Answer:
Step-by-step explanation:
divide that triangle into two right triangles. you can get the two sides of each triangle by taking the radi of the two circles that they're connected too and then subtract the radi of the 3 length circle and the 4 length circle from 6. then you perform the right triangle formula on each right triangle the add it together.
Answer:
-----> vertex form
-----> standard form
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
substitute the values and solve for a
the equation in vertex form is equal to
Find the equation of the parabola in standard form
we know that
the equation of the parabola in standard form is equal to
we have
convert to standard form
Multiply num and dem by 2 each to get 8/20
Given:2009 : 3,500 populationdecrease of 2.2% per year. 100% - 2.2% = 97.8%
2014 - 2009 = 5 years
3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57
The bird population in 2014 will be 3,131.57 or 3,132. add me as da brainliest
Step-by-step explanation:
-13 - 23 = -13 + (-23)
= -36
-13 - (-23) = -13 + 23
= 10
