4. It can be helpful to consider the identities related to each of the answer choices.
• cot(θ) = 1/tan(θ) . . . . 1/tan(θ) + tan(θ) ≢ 1

• sec(θ) = 1/cos(θ), csc(θ)=1/sin(θ) . . . . 1/cos(θ)² + 1/sin(θ)² =
    (sin(θ)²+cos(θ)²)/(sin(θ)²cos(θ)²) = 1/(sin(θ)²cos(θ)²) ≢ 1

• sec(θ) = 1/cos(θ), tan(θ) = sin(θ)/cos(θ) . . . . (sin(θ)/cos(θ))² ≡ sin(θ)²×1/cos(θ)²
  tan(θ)² = sin(θ)²×sec(θ)² is the correct choice

• sec(θ) = 1/cos(θ), tan(θ) = sin(θ)/cos(θ) . . . . cos(θ)² ≠ 1/cos(θ)²×(sin(θ)/cos(θ))²


1. cot(290°) = -tan(20°) ≈ -0.36
  The second selection is a better choice.

There are 12 cookies in a container. There are 12 containers packed in a box for shipping. There are 12 boxes loaded onto a ship
mamaluj [8]

Option A

Total number of cookies on a shipping truck when 12 boxes are loaded is 1728.

<u>Solution:</u>

Need to determine correct option of total number of cookies on the truck

From given information

Number of cookies in 1 container = 12  

Number of container in 1 box = 12  

So number of cookies in 1 box = number of cookies in 12 container  

\Rightarrow \text { Number of cookies in } 1 \text { box }=\text { number of cookies in } 1 \text { container } \times 12

=12 \times 12=144

Number of boxes loaded onto 1 shipping truck = 12  

So Number of cookies onto 1 shipping truck = number of cookies in 12 boxes

\Rightarrow \text { Number of cookies onto } 1 \text { shipping truck }=\text { number of cookies in } 1 \text { box } \times 12

=144 \times 12=1728

Hence total number of cookies on a shipping truch when 12 boxes are loaded is 1728. Thus option A is correct

Hey can you please help me posted picture of question
zavuch27 [327]
A relation can be a function if an x value is not paired with more than y-values.
The x and y values are flipped when finding an inverse.

So, if in the inverse function a y value is paired with more than one x values, this will mean that in the function an x-value was paired with more than one y-values.

Looking at the graph we can say that no y-value in the inverse is paired with more than one x values, so the original relation would be a function.

So the answer is TRUE

25 gallons of gas were pumped into two different size tanks. Express the amount of gas pumped into the smaller tank in terms of
ioda

Answer:

The expression of amount of gas is s=25-g.

Step-by-step explanation:

Given:

25 gallons of gas were pumped into two different size tanks.

Now, to express the amount of gas pumped into the smaller tank in terms of the amount g pumped into the larger tank.

Let the amount of gas pumped into smaller tank be s.

And according to question, the amount of gas pumped into larger tank is g .

Total amount of gas pumped into both size tanks = 25 gallons.

So, to express the amount of gas pumped into the smaller tank in terms of the amount g pumped into the larger tank:

s+g=25

<em>Subtracting both sides by </em>g<em> we get:</em>

s=25-g.

Therefore, the expression of amount of gas is s=25-g.
