If n = 10, then which of the following represents 552?a)5n + 2b)5n2 + ...
Explanation:

To find the value of 552 when n = 10, we need to substitute the value of n into each expression and evaluate them one by one.

Let's evaluate each option:

a) 5n + 2:
Substitute n = 10
5(10) + 2 = 50 + 2 = 52

b) 5n2 + 2:
Substitute n = 10
5(10)^2 + 2 = 5(100) + 2 = 500 + 2 = 502

c) 5n2 + 5n + 2:
Substitute n = 10
5(10)^2 + 5(10) + 2 = 5(100) + 5(10) + 2 = 500 + 50 + 2 = 552

d) 5n3 + 5n + 2:
Substitute n = 10
5(10)^3 + 5(10) + 2 = 5(1000) + 5(10) + 2 = 5000 + 50 + 2 = 5052

e) 5n4 + 5n + 2:
Substitute n = 10
5(10)^4 + 5(10) + 2 = 5(10000) + 5(10) + 2 = 50000 + 50 + 2 = 50052

Conclusion:

From the calculations above, we can see that option c) 5n2 + 5n + 2 evaluates to 552 when n = 10. Therefore, the correct answer is option c).

If n = 10, then which of the following represents 552?a)5n + 2b)5n2 + ...
To solve this problem, recall that 102 = 100. Therefore since n = 10, n2 = 100. The number 552 can be broken up into 500 + 50 + 2, which can be written as 5(100) + 5(10) + 2. Again, since n = 10 and n2 = 100, 5(100) + 5(10) + 2 = 5n2 + 5n + 2.

Similar ACT Doubts

In a physics class, students conducted a series of experiments by placing different objects into a beaker of water. They conducted twenty trials for each object. For each trial, they recorded whether or not the object floated.First, they placed a steel paper clip into the water. They observed that the paper clip usually sank; however, they also saw that occasionally, the paper clip stayed afloat if it was placed very gently on top of the water. Next, they repeated the the same procedure using a cork, a toy boat made of aluminum, and a glass marble. They observed that both the cork and the toy boat always stayed afloat in the water, but that the glass marble always sank.Below, three students give their explanations for these observations.Student 1:Objects float when they are less dense than the liquid in which they are immersed. For example, when immiscible liquids of varying densities are mixed together in a container, the most dense liquid will sink to the bottom of the container, while the least dense liquid will rise to the top. This same principle applies to solid objects. Because the cork and the aluminum toy boat always float, cork and the aluminum of the boat must be less dense than water. Because the glass marble always sinks, the glass of the marble must be more dense than water.Objects that are more dense than water can also float due to surface tension. Surface tension occurs because molecules of a liquid are more attracted to each other more than they are to other objects. Molecules on the surface of water are attracted to the molecules around them and below them. This attraction causes a liquids surface to behave if it were covered by a thin film, which resists penetration by other objects. Therefore, small objects such as paper clips can sometimes float on water when the upward force of waters surface tension exceeds the force of gravity pulling such objects down. Because the paper clips often sink and only float sometimes, we can conclude that they are indeed more dense than water, and that their floating is due to surface tension.Student 2:Objects float in two different cases: when they are buoyed by a liquids surface tension or when their average density is less than that of the liquid in which they are immersed. The average density of cork is less than that of water. This is why the cork floats. In contrast, the density of glass is more than that of water. This is why the glass marble sinks.However, the densities of aluminum and of steel are greater than that of water. Thus, density cannot be used to explain why the aluminum toy boat and the paper clip float. Both of these objects float because of surface tension. Because the paper clip does not have much mass, the normal upward force created by waters surface tension can be enough to allow it to float. Other objects with greater mass, like the toy boat, employ a particular shape to magnify the force of surface tension. The curved shape of the boats bottom both stabilizes the boat and increases the amount of the boats surface area that touches the water, maximizing the force due to surface tension that the boat receives.Student 3:In this experiment, the paper clip floats because of surface tension; however, the cork, toy boat, and marble float or sink because of their relationship to a buoyant force. All objects immersed in a liquid experience a buoyant force, which pushes them upward. The strength of this force is equal to the weight of the liquid displaced, or pushed aside, by an object. Every object also experiences a downward force due to gravity, which is measured as the objects weight, and which is directly proportional to the objects mass. When the buoyant force acting on an object is greater than the downward force due to gravity, the object floats. However, when the buoyant force is less than the force due to gravity, the object sinks. Both the cork and the aluminum toy boat are able to displace enough water to create a buoyant force that exceeds the force due to gravity, so they float. However, the glass marble does not displace enough water to create a sufficient buoyant force, so it sinks.Q.Paint is more dense than cooking oil; however, when a drop of paint is dripped into a container of cooking oil, it floats on top of the oil. If Student 1s explanation is correct, which of the following is most likely the reason for this observation?
