Answer:

C. sin(90° - θ)

Step-by-step explanation:

A trig function of an angle equals the cofunction of the angle's complement.

The cofunction of  cosine is sine, and the complement of θ is 90° - θ.

∴ cosθ = sin(90° - θ)

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

\cos \theta

We need to find the correct cofunction identity for it.

Cofunction identities represent the relationship among the trigonometric functions.

The value of trigonometric function of an angle is equal to cofunction of its complement.

As we know that sine is a complement of cosine.

so, it becomes,

\cos \theta=\sin(90^\circ-\theta)

Hence, Option 'C' is correct.

Follow the steps to solve this equation. 3(2x + 6) – 4x = 2(5x – 2) + 6 1. Use the distributive property: 6x + 18 – 4x = 10x – 4
Yuliya22 [10]

Answer:

x=2.

Step-by-step explanation:

We have been given an equation 3(2x+6)-4x=2(5x-2)+6. We are supposed to solve our given equation step by step.

Step 1: Use the distributive property.

3\cdot 2x+3\cdot 6-4x=2\cdot 5x-2\cdot 2+6

6x+18-4x=10x-4+6

Step 2: Combine like terms.

6x-4x+18=10x-4+6

2x+18=10x+2

Step 3: Use subtraction property of equality:

2x-2x+18-2=10x-2x+2-2

16=8x

Step 4: Use the division property of equality:

\frac{16}{8}=\frac{8x}{8}

2=x

Therefore, the solution of our given equation is x=2.

Robin wants to find out the number of salamanders by a pond near her house. She catches 45 of them, puts a leg band on each sala
Verdich [7]
Given:
1st week: caught 45 salamanders and put leg bands on them
2nd week: caught 50 salamanders and 3 have leg bands

3/50 = 0.06 of the salamander population have leg bands.

45 / 0.06 = 750 total number of salamanders 

<span>45/750 = 0.06 or 6% </span>

The reasonable estimate of the number of salamanders by the pond is 750 salamanders.
