Answer:
Segment
Step-by-step explanation:
Its only part of the line.
(5,36)(8,48)
slope = (48 - 36) / (8 - 5) = 12/3 = 4
y = mx + b
slope(m) = 4
(5,36)...x = 5 and y = 36
now sub and find b
36 = 4(5) + b
36 = 20 + b
36 - 20 = b
16 = b
equation is : y = 4x + 16.....in standard form : 4x - y = -16 <==
=======================
function notation : f(x) = 4x + 16
=======================
x axis will be ur hrs....I would label them at intervals of 1
y axis will be total cost of renting the bike......as far as the intervals...not sure how to label them.....sorry....I wanna say intervals of 2...but am not sure
y = 4x + 16
slope = 4
y int = (0,16)
x int = (-4,0)
so start at (-4,0)....and since ur slope is 4, go up 4 and to the right 1...keep doing this and u will cross the y axis at (0,16)
Answer: Ana will hit the water after 3 seconds.
Step-by-step explanation:
The exercise gives you the following function which models Anna's height above the water (in meters) after diving "x" seconds:
You can rewrite the function with 
:
In order to calculate the number of seconds Ana will hit the water after diving, the procedure is:
- Substitute 
into the function:
- Solve for "x".
By the Zero Product Property, you know that if 
, then 
or 
.
Then you get:
- Choose the positive value (
)
Then, Ana will hit the water after 3 seconds.
