Answer:
c
Step-by-step explanation:
Any ride takes $2.00 and one mile takes $0.20.
Cost = $0.20 + $2.00
Cost = $2.20
Theorem of Pythagoras: a²+b²=c², where a, b is legs and c is hypotenuse.
We've got one leg known, let it be a=sqrt 3,
and the hypotenuse - c=2sqrt3
Putting these into the theorem, we get an equation: (sqrt3)²+b²=(2sqrt3)² . Solving it, we get:
3+b²=4*3
3+b²=12
b²=9
This equation has two possible roots: b=3 and b=-3. Since this is a triangle, there can't be a side with a negative value => b=3.
The answer is a. 3
The answer is 40 cause 4 times 9 = 36 so juat add the 0 to 4 and it makes it 40 times 9 ='360
The fifth root of 32 is 2
In other words,
![\sqrt[5]{32} = 2](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B32%7D%20%3D%202)
It's similar to stating that 7^2 = 49 can be transformed into saying sqrt(49) = 7 where "sqrt" is shorthand for "square root"
The general rule is
![x^n = b \ \ \longleftrightarrow \ \ \sqrt[n]{b} = x](https://tex.z-dn.net/?f=x%5En%20%3D%20b%20%5C%20%5C%20%20%5Clongleftrightarrow%20%5C%20%5C%20%20%5Csqrt%5Bn%5D%7Bb%7D%20%3D%20x)
Answer:
k= 8/5
Step-by-step explanation:
here x= 5 and y= 8
we have y=kx
k= y/x
k= 8/5 this is constant of variation
