Answer:
A = 40°
B = 50°
Step-by-step explanation:
If cos A = sin B, then A + B = 90
So, 2x/3 + 20 + 2x - 10 = 90
2x + 60 + 6x - 30 = 270
8x + 30 = 270
8x = 240
x = 30
2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40
2x - 10 = 2(30) - 10 = 60 - 10 = 50 or 90 - 40 = 50
A) 1.00
Just look at where the slope crosses 2 miles and then look left on the y-axis where the price is given
Answer:
The function is represented by .
Step-by-step explanation:
In this case, we must observe that total cost of the dog () is the sum of two components: i) <em>Fixed cost</em> () - Adoption fee, ii) <em>Variable cost</em> () - Daily cost of feeding the dog, both measured in US dollars.
In addition, we suppose that variable cost is directly proportional to the number of days that Kirstin owns her dog. That is:
Where:
- Number of days that Kirstin owns her dog, measured in days.
- Daily feeding costs, measured in US dollars per day.
If , then:
The function is represented by .
