Given the coordinates A (5, 7, -2) and B (8, 3, 4) in 3d space, express AB as:
lys-0071 [83]
The vector AB is found by subtracting the coordinates of point B from the coordinates of point A => (8, 3, 4) - (5, 7, - 2)

(8, 3, 4) - (5, 7, - 2) = (3, - 4, 6)

=>

a) a 3 x 1 column =

|  3  |
| -4  |
|  6  |

b) xi + yj + zk

=> 3i - 4j + 6k

Please help with this precalc!!! i desperately need help
Paladinen [302]

Step-by-step explanation:

4 is the A or Ampltiude

To find the period set it equal to 2 pi/B

\frac{2\pi}{b}  =  \frac{6}{1}

\frac{b}{2\pi}  =  \frac{1}{6}

b=

\frac{2\pi}{6}

b=

\frac{\pi}{3}

There is no phase shift

The midline or d or vertical shift is 1.

Our equation for 8 is

4 \sin( \frac{\pi}{6} x)  + 1

9.Use sin function. The a value is 2 or -2 your choice.

Set up the period equal to the equation

\frac{2\pi}{b}  =  \frac{\pi}{3}

\frac{b}{2\pi}  =  \frac{3}{\pi}

b =  \frac{3}{\pi}  \times 2\pi

Which equal 6.

B=6

There is no C and the D and Vertical Shift is 1.

Our equation is

2 \sin(6x)  + 1

WILL GIVE BRAINLIEST!<br> Given that ℓ1 ∥ ℓ2 and y = 20°, find x.<br> x = <br> °
BabaBlast [244]
X will equal 40.

EXPLANATION: since they’re parallel and these are opposite angles, add them together to equal 180.
x+(20)+3x=180.
add common variables.
4x+20=180
subtract 29 from both sides
4x=160
divide each side by 4 so isolate x
x=40
