Calculate the indefinite integral: (assume t> a and t > b. use c for the constant of integration.)
∫ t dt/ (t-a) (t - b) =

Step-by-step explanation:  

(1)

We can use partial fraction to solve this kind of integral.

In partial fraction we need to split the this fraction in two new fractions:

(2)

Now, we need to find the values of X and Y.

Let's work the right equation of (2). We can use least common denominator

Now we can use common factor in the numerator.

(3)

If we see, we can compere the (3) whit the left side of (2).

The numerators are the same, so we can compare term by term, like this:

(4)

(5)

We just need to solve the system of equations ((4) and (5)) to find X and Y.

and

Now, putting this two values in (2) and next we will take the integral.

Let's recall that the integral of (1/(x-a))dx is log(x-a), so using it we can find the integral.

I hope it helps you!

no this is a nonlinear negative

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
