Answer:

D.) y = - 7/3x - 4

Step-by-step explanation:

* Parallel lines have the same slope *

7x + 3y = -3

1. Subtract 7x to both sides of the equal sign

3y = -7x - 3

2. Divide both sides by 3

y = -7/3 -1

3. The slope equals -7/3

4. All you need to do is find the answers that have the same slope

Hope this helps :)

Find t12 for a geometric sequence where t1=2+2i and r=3

vfiekz [6]

Answer:

$T_{12} = 354294 + 354294i$

Step-by-step explanation:

Given

Geometric Sequence (GP)

$T_1 = 2 + 2i$

$r = 3$

Required

Determine T₁₂

The nth term of a GP is calculated as thus;

$T_n = ar^{n-1}$

In this case;

$n = 12$ ; $r = 3$ and $a = T_1 = 2 + 2i$

Substitute these values in the above formula

$T_{12} = (2 + 2i) * 3^{12-1}$

$T_{12} = (2 + 2i) * 3^{11}$

$T_{12} = (2 + 2i) * 177147$

Open the bracket

$T_{12} = 177147 * 2 + 177147 * 2i$

$T_{12} = 354294 + 354294i$

<em>Hence, the 12th term of the sequence is </em> $T_{12} = 354294 + 354294i$

The resultant of a 15 pound force and an 8-pound force acting on an object is 10 pounds.

natali 33 [55]

Answer:

112 degrees.

Step-by-step explanation:

as we know that the three set of forces will form a triangle, by using cosine rule, we can find the required angle.

follow the diagram in the attachment.

by cosine rule for $\alpha$ ,

2*10*8*cos $\alpha$ = $8^{2} +10^{2} -15^{2} = 64+100-225= 164-225=-61$

now, dividing both sides by 2*10*8,

cos $\alpha$ = -61/160

$\alpha$ = 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)

That is 6 * sqrt(2*8*3*6)

= 6 sqrt 16 * sqrt 18

= 6 *4 * sqrt 9 * sqrt2

= 6*4*3 sqrt2
