Question 14:
We are given that:
C = πd
To solve for d, we need to isolate the d on one side of the equation. This means that we need to get rid of the π next to the d.
In order to do so, we can simply divide both sides of the equation by π as follows:
C/π = πd/π
d = C/π .........> The first option
Question (15):
We are given that:
d = rt
To solve for r, we need to isolate the r on one side of the equation. This means that we need to get rid of the t next to the r.
In order to do so, we can simply divide both sides of the equation by t as follows:
d/t = rt/t
r = d/t.........> The third option
Hope this helps :)
Answer:
The answer is C
Step-by-step explanation:
Answer: y= (x+2)² −
5
Step-by-step explanation:
The way I got this answer is by completing the square. The first step though, when looking at this equation, is to see if we can factor it. The way to check is to look at the coefficient for x² which is 1, and the constant, in this case -1. If we multiply those together, we get −. Now we look at the middle term, 4x. We need to find any numbers that multiply to equal − 1x² and add to 4x. There aren't any, which means it is not factorable.
Hope I helped
