Answer:
Math teachers face three major challenges: Their beliefs about teaching and learning, their content and pedagogy knowledge, and time for reflection.
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
4x⁶-9 = (2x³)² - (3)²
If the range of the numbers in the list L is 4, then x can't be 4 since there is an element in the list that is x^2. Therefore,
0 ≤ x^2 ≤ 4 so that it would be the highest number and
0 ≤x ≤ 2
So, the value of x can be equal to 2 but not higher. So, 2 is always greater or equal to x.
Answer:
9,400
Step-by-step explanation:
12,846 - 3,467 = 9,379
The hundreds digit is 3.
So, you look to the left of the digit and if it is 5 for more you add a number to the 3 and make the rest of the digits 0s. But if it below 5, then you leave the 3 alone and make the rest of the digit going to the right 0s.
Then, your answer is (9,400)

Answer:
The center is (-10,10) and the radius is 4sqrt(3)
Step-by-step explanation:
(x + 10)^2 + (y - 10)^2 = 48
We can write the equation of a circle as
(x -h)^2 + (y - k)^2 = r^2 where (h,k) is the center and r is the radius
(x- -10)^2 + (y - 10)^2 = (sqrt(16*3) )^2
(x- -10)^2 + (y - 10)^2 = (4sqrt(3)) ^2
The center is (-10,10) and the radius is 4sqrt(3)
