2+cotA=1 homework help

Mathematics
1 answer:
Alex Ar [27]3 years ago
3 0
2+\cot A=1\implies \cot A=-1\implies \tan A=-1

This happens whenever A=\dfrac{3\pi}4 or A=\dfrac{7\pi}4. More generally, \tan A=-1 whenever you start with one of these angles and add any multiple of \pi, so the general solution would be A=\dfrac{3\pi}4+n\pi, where n is any integer. (Notice that when n=1, you end up with \dfrac{7\pi}4.)

I need help! This pattern repeats every 4 terms. The pattern is square, hexagon, trapezoid, triangle. What is the shape in the 7
alina1380 [7]
<h3>Answer:  Trapezoid</h3>

==========================================================

Explanation:

There are two ways to do this problem.

Method 1 involves listing out the terms until we reach the seventh one.

  1. square
  2. hexagon
  3. trapezoid
  4. triangle
  5. square
  6. hexagon
  7. trapezoid
  8. triangle

We see that the trapezoid is term 7.

-------------

Method 2 is faster and the one I recommend.

Since the pattern repeats every 4 items, this means we divide by 4 and look at the remainder. Ignore the quotient entirely.

7/4 = 1 remainder 3

The remainder 3 means that the answer is found in term 3, which is the trapezoid.

What is the product of 7.5 and 1,000
slega [8]
1,000 multiplied by 7.5. What you need to do is add three zeros to 7.5 so you move the decimal back 3 times. 7.5 will now be 7,500.  Hope I helped!!!
