m∠1 = m∠5, because alternate exterior angles are congruent.

Angles formed by intersecting two parallel lines with a transversal are known as angles in parallel lines.

Given:

lines a and b intersect a transversal, c.

The pair of angles on the outside of the two parallel lines but on the other side of the transversal are known as alternate exterior angles.

m∠1 = m∠5 (Alternate exterior angles are congruent)

n = 37, and tenth term = 18

Given progression,

36, 34, 32, ...

The sum of the first n terms is 0

First term(a1) = 36

The common difference (d)= 34-36 = -2,

The formula of the sum of the first n term is,

\(Sn = \frac{n}{2} [2a_{1} + (n - 1)d]\)

substitue the values Sn= 0, a1= 36, d= -2 in the above equation to find n

\(0\)= \(\frac{n}{2} [2(36) + (n-1) (-2)]\)

\(0 = \frac{n}{2}[72- 2n+ 2]\)

\(0 = \frac{n}{2}[74 - 2n]\)

\(74 - 2n = 0\)

\(2n = 74\)

\(n = \frac{74}{2}\)

\(n = 37\)

n = 37

The formula for finding the nth term(10th term):

\(a_{n} = a1 + (n - 1)d\)

n = 10, a1 = 36, d = -2

\(a_{10} = 36 + (10-1)(-2)\)

\(a_{10} = 36 + 9(-2)\)

\(a_{10} = 36 - 18\)

\(a_{10} = 18\)

\(a_{10}\) = 18

The equation of the tangent line to the astroid at the point (-3√3, 1) is: y = -(3√3)^(1/3)x - 3(3√3)^(1/3) + 1

To find the equation of the tangent line to the astroid at the point (-3√3, 1), we need to first find the slope of the tangent line.

We can do this by taking the derivative of the equation of the astroid with respect to x, and then evaluating it at the point (-3√3, 1).

Taking the derivative of x²/³ + y²/³ = 4 with respect to x, we get:

(2/3)x^(-1/3) + (2/3)y^(-1/3) * dy/dx = 0

Solving for dy/dx, we get:

dy/dx = (-x^(1/3))/y^(1/3)

Substituting x = -3√3 and y = 1, we get:

dy/dx = (-(-3√3)^(1/3))/(1^(1/3)) = -(3√3)^(1/3)/1

So the slope of the tangent line at the point (-3√3, 1) is -(3√3)^(1/3).

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line. The point-slope form is:

y - y1 = m(x - x1)

Substituting x1 = -3√3, y1 = 1, and m = -(3√3)^(1/3), we get:

y - 1 = -(3√3)^(1/3)(x + 3√3)

Simplifying, the equation of the tangent line to the astroid at the point (-3√3, 1) is:

y = -(3√3)^(1/3)x - 3(3√3)^(1/3) + 1

a)  The value of d⁻¹(1001) = 0110.

b) As the function, g ο f is not well-defined.

c) The resulting set is {001, 101, 001, 101, 011, 111, 011, 111}, which is the range of g ο f.

d) The value of (f ο d)(1011) = 1111.

(a) d⁻¹(1001) is asking us to find the input value of d that would produce the output 1001. Since d removes the second bit and places it at the end,

=> d(1001) = 0110.

Therefore, d⁻¹(1001) = 0110.

(b) The composition of functions f and g, denoted as f ο g, means applying function g first and then function f.

In this case, f's range is {0001, 1001, 0101, 1101, 0011, 1011, 0111, 1111}, which is a subset of g's domain. Therefore, f ο g is well-defined.

However, g's range is {000, 001, 010, 011, 100, 101, 110, 111}, which is not a subset of f's domain. Therefore, g ο f is not well-defined.

(c) The range of g ο f is the set of all possible outputs when we apply f first and then g. To find the range of g ο f, we need to evaluate all possible inputs of f and apply g to the output.

Since f's range is

=> {0001, 1001, 0101, 1101, 0011, 1011, 0111, 1111},

we can apply g to each element to get the range of g ο f.

The resulting set is {001, 101, 001, 101, 011, 111, 011, 111}, which is the range of g ο f.

(d) To evaluate (f ο d)(1011), we first apply d to 1011 to get 1110, and then we apply f to 1110 to get 1111.

Therefore, (f ο d)(1011) = 1111.

1) We can explain why the area is πr² by assuming the figure as a rectangle, 2) Diameter = 24.20 cm, Area = 452.91 cm² and 3) the area of the table is 1074.66 in²

The circle is a 2D geometrical figure, with no side or angle, and is made a collection of points.

Given that, 1) a circle with circumferences = 2πr and radius = r, 2) a circle having circumferences = 76 cm and 3) Jada is painting a table having diameter 37 in.

1) Assume the figure as a rectangle, (refer to attached figure)

We get, the length of it is πr and width is r.

And the area of a rectangle is = the Product of length and width.

So, we can conclude that the area of this rectangle is = πr×r = πr²

Therefore, by assuming the figure as a rectangle, we can explain why the area of a circle is πr²

2) circumferences = 2πr

2πr = 76

πr = 38

r = 38/3.14  (π ≈ 3.14)

r = 12.01 cm

Diameter = 2r

D = 2x12.01 = 24.20 cm

Area = πr²

= 3.14x12.01²

= 452.91 cm²

3) Diameter = 37 in

r = 37/2 = 18.5 in

Area = πr²

= 3.14x18.5²

= 1074.66 in²

Therefore, the area of the table is 1074.66 in²

Hence, the answers are 1) We can explain why the area is πr² by assuming the figure as a rectangle, 2) Diameter = 24.20 cm, Area = 452.91 cm² and 3) the area of the table is 1074.66 in²

The length of the curve r = 4θ², 0≤θ≤2√3, is 38.786 units.

To find the length of the curve, we can use the formula for arc length:
\(L = \int_{a}^{b}\sqrt{(1 + (dy/dx)^2)} dx\)

In this case, we have the polar equation r = 4θ², which we can convert to Cartesian coordinates using x = r cos(θ) and y = r sin(θ):

x = 4θ² cos(θ)
y = 4θ² sin(θ)

To find dy/dx, we can use the chain rule:

dy/dx = (dy/dθ)/(dx/dθ)

= (4θ² cos(θ) + 8θ sin(θ))/(8θ cos(θ) - 4θ² sin(θ))

Simplifying this expression, we get:

dy/dx =(4θ) (θ cos(θ) + 2 sin(θ))/(2 cos(θ) - θ sin(θ))

Now we can substitute this expression and the expression for x into the arc length formula:
\(L = \int_{0}^{2\sqrt{3}}\sqrt{(1 + ((4\theta)(\theta cos(\theta) + 2sin(\theta))/(2cos(\theta) - \theta sin(\theta)))^2)} d\theta\)

This integral is difficult to solve analytically, so we can use numerical methods to approximate the value. Using a calculator or computer program, we get:

L ≈ 38.786

So the length of the curve is approximately 38.786 units.

Answer:

Exponents, often known as powers, are a type of mathematical notation that shows how many times a base value should be multiplied by itself. They are frequently stated as a base value raised to the power of an exponent. For instance, 3^2 represents 3 to the power of 2, which is 3 x 3 = 9.

To evaluate an exponent, do the multiplication specified by the exponent. 533, for example, is 5 increased to the power of 3, which becomes 5 x 5 x 5 = 125. If the exponent is negative, it signifies that the reciprocal of the base value should be multiplied by itself the number of times specified by the exponent's positive version. For example, 2(-3) denotes the reciprocal of 2, 1/2 increased to the power of 3, which is (1/2) x (1/2) x (1/2) = 1/8.

Furthermore, exponents can be coupled utilising exponent laws such as the product law, power law, and quotient law. These principles allow for the simplification and manipulation of exponentiated expressions.

If there are factors that could affect his TV watching time, such as a special event or illness, the range of possible values may be wider.

What is mean ?

Mean can be defined as ratio of sum of observations and total number of given observations.

We can use the formula for mean absolute deviation (MAD) to determine the range of values within one MAD of the mean:

MAD = sum(|x - mean|)/n

where x is the value of each observation, mean is the average of all the observations, and n is the total number of observations.

Since the MAD is given as 7, we can plug in the values and solve for the sum of absolute differences:

7 = (|x1 - 21| + |x2 - 21| + ... + |x6 - 21|)/6

Multiplying both sides by 6 gives:

42 = |x1 - 21| + |x2 - 21| + ... + |x6 - 21|

Since the mean is 21, the sum of all observations must be 21 times the number of observations, which is 6 in this case. Therefore:

x1 + x2 + ... + x6 = 6*21 = 126

We can use this information to solve for the possible values of x7 within one MAD of the mean:

|x7 - 21| <= 7

-7 <= x7 - 21 <= 7

14 <= x7 <= 28

So, any value of x7 between 14 and 28 hours is within one MAD of the mean. Therefore, the possible numbers of hours of television for week 7 that are within the mean absolute deviation are:

14 hours

15 hours

...

28 hours

Note that these values are based on the assumption that Liam's TV watching habits do not change significantly from week to week.

Therefore,  If there are factors that could affect his TV watching time, such as a special event or illness, the range of possible values may be wider.
