Answer:
Step-by-step explanation:
the first graph has points (-1, -1) and (2, -2)
slope m = (y2-y1) / (x2-x1) = (-1+2)/ (-1-2) = 1/-3 = -1/3
the second graph has points (0, -3) and (2, 0)
slope m = (y2-y1) / (x2-x1) = (-3-0)/ (0-2) = -3/-2 = 3/2
for the table
x. y
-3. 4
0. 1
slope m = dierence in y /diference in x = 4-1 / -3-0 = 3/-3= -1
Answer: 18 and 36 is A.
Step-by-step explanation:
Answer:
Step-by-step explanation:
The volume of a cylinder is:
where 
is the radius and 
is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is 
thus:
Dividing everything between pi:
We can see that the solution for this is 
since 
We have the radius, now we find the height:
42,760 would be written as 4.276 × 10^4 in scientific notation
Answer:
x = 100
Step-by-step explanation:
The area of the left square is 3600
A =s^2
3600 = s^2
Taking the square root of each side
60 =s
The area of the right square is 1600
A =s^2
1600 = s^2
Taking the square root of each side
40 =s
Adding the lengths
60+40 =x
100 =x
