F(1) = -5(1)^2+2(1)+9 = 6
f(2) = -5(2)^2+2(2)+9 = -9
So, because f(1) = 6 is positive and f(2) = -9 is negative, f(1) > f(2).
f(1) is greater than f(2)!
Answer:
A = 143.2
Step-by-step explanation:
A= πr² = π(6.75)² =
× 45.5625 = 143.196 ≈143.2
Answer:
The ratio of the amount of flour to the amount of buttermilk=99:1
Step-by-step explanation:
Step 1: Determine quantity for each recipe
Quantity of flour=66 cups
Quantity of buttermilk=2/3 cups
Step 2: Calculate the total quantity of recipe
The expression for the total quantity is;
T=f+b
where;
T=total quantity of recipe
f=quantity of flour
b=quantity of buttermilk
In our case;
T=unknown
f=66 cups
b=2/3 cups
replacing;
T=(66)+(2/3)=66 2/3 cups
Step 3: Determine fraction of each
fraction of buttermilk=(2/3)/(66 2/3)=1/100
fraction of flour=66/(66 2/3)=99/100
Step 4: Determine ratio of flour to buttermilk
Amount of flour:amount of buttermilk
(99/100):(1/100)
The ratio of the amount of flour to the amount of buttermilk=99:1
A=-2 for both sides. So when applied, you’ll get -23=-23
