Celsius = (Fahrenheit -32) * (5/9)
Celsius = (90 -32) * (5/9)
Celsius = (58) * (5/9)
Celsius = 32.22 degrees

A guitar string vibrates back and forth 88 times in 1 minute. what is its period in seconds?
Alchen [17]

Answer:

1.5 times per second

(1 time per second if rounded to a whole number)

Step-by-step explanation:

1 minuet is equal to 60 seconds

Because you are given 88 vibrations in one minute, you will divide 88 by 60 seconds. You want your answer in seconds.

88/60 gives us 1.466666667 on a calculator

So the guitar gives a vibration of 1.466666667 per second

If we round this, we get 1.5 vibrations per second

Or, if we round 1.4666 to a whole number then it is 1 vibration per second

Factor: 3x4y3 – 48y3
kati45 [8]

Answer:

3y3(x2 + 4)(x + 2)(x -2)

Step-by-step explanation:

3x4y3– 48y3.

= 3y3(x4 – 16).

= 3y3[(x2)2 - 42].

= 3y3(x2 + 4)(x2 - 4).

= 3y3(x2 + 4)(x2 - 22).

= 3y3(x2 + 4)(x + 2)(x -2).

Solve the equation and show your work. Tell whether it has one solution, an infinite number of
pav-90 [236]

Hello!

To solve any algebraic equation, you need to use SADMEP. SADMEP is an acronym for subtraction, addition, division, multiplication, exponents and parentheses. Our goal is to isolate the variable, x.

24 - 4x = 15 - 3x + 10 - x (simplify)

24 - 4x = 25 - 4x (subtract 24 from both sides)

-4x = 1 - 4x (add 4x to both sides)

1 = 0

This equation has no solutions because 1 and 0 are <u>never equal</u> to each other, which means that this is identified to be neither because it <u>has no real solutions</u>.

Porfabor necesito ayuda en la esta pregunta. ¿Encuentra cuatro pares ordenados de la siguiente función? f(x) = X3 – 2X2 – 2
zlopas [31]

Answer:

(0, -2), (1, -3), (2, -2) y (3, 7) son pares ordenados de f(x) = x^{3}-2\cdot x^{2}-2.

Step-by-step explanation:

Un par ordenado es un elemento de la forma (x,f(x)), donde x es un elemento del dominio de la función, mientras f(x) es la imagen de la función evaluada en x. Entonces, un par ordenado que está contenido en la citada función debe satisfacer la siguiente condición:

La imagen de la función existe para un elemento dado del dominio. Esto es:

x \rightarrow f(x)

Dado que f(x) es una función polinómica, existe una imagen para todo elemento x. Ahora, se eligen elementos arbitrarios del dominio para determinar sus imágenes respectivas:

x = 0

f(0) = 0^{3}-2\cdot (0)^{2}-2

f(0) = -2

(0, -2) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

x = 1

f(1) = 1^{3}-2\cdot (1)^{2}-2

f(1) = -3

(1, -3) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

x = 2

f(2) = 2^{3}-2\cdot (2)^{2}-2

f(2) = -2

(2, -2) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

x = 3

f(3) = 3^{3}-2\cdot (3)^{2}-2

f(3) = 7

(3, 7) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

(0, -2), (1, -3), (2, -2) y (3, 7) son pares ordenados de f(x) = x^{3}-2\cdot x^{2}-2.
