Answer:
This implies the value of x lies between 2,-6
but it doesnot equal to 2,-6
x€(2,-6)
you can observe that ,they are open brackets
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 .
Answer:
Step-by-step explanation:
10 students participated in a Mathematics quiz. If the number of girls is 4 more than the number of boys, find the number of boys and girls who took part in the quiz
Solution: Number of girls = x
Number of boys = y
x + y = 10 -------------------(I)
Number of girls is 4 more than the number of boys
x - y = 4 ----------------------(I)
x = 4 + y
Substitute x = 4 +y in equation (I)
4+ y + y = 10
4 + 2y = 10
2y = 10-4
2y= 6
y = 6/2
y = 3
Plug in y = 3 in eqution (I)
x + 3 = 10
x = 10 - 3
x = 7
Number of girls = 7
Number of boys = 3
Hope this helps :) good luck!!!
