Answer:
A polynomial needs to have either addition, subtraction or multiplication in the equation.
The 2nd, 3rd and 4th answers have subtraction and addition, so those are polynomials.
The first answer is a fraction, which is a division problem, therefore is not a polynomial.
option B is a one-to-one function
Answer:
b) simplify the constant
c)isolate the variable by dividing the coefficient
Step-by-step explanation:
Since a sphere's surface area is 4πr², we then need to find r as a function of time t, which is 9t (since it increases by 9 every second)+0 (the initial value)=9t. Plugging it in, we get 4π(9t)²=4π*36t²=144πt²
Answer:
A - They Have Too Much Caramel
Step-by-step explanation:
Ari likes 3 oz caramel for 5 scoops ice cream.
Freeze Zone makes 6 oz caramel with 8 scoops of ice cream.
Divide both amounts of Freeze Zone by 2.
6 oz caramel for 8 scoops of ice cream is the same ratio as
3 oz caramel for 4 scoops of ice cream.
Since Ari likes 3 oz caramel for 5 scoops ice cream,
he will think it's too much caramel for the ice cream.
Answer: A - They Have Too Much Caramel
