Answer:

\frac{3}{10}

Step-by-step explanation:

  • Set up the fraction 27/90
  • The numerator (the number above the fraction sign) represents the number of questions Jordan got correct.
  • The denominator (the number below the fraction sign) represents the number of questions on the test.
  • To simplify this equation, divide the numerator and denominator by their Greatest Common Factor (GCF) or continue dividing the numerator and denominator by the same number
  • GCF Method: GCF = 9 so 27/9 = 3 and 90/9 = 10
  • Therefore, the fraction is 3/10
  • Other Method: You know that 27 and 90 can be divided by 3, so divide both numbers by 3. 27/3 = 9 and 90/3 = 30.
  • 9 and 30 can also be divided by 3. 9/3 = 3 and 30/3 = 10.
  • Therefore, the fraction is 3/10

Answer:

  • <u>The rate of return is 8.15%</u>
  • <u>This is a good investment</u>

<u></u>

Explanation:

For the first question, you need to find the rate that makes the present value of a stream of ten constant annual payments of $15,000 equal to the $100,000 investment.

The formula that returns the present value of a constant payment is called the annuity formula and is:

      Present\text{ }value=payment\times \bigg[\dfrac{1}{r}-\dfrac{1}{r(1+r)^t}\bigg]

In your problem you know:

  • Present value: $100,000
  • payment: $15,000
  • r: ?
  • t: 10

You cannot solve for r directly. You must guess a value and calculate the right side of the equation until to you find the rate that makes it equal to 100,000.

Try 5%:

       \$15,000\times \bigg[\dfrac{1}{0.05}-\dfrac{1}{0.05(1+0.05)^{10}}\bigg]=\$115,826

Then, the rate of return is greater than 5%. After several trials you will find that the rate of return is 8.15%.

Since this rate is higher than 8%, which is what the company requires, this is a good investment.

Can u guys please help me!!
Alona [7]

Answer and Step-by-step explanation:

This problem requires the use of trigonometric functions, specifically the tangent trig function.

tan(Angle)=\frac{opposite}{adjacent}

Plug in the values.

tan(40) = \frac{8000}{x}

Multiply by x to both sides, then divide by tan(40) to both sides.

x = \frac{8000}{tan(40)}

Now, plug this into a calculator and rounded to the nearest whole number (foot).

x = 9534.0287

x = 9534 ft.

The answer is 9534 ft., the last option.

Which trigonometric functions are negative in the fourth (IV) quadrant?
anzhelika [568]
<h3>Answers are: sine, tangent, cosecant, cotangent</h3>

Explanation:

On the unit circle we have some point (x,y) such that x = cos(theta) and y = sin(theta). The sine corresponds to the y coordinate of the point on the circle. Quadrant IV is below the x axis which explains why sine is negative here, since y < 0 here.

Since sine is negative, so is cosecant as this is the reciprocal of sine

csc = 1/sin

In quadrant IV, cosine is positive as x > 0 here. So the ratio tan = sin/cos is going to be negative. We have a negative over a positive when we divide.

Because tangent is negative, so is cotangent.

The only positive functions in Q4 are cosine and secant, which is because sec = 1/cos.
