Answer:

Angle A=116\°

Step-by-step explanation:

Given:

Three angles of a triangle ABC.

A(9x+17)\\B(3x-4)\\C(6x-31)

Angle sum of a triangle is always = 180°

∴ A+B+C=180\°

Plugging in values of A,B \ and\ C

(9x+17)+(3x-4)+(6x-31)=180

Combining like terms.

9x+3x+6x+17-4-31=180

18x-18=180

Adding 18 both sides.

18x-18+18=180+18

18x=198

Dividing both sides by 18.

\frac{18x}{18}=\frac{198}{18}

∴ x=11

Angle A=9x+17

Plugging in value of x

Angle A=9(11)+17

Angle A=99+17

Angle A=116\°

The graph of f(x) = 6(0.25)x and its reflection across the y-axis, g(x), are shown.
jeka57 [31]

<u>Answer-</u>

The domain of g(x) is all real numbers.

<u>Solution-</u>

The given function is,

f(x)=6(0.25)^x

The reflection across y-axis of a point (x, y) will be (-x, y)

So, the reflection of the given function across y-axis will be,

g(x)=6(0.25)^{-x}

It is an exponential function. The domain of exponential functions is all real numbers and the range is all real numbers greater than zero.

Therefore, first option is correct.

Zoe's Fish tank holds 27 L of water she uses a 3L container to fill the tank how many times does she have to fill the three litt
Marianna [84]
<h2>Answer:</h2>

Zoe's Fish tank holds 27 L of water, so this is the capacity of the tank. On the other hand, Zoe uses a 3L container in order to fill the tank, so the question is  how many times does she have to fill the three litter container in order to fill the fish tank? Let's solve this as follows:

First time:

She pours 3L

Second time:

She pours another 3L, but she previously poured 3L, so she has poured 6L

Third time:

She pours another 3L, but she previously poured 6L, so she has poured 9L

Fourth time:

She pours another 3L, but she previously poured 9L, so she has poured 12L

Fifth time:

She pours another 3L, but she previously poured 12L, so she has poured 15L

Sixth time:

She pours another 3L, but she previously poured 15L, so she has poured 18L

Seventh time:

She pours another 3L, but she previously poured 18L, so she has poured 21L

Eighth time:

She pours another 3L, but she previously poured 21L, so she has poured 24L

Ninth time:

She pours another 3L, but she previously poured 24L, so she has poured 27L

<em>According to this, she needs to pours the </em><em>3L </em><em>container nine times in order to fill the fish tank. This can also be solved dividing </em><em>27L/3L= 9</em>
