It passes through (-1,4) and is perpendicular to the x axis

line x=4 is perpendicular to x-axis. So line, which is perpendicular to x=4 line, will be parallel to x-axis, therefore it is perpendicular to y-axis. Line, which is parallel to x-axis, has zero slope. Its equation, therefore, is y=0x+b or simply y=b. Since it shall pass through point (1,-4), its coordinates must satisfy the line equation. x does not matter, since there is no x in equation y=b, thus only y-coordinate matters. Plug in -4 into the equation, to obtain -4=b. So y=-4 is your answer. Answer: y=-4

Express the area of the triangle shown below in terms of b and θ only.

Paul [167]

Given a right triangle with base, b and height, h with the angle opposide side h as θ.

The area of a triangle is given by
$A= \frac{1}{2} bh$

But,
$\tan\theta= \frac{h}{b} \\ \\ \Rightarrow h=b\tan\theta$

Therefore, the area of the triangle in terms of <span>b and θ only is given by
$A= \frac{1}{2} b(b\tan\theta)= \frac{1}{2} b^2\tan\theta$ </span>

How can you tell whether the parabola had a vertical or horizontal shift?

Schach [20]

If the x is squared, the parabola is vertical (opens up or down). If the y is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.

Name the kind or kinds of symmetry the following figure has: A

denpristay [2]

It is a straight line of symmetry because if you have a paper A and you fold it, it will form a straight line, and that is also meaning a straight line of symmetry. If you fold it any other way, it will not be a line of symmetry.

Hope this helps you ;)
