It is D, Nancy Reynolds from Chicago.
The denominator of the exponent is the index of the radical, the base of the exponent is the base of the radical, and the numerator of the exponent is the exponent of the radicand.

Answer:
5.6 = AB
Step-by-step explanation:
Since this is a right triangle, we can use trig functions to find the length of AB
Cos theta = opp side/ hypotenuse
cos 62 = AB / BC
cos 62 = AB /12
Multiply each side by 12
12 cos 62 = AB
5.633658753 = AB
Rounding to 1 decimal place
5.6 = AB
We can also find AC
sin theta = opp side/ hypotenuse
sin 62 = AC / BC
sin 62 = AC /12
Multiply each side by 12
12 sin 62 = AC
10.59537111 = AC
Rounding to 1 decimal place
10.6 = AC
Answer:
Apply cosine rule:
c²=b²+a²-2ba cosC
C= pi/3 = 180/3 = 60 degrees
cosine 60 deg = 0.5
c²=2²+3²-[2×2×3×0.5]
c²=7
c=√7
c=2.645 ;length of third side of angle
Step-by-step explanation:
I think its B. Because 396 divided by 3 equals 132 (there's 3 feet in a yard)
Answer:
E
E is the only one that ends with 70 and is also all multiples of 6.
