The answer to this is 30.41 due to the zero the answer cannot be moved on so it will stay the same.
B because the 2 is in the hundredths place and then you look behind the 2 which is a 5.
If its five or more you go up and 4 or less you go down, which means that you add one to the 2 which is 3 and you get rid of anything behind the 3 that was the originally.
Answer:
11
Step-by-step explanation:
f(1) = 3(1) + 8 = 3 + 8 = 11
We can find the answer by dividing the world population by the area of NYC in square feet.
There is 27,878,400 sq ft in a mile because 5280^2 is that value. So that means
7400000000 people in 27,878,400 sq ft. You can divide that into sqft/person which is 0.00376 sqft/person. Now multiply that by 305. you will get 1.149 sq/person in NYC.
Hope this helps!
ps that was a crazy problem
Answer:
Below in bold letters.
Step-by-step explanation:
a. y = 3x - 1.
The equation of the perpendicular line will have slope -1/ 3.
So we have the equation y - y1 = -1/3(x - x1) where (x1, y1) is a point on this perpendicular line.
As the line passes through (0,0):
y - 0 = 1/3(x - 0)
y = -1/3x is the required equation.
If x,4 is on the line then x is found by substituting for y:
4 = -1/3 x
x = 4 / -1/3
x = 4*-3 = -12.
b. y = 1/4x + 2
By the same method as in part a:
the equation is y = -4x.
x = 4 / -4 = -1.
