Why tan(π/4) = 1 can you explain it simply? Also can we use it with cos, cot, sin, sec and cosec? Thanks! please, please dont write random answers it may be reported.

Answers

Answer 1

Answer:

1) tan π/4 = 1

2) cos π/4 = 0.7071

3) cot π/4 = 1

4) sin π/4 = 0.7071

5) sec π/4 = 1.4142

6) cosec π/4 = 1.4142

Step-by-step explanation:

Angle π is in radians

But converting to degree, it is;

π = 180˚

Thus; π/4 = 180/4 = 45°

Thus;

1) from calculator; tan π/4 = tan 45° = 1

2) from calculator, cos π/4 = cos 45° = 0.7071

3) cot is equivalent to 1/tan

Thus; cot π/4 = 1/(tan π/4) = 1/tan 45 = 1/1 = 1

4) from calculator, sin π/4 = sin 45° = 0.7071

5) sec in trigonometry is equivalent to 1/cos.

Thus;

sec π/4 = 1/cos π/4 = 1/cos 45° = 1/0.7071 = 1.4142

6) cosec in trigonometry is equivalent to 1/sin

Thus;

cosec π/4 = 1/sin π/4 = 1/sin 45° = 1/0.7071 = 1.4142

Answers

80 but I am not for sure

Answer:

1004.8^3

Step-by-step explanation:

to find the volume you must first get the area of the base

3.14 x 8 squared or 8^2 which will equal 200.96

then you multiply the base times height

200.96^2 x 5 = 1004.8 cubed or 1004.8^3

also be careful you don't multiply 200.96 twice because it is squared (;

1. A TV is on sale for $399, or 16% off. What was the original price of the TV? Show your work.
2. A computer is on sale for $450.50, or 15% off. What was the original price of the computer? Show your work.

Answers

Answer:

Step-by-step explanation:

1) $399 = 84% of the original amount

Divide both sides by 84 to get what one percent would be

$4.75 = 1%

Then multiply both sides to get one hundred percent [the original price]

$475 =100%

Use this method to do the second question

$450.50 = 85%

Divide by 85

$5.30 = 1%

Multiply by 100

$530 = original price

Which situation can best be modeled with an exponential function? A.The value of a car depreciating 6% each year. B.The cost to purchase different weights of bananas at a store. C.The total number of miles run by a person who runs 8 miles per day. D.The amount of money a salesperson makes if they make a salary plus 3% commission on total sales for the week.

Answers

Answer:

A.The value of a car depreciating 6% each year.

Step-by-step explanation:

According to definitions.net "The exponential function is used to model a relationship in which a constant change in the independent variable gives the same proportional change in the dependent variable."

Given that the car depereciate by 6% each year, I can write;

Let the initial value of the car be P

Let the value of the car at time t be Y

Let the number of years be t

This is a case of exponential decay so;

Y = P( 1 - 6/100)^t

Which of the following represents “three times the abscissa decreased by the ordinate is twenty-two”?

3 x = 22 - y
y - 3 x = 22
3 x - y = 22

Answers

Answer:

3x - y = 22

Step-by-step explanation:

The abcisssa is known as the x coordinate while the ordinate is the y coordinate

abcissa = x

ordinate = y

“three times the abscissa = 3x

“three times the abscissa decreased by ordinate is expressed as;

3x - y

Is the result is 22, hence;

3x - y = 22

this gives the required expression

HELP WHAT IS THE AREA OF THE COMPOSITE FIGURE

Answers

Answer:

[tex]76 ft^3[/tex]

Step-by-step explanation:

First, split the figure into two different rectangular prisms. I found it easiest to split it like this (image attached below).

To find the volume of the lower prism, multiply the Length (6ft) x Width (2ft) x Height (3ft).

6 * 2 * 3 = 36 [tex]ft^3[/tex]

Next, subtract 3 from 8 to get the height of the top prism. 8 - 3 = 5, so the height of the top prism is 5.

Multiply the Length (4ft) x Width (2ft) x Height (5ft).

4 * 2 * 5 = 40 ft[tex]^3[/tex]

Add the two volumes.

40 + 36 = 76 ft^3.

Final answer: [tex]76 ft^3[/tex]

what is 0.000036÷180 in standard form

Answers

Answer: 36/1000000 is the pq form of the given no..

Step-by-step explanation:

The standard form of 0.000036÷180 is  2 × [tex]10^{-7}[/tex] .

How do you express a number in standard form?

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.23 × [tex]10^{8}[/tex]; If you observe carefully, 1.23 is a decimal number between 1.0 and 10.0 and so we have the standard form of 123,000,000 as 1.23 × [tex]10^{8}[/tex].

According to the question

0.000036÷180 in standard form

Now,

0.000036÷180

= [tex]\frac{0.000036}{180}[/tex]

= 0.0000002

= [tex]\frac{2}{10000000}[/tex]

= 2 × [tex]10^{-7}[/tex] is the standard form .

Hence, the standard form of 0.000036÷180 is  2 × [tex]10^{-7}[/tex] .
