in complete sentences, explain the process in which this equation would be solved. “Mr Crenshaw can grade one set of papers in 1
hammer [34]

Answer:

6 minutes

Step-by-step explanation:

Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.

If they work together, they will be checking at a combined rate of:

1/10 + 1/15 = [3(1) + 2(1)]/30

= 5/30 = 1/6

Their combined rate is 1/6 which means they check one set in 6 minutes

Explain why the "+ C" is not needed in the antiderivative when evaluating a definite integral.
Aliun [14]

The reason the "+ C" is not needed in the antiderivative when evaluating a definite integral is; The C's cancel each other out as desired.

<h3>How to represent Integrals?</h3>

Let us say we want to estimate the definite integral;

I = \int\limits^a_b {f'(x)} \, dx

Now, for any C, f(x) + C is an antiderivative of f′(x).

From fundamental theorem of Calculus, we can say that;

I = \int\limits^a_b {f'(x)} \, dx  = \phi(a) - \phi(b)

where Ф(x) is any antiderivative of f'(x). Thus, Ф(x) = f(x) + C would not work because the C's will cancel each other.
