Which point is located at 4, -2?

A. Huixian's mother has 1608  shares of company A. The share price of company B on day 12 is $1.16.

B. To calculate the number of shares of company A that Huixian's mother has, we can use the equation: Shares x Price = $7400. Since we know that the share price of company A on day 7 is $4.60, we can calculate the number of shares of company A by dividing $7400 by $4.60, which is 1608 shares.

To calculate the share price of company B on day 12, we can use the equation: Shares x Price = $5800. Since we know that the number of shares of company B on day 12 is 5000, we can calculate the share price of company B by dividing $5800 by 5000, which is $1.16.

Therefore, the number of shares of company A that Huixian's mother has is 2000 and the share price of company B on day 12 is $0.50.

Answer:

i) To find the maximum height of the projectile, we need to find the highest point that it reaches before falling back to the ground. In this case, the maximum height is the vertex of the parabola. To find the vertex, we can use the formula:

x=-b/2a

(12,845)

Substituting this value back into the original height equation, we find the maximum height:

h = -5(12)^2 + 120(12) + 125 = -300 + 1440 + 125 =845

So the maximum height of the projectile is 845 meters.

ii) To find when the projectile reaches its maximum height, we need to find the x-coordinate of the vertex of the parabola. As we found above, the x-coordinate of the vertex is 12 seconds. So the projectile reaches its maximum height at 12 seconds.

Answer: 20 + x = y.

Step-by-step explanation:

When you deposit, you are adding onto something. Because there is no real value for x, the expression would be 20 + x = y. Also, it would be = y because it says clearly the total amount would be equal to y. and also since why has no value in this context, it would still be y.

Answer:

y = 0.5x + 4

Step-by-step explanation:

1. Move terms to one side of the equation

0.5y - 2= 0.25x +0

The 2x2x2 cube has 6 fully white faces.

A cube is a solid shape with six square faces. Each square face has the same side length and thus all the faces have the same size. A cube has 12 edges and 8 vertices. Each vertex refers to a corner where three edges of a cube meet.

from given conditions, a 2x2x2 cube is made of 8 small cubes of which 4 are blue and 4 are white. the surface of the cube is formed from 6 2x2 squares.

and have to arranged in such a a way that the surface has as many fully white faces (faces white no black color anywhere) as possible.

So, A 2x2x2 cube has a total of 6 faces, and since the goal is to have as many fully white faces as possible, there must be at least 1 fully white face on each of the 6 sides. hence, the 2x2x2 cube has 6 fully white faces.

Therefore, the 2x2x2 cube has 6 fully white faces.

The largest 3 digit number that is divisible by 9 and 7 is 945.

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product. There are two methods of finding factors: multiplication and division.

If a number is divisible by 7 and 9 it shows that 7 and 9 are factors of the number. Since the number is a three digit number, the product of 7and 9 which is 63 will also be a factor.

the highest three digit multiple of 63 is 945.

This means that 945 can be divided by 7 and 9. i.e 945/7 = 135 and 945/9 = 105

Therefore the largest three digit number that can be divisible by both 9 and 7 is 945

What is the ratio of the number?

A ratio shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six .

We know that the ratio of the number of eyes to the number of heads is 5:1. If a monster has 20 eyes, we can set up the equation:

20 eyes = x heads

Where x is the number of heads.

We also know that the ratio of the number of heads to the number of tails is 2:6. We can set up the equation:

x heads = 2y tails

Where y is the number of tails.

We know the number of eyes is 20, therefore x = 20/5 = 4 heads

We also know the number of heads is 4, therefore y = 4*6/2 = 12 tails

Hence, the monster has 4 heads and 12 tails.

The probability that the sample contains two white balls and two red ones is 0.264. There are multiple draws without replacement.

Probability of an event can be expressed as

P(A) = n(A) / n(S)

Where

An urn contains 6 white balls and 15 red balls. A sample of four balls is selected at random from the urn. Find the probability that the sample contains two white balls and two red ones!

It means that there will be multiple draws without replacement.

The total balls are 6 + 15 = 21 balls.

The probability of drawing two white balls and two red ones is

= P(1st is white ∩ 2nd is white ∩ 3rd is red ∩ 4th is red)

= P(1st is white)*P(2nd is white)*P(3rd is red)*P(4th is red)

= (6/21)*(5/20)*(15/19)*(14/18)

= 0.044

There are 6 possible orders (WWRR, WRWR, WRRW, RWWR, RWRW, RRWW). So, the probability in any order would be

= 0.044 × 6

So Isabelle will have to multiply all the quantities in her recipe by a factor of 3.33 (or 333%) to increase the yield to 50 cups.

The percentage that Isabelle needs to multiply her original quantities by to increase the yield from 15 cups to 50 cups is known as the "scaling factor".

To find the scaling factor, you can divide the desired yield by the original yield and multiply by 100 to express it as a percentage:

Scaling factor = (50 cups / 15 cups) x 100% = 3.33 x 100% = 333%

multiplying (1) by - 1 and adding to (2) will eliminate y

- 2x + 3y = - 24 → (3)

add (2) and (3) term by term to eliminate y

8x + 0 = 48

8x = 48 ( divide both sides by 8 )

x = 6

substitute x = 6 into either of the 2 equations and solve for y
