142/80 into mixed number

1 answer:

8 0

80 goes into 142 once, so one is our whole number. there are still 62 / 80 left, so we reduce this fraction. The answer is 1 $\frac{31}{40}$

A satellite television receiver is a parabolic dish with an equation of y=1/32 x^2

choli [55]

Step-by-step explanation:

The equation of a parabola that relates it focus is

${x}^{2} = 4py$

So here, we isolate x^2.

$y = \frac{1}{32} {x}^{2}$

$32y = {x}^{2}$

Next, we factor out 4.

${x}^{2} = 4(8)(y)$

Our p=8 so this tells us the distance of the vertex to the focus.

Angl is a square. The equation of line NG is Y= 1/2 X - 6. Find the equation of line LG in slope intercept form given that the c

Irina18 [472]

Answer: y=-2x-9

Step-by-step explanation:

If ANGL is a square, then NG and LG are adjacent sides.

Adjacent sides are perpendicular. [Each angle is 90°]

The equation of line NG is $Y=\dfrac12 X-6$ .

By comparing it to equation in slope intercept form y=mx+c ( where , m= slope , c=y-interecpt)

slope = $\dfrac12$

Let slope of LG be <em>n</em>, then

$n\times \dfrac{1}{2}=-1$ [Product of slopes of two perpendicular line =-1]

$\Rightarrow n=-2$

Equation of a line passes through (a,b) and have slope m is given by :-

$(y-b)=m(x-a)$

Equation of LG :

$(y-1)=-2(x-(-5))\\\\\Rightarrow\ y-1=-2x-10\\\\\Rightarrow\ y=-2x-9$ [In intercept form]
