Given:
A right triangle on a coordinate plane.
To find:
The area of a triangle.
Solution:
We know that, the area of a triangle is

From the given figure it is clear that the base of the triangle is 4 units and the height is 3 units. So, the area of the given triangle is



The area of the given triangle is 6 units². Therefore, the correct option is B.
Answer:
B. 
Step-by-step explanation:

The transformations are:
Reflected upon the x axis (x is now negative):

Moved 4 units to the right (instead of just the variable x, you have (x-4)):

And finally moved 3 units down (so now it's minus 3):

A simulation is a mathematical model used to represent a situation.
- A simulation can be a program or a physical test to "simulate" a situation to predict the outcomes.
When we combine two or more simple events we have a compound event
- "Compound" means to combine, like a compound word would be a combination of two words
A Tree Diagram is a diagram that shows all the possible outcomes of an event
- In a tree diagram, each possible outcome "branches" off the main stem, making the final diagram look like a tree with many separating branches.
All the possible outcomes or results is called the sample space
- The outcomes are each different samples, and a sample space is a space that collects each of these samples
When an event is not affected by a previous outcome we have an independent event
- This event is "independent", not affected by other factors, making it an independent event
Let me know if you need any clarifications, thanks!

Answer:
8/pi
Step-by-step explanation:
To find the rate of change from 0 to pi/2 we need the values at 0 and pi/2
f(0) = -4
f(pi/2) = 0
rate of change = change in f(x)/ change in x
= (f(x2) -f(x1))/( x2-x1)
= (0--4) / (pi/2 - 0)
= (0+4) / (pi/2)
= 4 / (pi/2)
= 8/pi
In 7th grade:
red-hair students =58
another color hair students =609
In 8th grade:
red-hair students =60
Let's assume
another color hair students =x
now, we are given
The numbers of red-haired students in 8th grade are proportional to the numbers in 7th
so,

now, we can solve for x
we get

we get

so, students have another color hair in 8th grade is 630.........Answer
