Answer:

f(3) = 10

Step-by-step explanation:

f(3) = 2(3)^2 - (3) - 5

f(3) = 2(9) - (3) - 5

f(3) = 18 - 3 - 5

f(3) = 10

Precipitation for the month of March was 6 ½ inches less than average. In April, the precipitation was 2 ⅜ inches less than aver
deff fn [24]

Answer:

The precipitation for both March and April was 8 7/8 inches below average

Step-by step explanation;

For the month of march, precipitation was 6 1/2 inches less than average

For the month of April, precipitation was 2 3/8 inches left.

Now we want to calculate how many inches less than average was precipitation in both wants

What we simply do here is to add the inches with which they were both left than average in both months

That would be;

6 1/2 + 2 3/8

= 13/2 + 19/8 = (52 + 19)/8 = 71/8 = 8 7/8 inches

Please draw and label a figure for this sentence in geometry
Kaylis [27]

Answer:

First, plot points A & B on a graph.

Collinear just means 3 or more points in a straight line (because just 2 points are always collinear, since a straight line can always be drawn through two points.

The instructions don't state a specific area in which points C & D have to be in, so you can put them anywhere, as long as they are collinear with each other, but not any other points,

  • i.e. putting three units up and two units left of points A & B

So let's make up some points for C & D that are on a straight line.

  • Remember, this line does <em>not</em> have to be horizontal! As long as it's a straight line, any direction will do.

Here are some points that you can choose from:

  • C(-1, 1); D(-1, -1)
  • C(4, 5); D(4, -5)
  • C(3, 4); D(3, 5)
  • Anything that doesn't fall on x=2 or y=±3.

For "F" just pick a set of coordinates off to the side and label it

  • F(-3,-6)
  • F(-4, 8)
  • F(6, -7)

You can even use half values if you want:

  • (0.5, 3.2)
  • (1.2, -4.1)
  • (-9.1, -0.2)

As long as your plotted points meet the criteria:

  1. C & D are <em>Collinear</em>
  2. A, B, C, D, & F must not land on the same straight line.
