The median for that is 5.
Answer:
-12
Step-by-step explanation:
What it means by f(-1) is that x is -1.
So all you do is plug -1 into the x areas like this: -3(-1)^2+2(-1)-7=-12.
To find how much Fiona makes per hour divide her earnings (y) by the number of hours worked (x).
42/3= $14 per hour
Phillip makes $12 per hour.
14-12 = 2
Fiona makes $2 more per hour tan Phillip
The area of a triangle is determined by the formula: Base x Height * 1/2
You'll need to assign a base to the triangle. Based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). The distance between any two numbers is found by just subtracting them. Here, you should subtract the x values to find the distance of this side.
2 - (-2) = 4.
So the distance (aka the length of the base) is 4. The height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). We should subtract the y values this time to find the height/distance.
4 - 1 = 3
So the height is 3.
Base = 4
Height = 3
<h3><u>Question:</u></h3>
Serena uses chalk to draw a straight line on the sidewalk. The line is 1/2 ft long. She wants to divide the line into sections that are each 1/8 ft long. How many sections will the line be divided into?
<h3><u>Answer:</u></h3>
The number of sections that the line is divided is 4
<h3><u>Solution:</u></h3>
Given that, Serena uses chalk to draw a straight line on the sidewalk
The line is 1/2 ft long. She wants to divide the line into sections that are each 1/8 ft long
From given,
To find: Number of sections can be made
The number of sections that can be made is found by dividing the total length of line by length of each section
Substituting the values, we get,
Thus number of sections that the line is divided is 4
