If f(x) = 2x -6+4
Then
f(-2) = 2(-2) -2
f(-2) = -6
Answer:
1/9
Step-by-step explanation:
To find the geometric mean of two numbers, multiply them together, then take the square root
G.M = sqrt( 1/3 * 1/27)
= sqrt(1/81)
= 1/9
Answer:
The first step is to place the compass needle on one of the ends of the given segment AB, and draw an arc above and below the segment AB
Step-by-step explanation:
The steps to construct a perpendicular to segment AB are;
1) Place the compass needle on one of the ends of the given segment AB, and draw an arc above and below the segment AB
2) With the same compass width, place the compass needle on the other end of segment AB, and draw an arc above and below the segment AB intersecting the arcs constructed in step 1 above. Label the point of intersection as C and D
3) With a straight edge, draw a line joining the points of intersection C and D of the two arcs. The line CD. is the perpendicular bisector of the segment AB.
Answer:
10 ft, 14 ft
Step-by-step explanation:
Let b represent the length of the shorter base. Then the longer one is b+4 and the area is ...
A = (1/2)(b1 +b2)h
120 = (1/2)(b +(b+4))(10) . . . . use given values
12 = b+2 . . . . . . divide by 10, simplify
10 = b
14 = b+4
The measurements of the two bases are 10 ft and 14 ft.
