Answer: ![8.71\ ft](https://tex.z-dn.net/?f=8.71%5C%20ft)
Step-by-step explanation:
Given
Ladder is 16 ft from bottom and 12 away from the base of the wall
In another case ladder is 18 ft above the ground and let say x ft away from the base of the wall
In both the cases the length of ladder remains the same
Using Pythagoras theorem, we can write
![\Rightarrow 16^2+12^2=L^2\ldots(i)\\\Rightarrow 18^2+x^2=L^2\ldots(ii)\\\text{From (i) and (ii)}\\\Rightarrow 16^2+12^2=18^2+x^2\\\Rightarrow x^2=256+144-324\\\Rightarrow x^2=76\\\Rightarrow x=\sqrt{76}\\\Rightarrow x=8.71\ ft](https://tex.z-dn.net/?f=%5CRightarrow%2016%5E2%2B12%5E2%3DL%5E2%5Cldots%28i%29%5C%5C%5CRightarrow%2018%5E2%2Bx%5E2%3DL%5E2%5Cldots%28ii%29%5C%5C%5Ctext%7BFrom%20%28i%29%20and%20%28ii%29%7D%5C%5C%5CRightarrow%2016%5E2%2B12%5E2%3D18%5E2%2Bx%5E2%5C%5C%5CRightarrow%20x%5E2%3D256%2B144-324%5C%5C%5CRightarrow%20x%5E2%3D76%5C%5C%5CRightarrow%20x%3D%5Csqrt%7B76%7D%5C%5C%5CRightarrow%20x%3D8.71%5C%20ft)
<h2>
<u>Answer</u><u>:</u><u>-</u></h2>
Jessica sells = 240 books,
Josh sells = 16 books.
<h3>
Given:-</h3>
The price of one book is = $15
Jessica sold 15 times more books than Josh.
In total, they have sold 256 books.
<h3>Solution:-</h3>
We can easily find the answer using variables.
Let,
Josh sold a total of x books whereas Jessica sold a total number of 15x books.
together they sold 16x books.
So we can form the equation
16x= 256
by solving this equation we will get x=16
So, Josh sold 16 books and Jessica sold 16×15=240 books in total.
Let us use 360 days for the 1 year term.
principal = 1,200interest rate = 8% unless otherwise stated, this rate is per annum or annual rate.term = 240 days
Simple Interest = Principal * interest rate * termS.I = 1,200 * 8% * 240/360S.I = 1,200 * 0.08 * 0.667S.I = 64.032 rounded off to 64
It must be a and c, as these are the only two with four closed sides
y = 650x is an illustration of a linear function
-
The domain of the function is:
- The domain is continuous
The function is given as:
Where:
hours on the clock
Because x represents time, it cannot take a negative value.
So, the domain is
Also:
x can take a whole number or decimal numbers
i.e. You can climb for 3 hours or part of an hour
When a data can take decimal, then such data is continuous.
Hence, the domain is continuous
