14. Imagine a particle starting at (1,0) and making one counterclockwise revolution on the unitcircle. Let t be the angle in standard position that corresponds to the particle's position. At howmany points along the path of the particle are the x and y coordinates equal?

Answers

Let's make a graph to better understand the question:

a.) A particle starting at (1,0) and making one counterclockwise revolution on the unit

circle.

In the given description, we can assume that the center of the circle when the particle makes a revolution is at the origin (0,0). Thus, the equation of the circle that the particle will make is:

[tex](x-h)^2+(y-k)^2\text{ = }r^2[/tex]

At (h,k) = (0,0) and r = distance between (0,0) to (1,0).

We get,

[tex](x-0)^2+(y-k)^2=(\sqrt[]{(1-0)^2+(0-0)^2})^2[/tex][tex]x^2+y^2\text{ = }1[/tex]

Plotting the graph,

In conclusion, there will be two points along the path of the particle that the x and y coordinate equal.

At, x = y, let's substitute this to the formula of the graph of the circle to get the coordinates.

[tex]x^2+y^2\text{ = }1[/tex][tex]x^2+x^2\text{ = }1[/tex][tex]2x^2\text{ = 1 }\rightarrow\text{ }\frac{2x^2}{2}=\text{ }\frac{1}{2}[/tex][tex]x\text{ = }\sqrt[]{\frac{1}{2}}[/tex][tex]x\text{ = y = }\pm\frac{1}{\sqrt[]{2}}[/tex]

Therefore, the two points where the x and y will be equal is at:

Find the area of the triangle with the given measurements. Round the solution to thenearest hundredth if necessary.B = 74º, a = 14 cm, c = 20 cm (5 points)

Answers

Let's begin by listing out the given information:

[tex]\begin{gathered} \angle B=74^{\circ} \\ a=14\operatorname{cm} \\ c=20\operatorname{cm} \end{gathered}[/tex]

We will calculate the area as shown below:

[tex]\begin{gathered} \text{We will obtain the third side using the Cosine Rule:} \\ b^2=a^2+c^2-2ac\cdot cosB \\ b=\sqrt[]{a^2+c^2-2ac\cdot cosB} \\ b=\sqrt[]{14^2+20^2-2(14)(20)\cdot cos74^{\circ}} \\ b=21.02cm \end{gathered}[/tex]

The formula for area is given by Heron's formula:

[tex]\begin{gathered} A=\sqrt[]{s(s-a)(s-b)(s-c)} \\ s=\frac{a+b+c}{2}=\frac{14+21.02+20}{2}=\frac{55.02}{2}=27.51 \\ s=27.51 \\ \Rightarrow A=\sqrt[]{27.51(27.51-14)(27.51-21.02)(27.51-20)} \\ A=134.58cm^2 \end{gathered}[/tex]

if R200 is musted at 6% simple interests per year detemine the interest if earch after 4years

Answers

The interest calculated after 4 years for a principal amount of 200 at 6% rate of interest , is 48 and the total amount is 248.

Given,

P = 200

rate of interest (r) = 6%

time (t) = 4 years.

we know the simple interest formula as:

S.I = P×r×t/100

substitute the above values.

Interest = 200 × 4 × 0.06/100

= 800 × 0.06/100

= 8 × 0.06

= 0.48 × 100

= 48

Total amount = 200+48

= 248

Hence we  get the total amount as 248 at the end of 4 years.

A hemisphere bowl of radius 7ft has water in it to a depth of 2 ft. At what angle must it be tipped for the water to begin to flow out?

Answers

We have an hemisphere (a shape that is half a sphere) of radius r = 7 ft, that is a bowl filled with water up to a depth of 2 ft.

We have to find at what angle must it be tipped for the water begind to flow. We have to take into account that the level of the water will remain horizontal when we tip the bowl.

This will happen when the water level reaches the edge of the hemisphere.

This can be represented as:

The bowl have to be tipped so the edge descends 2 ft.

We can represent that in mathematical terms as:

Then, we can relate the angle with the depth using a trigonometric ratio:

[tex]\begin{gathered} \sin \theta=\frac{\text{opposite}}{\text{hypotenuse}}=\frac{\text{depth}}{\text{radius}}=\frac{2}{7} \\ \theta=\arcsin (\frac{2}{7}) \\ \theta\approx16.6\degree \end{gathered}[/tex]

A giant panda gave birth to her baby at a zoo. The baby panda weighed 100 grams. At its health exam 51 days later the baby weighed 2.17 kilograms. How much weight did the panda cub gain after 51 days?

Answers

Day 1 Weight of Baby Panda = 100 grams

Day 52 (after 51 days) Weight of Baby Panda = 2.17 kg

To determine the weight increase of our baby panda, we have to convert first the units from kg to grams.

[tex]1kg=1000grams[/tex]

Please know that 1kg = 1000 grams. Therefore, 2.17 kg is equal to:

[tex]2.17kg\times1000grams=2170grams[/tex]

So now, the weight of our baby panda after 51 days is 2170 grams. To determine weight increase, we will subtract 100 grams from 2170 grams.

[tex]2,170grams-100grams=2,070grams[/tex]

Therefore, the panda cub gained 2,070 grams after 51 days or 2.07kg.

How many ounces of water must be added to 85oz of a 40% salt solution to make a solution that is 17% salt?

Answers

Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following:

Accordingly, since the amount of salt remains the same, then we have the following equality, where x represents the amount of water that must be added:

0.4(85)=0.17(x+85)

Let's solve for x:

34=0.17x+14.45

0.17x=34-14.45

0.17x=19.55

x=19.55/0.17

x=115

Finally we obtain that must be added 115 ounces of water to make a solution that is 17% salt.

There is no point at -4 1/2 or -2 1/2 on this graph

b) coordinates: (-2, -3), (3, 1/2)

Tere is no x value at -4 1/2 or -2 1/2 on this graph

c) when x = -2 1/2, y = -2

when x = 4 1/2, y = 1

d) There is no x value at 4 1/2 on this graph. There is also no x value at -2 1/2 on this graph

Hence, the coordinate plane that contains points (4 1/2, 1) and (-2 1/2, -2) is option C

If the line joining the points (a,4) and (2,-5) is parallel to the line with given equation 2x-3y=12 find the value of a

Answers

Parallel lines have the same slope, thus, using the equation of the parallel line, we can find out the slope of the line that passes through the given points.

To find the slope of a line given its equation, we have to put the equation into the slope-intercept form, whcih we can do by solving the equation for y:

[tex]\begin{gathered} 2x-3y=12 \\ -3y=-2x+12 \\ y=\frac{-2}{-3}x+\frac{12}{-3} \\ y=\frac{2}{3}x-4 \end{gathered}[/tex]

The slope of the line is the coefficient multiplying x, which is 2/3 in this case.

So, let's name the slope m:

[tex]m=\frac{2}{3}[/tex]

Since the lines are parallel, both have the same slope m.

Also, if we want to find the slope given two numbers on the line, we can use the following equation:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, we have the points (a, 4) and (2, -5) and we have the slope m = 2/3. Substituting these, we have:

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1}_{} \\ \frac{2}{3}=\frac{-5-4}{2-a} \\ \frac{2}{3}=\frac{-9}{2-a} \\ 2(2-a)=3\cdot(-9) \\ 4-2a=-27 \\ -2a=-27-4 \\ -2a=-31 \\ a=\frac{31}{2} \end{gathered}[/tex]

Thus, the value of a is 31/2.

Which element ,cesium or francium easily loses electron ? Justify your answer in terms of atomic size and attraction towards the positive nucleus Consider a father pushing a child on a playground merry-go-round. The system has a moment of inertia of 84.4 kg m2. The father exerts a force on themerry-go-round perpendicular to its radius to achieve an angular acceleration of 4.44 rad/s2.(a) How long (in s) does it take the father to give the merry-go-round an angular velocity of 2.29 rad/s? (Assume the merry-go-round is initially atrest.)S(b) How many revolutions must he go through to generate this velocity?revolutions(C) If he exerts a slowing force of 270 N at a radius of 1.25 m, how long (in s) would it take him to stop them?s What can you infer about the freedom riders journey? can anyone help me with this question What change should be made in the sentence below?
