The answer is c, y = 2 cos 4e
Step-by-step explanation:
To find how many degrees the temperature would have to rise you need to do 11 - (-7) which is equal to 18. So the temperature rose 18 degrees.
To convert Celsius to Fahrenheit you need to do
(C * 9/5) + 32. In this case it would be (11 * 9/5) + 32 which results in 51.8 degrees Fahrenheit.
Answer: A, D, & E
Step-by-step explanation:
they are all correct when 5 is plugged in.
Answer:
is the required form.
Step-by-step explanation:
If we are asked to factor the expression given, we have to first find the common term, and then apply the middle term split method if required. There are cases, where the common terms are found by grouping the like terms.
Now the expression that is given here is:
![294w^2\:-\:150](https://tex.z-dn.net/?f=294w%5E2%5C%3A-%5C%3A150)
So here we will take 6 common and we will get:
![294w^2\:-\:150\\=6\left(49w^2-25\right)](https://tex.z-dn.net/?f=294w%5E2%5C%3A-%5C%3A150%5C%5C%3D6%5Cleft%2849w%5E2-25%5Cright%29)
Now we will use the formula:
![x^2-y^2=\left(x+y\right)\left(x-y\right)](https://tex.z-dn.net/?f=x%5E2-y%5E2%3D%5Cleft%28x%2By%5Cright%29%5Cleft%28x-y%5Cright%29)
and we get:
![6\left(49w^2-25\right)\\=6\left(7w+5\right)\left(7w-5\right)](https://tex.z-dn.net/?f=6%5Cleft%2849w%5E2-25%5Cright%29%5C%5C%3D6%5Cleft%287w%2B5%5Cright%29%5Cleft%287w-5%5Cright%29)
Hence, this is the required factor form of the given expression.
