What are expressions? Help
slavikrds [6]

Answer:

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Step-by-step explanation:

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations, and other aspects of logical syntax. Many authors distinguish an expression from a formula, the former denoting a mathematical object, and the latter denoting a statement about mathematical objects.

If the diagonals of a rhombus are 10 and 24, find the area of the rhombus.
Ede4ka [16]
In a rhombus, the diagonals meet at right-angles and also cut each other in two equal halves, like in the picture below.

now, notice the upper-right triangle on the side there, it has a height of 12 and a base of 5, and as you know the area of a triangle is 1/2 bh, so you'd know what the area of that one is.

well, there are 4 equal triangles with that much area, so sum them up, and that's the area of the rhombus.

Complete Question

A sensor output was acquired for 32 seconds at a rate of 200 Hz and spectral analysis was performed using FFT. If the data set was split into 5 segments (each 6.4 seconds long), what is the resulting:

a)F minimum

b) F maximum

c) Frequency resolution

Answer:

a) Fmax=100Hz

b) Fmin=0Hz

c) F_r=0.0313

Step-by-step explanation:

From the question we are told that:

Time t=32sec

FrequencyF=200Hz

Segments \mu=5

Generally the equation for Frequency Range is mathematically given by

Fmax=\frac{F}{2}

Fmax=100Hz

Therefore

a) Fmax=100Hz

b) Fmin=0Hz

c)

Generally the equation for Frequency Resolution is mathematically given by

F_r=\frac{F}{N}

Where

N=The Total dat points

N=Sampling Frequency *Time

N=200*32

N=6400

Therefore

F_r=\frac{200}{6400}

F_r=0.0313

La edad de Alejandro equivale a las dos quintas partes de la edad de Andrea. Si la suma de
Mariana [72]

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

En esta pregunta debemos traducir el enunciado en ecuaciones algebraicas y resolver el sistema resultante. Tras una lectura cuidadosa tenemos el siguiente sistema de ecuaciones:

y = \frac{2}{5}\cdot x (1)

x + y = 56 (2)

Donde:

  • x - Edad de Andrea, en años.
  • y - Edad de Alejandro, en años.

A continuación, procedemos a resolver el sistema:

(1) en (2):

x + \frac{2}{5}\cdot x = 56

\frac{7}{5}\cdot x = 56

7\cdot x = 280

x = 40

Por (1):

y = \frac{2}{5}\cdot 40

y = 16

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

A. side AB = 38/3 units B.m∠VYX =77°

Step-by-step explanation:

A.A rhombus has its four sides equal. This means side AB=side CD

Given that AB=5x+1 and CD=2x+8  equate the two sides to find value of x as;

5x+1=2x+8

collect like terms

5x-2x=8-1

3x=7

x=7/3

side AB = 5x+1

AB= 5*7/3 +1

AB=35/3 +1

AB=35/3 +3/3 = 38/3

B.

The diagonals of a rhombus intersect to form 90°

Hence

(3n²-0.75)°=90°

3n²=90°+ 0.75°

3n² =90.75° -----dividing by 3 both sides

n² =90.75°/3 =30.25°

n²=30.25°

n=√30.25°

n=5.5°

so angle Z =90°

and angle ZVW =(9n+2)°

∠ZVW = (9*5.5 +2 )° =51.5°

In a rhombus all four sides are equal, thus side VY = YX.This means triangle VYX is an isosceles triangle.

Hence angle ∠YVZ=∠WVZ =51.5°, and because VYX is an isosceles triangle then ∠YXV =51.5° so

∠VYX= 180°-(51.5°+51.5°)

          =180°-103°=77°
