Answer:

Step-by-step explanation:

You can see from the table that 2 bracelets are made every 30 minutes.

There are 9 intervals of 30 minutes each in 4.5 hours.

So, the number of bracelets that are made in 4.5 hours is

9x2=18

Another way to see this is to note from the table that 4 bracelets are made in 60 minute, which is 1 hour. So, in 4 hours, 16 bracelets will be made. Also, from the table, 2 bracelets are made in 30 minutes, which is 1/2 hour. So, adding up, 18 bracelets are made in 4.5 hours.

Evaluate tangent ^-1 1

Vitek1552 [10]

ANSWER

${ \tan }^{ - 1} (1) = 45 \degree$

${ \tan }^{ - 1} (1) = \frac{\pi}{4}$

EXPLANATION

We want to evaluate:

${ \tan }^{ - 1} (1)$

We can use scientific calculator to evaluate this directly to obtain:

${ \tan }^{ - 1} (1) =45\degree$

${ \tan }^{ - 1} (1) = \frac{\pi}{4}$

You could have also let:

$x = { \tan }^{ - 1} (1)$

Then,

$\tan(x) = 1$

The angle whose tangents is 1 is

$x =45\degree$

$x = \frac{\pi}{4}$

Solve the system of equations - 8x + 3y = -17 and 3x - y = 7 by combining the<br> equlations.

NeTakaya

Given :

Two equations :

-8x + 3y = -17 ....1)

3x - y = 7 ....2)

To Find :

The solution of the system.

Solution :

Multiplying equation 2) by 3 and adding with equation 1), we get :

(-8x + 3y) + 3(3x - y) = -17 + 21

x = 4

Putting above value of x equation 2) we get :

12 - y = 7

y = 5

Therefore, solution of system is ( 4,5 ).
