Identify an equation in point slope form for the line perpendicular to
Vaselesa [24]
Point slope form is y2-y1=m(x2-x1).

The slope m that is perpendicular to y=-4x-1 will be 1/4 (the opposite reciprocal). Then you can use (-2,7) as the x and y values to plug into the formula:

y-7=1/4(x+2) is the answer.

A computer that normally costs $890 is on sale with a 35% discount. What is the sale price?
astraxan [27]

Answer:

578.5$

Step-by-step explanation:

first we calculate 35% of $890

890 * 0.35 = 311.5$

Then we subtract 35% from the original price to obtain the final price

890-311.5=578.5$ <---- final price

Add $178 + $98.25= $276.25
Then $276.25 - $19.50 = $256.75

If the angle is preserved, which describes the effect of moving the plane closer to the cone's vertex? Check all that apply.
Sholpan [36]

Let's go though the choices.

Major axis will get shorter.  TRUE, CHECK ME

As the plane moves closer to the vertex the ellipse stays the same shape but shrinks.

Ellipse will become a circle.  FALSE

As long as the plane is tilted, the ellipse can't be a circle.

Ellipse will degenerate to a point.  TRUE, CHECK ME

Eventually the plane gets to the vertex, at which point (ha!) we have a single point.

Nappes?  Is that a word?   FALSE

The plane needs a steeper angle, steeper than the generators, before it can pass through both halves.

The generators are the lines through the vertex that form the cone.  The plane isn't steep enough to hold any of them. FALSE
