Answer:

The correct answer is B

Step-by-step explanation:

Let's understand the graph.

A line is drawn starting in 4.5 and involving all numbers greater than 4.5.

But notice that in the starting point the line is drawn with an open circle, this means that the line does not consider 4.5 as part of its domain, this means that 'k' values are greater than 4.5.

Values greater than 4.5 are represented as >4.5, then:

k>4.5, which is option B, because:

k>9/2 = k>4.5

Note: Option A (k≥4.5) means that the line involves 4.5 as part of its domain, which is false as mentioned before.

P and W are twice-differentiable functions with P(7)=2(W(7)). The line y=9+2.5(x-7) is tangent to the graph of P at x=7. The lin

Using the product rule, we have

$m(x) = x W(x) \implies m'(x) = xW'(x) + W(x)$

so that

$m'(7) = 7W'(7) + W(7)$

The equation of the tangent line to W(x) at x = 7 has all the information we need to determine m' (7).

When x = 7, the tangent line intersects with the graph of W(x), and

y = 4.5 + 2 (7 - 7) ==> y = 4.5

means that this intersection occurs at the point (7, 4.5), and this in turn means W (7) = 4.5.

The slope of this tangent line is 2, so W' (7) = 2.

Then

$m'(7) = 7\cdot2 + 4.5 = \boxed{18.5}$

Answer:

I wont be able to graph it for you, best way is to use desmos or wolfram alpha. This is very easy but since i cant draw it would be difficult to explain. Sorry.
