Which equation has a slope of 6 and intercepts the y-axis at -4?
Answer:
The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept.
If the slope of the line is 6 and the y-intercept is -4, the equation of the line is y = 6x - 4. This equation describes a line with a slope of 6 that intercepts the y-axis at the point (0, -4).
A ball is dropped from 2 meters and rises up by 75%
The height of ball which is droped from 2m and rises to 75% after third bounce is equals to the 0.843 meters.
If an object is thrown from high and has a bouncing feature, each bouncing is less than the initial height until it stops. Each bounce reduces the growth rate until it reaches zero. In order to calculate the height of each bounce, so we can estimate what percentage the object will reach after each bounce. If we get the percentage of each bounce, we can easily determine the height of each bounce. We have, a ball is droped from 2 meters and bounce up to 75%. That is height of first bounce is determined by using percentage, height is 2 m × 75% = 2 m×0.75 = 1.5 m
In second bounce, height is 1.5 m × 75%
= 1.5 m×0.75 = 1.12 m
In third bounce, 1.12 m× 75%
= 1.12 m×0.75 = 0.843 m

What are the domain and the range of function f?
The domain and the range of function f are given as follows:
Domain: (-∞, -3) U (-3, 6) U (6, ∞).Range: (-∞, 0) U (0, 1/9) U (1/9, ∞).How to obtain the domain and the range of a function?The domain of a function is the set that contains all the input values that can be assumed by the function.
The function in this problem is a fraction, meaning that the denominator must assume values different of zero, hence the values outside the domain are:
x² - 3x - 18 = 0.
(x - 6)(x + 3) = 0
Hence:
x + 3 = 0 -> x = -3.x - 6 = 0 -> x = 6.Hence the domain is:
(-∞, -3) U (-3, 6) U (6, ∞).
The range of a function is the set that contains all the output values that can be assumed by the function.
The x - 6 term can be canceled, hence the output value that the function will never assume is of:
1/(6 + 3) = 1/9.
And also y = 0, as it would assume a value of zero at x = 6 but the denominator would also be zero.
Hence the range is of:
(-∞, 0) U (0, 1/9) U (1/9, ∞).

The number of units produced does not affect net operating income when using _____ costing.
The number of units produced does not affect net operating income when using absorption costing.
All production expenses, including direct materials, direct labour, and both variable and fixed overhead costs, are included in the cost of each unit produced in absorption costing. This means that as more units are manufactured, the total manufacturing cost is distributed over a greater number of units, resulting in a reduced cost per unit.
Variable costing, on the other hand, includes only variable production expenses, such as direct materials, direct labor, and variable overhead costs, in the cost of each unit produced. Fixed manufacturing overhead costs are considered period expenses and are not included in the product cost.

1 - cos² 15° - cos² 75°
Answer:
1 - cos² 15° - cos² 75° can be simplified as follows:
Using the identity cos² x = 1 - sin² x, we can write the expression as:
1 - (1 - sin² 15°) - (1 - sin² 75°)
= sin² 15° + sin² 75° - 1
Using the identity sin 2x = 2sin x cos x, we can write sin 15° and sin 75° in terms of sin 30° and sin 45°:
sin 15° = sin (30° - 15°) = (1/2) * sin 30°
sin 75° = sin (45° + 30°) = sin 45° + sin 30°
Substituting these values in the above expression, we get:
sin² 15° + sin² 75° = (1/4) * sin² 30° + sin² 45° + sin 30° * sin 45°
= (1/4) * (2 * (1/2)²) + (2 * (1/2) * (1/2)) + (1/2) * (1/2)
= (1/4) + 1/2 + 1/4 = 1
So, 1 - cos² 15° - cos² 75° = sin² 15° + sin² 75° - 1 = 1 - 1 = 0.

we colored all points of r2 with integer coordinates by one of six colors. prove that there is a rectangle whose vertices are monochro- matic. can we make the statement stronger by limiting the size of the purported monochromatic rectangle?
Yes, we can make the rectangle has sides of length n and n, and all four vertices have the same color
A rectangle is a two-dimensional shape with four sides, two of which are parallel and equal in length, and the other two sides are also parallel and equal in length.
In this case, the objects are the points in the plane with integer coordinates, and the available spaces are the six colors.
Since there are an infinite number of points with integer coordinates and only six colors, it follows that there must be a color that appears at the vertices of a rectangle.
In other words, we can color the points in a manner such that there will be a rectangle in which all four vertices are the same color. This is because, if we divide the points into six different regions, there must be at least one region that contains more points than the others.
When we look for a rectangle, we look for two points in this region that are the farthest apart from each other. The rectangle that connects these two points will have all four vertices the same color.
In conclusion, we can make the statement stronger by limiting the size of the purported monochromatic rectangle.

Answer:a=275 b =525
Step-by-step explanation:
Hi there, here's your answer:
Given:
a and b are integers
a + b = 800 ....(i)
b = a + 250
Putting value of b in (i)
a + (a + 250) = 800
2a + 250 = 800
2a = 800 - 250

The probability that I get a head in the coin toss and a letter card is 2/ 13.
Therefore the answer is 2/ 13.
There are 4 As, 4Qs, 4Ks and 4 Js, so there are 16 choices. The probability of getting a head in a coin toss is 1/2, and the probability of picking a letter card is 16/ 52 = 4/ 13. So
P(heads) = 1/ 2
P(letter card) = 4/ 13
To find the joint probability of both events happening (getting a head and picking a letter card), you multiply the individual probabilities:
P(heads and letter card) = P(heads) * P(letter card)

kevin has four red marbles and eight blue marbles. he arranges these twelve marbles randomly, in a ring. determine the probability that no two red marbles are adjacent.
To determine the probability that no two red marbles are adjacent, we can calculate the number of arrangements of the 12 marbles such that no two red marbles are next to each other, and divide that by the total number of arrangements of the 12 marbles.
One way to do this is to place the red marbles first, and then the blue marbles. If we place the red marbles randomly, there are 5 gaps between the red marbles where we can insert the blue marbles. Thus, there are 5! = 120 ways to arrange the blue marbles.
Next, we need to determine the number of ways to arrange the red marbles. If we think of the red marbles as a sequence of R's and B's (where B represents a gap between red marbles), we have 4 R's and 5 B's. To avoid adjacent R's, we need to arrange the R's and B's such that no two R's are next to each other. One way to do this is to use the concept of combinations.
There are C(9,4) ways to arrange 4 R's and 5 B's in a sequence of 9 elements. This number can be calculated using the formula for combinations: C(n,k) = n! / (k! (n-k)!). In this case, C(9,4) = 126.
Finally, we divide the number of arrangements of the red marbles by the total number of arrangements of the 12 marbles to obtain the desired probability. The total number of arrangements of the 12 marbles is 12!. Thus, the desired probability is:
P = 126 / (120 * 12!) =
126 / (120 * 479001600)
= approximately 0.0000026
So, the probability that no two red marbles are adjacent is approximately 0.0000026.

(starting amount), r is the interest rate expressed as a decimal, n is the number of times per
year that the interest is compounded, and t is the time in years.
After 7 years, the balance of the savings account will be $1069.39.
What is balance in savings account?An account balance is the amount of money in a financial repository at any particular time, such as a savings or checking account. The account balance is always the net amount after all debits and credits are subtracted.
The formula to calculate the balance after t years is A = P(1 + r/n)^(nt), where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years.
In this case, P = 700.00, r = 0.07, n = 1 (since the interest is compounded annually), and t = 7. Plugging these values into the formula, we get:
A = 700.00 * (1 + 0.07/1)^(1 * 7)
A = 700.00 * (1.07)^7
A = 700.00 * 1.527674
A = $1069.39
