If f(x)=2x+4 and g(x)=3x-7; then find f^-1(x)
Answer:2x + 4
Step-by-step explanation:
if you divide two linear binomials, you will get a quotient that is a monomial with a remainder. Use long division.
2/3
___________
(3x - 7) | 2x + 4
2x - (14/3)
___________
(14/3) + 4
Quotient is 2/3
Remainder = (14/3) + (12/3) = 26/3
To check, we multiply the quotient by the divisor, then add the remainder to the result.
(2/3)(3x - 7) + (26/3) =
2x - (14/3) + (26/3) =
2x + (12/3) =

Which illustrates the construction of the bisector of an angle
Answer:
Option 3
Step-by-step explanation:
The bisection of an angle is the division of that angle into two equal angles. The bisection of an angle is done by drawing a line (known as angle bisector) that splits the angle into two angles of equal measure.
Below shows how to bisect an angle:
First draw two straight line with your ruler to form an angle.Place the compass pin at the point of the angle and draw an arc to cross each of the angle lines.At each of the two points the arc touches the angle line, place your compass and then draw an arc in such a way that the two arcs intersect.Using a ruler draw a line from the point of the angle to the intersection of the two points.4 thousandths times 3 (like this plz 0.004x3)

A daycare has a sandbox that is a prisms with regular hexagons as its base. The sandbox has a base area of 1,146 square inches and has a height of 13 inches. If the sandbox is only filled to 85% capacity with sand, how much sand is needed for this sandbox
Answer: 12663.3 cubic inches sand is needed for this sandbox.
Step-by-step explanation:
Formula : Volume of cuboid = Base area x height
Volume of sandbox = 1146 x 13 = 14898 cubic inches
Quantity of sand required to fill = 85% of Volume of sandbox
= 0.85 x 14898 [85% = 0.85 ]
= 12663.3 cubic inches
Hence, 12663.3 cubic inches sand is needed for this sandbox.
