I think the system of inequalities could be the following, but I'm not positive:
l=Length, w=Width
l < 12
w x l < 30
Answer: The significance of the number 82.75 in the equation = amount charged per acre in the park.
Step-by-step explanation:
Given: The Green Lawns Company uses the equation C=82.75a+56 to determine the amount to charge for mowing a city park, where a is the number of acres in the park and C is the cost in dollars.
In linear equation y=mx+c, = rate of change of y with respect to x.
Here Coefficient of a = rate of change of C with respect to a.
i.e. Coefficient of a =amount charged per acre in the park.
Hence, The significance of the number 82.75 in the equation = amount charged per acre in the park.
OK, so this is assuming we are considering that the first three kids to solve ARE NOT in the first day.
So we have 3 kids and it doubles
Day 1 : 6
Day 2 : 12
Day 3 : 24
Day 4 : 48
Day 5 : 96
Day 6 : 192
Day 7: 384
So it should take 7 days or a week to solve all the problems.
The equation:
(3 * 2)^x = 384
Answer:
A. y = sine (x + 90 degrees)
Step-by-step explanation:
- y = cosine(x) is a curve that crosses the y-axis at y = 1 and completes one cycle at 360 degrees.
- sine(x) have the same curve than cosine(x), but translated 90° to the right respect cosine(x)
- f(x + c) translates f(x) horizontally c units to the left.
- Then, sine(x + 90) is equivalent to cosine(x)
Hope this is what you need
