1 answer:

5 0

3. Sqrt of 40

4. Sqrt of 148

Distance formula is sqrt of (x-x1)^2+(y-y1)^2

So (-4-2)^2+ (3-5)^2

(-6)^2+(-2)^2

36+4

Sqrt of 40

Do the same process for 4!

Ps don’t forget to keep the square root

How do i tell if y=x^3+x^2 is even or odd?

Effectus [21]

If a function is even, then f(-x) = x.

If a function is odd, then f(-x) = -x.

y = x³ + x² → f(x) = x³ + x² → -f(x) = -(x³ + x²) = -x³ - x²

f(-x) = (-x)³ + (-x)² = [(-1)(x)]³ + [(-1)(x)]² = (-1)³x³ + (-1)²x²

= -1x³ + 1x² =-x³ + x²

f(-x) ≠ f(x) and f(-x) ≠ -f(x)

y = x³ + x² is not odd and not even

Answer: neither

Mika rides his bike 3 miles each way to his friend's house. He leaves his house at 4 p.m. How many miles does he ride his bike t

marusya05 [52]

Answer:

How many miles does he ride his bike there and back?

6 miles.

What information is extra?

The hour at which he leaves his house.

Step-by-step explanation:

We know that he rides 3 miles each way.

Then he rides 3 miles from his house to his friend's house, and another 3 miles from his friend's house to his house.

So he rides 3 miles both times, if we add that, we get:

3 miles + 3 miles = 6 miles

So:

How many miles does he ride his bike there and back?

6 miles.

And to answer the other question, we need to look at the given information that we did not use in this calculation. In this case, is the hour at which he leaves his house.

Notice that we never did use the fact that he leaves his house at 4 p.m.

Then:

What information is extra?

The hour at which he leaves his house.
