The size of the angle after the transformation is 124 degrees

The transformation is described by

Rotation by degrees around a center 0

The measure of the angle is given as

Angle = 124 degrees

There are four types of transformation, and they are:

The representation of the types of transformation are:

As a general rule of rotation:

When a shape, line or an angle is rotated, the size of the angle in the rotated figure remains unchanged

This means that the angle remains 124 degrees

Using the Factor Theorem, the polynomial is factored as follows:

f(x) = (x - 2)(x + 1)(x² + 2).

The Factor Theorem states that a polynomial function with roots(also called zeros) [tex]x_1, x_2, \codts, x_n[/tex] is given by the following rule.

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient of the polynomial, determining if it is positive(a positive) or negative(a negative).

In this problem, the polynomial is given by:

f(x) = x^4 - x³ - 2x - 4.

This polynomial is factored applying the inverse factor theorem, finding the roots of the polynomial, which are given as follows:

For the complex roots, we have that 1.41² = 2, hence the term corresponding to the two complex roots is:

x² + 2.

Then the complete factored polynomial is:

f(x) = (x - 2)(x + 1)(x² + 2).

Answer:

Step-by-step explanation:

For number 8 the answer is y=2x+7 because our equation is y+1=2(x+4) distribute the 2 to get y+1=2x+8 and you then do inverse operation by subtracting the 1 on both sides to get y=2x+7 and the slope intercept form is y=mx+b so that’s why

for number 9 the answer is (0,7) as to find the y-intercept, substitute in 0 for x and solve for y as y+1=2((0)+4) distribute the 2 after doing 0+4 to get y+1=8 inverse operation so subtract 1 to get 7 so that’s why it’s (0,7)

and for 10 the answer is 2x−y=−7

The Direct Variation :

Direct Variation is said to be the relationship between two variables in which one of the variables is multiple of the other variable.

When x is directly proportional to y then the relation can be written as

Rico found a hailstone after a recent thunderstorm and calculated its volume to be 9.2 × 10 gallons, instead of gallons, among the following units the cubic meter would be the most appropriate unit for measuring the volume of Rico's hailstone.

As Rico found a hailstone after a recent thunderstorm and calculated its volume to be 9.2 × 10 gallons.

We know that,

The hailstone is in form of a sphere.

So, the volume of the sphere will be [tex]\left(\frac{4}{3}\right) \pi r^3[/tex]

So, [tex]\text { Volume of hailstone }=\left(\frac{4}{3}\right) \pi r^3[/tex]

From above, we can conclude that,

The unit of volume of hailstone depends on the value of the radius of the hailstone. (As here the other value is 4/3 and [tex]\Pi[/tex] is constant.

The most appropriate unit for measuring the value of the radius of the hailstone is the meter.

From the given table's rate, Jasim's salary for a total of 30 hours worked last week is computed as £286.2.

Given:

Jasim worked 30 hours total last week.

On weekends, he worked 12 of these hours.

From the table given, we can find Jasim's pay for last week.

Number of hours worked by him from Monday to Friday = 30 -12 = 18 hours

His pay from Monday to Friday =  18 × 8.70

                                                    =  £156.6

His pay on weekend = 12 × 10.80

                                   = £129.6

Total pay of Jasim = 156.6 + 129.6

                               = £286.2

Therefore, Jasim's pay for a total of 30 hours worked last week is calculated as £286.2 using the given table's rate.

The positive integers (n) for which the perimeter of sector AOB is greater than 20 are 7, 8, 9 and 10. Also, the positive integer (n) for which the perimeter of sector AOB is less than 30 is 11.

The length of an arc of a circle increases as the sector angle increases, provided that the radius of the circle remains the same. Additionally, the ratio of the length of an arc (arc length) of a circle to the circumference of the circle is equal to the ratio of the sector angle to angle measure of a circle (360°).

By applying this ratio to this circle, we would have the following mathematical expression:

Length of arc AB/Circumference = Sector angle/360°

Rearranging the above mathematical expression, we have:

Length of arc AB = (Sector angle/360°) × Circumference

Note: Circumference = πd = π × 2n = 2πn

Sector angle = 360°/n

Substituting the given parameters into the expression, we have;

Length of arc AB = (360°/n/360°) × 2πn

Length of arc AB = 2π

Next, we would calculate the perimeter of sector AOB:

Perimeter of sector AOB = Length of arc AB + AO + OB

Perimeter of sector AOB = 2π + n + n

Perimeter of sector AOB = 2π + 2n

If the perimeter of sector AOB is greater than (>) 20, the positive integers (n) is given by:

P > 20

2π + 2n > 20

2n > 20 - 2π

n > 10 - π

n > 10 - 3.142

n > 6.858 ≈ 6.9.

Therefore, n = 7, 8, 9, and 10.

If the perimeter of sector AOB is less than (<) 30, the positive integers (n) is given by:

P < 30

2π + 2n < 30

2n < 30 - 2π

n < 15 - π

n > 15 - 3.142

n > 11.858 ≈ 11.9.

Therefore, n = 11.

The domain and range of the of this function C(n) = 120 + 8n, in the context of the situation is 10 ≤ n ≤ 24 and 200 ≤ C ≤ 312 respectively.

The set of inputs a function can accept is referred to as the domain of the function in mathematics. DOM (f) or DOM f, where f is the function, may be used to indicate it.

A function f: X to Y has X as its domain, to put it more precisely. The domain of a function is not a property of it, but rather a part of the definition in contemporary mathematical terminology.

The function f can be represented graphically using the Cartesian coordinate system in the unique situation where X and Y are both subsets of R. A projection of the function's graph onto the graph's x-axis in this instance serves as the domain's representation.

We have given the function C(n) = 120 + 8n where n is no. of children going to trip which must be at least 10 and function C is the total cost trip.

If at least 10 children must go to make the trip possible, then n must be greater than 10 and the total no. of children is 24 which gives us

10 ≤ n ≤ 24, n is restricted between 10 and 24

Also, if n is at least 10, the putting the value in the function C(n) = 120 + 8n gives us

C(n) = 120 + 8(10)

      = 200

Which means C must be greater or equal to 200 but we also take the condition in consideration that all students are going to the trip meaning 24 children is n, which gives us

C(n) = 120 + 8(24)

      = 312

This gives us, 200 ≤ C ≤ 312, that is C is restricted between 200 and 312.
