6(4(-4) - 6(2/3) -(-7(-4))

4 * -4 = -16

-6 * 2/3 = -4

-7 * -4 = 28

6(-16 - 4 - 28)

6(-48)

(8CQ) Find the sum of the geometric series. <br> 20-10+5-5/2+...

Ivahew [28]

Answer:

b. $\frac{40}{3}$

Step-by-step explanation:

The given geometric series is;

$20-10+5-\frac{5}{2}+...$

The first term of this series is

$a_1=20$

The common ratio is

$r=\frac{-10}{20}=-\frac{1}{2}$

The sum to infinity of this series is

$S_{\infty}=\frac{a_1}{1-r}$

Substitute the given values to obtain;

$S_{\infty}=\frac{20}{1--\frac{1}{2}}$

This implies that;

$S_{\infty}=\frac{20}{\frac{3}{2}}$

$S_{\infty}=\frac{40}{3}$

Solve for x.<br> y=a(x-h)^2+k

Natasha_Volkova [10]

Answer:

B ±sqrt((y-k)/a ) + h= x

Step-by-step explanation:

y=a(x-h)^2+k

Subtract k from each side

y-k = a(x-h)^2+k-k

y-k = a(x-h)^2

Divide by a

(y-k)/a = a(x-h)^2/a

(y-k)/a = (x-h)^2

Take the square root of each side

±sqrt((y-k)/a )= sqrt((x-h)^2)

±sqrt((y-k)/a )= (x-h)

Add h to each side

±sqrt((y-k)/a ) + h= (x-h+h)

±sqrt((y-k)/a ) + h= x

Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the

netineya [11]

Answer:

$P = (2,5)$

Step-by-step explanation:

Given

$A(-4,8)$

$B(6,3)$

$m:n = 3 : 2$

Required

Determine P

Since P divides the segment into 3:2, P is calculated using

$P = (\frac{nx_1 +m x_2}{m+n},\frac{ny_1 + my_2}{m+n})$

Where

$(x_1,y_1) = (-4,8)$

$(x_2,y_2) = (6,3)$

$m:n = 3 : 2$

Substitute these values in the above formula:

$P = (\frac{2 * -4 +3 * 6}{3 + 2},\frac{2 * 8 + 3 * 3}{3 + 2})$

$P = (\frac{-8 +18}{3 + 2},\frac{16 + 9}{3 + 2})$

$P = (\frac{10}{5},\frac{25}{5})$

$P = (2,5)$
