2. Then simplify and multiply
Answer: Choice D) Slopes are the same
----------------------------------------
Explanation:
The graph of f(x) is a straight line through the two points (0,3) and (1,1). Those points are the left and right points respectively.
Start at (0,3). To get to (0,1), we move 2 units down and 1 unit to the right. Think of the "2 units down" as a "rise of -2". Negative rise means you're really falling.
So the slope of f(x) is
slope = rise/run = -2/1 = -2
slope = -2
The slope of g(x) is also -2
Note how y = -2x-5 is in y = mx+b form
we see that m = -2 is the slope
b = -5 is the y intercept
So that shows why the two functions have the same slope.
Step-by-step explanation:
DC+ da+ bc -180
so now you can calculate
Answer:
3 seconds
Step-by-step explanation:
To find the highest point, we want to find the vertex of the parabola. Since the function will be negative, the vertex will represent the highest point.
To find the vertex we want this equation in vertex form:
y=a(x−h)2+k
and the vertex will be (h,k)
We can expand the equation h(x)=-(x+1)(x-7) to be:
To get the vertex form we need to complete the square.
The vertex form is :
so our vertex is (3,16)
This means the highest point will be 16 when x = 3
Answer:
A= pi r(r+h2+r2)
Step-by-step explanation:
Multiply the radius by pi, then set that aside for a bit.
Square the height and the radius as well, then add those together. This is how it would look:
3.14 x 4 = 12.56
7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56
I think this is the answer. Can't say I'm 100% sure, though.
