Answer:

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{FG}{MN}$ = $\frac{4}{2}$ = $\frac{2}{1}$

Thus the ratio of Δ EFG to Δ LMN = 2 : 1 → C

Vector u has initial point at (3, 9) and terminal point at (–7, 5). Vector v has initial point at (1, –4) and terminal point at

spin [16.1K]

Answer:

⟨-5, -1⟩

Step-by-step explanation:

Vector:

A vector is given by its endpoint subtracted by its initial point.

Vector u has initial point at (3, 9) and terminal point at (–7, 5)

Then

$u = (-7, 5) - (3,9) = (-7 - 3, 5 - 9) = (-10,-4)$

Vector v has initial point at (1, –4) and terminal point at (6, –1).

Then

$v = (6,-1) - (1,-4) = (6-1,-1-(-4)) = (5,3)$

What is u + v in component form?

$u + v = (-10,-4) + (5,3) = (-10+5,-4+3) = (-5,-1)$

⟨-5, -1⟩ is the answer.

Find the 12th term of the geometric sequence 1, –4, 16,

Digiron [165]

⇒ common ratio =r=3 and the given sequence is geometric sequence. Where an is the nth term, a is the first term and n is the number of terms. ⇒ 12th term is 708588 .

(May be wrong for some other users, although it's correct for me.)

Square root of 6 minus square root of 7 divided by square root of 6 plus square root of 7

zheka24 [161]

$\frac{ \sqrt{6}- \sqrt{7} }{ \sqrt{6}+ \sqrt{7} } \\ 
 Multiply \ and \ divide \ by \ the \ conjugate. \\ 
 =\frac{ \sqrt{6}- \sqrt{7} }{ \sqrt{6}+ \sqrt{7} } \times \ \frac{ \sqrt{6}- \sqrt{7} }{ \sqrt{6}- \sqrt{7} } \\ 
=$
$\frac{( \sqrt{6}- \sqrt{7})^2 }{ \sqrt{6}^2 - \sqrt{7}^2 }} \\ 
 =\frac{( \sqrt{6}- \sqrt{7})^2 }{-1} \\ 
 =-( \sqrt{6}- \sqrt{7})^2 \\ 
 = -( \sqrt{6}^2-2( \sqrt{6} \sqrt{7}+ \sqrt{7}^2 \\ 
 =-(6 -2 \sqrt{42} +7) \\ 
 =-6+2 \sqrt{42}-7 \\ 
 =-13+2 \sqrt{42} \\ 
Answer: \ -13+2 \sqrt{42}$
