<h3>Amount of sand craig and Alissa collect together at one time is 1.4 pounds</h3>
<em><u>Solution:</u></em>
Given that,
Craig and Alissa are building a sandcastle on the beach. They each have a bucket
Craig's bucket holds 1/2 pound of sand and Alissa's bucket holds 9/10 pound of sand
Therefore,
<em><u>How much sand can craig Alissa collect together at one time</u></em>
Add both, we get
Thus, amount of sand craig and Alissa collect together at one time is 1.4 pounds
B has the equation -2 + 7 = -5
C has the equation -7 + 5 = -2
D has the equation 5 + (-7) = -2
4/5 is the right answer.....
He first two are relatively easy. f(x-2) shifts it sideways (2 to the right in this case) f(x) -2 shifts it straight down (by 2)
f(2x) means replace x with 2x in the original 4(2x + 1)^2 − 3 if you factor out the 2 from the square root you get 4*sqr(2) ( x + ½)^2 - 3 which is now in the form a ( x -h)^2 + k the vertex is now at (-½, -3) (it used to be at (-1,-3) the "a" has gotten bigger, which makes the parabola "skinnier" (it goes up faster)
2•f(x) becomes 2*( 4(x + 1)2 − 3 ) = 8 (x+1)^2 -6 where is the vertex now? is this parabola fatter or skinnier than the original f(x) ?
