How many whole numbers are there with not more than 4 digits?I thought the answer is 9999, but it apparently isn't....
Answers
We need to find whole numbers not more than 4 digits
Not more than 4 digits means it can be a one digit, 2 digit, 3 digit and a 4 digit number
It is a whole number so we include 0
-----, ------- , -------, --------
First digit we can use numbers 0 to 9 so 10
For second digit we can use numbers 0 to 9 so 10
For third digit we can use numbers 0 to 9 so 10
For fourth digit we can use numbers 0 to 9 so 10
---10--, ---10---- , --10-----, ----10----
So 10* 10 * 10 * 10 = 10000
10000 whole numbers are there with not more than 4 digits

Slope intercept form:
The equation of straight line is given by:
....[1]
where, m is the rate or slope and b is the initial value of y-intercept.
As per the statement:
A certain species of tree grows an average of 3.1 cm per week.
Let x be the number of week and y represents the weekly height of the tree.
then;
" tree grows an average of 3.1 cm per week." translated to 3.1 x
It is also given that:
the measurements begin when the tree is 400 centimeters tall.
⇒y(0) =b = 400 cm
Substitute the given values in [1] we have;
Therefore, an equation for the sequence that represents the weekly height of this tree in centimeters is,
X for the number of weeks
Y for total CM

The area and perimeter of an isosceles trapezoid with a 60° base angles and bases 9 and 13 is 38.105 squared units and 24 units respectively.
What is area and perimeter of the isosceles trapezoid?
The area of the isosceles trapezoid is the space occupied by it. It can be find out using the following formula,
Permiter of the isosceles trapezoid is the total length of the boundary by which it is enclosed. It can given as,
Here (a,b) are the base side (c) is the side of leg and (h) is the height.
The image of the given isosceles trapezoid is attached below. Let the value of leg is x units. Thus using right angle property the cos theta is,
And the height of this trapezoid is,
Thus the area of the solid is,
The perimeter of the solid is,
Thus, the area and perimeter of an isosceles trapezoid with a 60° base angles and bases 9 and 13 is 38.105 squared units and 24 units respectively.
Learn more about the area of the isosceles trapezoid here;
The other side of each right triangle is such that tan 60° = Heigth / 2
Then height = 2*tan60°.
The area of the trapezoid is height * (base 1 + base 2)/2
Then area = 2*tan (60°) * (13+9)/2 = 38.11
