Answer:
D)
Step-by-step explanation:
To start, we know that the initial boiling point is 212 degrees F. For every 1 added to E, the boiling point decreases by 2. So, we havethe equation 212 - 2E or -2E + 212 = b or D).
It’s C
You would use cos for this equation
Cos(45)= x/5
5 x cos(45
And when you put that in the calculator you will get that answer C
Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
