Answer:
emissions = 40·0.65^t
Step-by-step explanation:
The decay factor in an exponential equation is 1+(decay rate), so the equation can be written ...
amount = (initial amount)×(decay factor)^t
where the decay factor applies to 1 unit of time t. Filling in the given values, we find ...
decay factor = 1 +(-35%) = 0.65 . . . . for 1 year
emissions = 40×0.65^t . . . . . million tons, for t in years
The answer is D.) 8
Explanation: 10p+5= 18p–6/2
Subtraction Property of equality states that you subtract the same number from both sides of an equation.
Subtract 10p from both sides of an equation
10p+5-10p = 18p-62-10p
Simplify:
5 = 8p -62
Addition Property of equality states that you add the same number from both sides of an equation.
Add 62 to both sides of an equation:
5+62 = 8p -62 +62
Simplify:
67 = 8p
Division Property of equality states that you divide the same number from both sides of an equation.
Divide by 8 in equation [3] ;
Simplify;
p = 8.375 ≈ 8 (approx)
Therefore, the value of p is, 8
Hope this helps :) sorry if wrong and sorry about confusion.
Answer:
(x -2) is a factor
Step-by-step explanation:
The factor theorem tells you that (x-2) is a factor of g(x) if g(2) = 0.
g(2) = 2·2³ -5·2² +2 +2 = 16 -20 +2 +2 = 0
Since g(2) = 0, (x -2) is a factor of g(x).
__
The graph shows us the complete factorization is ...
g(x) = (2x +1)(x -1)(x -2)
