Answer:
the relation is not one-to-one.
Step-by-step explanation:
it can't because every number is in the 4th quadrant.
We have that
<span>points A (-5, 6) and B (7, -1)
Part A)
find the distance
d=</span>√[(y2-y1)²+(x2-x1)²]-------> d=√[(-1-6)²+(7+5)²]----> d=√(49+144)
d=√193 units
Part B)
find the midpoint
ABx=(x1+x2)/2-----> (-5+7)/2-----> ABx=1
ABy=(y1+y2)/2-----> (-1+6)/2-----> ABy=2.5
the midpoint is (1,2.5)
Part C)
find the slope
m=(y2-y1)/(x2-x1)-----> m=(-1-6)/(7+5)--------> m=-7/12
the slope m=-7/12
Percent literally means per one hundred so you can say:
420(55/100)
23100/100
231
You could also think of it like setting up equal ratios...
55/100=n/420
n=23100/100
n=231
Answer:
Option B. 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
p-----> the number of painters
b----> the time taken to paint the building
we know that

so

Answer:
15.2 in
Step-by-step explanation:
The surface area of a sphere is given by the formula below:
Surface area of sphere= 4πr², where r is the radius
Given that the surface area is 2903.33 in²,
2903.33= 4πr²
Divide both sides by 4π:

Square root both sides:

r= 15.2 in (3 s.f.)
