Answer:

Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary usually a fruit while gymnosperms have no flowers or fruits, and have unenclosed or seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones.

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

Use the figure shown. Let point D be at (-4,1) . Use the sides of triangle BDA to find the slope of the line.
gavmur [86]

The slope of the line shown in the figure having equation x + 2y = 0 is 1/2.

The point A is at ( -2 , 1 ), point B is at ( -4 , 2 ) and Point C is at ( -2 , 2 ).

Let point D be at ( -4 , 1 ).

Now the new triangle is ΔBDA and the corner points are A is at ( -2 , 1 ), point B is at ( -4 , 2 ) and  point D is at ( -4 , 1 ).

The equation of line passing through two points  is given by:

(y-y_{1} ) = (\frac{y_{2}-y_{1}  }{x_{2} - x_{1} })(x - x_{1} )

The equation of line passing through two points A( -2 , 1 ) and B( -4 , 2 ) IS

y - 1 = ((2-1)/(-4-(-2)))  (x-(-2))

y - 1 = (1/(-2)) (x+2)

2y -2 = -x -2

x + 2y = 0

The equation of straight line is x + 2y = 0

The equation in slope intercept form can be written as,

y = x/2 + 0

Slope = m = 1/2

Intercept = c = 0

So, we can conclude that 1/2 is the slope of the line .

Logan opened a savings account 21 years ago with a deposit of $3,471.52. The account has an interest rate of 3.1% compounded mon
notka56 [123]
P = $3,471.52, the principal
r = 3.1% = 0.031, annual ratr
n = 12, monthly compounding
t = 21 years

Note that n*t = 252.

The value after 21 years is
A = 3471.52*(1 + 0.031/12)²⁵²
   = $6,650.91

The interest earned is
6650.91 - 3471.52 = 3179.39

Answer: $3,179.39
