Since you are working with exponents and roots you would add the exponents together. The ninth root of x is equal to x^(1/9) and since you are using it four times your answer would be x^(4/9).
I believe it is A. I did this awhile ago.
this is when i realized i screwed up tryna solve this is mit head oof
Answer:
4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
I hope this helps!
Answer:
Step-by-step explanation:
The Pythagorean theorem is expressed as
Hypotenuse² = opposite side² + adjacent side²
If the distances of the routes given are Pythagorean triples, then they obey the Pythagorean theorem hence, they would form a right angle triangle.
1) for the bus routes between stop A, B and C,
13² = 12² + 5²
169 = 144 + 25 = 169
A Pythagorean triple is formed hence, stop A, B and C form a right angle triangle.
2) for the bus routes between stop C, E and E,
22² = 14² + 18²
484 = 196 + 324 = 520
A Pythagorean triple is not formed hence, stop C, E and E do not form a right angle triangle.
3) 25² = 9² + HJ²
625 = 81 + HJ²
HJ² = 625 - 81 = 544
HJ = √544 = 23.32
4) EG² = 15² + 8²
EG² = 225 + 64
EG² = 289
EG = √289 = 17
