You add all them together and get 63 then divide by 9 and you get 7

Answer: B, 7

Step-by-step explanation: Mean is adding all numbers then dividing so 4 + 6 + 6 + 7 + 7 + 8 + 8 + 8 + 9 is 63 and then divide it by the total numbers (9)

63 divided by 9 is 7

7 is the mean, or B

Find the line integral with respect to arc length ∫C(8x+5y)ds, where C is the line segment in the xy-plane with endpoints P=(7,0

puteri [66]

a. Parameterize $C$ by

$\vec r(t)=(1-t)(7,0)+t(0,5)=(7-7t,5t)$

with $0\le t\le1$

b. The integral is to be computed over the range of the parameter $t$ .

c. The integral has a value of

$\displaystyle\int_C(8x+5y)\,\mathrm dS=\int_0^1(8x(t)+5y(t))\|\vec r(t)\|\,\mathrm dt$

$\displaystyle=\int_0^1(8(7-7t)+5(5t))\|(-7,5)\|\,\mathrm dt$

$\displaystyle=\sqrt{74}\int_0^1(56-31t)\,\mathrm dt=\boxed{81\sqrt{\dfrac{37}2}}$

Please guys help me with this

likoan [24]

oh this is easy! it just means 121 divided by 11, which is a whole number anyway. you just need to know your 11 times tables.

11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121,...

the answer is 11 because 11 goes into 121, 11 times.
