Which expression helps you find the length x of a side of a rectangle that has a diagonal of 15 units and a width of 9 units?

1 answer:

8 0

A. x^2 = 15^2 - 9^2

Here's why:
c^2 = a^2 + b^2

from the question:
15^2 = 9^2 + x^2

15^2 - 9^2 = x^2 which is similar to answer in A.

Answer:

After 11 weeks, Darnell′s savings account will have a total of $8,360.

Step-by-step explanation:

The data provided is as follows:

n: 1 2 3 4

f (n): 260 360 460 560

Consider the data for f (n).

The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.

The nth term of an arithmetic sequence is:

$a_{n}=\frac{n}{2}[2a+(n-1)d]$

Compute the value of f (11) as follows:

$f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100]$

$=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360$

Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.
