How to find the side of a rhombus with given diagonals?

1 answer:

7 0

The diagonals of a rhombus are perpendicular bisectors of each other. You can use the Pythagorean theorem. If the diagonals are length "a" and "b", the side length of the rhombus (s) is
s = (1/2)√(a²+b²)

given that sine theta = 0, and cosine theta is less than zero, find the exact values of the other two trig functions

vekshin1

Answer:

θ = π + periods of 2π

Sin (π + 2π) = 0

Cos (π + 2π) = -1

Tan (π + 2π) = 0

Step-by-step explanation:

Sin (θ)=0 implies that θ only can be 0 or π plus periods of 2π:

θ = 0+2π

θ = π+2π

For Cos(θ) the values only can be:

Cos (0+2π) = 1 and

Cos (π+2π) = -1

from this, only Cos (π+2π) < 0

So θ only can be θ=π+2π

Determine if the graph is a function then state the domain and range.

nignag [31]

<h3>Explanation</h3>

A function is a set of relation that doesn't have repetitive domain. If we want to know if a graph is function or not, we have to do the line test.

Line Test

Draw a vertical line. Make sure that a line passes through a graph.
See if a line intercepts a graph more than one point or just only one.

Result

If a line intercepts a graph more than one point, it is not a function.

However, if a line only intercepts a graph just one point, it is indeed a function.

The given graph from the question is a function because it passes line test.

Domain and Range

Domain is the set of all x-values, meaning we only focus on x-axis or x-value only.

Range is the set of all y-values. We only focus on y-value or y-axis for Range.

Determine Domain from Graph

We can simply say that the domain is from starting domain or x-coordinate point to end x-coordinate point. For example, if a graph starts at x = -4 and ends at x = 2, we can say that - 4<=x=2.

Determine Range from Graph

Similar to Domain except Range starts from the minimum value or point to the maximum point or value. For example if a graph starts at min point = 6 and max point = 9. We can say that 6<=y<=9.

From the graph, the domain starts from negative infinity to positive infinity. Meaning that x can be any numbers. Hence, the domain is set of all real numbers. For range, the minimum value is 0 and max value is positive infinity. Therefore we write y>=0.

<h3>Answer</h3>

 $\begin{cases} x \in \mathbb{R} \\ y \geqslant 0 \end{cases}$ 

Domain is set of all real numbers.

Range is greater or equal to 0.

Whats the answer will give brainliest solve for x

Mkey [24]

X = arctan(32/19)

x = 59.30 degrees.

You don't say if the answer needs to be rounded, so round it as needed.
