Answer:
6 students at the preschool of four years old attended the full day program.
Step-by-step explanation:
Given:
Number of four years old students = 16
fraction of four years old students attended full day program = 
We need to find the number of four years old students attended the full day program.
Solution:
Now we can say that;
number of four years old students attended the full day program is equal to fraction of four years old students attended full day program multiplied by Number of four years old students.
framing in equation form we get;
number of four years old students attended the full day program = 
Hence 6 students at the preschool of four years old attended the full day program.
Answer:
Step-by-step explanation:
The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5
Answer:

Step-by-step explanation:
where is the question to solve ?
Step-by-step explanation:
(7n − 5) / (2n + 5) approaches 7/2 as n approaches infinity. However, this is an alternating series. So the function is fluctuating between -7/2 and +7/2. So the limit does not exist.
