Answer:
39
Step-by-step explanation:
to find the area of the triangles use the equation
3(5)(.5)=7.5
since we have 4 triangles, multiply that by 4, which equals 30
Now find the area of the square
3(3)=9
Now add the area of the square and the area of the triangles
Answer:
is the correct answer.
Step-by-step explanation:
Given that function f(x) is:
f(x) is a quadratic function in x, meaning that it has a maximum power of 2 of x.
Vertex form of quadratic function is given as:
i.e. we make whole square of terms of .
Now, let us try to make whole square term of .
Adding and subtracting 1 from RHS:
Now, using the formula:
The given function becomes:
It is comparable to vertex form i.e.
where a = 1, h = 1 and k = -7
Hence, the <em>vertex form </em>of given function is:
0.5 is 10 times greater than 0.05
