Answer:
108 cm^2
Step-by-step explanation:
rectangle + 2 triangle = total area
L x W + 2 * 1/2 base * height = total area
(5x12) + 2 * 1/2 * 12 * 4 = total area
60 + 48 = 108 cm^2
Answer:
M= the slope. ( it would be the first one)
Step-by-step explanation:
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis. What is the coordinate on the y-axis where the graph of y = 2x + 3 crosses y-axis?
Answer: Ok, i will use the hint provided.
We call x1 and x2 to te two mínima of f, that is
.
The convexity condition says that, if f is differentiable, then the graph of f(x) lays above all the tangents between X and Y, if Y>X then
where
.
then, if we took Y = x1 and X = x2, we have
because f'(x2) = 0.
now if we took Y = x2 and X = x1, we have
because f'(x1) = 0.
Then, x1 = x2. Which implies that we only have one minima.
