Angle between the pair of straight lines is zero therefore the lines are parallel.
Hence proved
Angle between the pair of straight lines is zero therefore the lines are parallel.
What is parallel lines?Parallel lines can be defined as two lines in the same plane that their angle of inclidation is equal and never meet.
Given,
x²+6xy+9y²-4x+12y-5=0
Comparing the equation with the general equation of 2nd degree
ax² + ay² + 2gx + 2fy + c = 0
so a=1, b=9, h= 3, g=-2, f=6, c=5
Angle between a pair of straight lines that is
tan∅=[tex]\frac{2\sqrt{h^{2} -ab} }{a+b}[/tex]
tan∅=[tex]\frac{2\sqrt{3^{2} -(1)(9)} }{1+9}[/tex]
tan∅=0°
∅=0°
Hence Angle between the pair of straight lines is zero therefore the lines are parallel.

Answer: The answer is No, it's not a scaled factor. That's my answer, you can figure it out why it's no.
Step-by-step explanation:
tan39= x/68
Plz help. Will give brainliet
Answer:
x = 55.06531425, or 55
Step-by-step explanation:
(x/68) = tan(39)
Set up your equation and rearrange it.68 * (x/68) = 68 * tan(39)
On the left side, with 68 * (x/68), the 68's cancel out and leave us with x.On the right side, with 68 * tan(39), we need to first solve for tan(39) and multiply it by 68. Continuing the right side, tan(39), when using a calculator, is 0.8097840332 (make sure your calculator is in degree mode), and when this is multiplied by 68, this makes 55.06531425.x = 55.06531425, or 55
Solve for x!Answer:
[tex]\huge\boxed{x \approx 55}[/tex]
Step-by-step explanation:
We need to note that this is an equation, in which we can solve for x.
[tex]tan(39) = \frac{x}{68}[/tex]
We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.
We now have the formula simplified down to [tex]0.81 = \frac{x}{68}[/tex]. To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.
We know have [tex]0.81 \cdot 68 = x[/tex]
[tex]0.81 \cdot 68 = 55.08 \approx 55[/tex], so x is approximately 55.

On 31 Jan 2021: Debit Interest expense for $250; Debit Note payable for $578.64; and Credit Cash for $828.64.
On 28 Feb 2021: Debit Interest expense for $247.11; Debit Note payable for $581.53; Credit Cash for $828.64.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
On January 1, 2021, Tropical Paradise borrows $50,000 by agreeing to a 6%, six-year note with the bank. The funds will be used to purchase a new BMW convertible for use in promoting resort properties to potential customers. Loan payments of $828.64 are due at the end of each month with the first installment due on January 31, 2021.
Record the issuance of the installment note payable and the first two monthly payments.
The explanation to the answer is now given as follows:
Date Account Title Dr ($) CR ($)
01 Jan 2021 Cash 50,000
Note payable 50,000
(To record $50,000 borrowing through 6% Note from the bank.)
31 Jan 2021 Interest expense (w.1) 250
Note payable (w.2) 578.64
Cash 828.64
(To record first month interest expense paid and part payment of $50,000 note.)
28 Feb 2021 Interest expense (w.4) 247.11
Note payable (w.5) 581.53
Cash 828.64
(To record second month interest expense paid and part payment of $50,000 note.)
Workings:
w.1: Interest expense = First month interest expense = (Interest rate / 12) * Loan amount = (6% / 12) *$50,000 = $250
w.2: Note payable = First month part payment of note payable principal = Monthly payment - First month interest expense = $828.64 - $250 = $578.64
w.3: Loan balance after first month = Loan amount - First month part payment of note payable principal = $50,000 - $578.64 = $49,421.36
w.4: Interest expense = Second month interest expense = (Interest rate / 12) * Loan balance after first month = (6% / 12) *$49,421.36 = $247.11
w.5: Note payable = Second month part payment of note payable principal = Monthly payment - Second month interest expense = $828.64 - $247.11 = $581.53
I honestly don’t understand can some please help?
Answer:
400$
Step-by-step explanation:
since he receives 20 percent of the sales and he receives 80 dollars. Then 80 dollars is 20 percent of the sales. Now, we can change 20 percent into a fraction, 20 percent is 20/100 or 2/10, now there are 5 twos in a ten so we multiply 2/10 by 5, since 2/10 right now is 80 dollars you multiply 80 by 5
80*5=400, so the sales of the week was 400 dollars
Hope this helps :)
Answer:
Thus, the sales of the week were $400
Step-by-step explanation:
Percentages
The salesman receives a 20% commission on all his sales.
One week the company pays $80 as commission.
This means that $80 corresponds to 20% of the sales.
To find the sales, we just divide the commission by the percentage (expressed as a decimal) as follows:
Sales = $80 / (20/100)
Sales = $80 / 0.20
Sales = $400
Thus, the sales of the week were $400

David borrows $15,000 for a new car. He is charged 6% simple interest per year. If he paid $4500 in interest, how many years did it take him to repay the loan?
Answer:
5 years
Step-by-step explanation:
Given that:
Amount borrowed = principal = p = $15000
Interest % per year = r = 6% = 0?06
Total Interest paid = $4500
Number of years it took to repay the loan (t) =?
Simple interest = (p * r * t)
4500 = (15000 * 0.06 * t)
4500 = 900t
4500 / 900 = t
5 = t
It tool 5 years to repay the loan

Explain how to find the product of 12.2(1.45).
Answer:
First, multiply the numbers. Then count the number of decimal places in each factor. Place the decimal in the product so the product has the same number of decimal places as both factors combined.
Step-by-step explanation:

The difference of the squares of two positive consecutive even integers is 84. Find the integers.
Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.
[tex](x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20[/tex]
Applying the difference of squares, and solving the equation, it is found that the numbers are 20 and 22.
----------------------
The two consecutive even integers are: n and n + 2.The difference of the squares is given by:[tex]D_s = (n+2)^2 - n^2[/tex]
Expanding the difference:
[tex]D_s = n^2 + 4n + 4 - n^2[/tex]
[tex]D_s = 4n + 4[/tex]
----------------------
The difference is 84, thus:
[tex]D_s = 84[/tex]
Now, we solve for n.
[tex]4n + 4 = 84[/tex]
[tex]4n = 80[/tex]
[tex]n = \frac{80}{4}[/tex]
[tex]n = 20[/tex]
----------------------
Thus, the numbers are: [tex]n = 20[/tex] and [tex]n + 2 = 20 + 2 = 22[/tex]
