What is the formula of 2AB=2AB

Mathematics
1 answer:
MAVERICK [17]3 years ago
6 0

The only other possible meaning I can see is that a2 + b2 means a^2 + b^2. In the case that is a formula that cannot be simplified further, although it could be written as (a + b)^2 - 2ab or (a - b)^2 + 2ab. ... Originally Answered: What is the formula of a2+b2?

For her phone service, Martina pays a monthly fee of $25, and she pays an additional $0.07 per minute of use. The least she has
Mekhanik [1.2K]

Answer: Anything that is 1202 or larger

In other words, m \ge 1202

So we could have m = 1202, or m = 1203, or m = 1204, etc.

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

Explanation:

  • m = number of minutes used
  • 0.07m = amount charged for those minutes used excluding the $25
  • 0.07m+25 = total monthly bill now including the extra $25 fee

The monthly bill is at least $109.14, since this is the lowest amount she has been charged.

\text{monthly bill} \ge 109.14\\\\0.07m+25 \ge 109.14\\\\0.07m \ge 109.14-25\\\\0.07m \ge 84.14\\\\m \ge \frac{84.14}{0.07}\\\\m \ge 1202\\\\

This says that the least number of minutes Martina has used is 1202 minutes.

So if m was a whole number, then m could be selected from the set {1202, 1203, 1204, ...}

Side note: 1202 minutes = 1202/60 = 20.033 hours approximately.

1. Find the value of x. If your answer is not an integer, leave it in simplest radical form.
adelina 88 [10]

Answer:

4\sqrt{73} units

Step-by-step explanation:

The given shape is a right triangle and in right triangles the sum of square length of legs is equal to square length of hypotenuse (represented with x in here):

12^2 + 32^2 = x^2

1168 = x^2 find the root for both sides

4\sqrt{73} =x
