-24
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
Given,
f(x) = -x² + 4x - 1 and x = 0
Putting the value of x we get,
f(0)= + (4 X 0) - 1
= -0+0-1
=-1
∴f(x)= -1
So, the required value is -1
Answer:
69
Step-by-step explanation:
as , 77+x = 146(external angle) , so x = 146 - 77
so x = 69
It’s going to be 180-29 which is like 151 degrees. So it’s D
Answer:
And solving for the radius we got:
And replacing the data given we got:
And this value converted to meters is
Step-by-step explanation:
For this case we know the population size and we also know the population density
We can assume that the area is a circle. We also know that the formula for the population density is given by:
Where P represent the number of people and A the area. Since we are assuming a circle then the area is given by:
With X the radius of the circle
And then the populationd density become:
And solving for the radius we got:
And replacing the data given we got:
And this value converted to meters is
