Why are domain restrictions for inverse trigonometric functions necessary?

1 answer:

8 0

<span>A function must be one-to-one for it to have an inverse. As we are sure you know, the trig functions are not one-to-one and in fact they are periodic (i.e. their values repeat themselves periodically). So in order to define inverse functions weneed to restrict the.</span><span>

A scale model of a building is 3 inches tall. If the building is 90 feet tall, find the scale of the model.

olganol [36]

The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

<h3>Scaling of measurement</h3>

Scaling is the way of enlarging or reducing the image of an object.

Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;

Convert both measures to same units

Since 1 feet. = 12 in

90 feet = 90/12 in = 7.5 in

Take the ratio

3 : 7.5 = 30: 75

Reduce to lowest term

30: 75 = 2 : 5

Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

The angles of a triangle always add up to 180°.

By simply adding the angles and checking the total, you can tell if they make a triangle or not.

Using this property, 5 won't make a triangle, 6 will.

Hope this helps! :D

There is a difference between a research topic and a research question. A research question provides a foundation for creating a

True [87]

The research question is important to a researcher as it helps in solving the issue that the researcher wants to solve.

The research topic will be "Social media has an effect on the behavior of children".

The research question will be "what effect does social media has on the effects of the behavior of children".

The null hypothesis will be "there is no statistical significance between social media and children's behavior".

The alternative hypothesis will be "there is a statistical significance between social media and children's behavior".

The null hypothesis will be rejected when the p-value is equal to the significance level or it's less than it.

Bob rolls a fair six-sided die each morning. If Bob rolls a composite number, he eats sweetened cereal. If he rolls a prime numb

hammer [34]

Bob eats a 171 days sweetened cereal and 194 days he eat unsweetened cereal.

According to the statement

we have given that the Bob rolls a composite number, he eats sweetened cereal. If he rolls a prime number, he eats unsweetened cereal.

and we have to find that the expected value of the difference between the number of days.

So, the total number of days in a year is 365 days.

Chance to get a prime number on a die = 3/6

Chance to get a prime number on a die = 1/2.

and chances to get a composite number = 2/6

chances to get a composite number = 1/3

and chances to get a 1 on a die = 1/6.

Then the expected value =

so, expected value = 365(1/6) + 365(1/3) + 365(1/2)

then after calculating

Expected value = 1+2+1

then the value become is 4

and by this way he eat 171 days sweet cereal and other days he eat unsweetened.

So, Bob eats a 171 days sweetened cereal and 194 days he eat unsweetened cereal.
