Answer:
B
Step-by-step explanation:
1.2 x 3.7 nearest tenth
1 x 4 nearest whole number
B
Cos² 2x = (1+cos 4x )/2
cos² 6x = (1+cos 12x)/2
subtract to get 1/2 (cos 4x - cos 12x )
= 1/2 (2 sin 4x sin 8x ) as cos A - cos B = 2 [ sin (A+B)/2 sin (A-B)/2 ]
so the answer
A) Plot a point at (0, 3000), then subtract 10 for every second that passes by.
B) The slope is negative because the skydiver is falling and the graph is plotting his descent, his x intercept is at (300, 0) which means he will touch land after 300 seconds
To find the the x intercept, make y equal 0 so 0=-10x+3000, subtract by 3000 on each side, and you end up with -3000=-10x, you then divide both sides by -10 and you end up 300=x or x=300
Answer:
For part 1:
-2x^6 + 7x^4 + 3x^3 - 3x^2 + 11x + 20
For part 2:
Based on the foiling of both, they are equal.
Step-by-step explanation:
(-2x^3 +x -5)( x^3 -3x-4)
What we need to do is foil one by one.
I’ve attached a picture of this.
Once you foil, you add like terms.
Now for part 2, x^3 -3x-4 and -2x^3 +x -5, we do the same process.
