The ending balance if the amount is compounded continusoly is $6,244.84

The interest earned is $4,244.84.

If an amount is compounded continuously, it means that both the amount invested and the interest earned increases in value infinitely over the investment period.

The formula for calculating future value when there is continuous compounding is : A x e^r x N

Where:

Interest = future value - amount invested

2000 x e^0.04 x 3 = $6,244.84

Interest = $6,244.84 - $2000 = $4,244.84

Step-by-step explanation:

If a company is expanding its team at a rate of 10% per year, and it currently has 200 members of staff, we can calculate the number of staff after 1 year using the formula:

number of staff after 1 year = 200 + (10/100) * 200

number of staff after 1 year = 200 + 20

number of staff after 1 year = 220

So, there will be 220 members of staff after 1 year if there are initially 200 members of staff.

The arrow diagram that represents a mapping include the following: arrow diagram C.

The domain of this arrow diagram is equal to {a, c, d}

The range of this arrow diagram is equal to {q, r, s}.

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined.

This ultimately implies that, a domain is the set of all possible input numerical values (x-values) to a function and the domain of a graph comprises all the input numerical values (real numbers) which are located on the x-coordinate.

In this scenario, we can reasonably infer and logically deduce that only the above mentioned relation (arrow diagram C) represents a function because each input variable (domain) has exactly an output variable (range) as illustrated in the diagram.

The value of x is 76°. The solution has been obtained using the properties of hexagon.

What is a hexagon?

A closed, two-dimensional, six-sided polygon in geometry is called a hexagon. It has six vertices, which together create six internal angles, and six line segments. The total of a hexagon's internal angles is 720°.

We know that sum of angles on a straight line is 180°.

So, on the first line with angle 60°, the other angle will be

180° - 60° = 120°

Similarly, on the second line with angle 64°, the other angle will be

180° - 64° = 116°

Similarly, on the third line with angle 36°, the other angle will be

180° - 36° = 144°

Similarly, on the fourth line with angle 48°, the other angle will be

180° - 48° = 132°

Similarly, on the fifth and sixth lines with angle x°, the other angles will be

180° - x° = (180-x)°

We know that sum of angles of interior angles of a hexagon is 720°

Therefore,

⇒ 120° + 116° + 144° + 132° + (180-x)° + (180-x)° = 720°

⇒ 512° + 180° - x° + 180° - x° = 720°

⇒ 872° - 2x° = 720°

⇒ 2x° = 152°

⇒ x = 76°

Hence, the value of x is 76°.

The solution to the expression with decimals rounded to the nearest tenth is: -2

Examine the hundredth number to round the decimal number to the nearest tenth. If the number is more than 5, multiply it by one. If it is less than 5, leave the tenth place value alone and eliminate any numbers after the tenth. 4.624, for example, is 4.6 rounded to the closest tenth.

Thus, given the expression:
2.29 + 9.11 + 15.381 - 5.414 - 7.631.11 + 5.99 - 5.734 + 6.893 - 18.355 -4.411

We first round them up to the nearest tenths is:

2.1 + 9.1 + 15.4 - 5.4 - 7.6 + 6.0 - 5.7 + 6.9 - 18.4 - 4.4  = -2

Thus, it is correct to state that the version of the above-given expression resolved to the nearest tenths (2.1 + 9.1 + 15.4 - 5.4 - 7.6 + 6.0 - 5.7 + 6.9 - 18.4 - 4.4) = -2

If the ratio of profit shares is 3:7:9, then the total profit yield is 38000.

What is ratio?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

The share of Juma's profit is = 3

The share of Ali's profit is = 7

The share of Hassan's profit is = 9

The ratios can be written as 3x : 7x : 9x

The amount of money Juma received is = 6000

The equation for Juma's profit is -

3x = 6000

x = 6000/3

x = 2000

So, the value for Ali's profit -

7x = 7 × 2000

= 14000

The value for Hassan's profit -

9x = 9 × 2000

= 18000

Now, the total profit is represented by the equation -

= 3x + 7x + 9x

= 6000 + 14000 + 18000

= 38000

Therefore, the total profit is 38000.

The required of the sidewalk to the nearest square foot is 13.14 ft².

The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the sum of its length and breadth.

A circle's area is the area that it takes up in a two-dimensional plane. It can be simply calculated using the formula A = r2, (Pi r-squared), where r is the circle's radius. The square unit, such as m2, cm2, etc., is the unit of area.

We have,

Length = 5 ft, width = 2 ft, Radius of circle = 2 ft

Now,

Area of sidewalk = area of rectangle + area quadrant

Area of sidewalk = (5×2) + π(2)^2/4

Area of sidewalk = 10 + 3.14

Area of sidewalk = 13.14 ft²

Note that the figure with an angle of 300° on a circle in standard position is: "An angle in standard position with the terminal side at two-thirds of a full revolution counterclockwise." (Option D)

A standard position angle is one measured counterclockwise from the positive x-axis in a coordinate plane.

This signifies that the angle's starting side is on the positive x-axis, while the angle's terminal side is in the first or fourth quadrant. The angle's vertex is placed at the origin.

Angles are commonly measured in degrees or radians, with a full rotation being comparable to 360 degrees or 2 radians. Angles may now be readily graphed and compared to one another in a coordinate plane.

According to the information ∠1 and ∠2 are complementary to each other.

∠1 ⊥ ∠2
Since PR is parallel to VO and RO is parallel to PV, it follows that PR is congruent to RO. This means that ∠1 and ∠2 are supplementary angles and thus, complementary.
Since PR // VO and RO // PV, then by the Transitive Property of Congruence, VO // PV.

Since PR ≅ RO and VO // PV, then by the Corresponding Angles Postulate, ∠1 ≅ ∠2.

Since ∠1 and ∠2 are congruent, then by the definition of complementary angles, ∠1 and ∠2 are complementary.

Thus, ∠1 and ∠2 are complementary.

∴ ∠1 and ∠2 are complementary
