Answer:
7 and 8.
Step-by-step explanation:
When we check out what is √49 and √64, we can see that they equal 7 and 8 respectively. Since √56 is between √49 and √64, we can say that √56 is between 7 and 8.
Hoped this helped.
The slope should be
m= 2/3 (2 over 3)
First term (a1) is -1
recursive formula goes like this
![a_n](https://tex.z-dn.net/?f=a_n)
is the nth term
![a_{n-1}](https://tex.z-dn.net/?f=a_%7Bn-1%7D)
is the term before that
we normally have
![a_n=f(a_{n-1})](https://tex.z-dn.net/?f=a_n%3Df%28a_%7Bn-1%7D%29)
we see each term is multipying by -3 to get next one
so that would be
![a_n=-3*a_{n-1}](https://tex.z-dn.net/?f=a_n%3D-3%2Aa_%7Bn-1%7D)
where a1=-1
the 3rd option is correct except that it is the explicit formula
so answer is 2nd one
Answer:
z = ![\frac{50}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B3%7D)
Step-by-step explanation:
The ratio of corresponding sides are equal, that is
=
( cross- multiply )
12z = 200 ( divide both sides by 12 )
z =
= ![\frac{50}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B3%7D)
