Answer 1
Answer:

Answer:

The distance between points A and B is 4.47miles.

Step-by-step explanation:

Pythagoras' theorem-

It states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Here, AC is the hypotenuse and AB and BC are the two legs.

Applying the Pythagoras' theorem,

\Rightarrow AC^2=AB^2+BC^2

\Rightarrow AB^2=AC^2-BC^2

\Rightarrow AB=√(AC^2-BC^2)

\Rightarrow AB=√(6^2-4^2)=√(36-16)=√(20)=4.47
Answer 2
Answer: a^2 + b^2 = c^2\n\n 4^2 +AB^2 = 6^2 \n\nAB^2 = 6^2 -4^2\n\nAB^2 = 36-16\n\nAB^2 = 20\n\nAB = √(20) \n\nAB = \boxed {4.47}

What is the difference between 4x and x to the 4th power? Evaluate both of these expressions when x = 2

Answers

Difference between (4x)⁴      and    x⁴

= (4x)⁴                            x⁴

= 4⁴x⁴

= 256x⁴,                         x⁴

Evaluate both when x = 2

(4x)⁴   = 256x⁴ = 256*2⁴ = 256*16 = 4096

x⁴ = 2⁴ = 16.
4x is equivalent to 4 *x whereas xto the 4th power means, x times itself 4 times 
4 * 2= 8
2*2*2*2= 16 bc 2*2=4 and again 2*2=4 therefore 4*4=16
