Answer: The bar graph could work.




ZanzabumX [31]3 years ago

Answer:

Step-by-step explanation: A box plot takes a large amount of data and clearly identifies the median, first quartile, and third quartile. The first quartile identifies the 25th percentile, and the third quartile identifies the 75th percentile.

To determine how the height of the student compares to 25% of his class, the value of the first quartile of the heights is needed.

Therefore, the best graph type to show how the student compares to 25% of his class is a box plot.

Prove that sinA-sin3A+sin5A-sin7A/cosA-cos3A-cos5A+cos7A= cot2A
MAVERICK [17]
Write the left side of the given expression as N/D, where
N = sinA - sin3A + sin5A - sin7A
D = cosA - cos3A - cos5A + cos7A
Therefore we want to show that N/D = cot2A.

We shall use these identities:
sin x - sin y = 2cos((x+y)/2)*sin((x-y)/2)
cos x - cos y = -2sin((x+y)/2)*sin((x-y)2)

N = -(sin7A - sinA) + sin5A - sin3A
    = -2cos4A*sin3A + 2cos4A*sinA
    = 2cos4A(sinA - sin3A)
    = 2cos4A*2cos(2A)sin(-A)
    = -4cos4A*cos2A*sinA

D = cos7A + cosA - (cos5A + cos3A)
   = 2cos4A*cos3A - 2cos4A*cosA
   = 2cos4A(cos3A - cosA)
   = 2cos4A*(-2)sin2A*sinA
   = -4cos4A*sin2A*sinA

Therefore
N/D = [-4cos4A*cos2A*sinA]/[-4cos4A*sin2A*sinA]
       = cos2A/sin2A
      = cot2A

This verifies the identity.

Compound Interest Rate Formula: \displaystyle A = P(1 + \frac{r}{n})^{nt}

  • A is final amount
  • P is principle amount
  • r is rate
  • n is compound rate
  • t is time (in years)

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

P = $1900

r = 3% = 0.03

n = 4

<u>Step 2: Solve for </u><em><u>A</u></em>

  1. Substitute [CIRF]:                    \displaystyle A = 1900(1 + \frac{0.03}{4})^{4(6)}
  2. (Parenthesis) Divide:              \displaystyle A = 1900(1 + 0.0075)^{4(6)}
  3. (Parenthesis) Add:                  \displaystyle A = 1900(1.0075)^{4(6)}
  4. (Exponents) Multiply:             \displaystyle A = 1900(1.0075)^{24}
  5. Exponents:                             \displaystyle A = 1900(1.19641)
  6. Multiply:                                  \displaystyle A = 2273.19
