Answer:
parallel
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slopes m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)
m = 
= 
Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)
m = 
=
Since slopes are equal then parallel
The airplane's speed in the direction of its heading is
.. 410 mph +r*cos(θ)
where θ is the angle between the plane's heading and the direction the wind is moving toward.
That is, if the plane is moving "with the wind," its speed is (410 +r) mph.
If the plane is moving "against the wind", its speed is (410 -r) mph.
Answer:
hello : y = 3x² -24x +26 ......answer: C
Step-by-step explanation:
y = 3(x-4)² -22
by idetity : (x-4)² = x²- 8x+16
y = 3(x²- 8x+16 ) -22
y = 3x² - 24x +48 -22
y = 3x² -24x +26 ......answer: C
You need to multiply 8.7 by 3.14.You should get 27.318
