Hey don’t worry about that grade just keep practicing maths and honestly at one point you’ll start understanding the concepts trust me. Just do it a lot.
So here are my explanations
Answer:
Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. The number of 9's in the denominator should be the same as the number of digits in the repeated block.
Step-by-step explanation:
Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)
A 180 degree rotation around the origin flips the signs of x and y, so you get:
(2, 8) (6, 8) (11, 1) (7, 3)
Then a translation to the left 6 units just subtracts 6 from all the x values:
(-4, 8) (0, 8) (5, 1) (1, 3)
Those are your points! Hope this helped!
Answer:
4
Step-by-step explanation:
We'll do two things here. First remember that when a number is raised to an exponent, and the result is raised to another exponent, you can simply multiply those exponents and apply them to the base. So we can multiply -1/2 and -2/3, giving us 1/3, which is what we'll raise 64 to.
The other thing to remember is that a fractional exponent is the same as a root of that base. So raising a number to the power of 1/3 just means we want the cube root of that number.
Applying those and we get:

If u use a calculator the answer would be zero
