A rain gutter is to be constructed from a metal sheet of width 36 cm by bending up one-third of the sheet on each side through an angle θ. A. show that the cross-sectional area of the gutter is modeled by the function; A(θ)=144sin(θ)+144sin(θ)cos(θ).

B. For what angle θ is the largest cross-sectional area achieved?

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
