Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 =7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Answer: 24.63
Step-by-step explanation: To find the area of a circle you square the radius (by 2) and then multiply it by pie.
Answer:
yes to both
Step-by-step explanation:
For a relationship to be a function then each value of x must relate to exactly one unique value of y.
This is the case in this table as
2 → 76
4 → 152
6 → 228
All unique values thus a function
To determine if it is linear then the rate of change is constant for each set of ordered pairs. This is measured using the slope formula.
m = 
with (x₁, y₁ ) = (2, 76) and (x₂, y₂ ) = (4, 152 ) ← ordered pair from table
m =
=
= 38
Repeat with (x₁, y₁ ) = (4, 152) and (x₂, y₂ ) = (6, 228)
m =
=
= 38
Since rate of change is constant then function is linear
Answer:
16 fl oz
Step-by-step explanation:
1 cup of H2O is 8 fluid ounces
So, if we have 2 cups, we multiply 8 by 2 to get 16 fl oz.
