If a thermometer indicates 40 degrees Celsius, what is the temperature in degrees Fahrenheit?
2 answers:
Answer:
Option B is correct.
Temperature in degree Fahrenheit is,
Step-by-step explanation:
We will use the temperature conversion formula from to
as follows:
where
F is the Fahrenheit in degree,
C is the Celsius in degree.
Given the statement: If a thermometer indicates 40 degrees Celsius.
⇒
Substitute this value in above formula to solve for F;
Simplify:
F = 104 degree.
therefore, the temperature in degree Fahrenheit is,

if your teacher allows the pi symbol then your answer is 2513. if your teacher requires you to use 3.14 for pi then your answer is 2512. basically you use the Pythagorean theorem to find the height, and then plug the height (24) and the radius which is half the diameter (10) into the equation to find the volume of the cone. if you have any other questions about it please ask! hope this helps:)
Given:
The equation is:
To find:
The graph of the line that contains ordered pairs that are solutions of the given equation.
Solution:
We need to find the graph of the given equation.
We have,
At , we get
So, the x-intercept of the given equation is at point (0,4).
At , we get
So, the y-intercept of the given equation is at point (4,0).
From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).
Therefore, the correct option is C.
