Sine and cosine (and trigonometric functions in general) are used extensively in physics, and neither really has priority - it depends on the particular problem you're working on. Is there a particular problem that prompted your question?
Answer:
<h3><u>Part A</u></h3>
Dimensions of tank:
- width = 8.75 in
- length = 8.75 in
- height = 23 in
⇒ Volume of each tank = width × length × height
= 8.75 × 8.75 × 23
= 1760.9375 in³
<h3><u>Part B</u></h3>
Given:
- Hot coffee density = 5.8 oz/in³
- Cold coffee density = 3.5 oz/in³
mass = density × volume
⇒ mass of hot coffee = 5.8 oz/in³ × 1760.9375 in³
= 10213.44 oz (nearest hundredth)
⇒ mass of cold coffee = 3.5 oz/in³ × 1760.9375 in³
= 6163.28 oz (nearest hundredth)
<h3><u>Part C</u></h3>
Convert the masses of the tanks from ounces to pounds
1 lb = 16 oz
⇒ mass of hot coffee tank = 10213.44 ÷ 16
= 638.34 lb (nearest hundredth)
⇒ mass of cold coffee tank = 6163.28 ÷ 16
= 385.21 lb (nearest hundredth)
If the table can hold a maximum of 800 lb:
hot coffee: 800 lb ÷ 638.34 lb = 1.25 (nearest hundredth)
cold coffee: 800 lb ÷ 385.21 lb = 2.08 (nearest hundredth)
Therefore, either:
- 1 tank of hot coffee <u>OR</u>
- 2 tanks of cold coffee
can be placed on a table which can support a maximum weight of 800 lb
It's A.
All you need to do is plug in the X from the ordered pair, then solve.
y=-5x-4
y=-5(10)-4
y=-50-4
y=-54
Which is NOT -52, so the answer is indeed A
