Answer:
The average age was minimum at 1954 and the average age is 25.5.
Step-by-step explanation:
The given quadratic function is
It models the median, or average, age, y, at which men were first married x years after 1900.
In the above equation leading coefficient is positive, so it is an upward parabola and vertex of an upward parabola, is point of minima.
We need to find the year in which the average age was at a minimum.
If a quadratic polynomial is 
, then vertex is
54 years after 1900 is
Substitute x=54 in the given function.
Therefore, the average age was minimum at 1954 and the average age is 25.5.
Answer: <
Explantion:
, because you factor the 5 into 10 and 4 so
The second one you want will be integers.
the absolute value of the product of the zeros of a is 
.
<u>Step-by-step explanation:</u>
Here we have , 
is a polynomial function of t, where k is a constant. Given that a(2) = 0 . We need to find the absolute value of the product of the zeros of a . Let's find out:
Equation every factor of a(t) to zero we get:
⇒ 
⇒ 
⇒ 
But , t=2 So , 
. Now , the absolute value of the product of the zeros of a is :
⇒ 
⇒ 
⇒
Therefore, the absolute value of the product of the zeros of a is .
4+5 and 5+4 because they use the same numbers but just reversed
Answer:
x=19
Step-by-step explanation:
Set both equal to each other and then solve for x
