I think it is not true because all sides are triangle except the one on the bottom is a square
1. 87.5 you have to multiply
2. Its 35 because you have to multiply
Hello there!
There are two ways to find the minimum value of this function, but before I show you how, I am going to teach you a little bit about minimum value.
The minimum value on a parabola is the vertex or turning point. This means that the slope of the tangent line is horizontal, having a slope of 0.
The algebraic way to find the minimum or maximum value on a parabola is to use the formula -b/2a. Let's do it...
y=4x^2+4x-35
where a=4, b=4, and c=-35
-b/2a
-4/2(4)
-4/8
-1/2
Now let me show you the other way...
Take the derivative of
y=4x^2+4x-35
y'=8x+4
And set it equal to 0...
8x+4=0
8x=-4
x=-1/2
We got the same answer. Now that we know x=-1/2, plug this into the original equation to find y.
y=4x^2+4x-35
y=4(-1/2)^2+4(-1/2)-35
y=-1-2-35
y=-38
So the minimum point on this parabola is (-1/2,-38)
I really hope th
Answer:
Gretta would be 2500 meters tall
Step-by-step explanation:
2km=2000 and the 1/2 would be 1/2=500 so the answer it 2500
Pls mark brainliest!!!!
Answer:
Step-by-step explanation:
hello :
f(x) =-2x²+4x+1 Completing The Square : f(x) =2(x²+2x)+1
f(x) = -2((x²-2x+1)-1)+1
f(x) = -2((x-1)²-1)+1
f(x) =2(x-1)²+1 ... verex form when the vertex is (1,1)
the axis of symmetry is x=1
