How many solutions does the equation have? a+5=1/5(5a+25)

1 answer:

6 0

A + 5 = $\frac{1}{5}$ (5a + 25)

First, simplify $\frac{1}{5} (5a + 25)$ to $\frac{5a+25}{5}$ / Your problem should look like: $a + 5 = \frac{5a+25}{5}$
Second, multiply both sides by 5. / Your problem should look like: $5a + 25 = 5(a + 5)$
Third, expand to get rid of parenthesis. / Your problem should look like: $5a + 25 = 5a + 25$
Fourth, both sides are equal, resulting it having infinite solutions.

Answer: infinite solutions

Find (fºg)(1) f(x) = x² - 1 g(x) = √x A.0 B.1 C.4 √2 D. √8

Given:

The function are

$f(x)=x^2-1$

$g(x)=\sqrt{x}$

To find:

The value of $(f\circ g)(1)$ .

Solution:

We have,

$f(x)=x^2-1$

$g(x)=\sqrt{x}$

We need to find the value of $(f\circ g)(1)$ .

$(f\circ g)(1)=f(g(1))$ $[\because (f\circ g)(x)=f(g(x))]$

$(f\circ g)(1)=f(\sqrt{1})$ $[\because g(x)=\sqrt{x}]$

$(f\circ g)(1)=f(1)$

$(f\circ g)(1)=(1)^2-1$ $[\because f(x)=x^2-1]$

$(f\circ g)(1)=1-1$

$(f\circ g)(1)=0$

The value of $(f\circ g)(1)$ is 0.

Therefore, the correct option is A.

Bonjour à tous, pouvez vous m'aider à trouver la réponse pour cette "question ouverte" svp?

La solution:

625 cm^2.

Explication étape par étape:

Si la forme est rectangulaire, elle aura la plus grande superficie possible quand la longueur équivaut à la largeur. Pour avoir un périmètre de 100 cm, cela signifie que chaque côté doit faire 25 cm.

La superficie serait alors de 25 cm x 25 cm = 625 cm^2.
