Answer:

So scale factor, I'm either thinking multiplication or division, so here goes:

Step-by-step explanation:

So either division or multiplication is my guess.

We all know 7x2=14, so 14 divided by 7 is 2.

Now let's start a little easy for multiplication; 10x7, easy, 70.

7x4, easy, 28. 70+28= 98 now. So basically 14x7 is 98.

I remember the phrase scale factor from 7th grade.

So try to put the answer that is multiplied (98).

And if that doesn't work, try the divided version (2), vice versa.

Please correct me if I'm wrong, I took time out of my lunch break to write this lol.

Bye!

Answer:

33. B

34. D

35. D

36. A

Step-by-step explanation:

All these questions require is a calculator :). For question 35, all you want to put in is arccos(0.8192) and make sure your calculator is in degree mode. For 36, all you want to put in is arctan(0.3839). For 34, all you want to put in is arcsin(0.6018). For 33, all you want to put in is arcsin(0.6561).

What is the value of g in 1/3s + 14 = 26
DerKrebs [107]

Answer:

s = 36

Step-by-step explanation:

So what you do is isolate the s.

1. Subtract 14 from both sides of equation. You should have:

1/3s = 12

2. To isolate the s, you multiply by 3 on both sides to get rid of the fraction on the left side. You should have:

s = 36

To verify, plug into original equation:

1/3*(36) + 14 = 26

1/3 * 36 = 36/3 = 12

12 +14 = 26

We can verify.

The domain of the functions are:

  • The domain of f(x) = √4x + 6 is [-3/2, ∞) or x >-3/2
  • The domain of g(x) = -4√-20x - 6 is (-∞, -3/10] or x < -3/10
  • The domain of f(x) = 15 + √5x - 16 is [16/5, ∞) or x >16/5
  • The domain of p(x) = √20x + 6 is (-3/10, ∞] or x > -3/10

<h3>What are the domains of a function?</h3>

The domain of a function is the set of input values the function can take i.e. the set of values the independent variable can assume?

<h3>How to determine the domain of the functions?</h3>

<u>Function 1</u>

The function is given as:

f(x) = √4x + 6

Set the radicand greater than 0

4x + 6 > 0

Subtract 6 from both sides

4x > -6

Divide by 4

x > -3/2

Express as interval notation

[-3/2, ∞)

Hence, the domain of f(x) = √4x + 6 is [-3/2, ∞) or x >-3/2

<u>Function 2</u>

The function is given as:

g(x) = -4√-20x - 6

Set the radicand greater than 0

-20x - 6 > 0

Add 6 to both sides

-20x > 6

Divide by -20

x < -6/20

Simplify

x < -3/10

Express as interval notation

(-∞, -3/10]

Hence, the domain of g(x) = -4√-20x - 6 is (-∞, -3/10] or x < -3/10

<u>Function 3</u>

The function is given as:

f(x) = 15 + √5x - 16

Set the radicand greater than 0

5x - 16 > 0

Add 16 to both sides

5x > 16

Divide by 5

x > 16/5

Express as interval notation

[16/5, ∞)

Hence, the domain of f(x) = 15 + √5x - 16 is [16/5, ∞) or x >16/5

<u>Function 4</u>

The function is given as:

p(x) = √20x + 6

Set the radicand greater than 0

20x + 6 > 0

Subtract 6 from both sides

20x > -6

Divide by 20

x > -6/20

Simplify

x > -3/10

Express as interval notation

(-3/10, ∞]

Hence, the domain of p(x) = √20x + 6 is (-3/10, ∞] or x > -3/10
