What is another way to write 4 hundreds?

Answers

Answer 1

Answer: There is 3 form that mostly used in math: standard form, expanded form and word form. In this question, 4 hundred would be word form. So, to write 4 hundred in a different form the answer would be:

Standard form: 400
Expanded form : 4x100

Write the definition of a function absoluteValue, that receives an integer parameter and returns the absolute value of the parameter's value. So, if the parameter's value is 7 or 803 or 141 the function returns 7, 803 or 141 respectively. But if the parameter's value is -22 or -57, the function returns 22 or 57 (same magnitude but a positive instead of a negative). And if the parameter's value is 0, the function returns 0.

Answers

Answer:

Step-by-step explanation:

The value absolute is the function $|*|: \mathbb{R}\rightarrow \mathbb{R}^+$ defined by $|x|= x$ if $x$ is a positive number and $|x|=-x$ if $x$ is a negative number.

Derive the equation of the parabola with a focus at (2, −1) and a directrix of y = −one half.f(x) = −(x + 2)2 − three fourths
f(x) = (x + 2)2 + three fourths
f(x) = −(x − 2)2 + three fourths
f(x) = −(x − 2)2 − three fourths

Answers

Basically, the parabola has to have all points that are equidistant from the focus and the directrix, the directrix being a horizontal line, and the focus being a point given. To derive an equation from this you need to use the distance formula which I'm guessing you already know because you're already in precalc.
The gist of it is that we have a random point on the parabola (x,y), and the point (x,y) will be equidistant from both the focus and the directrix. If we use the distance formula, you get something like this:
$\sqrt{(y-(- (1)/(2) ))^2} = √((x-2)^2+(y-(-1)^2)$
The square root of y-(-1/2) coming from the directrix, and the righthand side of the equal sign being derived from the focus.
All you need to do is simplify now!
$(y+(1)/(2))^2 = (x-2)^2+(y+1)^2 \n\ y^2+y+ (1)/(4) = x^2-4x+4 + y^2+2y+1 \n\ -y-(3)/(4) = x^2-4x+4 \n\ -y-(3)/(4) = (x-2)^2 \n\ -y = (x-2)^2+(3)/(4) \n\ y = -(x-2)^2-(3)/(4)$

Hope I helped!

Answers

for two line segments to be parallel, their slopes must be equal.

Therefore slope of AB must be equal to slope of CD

which is, option 3
(y4-y3)/(x4-x3)=(y2-y1)/(x2-x1)

the complete question in the attached figure

we know that

Two lines are parallel if they have the same slope.

Computing for the slope of line segment AB and line segment CD using the formula

$m=((y2-y1))/((x2-x1))$
