Answer:

It can be a factor if you have f(-1) = 0

That's binomial theorem as I remember.

What equation in slope intercept form represents the line that passes through the two points? (5, 6), (9, –2)

timofeeve [1]

First find slope
(-2-6)/(9-5) = -8/4 = -2
Y = -2x + b
6 = -2(5) + b, b = 16
Solution: D

The sides of a rectangle are in the ratio 4:7. If its longer side is 31.5 in., find the shorter side, the perimeter, and the are

Lemur [1.5K]

Answer:

Width = 18 inches

Perimeter = 99 inches

Area = 567 square inches

Step-by-step explanation:

The sides of a rectangle are in the ratio 4:7. Then

Width $=4x$ in

Length $=7x$ in.

If its longer side is 31.5 in, then

Length = 31.5 in

and

$7x=31.5\\ \\x=\dfrac{31.5}{7}=4.5\ in$

So,

Width $=4\cdot 4.5=18\ in$

The perimeter is

$P=2(\text{Width}+\text{Length})\\ \\=2(18+31.5)\\ \\=2\cdot 49.5\\ \\=99\ in$

The area is

$A=\text{Width}\cdot \text{Length}\\ \\=18\cdot 31.5\\ \\=567\ in^2$

Please help me with this problem

Answer:

Step-by-step explanation:

In standard form, an ellipse's major axis is indicated by the $a^{2}, b^{2}$ terms like this:

$\frac{{(y-k)}^{2}}{a^{2}}+\frac{(x-h)^{2}}{b^{2}}, a>b$

$\frac{{(x-h)}^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}}, a>b$

In the top equation, the vertical axis is primary and in the second the horizontal axis is primary. That's a bit more info than the question asked, but I thought it may be helpful to understand the answer.

Now, a co-vertex is the intersection point between an ellipse and its minor axis. On the graph of the ellipse, the $b$ is the distance from the center to where the ellipse intersects its minor axis, so our answer is A.

If a graphical representation would be helpful, I would take a look at the Math Warehouse article on the Equation of an Ellipse in Standard Form.
