Answer:
23
Step-by-step explanation:
The ratios of side lengths in an isosceles right triangle are ...
1 : 1 : √2
Multiplying these by 23 gives ...
23 : 23 : 23√2
The lengths of AT and AP are both 23.
x = 23
_____
If you like, you can use the Pythagorean theorem.
PT² = AP² +AT²
(23√2)² = x² +x²
2(23²) = 2(x²) . . . . . rearrange
x = 23 . . . . . . . . . . . divide by 2, take the square root
The answer is D!
64 divided by 8 is 8!
Answer:
1. n⁶
2. 9r²
3. a^-2 or 1/a²
4. b^-1/2 or (√b)^-1 or 1/(√b)
5. no. 5 isn't clear
8x5 multiplies to be 40, and adds up to be 13.
For finding, the sum of last ten terms, we write the given AP in reverse order i.e, 126, 124, 122,..., 12, 10, 8
Hence,first term (a) = 126, common difference, (d) = 124 - 126
So,
