The rule for secants tells you
EC·ED = EB·EA
(x+4)(x+5) = (x+1)(x+12)
9x+20 = 13x+12 . . . . . . simplify, subtract x²
8 = 4x . . . . . . . . . . . . . . add -12-9x
2 = x

choli [55]

Answer: 5040

Step-by-step explanation:

Given : Number of choices to make a four digit code ( 0 to 9)= 10

If repetition is not allowed , then we use Permutations to find the number of different code groups can be designed.

The number of permutations of n things , taking r at a time is given by :-

$^nP_r=\dfrac{n!}{(n-r)!}$

Then, the number of permutations of 10 numbers , taking 4 at a time is given by :-

$^{10}P_{4}=\dfrac{10!}{(10-4)!}\\\\=\dfrac{10\times9\times8\times7\times6!}{6!}\\\\=\dfrac{10\times9\times8\times7}{1}\\\\=5040$

Hence, the number of different code groups can be designed= 5040

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

P is principle amount
r is rate
t is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 9500

r = 4.5% = 0.045

t = 5

Step 2: Find A

Substitute in variables [Simple Interest Rate Formula]: A = 9500(1 + 0.045)⁵
(Parenthesis) Add: A = 9500(1.045)⁵
Evaluate exponents: A = 9500(1.24618)
Multiply: A = 11838.7
