What are the zeros of the graphed function y = 1/3 (x + 3)(x + 5)?

Mathematics

One factor will be zero, hence y will be zero, when x=-3.

The other factor will be zero, hence y will be zero, when x=-5.

The zeros of the function are x ∈ {-5, -3}.

_____

This solution makes use of the "zero product rule," which states a product is zero if and only if one or more factors is zero.

Andrea rode her bike 3 23rds miles on saterday and 4 56 miles on sunday. how far did she bike in all​
Tpy6a [65]

Answer:

8 1/2 miles

Step-by-step explanation:

Please use " ' " to indicate fractions:

Andrea rode her bike 3 2/3 miles on saturday and 4 5/6 miles on sunday.

Add together 3 2/3 and 4 5/6.  The LCD is 6, so 3 2/3 should be rewritten as 3 4/6.  Now 3 4/6 and 4 5/6 have the same denominator, 6.

 3 4/6

+4 5/6

-----------

 7  9/6.    Note that 9/6 = 1 1/2, so rewrite

7  9/6 as 8 3/6, or 8 1/2.

She biked 8 1/2 miles in all.

0.2.0.4, 0.6, 0.8, 1....<br> Arithmetic or geometric
Basile [38]

Arithmetic sequences have a common difference between consecutive terms.

Geometric sequences have a common ratio between consecutive terms.

Let's compute the differences and ratios between consecutive terms:

Differences:

0.4-0.2 = 0.2,\quad 0.6-0.4=0.2,\quad 0.8-0.6=0.2,\quad 1-0.8=0.2

Ratios:

\dfrac{0.4}{0.2}=2,\quad \dfrac{0.6}{0.4} = 1.5,\quad \dfrac{0.8}{0.6} = 1.33\ldots, \quad\dfrac{1}{0.8}=1.25

So, as you can see, the differences between consecutive terms are constant, whereas ratios vary.

So, this is an arithmetic sequence.
