Answer:

The vector will change in direction and decrease in magnitude

Step-by-step explanation:

Given:

vector multiplication by -π/4

-π/4= -0.785

Due to the negative sign "-", the, vector will change/reverse its direction.

And as of the magnitude, 0.785<1 hence the magnitude of vector will be decreased by this factor !

<h2>Hello!</h2>

The answer is:

Answer: 34

Units: Joules

KE=34J

<h2>Why?</h2>

The kinetic energy is the work needed to accelerate an object to a determined speed.

The kinetic energy can be calculated using the following equation:

KE=\frac{1}{2}mv^{2}

Where,

m, is the mass of the object.

v, is the speed of the object.

So, we are given the information:

mass=17kg\\\\v=\frac{2m}{s}

Then, substituting and calculating we have:

KE=\frac{1}{2}mv^{2}

KE=\frac{1}{2}*17kg*(\frac{2m}{s})^{2}

KE=8.5kg*(\frac{4m^{2}}{s^{2}})

KE=34\frac{kg.m^{2}}{s^{2}}=34J

Have a nice day!

For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'

cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200

A composite figure has three congruent triangles removed from it.
Advocard [28]
16•16=256

A quarter is missing so 256/4=64

64•3=192 is the total square area.

When you find the area of a triangle you usually do (b•h)/2

Since this right here is equal triangles for both ways you can simply divide 192/2=96ft^2
