Mathematics
1 answer:
Slav-nsk [51]2 years ago
4 0

Answer:

x = -5/6

Step-by-step explanation:

Since it is on the unit circle  

  x^2   +  ( -sqrt(11)/6)^2    = 1 ^2     (pythagorean theorem)

x^2 = 1 - 11/36

x^2  = 25 /36

x =   +-5/6       since x is in Q III  it is the negative

if the area of a rectangle is 5 5/8 centimeters square in the width is 1 1/4 centimeters what is the length of the rectangle
raketka [301]
5 5/8= 5.625
1 1/4= 1.25
Arectalgle is Area= (length)(width) so fill in what you know.
5.625= (L)(1.25)
Divide both sides by 1.25
4.5=L
So 4 1/2 cm is the length

En cuál de los siguientes procedimientos se resuelven sin error las siguiente operaciones?
myrzilka [38]

D. \frac{(8)\cdot (-7)\cdot (6)}{(-4)\cdot (-2)\cdot (-3)} = \frac{-336}{-24} = 14

Por álgebra, recordamos los siguientes dos teoremas llamados teorema del signo para productos:

(-x)\cdot y = x\cdot (-y) = -x\cdot y, \forall \,x,y\in \mathbb{R} (1)

(-x)\cdot (-y) = x\cdot y, \forall \,x,y\in \mathbb{R} (2)

Basados en la información dada en la imagen y los teoremas descritos arriba, el producto del numerador debe ser negativo y el producto del numerador debe ser también negativo, más el resultado de la división debe ser positiva.

Por tanto, la opción D representa a la operación libre de errores.

Which equation represents the partial sum of the geometric series?
kati45 [8]

Answer:

Option 1

Step-by-step explanation:

Given expression representing the partial sum of the geometric series,

\sum_{n=1}^{n=4}(125)(\frac{1}{5})^{n-1}

Expression that represents the sum of a geometric series is,

\sum_{n=1}^{n}(a)(r)^{n-1}

Here, n = number of terms

a = first term

r = common ratio

By comparing both the expressions,

n = 4

a = 125

r = \frac{1}{5}

From the given options,

Option 1

First term 'a' = 125

Common ratio 'r' = \frac{25}{125} = \frac{1}{5}

Number of terms 'n' = 4

Therefore, Option 1 will be the correct option.
