BC = 20; CD = 15. What is the value of BD − AC.
Answers
Answer:
BD - AC = 0
Step-by-step explanation:
BC = 36 , CD = 15 and BD = x
As these are forming right angled triangle,
Using Pythagorean theorem,
Taking square root on both sides
As the given shape is rectangular, the sides parallel to each other will have same values.
AB = 15 , AD = 36 and AC = x
Now,
BD - AC = 39 - 39 = 0
Hence,
BD - AC = 0

Answers
The graph of the equation defined by; y = f(x) = x² + 20 as represented in the task content is symmetrical about the y-axis.
To which axis is the graph of the equation given symmetrical about?It follows from the task content that the axis about which the given graph is symmetrical be determined as follows.
Since it follows that for a function to be symmetric about the y-axis;
f(-x) = f(x).
Therefore, we have;
f(-x) = (-x)² + 20.
f(-x) = x² + 20 = f(x).
Hence, the graph is symmetrical about the y-axis.
Also; Since; f(-x) = x² + 20 ≠ - f(x).
It follows that the graph is not symmetrical about the origin and hence, the graph is only symmetrical about the y-axis.

The markup indicates the difference between the selling price and the item's cost to the business.In general, a corporation generates more money the higher the markup.The retail price of a product less its cost is known as markup, although the margin percentage is determined in a different way.
Calculate percentage on markup based on cost ?
The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.Selling price = cost + markup
= 1.17+0.78
=1.96
percentage markup based on cost = markup/cost*100
0.78/1.17*100
= 66.66
percentage on selling = percentage on markup cost/100+percentage on cost
= 66.66/100%+66.66

distributed across each month, after how many months will the company recover its
investment in Program X?
Answers
The business will need 10.5 months to make back the money it invested in Program X.
How do you determine monthly costs?Actual or anticipated costs for each monthly expense are needed to calculate the average monthly expenses.
How do you figure out the return on investment?By dividing an investment's net profit (or loss) by its initial cost or outlay, we can determine the return on investment.
Program X costs $35,000 per year, but is anticipated to save $40,000 for Company C in the first year.
Considering that the savings and the cost are equal over the course of each month
So, 40000/35000 = 0.875
No. of months to recover = 0.875 × 12

Answer:
1 These 5 main features are the title, scale, points, labels, and line.
2. Relations are a group of ordered pairs from one set of objects to another set of objects while functions are relations that connect one set of inputs to another set of outputs. So all functions are relations while all relations are not functions.
3. To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
4. The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points. In other words, Pick two points on the line and determine their coordinates.
5. To find the x-intercept of a given linear equation, plug in 0 for 'y' and solve for 'x'. To find the y-intercept, plug 0 in for 'x' and solve for 'y'.
6. An example of a linear equation is: 2x + y - 3 = 0. It can be written in the standard form, the slope-intercept form, and the point-slope form.
