Here is a table of values y=f(x).
Mariulka [41]

A. <u>False.</u> 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.  <u>True.</u> 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. <u>True.</u> 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. <u>False.</u> Looking at the table, when x=0, f(x)=3. This is another way of saying that f(0)=3, which is <em>not </em>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} .
