The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?
natulia [17]

Answer:

( - 1,1,3 )

Step-by-step explanation:

Use the midpoint formula:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}, \frac{z_1+z_2}{2} )

We want to find the midpoint of the line

that has endpoints.

(\frac{ - 6+4}{2},\frac{3+ - 1}{2}, \frac{4+2}{2} )

We simplify to get;

(\frac{ - 2}{2},\frac{2}{2}, \frac{6}{2} )

This finally gives:

( - 1,1,3 )

The correct answer is A.

After the first term in a sequence, the ratio of each term to the preceding term is r. If the first term is a, what is the third
irinina [24]

Answer:

The 3rd term is

ar^2

Step-by-step explanation:

From the given information, the first term of the sequence is

a_1=a

The common ratio of the sequence is

r

The explicit formula for a geometric sequence is :

a_n=a_1(r^{n-1})

To find the third term, we put n=3 to get:

a_n=a(r^{3-1})

This simplifies to:

a_3=ar^2
