Answer:

Option B is correct

Step-by-step explanation:

To subtract matrix A from matrix B which has the same size as matrix A, you find the pair corresponding elements (which share the same position in matrix) and perform the subtraction.

As shown in picture:

C = A - B

= [3-(-1) 2-0; -4-(-5) 6-2; 7-4 5-9]

= [4 2; 1 4; 3 -4]

=> Option B is correct

Help please I am very confused

The sides of the triangle occur in a ratio of 4 : 7 : 2, so if <em>x</em> is some positive number, then we can write each side's length in terms of <em>x</em> as 4<em>x</em>, 7<em>x</em>, and 2<em>x</em>.

The perimeter is 299 yd, so

4<em>x</em> + 7<em>x</em> + 2<em>x</em> = 299 yd

13<em>x</em> = 299 yd

<em>x</em> = (299 yd) / 13

<em>x</em> = 23 yd

Then the sides of the triangle have lengths of

4<em>x</em> = 4 • 23 yd = 104 yd

7<em>x</em> = 7 • 23 yd = 161 yd

2<em>x</em> = 2 • 23 yd = 46 yd

"Median" here refers to the side length between the shortest and longest sides, so the answer would be 104 yd.

What is the modulus and argument after (StartRoot 3 EndRoot) (cosine (StartFraction pi Over 18 EndFraction) + I sine (StartFract

fgiga [73]

Answer:

$|z| = 27$ -- Modulus

$\theta = \frac{\pi}{3}$ --- Argument

Step-by-step explanation:

Given

$((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6$

Required

Determine the modulus and the argument

We have that:

$z = ((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6$

Expand:

$z = (\sqrt 3)^6(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6$

$z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6$

A complex equation can be expressed as:

$z = |z| e^{i\theta}$

Where

$|z| = modulus$

$\theta = argument$

Where

$e^{i\theta} = (cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})$

So:

$z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6$ becomes

$z = 27(e^{i\frac{\pi}{18}})^6$

By comparison:

$e^{i\theta} = (e^{i\frac{\pi}{18}})^6$

This gives:

${i\theta} = i\frac{\pi}{18}}*6$

${i\theta} = i\frac{6\pi}{18}}$

${i\theta} = i\frac{\pi}{3}}$

Divide through by i

$\theta = \frac{\pi}{3}$

Hence, the modulus, z is:

$|z| = 27$

And the argument $\theta$ is

$\theta = \frac{\pi}{3}$

Express the ratio in lowest form:<br>1.5 kg: 350 g

irakobra [83]

Given:

The ratio is:

1.5 kg : 350 g

To find:

The lowest or simplest form of the given ratio.

Solution:

We know that,

1 kg = 1000 g

We have,

1.5 kg : 350 g

It can be written as

$1.5\ kg : 350\ g=\dfrac{1.5\ kg}{350\ g}$

$1.5\ kg : 350\ g=\dfrac{1.5\times 1000\ g}{350\ g}$

$1.5\ kg : 350\ g=\dfrac{1500\ g}{350\ g}$

$1.5\ kg : 350\ g=\dfrac{150}{35}$

$1.5\ kg : 350\ g=\dfrac{30}{7}$

Therefore, the lowest form of the given ratio is 30:7.
