C is the circle with the equation x^2 + y^2=1
Answer:
a) The equation of the tangent to the circle
x + √3y = 2
b) [tex]a = \frac{-1}{\sqrt{3} } , b = \frac{2}{\sqrt{3} }[/tex]
Step-by-step explanation:
Step(i):-
Given the equation of the circle x² +y² =1
Tangent equation of the circle x² +y² =a² is xx₁ +yy₁ - a² =0
The tangent equation of the given circle
xx₁ +yy₁ - 1² =0
This equation passes through the point ([tex](\frac{1}{2} , \frac{\sqrt{3} }{2} )[/tex]
[tex]x(\frac{1}{2} ) +y(\frac{\sqrt{3} }{2} ) =1[/tex]
⇒ x + √3y = 2
The equation of the tangent to the circle
x + √3y = 2
Step(ii):-
Slope - intercept form y = ax +b
√3y = - x + 2
[tex]y = \frac{-x}{\sqrt{3} } + \frac{2}{\sqrt{3} }[/tex]
where
[tex]a = \frac{-1}{\sqrt{3} } and b = \frac{2}{\sqrt{3} }[/tex]

Write a function using function notation to describe each situation. Find a reasonably domain and range for each function. A newspaper charges $3 per line for the first 4 lines plus a $20 fee to advertize.
Answer:
The answer is below
Step-by-step explanation:
The domain of a function is the set of all independent variables for the function while the range of a function is the set of all possible dependent variables.
Let x represent the number of newspaper lines and f(x) be the charges for advertisement. x is the independent variable and f(x) is the dependent variable.
Since the newspaper charges $3 per line for the first 4 lines plus a $20 fee to advertise, the function is given as:
f(x) = 3x + 20 for 0 < x < 4
But for more than four lines, the charges is given as:
f(x) = 12 + 20 = 32 4 < x < ∞
Therefore, the domain and range of the function is:
Domain = (0, ∞)
Range = (20, 32}
What is the nth term rule of the linear sequence below
5, 8, 11, 14, 17, ...
Tn=
Answer:
The 12th term is 38
Step-by-step explanation:
Step one:
given the sequence 5, 8, 11, 14, 17, ...
We are required to find the nth term
the formula to find the nth term is given as
Tn = a1 + (n - 1 ) d
a1= the first term
n= the number of terms
d= the common difference
d = 8-5= 3 or 11-8= 3
Step two:
Now say we want to find the 12th term of the sequence n=12
substitute
T12= 5+(12-1)3
T12= 5+(11)3
T12= 5+33
T12= 38
The above formula is used to find the general (or nth) term of an arithmetic sequence.

Find the perimeter of triangle ABC with vertices A(6, 3), B(6, - 2) , and C(- 4, 3) .
Answer:
26.2 units
Step-by-step explanation:
We are given the points/vertices
A(6, 3),
B(6, - 2) , and
C(- 4, 3)
Step two
Let us find the distances between the given points/vertices
A-B =A(6, 3) to B(6,-2)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((6-6)²+(-2-3)²)
d=√(-2-3)²)
d=√(-5)²)
d=5 units
B-C=B(6, - 2) to C(-4, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((-4-6)²+(3+2)²)
d=√(-10)²+(5)²)
d=√100+25
d=√125
d=11.2 units
C-A=C(-4, 3) to A(6, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((6+4)²+(3-3)²)
d=√(10)²
d=√100
d=10 units
Hence the perimeter is 5+11.2+10
P=26.2 units
Please I need this ASAP! A couple needs to get a loan of $5,000 and has to choose between three options. • Option A: 2 1/4% compounded quarterly (every 3 monins) o Option B: 3% compounded every 4 months o Option C: 4 1/2% compounded semi-annually If they make no payments for 5 years, which option will give them the least amount owed after 5 years? Use a mathematical model for each option to explain your choice.
Therefore, option A will result in the least amount owed after 5 years.
What is percent?Percent is a way of expressing a number as a fraction of 100. The symbol used for percent is "%". For example, 50% is equivalent to 50/100 or 0.5. Percentages are commonly used to express rates, ratios, and changes in quantity over time.
Here,
To determine which option will result in the least amount owed after 5 years, we need to calculate the total amount owed for each option at the end of the 5-year period. We can use the formula A=P(1+r/n)^(nt) to calculate the total amount owed, where A is the final amount owed, P is the principal (in this case $5,000), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time period in years.
Option A: 2 1/4% compounded quarterly (every 3 months)
The annual interest rate is 2.25%. Since interest is compounded quarterly, n=4. The time period is 5 years, so t=5. Plugging these values into the formula, we get:
A = [tex]5000(1+0.0225/4)^{(4*5)}[/tex]
= $5,827.05
Option B: 3% compounded every 4 months
The annual interest rate is also 3%, but interest is compounded every 4 months. To calculate the effective interest rate per year, we need to convert the compounding period to years. Since there are 3 compounding periods per year (4 months each), the effective annual interest rate is:
(1+0.03/3)³ - 1 = 0.0304 or 3.04%
Using the formula with these values, we get:
A = 5000(1+0.0304)⁵
= $6,079.28
Option C: 4 1/2% compounded semi-annually
The annual interest rate is 4.5%. Since interest is compounded semi-annually (twice per year), n=2. Plugging in the values, we get:
A = [tex]5000(1+0.045/2)x^{(2*5) }[/tex]
= $6,200.92

Answer:
The interest charged is $7.49.
After 29 days, Travis paid a total of $607.49
Step-by-step explanation:
Travis obtained a cash advance for $600.
The interest rate is 0.04305% per day.
The simple interest rate formula is given by:
[tex]I=Prt[/tex]
Where I is the interest, P is the initial amount, r is the rate, and t is the time (in this case in days).
Our initial amount P is $600.
Our interest rate r is 0.04305% or (moving the decimal two places to the left) 0.0004305.
Since Travis repaid the loan after 29 days, our t is 29.
Hence, our interest is:
[tex]I=600(0.0004305)(29)=7.4907[/tex]
So, the interest charged is about $7.49.
So, after 29 days, Travis paid a total of the original $600 plus an interest of $7.49 for a total of $607.49
Answer:
The interest charged is $7.49.
After 29 days, Travis paid a total of $607.49
Step-by-step explanation:
Travis obtained a cash advance for $600.
The interest rate is 0.04305% per day.
The simple interest rate formula is given by:
→ I=Prt
Where I is the interest, P is the initial amount, r is the rate, and t is the time (in this case in days).
Our initial amount P is $600.
Our interest rate r is 0.04305% or (moving the decimal two places to the left) 0.0004305.
Since Travis repaid the loan after 29 days, our t is 29.
Hence, our interest is:
→ I=600(0.0004305)(29)=7.4907
So, the interest charged is about $7.49.So, the interest charged is about $7.49.So, after 29 days, Travis paid a total of the original 600 plus an interest of 7.49 for a total of $607.49Dan invests £11125 into his bank account.

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is a line segment as shown in the image.
We can write the equation as -
(4r - 3) + (r + 7) = 29
4r + r - 3 + 7 = 29

Let's say we have a box with 6 marbles: 3 red, 1 blue, 1 green, and 1 yellow. What is the probability of picking a yellow marble, returning it to the box, and then picking a blue marble?
1/12
1/30
1/36
1/11
Answer:
1/12
Step-by-step explanation:
you have 1/6 chance at drawing it once (one yellow marble, six total), so 1/12 to draw it twice.
The probability of picking a yellow marble, returning it to the box, and then picking a blue marble will be 1/36. Option C is correct.
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that, we have a box with 6 marbles: 3 red, 1 blue, 1 green, and 1 yellow.
We have to find the probability of picking a yellow marble, returning it to the box, and then picking a blue marble.
The probability of picking a yellow marble, returning it to the box, and then picking a blue marble is obtained as,
=1/6 × 1/6
=1/36
Thus the probability of picking a yellow marble, returning it to the box, and then picking a blue marble will be 1/36. Option C is correct.
