An employee makes a gross salary of 48,000 per year 15% of that money goes toward taxes of the employee invest 20% of his gross

kolezko [41]

First calculate his gross salary after his 401k contributions:
$x = 48000 - (48000 \times 0.20) \\ x = 38400$

Then find the amount of taxes withheld:
$t = 38400(0.15) \\ t = 5760$

5,760 dollars went towards taxes.

Expanding and Simplifying Triple Brackets:<br> (4x + 6) (x - 3)<br> Please help!<br> Thankyou all! X

Otrada [13]

This would only be a double bracket...

but you do
(4x+6) (x-3)
F 4x * X = 4xsquared
O 4x* -3 = -12x
I. 6xX = 6x
L. 6*-3 = -18
collect like terms:
answer= 4x2 - 6x -18
the 4x is squared :)

5) Establish the indentity (cot + tan ) sin = sec . Show each step to justify your conclusion.

katen-ka-za [31]

Answer:

Step-by-step explanation:

Identities : -

cot = cos / sin

tan = sin / cos

( cot + tan ) sin = sec

LHS

= ( cot + tan ) sin

= ( ( cos / sin ) + ( sin / cos ) ) sin

= ( ( cos sin ) / sin ) + ( sin² / cos )

= cos + ( sin² / cos )

LCM = cos

= ( cos² / cos ) + ( sin² / cos )

= ( cos² + sin² ) / cos

Identity : -

cos² + sin² = 1

= 1 / cos

= sec

= RHS

Hence proved.
