The acceleration of the snail at time t=5 minutes can be found by taking the derivative of the velocity function v(t) with respect to time t. When the ant catches up to the snail at time t = 15, their displacements are equal, so we have s(15) - s(12) = v_ant(12)(15-12).
(a) The acceleration of the snail at time t=5 minutes can be found by taking the derivative of the velocity function v(t) with respect to time t. Thus, we have a(t) = v'(t) = 1.4/(1+e^(1.4t))^2 * 1.4 = 1.96/(1+e^(1.4t))^2 evaluated at t=5. Plugging in t=5, we get a(5) = 0.0935 inches per minute per minute.
(b) The displacement of the snail over the interval 0 <= t <= 15 minutes can be found by integrating the velocity function v(t) with respect to time t. Thus, we have s(t) = ∫v(t)dt = 1.4ln(1+e^(1.4t)) evaluated from t=0 to t=15. Plugging in these values, we get s(15) - s(0) = 9.335 inches.
(c) To find the time t when the snail's instantaneous velocity equals its average velocity over the interval 0 <= t <= 15 minutes, we need to solve the equation v(t) = (s(15)-s(0))/15. Substituting the expressions for v(t) and s(t), we get 1.4ln(1+e^(1.4t)) = 0.6223t + 0.6223. This equation cannot be solved analytically, so we can use numerical methods to approximate the solution.
(d) Since the snail and ant are traveling in the same direction, the displacement of the ant over the interval 12 <= t <= 15 minutes is equal to the displacement of the snail over the same interval. Thus, we can use the same formula for s(t) as in part (b). We know that the ant has a constant acceleration of 2 inches per minute per minute, so its velocity at time t = 12 is given by v_ant(12) = B + 2(12-12) = B. When the ant catches up to the snail at time t = 15, their displacements are equal, so we have s(15) - s(12) = v_ant(12)(15-12). Substituting the expressions for s(t) and v_ant(12), we get 1.4ln(1+e^(1.415)) - 1.4ln(1+e^(1.412)) = 3B. Solving for B, we get B = (1.4ln(1+e^(21))-1.4ln(1+e^(16)))/3.

The Hiking Club is on a trip to hike up a mountain. The members increased their elevation 290 feet during their hike
this morning. Now they are at an elevation of 450 feet.
a. Explain how to find their elevation before the hike.
b. Han says the equation e + 290 = 450 describes the situation.
What does the variable e represent?
C. Han says that he can rewrite his equation as
e = 450 + -290 to solve for e. Compare Han's strategy to your
strategy for finding the beginning elevation.
Answer:
Step-by-step explanation:
A. Subtract 290 from 450, 450-290= 160
B. The variable e represents the elevation before they started the hike
C. 450+-290= 450-290
The requried elevation before the hike is given as 160 feet and the required equation model of the situation is e + 290 = 450 where e represents the elevation before the hike.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
a. To find the members' elevation before the hike, we can subtract the increase in elevation from their current elevation. So, their elevation before the hike would be 450 - 290 = 160 feet.
b. In the equation e + 290 = 450, the variable "e" represents the members' elevation before the hike.
c. Han's strategy for finding the beginning elevation involves adding -290 to both sides of the equation e + 290 = 450 to get e = 450 + -290. This is equivalent to subtracting 290 from both sides of the equation e + 290 = 450. Both strategies result in the same equation, e = 160, which tells us that the members' elevation before the hike was 160 feet.

Huey is reading a book that is 697 pages long.
He tells a friend that he is about 3/4 of the way done.
About how many more pages must Huey read before he finishes the book?
Answer:
700 books huey finish he your answer
Answer:
175 pages
Step-by-step explanation:
Answer:
. 175
Step-by-step explanation:
There are 2 ways that we can find the answer to this question:
1. Take 1/4 of 697
2. Take 3/4 of 697 and minus the product from 697.
Let's do it both ways:
If we are doing it the first way it would look like this:
(1/4)(697) = 175
Note that we get 1/4 because Huey already read 3/4 of the book so he has 1/4 left.
The second way would look like this:
(3/4)(697) = 523
679 - 523 = 174 (roughly 175)
Therefore, the answer to your question would be . 175. pls mark brainliest
How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?
Answer:
186.7 cubes
Step-by-step explanation:
How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?
Step 1
We find the volume of the box
= Length × Width × Height
Length = 3 1/3 inches = 10/3 inches
Width = 2 2/3 inches = 8/3 inches
Height = 2 1/3 inches = 7/3 inches
The volume of the box =
10/3 inches × 8/3 inches × 7/3 inches
= 560/9 cubic Inches
= 62 2/9 cubic inches
Step 2
How many 1/3 inch cubes would fill the box.
This is calculated as:= 62 2/9 cubic inches/ 1/3 inches
= 560/9 ÷ 1/3
= 560/9 × 3/1
= 186.66666667 cubes
Approximately = 186.7 cubes
Write an explicit and recursive rule for the geometric sequence -5, 10, -20, 40… and use it to find the 12th
Answer:
See solutions below
Step-by-step explanation:
Given the sequence -5, 10, -20, 40...
The nth term of the GP is expressed as;
Tn = ar^n-1
a is the first term
r is the common ratio
n is the number of terms
From the sequence, a = -5
r = 10/-5 = -20/10 = -2
Substitute
Tn = -5(-2)^n-1
This gives the explicit formula
For recursive;
a1 = -5
a2 = 10 = -2(-5) = -2a1
a3 = -20 = -2(10) = -2a2
From the shown sequence, we can see that;
an = -2an-1
This gives the recursive formula
Get the 12th term;
Using the explicit formula
T12 = -5(-2)^12-1
T12 = -5(-2)^11
T12 = -5(-2048)
T12 = 10240
Hence the 12th term is 10240

A object falls at 16t^2 feet in t seconds you drop a rock from a bridge that is 906 what is the hight in feet after the rock is droped
Answer:
824 feet
Step-by-step explanation:
Given
[tex]h(t) = 16t^2[/tex]
[tex]H = 906[/tex] -- Initial Height
Required
Calculate the height after 2 seconds --- missing from the question
First, we calculate the distance moved in 2 seconds
[tex]h(t) = 16t^2[/tex]
[tex]h(2) = 16*2^2[/tex]
[tex]h(2) = 16*4[/tex]
[tex]h(2) = 64[/tex]
This means that the object covered 64feet
The object current height is then calculated as:
[tex]Height = H - h(t)[/tex]
t = 2. So, the equation becomes
[tex]Height = H - h(2)[/tex]
Substitute values for H and h(2)
[tex]Height = 906- 64[/tex]
[tex]Height = 824[/tex]

Answer:
In general , While estimating a bodies temperature that temperature is not the same for long, the temperature of the body is not at homeostasis, the temperature constantly has bumps and drops in the temperature this causes in accuracy thats why the thermometer takes 10-20 seconds because it takes the average of all the temperature's so it is accurate, that is a difficulty when estimating temperature because estimates are not good and the temperature keeps having ups and downs.
