Answer:
Rate of Change = -77.9 feet/year
My interpretation: "Is Bad."
Step-by-step explanation:
The rate of change is the number of feet that Lake Powell dropped, divided by the number of years the drop took place. We want a value with a unit of feet/year.
<u>Year</u> <u>Feet</u>
1999 3893
2005 3425.6
<u>Change</u>
Year = (2005 - 1999) or 6 years
Feet = (3425.6 - 3893) or -467.4 feet
Rate of Change = (-467.4 feet)/(6 years)
Rate of Change = -77.9 feet/year
=======================
FYI: Lake Powell is 22.39 feet lower today (June 23, 2022) than it was 1 year ago.
Plug in random values for x and find y value
assume x = 10 then y = 430
Express as ordered pair:(10,430)
First you take -3 and add itself to get 6x = -48. Then you simply divide 6 into -48 and you get x = -8
so a normal diff of squares is (a^2-b^2)
factored it is
(a+b)(a-b)
and we know when exponents are multiplied together they’re added, so if you know that the b value is a square of a number, then look at the exponent
look at 1 y^4 is a square since y^2 x y^2 = y^4
and 144 is the square of 12
both terms can be square rooted and there is a - sign, meaning a diff of squares:
(y^2-12)(y^2+12)
the second one is the only one that is not a difference of squares
sorry i know i’m bad at explaining things
