5 0

Answer:

Step-by-step explanation:

It's a quartic trinomial because its has a fourth degree variable in the expression and only 3 variables in the equation.

2x⁴ - x + 5.

Linear trinomials have 1 degree 3 variables in the monomial. Eg x + y + 2 = 0 is an example of a linear trinomial.

Cubic trinomials have 3 degree and 3 variables in the equation eg = 5x³ + 2x + 1 = 0

Quadratic trinomials is the most common trinomial we deal with everyday eg Ax² + bx + c = 0

The sum of mike and Jordan’s age is 51. The difference in their ages is 17. If mike is older, what are the two men’s ages?

iogann1982 [59]

Answer:

Step-by-step explanation:

You can make equations.

M+J=51

M-J=17

Subtracting first equation from second equation:

2J=34

J=17 Jordan is 17

Therefore, Mike, is 34.

You have read 4 of the books shown. Which choice shows 2 ways of writing the fraction of these books that you read?

Olegator [25]

Total books read: 4

Total books in list: 12

So it can be shown as:

$\sf \dfrac{read \ books}{total \ books \ in \ list}$

$\hookrightarrow \sf \dfrac{4}{12}$

on simplifying

$\hookrightarrow \sf \dfrac{1}{3}$

So, option 1 is correct.

Answer:

See Explanation Below

Step-by-step explanation:

Given

$(sin x - cos x)^2 = sec^2x - tan^2x - 2sinx.cos x.$

Required

Prove

To start with; we open the bracket on the left hand side

$(sin x - cos x)^2 = (sin x - cos x)(sin x - cos x)$

$(sin x - cos x)^2 = (sin x )(sin x - cos x)- (cos x)(sin x - cos x)$

$(sin x - cos x)^2 = sin^2 x -sinx cos x - sin xcos x + cos^2 x$

$(sin x - cos x)^2 = sin^2 x -2sinx cos x + cos^2 x$

Reorder

$(sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x$

From trigonometry;

$sin^2x + cos^2x = 1$

So;

$(sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x$

becomes

$(sin x - cos x)^2 = 1 - 2sinx cos x$

Also from trigonometry;

$sec^2x - tan^2x = 1$

So,

$(sin x - cos x)^2 = 1 - 2sinx cos x$

becomes

$(sin x - cos x)^2 = sec^2x - tan^2x - 2sinx cos x$
