Answer:
-29
Step-by-step explanation:
substitute the y and x values whith there given values
so 1/3-2(3)-4(-1)2
first simplify (-1)2 or (-1)(-1) which is 1 so now the equation is 1/3-2(3)-4(1)
now you must solve all the values that have multiplying involved so you have 1/3-6-4
now subtract 6 and 4 to get 1/3-10
now find the LCD which is 3
multiply the LCD by both terms to get 1-30 which equals -29
I am pretty sure it's a trick question because none of them are irrational
8x + 10 = 10x - 6
2x = 16
X = 8
Measure 1 is 74
Measure 3 is 74
Measure 4 is 180-74=106
1. so just subsitute numbers if we subsitute 5 for x then we get 0 if it's height is 6 then the time will be 16
2. so you want to factor the equation and get f(x)=x^2-4x-5=(x-5)(x+1) then set this equation = to 0 so (x-5)(x+1)=0
x-5 or x+1 must equal 0 so
x-5=0
x=5
x+1=0
x=-1
discard this because you cannot yield a negative ammount
so when the bank yields 5 in a day, the income is 0
You can write 2311 and 3912 in the form :
Then
Taken modulo 20, the terms containing powers of 20 vanish and you're left with
We further have
so we end up with
and so .
###
If instead you're trying to find , you can apply Euler's theorem. We can show that using the Euclidean algorithm. Then since , and 8 divides 3912, we have
To show 2311 and 20 are coprime:
2311 = 115*20 + 11
20 = 1*11 + 9
11 = 1*9 + 2
9 = 4*2 + 1 => gcd(2311, 20) = 1
