-16 + (-22) - 14

First, simplify your brackets. / Your problem should look like: -16 - 22 - 14
Second, subtract -16 - 22 - 14 to get -52. / Your problem should look like: -52

Vector u = <11, 12>, v = <-16, 6>, and w = <4, -5>. Match each vector operation with its resultant vector expr
MAVERICK [17]

3u - 2v + w gives the resultant vector as; <49, 19>

8u - 6v gives the resultant vector as; <184, 60>

7v - 4w gives the resultant vector as; <61, 104>

u - 5w gives the resultant vector as; <-9, 37>

<h3>How to find the resultant of vectors?</h3>

We are given the vectors;

u = 11i + 12j

v = -16i + 6j

w = 4i - 5j

1) 3u - 2v + w gives the resultant vector as;

3(11i + 12j) - 2(-16i + 6j) + 4i - 5j

⇒ 33i + 36j + 32i - 12j + 4i - 5j

⇒ 49i + 19j

⇒ <49, 19>

2) 8u - 6v gives the resultant vector as;

8(11i + 12j) - 6(-16i + 6j)

⇒ 88i + 96j + 96i - 36j

⇒ 184i + 60j

3) 7v - 4w gives the resultant vector as;

7(11i + 12j) - 4(4i - 5j)

⇒ 77i + 84j - 16i + 20j

⇒ 61i + 104j

4) u - 5w gives the resultant vector as;

11i + 12j - 5(4i - 5j)

11i + 12j - 20i + 25j

-9i + 37j

At the park, there is a triangular sandbox with base = 12ft and height = 4ft. A drawing of the sandbox is shown above. Brie want
sammy [17]

Your question is not clear, but it looks as though you want to know how Brie can make a similar sandbox with base = 8ft.

Answer:

For Brie to make a similar sandbox, he must use a base = 8ft, and height = (8/3)ft

Step-by-step explanation:

It is possible for Brie to make a similar triangular sandbox with base = 12ft and height = 4ft.

All he must ensure is that the ratio of base to height of the original sandbox is the same ratio of base to height of the one he is trying to make.

The original sandbox is 12:4

Because he wants to use a base = 8ft, the sandbox he is trying to make is 8:x

Where x is the height of the sandbox he is trying to make.

Then for these sandboxes to be similar, the ratio 12:4 = 8:x

=> 12/4 = 8/x

12x = 8 × 4

12x = 32

x = 8/3

The height must be (8/3)ft
