When we want to know if the diagonals or sides are congruent we would use the D. Slope.

<h3>What is congruent?</h3>

It should be noted that congruent in geometry simply means when two objects have same shapes and size.

In this case, when we want to know if the diagonals or sides are congruent we would use the slope. This can show the equality in the shape.

Determine whether the given length can be side lengths of a right triangle. 12m, 60m, 61m
Ne4ueva [31]

Answer:

No

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.

The longest side = 61, thus

61² = 3721

12² + 60² = 144 + 3600 = 3744 ≠ 3721

Thus these sides do not form a right triangle.

A music buff wants to estimate the percentage of students at a midwestern university who believe that elvis is still alive. how
gulaghasi [49]
Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50

so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)

The margin of error for population proportion is calculated as:

E=z* \sqrt{ \frac{p(1-p)}{n} }  \\  \\ &#10; \frac{E}{z} = \sqrt{ \frac{p(1-p)}{n} }  \\  \\ &#10;( \frac{E}{z} )^{2}= \frac{p(1-p)}{n} \\  \\ &#10;n= p(1-p)* (\frac{z}{E})^{2}  \\  \\ &#10;n=271

This means 271 students should be included in the sample

Which value of x does not satisfy the equation sin^2x + sin x = 0
zzz [600]

Answer:

x \neq 0 \pm \pi \cdot i, \forall i \in \mathbb{N}_{O} and x \neq \frac{3\pi}{2}\pm 2\pi \cdot j, \forall j \in \mathbb{N}_{O}.

Step-by-step explanation:

The equation can be simplified with the help of trigonometric identities:

\sin x \cdot (\sin x + 1) = 0

Which means that equation is equal to zero if any component of the product is zero. The solutions of the expression are:

a) \sin x

x = 0 \pm \pi\cdot i,\forall i \in \mathbb{N}_{O}

b) \sin x + 1

\sin x + 1 = 0

\sin x = -1

x = \frac{3\pi}{2} \pm 2\pi\cdot i,\forall i \in \mathbb{N}_{O}

Any value different of both subsets do not satisfy the equation described above.
