You could first convert them to decimals to make it easier for you then reconvert it to fraction. 5.5 + 4.2=9.7 which is 9 and 7/10.

5 5/10 = 5.5
4 2/10 = 4.2
Add 9.7

Given f(x) = −9x5 − x4 + 3x3 − 8 and g(x) = −9x5 − 3x3 − 9x2 + 7, find and simplify f(x) − g(x)

KatRina [158]

F(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 − (<span>−9x^5 − 3x^3 − 9x^2 + 7)
</span>f(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 + 9x^5 + 3x^3 + 9x^2 − 7
f(x) − g(x) = − x^4 + 6x^3 +  9x^2 - 15

Precalculus Homework help please.

Answer:

see explanation

Step-by-step explanation:

(5)

Using the trigonometric identity

sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x

Given

3sin²Θ + 2cos²Θ - 2

= 3sin²Θ + 2(1 - sin²Θ) - 2

= 3sin²Θ + 2 - 2sin²Θ - 2

= sin²Θ

(6)

Using the trigonometric identity

secx = $\frac{1}{cosx}$

Consider the left side

$\frac{cosx}{1-sin^2x}$

= $\frac{cosx}{cos^2x}$

= $\frac{1}{cosx}$ = secx = right side ⇒ verified

(7)

Using the trigonometric identity

1 + cot²x = csc²x

Given

sin²x. cot²x + sin²x ← factor out sin²x from each term

= sin²x(cot²x + 1)

= sin²x. csc²x

= sin²x × $\frac{1}{sin^2x}$ = 1
