The answer would be A) 14 - 12i
Simplify ( 3 - 7i + 11 - 5i )
Gather like terms ( 3 + 11 ) + ( -7i - 5i )
Simplify ( 14 - 12i ).
I added a screenshot with the head of the question
Answer:sin (140°)
Explanation:Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.
Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°
Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.
Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)
Hope this helps :)
He should use pounds!
because we know that bowling balls are not light enough to use ounces or grams. And they are not heavy enough to use tons. Usually when you go to bowling alleys they have different bowling balls because they all weigh different pounds :D
i hope this makes sense lol
have a good one
merry christmas
as a fraction it would be 74 over 25 in one way there might be other ways
Use the Pythagorean theorem
<span>the hypotenuse is the ladder which is 20 ft and the base is 12 ft thus </span>
<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 144 = 400 </span>
<span>a^2 = 256 </span>
<span>a = 16 </span>
<span>so its 16 ft</span><span />
