Answer:

We have the equation A*C = A

Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.

We can divide both sides by A and get:

(A*C)/A = A/A

C = 1

So here we finded the value of A.

If A and C are matrices, then C is the identity matrix.

Answer:

B) 10 cm

Step-by-step explanation:

Hello!

We can use the Pythagorean theorem to solve for the hypotenuse.

Formula: $a^2 + b^2 = c^2$

a = leg
b = leg
c = hypotenuse

We can plug in the values for each leg to solve for the hypotenuse.

<h3>Solve for c</h3>

$a^2 + b^2 = c^2$
$6^2 + 8^2 = c^2$
$36 + 64 = c^2$
$100 = c^2$
$\sqrt{100} = \sqrt{c^2}$
$10 = c$

The answer is Option B: 10 cm

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s an

NeX [460]

Answer:

$6400\ \text{N}$

Step-by-step explanation:

$\dfrac{m}{t}$ = Mass flow rate of water = 320 kg/s

$m$ = Mass of water on the door

$t$ = Time

$v$ = Velocity of water on the door = 20 m/s

Force is given by

$F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}$

The average force is exerted by the stream of water is $6400\ \text{N}$ .

Which is a factor of x2 + 5x − 24?

Ad libitum [116K]

Answer:

(x−3)(x+8)

Step-by-step explanation:

The middle number is 5 and the last number is -24.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 5

Multiply together to get -24

Can you think of the two numbers?

Try -3 and 8:

-3+8 = 5

-3*8 = -24

Fill in the blanks in

(x+_)(x+_)

with -3 and 8 to get...

(x-3)(x+8)
