I, sorry but that problem does not make any sense how do 5x-6 tell me?
Answer:
Step-by-step explanation:
sen(x)=0.5
3cos(x)-4cos^3(x)=0
Remember:
cos^3(x)=cos(x)*cos^2(x)
3cos(x)-4(cos(x)*cos^2(x))=0
we have :
cos^2(x)=1-sin^2(x)
Then:
3cos(x)-4(cos(x)*(1-sin^2(x)))=0
sin^2(x)=(0.5)^2=0.25
3cos(x)-4(cos(x)*(1-0.25))=0
3cos(x)-4(cos(x)*(0.75))=0
Finally
3cos(x)-3cos(x)=0
Answer:
x = 1
Step-by-step explanation:
4x - 5/5 = 3
4x - 1 = 3
add 1 to each side of the equation:
4x = 4
divide both sides by 4:
x = 1
Answer:
Either $7040 or $220
Step-by-step explanation:
Scenario A
In this sentence, 10 miles isn't important.
First, you do how much money do you get per trip.
32 x 11 = 352
And there is 20 of this
352 x 20 = 7040
Scenario B
If you get $ 11.00 per trip the 10 miles and the passengers won't matter
20 x 11 = 220
In order to simplify a fraction, we have to find a common factor in both numerator and denominator. So, let's start by factor the expressions completely: at the numerator we have
![a^2-3a = a(a-3)](https://tex.z-dn.net/?f=%20a%5E2-3a%20%3D%20a%28a-3%29%20)
At the denominator we have
![a^3-8a^2+12a = a(a^2-8a+12) = a(a-2)(a-6)](https://tex.z-dn.net/?f=%20a%5E3-8a%5E2%2B12a%20%3D%20a%28a%5E2-8a%2B12%29%20%3D%20a%28a-2%29%28a-6%29%20)
So, the fraction can be written as
![\dfrac{a(a-3)}{a(a-2)(a-6)}](https://tex.z-dn.net/?f=%20%5Cdfrac%7Ba%28a-3%29%7D%7Ba%28a-2%29%28a-6%29%7D%20)
You can see that there is a factor
in common, that can be simplified:
![\dfrac{a(a-3)}{a(a-2)(a-6)} = \dfrac{a-3}{(a-2)(a-6)}](https://tex.z-dn.net/?f=%20%5Cdfrac%7Ba%28a-3%29%7D%7Ba%28a-2%29%28a-6%29%7D%20%3D%20%5Cdfrac%7Ba-3%7D%7B%28a-2%29%28a-6%29%7D%20)
