Answer:

3. 6^9 / 6^-2

5. (6^3)^3

Step-by-step explanation:

What you do is solve for each of the expressions and each one that is less than 6^14 / 6^2 is your answer.

Let's start with what 6^14 / 6^2 equals:

6^14 / 6^2 = 2,176,782,336

Now lets start at the top and work our way down.

6^15 x 6^-2 = 470,184,984,576 This is bigger than 6^14 / 6^2 so this is not one of the answers.

6^8 / 6^-6 = 7.83641641 x10^10 This is bigger than 6^14 / 6^2 so this is not one of the answers.

6^9 / 6^-2 = 362,797,056 This is smaller than 6^14 / 6^2 so this is one of your answers.

6^16 x 6^-4 = 2,176,782,336 This is the same as 6^14 / 6^2 so this is not one of the answers.

(6^3)^3 = 10,077,696 This is smaller than 6^14 / 6^2 so this is one of your answers.

3. 6^9 / 6^-2

5. (6^3)^3

These are your answers.

Hey there! Your answer should be the first one and the second one. I do hope it was right. So sorry if I was wrong. Hope it helped! Your fellow Brainly user, GalaxyGamingKitty.

How do you this question (pre-cal)

Novay_Z [31]

The goal to proving identities is to transform one side into the other. We can only pick one side to transform while the other side stays the same the entire time. The general rule of thumb is to transform the more complicated side (though there may be exceptions to this guideline).

So I'll take the left hand side and try to turn it into $\csc^2( B )$

One way we can do that is through the following steps:

$\frac{\tan(B) + \cot(B)}{\tan(B)} = \csc^2(B)\\\\\frac{\tan(B)}{\tan(B)} + \frac{\cot(B)}{\tan(B)} = \csc^2(B)\\\\1 + \cot(B)*\frac{1}{\tan(B)} = \csc^2(B)\\\\1 + \cot(B)*\cot(B) = \csc^2(B)\\\\1 + \cot^2(B) = \csc^2(B)\\\\1 + \frac{cos^2(B)}{\sin^2(B)} = \csc^2(B)\\\\\frac{sin^2(B)}{\sin^2(B)}+\frac{cos^2(B)}{\sin^2(B)} = \csc^2(B)\\\\\frac{sin^2(B)+cos^2(B)}{\sin^2(B)} = \csc^2(B)\\\\\frac{1}{\sin^2(B)} = \csc^2(B)\\\\\csc^2(B)=\csc^2(B) \ \ {\Large \checkmark}\\\\$

Since we've shown that the left hand side transforms into the right hand side, this verifies the equation is an identity.

Mrs. Fronkos class for evry 6 boys there are 8 girls. Write the ratio of boys to girls in simplest form

Rama09 [41]

Answer:

3:4

Step-by-step explanation:

there are 6 boys for every 8 girls, so the initial ratio is 6:8. however, this can be simplified by finding a number both 6 and 8 are evenly divisible by. In this case, you can divide the ratio by 2. 6/2 = 3 and 8/2 = 4, which is why the simplified form is 3:4

ΔXYZ was reflected to form ΔLMN.

goldfiish [28.3K]

ΔXYZ was reflected to form ΔLMN, hence ΔXYZ ≅ ΔLMN, ∠X ≅ ∠L and XZ ≅ LN

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Reflection is a rigid transformation, hence it produces congruent figures with congruent angles.

∠Y + ∠X + ∠Z = 180 (angle in a triangle)

86 + 38 + ∠Z = 180

∠Z = 56°

Also:

∠N + ∠M + ∠L = 180 (angle in a triangle)

86 + 56 + ∠L = 180

∠L = 38°

ΔXYZ was reflected to form ΔLMN, hence ΔXYZ ≅ ΔLMN, ∠X ≅ ∠L and XZ ≅ LN
