I think B. Would be the answer
Answer:
A. m(-1)^(n-1)
Step-by-step explanation:
The degree of m doesn't change so none of the expressions with n as an exponent of m can possibly be correct. That leaves only choice A.
_____
You will find that when alternating signs are required, the term (-1)^n will be a factor. An offset of ±1 can be added to the n to make the initial sign be what you want. Here we want +1 for n=1, so an exponent of (n-1) is appropriate.
Answer:
m= 72/37
Step-by-step explanation:
36 x 2 - m = 6^2m
Multiply the numbers:
72 - m = 6^2m - 72
Subtract 72 from both sides:
-m - 36m = 36m - 72 - 36m
Simplify:
37m= -72
Divide both sides by 37:
-37m/-37 = -72/-37
Simplify:
72/37
Answer:
93.4 cm²
Step-by-step explanation:
Area of the shaded region = area of the square - area of half of the circle
Area of the shaded region = s² + ½(πr²)
Where,
r = 6.2 cm
s = length of square = diameter of circle = 2*r = 2*6.2
s = 12.4 cm
Plug in the values
Area of the shaded region = 12.4² - ½(π × 6.2²)
= 153.76 - 60.381411
= 93.378589
≈ 93.4 cm² (nearest tenth)
