Using the information given and linear function concepts, it is found that:
- a) The equation is:
.
- b) The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.
- c) It takes 200 seconds for the skydiver to reach the ground.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when t changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
Item a:
- The skydiver descends at a rate of 25 feet per second, hence
.
Then:
<u>90 seconds after the parachute opens, his altitude is 2750 feet</u>, which means that when 
, which is used to find b. Then:
Hence, the equation is:
.
Item b:
Time is in seconds, hence, this is y(120).
The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.
Item c:
The time it takes to reach the ground is t for which y(t) = 0, hence:
It takes 200 seconds for the skydiver to reach the ground.

Change the information into an equation and do sequence. pull out any necessary information.
y = 2x + 1
starts at 1... so your first sequence is 1.
plug in x=1 then it becomes 3. then the next sequence you plug in 3 (, the answer to your previous solve) you get 7. continue to do this. next sequence you plug in x=7 into the equation y = 2x + 1.
thus, y = 2(7) + 1 =15... so forth...
therefore the answer is B.
Hope this helps :)
Answer:
(100°)
Step-by-step explanation:
first join point 162° to 98° to form a triangle
then add
162°+98°
=260°
an angle totally has 360°
so you minus 260° from 360°
360°-260°
=100°
(sorry,thanks and hope I helped)
Answer:
Slope intercept form:
y = 2x + 5
Step-by-step explanation:
m = 2; (-3 , -1)
Slope point form : y - y1 = m(x - x1)
y - [-1] = 2(x - [-3])
y + 1 = 2(x + 3)
y + 1 =2x + 3*2
y + 1 = 2x + 6
y = 2x + 6 - 1
y = 2x + 5 This is in slope intercept form y =mx + b
The last one. People per hour because the dependent quantity is the people.
