Answer:
f(-3)=56
Step-by-step explanation:
When evaluating a specific input for a function, you just plug that input in for x.
So in this case, f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(9)+6+5
f(-3)=45+6+5
f(-3)=56
1) 3/4 - 1/2 = 3/4 - 2/4 = 1/4. Vanessa's brothers ate half of the cake.
2) 1.75 + 2.4 = 4.15. 6.5 - 4.15 = 2.35. 4.15 = 2.35 = 1.8. Chad hiked 1.8 ore miles in the morning than in the afternoon.
This is a parabola that opens downward.
Remember that the axis of symmetry is located at x=-b/(2a).
So the vertex is at (3,-1)
So functions slope is positive or increasing on (-co, 3] and decreasing on [3,co).
30÷10=3
120÷3=40. As a result, there are 40 calories in 10 grams of the crackers. Hope it help!
Answer:
196ft^2
Step-by-step explanation:
direct the diagram as shown in my image attachment
A = 1/2 x (18-(9-7)) x (6+8) = 112ft^2
B = 2 x (6+8) = 28ft^2
C = 7 x 8 = 56ft^2
total area = 112 + 28 + 56 = 196ft^2
