Answer:
Step-by-step explanation:
f(x) = (x + 2)(x +6)
1) The function is positive for all real values of x where x > –4 :
COUNTER-EXAMPLE : x = - 3 you have -3>-4 but (-3+2)(-3+6) = -1 ×3 =-3 no positive .
2) The function is positive for all real values of x where
x < –6 or x > –3.
COUNTER-EXAMPLE : x = - 2.5 you have -2.5>-3 but (-2.5+2)(-2.5+6) = -0.5 ×3.5 =-1.75 no positive .
same method for the statement : "The function is negative for all real values of x where
x < –2."
conclusion : statement about the function is true: "The function is negative for all real values of x where
–6 < x < –2."

Answer:
He should pay 30 quarters
Step-by-step explanation:
To find the number of quarter dollars he should pay, first calculate out the amount of money this would cost. For this, we can multiply the cost of the item by the number of them that we got and then add them all together.
Burgers
2 * 1.75 = 3.50
Cake
2 * 1.50 = 3.00
Soda
1 * 1.00 = 1.00
Total
3.50 + 3.00 + 1.00 = 7.50
Now to find out how many quarters he should pay, we divide the amount by .25.
7.50/.25 = 30
The value that remains under the radical is 2
<h3>How to determine the value under the radical?</h3>
The correct expression in the question is:
1250^4
This can be rewritten as:
Express 1250 as product
Expand the expression
Simplify
Evaluate the product
Hence, the value that remains under the radical is 2

Answer:
Step-by-step explanation:
pi^3 is about 30. (3 * 3 * 3 get's you to 27. The 0.14 will make a bit more)
pi^2 is about 10 (3^2 = 9. You need only get an approximate answer)
pi/4 = about 0.75 I'm using 3 to be the value of pi. That's close enough to get an answer.
pi/8 = 3/8 which is about 0.375 which is the smallest one.
