How do you simplify 6 to the power of 2 plus 15

Mathematics
1 answer:
Sonja [21]2 years ago

Answer:

D

Step-by-step explanation:

6 to the power of 2 just means 6 squared. To solve this, just multiply 6 by itself. 6x6 is 36. Now, we have to add that to 15. 36+15 is 51.

Therefore, the correct answer is D!

Hope I helped!!!!!!!!!

1. Write out the law of cosines and find the hypotenuse of triangle with 2 sides lengths equal to three and the included angle m
LUCKY_DIMON [66]

Answer:

1.) \sqrt{13.341}  ≈ 3.652

2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.

Step-by-step explanation:

I think we may have the same class so hopefully this helps:

1.) a^2 = b^2 + c^2 - 2bccosA --> law of cosines formula.

   a^2 = 3^2 + 3^2 - 2(3)(3)cos(75) --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.

   a^2 = 18 - 18cos75 --> in between steps.

   a^2 = 13.341 --> more simplifying.

   a(hypotenuse) = \sqrt{13.341} or 3.652 --> answer

2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.

Good luck! :)

A nut mixture of peanuts and pecans at a small fair is $1.00 per pound of peanuts and $2.85 per pound of pecans. Over the entire
CaHeK987 [17]

Answer:

  B.  (12.0, 85.0) There were 12.0 pounds of peanuts and 85.0 pounds of pecans sold at the fair

Step-by-step explanation:

Subtract the first equation from the second:

  1.85n = 157.25

  n = 157.25/1.85 = 85 . . . . . divide by the coefficient of n

Only one answer choice has 85 pounds of pecans—the one shown above.
