Answer:
slope = 
Step-by-step explanation:
Calculate slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= 
=
Answer:
No this is not the same as cos(2Ф)
Step-by-step explanation:
First I changed the 
Ф into 1-
Ф
I then foiled the (1-2Ф)(1-Ф) and that resulted in 1-Ф-2Ф+2
Ф
From there, I then cancelled the two 2Ф and combined like terms and was left with 1-3Ф
Now 1-3Ф ≠ cos(2Ф)
Answer:
Step-by-step explanation:
Remark
You could do this by converting the distance but the much more common way is to use kg and m.
Formula
PE = m * g * h
Givens
m = 40000 grams
m = 40000 grams * 1kg/1000 grams = 40 kg
g = 9.81
h = 35 m
Solution
PE = 40 * 9.81 * 35
PE = 13734 Joules
Answer:
One statement that is true is that it equals 50
Answer:
184
Step-by-step explanation:
in the number 128 the number eight is right it should be to the right then in the number157 one is right it should be to the left in 841 8and 1 are in the wrong position 8 - right 1 - left then in the number 624 the number 4 is right but in the wrong position it should be in the middle the answer is digit 1,8,4
