Answer:
31.95
Step-by-step explanation:
(184.26 × 64.284) ÷ (4 × 92.692)
Solve :
= 11844.96 / 370.77
= 31.95
First we'll show this is a right triangle by the Pythagorean Theorem:
Since we have a right triangle, by the (converse to the) Pythagorean Theorem. We also see it's isosceles, AB=AC.
That's the end of the homework but I'll go on a bit.
Another way to show perpendicularity, essentially the same as the other two, is by a zero as the dot product of the sides as vectors, differences between vertices.
Vector AB = B - A = (3,2)
Vector AC = C - A = (-2, 3)
AB · AC = 3(-2) + 2(3) = 0
A zero dot product means
AB ⊥ AC
Answer:
2 (x-4) (x-2)
Step-by-step explanation:
2x^2-12x+16
Factor out a 2
2( x^2 -6x +8)
Now we factor the inside term
What multiplies to 8 and add to -6
-4*-2 =8
-4+-2 = -6
2 (x-4) (x-2)
Answer: 7 track practices
Step-by-step explanation: IN order to find out how many runs it would take to run 35, we must first find out how many miles he runs in one track practice. SO:
15/3 = 5
with a ratio of 5:1, it becomes much easier:
35/5 = 7
Answer:
x =52
Step-by-step explanation:
bith angels together make 180° so 180-128=52
