Answer:

-1/2

Step-by-step explanation:

slope = rise/run = y1-y2/x1-x2 = -3-(-2)/-3-(-5) = -3+2/-3+5 = -1/2

What is the equation of the line that passes through the point (-4,2) and has a slope of 1/4

zubka84 [21]

Step-by-step explanation:

Equation of line is y-y1 = m(x-x1), where m is the slope and (x1,y1) is the given point.

y-2 = 1/4*(x-(-4))

y-2 = 1/4 * (x+4)

4*(y-2) = x+4

Equation of the line is,

x-4y = -12

Get the general term for the sequence being your t3 = 11 and the t20 = 244.2

marusya05 [52]

Answer:

nth term = $t_{n} = 7.639(1.2)^{n - 1}$

Step-by-step explanation:

Let us assume that the given sequence is a G.P.

Now, if the first term of the G.P. is a and the common ratio is r, then

Third term = $t_{3} = ar^{2} = 11$ .......... (1) and

20th term = $t_{20} = ar^{19} = 244.2$ ........... (2)

Now, dividing equation (2) with equation (1) we get

$\frac{ar^{19} }{ar^{2} } = \frac{244.2}{11} = 22.2$

⇒ $r^{17} = 22.2$

⇒ r = 1.2.

Hence, from equation (1) we get

a(1.2)² = 11

⇒ a = 7.639 (Approx.)

Therefore, the general term of the sequence i.e. nth term = $t_{n} = 7.639(1.2)^{n - 1}$ (Answer)

Is 2 a solution of the inequality 4 + a ≤ 6? *

zaharov [31]

Answer:

The answer is "Yes, 6 = 6"

Step-by-step explanation:

If you substitute 2 for A, you would get 4 + 2 is less than or equal to 6, which is true because 6 = 6.

Answer:

B. $cos^{-1} \bigg(\frac{4}{5}\bigg)$

Step-by-step explanation:

$\because \cos \angle B = \bigg(\frac{4}{5}\bigg)\\\\\therefore \angle B =cos^{-1} \bigg(\frac{4}{5}\bigg)\\$
