Answer:
center at (6, -4) r = √7
Step-by-step explanation:
(x – 6)^2 + (y + 4)^2 = 7
This is in the form
(x – h)^2 + (y - k)^2 = r^2
Where (h,k) is the center of the circle and r is the radius of the circle
Rearranging the equation to match this form
(x – 6)^2 + (y -- 4)^2 = sqrt(7) ^2
The center is at (6, -4) and the radius is the sqrt(7)
Answer:
Exfoliation
Step-by-step explanation:
Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.
Answer:
The correct answer is D) 4/5 and 40/50
Step-by-step explanation:
In order to find this, do the division and find the decimal answer. When they match, they are equivalent.
4/5 = .8
40/50 = .8
I’ve attached my work below for #4
5) 8% is equivalent to 8 cents so each item was $1.08
Than you know he spent 16.20 so you divided
1.08/16.20 which equals 15
So he got 15 items
6) the moon is 250,000 miles away which is about driving around earth 10 times which would take 6 months (not sure about this one)
Hope this helps!
Have a nice day :)
