Here is a table of values y=f(x).

Mariulka [41]

A. False. The range of $f(x)$ is the set of values it can produce. In the table, $f(x)$ produces values from $0$ to $3$ . However, the range of all real numbers is all rational numbers, basically from $-\infty$ to $\infty$ , not just a few numbers in-between. So, the range of $f(x)$ is not all real numbers.

B. True. Looking at the table, when $x=-3$ , $f(x)=2$ . This is another way of saying that $f(-3)=2$ , which is what B is saying.

C. True. The domain of $f(x)$ is the set of values of $x$ that produce some output in $f(x)$ . Looking at the table, all of the $x$ values listed on it are in the set $\{-5, -3, 0, 2, 6, 7, 9, 10, 13\}$ , which is what C is saying.

D. False. Looking at the table, when $x=0$ , $f(x)=3$ . This is another way of saying that $f(0)=3$ , which is not what B is saying.

Find the solution of the given initial value problem in explicit form. y' = (1 – 11x)y?, y(0) = -1 Enclose numerators and denomi

Tanya [424]

Answer:

$y(x)=-e^{x-(\frac{11*x^{2} }{2}) }$

Step-by-step explanation:

This is a separable equation. First divide both sides by y:

$\frac{dy(x)}{\frac{dx}{y(x)} } =-11x+1\\\frac{dy}{y}=(-11x+1)dx$

Integrate both sides:

$\int\ \frac{dy}{y} \ =\int\ (-11x+1) \, dx$

$log(y)=-(\frac{11*x}{2} )+x+ c_1$

Solve for y taking exp to both sides:

$y(x)=c_1*e^{x-(\frac{11*x^{2} }{2}) }$

Where $c_1$ is an arbitrary constant

Evaluating the initial condition:

$y(0)=c_1*e^{0-(\frac{11*0^{2} }{2}) } =-1$

$c_1*e^{0} =-1\\c_1*1=-1\\c_1=-1$

Finally, replacing $c_1$ in the differential equation solution:

$y(x)=-e^{x-(\frac{11*x^{2} }{2}) }$

If a number added to five is divided by the difference of the number and two, the result is three-fourths. Find the number.

alexandr1967 [171]

Answer:

x = - 26

Step-by-step explanation:

Let the number be x.

According to the question,

$\frac{x+5}{x-2} = \frac{3}{4}\\$

Cross multiplying 4 & 3 gives :-

$4(x+5)=3(x-2)$

And solving this eqn. gives :-

$4(x+5)=3(x-2)\\=> 4x+20=3x-6\\=>4x-3x=-20-6\\=>x=-26$

Verification :-

(putting the value of x = -26 )

$\frac{x+5}{x-2} \\\\=>\frac{-26+5}{-26-2} \\\\=> \frac{-21}{-28} \\\\=>\frac{21}{28}$

Reducing $\frac{21}{28}$ by 7 gives $\frac{3}{4}$ .
