Answer:

True

Step-by-step explanation:

10•2) •3 = 60

10•(2•3) = 60

The variables are rearranged, yet without the parentheses the outcome could be faulty.

I hope this was the brainliest answer & helped you better understand!

Step-by-step explanation:

(10 x 2) x 3 = 60

10 x ( 2 x 3) = 60

They are the same. Order doesn't matter for multiplication.

F(x) = x² + 10 <br>What is the average rate of change of f over the interval [ -2,-1?

KIM [24]

Answer:

-3

Step-by-step explanation:

f(-2) = (-2)^2 + 10 = 14 -> (-2, 14)

f(-1) = (-1)^2 + 10 = 11 -> (-1, 11)

(11-14)/(-1-(-2)) = -3/1 = -3

What is the common ratio for the sequence 5,-10,20,-40?

algol [13]

Answer:

The COMMON RATIO of the sequence is -2.

Step-by-step explanation:

Here, the given sequence is:

5, -10, 20 ,-40

Here, The first term ( a 1 ) of the sequence is (5)

The second term (a 2) of the sequence is (-10)

Third term of sequence (a 3) is 20

Now, calculating the common ratio (r) of sequence ,we get:

$\frac{a_2}{a_1} = r = (\frac{-10}{5}) = -2\\\frac{a_3}{a_2} =r = (\frac{20}{-10}) = -2$

So, here r =(-2)

⇒ The COMMON RATIO of the sequence is -2.

Hence, the given sequence in in GEOMETRIC PROGRESSION.
