Answer:
hb=6.72cm
Step-by-step explanation:
A=hbb
2
A=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forhb
hb=﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
2b=﹣244+2·(24·25)2+2·(24·7)2﹣254+2·(25·7)2﹣74
2·25=6.72cm
Answer:
a) f(x) = -2x² + 4x
Explanation:
To find the standard form we need to solve the equation as:
So, the standard form is f(x) = -2x² + 4x
To make the graph we will use the initial form because when the equation is written like f(x) = a(x-h)²+k, the coordinate (h,k) is the vertex of the parabola
So, in this case, the vertex of the parabola is the point (1, 2)
On the other hand, we can find a point in the graph. For example, if x is equal to 0, then f(x) is equal to:
f(x) = -2(x-1)² + 2
f(0) = -2(0-1)² + 2
f(0) = -2(-1)² + 2
f(0) = - 2 + 2
f(0) = 0
So, the parabola passes through the point (0,0) and has a vertex in the point (1, 2). Then, the graph is:
Answer 3/4w+8=w-7
3/4w-w= -7-8
-1/4w= -15
w= 60
