Answer:
Option 2 and 5 are correct.
Step-by-step explanation:
We need to tell which one of them is quadratic function.
Option 1 is exponential decay so, it is not quadratic.
Option 2 is quadratic because the diver will take the parabolic shape when jumps.
Option 3 is not quadratic.Option 4 is not quadratic it is linear.
Option 4 is again exponential not quadratic.
Option 5 is quadratic because it takes the parabolic shape again.
Answer:
v = 17.4 meters
Step-by-step explanation:
This is a triangle with height (red dotted line) given.
The area of a triangle is given by the formula:
Where
A is the area
b is the base length
h is the height
Given height = 12, and
area = 104.4
THe base is labeled as "v", so we find v by replacing into formula:
The base, v, is 17.4 meters
Answer:
Step-by-step explanation:
$ 4 per ride and 0.75 per mile
y = 0.75x + 4.....with x being # of miles and y being total cost
if a person only had $ 20....so sub in 20 for y and solve for x
20 = 0.75x + 4
20 - 4 = 0.75x
16 = 0.75x
16 / 0.75 = x
x = 21.33 (or 21 1/3) miles <=====
