Answer:
46
Step-by-step explanation:
With those problems if you are not given a picture is good we draw one.
Because an angle bisector forms 2 congruent angles and because is given that < XVY ≅ < YVW then
m < XVY = m < YVW
2x+7 = x+15 , subtract x and 7 from both sides to isolate the like terms
2x-x = 15-7, combine like terms
x = 8
From the picture and the given we see that
m < XVW = m < XVY + m < YVW
m < XVW = 2x+7 + x+15 , combine like terms
m < XVW = 3x + 22, substitute x for 8
m < XVW = 3*8 + 22
m < XVW = 46
Check our work:
m < XVY = 2x+7 = 2*8 +7 = 16 +7 = 23
m < YVW = x+15 = 8 +15 = 23
m < XVW = m < XVY + m < YVW = 23+23 =46
Answer:
- ![\frac{27}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B7%7D)
Step-by-step explanation:
Given
f(x) =
- ![\sqrt{x-3}](https://tex.z-dn.net/?f=%5Csqrt%7Bx-3%7D)
Evaluate f(19) by substituting x = 19 into f(x)
f(19) =
- ![\sqrt{19-3}](https://tex.z-dn.net/?f=%5Csqrt%7B19-3%7D)
=
- ![\sqrt{16}](https://tex.z-dn.net/?f=%5Csqrt%7B16%7D)
=
- 4
=
-
= - ![\frac{27}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B7%7D)
Answer:
20,158 cases
Step-by-step explanation:
Let
represent year 2010.
We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.
Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.
We can represent this information in an exponential decay function as:
![F(t)=102,390(1-0.15)^t](https://tex.z-dn.net/?f=F%28t%29%3D102%2C390%281-0.15%29%5Et)
![F(t)=102,390(0.85)^t](https://tex.z-dn.net/?f=F%28t%29%3D102%2C390%280.85%29%5Et)
To find number of cases in 2020, we will substitute
in our decay function as:
![F(10)=102,390(0.85)^{10}](https://tex.z-dn.net/?f=F%2810%29%3D102%2C390%280.85%29%5E%7B10%7D)
![F(10)=102,390(0.1968744043407227)](https://tex.z-dn.net/?f=F%2810%29%3D102%2C390%280.1968744043407227%29)
![F(10)=20,157.970260446597\approx 20,158](https://tex.z-dn.net/?f=F%2810%29%3D20%2C157.970260446597%5Capprox%2020%2C158)
Therefore, 20,158 cases will be reported in 2020.
