Andreas93 [3]

Answer:

cos60° = $\frac{1}{2}$

Step-by-step explanation:

Using the cofunction identity

• cos(90 - x)° = sinx°, hence

sin30° = cos(90 - 30)° = cos60° = $\frac{1}{2}$

irakobra [83]

<h2>Answer:</h2>

First of all, let's define what a function is:

A function $f$ from a set $A$ to a set $B$ is a relation that assigns to each element $x$ in the set $A$ exactly one element $y$ in the set $B$ . The set $A$ is the domain (also called the set of inputs) of the function and the set $B$ contains the range (also called the set of outputs).

The ordered pairs has been plotted below. As you can see, the set B is the only relation that meets the requirements of the concept of function because that relation assigns each element $x$ in the set $A$ exactly one element $y$ in the set $B$ . For the other sets, at least one element $x$ in the set $A$ matches to two or more elements $y$ in the set $B$ .

the length of a rectangular patio is 7 feet more than its width, w The area of the patio A(w),can be represented by the function

lesya692 [45]

The area of the patio A(w), can be represented by the function that will be A(w) = w² + 7w.

<h3>What is the area of the rectangle?</h3>

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The length of a rectangular patio is 7 feet more than its width (w).

The area of the patio A(w),can be represented by the function

Length (L) = w + 7

Then the area will be

A(w) = (w + 7)w

A(w) = w² + 7w

More about the area of the rectangle link is given below.
