Line AB intersects line CD at point F, with a ray FE forming a right angle EFB. What angle relationship best describes angles AF

vova2212 [387]

Based on the positions of angles AFC and EFC, the relationship between them is a Complimentary angle.

<h3>How are AFC and EFC related?</h3>

Angles AFC and EFC are complimentary angles because complimentary angles are angles that add up to 90 degrees.

Looking at the shape, Line FC divides the right angle to create angles AFC and EFC so when these are added together, they equal 90 degrees.

In conclusion, angles AFC and EFC are complimentary.

What is the fourth term in the binomial expansion of (2x – y) 7?

nata0808 [166]

Answer:

$(7C4) (2x)^4 (-y)^{7-4}$

And replacing we got:

$35 (2^4) x^4 (-y)^{-3}$

And then the final term would be:

$-560 x^4 y^3$

Step-by-step explanation:

For this case we have the following expression:

$(2x-y)^7$

And we can use the binomial theorem given by:

$(x+y)^n =\sum_{k=0}^n (nCk) x^k y^{n-k}$

And for this case we want to find the fourth term and using the formula we have:

$(7C4) (2x)^4 (-y)^{7-4}$

And replacing we got:

$35 (2^4) x^4 (-y)^{-3}$

And then the final term would be:

$-560 x^4 y^3$

To solve this problem you must follow the proccedure shown below:

1. Amount of lemonade in pints:

1 <span>quart of water=2 pints
1 pint of lemon
(9 ounces of honey)(0.0625 pints/1 ounce)=0.56 pints

Total in pints=2 pints+1 pint+0.56 pints
Total in pints=3.56 pints

2. </span>Amount of lemonade in<span> cups:

Total in cups=(3.56 pints)(2 cups/1 pint)
Total in cups=7.12 cups

3. </span>Amount of lemonade in<span> ounces:

Total in ounces=(7.12 cups)(8 ounces/1 cup)
Total in ounces=56.96 ounces</span>
