Answer:
x = 19
Step-by-step explanation:
A quadratic function is a function that has a degree of 2. This shows that there will be about 72 births for month 8
<h3>Quadratic functions</h3>
A quadratic function is a function that has a degree of 2. Given the quadratic function shown:
f(x) = x² + x
where
x is the total months
In order to use the function to predict the number of births for month 8, we will substitute x = 8 into the function as shown:
f(x) = x² + x
f(8) = 8² + 8
f(8) = 72 births
This shows that there will be about 72 births for month 8

Answer:
$265
Step-by-step explanation:
We can use the simple interest formula for this:
<em>P = initial balance</em>
<em>r = annual interest rate</em>
<em>t = time</em>
<em />
First, change 4% into its decimal form:
4% -> 
-> 0.04
Next, we need to change the annual interest rate to 1.5 since 18 months is 1.5 years. Now plug in the values:
Eugene owes $265 of interest.
Answer: has a maximum
the maximum is 11
Step-by-step explanation:
f(x)= -5x^2-10x+6
the function f(x)= ax^2+bx+c=0 has a<0 so the equation has a maximum
I know V has the coordonate x=-b/2a, and y=-(b^2-4ac)/4a
b^2-4*a*c= (-10)^2-4*(-5)*6=100+120=220
so -b/2a=-(-10)/-2*5=+10/-10=-1 and
-(b^2-4ac)/4a=-220/4*(-5)=-220/-20=22/2=11
so V( -1, 11)
and the maximum is 11
