Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude
is given by the equation:
Temperature in
= 
Given that, the altitude,
= 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in
= 
And value of altitude,
= 5,000 feet
Let us put the value of
in the equation and let us find the value of temperature in
.
Temperature in
=

Therefore, the answer is:
A) -10°F
Answer: D opposite angles in all quadrilateral are congruent true
Here is the correct format for the question
At 2:00 PM a car's speedometer reads 30 mi/h. At 2:15 PM it reads 50 mi/h. Show that at some time between 2:00 and 2:15 the acceleration is exactly 80 mi/h².Let v(f) be the velocity of the car t hours after 2:00 PM.Then
. By the Mean Value Theorem, there is a number c such that 0 < c <
with v'(c) =
. Since v'(t) is the acceleration at time t, the acceleration c hours after 2:00 PM is exactly 80 mi/h^2.
Answer:
Step-by-step explanation:
From the information given :
At 2:00 PM ;
a car's speedometer v(0) = 30 mi/h
At 2:15 PM;
a car's speedometer v(1/4) = 50 mi/h
Given that:
v(f) should be the velocity of the car t hours after 2:00 PM
Then
will be:


= 20 × 4/1
= 80 mi/h²
By the Mean value theorem; there is a number c such that :
with 
Answer:
12
Step-by-step explanation:
(13-x)=1
13-x-13=1-13
-x=-12
Divide both sides by -1
