F(x) is the function that represents a given equation. It is defined more specifically by rules or conditions to satisfy the whole formula/equation.
In this case, f(x) has an inverse proportion with x (e.g. f(x) = 1/x). The second parameter says that f(x) = -15 when x is 30. Given that condition, just look for the formula, among the choices, that will result to -15 when x = 30. The answer is:
D. f(x) = -450/x
This is just -450/30 = -15
Start with
b/4.9=-20.6
Multiply both sides by 4.9 you will be left with b
b=-20.6*4.9
b=-100.94
now to check
-100.94/4.9=-20.6
Susana=s
maria=m
m= 3s/5
s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35
35 --->5/5
x ---> 3/5
x= (3/5)*35 / (5/5)
x=21
edad de maria= 21 años
Answer:
840
Step-by-step explanation:
Given the date:
Birth date = 12/24/2002
Number of digits = 8 = 8! = (8*7*6*5*4*3*2*1) = 40320
Repeated digits :
digit 2 = 4 times = 4! = (4 * 3 *2 * 1) = 24
digit 0 = 2 times = 2! = 2*1 = 2
Therefore the number of 8 digit codes that can be formed is :
8! / (4! * 2!)
40320 / (24 * 2)
40320 / 48
= 840
Hence, 840 8 digit codes can be formed
