Determine the horizontal and vertical axis intercepts: r = 36 + 70sin θ.
Please show your work need help!
Answer:
See below for answers and explanations (along with a graph)
Step-by-step explanation:
Refer to the equations for a limaçon:
y=a+bcos∅ (horizontal line of symmetry) and y=a+bsin∅ (vertical line of symmetry) where a/b determines the type of limaçon.
This is an inner loop limaçon because 36/70<1, so its horizontal axis intercepts are 36 and -36 (marked in red) and its vertical axis intercepts are 0, 36+70=106 and 70-36=34 (marked in green)
Select the equation that is in standard form.
a
y=7x+2
b
y-7=x+8
c

the pair of line represented by equation 9x²+12xy+(k+1)y²=0 coincide, find the value of k
Answer:
k=3 is your answer
Step-by-step explanation:
given equation :
9x²+12xy+(k+1)y²=0
comparing above equation with
ax²+2hxy+by²
we get
a=9
h=12/2=6
b=k+1
since lines are coincident
ø=0
Tan0=±[2√(h²-ab)]/(a+b)
we get
h²=ab
6²=9(k+1)
36/9=k+1
4=k+1
k=4-1=3
The value of k will be;
⇒ k = 3
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The pair of equation is,
⇒ 9x² + 12xy + (k + 1)y² = 0
Now,
We know that;
The condition of coincide of pair of line ax² + 2hxy + by² = 0 is,
⇒ h² = ab
So, For the equation of the pair of line 9x² + 12xy + (k + 1)y² = 0, we have;
⇒ 2h = 12
⇒ h = 6
⇒ a = 9
⇒ b = (k + 1)
Substitute all the values in given condition for coincide , we get;
⇒ h² = ab
⇒ 6² = 9 (k + 1)
⇒ 36/9 = k + 1
⇒ 4 = k + 1
⇒ k = 4 - 1
⇒ k = 3
Thus, The value of k = 3

A number is 11 less than 3 times another number. The sum of the numbers
is 25. What are the two numbers?
Can you please send the work too
Step-by-step explanation:
this is simple use it and enjoy
Step-by-step explanation:
Let x be the first number
Let y be the 2nd number
given,
[tex]x = 3y - 11 \\ x - 3y = - 11[/tex]
as equation 1
and
[tex]x + y = 25[/tex]
as equation 2.
Now we will use elimination method to solve for simultaneous equations.
We will use equation 1 - equation 2 to eliminate x to solve for y.
[tex]x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 \div - 4 \\ = 9[/tex]
Substitute y into equation 2.
[tex]x + 9 = 25 \\ x = 25 - 9 \\ = 16[/tex]
The numbers are 9 and 16.

Binaya spent 9/10 of his pocket money. He has Rs 120 left now. Find:. (i) how much money did he spend ? (ii) how much money did he have?
Solving a linear equation we will find that they spent a total of Rs 1.080 and they initially had Rs 1,200.
How much money did he spend?Let's assume that initially they had M money, we know that they spend 9/10 of it, so now they have:
(1/10)*M
And we also know that at the end Binaya had Rs 120, so we can write the linear equation:
(1/10)*M = Rs 120
Solving that for M we will get:
M = 10*Rs 120
M = Rs 1,200
And the amount that they spent is 9/10 of that, so it is:
(9/10)* Rs 1,200 = Rs 1,080
So, they spent a total of Rs 1,080 and they initially had a total of Rs 1,200

Solve: Four more than a number is more than 13
Inequality :
Solution :
Answer:
x + 4 > 13
x > 9
Step-by-step explanation:
In this equation, the value of the "number" is unknown, so I used a variable (x) to represent the unknown value.
FOUR more than x would mean addition.
x + 4.
According to this word problem, four more than x is larger than thirteen, so a greater than symbol was used.
Like this,
x + 4 > 13.
We can find the solution to 'x' by subtracting 4 from 13.
Like this,
13 - 4 = 9
Therefore, the solution is x > 9
And, the inequality is x + 4 > 13.
