Hello!
To find the area of a square use the formula A=lw (Area is equal to length times width) in other words multiply the side times side of just the square. Then to find the area of a triangle use the formula A= 1/2 hb ( Area is equal to half of the height times base) therefore you multiply the height times the base and then multiply it by 1/2 or 0.5 in decimal form ( or just divide by 2, either way works the same). Then add the area of the square and triangle together. (To find the height of the triangle you need to subtract 10 from 16, in other words 16-10. To find the base of the triangle you need to do 10-6.)
Hope this helps!
Answer 4 is true because 123.466 is greater than 123.462
Answer:
see below
Step-by-step explanation:
f(x) = 4x^2 + 8x − 5
To find the x intercepts set y = 0
0 =4x^2 + 8x − 5
Factor
0=(2x-1)(2x+5)
Using the zero product property
2x-1 =0 2x+5 =0
2x=1 2x = -5
x = 1/2 x = -5/2
The x intercepts are ( 1/2 ,0) and ( -5/2,0)
Rewriting in vertex form by completing the square
4 ( x^2 + 2x) -5
4 ( x^2+2x +1) -4*1 -5
4 ( x+1) ^2 -9
Vertex form is
a( x-h) ^2 +k where ( h,k) is the vertex
The vertex is ( -1,-9)
We know it opens upwards since a > 0
Plot the vertex and the x intercepts
The graph is symmetric on based on the vertex
