On September 30, picture perfect physicians invested$100,000 in new medical equipment. What is the new assets, liabilities and equity

Answers

The investment of $100,000 dollars in new medical equipment by the picture perfect physician would constitute as his asset. This would be classified as his non-current assets (equipment is usually classified as non-current assets). If he purchased this on credit, this transaction would affect his liability since this would be a payable on his part. The equity would not change since this is not a transaction that would involve his equity. Assuming that this was a credit transaction, there would be an increase of $100,000 in asset and at the same time, there would be an increase in liability in the amount of $100,000.


A spinner is divided into many sections of equal size. Some sections are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 11 over 20. The probability of the arrow landing on a section colored blue is 6 over 20. What is the probability of the arrow landing on a green-colored section?

Answers

red = 11/20....this tells me that there are 11 red ones and 20 total sections
blue = 6/20...this tells me there is 6 blue ones and 20 total sections

so if the rest are green, and if there are 20 total spaces and 11 are red and 6 are blue....that leaves (20 - 11 - 6) = 3...so 3 are green.

so the probability of picking a green one is 3/20 <==
I just added the 11 and 6 and got 17 so 17 subtract 20 is 3 there are only 3 spaces left. simple ;)

A baseball is hit with an initial upward velocity of 70 feet per second from a height of 4 feet above the ground. The equation h= −16t^2 +70t + 4 models the height in feet t seconds after it is hit. After the ball gets to its maximum height, it comes down and is caught by another player at a height of 6 feet above the ground. About how long after it was hit does it get caught?

Answers

To solve you need to set the equation equal to 6 (the height at which the player caught the ball.

6 = -16t^2 + 70t + 4

Next put the equation in standard form by subtracting 6 from both sides

-16t^2 + 70t - 2 = 0

This equation can be simplified by dividing by 2

-8t^2 + 35t - 1 = 0

This equation cannot be factored, but we can use the quadratic formula to find a value for x. Using the equation above we can find the values for a=-8, b = 35 and c = -1.

using the quadratic formula we can solve for x

-b +/- sqrt(b^2 - 4ac)
-------------------------------
       2a

The solutions are

0.03 and 4.35. as 0.03 seems an unrealistic time to hit and catch a baseball we would expect the time to be 4.35 seconds.
Final answer:

By setting the given height (6 feet) in the height equation and using the quadratic formula to solve for time 't', we get two solutions. Since the ball reaches 6 feet twice in its ascension and decension, the latter value of t = 3.79 seconds would be the time it is caught.

Explanation:

The question is regarding the time at which a baseball, hit with an initial upward velocity and caught at 6 feet above the ground, is caught. Firstly, input the given height of 6 feet into the height equation h= -16t^2 + 70t + 4 and solve for

t

. Based on the quadratic formula, we receive two solutions: t = 3.79 s and t = 0.54 s. Since the ball has two points at which it reaches the height of 6 feet during its trajectory - once while going up and once while coming down - the time when it is caught would be the larger value,

t = 3.79 s

. Therefore, approximately 3.79 seconds after being hit, the ball is caught.

How to write two different pairs of decimals whose sums are 14.1. One pair should involve regrouping

Answers

To solve, first let’s define regrouping:
=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.

So let us have the non-regrouping decimal number: 
=> 8.4
Next, the other regrouping decimal 
=> 5.7

So now let us show how it becomes 14.1:
  8.4
+5.7
14.1

Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
Thus, the answer is 14.1

Answer:

6 miles.

Step-by-step explanation:

We have been given that on a city map 2.5 inches represents 5 miles the library and the bank are 3 inches apart on the map. We are asked to find the actual distance between the library and the bank.

[tex]\frac{\text{Actual distance}}{\text{Map distance}}=\frac{\text{5 miles}}{\text{2.5 inches}}[/tex]

[tex]\frac{\text{Actual distance}}{\text{3 inches}}=\frac{\text{5 miles}}{\text{2.5 inches}}[/tex]

[tex]\frac{\text{Actual distance}}{\text{3 inches}}*\text{3 inches}=\frac{\text{5 miles}}{\text{2.5 inches}}*\text{3 inches}[/tex]

[tex]\text{Actual distance}=\frac{\text{5 miles}}{2.5}*3[/tex]

Answer:

90, 74, 16 degrees

Step-by-step explanation:

Given that a right triangle has side lengths AC = 7 inches, BC = 24 inches, and AB = 25 inches.

We find that

AC square + BC square = AC square

Find the volume v of the described solid s. the base of s is an elliptical region with boundary curve 4x2 + 9y2 = 36. cross-sections perpendicular to the x-axis are isosceles right triangles with hypotenuse in the base.

Answers

[tex]4x^2+9y^2=36\iff\dfrac{x^2}9+\dfrac{y^2}4=1[/tex]

defines an ellipse centered at [tex](0,0)[/tex] with semi-major axis length 3 and semi-minor axis length 2. The semi-major axis lies on the [tex]x[/tex]-axis. So if cross sections are taken perpendicular to the [tex]x[/tex]-axis, any such triangular section will have a base that is determined by the vertical distance between the lower and upper halves of the ellipse. That is, any cross section taken at [tex]x=x_0[/tex] will have a base of length

[tex]\dfrac{x^2}9+\dfrac{y^2}4=1\implies y=\pm\dfrac23\sqrt{9-x^2}[/tex]
[tex]\implies \text{base}=\dfrac23\sqrt{9-{x_0}^2}-\left(-\dfrac23\sqrt{9-{x_0}^2}\right)=\dfrac43\sqrt{9-{x_0}^2}[/tex]

I've attached a graphic of what a sample section would look like.

Any such isosceles triangle will have a hypotenuse that occurs in a [tex]\sqrt2:1[/tex] ratio with either of the remaining legs. So if the hypotenuse is [tex]\dfrac43\sqrt{9-{x_0}^2}[/tex], then either leg will have length [tex]\dfrac4{3\sqrt2}\sqrt{9-{x_0}^2}[/tex].

Now the legs form a similar triangle with the height of the triangle, where the legs of the larger triangle section are the hypotenuses and the height is one of the legs. This means the height of the triangular section is [tex]\dfrac4{3(\sqrt2)^2}\sqrt{9-{x_0}^2}=\dfrac23\sqrt{9-{x_0}^2}[/tex].

Finally, [tex]x_0[/tex] can be chosen from any value in [tex]-3\le x_0\le3[/tex]. We're now ready to set up the integral to find the volume of the solid. The volume is the sum of the infinitely many triangular sections' areas, which are

[tex]\dfrac12\left(\dfrac43\sqrt{9-{x_0}^2}\right)\left(\dfrac23\sqrt{9-{x_0}^2}\right)=\dfrac49(9-{x_0}^2)[/tex]

and so the volume would be

[tex]\displaystyle\int_{x=-3}^{x=3}\frac49(9-x^2)\,\mathrm dx[/tex]
[tex]=\left(4x-\dfrac4{27}x^3\right)\bigg|_{x=-3}^{x=3}[/tex]
[tex]=16[/tex]

The volume [tex]\( V \)[/tex] of the solid [tex]\( S \)[/tex] is 32 cubic units.

To find the volume [tex]\( V \)[/tex] of the solid [tex]\( S \),[/tex] where the base is an elliptical region defined by the equation [tex]\( 4x^2 + 9y^2 = 36 \),[/tex] and the cross-sections perpendicular to the [tex]\( x \)[/tex]-axis are isosceles right triangles with their hypotenuse lying on the base, we proceed as follows:

  The equation [tex]\( 4x^2 + 9y^2 = 36 \)[/tex] represents an ellipse centered at the origin with semi-major axis [tex]\( \sqrt{9} = 3 \)[/tex] along the [tex]\( y \)[/tex]-axis and semi-minor axis [tex]\( \sqrt{4} = 2 \)[/tex] along the [tex]\( x \)[/tex]-axis.

Each cross-section perpendicular to the [tex]\( x \)[/tex]-axis is an isosceles right triangle with its hypotenuse on the elliptical base. The height [tex]\( h(x) \)[/tex] of each triangle at a given [tex]\( x \)[/tex] is determined by the elliptical equation.

  For a fixed [tex]\( x \),[/tex] the corresponding [tex]\( y \)[/tex] values on the ellipse satisfy [tex]\( 4x^2 + 9y^2 = 36 \).[/tex] Solving for [tex]\( y \)[/tex], we get:

[tex]\[ y = \frac{2}{3} \sqrt{36 - 4x^2} \][/tex]

The height  of the triangle is [tex]\( \frac{2}{3} \sqrt{36 - 4x^2} \).[/tex]

  To find the volume [tex]\( V \)[/tex] of the solid [tex]\( S \),[/tex] integrate the area of each triangular cross-section along the [tex]\( x \)[/tex]-axis from [tex]\( x = -3 \) to \( x = 3 \):[/tex]

[tex]\[ V = \int_{-3}^{3} \text{Area of triangle at } x \, dx \][/tex]

The area of each triangle is [tex]\( \frac{1}{2} \cdot \text{base} \cdot \text{height} = \frac{1}{2} \cdot 2h(x) \cdot h(x) = h(x)^2 \).[/tex]

Thus,

[tex]\[ V = \int_{-3}^{3} h(x)^2 \, dx = \int_{-3}^{3} \left( \frac{2}{3} \sqrt{36 - 4x^2} \right)^2 \, dx \][/tex]

[tex]\[ V = \int_{-3}^{3} \frac{4}{9} (36 - 4x^2) \, dx \][/tex]

[tex]\[ V = \frac{4}{9} \int_{-3}^{3} (36 - 4x^2) \, dx \][/tex]

[tex]\[ V = \frac{4}{9} \left[ 36x - \frac{4x^3}{3} \right]_{-3}^{3} \][/tex]

Solving further,

[tex]\[ V = \frac{4}{9} \left[ \left( 36 \cdot 3 - \frac{4 \cdot 27}{3} \right) - \left( 36 \cdot (-3) - \frac{4 \cdot (-27)}{3} \right) \right] \][/tex]

[tex]\[ V = \frac{4}{9} \left[ (108 - 36) - (-108 + 36) \right] \][/tex]

[tex]\[ V = \frac{4}{9} \left[ 72 \right] \][/tex]

[tex]\[ V = \frac{4 \cdot 72}{9} \][/tex]

[tex]\[ V = 32 \][/tex]

Therefore, the volume [tex]\( V \)[/tex] of the solid [tex]\( S \)[/tex] is 32 cubic units.

The arrangement of the 864 cubes would be 18 6 by 8 layers.

 

All 48 would be touching the bottom of the box on the bottom layer and all 48 would be touching the top of the box on the top layer.

 

The cubes along both lengths would be touching the sides of the box for the remaining 16 layers. That would be16 cubes per layer or 256 cubes after counting both sides.

 

The cubes along the width would be touching the ends of the box for those 16 layers. Those need to be eliminated from the count since the corner cubes were already counted as part of the ones touching the sides. 4 cubes have not been previously counted for each width of 6 cubes. Both ends of the 16 layers has 8 cubes per layer or 128 cubes.

 

Therefore, that is 256 (sides) + 128 (ends) + 48 (top) + 48 (bottom) and that totals to 480 cubes touching the box.

The difference between the larger of the two numbers and the smaller of the two numbers.

A - B or B - A (whichever is greater)

If we transpose the digits of a two-digit number A to form B, then:

A = 10a + b, where a is the tens digit and b is the one's digit

B = 10b + a, where b is the tens digit and a is the one's digit

The difference between the two numbers.

= A - B

= (10a + b) - (10b + a)

= 9a - 9b

= 9(a - b)

or

B - A

= (10b + a) - (10a + b)

= 9b - 9a

= 9(b - a)

Either way, the difference is a multiple of 9, so it is always divisible by 9.

Therefore,

The difference is a multiple of 9, so it is always divisible by 9.

Find x. Round your answer to the nearest tenth of a degree.

Answers

Answer: [tex]x=49.6^{\circ}[/tex]

Step-by-step explanation:

In the given figure , we have right triangle with hypotenuse 21 units and the side opposite to angle x is 16 units.

According to the trigonometry,

[tex]\sin \theta = \dfrac{\text{side opposite of }\theta}{\text{Hypotenuse}}[/tex]

So for , the given figure , we have

[tex]\sin x = \dfrac{16}{21}\\\\\Rightarrow\ \sin x\approx0.7619\\\\\Rightarrow\ x=\sin^{-1}(0.7619)=0.8662\text{ radian}[/tex] (using sine calculation)

Convert radian into degrees , we have

[tex]x=0.8662\times\dfrac{180^{\circ}}{\pi}\\\\=0.8662\times\dfrac{180^{\circ}}{3.14159}=49.6319852107\approx49.6^{\circ}[/tex]  [Round to the nearest tenth.]

Hence, [tex]x=49.6^{\circ}[/tex]

In the given right triangle, x = 49.6°

Missing angles of right triangles

The triangle shown is a right triangle

The angle, θ = x

The opposite = 16

The hypotenuse = 21

Using the formula:

[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]

Substitute opposite = 16, hypotenuse = 21, and θ = x into the formula above to solve for x

[tex]sin x = \frac{16}{21} \\\\sin x = 0.7619\\\\x = sin^{-1}0.7619\\\\x=49.6^0[/tex]

Therefore, in the given right triangle, x = 49.6°

Find the area of the helicoid (or spiral ramp) with vector equation r(u, v) = ucos(v) i + usin(v) j + v k, 0 ≤ u ≤ 1, 0 ≤ v ≤ 9π.

Answers

Let [tex]H[/tex] denote the helicoid parameterized by

[tex]\mathbb r(u,v)=u\cos v\,\mathbf i+u\sin v\,\mathbf j+v\,\mathbf k[/tex]

for [tex]0\le u\le1[/tex] and [tex]0\le v\le9\pi[/tex]. The surface area is given by the surface integral,

[tex]\displaystyle\iint_H\mathrm dS=\iint_H\|\mathbf r_u\times\mathbf r_v\|\,\mathrm du\,\mathrm dv[/tex]

We have

[tex]\mathbf r_u=\dfrac{\partial\mathbf r(u,v)}{\partial u}=\cos v\,\mathbf i+\sin v\,\mathbf j[/tex]
[tex]\mathbf r_v=\dfrac{\partial\mathbf r(u,v)}{\partial v}=-u\sin v\,\mathbf i+u\cos v\,\mathbf j+\mathbf k[/tex]
[tex]\implies\mathbf r_u\times\mathbf r_v=\sin v\,\mathbf i-\cos v\,\mathbf j+u\,\mathbf k[/tex]
[tex]\implies\|\mathbf r_u\times\mathbf r_v\|=\sqrt{1+u^2}[/tex]

So the area of [tex]H[/tex] is

[tex]\displaystyle\iint_H\mathrm dS=\int_{v=0}^{v=9\pi}\int_{u=0}^{u=1}\sqrt{1+u^2}\,\mathrm du\,\mathrm dv[/tex]
[tex]=\dfrac{9(\sqrt2+\sinh^{-1}(1))\pi}2[/tex]

The area f the helicoid ramp  is:

∫∫A) | r(u) *r( v) | dudv

The solution is:

A = 10.35×π  square units

r ( u , v ) = u×cosv i +  u×sinv j +v k

To get

r (u ) = δ(r ( u , v ) ) / δu   = [ cosv , sinv , 0 ]

r ( v ) = δ(r ( u , v ) ) / δv  = [ -u×sinv , u×cosv , 1 ]

The vectorial product is:

                                 i                    j              k

r (u ) * r ( v )            cosv             sinv           0

                            -u×sinv           u×cosv       1

r (u ) * r ( v )  =  i × ( sinv - 0 )  - j × ( cosv - 0 ) + k ( u×cos²v + u× sin²v )

r (u ) * r ( v )  = sinv i - cosv j + u k

Now

| r (u ) * r ( v ) |  = √sin²v + cos²v + u²  = √ 1 + u²

Then  

A = ∫₀ (9π) dv    ∫₀¹  √ 1 + u²  du    

 ∫₀¹  √ 1 + u²  du    = 1.15  

A = 1.15 × v |( 0  , 9π )

A = 10.35×π  square units
