Step-by-step explanation:
Answer:
There are 4 $5 bill and 2 $1 bills.
the answer will be D.
make equations from given information:
Variable:
Let $5 be y and $1 be x.
solve them simultaneously:
22 - 5y = 6 - y
22 - 6 = - y + 5y
16 = 4y
y = 4
solve for x:
x + y = 6
x + 4 = 6
x = 6 - 4
x = 2
Answer:
- domain (-∞, ∞)
- range (-∞, 4]
- increasing (-∞, 0)
- decreasing (0, ∞)
- constant (only at x=0, not on any interval)
Step-by-step explanation:
The graph is of the equation y = -x^2 +4. It is a polynomial of even degree, so has a domain of all real numbers: (-∞, ∞).
The vertical extent of the graph includes y=4 and all numbers less than that:
range: (-∞, 4]
The graph is increasing to the left of its vertex at x=0, decreasing to the right.
increasing (-∞, 0); decreasing (0, ∞)
There is no interval on which the function is constant. It has a horizontal tangent at x=0, but a single point does not constitute an interval.
Answer:
The answer is 2pi
Step-by-step explanation:
To find the area of a cirlce, use the equation ( pi * r^2 ) so for a semi circle, which is half, simply divide that by 2. Plug in 2 for radius and you get 4pi/2 which simplifies to 2pi.
