Answer: Expression used to find the total ribbon she used = x+11.2
Explanation:
Let the length of blue ribbon to use to make a bow for a dress be x
And
The length of brown ribbon is used to make a bow for a dress = 11.2 inches
Expression need to find the total ribbon she used will be sum of blue and brown ribbon altogether
i.e. x+11.2 inches
So, the required expression will be x+11.2 inches
We know, 4/2 = 2
& 4/4 = 1
So, 4/2 > 4/4
In short, Your Final Answer would be Option C
Hope this helps!
Answer:
(a) 120 square units (underestimate)
(b) 248 square units
Step-by-step explanation:
<u>(a) left sum</u>
See the attachment for a diagram of the areas being summed (in orange). This is the sum of the first 4 table values for f(x), each multiplied by 2 (the width of the rectangle). Quite clearly, the curve is above the rectangle for the entire interval, so the rectangle area underestimates the area under the curve.
left sum = 2(1 + 5 + 17 + 37) = 2(60) = 120 . . . . square units
<u>(b) right sum</u>
The right sum is the sum of the last 4 table values for f(x), each multiplied by 2 (the width of the rectangle). This sum is ...
right sum = 2(5 +17 + 37 +65) = 2(124) = 248 . . . . square units

Given :


let's solve for f(x) × g(x) :



therefore, correct choice is : D
