What is an equation of a line that passes through the point (10,5) and is perpendicular to the line whose equation is y=5/4x-2?

Maurinko [17]

y = mx + b

slope(m) = -4/5

(10,5)...x = 10 and y = 5

now sub into the formula and find b, the y int

5 = -4/5(10) + b

5 = -40/5 + b

5 = -8 + b

5 + 8 = b

13 = b

so ur perpendicular equation is : y = -4/5x + 13 <===

Hope this helps!

What is the common ratio of the sequence? -2,6,-18,54

aivan3 [116]

ANSWER

The common ratio is -3.

EXPLANATION

In general, the common ratio of a Geometric Sequence is given by:

$r = \frac{a_{n+1}}{a_{n}}$

We can find the common ratio using any two consecutive terms of the geometric sequence by dividing the subsequent term by the previous term.

The given sequence is -2,6,-18,54

Using the first two terms the common ratio is

$r = \frac{6}{ - 2} = - 3$

We could also used the second and third terms to get

$r = \frac{ - 18}{6} = - 3$

and so on and so forth.

Therefore the common ratio is -3.
