symmetry for y=x²+2
Answer:
x=0
Step-by-step explanation:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b/2a
in our case
y=x^2+2
a=1 b=0 c=2
so x=-b/2a=-0/2*1=0
x=0 is axis of symmetry
Answer:
Step-by-step explanation: 7 b and d8
Answer:
15 and 20
Step-by-step explanation:
When dividing 88 by 5 we wil have;
88/5
= 17 3/5
= 17 + 0.6
= 17.6
So we are to find the two numbers that 17.6 falls in between
From the given option 17.6 falls between 15 and 20. Hence the required numbers are 15 and 20
Answer:
Step-by-step explanation:
2(2) + (2)^3 - 1/2(2)^2
4 + 8 - 1/2(4)
4 + 8 - 2
12 - 2 = 10
The exponential function representing the bacteria population after t hours is f(t) = 2000 * e^(ln(0.5)/3 * t).
To find the exponential function that represents the size of the bacteria population after t hours, we can use the formula N = N0 * e^(kt), where N0 is the initial population, e is Euler's number (approximately 2.71828), k is the growth/decay constant, and t is the time in hours.
In this case, the initial population N0 is 2,000 and the population after 3 hours is 1,000. Plugging these values into the formula, we get:
N = 2000 * e^(3k) = 1000
Solving for k, we find k = ln(0.5)/3. Therefore, the exponential function representing the bacteria population after t hours is f(t) = 2000 * e^(ln(0.5)/3 * t).

The exponential decay function representing the bacteria population after t hours is f(t) = 2000 × 0.5^(t/3), where t is the number of hours passed.
The student has observed a population of bacteria decreasing from 2,000 to 1,000 over three hours and seeks an exponential function to model the decay of the population over time, expressed as f(t). Since the population is halving every three hours, we can represent this with the function f(t) = 2000 × 0.5^(t/3), where 2000 is the initial population, 0.5 represents the halving, and t is the time in hours. The exponent (t/3) is used because the halving occurs every three hours.
