Answer:
Domain: x>=1
Step-by-step explanation:
what values of x make it work (square roots must be greater than or equal to zero)
sqrt (5x-5) >=0
square each side
5x-5 >=0
add 5 to each side
5x>=5
divide by 5 on each side
5x/5 >=5/5
x >=1
Answer:
0,37
Step-by-step explanation:
It will be easier if we noun the events.
A= Cindi's friend comes to England.
B= New England is mostly cloudly.
We are searching the probability of just A doesn´t happen or just A happens but not B.
The probability of A doesn´t happen is one minus the probability of A:

The events A and B are independent for this reason the probability than both occurs is the product of the probability of each event. It means:

The probability of A doesn´t happen or A and B happen is:

Conclusively we have to rest the probability of A doesn´t happen and A and B happen, but A happens and doesn´t happen and the same time is impossible. For this reason, we have the same result.

Then the probability either Cindi's friend does not come to New England, or she does come but it is mostly cloudy is 0.37
Answer:
7ft 1in.
Step-by-step explanation:
add the two 6 ft together and that gives you 12 ft. then add 7 in + 6 in which gives you 13 in. There are 12 in a foot, so you take 12 away from the 13 giving you 1 in remaining and 1 additional foot to add to the 12.
Answer:
<h3>1/2</h3>
Step-by-step explanation:
Given the limit of the function expressed as;

To take the limit, we nee to divide through by the highest power of n first

Hence the limit of the the nth term as n becomes increasingly large is 1/2
Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
- x intercepts: (-3,0),(5,0)
- y intercept: (0,-15)
The graph is below.
