Answers
The coordinates of points C are (4,1).
The coordinates of the points D are (3, 2) respectively.
What is coordinates forumla?y = mx + c. Conversely,is the formula of coordinate that help to find satisfy to the equation y = mx + c is always lie on the line with the gradient m and y-intercept of c.
If the point C is divides AB in the ratio 2:3, then the coordinates of C are;
Xc=2(1)+3(6)/2+3
Xc=2+18/5
Xc=20/5 = 4
Yc=2(4)+3(-1)/2+3
Yc=8-3/5
Yc=5/5 = 1
The coordinates of points C are (4,1).
If the point D divides the AC in the ratio 3:2, then the coordinates of D are-
Xc= 3(1)+2(6)/3+2
Xc=3+12/5
Xc=15/5 = 3
Yc=3(4)+2(-1)/3+2

The equivalent ratio of yellow cars to purple cars in the form n:1 is 1.54:1.
What is Ratio?A ratio is a mathematical comparison between two or more quantities or values. It expresses the relative sizes or amounts of different quantities and is typically represented in the form of a fraction or a colon (:).
The greatest common divisor (GCD) of 97 and 63 is 1, which means they have no common factors other than 1.
Therefore, we can write the ratio of yellow cars to purple cars as: 97:63
Since we need to write it in the form of n:1, we can divide both sides of the ratio by 63 (the smaller number in the ratio):
= 97/63 : 63/63
= 97/63 : 1
= 1.54 : 1
So, the equivalent ratio of yellow cars to purple cars in the form n:1 is 1.54:1.

The urface area of a three-dimenional object i the um of the area of the face. If repreent the length of the ide of a cube, write a formula for the urface area S of the cube
Answers
A Formula for the Surface area of the cube is 6a².
A cube is a three-dimensional solid with six square faces, facets, or sides, three of which meet at each vertex in geometry. It looks like a hexagon from the corner, and its net usually looks like a cross. One of the five Platonic solids, the cube is the only regular hexahedron.
The sum of the areas on each face of the cube that covers it is the cube's surface area. The formula for surface area is six times the cube's length divided by the square of that number. It is denoted by 6a², where a is the cube's side length. It basically refers to the entire surface area.
area of one face = a² [By area of square formula]
There are six faces altogether. Therefore,
TSA (total surface area) of cube = S = a² + a²+ a² + a² + a² +a²

You decide to invest $500 into a 4-year CD that pays 2.85% interest
compounded monthly.
Use the compound interest formula:A = P(1 + r/n) ^nt to give:
a. The future value in 4 years.
b. The interest gained in 4 years.
Answers
Future value in four years is $1060.30 and Interest gained in four years is 560.30.
Define compound interest.Compound interest is interest that builds up over a set length of time on both principal and interest. The principal is also used to account for the interest that has accrued on a principal over time. Furthermore, the accumulated principal value is used to calculate interest for the subsequent time period. The new way of calculating interest now utilized in all international financial and commercial operations is known as compound interest. When we look at the compound interest values that have built over successive time periods, the power of compounding is clearly apparent.
Given
You decide to invest $500 into a 4-year CD that pays 2.85% interest compounded monthly
Compound interest
A = P( 1+ r/n)^nt
Interest gained in 4 years
A = 500( 1+ 0.0285/12)^(12)(4)
A = 500( 1 + 0.002375) ^48
A = 560.30
Future value in 4 years = $500 + $560.30
Future value in 4 years = $1060.30
Future value in four years is $1060.30 and Interest gained in four years is 560.30.

three sides of a triangle are 3, radical7, and 4. Is the triangle acute, right or obtuse?
Answers
Answer: To determine whether a triangle is acute, right, or obtuse, we need to compare the lengths of its sides to the measure of its angles. The triangle is acute if all three angles measure less than 90 degrees, it is right if one angle measures exactly 90 degrees, and it is obtuse if one angle measures more than 90 degrees.
In the case of a triangle with sides 3, radical7, and 4, we can use the Pythagorean theorem to find the measure of its angles. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Since we know that one side of the triangle has length 4, and another side has length radical7, we can use the theorem to find the length of the third side, which is the hypotenuse. We can write this as an equation: 4^2 + radical7^2 = x^2, where x is the length of the hypotenuse. Solving for x, we get x = 5.
Since the length of the hypotenuse is 5, and one of the other sides has length 4, we can conclude that this triangle is a right triangle. Therefore, the triangle is a right triangle and not acute or obtuse.

Answers
Answer:
$28,750
Step-by-step explanation:
To find the price of the car, you need to use the following formula:
price of the car = down payment / (down payment percentage / 100)
Plugging in the given values, you get:
price of the car = 5,750 / (20 / 100)
Simplifying the expression, you get:
price of the car = 5,750 / 0.2
The price of the car is therefore 28,750.
