What are the solutions of this quadratic equation? 2^2=16x-65

Karo-lina-s [1.5K]

Answer:

x= 4.3125

Step-by-step explanation:

2^2 = 16x - 65

4= 16x- 65

+65 +65

69 = 16x

69/16 =16x/16

4.3125 = x

Arrange the numbers in increasing order 14.204 14.200 14.240 14.210

Crank

Answer:

Arranging the numbers in increasing order is 14.200, 14.204, 14.210, 14.240.

Step-by-step explanation:

Given : Numbers 14.204, 14.200, 14.240, 14.210.

To find : Arrange the numbers in increasing order ?

Solution :

Arrange the numbers in increasing order is defined as arranging numbers from the smallest number to the largest number.

If we see the numbers 14.204, 14.200, 14.240, 14.210.

The number before decimal is same so we arrange according to after decimal,

14.200<14.204<14.210<14.240

Therefore, Arranging the numbers in increasing order is 14.200, 14.204, 14.210, 14.240.

Find f(g(x)) and g(f(x)) 1. F(x) = X²-3x+1 g(x)=5x-7

Mariana [72]

We are given the following functions

$\begin{gathered} f(x)=x^2-3x+1 \\ g(x)=5x-7 \end{gathered}$

Let us first find f(g(x)

Substitute x = 5x - 1 into the function f(x) and simplify

$\begin{gathered} f(g(x))=(5x-7)^2-3(5x-7)+1 \\ f(g(x))=(25x^2-2\cdot5x\cdot7+49)^{}-15x+21+1 \\ f(g(x))=25x^2-70x+49^{}-15x+22 \\ f(g(x))=25x^2-70x-15x+49+22 \\ f(g(x))=25x^2-85x+71 \end{gathered}$

Now let us find g(f(x))

Substitute x = x² - 3x + 1 into the function g(x) and simplify

$\begin{gathered} g(f(x))=5(x^2-3x+1)-7 \\ g(f(x))=5x^2-15x+5-7 \\ g(f(x))=5x^2-15x-2 \end{gathered}$

Therefore, f(g(x) and g(f(x)) are

$\begin{gathered} f(g(x))=25x^2-85x+71 \\ g(f(x))=5x^2-15x-2 \end{gathered}$

Que frações equivalentes a 3/4 tem denominador 65

LuckyWell [14K]

Dada fração: 3/4

Necessidade de converter o denominador em 65.

Vamos supor que x deve estar no numerador (topo) das frações para obter 65 no denominador (abaixo) para obter a fração equivalente de 3/4.

Vamos definir uma atribuição.

$\frac{3}{4}=\frac{x}{65}$

Deixe-nos resolvê-lo por x agora.

Na multiplicação cruzada, obtemos

4x = 195.

Dividindo ambos os lados por 4, obtemos

x = 48.75

Assim, podemos fazer uma fração equivalente de 3/4, colocando 48.75 no topo do denominador 65.

Então, temos $\frac{48.75}{68}$
