Is it true or false? And how

Mathematics
1 answer:
olasank [31]3 years ago
5 0

The answer is false.

Counterexample:

If a = 4 and b = 2

(4 - 2)^2 = 4

4^2 - 2^2 = 12

Since these answers are not the same this equation is false.

Melissa's employer matches retirement funds 1:2 up to 6% of salary. She makes $55,000 per year. How much should she contribute t
gtnhenbr [62]

Answer: $1100

Step-by-step explanation:

The employer contributes, along with Melissa, in the ratio of 1:2

Up to 6% of $55000, therefore 6/100 x 55000 = 3300

Split in the ratio of 1:2, she will contribute 1/3 of 3300 = 1100

and the employer will contribute 2/3 of 3300 = 2200

Need to find A and B, I already found C
Semenov [28]
I'm going to assume you've learn sin, cos, and tan. To find a you must do:
sin^{ - 1}  =  \frac{a}{12}
Once you find a, you can use the Pythagorean Theorem to find b:
{a}^{2}  +  {b}^{2}  =  {c}^{2}
Or you can do:
cos^{ - 1}  =  \frac{b}{12}
You can find these functions on a scientific calculator. Let me now if you need more help.
