 5 slices of large pizza, the square inches of pizza he ate is:

\(\implies \sf Mark =5 \times 8 \pi = 40\pi\;in^2\)

To calculate how many times greater are the square inches of pizza that Mark ate than the square inches of pizza that Joannie ate, divide the area Mark ate by the area Joannie ate:

\(\implies \sf \dfrac{40 \pi}{12 \pi} = \dfrac{10}{3}=3.3\;(nearest\;tenth)\)

Therefore, Mark ate 3.3 times the square inches of pizza than Joannie ate.
