Step-by-step explanation:
first ..
subtract 2 on both sides 2-2...2-y
then you should have 1/2x =y-(-2) then divide

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 :)
In probability<span> theory, the </span>law<span> (or formula) of total </span>probability<span> is a fundamental rule relating marginal </span>probabilities<span> to conditional </span>probabilities. It expresses the total probability<span> of an outcome which can be realized via several distinct events. I hope this answers your question! :)</span>
Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
The answer would be 2 and 3/10. To find this, I multiplied 1 and 1/2 by 2 and 3 and 1/2 by two. So, now to make 3 dozen muffins, a recipe uses 7 cups of flour. I did this because obviously dividing 3 and 7 are easier and its hard to find how many cups of flour make 1 dozen when you have the equation for 1 and 1/2 because 1 doesn't go into 1 and 1/2 equally. Now, with the new equation, I can just divide 3 by 3 to get 1 (which would be 1 dozen muffins) and also divide 7 by 3 to get 2.3. 2 is obviously the whole number in the mixed number and .3 is the fraction, which is 3/10. Hope this helps!
