Answer:
-1,-6
Step-by-step explanation:
The reflection of point P=(-1,6) across the x-axis is the point (-1,-6).
What is reflection?In mathematics, reflection is a transformation that flips a shape, point, or object over a line, plane, or point. Reflection is also known as flipping, mirroring, or symmetry.
In two-dimensional geometry, the most common type of reflection is a mirror reflection, which involves flipping a shape or point over a line (known as the line of reflection) to create a mirror image. The line of reflection acts as a mirror, and the shape or point is reflected in the mirror as if it were a real reflection.
To find the reflection of the point P=(-1,6) across the x-axis, we can use the following formula:
Rx-axis(P) = (x, -y)
where x is the x-coordinate of P, and y is the y-coordinate of P.
In this case, the x-coordinate of P is -1, and the y-coordinate of P is 6. Therefore, the reflection of P across the x-axis, Rx-axis(P), is:
Rx-axis(P) = (-1, -6)
So the reflection of point P=(-1,6) across the x-axis is the point (-1,-6).

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

An account earns simple interest. Find the annual interest rate. Interest = $60 principle = $500 time = 2 years Please help!!
Answer:
A = $560.00
Step-by-step explanation:
I = A - P = $60.00
Formula:
[tex]A = P(1 + rt)[/tex]
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 500(1 + (0.06 × 2)) = 560
A = $560.00
The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.

What is revenue?Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.
Total Revenue = Number of Units Sold X Cost Per Unit
According to the question
a> The company wants to reduce total expenses to $1,300.
Then expenses would i cut is from
Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.
b>After the decision the impact will be on profit is
It will increase our profit by $1,300 as
Profit = Sales - Expenses
c>if the company increases prices 20%
i.e
If price will be increases then revenue will also increase by 20%
As Total Revenue = Number of Units Sold X Cost Per Unit
Therefore ,
Total Revenue = 356500 * 1.2
= 427800
d> If the cost of supplies (inputs) decreases,
The impact on profit is it will increase
as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .
e> If the supply of a product goes down,
It will lower the revenue or sales also
as Total Revenue = Number of Units Sold X Cost Per Unit
But if supply of a product goes down and price per unit increase it will maintain the sales or revenue .

What is the differentiation of (sin3x-cos4x)(tan6x+sec8x)
Answer:
expanded:
y = sin(4x)*sin(4x)*cos(3x)
need to use the product rule and chain rule
look at individual derivatives, use chain rule
d/dx sin(4x) = 4cos(4x)
d/dx cos(3x) = -3sin(3x)
put it together using product rule
dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)
simplify
dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)

Given
Stephanie wants to raise at least $800
she plans on selling VIP tickets for $20 each and general admission for $40 each
suppose there are x and y tickets for VIP and general admission

Answer:
32 years
Step-by-step explanation:
Given data
Principal= $5
Rate= 5%
FInal amount= $25
Time=???
Applying the compound interest formula for time
t= ln(A/P)/r

t= ln(5)/0.05
t= 1.60/0.05
t= 35 years
Hence the time is 32 years
math question, evaluation
Answer:
P = 131 degrees
Step-by-step explanation:
We know that the sum of the interior angles of a triangle is 180 degrees
The exterior angles shown form a straight line with the corresponding interior angle
So the two interior angles can be calculated
The sum of two angles on a straight line is 180 degrees
By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180
Thus;
P + (180-162) + (180-149) = 180
P + 18 + 31 = 180
P = 180-31-18
P = 131

The total cost of the tent is 409.86
------------------------------------------------------
explanation:
230×0.65=149.50
230+149.50=379.50×.08=30.36
379.50+30.36=409.86
(Hope this helps :) )
============================================================
Explanation:
65% = 65/100 = 0.65
65% of 230 = 0.65*230 = 149.50
When applying markup, the store increases the cost by $149.50 to get the retail price of 230+149.50 = 379.50, which is the price the customer sees. This is the price before tax.
As a shortcut, we can say 1.65*230 = 379.50 because 1.65 = 1 + 0.65 = 100% + 65%. So 1.65 effectively means "increase the value by 65%"
Similarly, the multiplier 1.08 means "increase by 8%". The cost after tax would be 1.08*379.50 = 409.86 which is the answer
----------
As an even quicker shortcut, we can do both increases at once to say:
1.65*1.08*230 = 409.86
The order of multiplication doesn't matter. The two multipliers 1.65 and 1.08 can be combined into 1.65*1.08 = 1.782 which represents a 78.2% increase overall. After the mark up and tax are considered, the jump from $230 to $409.86 is 78.2%
We can apply the percent change formula to confirm this
A = old value = 230
B = new value = 409.86
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (409.86-230)/230 ] * 100%
C = 0.782 * 100%
C = 78.2%
So it might be tempting to say 65% + 8% = 73%, but as you can see above, that calculation is not true.
