Hello there! The answer is A. Octagon.
A. Octagon- An octagon is an 8-sided shape.
B. Pentagon - A pentagon is a 5-sided shape.
C. Hexagon - A hexagon is a 6-sided shape.
D.Triangle - A triangle is a 3-sided shape.
This means that A is the correct choice since 8 is greater than 5, 6, or 3. I hope this helped answer your question!
Answer:
Temperature drops to -10 deg C after 5.5 minutes and remains at that temperature.
Step-by-step explanation:
Answer:
D, E &F
Step-by-step explanation:
Lets's go down the list and evaluate each choice
A. (3^8) / (3^4) = 3^ (8-4) = 3^4 (≠ 3^2)
B. 6²/2 = (2 x 3)²/2 = (2²·3²)/2 = 4·3²/2 = 2.3² (≠ 3^2)
C. (3^5) ·(3^3) = 3^ (5+3) = 3^8 (≠ 3^2)
D 3·3 = 3^2 (Answer)
E. (3^12) / (3^10) = 3^ (12 -10) = 3^2 (Answer)
F. (3^-3) / (3^-5) = 3^ [ -3 -(-5) ] = 3^ (-3 + 5) = 3^2 (Answer)
Answer:
9.75 feet
Step-by-step explanation:
You use the pythagorean theorem to solve. A is the unknown, while b is 7 feet, and c is 12 feet
A^2 + 7^2 = 12^2
A^2 + 49 = 144
Subtract 49 from both sides to get
A^2 = 95
then take the square root of both sides to get
A (the height) = 9.74679434481
I usually round to 2 decimal points to get the answer 9.75 feet.
Use quadratic formula to solve (shown in picture):
We would get two answers:
x = .3808
and
x = -18.381
