Solve [0, 2pi)
3 Cos(2x) = 5 Sin(x) - 1

Answers

Given :

Solve [0, 2π)

3cos(2x) = 5sin(x) - 1

To Find :

The value of x in range [0,2π).

Solution :

We know, cos(2x) = 1 - sin²x .

3( 1 - 2sin²x ) = 5sinx - 1

3 - 6sin²x = 5sinx - 1

6sin²x + 5sinx - 4 = 0

6sin²x + 8sinx - 3sinx - 4 = 0

2sinx( 3sinx + 4 ) - 1( 3sinx + 4) = 0

sin x = 1/2 and sin x = -4/3 .

Since, sin x ≤ 1.

So, sin x = 1/2 .

x = π/6 .

Therefore, value of x is π/6.

Hence, this is the required solution.

State the Angle Relationship & Find the measure of the indicated angle that makes lines u and v parallel.

Answers

Answer:

the indicated angle should be 121°

Step-by-step explanation:

If 2 lines are parallel to each other & a transversal intersects both of them , the corresponding angles on a same side are equal.

If the indicated angle will be equal to the given angle , they will be known as corresponding angles only when v || u.

So the indicated angle is 121°

Andre rode his bike at a constant speed. He rode 1 mile in 5 minutes.
Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
A - T = 5d
B - T = 1/5 d
C - T = d+4
D - T = d-4

Answers

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that Andre rode his bike at a constant speed.

Number of miles driven = 1 mile

Time taken to drive 1 mile = 5 minutes.

Then speed can be calculated using formula:

Speed = Distance / Time

Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.

Speed = Distance / Time

Time = Distance / Speed

Plug the given values

t = 5d

Hence find answer will be equation t=5d.

A company sells shares in their stock for a certain price. On one sunday the price of the company's stock was $37.84 per share. This price of the stocks per share changes each day. By how much dos the price of the stock per share change from Sunday until the end of Friday? What is the price of the company's stock per share at the end of the day on Thursday?

Answers

Hi, you've asked an incomplete question. However, I assumed that the price of the stock at the end of Thursday is $43, Friday is $46.

Answer:

about +21.56% (or $8.16) by Friday

$43

Step-by-step explanation:

What we simply need to do is to note the percentage difference in price between Sunday and Friday. By subtracting the difference price we get,

$46- $37.84 = $8.16 To percentage

[tex]\frac{8.16}{37.84} *100=[/tex] 21.56%.

It is obvious from the data presented that the price of the company's stock per share at the end of the day on Thursday is $43.

7. What are the x-intercepts of the graph of y = (3x +8)(5x - 3)(x - 1)?

Answers

Answer:

y = 15x^3 + 16x^2 - 55x + 24

Step-by-step explanation:

y = (3x +8)(5x - 3)(x - 1)

y = (15x^2 - 9x + 40x -24) * (x - 1)

y = (15x^2 + 31x - 24) * (x-1)

y = 15x^3 - 15x^2 + 31x^2 - 31x - 24x + 24

The x-intercepts of a graph are the points where the graph crosses the x-axis.

The x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]

The function is given as:

[tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]

First, we plot the graph of [tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]

See attachment for the graph

Next, write out the x-values when the graph crosses the x-axis.

From the graph, we have:

[tex]\mathbf{x = -\frac 83}[/tex]

[tex]\mathbf{x = \frac 35}[/tex]

[tex]\mathbf{x = 1}[/tex]

Hence, the x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]

The reserve ratio is 20 percent. Households deposit $5000 in currency into the bank and that currency is added to reserves. Recall, to calculate checkable deposits you have to add the original checkable deposits to the new deposit. To calculate required reserves for the deposits, you have to multiply the required reserve ratio (decimal from) by checkable deposits. To calculate excess reserves, you will subtract required reserves from actual reserves.2.1. What level of excess reserves does the bank now have? 2.2. Complete the table below for the Third National Bank. You have to distinguish between a bank's assets and bank's liabilities. The figures in the table below are for the Third National Bank.

Explain the basics of this banks balance sheet. 2.4.If the required reserve ratio for the Third National Bank is 10 percent, what is the monetary multiplier? (helpful stuff)Recall, to calculate you have to use the formula: Monetary Multiplier = 1Required Reserve Ratio. The money multiplier is a key measure in banking that helps to predict the money supply that will be available to drive economic growth. As you can see from the formula, if the reserve requirement is 20%, the money multiplier will be 1 divided by 0.2, which is 5. We can then use the money multiplier multiplied by the excess reserves to determine the maximum checkable-deposit creation that will be provided by the new money entering the system.2.5. If the monetary multiplier is 4, what is the required reserve ratio? Describe how and identify by what amount the Third National Bank can create money in the economy. (helpful stuff)Recall that, generally, bank creates money in a typical economy by making loans.
