Vector v1 is 6.6 units long and points along the negative x axis. vector v2 is 8.5 units long and points at + 55° to the positiv
natita [175]
(a) what are the x and y components of each vector?
 For vector v1:
 
v1 = 6.6 (cos (180) i + sine (180) j)
 v1 = 6.6 (-1i + 0j)
 v1 = -6.6i
 
For vector v2:
 
v2 = 8.5 (cos (55) i + sine (55) j)
 v2 = 8.5 ((0.573576436) i + (0.819152044) j)
 v2 = 4.88 i + 6.96 j
 (b) determine the sum v v 1 2

 The sum of both vectors is given by:
 v1 + v2 = (-6.6i) + (4.88 i + 6.96 j)
 Adding component to component:
 v1 + v2 = (-6.6 + 4.88) i + (6.96) j
 v1 + v2 = (-1.72) i + (6.96) j

Find the slope of the line through the points (6,16) and (−6,4)
MakcuM [25]

m = \frac{y2-y1}{x2-x1}

m = \frac{4-16}{-6-6} \\m = \frac{-12}{-12} \\\\m = 1

Therefore, the slope of the line is 1. In case if you want to know the equation.

y=mx+b\\y=x+b\\4=-6+b\\4+6=b\\10=b\\

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

y=mx+b\\y=x+b\\16=6+b\\16-6=b\\10=b\\

It's the same, you can use any orders given.

Overall, the slope is 1 and the equation is y=x+10

Find the volume of a pyramid with a square base, where the side length of the base is
Alexxandr [17]

Answer:

127.253 m^3

Step-by-step explanation:

To find the volume, we start by getting the area of the square base

Mathematically, that will be 4.9^2 m^2

To complete the volume, we multiply the area of the base by the height

= 4.9^2 * 5.3 = 127.253 m^3
