Help with number 6 please. thank you.​

See Below.

Step-by-step explanation:

We are given that:

And we want to show that:

From the original equation, divide both sides by (T - T₀) and multiply both sides by dt. Hence:

Take the integral of both sides:

Integrate. For the left integral, we can use u-substitution. Note that T₀ is simply a constant. Hence:

Raise both sides to e:

Simplify:

Since the temperature T will always be greater than or equal to the surrounding medium T₀, we can remove the absolute value. Hence:

Therefore:

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
