andrew-mc [135]

Answer:

Multiply vector c by the scalar -1/2.

Step-by-step explanation:

Look at vector c.

It has an x component of 4 and a y component of 4.

You can write vector c as a sum of its components using unit vectors in the x direction (i) and in the y direction (j).

c = 4i + 4j

Now look at vector d, and write it also as a sum of its x and y components.

d = -2i - 2j

Now ask yourself, what operation do I do to 4 to end up with -2?

One answer is to multiply 4 by -1/2.

d = (-1/2)c = (-1/2)(4i) + (-1/2)(4j) = -2i - 2j

That worked. By multiplying vector c by the scalar -1/2, you end up with vector d.

An artist wants to make alabaster pyramids using a block of alabaster with a volume of 576 cubic inches. She plans to make each

8_murik_8 [283]

Volume of pyramid:

$V= \dfrac{1}{3} \cdot A \cdot H$

A - base area
H - height

First count volume of one pyramid:

$V=\dfrac{1}{3} \cdot 3 \cdot 4=4 [\hbox{inch}^3]$

So by using 576 inch^3 you can make 576 : 4 = 144 pyramids

Derek is playing a prank on Grace and hid her pencil inside a tissue box that has a width of 4 inches, a length of 8 inches, and

ohaa [14]

Answer:

9.8 Inch

Step-by-step explanation:

The distance from the upper left corner to the bottom right corner of the box is the longest diagonal of the box.

For a rectangular prism:

Length of the Longest diagonal $=\sqrt{ l^2+h^2+w^2}$

Therefore:

Length of the pencil $=\sqrt{ 8^2+4^2+4^2}$

$=\sqrt{96}\\=9.8$ inch(correct to the nearest tenth of an inch)$
