4. Given directed line segment CD, if point E divides CD three-fourths of the way from C to D, find the coordinates of E, then p

cricket20 [7]

Answer:

Point E is given by $\left ( \frac{3mx_1+4x_0}{7},\frac{3y_1+4y_0}{7} \right )$

Step-by-step explanation:

Let points C and D be $(x_0,y_0),\,(x_1,y_1)$ and let point E divides it in ratio $m:n$ .

Then coordinates of point E are given by $\left ( \frac{mx_1+nx_0}{m+n},\frac{my_1+ny_0}{m+n} \right )$

Put $m:n=3:4$

Point E is given by $\left ( \frac{3mx_1+4x_0}{3+4},\frac{3y_1+4y_0}{3+4} \right )=\left ( \frac{3mx_1+4x_0}{7},\frac{3y_1+4y_0}{7} \right )$

Now plot point E.

Perform the following divisions. be sure all answers are reduced to lowest terms. 7/12 ÷ 3/4 =

Free_Kalibri [48]

7/12 / 3/4

You can write it as

7/12 * 4/3

=28/36 = 14/18 = 7/9

Please help! What’s the error in line 1 ?

sveticcg [70]

Answer:

When you add variables with exponents, you do not add the exponents together.

The error -> $y^2+2y^2=3y^4$

In this case, they have added the exponent $2+2=4$ .

However, you do not add it. Instead, the answer should be $3y^2$

Given the following sequence, find the 12th term: {2, -4, 8,...} -4096 4096 2048 -2048

Nata [24]

Answer:

- 4096

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence.

r = - 4 ÷ 2 = 8 ÷ - 4 = - 2

This indicates the sequence is geometric with n th term

$a_{n}$ = a $r^{n-1}$

where a is the first term and r the common ratio

Here a = 2 and r = - 2 , thus

$a_{12}$ = 2 × $(-2)^{11}$ = 2 × - 2048 = - 4096
