Easy ok o goes in the middle -1 goes on the left at the end and -2 goes next the -1 and +4 goes on the right at the end but count 1 2 3 and at the fourth line it goes there

She underestimated by 60 cents. To get this answer all you need to do is multiply 1 dollar times 12 which is $12 and then multiply $.30 by 12 and that gives you $3.60. Then you add the $12 to the $3.60 and that gives you $15.60 which is 60 cents over the estimation.

WILL DO ABSOLUTELY ANYTHING FOR THIS ONE HELP ASAP TIMES

Rina8888 [55]

Given:

The graph of a function $y=h(x)$ .

To find:

The interval where $h(x)>0$ .

Solution:

From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, $h(x)>0$ for $x$ and $x>3.6$ .

The function between x=0 and x=3.6 lies below the x-axis. So, $h(x)$ for $0$ .

Now,

For $-1$ , the graph of h(x) is above the x-axis. So, $h(x)>0$ .

For $0$ , the graph of h(x) is below the x-axis. So, $h(x)$ .

For $1$ , the graph of h(x) is below the x-axis. So, $h(x)$ .

Only for the interval $-1$ , we get $h(x)>0$ .

Therefore, the correct option is A.

Find the directional derivative of f at the given point in the direction indicated by the angle θ.

anygoal [31]

Answer:

Directional derivative = 1/√2

Step-by-step explanation:

We are given f(x, y) = y cos(xy)

Now, we know that;

∇f(x, y) = ycos xy

Thus, applying that to the question, we have;

∇f(x, y) = [-y² sin xy, cos (xy) - xy sin xy]

At coordinates (0,1),we now have;

∇f(0, 1) = [-1²•sin0, (cos 0) - 0]

∇f(0, 1) = [0, 1]

Now, unit vector indicated by the angle θ is given as; u = [cos θ, sin θ]

From the question, since θ = π/4, thus

u = [cos π/4, sin π/4]

Cos π/4 in surd form is; 1/√2

Also, sin π/4 in surd form is; 1/√2

So, u = [1/√2, 1/√2]

Directional derivative = [∇f(0, 1)] • u

= [0, 1] × [1/√2, 1/√2] = 0 + 1/√2 = 1/√2
