Answer:
27 x 9^3x = 3^3 x 9^3x = 3^3 x (3^3)^3x = 3^3 x 3^9x = 3 ^3+9x
3^3+9x = 3k
ln(3^3+9x) = ln(3^k)
3+9x(ln3)=k(ln(3))
k= 3(1+3x)/ln(3)
Step-by-step explanation:
ln(x^n) = n(ln(x))

The ratio of the sides of two similar hexagons is 3:4. If the area of the smaller hexagon is 36 cm2, what is the area of the larger hexagon? (A
hexagon has 6 sides)
Answer:
64 cm²
Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b , then
ratio of areas = a² : b²
Here ratio of sides = 3 : 4
ratio of areas = 3² : 4² = 9 : 16
let x be the area of the larger hexagon then by proportion
[tex]\frac{9}{16}[/tex] = [tex]\frac{36}{x}[/tex] ( cross- multiply )
9x = 16 × 36 = 576 ( divide both sides by 9 )
x = 64
Area of larger hexagon = 64 cm²

Given that the line is x/3 + y/2 =1
i ) make y the subject
ii ) gradient of line
Answer:
see explanation
Step-by-step explanation:
(i)
[tex]\frac{x}{3}[/tex] + [tex]\frac{y}{2}[/tex] = 1 ( multiply through by 6 to clear the fractions )
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide through by 3 )
y = - [tex]\frac{2}{3}[/tex] x + 2
(ii)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope ( gradient ) and c the y- intercept )
y = - [tex]\frac{2}{3}[/tex] x + 2 ← is in slope- intercept form ( that is part (i)
with gradient m = - [tex]\frac{2}{3}[/tex]

Miguel, Christian, Amber, Sophia, and Kadin eat dinner together at Texas Roadhouse. The total bill is $53.25. They decide they want to split the bill evenly.
How much should each person pay
Answer:
17.75
Step-by-step explanation:
So what we know is that we have to DIVIDE the bill evenly by the amount of people sharing the bill.
> 53.25 / 3 = ?
> 5 - 3 = 2 ( one 3 goes into 5 )
> 23 - 21 = 2 ( seven 3s goes into 23 )
> 22 - 21 = 1 ( seven 3s goes into 22 )
> 15 - 15 = 0 ( five 3s goes into 15 evenly )
> 53.25 / 3 = 17.75
So this should be your result afterwards.

is
-f(x)
the same as
f(-x)
Answer:
In general, no.
Step-by-step explanation:
f(-x) = -f(x) when the function is "odd." Such a function is symmetrical about the origin. This will not generally be the case, so, in general, -f(x) ≠ f(-x).
_____
Additional comment
When f(-x) = f(x), the function is "even." It is symmetrical about the y-axis.
Among trig functions, sin(x) is odd, and cos(x) is even.
Among polynomials, any polynomial with only odd-degree terms is odd; any polynomial with only even-degree terms is even.

Help...Question 1 Objective: Apply properties of rhombi to solve mathematical and real-world problems. Rhombus LMNO is shown with its diagonals. Angle MNO measures 119º. What is the measure of angle LMN? M P N o
Answer:
61°
Step-by-step explanation:
As in all parallelograms, adjacent angles are supplementary.
∠LMN = 180° -∠MNO
∠LMN = 180° -119° = 61°

solve the Simultaneous equations : x+y=5; x-y=1
Answer:
x=3 and y=2
Step-by-step explanation:
These equations line up quite nicely, so let's use the elimination method.
x+y=5
+ x-y=1
-------------
2x=6.
Now that we added the two equations together, we only have x as a variable to solve. We now divide 2 from both sides
x=3.
Now we take our 3 and substitute it into one of the equations. I want to put it in the first one.
3+y=5.
We subtract 3 from both sides to get y=2.
We end up with the answers x=3 and y=2. If you plug them in to check, they make sense. 3+2=5 and 3-2=1. This answer is proven to be correct.

Find the missing value given the points and slope.
(x,1) and(4,6)
m=−5
Answer:
x = 5
Step-by-step explanation:
yeah-ya...... right?
Step-by-step explanation:
the slope is the ratio y change/ x change.
it is -5 here, that means -5/1.
we see in the points that y changes +5 units (from 1 to 6). so, to get a negative slope, the x change must be negative then (and must be -1, so that we still get the slope of -5/1).
in order for the x change to be -1 when going from point 1 to point 2, the starting x of point 1 must be 4 + 1 = 5.
so, point 1 is (5, 1).
point 2 is a indicated (4, 6).

What is a function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Graph the trigonometric function using the amplitude, period, phase shift, and vertical shift.
Amplitude: 1
Period: 2π
Phase Shift: None
Vertical Shift: None
The coordinates to plot the graph are (0, 1), (π/2, 0), (π, -1),....
To find the x-intercept, substitute in 0 for y and solve for x.
To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (π/2 +πn,0), for any integer n
y-intercept(s): (0,1)
Use the derivative to find the maximum and minimum.
(0, 1) is a local maxima and (π, −1) is a local minima
Therefore, (0, 1) is a local maxima and (π, −1) is a local minima of the given function.
