By using appropriate identities, where required, determine which of the following sets of vectors in F(-o,o) are lin- early dependent. (a) 6, 3 (c) 1, sinx, sin 2x (e) (3-X)2, X2-6x, 5 (f) 0, cos'TX, sin53πX sin2 x, 2 cos2 x (b) x, cos x (d) cos 2x, sin' x, cos x
The set of vectors {x, cos(x)} is linearly independent as per the concept of linearity of vectors.
To determine if the set of vectors {x, cos(x)} in F(-∞, ∞) is linearly dependent, we need to check if there exist scalars c1 and c2, not all zero, such that c1x + c2cos(x) = 0 for all values of x in the given interval.
Let's consider a specific value of x, say x = 0.
Plugging this value into the equation, we have c1(0) + c2cos(0) = 0. Since cos(0) = 1, the equation simplifies to c2 = 0.
Now, considering another specific value of x, say x = π/2, we have c1(π/2) + c2cos(π/2) = 0. Again, cos(π/2) = 0, so the equation simplifies to c1(π/2) = 0. This implies that c1 = 0.
Since c1 = c2 = 0, the only solution to the equation c1x + c2cos(x) = 0 for all x in F(-∞, ∞) is the trivial solution. Therefore, the set of vectors {x, cos(x)} is linearly independent.

how to know if a function has a vertical asymptote
To determine if a function has a vertical asymptote, you need to consider its behavior as the input approaches certain values.
A vertical asymptote occurs when the function approaches positive or negative infinity as the input approaches a specific value. Here's how you can determine if a function has a vertical asymptote:
Check for restrictions in the domain: Look for values of the input variable where the function is undefined or has a division by zero. These can indicate potential vertical asymptotes.
Evaluate the limit as the input approaches the suspected values: Calculate the limit of the function as the input approaches the suspected values from both sides (approaching from the left and right). If the limit approaches positive or negative infinity, a vertical asymptote exists at that value.
For example, if a rational function has a denominator that becomes zero at a certain value, such as x = 2, evaluate the limits of the function as x approaches 2 from the left and right. If the limits are positive or negative infinity, then there is a vertical asymptote at x = 2.
In summary, to determine if a function has a vertical asymptote, check for restrictions in the domain and evaluate the limits as the input approaches suspected values. If the limits approach positive or negative infinity, there is a vertical asymptote at that value.

Decide whether the following statement is compound if lana wins the election then mary will smile
The correct answer is OD. Although the word "then" appears in the statement, it is not used as a logical connective. So the statement is not compound.
The statement "If Laura sells her quota, then Marie will be happy" is a single declarative sentence. It consists of a conditional clause ("If Laura sells her quota") and a consequent clause ("then Marie will be happy"). However, these two clauses are not independent statements that can stand alone. Instead, they are connected in a cause-and-effect relationship. The word "then" in this context is not functioning as a logical connective, but rather as an indicator of the consequent clause.
A compound statement is formed by combining two or more independent statements using logical connectives such as "and," "or," or "if...then." In the given statement, there is no logical connective joining two independent statements.
Therefore, the statement is not compound.

can two different pairs of numbers have the same geometric mean? if so, give an example. if not, explain why not.
Yes, it is possible for two different pairs of numbers to have the same geometric mean. It is the nth root of the product of the numbers.
The geometric mean of a set of numbers is the nth root of the product of the numbers, where n is the total number of values in the set. The geometric mean is a measure of central tendency that is useful for calculating the average growth rate, finding a common ratio, or comparing values that are exponentially related.
To illustrate that two different pairs of numbers can have the same geometric mean, let's consider the following examples:
Pair 1: 2 and 8
Pair 2: 4 and 4
For Pair 1, the geometric mean is √(2 * 8) = √16 = 4.
For Pair 2, the geometric mean is √(4 * 4) = √16 = 4.
As we can see, both pairs have the same geometric mean of 4, even though the individual numbers in each pair are different. This shows that different pairs of numbers can have the same geometric mean. However, it is important to note that in general, there are infinitely many pairs of numbers that can have the same geometric mean.

The graph of the function f(x)=log5(x) is stretched vertically by a factor of 2, shifted to the left by 6 units, and shifted up by 4 units.
The transformed function would be g(x) = 2log5(x + 6) + 4. The vertical stretch by a factor of 2 indicates that the y-values of the original function are multiplied by 2, which makes the curve steeper. The horizontal shift to the left by 6 units means that the x-values of the original function are decreased by 6, and the curve is moved to the left.
The upward shift by 4 units means that the entire graph of the transformed function is raised 4 units vertically, and the curve is shifted upwards.
To graph the transformed function, we can first plot some points of the original function f(x)=log5(x), then apply the transformations. For example, when x=1, f(x)=0, and when x=5, f(x)=1. We can then shift the points left by 6 units and multiply the y-values by 2, and shift the graph up by 4 units. This would give us the corresponding points of the transformed function g(x) = 2log5(x + 6) + 4. By connecting the transformed points, we can graph the transformed function.

8 - 4a = -2a
7th Grade Linear Questions
Answer:
a = 4
Step-by-step explanation:
So your goal here is to get the variable on just one side, so add 4a to both sides. This cancels out the 4a on of of the sides and puts a on the other side. The new equation is 8 = -2a + 4a. Combine like terms to get 8 = 2a. Divide both sides by 2 to get a = 4. You can check your work by replacing a with 4:
8 - 4(4) = -2(4)
8 - 16 = -8
-8 = -8
Since the final result is true, (-8 does equal -8,) a = 4.
lines a and b are a graph of a system of equations line a passes through the points (0,4) and (8,6) line b passes through the points (0,-2) and (8,1) do the intersect
The graph of line a and line b is shown in the image attached below. The lines do not intersect each other.
How to Graph a System of Equations?To check if both lines intersect, we need to graph the system of equations. First, use the points given to write out the equations.
Line a:
Slope (m) = change in y / change in x = 6 - 4 / 8 - 0 = 2/8
m = 1/4
Find the y-intercept (b) by substituting m = 1/4, x = 0 and y = 4 into y = mx + b:
4 = 1/4(0) + b
b = 4
The equation of line a is: y = 1/4x + 4.
Line b:
Slope (m) = change in y / change in x = 1 - (-2) / 8 - 0
m = 3/8
Find the y-intercept (b) by substituting m = 3/8, x = 0 and y = -2 into y = mx + b:
-2 = 3/8(0) + b
b = -2
The equation of line b is: y = 3/8x - 2.

Which of these statements is true? Sin 18° = cos 72°, sin 55° = cos 55°, sing 72° = cos 18°c both a and c
Answer:
Sin 18° = cos 72° and sin 72° = cos 18°
Step-by-step explanation:
According to trigonometry identity;
sin Ф = cos(90 - Ф)
for Sin 18° = cos 72
Ф = 18°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 18 = cos(90 - 18)
Sin 18 = cos 72
Hence the statement id true
For sin 72° = cos 18
Ф = 72°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 72 = cos(90 - 72)
Sin 72 = cos 18
Hence this statement too is correct
The two correct statements are Sin 18° = cos 72° and sin 72° = cos 18°

A train traveled 1/4 of the distance between two cities in 2/3 of an hour. at this rate, what fraction of the distance can the train travel in one hour
====================================================
Explanation:
A = fraction of the distance traveled in 2/3 of an hourB = time value that pairs up with AC = fraction of the distance traveled in 1 hourD = time value that pairs with CIn this case,
A = 1/4B = 2/3C = unknownD = 1We can set up the proportion
A/B = C/D
Which cross multiplies to
A*D = B*C
Let's plug in the known values and solve for C
A*D = B*C
(1/4)*(1) = (2/3)*C
1/4 = (2/3)*C
(2/3)*C = 1/4
3*(2/3)*C = 3*(1/4) ..... multiply both sides by 3
2C = 3/4
(1/2)*2C = (1/2)*(3/4) .... multiply both sides by 1/2
C = (1*3)/(2*4)
C = 3/8
The train travels 3/8 of the distance in 1 hour.

(C) c varies directly as a and inversely as b. If c= 15 when a = 18 and b = 40, find c when a = 36, and b = 25. = с
Answer:
c = 48
Step-by-step explanation:
Given c varies directly as a and inversely as b then the equation relating them is
c = \(\frac{ka}{b}\) ← k is the constant of variation
To find k use the condition c = 15 when a = 18 and b = 40 , then
15 = \(\frac{18k}{40}\) ( multiply both sides by 40 )
600 = 18k ( divide both sides by 18 )
\(\frac{600}{18}\) = k
\(\frac{100}{3}\) = k
c = \(\frac{100a}{3b}\) ← equation of variation
When a = 36 and b = 25 , then
c = \(\frac{100(36)}{3(25)}\) = \(\frac{3600}{75}\) = 48
