Answer:
x = 6
Step-by-step explanation:
Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is
= 
( cross- multiply )
x(x - 4) = 12 ← distribute left side
x² - 4x = 12 ( subtract 12 from both sides )
x² - 4x - 12 = 0 ← in standard form
(x - 6)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 2 = 0 ⇒ x = - 2
However, x > 0 , thus x = 6
Answer:
no proportional.if it was proportional it would start at (0,0)
Answer:
50mm
Step-by-step explanation:
use pythagorean theorem. sqrt(14^2+48^2)=50
For this case we have the following function:
Where,
A0: initial population
K: rate of change
t: time in years
Substituting values we have:
For the year 2015 we have:
Answer:
the predicted population in 2015 is:
19,807
The probability of a dime is 66% or 2 in 3 or 2:1
