Consider the integral 8 (x2+1) dx 0 (a) Estimate the area under the curve using a left-hand sum with n = 4. Is this sum an overe
Elina [12.6K]

Answer:

  (a) 120 square units, underestimate

  (b) 248 square units, overestimate

Step-by-step explanation:

(a) <u>left sum</u>

The left sum is the sum of the areas of the rectangles whose width is the total interval width (8-0) divided by the number of divisions (n=4). The height of each rectangle is the function value at its left edge.

We can compute the sum by adding the function values and multiplying that total by the width of the rectangles:

  left sum = (1 + 5 + 17 + 37)×2 = 60×2 = 120 . . . square units

The curve is increasing throughout the interval of interest, so the left sum underestimates the area under the curve.

__

(b) <u>right sum</u>

The rectangles whose area is the right sum are shown in the attachment, along with the table of function values. The right sum is computed the same way as the left sum, but using the function value on the right side of each subinterval.

  right sum = (5 + 17 + 37 + 65)×2 = 124×2 = 248 . . . square units

The curve is increasing throughout the interval of interest, so the right sum overestimates the area under the curve.

_____

The actual area under the curve on the interval [0, 8] is 178 2/3, just slightly less than the average of the left- and right- sums.

*If diagonal of a square is of length 10√2 cm then the perimeter of square is ...............cm.*
Artyom0805 [142]

Answer: 1️⃣ 40

Step-by-step explanation:

<em>x - is the side of the square</em>

<em />x^{2} +x^{2}   =(10\sqrt{2})^{2}  \\2x^{2}}  =200\\2x^{2} \div  2=200 \div  2 \\x^{2} =100\\x=\sqrt{100} \\x=10 \:  [cm] - side \: of  \: a \: square<em />

<em>Find the perimeter of the square.</em>

<em>Perimeter of the square = 4 × 10 cm = 40 cm</em>

Adrian purchases 6 tubes of paint and 3 paintbrushes at a craft store. Each tube of paint costs $2.50 and each paintbrush costs
Airida [17]

Answer:

$14.50

Step-by-step explanation:

6 x $2.50 = $15.00

3 x $0.50 = $1.50

$15.00 + $1.50 = $16.50

$16.50 - $2.00 = $14.50

Someone please help!!
pantera1 [17]

The answer I got was 2,423,000 million square miles. If there is a choice that says that then it’s the answer. If not, I’m probably wrong.

Hope this helps!
