Answer:
36 miles
Explanation:
Let's go ahead sketch the given problem as shown below;
From the above diagram, we can go ahead and determine x, which is the distance the eastbound plane has traveled, using the Pythagorean theorem;
![\begin{gathered} 39^2=x^2+15^2 \\ 1521=x^2+225 \\ x^2=1521-225 \\ x=\sqrt[]{1296} \\ x=36\text{miles} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2039%5E2%3Dx%5E2%2B15%5E2%20%5C%5C%201521%3Dx%5E2%2B225%20%5C%5C%20x%5E2%3D1521-225%20%5C%5C%20x%3D%5Csqrt%5B%5D%7B1296%7D%20%5C%5C%20x%3D36%5Ctext%7Bmiles%7D%20%5Cend%7Bgathered%7D)
Answer:
f(n) = 4 +n
Step-by-step explanation:
We assume you want a function that tells the total number of tiles in figure N.
There are 4 triangular tiles in each figure. The number of square tiles is equal to the figure number (n). So, the total number of tiles in figure n is ...
f(n) = 4 +n
I am gonna do what you did to me and say its easy.
Answer:
Step-by-step explanation:
Part A
The function representing the amount of money in account A after x years is represented by the function
f(x) = 9,628(0.92)x
The amount of money in account A is decreasing by 8% per year.
Part B
The table showing the amount g(r), in dollars, of money in account B after r years with number of years given as 1 2 3 4 and amount in dollars) 1,375 1,512.50 1,663.75 1,830.134.
Looking at the table,
The change per year is
(1512.5 - 1375)/1375 = 137.5/1375 = 0.1
The percentage change is 0.1× 100 = 10%
The amount in account B increases by 10%
Therefore, account B recorded a greater percentage change in amount of money over the previous year since the change in account B is 10℅ which is greater than 8% in account B
