Answer:
A = 4.6 cm
Step-by-step explanation:
Here, we want to find the length of the apothem, given the side lengths
Mathematically, we have this as;
A = s/2 tan (180/n)
where in this case;
s is the length of the sides which is 16 cm
n is the number of sides (since it is hexagon, we have this as 6)
Substituting these values;
A = 16/2 * tan (180/6)
A = 8 * tan 30
A = 4.62
To the nearest tenth, A is 4.6 cm

how do you know of an exponential fuction is reflected across the x-axis?
Answer:
Step-by-step explanation:
A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)
For example:
[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .
If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis
However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.
Hope this helps!
Ms. Smith and Mr. Roberts are running a race. Ms. Smith runs 8, 305 feet. Mr. Roberts runs 2 miles. How many feet further does Mr. Roberts run? (Reminder: 1 mile = 5,280 feet)
Answer:
Mr. Roberts runs 2,255 more feet then Ms. Smith.
Step-by-step explanation:
So I took 5,280 + 5,280 = 10,560 so now I can just take Ms. Smith's 8,305 and subtract it from 10,560 which gave me 2,255 so Mr. Roberts runs 2,255 more feet then Ms. Smith.

Answer
[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]
Step by Step Explanation
Given
See attachment for table
Required
Determine the sinusoidal function
The sinusoidal function is represented as:
[tex]y = A \sin(Bx + C) + D[/tex]
Where
[tex]|A| = Amplitude[/tex]
And it is calculated as:
[tex]A = \frac{1}{2}[Highest - Least][/tex]
From the table:
Highest = 77 and Least = 21
So:
[tex]A = \frac{1}{2}[77 - 21][/tex]
[tex]A = \frac{1}{2}[56][/tex]
[tex]A = 28[/tex]
B is calculated as:
[tex]Period = \frac{2\pi}{B}[/tex]
The period is 12 i.e. 12 months
So:
[tex]\frac{2\pi}{B} = 12[/tex]
[tex]B = \frac{2\pi}{12}[/tex]
[tex]B = \frac{\pi}{6}[/tex]
C is calculated as:
[tex]\frac{C}{B} = -4[/tex]
[tex]C = -4 * B[/tex]
[tex]C = -4 * \frac{\pi}{6}[/tex]
[tex]C = -2 * \frac{\pi}{3}[/tex]
[tex]C = -\frac{2\pi}{3}[/tex]
Lastly, D is calculated as:
[tex]D = Least + A[/tex]
So:
[tex]D =21 + 28[/tex]
[tex]D=49[/tex]
So, the function is:
[tex]y = A \sin(Bx + C) + D[/tex]
[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]
Answer:
y=28 sin (pi/6 t - 7pi/6)+49

anyone know this?????
Answer:
(- 2, 1 ) and (1, 4 )
Step-by-step explanation:
Given the 2 equations
y = - x² + 5 → (1)
- x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by adding x to both sides
y = x + 3 → (3)
Substitute y = x + 3 into (1)
x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Substitute these values into (3) for corresponding values of y
x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )
x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )

find value of X in cos(3x-30°)=sin(7x+50°)
Answer:
7
Step-by-step explanation:
Given the expression
cos(3x-30°)=sin(7x+50°)
In trigonometry cosx = sin(90-x)
Hence
Cos(3x-30) = sin(90-(3x-30))
Cos (3x-30) = sin(90-3x+30)
Cos (3x-30) = sin(120-3x)
Substitute into the expression above
Sin(120-3x) = sin(7x+50)
120-3x = 7x+50
Collect like terms
-3x-7x = 50-120
-10x = -70.
x = 70/10
x = 7
Hence the value of x is 7
Sammy made her uncle a garden. The width is 6 5 7 ft and the length is 7 3 5 ft. What is the area of the garden?
Answer:
482895ft^2
Step-by-step explanation:

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1200 hours and a standard deviation of 35 hours. Using the empirical rule, determine what interval of hours represents the lifespan of the middle 68% of light bulbs.
Answer:
(1165, 1235) (hours)
Step-by-step explanation:
The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:
(1200 - 35, 1200 + 35), or
(1165, 1235) (hours)
This is an application of the Empirical Rule.
The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).
What is the standard deviation?It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.
With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.
The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:
The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;
(1200 - 35)=1165
( 1200 + 35)=1235
(1165, 1235) (hours)
Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).
