Find the midpoint M of the line segment joining the points A = (-7, -6) and B = (3, 4).

Colt1911 [192]

Answer:

The midpoint is (-2,-1)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

( -7+3)/2 = -4/2 =-2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(-6+4)/2 = -2/2 =-1

The midpoint is (-2,-1)

Answer:

Recursive formula for geometric sequence

$a_{n}=a_{n-1}\times r$

is $a_{n}=a_{n-1}\times 6$

and explicit formula for geometric sequence $a_{n}=a_{1}^{r-1}$ is

$a_{n}=(\frac{1}{2})^{6-1}$

Step-by-step explanation:

Given sequence is $\frac{1}{2},3,18,108,648,...$

To find the recursive and explicit formula for this sequence:

Let $a_{1}=\frac{1}{2},a_{2}=3,a_{3}=18,a_{4}=108,a_{5}=648,...$

To find the common ratio r:

$r=\frac{a_{2}}{a_{1}}$

$=\frac{3}{\frac{1}{2}}$

$=3\times 2$

$=6$

Therefore r=6

$r=\frac{a_{3}}{a_{2}}$

$=\frac{18}{3}$

$=6$

Therefore r=6

Therefore the common ration r=6

Therefore the given sequence is geometric sequence

Recursive formula for geometric sequence is $a_{n}=a_{n-1}\times r$

$a_{n}=a_{n-1}\times 6$

and explicit formula is $a_{n}=a_{1}^{r-1}$

$a_{n}=(\frac{1}{2})^{6-1}$

$=(\frac{1}{2})^{5}$

$=\frac{1}{32}$

Therefore $a_{n}=\frac{1}{32}$

WITCHER [35]

f(x) = ax2+bx+c, is quadratic equation
function opening downward if the a<0,
kf(x) = -x², a= -1<0
so the answer is B.kf(x)
