Answer: The sentence that contains an error in apostrophe usage is the first one: “What did you do with the houseplant’s I bought yesterday?”
Explanation: The sentence “What did you do with the houseplant’s I bought yesterday?” contains an error in apostrophe usage because there should not be an apostrophe in “houseplants”. The final “s” in “houseplants” is only signaling the plural form of the word and not possession as in the genitive case; therefore, the apostrophe must be eliminated. On the other hand, the use of apostrophe in the other sentences is correct. In the second and third sentences, it has been used to indicate a contraction, while in the last sentence it has been used to show possession.
Since self-handicapping allows people to easily engage in ____, it helps them to maintain and enhance positive self-concepts. a. introspection b. the fundamental attribution error c. the self-serving bias d. the self-reference effect
Base on Piaget’s Cognitive development, this falls under Stage 1 the Sensorimotor Stage. It explains that under the ages of 18-24 months, there is a development and realization of things that they believe to are always there. In a case where wanted a specific toy and it is not placed where it used to be, they have a state of remembering which is known as the object of permanence. This is a sign that their mind is developing.
x(t) = 2.31 + 4.90t² – 0.10t⁶
If we are going to differentiate the equation in terms of x, we get the value for velocity.
dx/dt = 9.8t – 0.6t⁵
Calculate for the value of t when dx/dt = 0.
dx/dt = 0 = (9.8 – 0.6t⁴)(t)
The values of t from the equation is approximately equal to 0 and 2.
If we substitute these values to the equation for displacement,
(0) , x = 2.31 + 4.90(0²) – 0.1(0⁶) = 2.31
(2) , x = 2.31 + 4.90(2²) – 0.1(2⁶) = 15.51
Thus, the positions at the instants where velocity is zero are 2.31 and 15.51 meters.

The 2 adjacent rectangles (corrals) form one larger rectangle.
as shown in the figure, let x be the length of the fences perpendicular to the river, then the length of the side opposite to the river will be 420- 2x (yard)
so we can write the following function, which calculates the area A enclosed by the fence, as a function of x.
clearly A is a quadratic function, its graph is a parabola. This parabola looks downwards because of the minus of the term -2x
from A(x)=2x(420-2x) we can find that the x intercepts of the parabola are:
one of the roots is x=0
x=210 is the other root.
The x coordinate of the vertex is the midpoint of (0, 210), that is 210/2=105
f(105)=2*105(420-2*105)=210*(420-210=2110*210=44,100 square yard.
the highest point of the parabola is the largest value the function takes, so the maximal area of the fence.
Answer: max area= 44,100 square yard.
Correct answer is D. Comma or Period Inside Rule
A. Question mark or exclamation point inside: those are not really necessary.
B. Colon or semicolon: not, a semicolon would divide the whole sentence and it would be shorten; a colon would work but after requested, when there is already a comma.
C. Question mark or Exclamation Point Outside Rule: would not work, becase it is an very polite and affirmative sentence.
D: A comma or period inside rule: actually, just a comma would work. Please, Cooper’s dad requested, go… Cooper’s dad requested must be in between commas as it is a vocative.

Answer: The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared
Step-by-step explanation: Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.
We are to select the correct option that could be used to calculate the coordinates for point B.
Let, (x, y) be the co-ordinates of point B.
According to distance formula, the distance between two points (a, b) and (c, d) is given by
Therefore, the distance between the points A(8, 9) and B(x, y) is given by
Since, distance between A and B is 10 units, so
d = 10.
Thus, the correct statement is
10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.
Option (C) is correct.
Answer: The answer is (C) Patricia is not correct because both 3 – 4i and -11+√2i must be roots.
Step-by-step explanation: Given that (-11-√2i) , (3 + 4i), and 10 are the roots of the polynomial function f(x) that Patricia is studying.
We know that the complex roots of a polynomial function always occur in pairs. That is, if (a + bi) is a root of a function, then (a – bi) will also be a root (one is the complex conjugate of the other).
The complex conjugate of (3 + 4i) is (3 – 4i) and the complex conjugate of (-11 – √2i) is (11 + √2i).
Therefore, (3 – 4i) and (-11 + √2i) both are the roots of f(x).
Hence, since we have 5 roots, so the degree of the polynomial function f(x) cannot be 4.
Since Patricia concludes that the degree of f(x) is 4, so she is not correct because both (3 – 4i) and (-11+√2i) must be roots.
Thus, option (C) is correct.

The error in grammar: it help
Correct verb form: it helps
In the simple present tense, third-person singular pronouns, like she, he and it, use conjugated verbs formed by the base form of a verb and the affix -s, -es, or -ies. For example: helps, thinks, cries, watches. In the excerpt provided, the error is in the verb help because it is not correctly conjugated for the pronoun it: it is missing an s at the end.
There’s nothing that I dreamt of more,
Than to jump aboard a great big ship,
A telescope, a map, a sword, by my hip,
To feel the sea breeze in my hair,
To stroke my parrot on the wood chair,
To be bold and brave and happy as can be,
To trek and travel and sail the seven seas.

1) Perpedicular lines form a 90° angle between them.
2) The product of the slopes of two any perpendicular lines is – 1.
So, from that basic knowledge you can analyze each option:
a.Lines s and t have slopes that are opposite reciprocals.
TRUE. Tha comes the number 2 basic condition for the perpendicular lines.
slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.
b.Lines s and t have the same slope.
FALSE. We have already stated the the slopes are opposite reciprocals.
c.The product of the slopes of s and t is equal to -1
TRUE: that is one of the basic statements that you need to know and handle.
d.The lines have the same steepness.
FALSE: the slope is a measure of steepness, so they have different steepness.
e.The lines have different y intercepts.
FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.
f.The lines never intersect.
FALSE: perpendicular lines always intersept (in a 90° angle).
g.The intersection of s and t forms right angle.
TRUE: right angle = 90°.
h.If the slope of s is 6, the slope of t is -6
FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.
So, the right choices are a, c and g.
The correct answer is D. The North American Free Trade Agreement or NAFTA is signed in 1994. by Canada, Mexico, and the United States, making a trilateral trade bloc in North America. It is going to replaced by the 2018 United States, Mexico, Canada Agreement. Since it is a trade agreement, it is supposed to increase trade between these countries which will result in the increased production. Donald Trump said that he was pulling out of NAFTA and that would have a range of consequences for the U.S. including reduced access to the export markets, reduced economic growth, and increased prices for gasoline, cars, fruits, and vegetables.

A. All college professors have master’s degrees. Oren is a college professor, so he must have a master’s degree is the best example of deductive reasoning
Logical reasoning is process of using a rational, systematic of steps based on mathematical procedures and given statements to arrive at a conclusion. There are two basic forms of logical reasoning which most associated with mathematical thinking: Deductive and inductive reasoning
Deductive reasoning is the reasoning process from one or more statements to reach logically certain conclusion.
The differences between deductive reasoning and inductive reasoning is, inductive reasoning moves from specific instances into generalized conclusion, whereas deductive reasoning moves from generalized principles which known true to a true and specific conclusion.
For example, the premise “Every A is B” can be followed by another premise, “This C is A.” and these will be lead to the conclusion “This C is B.”
All college professors have master’s degrees. Oren is a college professor, so he must have a master’s degree is the best example of deductive reasoning, because
All college professors have master’s degrees = All A have B
Oren is a college professor = C is A
He must have a master’s degree = C is B.

No, the events “brown hair” and “brown eyes” are not independent.
The table that represents the hair and eye colors of thirty students of the fifth grade are given in table as:
Brown hair Blonde hair Total
Green eyes 9 6 15
Brown eyes 10 5 15
Total 19 11 30
No, the events “brown hair” and “brown eyes” are not independent.
Since, two events A and B are said to be independent if:
where P denotes the probability of an event.
Here we have:
A= students having brown hair.
B= students having brown eyes.
A∩B= students having both brown hair and brown eyes.
P(A)=19/30 (ratio of addition of first column to the total entries)
P(B)=15/30 ( ratio of addition of second row to the total entries)
P(A∩B) ≠ P(A)×P(B)
Hence, the two events are not independent.
The correct answer to the question is : By increasing the pressure.
Before answering this question, first we have to understand Gay lussac’s law.
As per Gay lussac’s law, the pressure of a gas increases or decreases by 1/273 th of its pressure at zero degree celsius; for every 1 degree celsius rise or fall of temperature at constant volume
In a simple way, the pressure is directly proportional to absolute temperature.
Mathematically P ∝ T. [ P = pressure and T = temperature]
Hence, increase in pressure at constant volume may increase its temperature.
