Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

here, we have.

tan∅/(1+ sec∅)

=(sin∅/cos∅)/(1+ sec∅)                  [tan∅=(sin∅/cos∅)]

=(sin∅/cos∅)/(1+1/cos∅)

=sin∅/1+cos∅

multiplying both numerator & denominator by 1-cos∅, we get,

=sin∅(1-cos∅)/ sin^2∅

=(1-cos∅)/sin∅

=cosec∅ - cot∅

The scenarios can you reverse the dependent and independent variables while keeping the interpretation of the slope meaningful in

E) As the number of calls made by a cell phone increases, the cell phone bill amount increases.

We anticipate that independent variables will have an impact on dependent variables. What occurs as a result of the independent variable is referred to as a dependent variable.

Given:

We can see from Option A that the opposite may not be true, as an increase in the risk of lung cancer may not always be accompanied by an increase in the number of cigarettes smoked each day.

Now, second it is clear that the opposite may not be true because an infant's age may not necessarily increase along with his or her height.

Now, third also acknowledges that a rise in traffic is not always accompanied by an increase in pollution in a city.

Fourth, a rise in water density does not always imply an increase in the amount of salt present in the water.

The equation of the perpendicular bisector of the line segment joining (-2, -9) and (-6, 7) is y = (-1/4)x - 2

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,

The midpoint of the line segment joining (-2, -9) and (-6, 7) can be found using the midpoint formula:

Midpoint = ( (x₁+x₁)/2 , (y₁+y₁)/2 )

Midpoint = ( (-2-6)/2 , (-9+7)/2 )

Midpoint = (-4,-1)

Next, we need to find the slope of the line joining the two points (-2, -9) and (-6, 7). We can do this using the slope formula:

Slope = (y₂ - y₁) / (x₂ - x₁)

Slope = (7 - (-9)) / (-6 - (-2))

Slope = 4

The slope of the line perpendicular to the line segment is the negative reciprocal of the slope of the line joining the two points. So the slope of the perpendicular line is -1/4.

Using the point-slope form of a line, the equation of the perpendicular bisector can be written as:

y - y₁ = m(x - x₁), where (x₁, y₁) is the midpoint and m is the slope of the line.

Plugging in the values we found, we get:

y - (-1) = (-1/4)(x - (-4))

y + 1 = (-1/4)(x + 4)

y + 1 = (-1/4)x - 1

y = (-1/4)x - 2

Therefore, the equation of the perpendicular bisector of the line segment joining (-2, -9) and (-6, 7) is y = (-1/4)x - 2.

Answer: To find the limit of the expression 3√x-1/x-1 as x approaches 1, we can use L'Hopital's Rule. L'Hopital's Rule is a method for finding the limit of indeterminate forms, such as 0/0 or ∞/∞, by taking the derivative of the numerator and denominator.

In this case, the expression is of the form 0/0, so we can use L'Hopital's Rule:

lim 3√x-1/x-1 = lim (3/2)((x-1)^(1/2)) / 1 = 3/2

So the limit of the expression 3√x-1/x-1 as x approaches 1 is equal to 3/2.

The quadrilateral is most specifically a square since all the sides of the quadrilateral are equal and have 90°

A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

Given data ,

Let the quadrilateral be represented as ABCD

Now , the measures of the sides of the quadrilateral are

The measure of side AB = measure of side BC

A fraction is a mathematical concept that can be used to express a portion of a whole or a number that can be written as the ratio of two integers.

here,
To divide the 2 cakes equally among 7 people, we can use division. We can think of the total amount of cake as 2 whole cakes or 2/1 cakes. To find out how much cake each person can have, we can divide the total amount of cake by the number of people:

2/1 cakes ÷ 7 people = 2/1 × 1/7 = 2/7 cakes per person

What exactly is speed?

The definition of speed is:

The pace at which an object's location changes in any direction.

Speed is defined as the ratio of distance travelled to time spent travelling. Because it has just one direction and no magnitude, speed is a scalar number.

Formula for Speed

The speed formula is shown below:

s=d/t

Where,

s is the speed in metres per second, d is the distance travelled in metres, and t is the duration in seconds.

Now,

As given petra jogs 60 miles in 110 minutes

In this problem, the cylinder has a diameter of 6 centimeters, which means the radius is 3 centimeters. The area of the base of the cylinder is therefore:

B = πr²

B = π(3 cm)²

B = 9π cm²
