Hi!

[tex]\frac{1}{21-20} \left[\begin{array}{ccc}-3&10&\\2&-7&\end{array}\right][/tex]

(Determinant is 1 in this case)

Hence the inverse is:

[tex]\left[\begin{array}{ccc}-3&10\\2&-7&\\\end{array}\right][/tex]

The greeting is usually started with, "Dear (Person or agency name)"

the body is simply the place where you write what you want to write to the person.

Answer:

3 feet

Step-by-step explanation:

[tex]\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height}[/tex]

Given that the area is 6 ft² and the height is 4 ft,

6= ½ ×base ×4

Simplify:

2(base)= 6

Length of base

= 6 ÷2 (÷2 on both sides)

= 3 ft

Answer:

d = 16.7 in

Step-by-step explanation:

Since C = πd, d = C/π.          52.438 in

Here, with C = 52.438, d = ----------------- = 16.7 in

                                                  3.14

[tex]{\boxed{\boxed { \tt {d=16.7 in}}}}[/tex]

Since C=πd = c/π 52.438 in

C=52.438 , d = ________= 16.7 in

3.14

Answer:

Waves superimpose upon each other when they collide, while objects do not

Step-by-step explanation:

The main difference between the collision of waves and the collision of objects is simply the superposition principle.

When waves collide, they do not do so in the same way objects do. The superposition principle explains that waves can either collide in a constructive or destructive manner.

Case A: Waves colliding in a constructive manner

When waves collide in a constructive manner, this means that they are in phase, in simpler terms, it means that they have the same shape as they move through space-time. Constructive collision leads to a formation of a bigger wave with a higher amplitude. This is how stereo speakers operate. They produce louder sounds by releasing the same audio waves, causing them to superimpose upon each other.

Case B: Waves colliding in a destructive manner:

When waves are out of phase(i.e do not have the same shape as they move through space-time) and they collide, they try to cancel each other out, leading to a new wave with a weaker amplitude. This is how noise-cancelling headphones work. They emit an equal and opposite wave sound to the noise around your ears, thus cancelling it out.

Answer:

D

Step-by-step explanation:

Answer:

52.4 cm

Step-by-step explanation:

Circumference of a circle = 2πr

Radius, r = diameter / 2

= 17 cm / 2

= 8.5 cm

π = 3.14

Circumference of a circle = 2πr

= 2 × 3.14 × 8.5

= 53.38 cm

Approximately 52.4 cm

positive sign

I hope it's helps you ❤️☺️

Answer:

The answer is B.

Step-by-step explanation:

Hope this helps! Have an Amazing day!!

Answer:

❤️❤️ your answer is either 1 or 9 and i show the work for when you get the answer 1 and the work for haw you get the answer 9 if there is something wrong with my problem just let me know thanks ❤️❤️

Step-by-step explanation:

3x+4(8)=5x+2(7)

3x+32=5x+14

    -14       -14

3x+18=5x

-3x      -3x

18=2x

x=9

__________________________________________________________

3x+4=5x+2

    -2      -2

3x+2=5x

-3x    -3x

2=2x

x=1

The missing step

The missing step is at step 2.

At step 1, we have:

[tex]\frac{1}{2} - 2x +1 = -\frac{13}{2}[/tex]

At step 2, we have:

[tex]\frac{3}{2} - 2x= -\frac{13}{2}[/tex]

What she did at step 2, is that:

She collected like terms; 1 and [tex]\frac{1}{2}[/tex]

Then she simplified the like terms: [tex]1 + \frac{1}{2} =\frac{3}{2}[/tex]

Hence (a) is correct

Answer:

7

Step-by-step explanation:

Firstly, let us divide the two numbers as so-

[tex]645/87=7.41379310345\\[/tex]

To round a number to the nearest integer, look at the decimal places.

Here we have .41 - The 4 is less than 5, so it cannot round the ones place to 8.

So our answer here is 7.

Answer:

y=−x+3

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b

is the y-intercept.

y=mx+b
