Answer:

-10sin45+15cos60=Hor distance = 5.92 km

-10cos45+15sin60=ver distance = .429 km

resultant is sqrt(5.922+.4292)= 5.94 km at angle arctan(.429/5.92)= 1.77 degrees north of east

ale4655 [162]

Answer:

B

Step-by-step explanation:

To evaluate g(7) substitute x = 7 into g(x) , that is

g(7) = $\frac{7}{8}$ × 7 - $\frac{1}{2}$

= $\frac{49}{8}$ - $\frac{4}{8}$

= $\frac{45}{8}$ → B

The equationoflinevis y + 10 = 2 3 ( x – 8 ) . line w , which is parallel to line v , includes the point (6, -5) . what is the e

lbvjy [14]

You know that if 2 lines are parallel, they have the same slope.

First, find the slope of the given line;

y+10 = 23(x-8)
y=23x-184-10
y=23x-194

Slope is 23

Write out the basic format;

y=mx+c
y=23x+c <--- replace x and y values here
-5=23(6)+c
-5-138=c
-143=c

Therefore, this equation would be y=23x-143

Hope I helped :)
