Ask your parents about it if they didn't help you can copy mine,
Well I asked my parents about they told me that around their age there weren't lots of facilities they even rarely saw transportation facilities like cars and bikes there were no proper internet facilities e.t.c
When I said them what were the changes in the last 25 years they said there were drastic changes including social, economic, science, transportation, health e.t.c and many more
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
Preston have to get some correct and some incorrect answers.
Answer: The correct answer is Volume Cone = one-third pi t squared k
Step-by-step explanation: The first important detail to note here is that both cylinder and cone have the same base and the same height This implies that when writing out the formula for calculating the volume of either of the two shapes, the radius and the height will be the same number or value.
The volume of a cylinder is given as;
Volume cylinder = pi x r squared x h (that is πr²h)
Also the volume of a cone is given as;
Volume cone = one-third x pi x r squared x h (that is 1/3*πr²h)
However, the variables have been changed such that the radius r is now represented by t while the height h is now represented by k.
Therefore the volume of the cone should now be re-written as;
Volume cone = one-third pi t squared k <em>(that is 1/3 *πt²k)</em>
Answer:
The result after adding a set of numbers or is called a sum.
Step-by-step explanation:
Consider the provided information.
The four mathematical operations are:
![+,-,\times ,\div](https://tex.z-dn.net/?f=%20%2B%2C-%2C%5Ctimes%20%2C%5Cdiv)
The sign + is used to add numbers.
The sign - is used to subtract the numbers.
The sign × is used for the product of the numbers.
The sign ÷ is used for division of the numbers.
When we add two or more number by using the operator + the obtained number or value is called the sum of the numbers.
For example:
Consider the number: 2 + 5 if we add the number the resulting value will be 7.
The number 7 is the sum of 2 and 5.
Thus, the result after adding a set of numbers is called a sum.
