Answer:
B. 26,606.63
Step-by-step explanation:
The area of Gateway National Recreation Area is about twenty-six thousand, six hundred six and sixty-three hundredths. Which shows this number in standard form? A. 26,606.3 B. 26,606.63
C. 26,660.63 D. 26,666.3
Solution
Break down and writing in numerals of twenty-six thousand, six hundred six and sixty-three hundredths.
Twenty six thousand = 26,000
Six hundred six = 606
Sixty - three hundredth = 0.63
Adding
26,000 + 606 + 0.63
We have
26,606.63
The correct answer is B
Black line (a) -
x = -2
Purple line (b) -
x = 3
Blue line (c) -
y = 6
Green line (d) -
y = -3
Red line (e) -
Not sure
1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1
