Mr. Chang wants to retire in 10 years. He deposits $650.00 every three months into his retirement investment account. If the acc
Fittoniya [83]

Answer:

Mr. Chang will have 15714.90 dollars.

Step-by-step explanation:

p = 650

r = 7.8/4/100=0.0195

Number of periods or n = 5\times4=20

Future value formula is : p[\frac{(1+r)^{n}-1}{r} ]

Putting the values in formula we get;

650[\frac{(1+0.0195)^{20}-1}{0.0195} ]

= $15714.90

Hence, Mr. Chang will have 15714.90 dollars.

Prove that \displaystyle \frac{\cos \theta}{1 + \sin \theta} = \frac{1 - \sin \theta}{\cos \theta}
Bogdan [553]

Answer:

sin^2(θ)+cos^2(θ)=1

Step-by-step explanation:

We know that the statement above is true because of the Pythagorean identity theorem, which states the aforementioned equation. If you solve the equation for 1 you get the same equation.

To do this first multiply both sides by cos(θ), this gives you (cos^2θ)/1+sinθ = 1-sinθ

Then, multiply both sides by sinθ. This equals cos^θ=1-sin^2θ.

Finally, add sin^2θ to both sides. This equals the final answer of cos^2θ+sin^2θ=1. Which is true.

Two fair dice are tossed, and the up face on each die is recorded. Find the probability of observing each of the following event
Kamila [148]

Answer:

Step-by-step explanation:

When two fair dice are tossed sample space consists of 36 events

(1,1)....(6,6)

A_ The difference of numbers is 2 or less

Favorable outcomes = (1,1) (1,2) (1,3) (2,1) (2,2)(2,3) (2,4) (3,1) (3,2) (3,3) (3,4) (3,5) (4,2) (4,3)(4,5) (4,6) (5,3) (5,4) (5,6)\\

Hence Probability = \frac{19}{36}

B) A 4 does not appear on either die

Then we must not have these

(4,1)(4,2)(4,3) (4,4) (4,5) (4,6)\\(1,4) (2,4) (3,4) (5,4) (6,4)

Hence probability = \frac{36-11}{36} =\frac{25}{36}

C:  The sum of numbers is 10 or more:

FAvourable outcomes are:

(4,6) (5,5) (5,6) (6,5) (6,4)

Probability = \frac{5}{36}
