Answer:
Step-by-step explanation:
if you consider ) to be the elevation of the ocean, and the dolphin dives 100 feet, its new elevation will be -100 ft
E40435.29 = E404,000
E214729.08 = E215,000
E64968.75 = E650,000
E223589.99 = E224,000
E111111.11 = E110,000
Hope this helps , pleeease vote as brainliest!!
Answer:
12t² - 9t - 2
Step-by-step explanation:
Combine like terms. Like terms have same variable with same exponents.
(7t² - 6t-4) + (5t² - 3t+2) = 7t² - 6t-4 + 5t² - 3t+2
= <u>7t² + 5t²</u> <u>- 6t - 3t </u> <u>- 4 + 2</u>
= 12t² - 9t - 2
Answer:
- -108.26
- -108.13
- -108.052
- -108.026
- -108
Step-by-step explanation:
A graphing calculator or spreadsheet is useful for making the repeated function evaluations required.
The average velocity on the interval [a,b] will be ...
v avg = (y(b) - y(a))/(b-a)
Here, all the intervals start at a=3, so the average velocity for the given values of t will be ...
v avg = (y(3+t) -y(3))/((3+t) -3) = (y(3+t) -y(3))/t
This can be computed for each of the t-values given. The results are shown in the attached table.
__
We note that the fractional part of the velocity gets smaller in proportion to t getting smaller. We expect it to go to 0 when t goes to 0.
The estimated instantaneous velocity is -108 ft/s.
_____
We can simplify the average velocity equation to ...
v avg = ((48(3+t) -26(t+3)^2) -(48(t+3) -26(3)^2)) / t
= (48t -26(t^2 +6t))/t
= 48 -26t -156
<em> v avg = -108 -26t</em>
Then the average velocity at t=0 is -108.
