What is DEF ?
Is it a straight line ?
Is it a line that's bent in two places ?
Is it a triangle ?
Is there a picture ?
Do you have a drawing ?
Could you describe it for us ?
IF DEF is a triangle, then all three angles add up to 180 degrees.
The angles take 2 shares, 4 shares, and 4 shares of the 180.
There are (2 + 4 + 4) = 10 shares all together.
So each share is (180 / 10) = 18 degrees.
The angles are:
-- 2 shares = (2 x 18) = 36 degrees
-- 4 shares = (4 x 18) = 72 degrees
-- 4 shares = (4 x 18) = 72 degrees .
None of this means anything unless DEF is a triangle.
Hello,
Let's assume the last digit given by the function last(x).
last(7^0)=1
last(7)=7
last(7^2)=last(49)=9
last(7^3)=last(last(7^2)*7)=last(9*7)=last(63)=3
last(7^4)=1
If the exponent n is 0,4,8,12,.... a multiple of 4 last(7^n)=1
If the exponent n is 1,5,9,13,.... a multiple of 4 + 1 last(7^n)=7
If the exponent n is 2,6,10,14,.... a multiple of 4 + 2 last(7^n)=9
If the exponent n is 3,7,11,15,.... a multiple of 4 + 3 last(7^n)=37
Here exponent is 282=70*4+2
last(7^282)=9
This sets up as a very commonly used proportion.
90 oz / 18.95 = 1 oz / x Cross multiply
90 x = 18.95 Divide by 90
x = 18.95 / 90
x = 0.21 dollars or 21 cents.
So each ounce of shampoo costs 0.21 dollars or 21 cents.
This is a very handy way to check best deals. Stores have trained us for years to believe that the more we buy of a brand, the better the price. It isn't always true. Sometimes buying the smaller quantity is the better deal. There is only one way to be sure and that's to do a proportion like this one.
Try this is an example. The same company makes a smaller container of shampoo of 45 oz for 9.15. How much is 1 oz and which is the better deal? You should get 0.20333 dollars so this is marginally (just) the better deal.
Step-by-step explanation:
g(x) = (x - 3)²
g(-9) = (-9 - 3)²
g(-9) = (-12)²
g(-9) = 144
6 inches would be the answer
