1. Y-Intercepts are where the graph crosses the y-axis. For a parabola, this occurs once, at (0, -3) in the graph shown.

2. X-Intercepts are where the graph crosses the x-axis. For a parabola, this occurs twice, at (-1, 0) and (3, 0) in the graph shown.

3. A parabola that is positive opens upwards, while a parabola that is negative opens downwards. Therefore, this parabola is positive.

Hope this helps!! :)

If a and b are complements, then which of the following is true about the probability of b based on the probability of a?

Vesnalui [34]

Answer:

Option 2 is true.

Step-by-step explanation:

Th sum of probabilities of two complementary events is one, which implies

P(A) + P(B) = 1

So,

P(B) = 1 - P(A)

Evaluate/find all “real” solutions to m squared +4 =0

laiz [17]

Answer:

There is no real solution

Step-by-step explanation:

m^2 = -4

to find m would be a complex number and that would be

m = 2i

but you don't need to find that

At what points does the curve r(t) = ti (6t − t2)k intersect the paraboloid z = x2 y2? (if an answer does not exist, enter dne.)

Usimov [2.4K]

$\mathbf r(t)=t\mathbf i+(6t-t^2)\,\mathbf k=x(t)\mathbf i+y(t)\mathbf j+z(t)\mathbf k$

$\implies z=x^2y^2\iff 6t-t^2=t\times0=0\impiles t(6-t)=0\implies t=0,6$

At $t=0$ , you have $\mathbf r(0)=0\mathbf i+0\mathbf j+0\mathbf k$ .

At $t=6$ , you have $\mathbf r(6)=6\mathbf i+0\mathbf j+0\mathbf k$ .
