Answer:

6 because the insurance price doesn't matter. You subtract the insurance from 480 and have 450. Then you divide by 75

What role does gravity and inertia play in our Solar System?

Varvara68 [4.7K]

It keeps the planets in orbit.

Inertia is what keeps an object moving (in the same direction). Gravity is the pull of an object to another.

The planets have reached the perfect medium to where inertia keeps the planets moving (instead of remaining completely still in space), and gravity pulls them toward the sun so that they move around it instead of moving straight past it or straight into it.

This is also true about the Earth and the moon.

This is also true with satellites in orbit.

What are the vertex focus and directrix of a parabola with equation x=y^2+14y-2

zimovet [89]

This is a sideways opening parabola, opening to the right to be more specific, since the leading coefficient is a positive 1. The rule for a focus and a directrix is that they are the same number of units from the vertex (in other words, the vertex is dead center between them), and that the vertex is on the same axis that the focus is. We need to find the vertex then to determine what the focus and the directrix are. We will complete the square on that to find the vertex. Begin by setting it equal to 0, then move the 2 over by addition to get $y^2+14y=2$ . Now we will complete the square on the y terms. Take half the linear term, square it, and add it to both sides. Our linear term is 14. Half of 14 is 7, and 7 squared is 49. So we add 49 to both sides. $y^2+14y+49=2+49$ , which of course simplifies to $y^2+14y+49=51$ . The purpose of this is to find the k coodinate of the vertex which will be revealed when we write the perfect square binomial we created during this process: $(y+7)^2=51$ . Moving the 51 back over by subtraction gives us $(y+7)^2-51=x$ . The vertex then is (-51,-7). The formula to find the focus using this vertex is $(h+ \frac{1}{4a},k)$ . As I stated quite a while ago, the leading coefficient on our parabola was a +1 so our "a" value is 1, and the focus is then found in $(-51+ \frac{1}{4},-7)$ which simplifies to $(-50.75, -7)$ . If the vertex is (-51, -7) and the focus is (-50.75, -7), then the distance between them is 1/4, or .25. That means that the directrix is also .25 units from the vertex, but in the other direction. Our directrix is a vertical line, and it will have the equaion x = -51.25. Summing up, your focus is (-50.75, -7) and your directrix is x = -51.25

About 3.9 * 10 ^ 7 people live in California. About 1.3 * 10 ^ 6 people live in Maine. About how many more people live in Califo

TiliK225 [7]

Answer:

3.7*10⁷ people.

Step-by-step explanation:

Estimated population of California = 3.9*10⁷ people

Estimated population of Maine = 1.3*10⁶ people.

Let x represent the estimated number of people that live in California more than Maine.

The number of people that live in California more than Maine can be found by finding the difference between the population of California to Maine.

No. Of people living in California - no. Of people living in Maine = estimated no of people that live in California more than Maine.

X = 3.9*10⁷ - 1.3*10⁶

X = 3.7*10⁷ people

About 3.7*10⁷ people live more in California than Maine

Of the three properties, reflexive, symmetric, and transitive that define the relation "is equal to," which one could also apply

yan [13]

Answer: Transitive property.

Step-by-step explanation:

First, for the equality we have:

Reflexive:

For all real numbers x, x = x.

Symmetric:

For all real numbers x, y

if x= y, then y = x.

Transitive:

For reals x, y and z.

if x = y, and y = z, then x = z.

Now, let's talk about inequalities.

first, the reflexive property will say that:

x > x.

This has no sense, so this property does not work for inequalities.

Now, the reflexive.

If x > y, then y > x.

Again, this has no sense, if x is larger than y, then we can never have that y is larger than x. This property does not work for inequalities.

Not, the transitive property.

if x > y, and y > z, then x > z.

This is true.

x is bigger than y, and y is bigger than z, then x should also be bigger than z.

x > y > z.

And this also works for the inverse case:

x < y and y < z, then x < z.

So the correct option is transitive property.
