im not 100%sure tho
Answer:
(y2 - y1) / (x2 - x1)
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Both are D
First one:
f(g(x)) =f(x^2+3) then you x^2+3 is the x you are going to introduce in the function f
f(x^2+3)= sqrroot(x^2+3-3)= sqrroot (x^2) =x
Second:
you need to leave x alone
y = 3x^2 +1
y-1 = 3x^2
(y-1)/3 = x^2
sqrroot ((y-1)/3) = x
sqrroot ((x-1)/3) = h^-1(x)
B or a because they are negative numbers
Answer:
The correct answer is:
D=
Step-by-step explanation:
We have the equation
h = D^2N /2.5 (1)
We have to clear the equation for (1). Multiplying (1) by 2.5
2.5 h = D^2 N (2)
Dividing (2) by N,
= D^2 (3)
By taking the square root of (3), finally we have
= D
