Answer:

C = 2(3.14)r

C = (3.14)d

Step-by-step explanation:

Circumference in terms of radius:

c \:  = 2\pi \: r

So replacing pi with 3.14 you would get 2(3.14)r

Circumference in terms of diameter:

c = d\pi

So replacing pi with 3.14 you would get d(3.14)

If 40% of a number is 56. What was the original Number
pentagon [3]
56 divided by 40 is 1.4. Multiply that by 100 and you get 140.

This is the long way of doing it, but it's the way I've always done it.

Find the coefficient of x^4 in the expansion of (1 + 2x + 3x^3)^10?
Lesechka [4]
(1+2x+3x^3)^{10}

The only possible configurations of terms that contribute to generating the x^4 term in the expansion are given by the multinomial theorem to be

\left(\dbinom{10}{6,4,0}(1)^6(2x)^4(3x^3)^0+\dbinom{10}{8,1,1}(1)^8(2x)^1(3x^3)^1\right)x^4

where

\dbinom{10}{k_1,\ldots,k_m}=\dfrac{10!}{k_1!\cdots k_m!}

Simplifying a bit gives a coefficient of

\dbinom{10}{6,4,0}(2)^4+\dbinom{10}{8,1,1}(2)(3)
16\dbinom{10}{6,4,0}+6\dbinom{10}{8,1,1}
16\dfrac{10!}{6!4!0!}+6\dfrac{10!}{8!1!1!}
16(5\times3\times2\times7)+6(10\times9)=3900

Midpoints of segment with endpoints. (-4,2) and (2,4)
sashaice [31]

Well! See ,If the endpoints are (x1,y1) & (x2,y2) then mid-point is given by (x1+x2)/2,

(y1+y2)/2

Here in this question endpoints given for the line segment are (-4,2) , (2,4) so we have to find mid-point for x and y co-ordinates by applying above rule.

So, the mid-point we get is (-4+2)/2 , (2+4)/2.

i.e. (-1,3) which lies in 2nd Co-ordinate!

Hope it helps!!

poizon [28]
Midpoint formula: (x1+x2)/2, (y1+y2)/2
(1+5)/2 = 6/2 = 3 for x
(5+2)/2 = 7/2 = 3.5 for y
Midpoint: (3,3.5)
