Answer:

the ratio of the adjacent side to the hypotenuse is a function of the angle c, so we can write the symbol as cos(c) = value. 90

Step-by-step explanation: You can also see that 40 + 41 + 9 = 90. hope this helps

Which is the simplified form of (9c^-9)^-3<br> b 1/729 c^27

rosijanka [135]

<u>ANSWER</u>

$(9 {c}^{ - 9} )^{ - 3}=\frac{{c}^{ 27} }{729}$

<u>EXPLANATION</u>

The given expression is

$(9 {c}^{ - 9} )^{ - 3}$

Recall that:

$({a}^{m} )^{n} = {a}^{mn}$

We use the law of exponents to get

$(9 {c}^{ - 9} )^{ - 3} = 9^{ - 3} {c}^{ - 9 \times - 3}$

Let us multiply in the exponents to get:

$(9 {c}^{ - 9} )^{ - 3} = 9^{ - 3} {c}^{ 27}$

Recall again that:

${a}^{ - m} = \frac{1}{ {a}^{m} }$

This implies that:

$(9 {c}^{ - 9} )^{ - 3} = \frac{1}{ {9}^{ 3} } \times {c}^{ 27}$

We expand the power to get:

$(9 {c}^{ - 9} )^{ - 3} = \frac{1}{9 \times 9 \times 9} \times {c}^{ 27}$

$(9 {c}^{ - 9} )^{ - 3}=\frac{1}{729} \times {c}^{ 27}$

We multiply out to get:

$(9 {c}^{ - 9} )^{ - 3}=\frac{{c}^{ 27} }{729}$

What is the factorization of 121b4 − 49? (11b − 7)(11b − 7) (11b 7)(11b − 7) (11b2 − 7)(11b2 − 7) (11b2 7)(11b2 − 7)

Inessa05 [86]

The Factorization of 121b⁴ − 49 is (11b^2 + 7)(11b^2 - 7).

The equation 121b⁴ − 49

To find the Factorization of 121b⁴ − 49.

<h3>What is the factor of a^2-b^2?</h3>

The factor of a^2-b^2 is (a+b)(a-b)

We have write the given equation in the form of a^2-b^2

$= 121b^4 - 49\\= (11b^2)^2 - 7^2\\= (11b^2 + 7)(11b^2 - 7)$

Therefore the factor of the 121b^4 − 49 is (11b^2 + 7)(11b^2 - 7).

Can Someone Help Please.

Answer:

1. y = 9280 - 20x

2. f(y) = 6.37y - 3

Step-by-step explanation:

1. The equation is given to be $\frac{1}{16}x + \frac{1}{320}y - 29 = 0$

Now, rearranging the function we can write

$\frac{y}{320} = 29 - \frac{x}{16}$

⇒ y = 9280 - 20x

Hence, this is the equation as a function of x. (Answer)

2. The given function is y - 6.37x = - 3

Therefore, we can write, y = 6.37x - 3

Hence, f(x) = 6.37x - 3

⇒ f(y) = 6.37y - 3.

Hence, option D is true. (Answer)
