The simplified form of sine of x over the quantity 1 plus cosine of x (end quantity)  is 1. Option D

The question can be interpreted as sin(x) / (1 + cos(x))

sin(x) / (1 + cos(x)) = (sin(x) / cos(x)) / (1/cos(x) + cos(x)/cos(x))

                      = tan(x) / (1 + sec(x))

                      = (sin(x)/cos(x)) / (cos(x)/(cos(x)+1))

                      = (sin(x)/cos(x)) / ((cos(x)+1)/cos(x))

                      = sin(x) / (cos(x) + 1)

Therefore, the simplified form of sin(x) / (1 + cos(x)) is:

sin(x) / (1 + cos(x)) = sin(x) / (cos(x) + 1) = 1

Hence, The simplified form of sine of x over the quantity 1 plus cosine of x (end quantity)  is 1

Step-by-step explanation:

if you multiply -0.75, times 4 it equals -3 so do that until you get the ninth term. (Multiply each term by 4).

The inverse of the sine can be calculated by using the formula sin^-1(x) = arcsin(x)

To calculate the inverse sine (sin^-1) of a value, you can use a scientific calculator or look up the value in a trigonometric table. However, if you want to understand how to do it manually, follow these steps:

Make sure the value you are calculating the inverse sine of is between -1 and 1, inclusive. If it is not, the inverse sine is undefined.

Write down the value you want to find the inverse sine of.

Use the formula: sin^-1(x) = arcsin(x), where x is the value you wrote down.

Substitute the value of x into the formula and calculate the inverse sine using a calculator or by using a series expansion or Taylor series approximation.

The inverse sine function returns a value in radians, so you may need to convert it to degrees if that's the unit you're working with.

The temperature at half past eleven would be 2 °C.

In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.

Given is that the temperature in Austria one morning was -5 degrees Celsius at eight o clock and increased by 2 degrees Celsius every hour until twelve o clock.

We can write the temperature variation as a function of hour {x} as -

T{x} = (- 5 + 2{x})°C

For half past eleven, we will have -

{x} = 3.5

So, we can write -

T{x} = (- 5 + 2 x 3.5)°C

T{x} = 2 °C

Therefore, the temperature at half past eleven would be 2 °C.

m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.

To determine the unknown angle measures of △DEF, we can use the fact that the sum of the angles of a triangle is 180°. Thus, if we know two angle measures in the triangle, we can use them to calculate the third.

Let's denote the two known angle measures as m∠D and m∠F. We can use the following equation to solve for the unknown angle measure:

m∠D + m∠F + m∠E = 180°

We can rearrange the equation to solve for m∠E:

m∠E = 180° - m∠D - m∠F

Therefore, once we know the measures of m∠D and m∠F, we can calculate the measure of m∠E.

For example, if m∠D = 40° and m∠F = 65°, then the measure of m∠E would be:

m∠E = 180° - 40° - 65° = 75°

Therefore, m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

Hugh made 110 kilograms of 9.1% salt solution.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Hugh poured 100 kilograms of water into 10 kg of salt.

So, the total mass is the sum of the mass of water and the mass of salt.

Thus, 100+10=110 kg.

The ratio between the mass of the salt (10 kg) and the combined mass of the mixture is the concentration.

Now, C=10/110 ×100

= 100/11

= 9.1%

Therefore, Hugh made 110 kilograms of 9.1% salt solution.

Answer:The width of the rectangle is 1 unit

Step-by-step explanation:Let the length of the rectangle be x

let the breadth be x-5

Since ,area of rectangle=length*breadth

           area = x*(x-5)

           6=x^2-5x

           x^2-5x-6=0

solving the above equation,

x^2-(6x-x)-6=0

x^2-6x+x-6=0

x(x-6)+1(x-6)=0

(x-6)(x+1)=0

x=6 and x=-1

since the breadth cannot have negative value

1km/5min (jogging)

4km/5min (cycling)

30÷5= 6

4×6= 24km

Distance covered during riding is 24 km.

Speed of an object is defined as the rate of change of the distance travelled.

Here,

Speed is the distance travelled in a given time.

Total time given, t = 45 minutes

Time taken for jogging, t₁ = 15 minutes

So, time taken for riding, t₂ = t - t₁

t₂ = 45 - 15

t₂ = 30 minutes

Distance covered during jogging, d₁ = 3 km

Therefore speed of jogging, v₁ = d₁/t₁ = 3/15

v₁ = 0.2 km/min

So, speed of riding, v₂ = 4v₁ = 4 x 0.2

v₂ = 0.8 km/min

Therefore distance covered during riding, d₂ = v₂ x t₂

d₂ = 0.8 x 30

d₂ = 24 km

Distance covered during riding is 24 km.

The measure of the arc is option (c) 140°

In geometry, an arc is a curved line that is a part of a circle's circumference. The measure of an arc can be calculated using the angle of the arc, which is measured in degrees.

In the case of EBC, the measure of the arc is 140°. This is because we can use the Angle-Side-Angle (ASA) congruence theorem, which states that two triangles are congruent if and only if two angles and the included side are equal.

In the case of EBC, we know that angle A equals 40° and angle C equals 90° so the only variable left is the measure of the arc, which is equal to 140°.

Therefore, the measure of EBC is 140°. This can be verified by drawing the triangle and measuring the arc with a protractor.

Therefore, option (c) is the right one.

Answer:

x = 3, y = 4

Step-by-step explanation:

3x + y = 13

5x - 2y = 7

To solve by substitution, you solve one of the equations for a variable, and then plug it into the other equation.

I'm going to choose to solve the first equation for y, as that will be the easiest.

y = -3x + 13 (subtract 3x from both sides)

Now we plug this equation into the y in the second equation and solve for x.

5x - 2(-3x + 13) = 7 (distribute)

5x + 6x - 26 = 7 (combine like terms)

11x - 26 = 7 (add 26 to both sides)

11x = 33

x = 3

Now that we know x is 3, we can plug it in a solve either equation for y.

y = -3(3) + 13

y = -9 + 13

y = 4

The amount in the account after 10 years is $4,978.365.

Interest is the sum of money that must be repaid on a loan or received in exchange for a loan. Principle refers to the borrowed or lent funds. The Amount is the total of the principal plus interest. The term "rate of interest" refers to the rate at which interest is applied to the principal.

Given:
