What’s all input for f(x)=3

defon

Answer:

all inputs are equal to <u>3</u>

Step-by-step explanation:

$f(x) = 3 \\ = 3 \times 1\\ = 3 \times {x}^{0} \\ anything \: raised \: to \: 0 \: is \: 1 \\$

$\\ substituting \: any \: value \\ \: of \: x \: in \: f(x) \\ f(3) = 3 \times {3}^{0} \\ = 3 \times 1 \\ = 3 \\$

$\\ similarly \: all \: values \: of \: x \: will \\ give \: 3$

Dy/dx = y/x , y(1) = −2

s2008m [1.1K]

Start with

$\dfrac{dy}{dx}=\dfrac{y}{x}$

Separate the variables:

$\dfrac{dy}{y} = \dfrac{dx}{x}$

Integrate both parts:

$\displaystyle \int \dfrac{dy}{y} = \int\dfrac{dx}{x}$

Which implies

$\log(y) = \log(x)+c$

Solving for y:

$y = e^{\log(x)+c} = e^{\log(x)}e^c=xe^c$

Since $e^c$ is itself a constant, let's rename it $c_1$ .

Fix the additive constant imposing the condition:

$y(1) = c_1\cdot 1 = -2\iff c_1=-2$

So, the solution is

$y(x) = -2x$

Design for a library has a scale of 1/3 inch equals 1 foot. The height of library in the drawing is 12 inches. Whats the actual

liberstina [14]

So we know 1/3 of an inch is the same as 1 foot. Which is 12 inches.

So it's easier to calculate, we can say that 1/3*3 = 1. Therefore, we don't have to deal with fractions.

This means that we need to multiply 3 * 12 = 36 to find out how many 1/3's we need. So multiply 1/3 by 36 to double-check:

1/3 * 36 = 12.

The question is asking us the actual height. And we know 1 foot = 1/3 inches.

1 * 36 = 36 feet.

Another way to do it is, we know that there are 3 1/3's to get to 1. Which means it's 3 feet IRL. We know we gotta multiply by 12 to get to 12, so

3*12 = 36.
