The same way you tell if a parabola opens up or down, by the leading coefficient of the variable.

Step-by-step explanation:

Since the x-axis is positive to the right, a positive leading coefficient (3) means it opens to the right. eg. And a negative leading coefficient (-2) means it opens to the left.

The company has decided to redesign the box it uses to hold one dozen donuts, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).

The circumference is the distance around the edge of a circle or any circular object. It is calculated using the formula:

C = 2πr

To find the circumference of a donut, we need to first find the diameter. The diameter of each donut is 3 inches, so the radius is 1.5 inches. The circumference can then be found using the formula:

C = 2πr

where C is the circumference and π is approximately 3.14.

Substituting the radius, we get:

C = 2π(1.5) = 3π

Therefore, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).

The total meters in the wall which is build by a construction company at a rate of 30 cm of the wall per minute, is 16 meters.

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,

W=1/n

A construction company is building a wall. The company can build 30 cm of the wall per minute. In 40 minutes the total cm of wall build by company is,

n=40/30

n=1200 cm

n=12 m

After 40 minutes, three fourth of the wall is completed, which is equal to the 12 meters. Thus, the total meter of the wall is,

(3/4)x=12

x=(12x4)/3

x=16 m

Thus, the total meters in the wall which is build by a construction company at a rate of 30 cm of the wall per minute, is 16 meters.

Answer:

The graph is symmetric about the origin.

The graph does not pass through the origin.

Step-by-step explanation:

We're given:

Because a = 1, then the given function can be rewritten as y = n.

The function y = n will produce a horizontal line. Any function in the form of y = a single number, such as 4 or 9.3 will produce a horizontal line.

This is true, given the graph is a horizontal line.

This is also true. We're given that n is an odd number. The graph will only pass through the origin if n = 0, and 0 is even.

This would only be true when n = 0, and this isn't possible. So, no.

Answer:

B: The graph is symmetric about the origin

First find out what tan45 means then what sin30 means so tan45=1 and sin30=0.5, 1/0.5=2

The evaluation tan45°/sin30° is 2.

The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.

The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.

The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.

given that  tan45°/sin30°

Since   tan45° is 1 and sin30°  is 0.5 so

By that 1/0.5 which comes out as 2.

The total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The total surface area of a cone is given by its curved surface area plus area of its base.

Total surface area = curved surface area + area of base

Total surface area = πrl + πr²

Given that;

Total surface area = πrl + πr²

Total surface area = ( π ×  5cm × 9cm ) + ( π × (5cm)² )

Total surface area = 45πcm² + 25πcm²

Total surface area = 70πcm²

Therefore, the total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².
