Write the limit as a definite integral on the interval [a, b], where ci is any point in the ith subinterval. Limit Interval lim

geniusboy [140]

Answer:

The corresponding definite integral may be written as

$\int_a^b \mathrm{(4x + 11)}\,\mathrm{d}x$

The answer of the above definite integral is

$\int_a^b \mathrm{(4x + 11)}\,\mathrm{d}x = 98$

Step-by-step explanation:

The given limit interval is

$\lim_{||\Delta|| \to 0} \sum\limits_{i=1}^n (4c_i + 11) \Delta x_i$

$[a, b] = [-8, 6]$

The corresponding definite integral may be written as

$\int_a^b \mathrm{(4x + 11)}\,\mathrm{d}x$

$\int_{-8}^6 \mathrm{(4x + 11)}\,\mathrm{d}x$

Bonus:

The definite integral may be solved as

$\int_{-8}^6 \mathrm{(4x + 11)}\,\mathrm{d}x \\\\\frac{4x^2}{2} + 11x \left \|{b=6} \atop {a=-8}} \right. \\\\2x^2 + 11x \left \|{b=6} \atop {a=-8}} \right. \\\\ 2(6^2 -(-8)^2 ) + 11(6 - (-8) \\\\2(36 - 64 ) + 11(6 + 8) \\\\2(-28 ) + 11(14) \\\\-56 +154 \\\\98$

Therefore, the answer to the integral is

$\int_a^b \mathrm{(4x + 11)}\,\mathrm{d}x = 98$

PLEASE PLEASE HELP WILL GIVE GIVE BRAINLIEST PLS!!!!!!!!!! Create a factorable polynomial with a GCF of 3x. Rewrite that polynom

Naily [24]

Answer:

Step-by-step explanation:

you can think in a reverse way:

Take

$3x(x^2+2x+3y^2)= 3x^3+6x^2+9xy^2.$

So the answer is

$3x^3+6x^2+9xy^2 = 3x(x^2+2x+3y^2)$

Geometry help with number 18!

lora16 [44]

BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36

Which of the following is the value of m? A. 18.5 B. 14.5 C. 29

Elanso [62]

The answer is 14.5 because :

2 times 2?5 = 5 so the denominator must have the same done, so 7.5 x 2.5 is 17.5. Subtract 3 from 7.5 and you get 14 .5 . So, m+ 14.5
