Answer:
Step-by-step explanation:
5, -4
5-4=1
5(-4)=-20
Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
Answer:
A) (4, 36)
Step-by-step explanation:
Substituting 4 into the equation gets y = 9(4), which is equal to 36.
(0,15)(1,45)
slope = (45 - 15) / ( 1 - 0) = 30 mph
Answer:
791.2 ft
Step-by-step explanation:
The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.
where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then
