Answer:
[tex]\displaystyle f^{-1}(x)=\frac{x-3}{2}[/tex]
Step-by-step explanation:
The Inverse of a Function
The procedure to find the inverse of the function is:
* Write the function as a two-variable equation:
y = 2x + 3
* Solve the equation for x.
y - 3 = 2x
[tex]\displaystyle x=\frac{y-3}{2}[/tex]
* Swap the variables:
[tex]\displaystyle y=\frac{x-3}{2}[/tex]
Write back into function form. This is the inverse function:
[tex]\mathbf{\displaystyle f^{-1}(x)=\frac{x-3}{2}}[/tex]

Two sides of a triangle have the following measures Find the range of possible measures for the third side 19 and 25
Answer should be
__< x <__
Answers
Answer:
The range of possible values for third side is:
[tex]44>x>6[/tex]
Step-by-step explanation:
Given side lengths are:
19 and 25
Let x be the third side
Then according to the triangle in equality theorem that sum of two sides has to be greater than third side,
The inequalities will be:
[tex]19+25>x\\25+x>19\\19+x>25[/tex]
We have to solve these inequalities to find the range
So,
[tex]19+25> x => 44>x\\25+x>19 => x >19-25 => x>-6\\19+x>25 => x> 25-19 => x>6[/tex]
We have to exclude the solution with negative value because the length of a triangle cannot be negative so from the other two inequalities x has to be less than 44 and greater than 6
Hence,
The range of possible values for third side is:
[tex]44>x>6[/tex]

Consider the following binomial experiment: A newspaper publisher claims that 52% of the people in a certain community read his newspaper. Doubting the assertion, a competitor randomly surveys 289 people in the community. Find the standard deviation of this experiment, if the newspaper publisher's claim is correct.
a) 8.1932
b) 8.3932
c) 8.4932
d) 8.6932
e) 8.5932
f) None of the above.
Answers
Answer:
[tex]SD = 8.4932[/tex]
Step-by-step explanation:
Given
[tex]Sample\ Size (n) = 289[/tex]
[tex]proportion, p= 52\%[/tex]
Required
Determine the standard deviation (SD)
The standard deviation of a binomial distribution is calculated as thus:
[tex]SD = \sqrt{np(1-p)}[/tex]
Substitute values for n and p
[tex]SD = \sqrt{289 * 52\% * (1-52\%)}[/tex]
Convert to decimals
[tex]SD = \sqrt{289 * 0.52 * (1-0.52)}[/tex]
[tex]SD = \sqrt{289 * 0.52 * 0.48}[/tex]
[tex]SD = \sqrt{72.1344}[/tex]
[tex]SD = 8.49319727782[/tex]
[tex]SD = 8.4932[/tex] --- approximated
Hence, the calculated standard deviation is approximately 8.4932

Triangle ABC is an isosceles triangle with angle B as the vertex angle. Find the perimeter if AB = 6x + 3, BC = 8x - 1, and AC = 10x - 10. Perimeter = ______ units
Answers
Answer: If triangle ABC is an isosceles triangle, angle B is the vertex angle, AB=6x+3 BC=8x-1 and AC=10x-10 find x and the measures of each side of the triangle
ABC is an isosceles triangle, angle B is the vertex angle..hence BA=BC..or..AB=BC...hence...
6x+3=8x-1
8x-6x=3+1=4
2x=4
x=4/2=2
so the 3 sides are
AB=6x+3=6*2+3=12+3=15
BC=8x-1=8*2-1=16-1=15
AC=10x-10=10*2-10=20-10=10
(sorry if i got ur answer wrong)
:(
The value of the perimeter of the given isosceles triangle with a vertex at B will be 40 units.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
As per the given isosceles triangle with vertices, ABC is drawn below.
Since B is the vertex thus BA = BC
6x + 3 = 8x - 1
2x = 4
x = 2
So, AB = 6(2) + 3 = 15
BC = 8(2) - 1 = 15
AC = 10(2) - 10 = 10
Perimeter = 15 + 15 + 10 = 40 units.
Hence "The value of the perimeter of the given isosceles triangle with a vertex at B will be 40 units".

The rate of change of revenue (in dollars per calculator) from the sale of x calculators is R′(x)=(x+1)ln(x+1)R ′ (x)=(x+1)ln(x+1). Find the total revenue from the sale of the first 12 calculators. (Hint: In this exercise, it simplifies matters to write an antiderivative of x+1 as (x+8)2/2(x+8) 2 /2 rather than x2/2+x.)x 2 /2+x.)
Answers
Answer:
Total revenue = [tex]\frac{169}{2}\ln(13)-\frac{169}{4}[/tex] dollars
Step-by-step explanation:
[tex]R'(x)=(x+1)\ln(x+1)[/tex]
Integrate with respect to [tex]x[/tex].
[tex]R(x)=[/tex] ∫[tex](x+1)\ln(x+1)[/tex] dx
Take [tex]x+1=u[/tex]
Differentiate with respect to [tex]x[/tex]
[tex]dx=du[/tex]
So,
[tex]R(x)=[/tex] ∫[tex]u\ln(u)\,du[/tex]
Use integration by parts: ∫f g dx = f∫ g dx-∫(∫g dx)f' dx
Therefore,
[tex]R(x)=[/tex] [tex]\frac{u^2}{2}\ln(u)[/tex] [tex]-[/tex] ∫[tex]\frac{u^2}{2}\frac{1}{u}\,du[/tex]
= [tex]\frac{u^2}{2}\ln(u)[/tex] [tex]-[/tex] ∫[tex]\frac{u}{2}\,du[/tex]
Put [tex]u=x+1[/tex]
[tex]R(x)= \frac{(x+1)^2}{2}\ln(x+1)-\frac{(x+1)^2}{4}[/tex]
To find total revenue from the sale of the first 12 calculators, put [tex]x=12[/tex]
[tex]R(x)= \frac{(12+1)^2}{2}\ln(12+1)-\frac{(12+1)^2}{4}\\\\= \frac{(13)^2}{2}\ln(13)-\frac{(13)^2}{4}\\\\=\frac{169}{2}\ln(13)-\frac{169}{4}[/tex]
Total revenue = [tex]\frac{169}{2}\ln(13)-\frac{169}{4}[/tex] dollars
