False, all integers are rational because they can be expressed as a fraction. Like -4 is a rational number because it can be -4/1. All integers are rational.
Answer:
C
Step-by-step explanation:
Quadratic model is shaped like a "U", or a parabola
Quartic model is shaped like a "W", highest degree is 4 (x^4).
Linear model is a line.
Cubic model is x^3, shaped like a curvy snake.
Looking at the graph, it <em>clearly</em> shows a line. So, linear model is the answer.
C is the correct answer.
P = -2x^2 + 8x + 2
for maximum P, dP/dx = 0
dP/dx = -4x + 8 = 0
4x = 8
x = 2
The company should produce 2,000 units per week to earn maximum profit.
Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10
Therefore, the maximum weekly profit is $1,000.
Answer: A
Step-by-step explanation:
Take the root of both sides and solve.
Since density is mass/volume, the density is 5 g/ml. Hope this helps!
