The total pay Tom earn for working 11 hours is £185

Given that Tom is paid £15 if he works for less than 7 hours and then paid 1 1/3 times his normal salary if he works more than 7 hours.

Given that he works for 11 hours, hence:

Pay for the first 7 hours = £15 × 7 hours = £105

Pay for the overtime = 1 1/3 × £15 × (11 - 7) = 4/3 × £15 × 4 = £80

Total pay = £80 + £105 = £185

Hence the total pay Tom earn for working 11 hours is £185

Answer:(a) To find the population after 1 year, we can simply plug in t = 1 into the given equation and evaluate:

P(1) = 242,700e^(0.25*1) = 278,926.38

Therefore, the population after 1 year would be approximately 278,926.

(b) We want to solve for the time t when the population P(t) reaches one million. In other words, we want to find t such that:

P(t) = 1,000,000

Substituting the given equation for P(t), we get:

242,700e^(0.25t) = 1,000,000

Dividing both sides by 242,700, we get:

e^(0.25t) = 4.120439

Taking the natural logarithm of both sides, we get:

0.25t = ln(4.120439)

Solving for t, we get:

t = (ln(4.120439))/0.25 ≈ 7.77 years

Therefore, it will take approximately 7.77 years (rounded to two decimal places) for the population to reach one million.

The period of the given trigonometric function is: 20.

The distance between the repetition of any function is called the period of the function. For a trigonometric function, the length of one complete cycle is called a period.

Sine and cosine functions start repeating the same pattern of y-axis values after every 2(pi). The period is defined as just the distance on the x-axis before the pattern repeats.

Now, looking at the trigonometric graph, we see that the x-interval for which the graph repeats itself is 20

Step-by-step explanation:

Answer:

\(g(x) + h(x) = x^3 + 6x + 5\)

Step-by-step explanation:

We are told that:

\(g(x) = x^3 + 5x\)

\(h(x) = x + 5\),

and we are asked to find an expression for \(g(x) + h(x)\).

In order to find the expression for  \(g(x) + h(x)\), we have to simply add the expressions of \(g(x)\) and \(h(x)\) together:

\(g(x) + h(x)\)

= \(x^3 + 5x + x + 5\)

= \(x^3 + 6x + 5\)

Answer:

80

Step-by-step explanation:

t is important to note that a square of any non-zero integer is positive, and therefore there is no advantage in using negative integers instead of positive integers to attain the greatest difference of squares. So we will not consider negative integers.

The greatest value of a^2 - b^2 occurs when a^2 is at its largest and b^2 is at its smallest.

The larger a, the larger a^2:

8 ^ 2 = 64

9 ^ 2 = 81

10 ^ 2= 100

Since a^2 can have at most two digits, a=10 is too large, and so a=9 is the largest integral value of a we can use.

Now, b^2 is at its smallest when b is closest to zero on the number line (the further b gets from zero, the larger its square becomes):

2 ^ 2 = 4

1 ^ 2 =1

0 ^ 2 = 0

Remember to go back to the original problem sometimes, to make sure you are taking everything into account. It states b doesn't =0, and therefore the b=1 is the closest b can get to zero as an integer. So, the greatest difference between b^2 and a^2 is when b=1 and a=9, giving the result:

a^2-b^2 =9^2-1^2 =81-1= 80.

So, 80 is your answer.

The total paving cost would depend on the specific measurements and dimensions of the section, which are not provided in the question. Therefore, the exact total paving cost cannot be determined without this information.

The question describes a series of fractional divisions of a section, but it does not provide any numerical values for the measurements. Without knowing the actual dimensions or the area of the section, it is impossible to calculate the total paving cost.

The cost per square foot is given as $2.25, which would need to be multiplied by the area of the section to determine the total cost. However, since the measurements are not provided, a precise answer cannot be given.

The area of the rhombus is 18 square units. And the perimeter of the rhombus is 48 units.

What is rhombus ?

A rhombus is a type of quadrilateral in which all four sides are of equal length. It is a special case of a parallelogram in which the opposite sides are parallel and the adjacent sides are congruent. A rhombus has four vertices and four angles, and the opposite angles are equal. The diagonals of a rhombus bisect each other at right angles, which means they divide the rhombus into four congruent right triangles. The area of a rhombus can be calculated as the product of the lengths of its diagonals divided by 2.

To find the area and perimeter of a rhombus with side lengths of 12 and 6 and an altitude of 3, we need to use the formula for the area and perimeter of a rhombus.

The area of a rhombus can be found using the formula:

Area = (base x height)/2

where the base is the length of one side of the rhombus and the height is the length of the altitude.

In this case, the base of the rhombus is 12 and the height is 3, so we can plug those values into the formula and get:

Area = (12 x 3)/2 = 18 square units.

Therefore, the area of the rhombus is 18 square units.

To find the perimeter of a rhombus, we use the formula:

Perimeter = 4 x length of one side

In this case, the length of one side is 12, so we can plug that value into the formula and get:

Perimeter = 4 x 12 = 48 units.

Therefore, the perimeter of the rhombus is 48 units.

The area of the given  isosceles triangle is 480 square units.

Isosceles triangle:

An isosceles triangle is a triangle with two sides of equal length. Let's do a little activity to understand this better. Take a square piece of paper and fold it in half. Draw a line from the folded top corner to the bottom edge (see image below). Open the sheet and you will see a triangle. Mark the triangle vertices as O, D, C. Then measure OD and OC. Repeat this activity at different scales and observe patterns. We can see that OD and OC are always the same. A triangle with two equal sides is called an isosceles triangle.

Given,

base (b) = 20 units and

height (h) = 120 units.

The formula to calculate the area is 1/2 × b × h square units.

By substituting the values, we get

⇒ Area = 1/2 × 20 × 120

            = 480 unit Squares

Therefore, the area of the given  isosceles triangle is 96 square units.

The equation for the tangent to the graph of y = arcsin(x/2) at the origin is y = x. This means that for any given x-value, the corresponding y-value is equal to that x-value, creating a line with a slope of 1. This line is tangent to the graph of y = arcsin(x/2) at the origin, which is (0, 0).

To find the equation for the tangent to the graph of y = arcsin(x/2) at the origin, we must first find the slope at the origin. We can do this by taking the derivative of the function y = arcsin(x/2) with respect to x.

The derivative of

y = arcsin(x/2) with respect to x is y' = (1/2)cos(x/2).

At the origin, x = 0, so the slope of the tangent at the origin is

y' = (1/2)cos(0) = 1.

Therefore, the equation for the tangent to the graph of

y = arcsin(x/2) at the origin is y = x, which has a slope of 1.

Answer:

Step-by-step explanation: Find the y-intercept. Write the equation in slope-intercept form. Write an equation of the line that passes through each pair of points. 5. (4, −3), (2, 3)

y=6x+6 is the function representing the line that includes the points (2,18) and (5,36).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are (2,18) and (5,36).

m=36-18/5-2

=18/3=6

slope of line is 6.

Now we need to find the equation of line passing through (2,18) and (5,36).

We need to find the y intercept.

18=6(2)+c

18=12+c

18-12=c

6=c

So y intercept is 6

The equation of line is y=6x+6

Hence y=6x+6 is the function representing the line that includes the points (2,18) and (5,36).
