Answer:
Step-by-step explanation:
Plug in x = 2
g(2) = 3(2)² - 2*2 + 5
= 3* 4 - 4 + 5
= 12 - 4 + 5
= 8 + 5
= 13
Answer: The Answer is
48 over 48+36
Step-by-step explanation:
Let me draw this triangle for you as you haven't drawn the triangle.
To find the side SR , you have shown that
ΔPST ~(is similar to)ΔPRQ [AA]
As, you know when triangles are similar their sides are proportional.
So,
You can solve this question using other way also
As, ST║RQ
then ⇒ [ if in a triangle a line is parallel to a side
intersecting the other two sides in distinct points then the ratio of the segments where the line segment intersects the other two sides are same.]
So, 0.5^5 is 0.03125
multiply that by 125 and get your answer.
*3.90625* (4)
just saying, I got the 0.5^5 thing because 5 is the number of half-lives (x) and 0.5 is the rate of loss (or whatever its called).
If it were to gain, you would put 1.5
