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
Assuming no limitations on the starting and ending city, then there are 8 choices for the first city, 7 for the second, 6 for the third....
Total number of choices = 8*7*6*...*2*1=8!=40320
Answer:
Step-by-step explanation:
The x- intercepts of the graph are the roots expressed in factorization form.
In this Case :
When y=0
X=2 or x=1/2
Therefore the factorization expression is: (x-2)(x-1/2) =0
Answer:
27
Step-by-step explanation:
tan^1(12/16)
tan^1(0.75)=36.87° ~ 37°
12/sin(37°)=19.94 ~ 20
x=20/tan 37°
x=26.54 ~ 27
System 1 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 1 to three times the second equation in system 1.
