Y-k = a(x-h)²; h and k are given vertex(0,3), then
y -3 = a(x-0)²→ y = ax² + 3. From the table we can calculate a:(for x =1, y=2)
2 =a(1²) +3→ 2= a + 3 and a = -1, hence the equation:
y = -x². It's a parabola open downward with a max at (0,3)
y' = - 2x: This is the equation of the tangent with a rate of change = -2
Another way:
For x = 8, y₁'= -16. For x = 9, y₂' = -18
y'₂ - y'₁ = -18 + 16→ rate of change = -2
Answer:
64 feet squared
Step-by-step explanation:
8*8=64
X=20
26+13+1+8=58
X=2 so 58/2 is 29 so x is 29. And to find the vz you just plug it in 29 into the equation 2x+1 2(29)+1=59
Answer:
The second answer is correct
Answer:
E
Step-by-step explanation:
\sqrt 6 is an irrational number, as it cannot be written as the ratio of 2 numbers.
It is also a real number, as it does not include the square root of a negative number.
Therefore, E is the correct option.
