Note: Your exponential expression seems a little unclear. Because 27 is not an exponential expression.
But, I am assuming that your exponential expression is:
[tex]\:27^{\frac{1}{3}}[/tex]The reason is that my solution would still clear your concept about this topic, no matter what the question is.
Answer:
The simplified value of the exponential expression is:
[tex]27^{\frac{1}{3}}=3[/tex]
Step-by-step explanation:
Assuming the exponential expression
[tex]\:27^{\frac{1}{3}}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:27=3^3[/tex]
[tex]=\left(3^3\right)^{\frac{1}{3}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(3^3\right)^{\frac{1}{3}}=3^{3\cdot \frac{1}{3}}[/tex]
[tex]=3^{3\cdot \frac{1}{3}}[/tex]
[tex]=3^1[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a[/tex]
[tex]=3[/tex]
Therefore, the simplified value of the exponential expression is:
[tex]27^{\frac{1}{3}}=3[/tex]

Hey guys I have a hard time with these questions. Can someone explain it to me? :)
Answer:
Step-by-step explanation:
there are a couple ways to find slope
1. Rise over Run Method:
for this method, you use basic counting
to do this, you count the number of x spaces it takes the line to get from one y space to the next
for your line, the run is 3 because it takes 3 x spaces to get from one whole number to the next on the y spaces
you would say the rise is -1 because the line is going down, and it takes 3 x spaces to get the next pot that is on a y-axis increment
so we know the rise is -1 and the run is 3
if you put this into rise/run format, you get 1/-3
so -1/3 is you slope
2. Using the Coordinates
in this line, you see two points
the points are 1. (-1, -1), and 2. (2, -2)
using the coordinates means that you use a formula: [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
the y2 is the y value of the second coordinate (-2), the y1 is the y value of the first coordinate (-1)
the x2 is the x value of the second coordinate (2), the x1 is the x value of the first coordinate (-1)
if you plug these it you get: -2 - (-1) / 2 - (-1)
this can be simplified to -2 + 1 / 2 + 1
and simplified again to -1/3
Qhat ever method you use, you should get the same answer. Using both methods is a good way to check your work.

A car can travel 450 km in the same time it takes a train to travel 350 km. The car's average speed is 20 km/h faster than the average speed of the train. What is the average speed of the car? Give your answer to two decimal places.
I would just like help with figuring out the right equation for this word problem, because I cannot figure this out.
Answer:
The average speed of the car is 90 km/h
Step-by-step explanation:
The rule of the distance id D = v × t, where
v is the speedt is the time∵ A car can travel 450 km in the same time it takes a train to travel
350 km
→ That means the time of them are equals
∴ Time of the car = Time of the train
→ From the rule above t = [tex]\frac{D}{v}[/tex]
∵ D(car) = 450 km and D(train) = 350 km
∵ The car's average speed is 20 km/h faster than the average speed
of the train
→ Assume that the average speed of the train is x km/h
∴ v(train) = x km/h and v(car) = (x + 20) km/h
→ Use the rule of the time above to find the time of each one
∵ t(car) = [tex]\frac{450}{(x+20)}[/tex]
∵ t(train) = [tex]\frac{350}{x}[/tex]
∵ t(car) = t(train)
∴ [tex]\frac{450}{(x+20)}[/tex] = [tex]\frac{350}{x}[/tex]
→ By using cross multiplication
∵ 450 × x = 350 × (x + 20)
∴ 450x = 350(x) + 350(20)
∴ 450x = 350x + 7000
→ Subtract 350x from both sides
∴ 100x = 7000
→ Divide both sides by 100 to find x
∴ x = 70
∵ x represents the average speed of the train
∴ The average speed of the train = 70 km/h
∵ The average speed of the car = x + 20
∴ The average speed of the car = 70 + 20
∴ The average speed of the car = 90 km/h

Answer:
a) 2211.6812281 rad/min
b) 352 rpm
Step-by-step explanation:
A bicycle with 24-inch diameter wheels is traveling at 16 mi/h. Find the angular speed of the wheels in radians per minute. ___ radians per minute
How many revolutions per minute do the wheels make? (Round your answer to three decimal places.) ___ revolutions per minute
truck with 24-in.-diameter wheels is traveling at 16 mi/h.
---------
1 mile per hour = 88 feet per minute
16 mi/hr = 1408ft/minute
----------
Each revolution = pi*d feet = 4pi feet
(b) How many revolutions per minute do the wheels make?
rev/min
-------------
Each revolution = pi*d feet = 4pi feet
rpm = 1408 ft/min / 4pi feet
=~ 352 rpm
---------------
(a) Find the angular speed of the wheels in rad/min.
rad/min
-------------
rad/min = rpm*2*pi
= 352 rpm × 2× π
= 2211.6812281 rad/min
So, the wheels make [tex]224.20 \ rev/min[/tex].
Angular Sped:
Angular speed measures how fast the central angle of a rotating body changes with respect to time. It is expressed as,
[tex]\omega=\frac{\theta}{t}[/tex]
Given that:
Diameter[tex]=24 \ in[/tex]
Radius[tex]=12 \ in[/tex]
First, we have to find the angular speed([tex]\omega[/tex]):
We use the formula,
[tex]v=\omega r[/tex]
Substituting,
[tex]16 \ mi/hr=\omega \times 12 \ in[/tex] ([tex]\therefore[/tex] [tex]1mile=63360inches, \ and \ 1hour=60min[/tex])
[tex]=\frac{16 \ mi\times \left ( 63360 \ in/mi \right )}{\left ( 1 \ hr\times 60 \ min/hr \right )}[/tex]
[tex]=\omega \times 12 \ in[/tex]
[tex]\Rightarrow 15840 \ in/min=\omega \times 12 \ in[/tex]
[tex]\omega =16896/12\\w=1408 \ rad/min[/tex]
Now, we have to find rev/min:
([tex]\therefore \ 1 \ revolution=2\pi[/tex])
Thus,
[tex]1408 \ rad/min\times1 \ rev/2\pi \ rad=224.20 \ rev/min[/tex]..

A weightlifter holds a 1,300 N barbell 1 meter above the ground. One end of a 2-meter-long chain hangs from the center of the barbell. The chain has a total weight of 600 N. How much work (in J) is required to lift the barbell to a height of 2 m?
Answer: 1750J
Step-by-step explanation:
The work done that will be used to loft the barbell and the hanging chain will be:
W1 = (1300 + (1/2 × 600))
= 1300 + 300
= 1600J
The work done that'll be used in lifting the upper part of the chain will be:
W2 = (1/2 × 600) × (1/2 × 1).
= 300 × 0.5
= 150J
Total work down will be:
=W1 + W2
= 1600J + 150J
= 1750J
Find the 7th term in the following binomial expansion(4f+t/3)8 in ascending powers of t
Answer:
[tex]\displaystyle T_6=\frac{448}{729} f^2t^6[/tex]
Step-by-step explanation:
Binomial Theorem
Any power of x + y can be expanded into a sum of the form:
[tex]\displaystyle (x+y)^{n}={n \choose 0}x^{n}y^{0}+{n \choose 1}x^{n-1}y^{1}+{n \choose 2}x^{n-2}y^{2}+\cdots +{n \choose n-1}x^{1}y^{n-1}+{n \choose n}x^{0}y^{n}[/tex]
For any given term k, counted from 0 to n:
[tex]\displaystyle T_k={n \choose k}x^{n-k}y^{k}[/tex]
Note if we have to find the 7th term, we have to use k=6. The expression is:
[tex]\displaystyle \left(4f+\frac{t}{3}\right)^8[/tex]
For n=8, x=4f, y=t/3, k=6:
[tex]\displaystyle T_6={8 \choose 6}(4f)^{8-6}\left (\frac{t}{3} \right )^{6}[/tex]
[tex]\displaystyle T_6={8 \choose 6}(4f)^{2}\left (\frac{t}{3} \right )^{6}[/tex]
[tex]\displaystyle T_6={8 \choose 6}16f^2\frac{t^6}{3^6}[/tex]
Calculate:
[tex]\displaystyle {8 \choose 6}=\frac{8!}{2!\cdot 6!}=28[/tex]
Thus:
[tex]\displaystyle T_6=28\cdot 16f^2\frac{t^6}{729}[/tex]
Simplifying, the 7th term is:

Step-by-step explanation:
First you need to get the least common denominator of the left
-7 3/4 and 1/2 the LCD is 4 so...
(1/1) 3/4 = 3/4 (This doesn't have to change since the denominator is already 4)
(2/2) 1/2 = 2/4
Let's make -7 3/4 into an improper fraction = -31/4
Let's make -2 1/4 into an improper fraction = -9/4
Plug back in
-31/4 - 2w + 2/4 [tex]\leq[/tex] -9/4 (collect like terms)
-29/4 - 2w [tex]\leq[/tex] -9/4 (add 29/4 on both sides)
-2w = 5 (divide by -2)
w = -5/2 or -2 1/2

The bottom of a doorway to a building is 3.45 feet above the ground, and a ramp to the door for the disabled is at an angle of 6 degrees with the ground. How much longer must the ramp be in order to make the angle 3 degrees? Round the answer to the nearest tenth.
Answer:
The ramp should be 32.9 feet longer.
Step-by-step explanation:
When the ramp is at [tex]6^{o}[/tex] to the ground, its length can be determined by applying the appropriate trigonometric function. Let the length be represented by l, so that;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin [tex]6^{o}[/tex] = [tex]\frac{3.45}{l}[/tex]
l = [tex]\frac{3.45}{Sin 6^{o} }[/tex]
= [tex]\frac{3.45}{0.10453}[/tex]
= 33.0048
l = 33.0 feet
When the angle is reduced to [tex]3^{o}[/tex], the length of the ramp would be;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin [tex]3^{o}[/tex] = [tex]\frac{3.45}{l}[/tex]
l = [tex]\frac{3.45}{Sin 3^{o} }[/tex]
= [tex]\frac{3.45}{0.05234}[/tex]
= 65.9152
l = 65.9 feet
Change in length of ramp = 65.9 - 33.0
= 32.9
The ramp should be 32.9 feet longer.
