Answer:
Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:
For this triangle we know that 
and . We substitute these values in the equation and solve for B.
Now we use the quadratic formula to solve the equation.
For an equation of the form 
the quadratic formula is:
In this case note that: 
Then:
The solutions are:
For this problem we take the positive solution.
Now we substitute the value of B in the equation to find the height h
Answer:
Step-by-step explanation:
y²-x⁴
y=9, x=2
9²-2⁴ = 81-16 = 65
A strong positive correlation means that as one variable increases so does the other and that they do so in a linear relationship. So what this means is that “as the rainfall increases, the number of peaches a tree produces increases.”
It does not mean that the rainfall causes the tree to produce more peaches. The correlation only establishes that the two variables are related in that one increases as the other does. It is NOT the case that this means for sure one causes the other. We cannot assume causality when using a correlation.
It might be that the rain causes more peaches to grown or it might be that some other factor or combination of factors causes the growth. We just do not know.
A. -1 Because you would divide 3x and -6 by 2.
