Use the interior angles theorem for the triangles I hope my answer helped if you have any questions don't be afraid to ask <span>(o^▽^o) <3</span>
It’s B because it’s a primary source because it comes from him
Answer:
The domain is (-∞,∞)
Step-by-step explanation:
Since there's no limit to this function, the values are infinity.
Answer:
Step-by-step explanation:
To solve this problem we need to be familiar with the formula for the surface area of a cone:
We are given the length of a side and the diameter, to calculate the radius divide the diameter in half:
To calculate the height of the cone, we must use the Pythagorean Theorem:
We can treat the side length as the hypotenuse 
, the radius as the base 
, and solve for height 
. Set the expression up like this:
Now we can plug into our original formula:
Rate of change <span>a </span>rate<span> that describes how one quantity </span>changes<span> in relation to another quantity. It is also called the slope. To calculate the rate of change in temperature, we use the expression:
Rate of change = change in temperature / change in time
</span>Rate of change = -25.5 / 1.5
Rate of change = -17 °C / min
The negative sign signifies a drop in temperature per minute.
