The the simplified form of the given expression 12.5 - 31/2 + 1 1/4 is -7/4.

Hence, option D) -7/4 is the correct answer.

Given the expression in the question;

12.5 - 31/2 + 1 1/4

First, convert the mixed fraction into an improper fraction.

1 1/4 = ( 1×4 + 1 )/4 = ( 4 + 1 )/4 = 5/4

Now, rewrite the expression as;

12.5 - 31/2 + 5/4

Find the common denominator

( 12.5/1 × 4/4 ) - ( 31/2 × 2/2 ) + ( 5/4 × 1/1 )

( 12.5/1 × 4/4 ) - ( 31/2 × 2/2 ) + ( 5/4 × 1/1 )

Perform the multiplication operation

50/4 - 62/4 + 5/4

Now, combine the numerators over the common denominator.

( 50 - 62 + 5 )/4

( -12 + 5 )/4

( -7 )/4

-7/4

The the simplified form of the given expression 12.5 - 31/2 + 1 1/4 is -7/4.

Hence, option D) -7/4 is the correct answer.

A Venn diagram uses overlapping circles and other shapes to show logical relationships between two or more groups of elements. It often helps to organize things graphically by highlighting similarities and differences between elements.

Venn diagrams, also known as set diagrams or logic diagrams, are widely used in mathematics, statistics, logic, education, linguistics, computer science, and economics. Venn diagrams became part of his "new mathematics" curriculum in the 1960s, so many people encounter them for the first time when learning mathematics or logic in school. These can be simple diagrams spanning 2 or 3 sets of a few items, or can be very sophisticated including 3D presentations as you progress to 6 or 7 sets or more. There is also They are used to reason about and represent how objects are related to each other within a particular "universe" or segment. Venn diagrams are widely used in presentations and reports as they allow users to visualize data in a clear and powerful way. These are closely related to Euler diagrams, differing in that the set is omitted if it has no elements. Venn diagrams show relationships even when the set is empty.

Answer:

\(\frac{x}{2}\)

Step-by-step explanation:

the y-value is when the x-value is divided by 2

Is the relation a function: C. No, because for each input there is not exactly one output.

In Mathematics, a function is typically used for uniquely mapping an independent value (input variable or domain) to a dependent value (range or output variable).

This ultimately implies that, an independent value represents the value on the x-axis of a cartesian coordinate while a dependent value represents the value on the y-axis of a cartesian coordinate.

Since the independent value (12) is mapped to multiple dependent values (-4 and -2), we can logically deduce that the relation does not represent a function.

The given statement is True.

What is conditional statement?

A conditional statement is a type of logical statement that has two parts: a hypothesis and a conclusion. The hypothesis is the "if" part of the statement, and the conclusion is the "then" part. The conditional statement asserts that if the hypothesis is true, then the conclusion must also be true.

The given statement is True.

This is an example of a proof by conditional statement. To prove a conditional statement of the form "If A, then B," you assume A and use deductive reasoning to show that B logically follows. In this case, you assume the antecedent (c ⊃ (i ≡ z)) and attempt to prove the consequent (f) within the scope of that assumption. If you are successful, then you have shown that the conditional statement is true.

Therefore  $6,440 money will Grayson have to retire.

We must first determine the entire number of months Grayson will be saving for in order to determine how much money he would need to retire. Since there are 12 months in a year and he plans to retire in 20 years, he will be saving for 20 * 12 to equal 240. 30 years.

Next, we can figure out how much money Grayson will need to retire using the compound interest formula:

A = P(1 + r/n)^(nt)

Where:

A is the total amount Grayson will need to retire, and P represents the monthly saving goal ($1,000).

Since interest is compounded monthly, r represents the annual interest rate of nine percent and n represents the number of times interest is compounded annually.

The number of years Grayson will be setting up money is t. (20)

With these values entered into the formula, we obtain:

A = $1,000(1 + 0.09/12)^(12*20)

A = $1,000(1.0075)^(240) (240)

A = $1,000(6.44) (6.44)

A = $6,440

The Critical point and Point of Inflection for the function f(x) = a/(x² + b²) are (0, a/b²) and (b/√3, 3a/4b²) respectively.

The given function is,

f(x) = a/(x² + b²) = a(x² + b²)⁻¹

Differentiating the function with respect to 'x' we get,

f'(x) = -a(x² + b²)⁻²(2x) = -2ax(x² + b²)⁻²

f''(x) = 2a[-2x(x² + b²)⁻³(2x) + (x² + b²)⁻²] = 2a(x² + b²)⁻²[-4x² + (x² + b²)] = 2a(x² + b²)⁻²[ -3x² + b²]

Now, for critical point,

f'(x) = 0 gives

-2ax(x² + b²)⁻² = 0

x = 0

So, at x = 0, f(0) = a/b²

Hence, (0, a/b²) is the critical point.

For point of Inflection,

f''(x) = 0

2a(x² + b²)⁻²[ -3x² + b²] = 0

3x² = b²

x² = b²/3

x = b/√3

So at x = b/√3, f(b/√3) = 3a/4b²

Hence the point of inflection is (b/√3, 3a/4b²).

Answer:

Yes, x^2 + 2y = 4 is a function.

Step-by-step explanation:

x^2 + 2y = 4

Solve for y.

2y = -x^2 + 4

f(x) = -(1/2)x^2 + 2

Answer: Yes, x^2 + 2y = 4 is a function.

To find the length of the graph of f(x)=ln(4sec(x)) for 0≤x≤π/3, we first need to compute the derivative of the function.

f(x) = ln(4sec(x))
f'(x) = (1/sec(x)) * (4sec(x)) * tan(x) = 4tan(x)
Next, we use the arc length formula:
L = ∫ [a,b] √[1 + (f'(x))^2] dx
Substituting in the values, we get:
L = ∫ [0,π/3] √[1 + (4tan(x))^2] dx
We can simplify this by using the identity 1 + tan^2(x) = sec^2(x):
L = ∫ [0,π/3] √[1 + (4tan(x))^2] dx
 = ∫ [0,π/3] √[1 + 16tan^2(x)] dx
 = ∫ [0,π/3] √[sec^2(x) + 16] dx
 = ∫ [0,π/3] √[(1 + 15cos^2(x))] dx
 = ∫ [0,π/3] √15cos^2(x) + 1 dx
Using the substitution u = cos(x), we get:
L = ∫ [0,1] √(15u^2 + 1) du
This can be solved using trigonometric substitution, but the details are beyond the scope of this answer. The final result is:
L = 4/3 * √(15) * sinh^(-1)(√15/4) - √15/2
Therefore, the length of the graph of f(x)=ln(4sec(x)) for 0≤x≤π/3 is approximately 3.195 units.

For subspaces to be orthogonal, their intersection must be the zero vector.

Therefore, we can determine whether the subspaces are orthogonal by checking if the dot product between any two vectors, one from each subspace, is equal to zero.
For S_1 and S_2, the dot product between [4 5 -4] and [5 -4 0] is not equal to zero, so they are not orthogonal.
For S_1 and S_2, the dot product between [1 1 1 1] and [-1 1 -1 1] and [0 2 -2 0] is equal to zero, so they are orthogonal.
For S_1 and S_2, the dot product between [0 0 2 1] and [3 2 0 0] and [0 1 -2 2] is equal to zero, so they are orthogonal.
Two subspaces are orthogonal if their vectors have a dot product of zero. For S_1 = span {[4 5 -4], [0 1 1]} and S_2 = span {[5 -4 0]}, the dot products are (4)(5) + (5)(-4) + (-4)(0) = 0. They are orthogonal.
For S_1 = span {[1 1 1 1]} and S_2 = span {[-1 1 -1 1], [0 2 -2 0]}, the dot product of S_1 and both vectors in S_2 is non-zero. They are not orthogonal.
For S_1 = span {[0 0 2 1], [0 0 1 -2]} and S_2 = span {[3 2 0 0], [0 1 -2 2]}, the dot product of all pairs of vectors is zero. They are orthogonal.

The distance covered by the scooter during the 6-hour time period is 540 km.

A scooter travels along a straight line at a constant speed of 90 km/h for a time period of 6 hours. We need to calculate the distance covered by the scooter during this time.

To calculate the distance covered, we can use the formula:

Distance = Speed × Time

In this case, the speed is provided as 90 km/h, and the time is provided as 6 hours.

Plugging in these values into the formula, we get:

Distance = 90 km/h × 6 hours

The pet will need 3 tablets of Albon for the treatment. This can be answered by the concept of Simple mathematics.

To calculate the required dosage, we need to convert the pet's weight from pounds to kilograms, which gives us 11.36 kg. On day 1, the pet requires 5 mg/kg of Albon, which amounts to 56.8 mg. Since each tablet contains 125 mg, we need to give the pet 0.454 tablets (56.8/125) which we will round up to 1 tablet. For the next 5 days, the pet requires 2.5 mg/kg of Albon, which amounts to 28.4 mg.

Therefore, we will give the pet 0.227 tablets (28.4/125) which we will round up to 1/4 of a tablet (0.25 tablets) each day. So, over the course of 6 days, the total number of tablets needed will be 1 + (0.25 x 5) = 2.25, which we will round up to 3 tablets.

Therefore, the owner will need to be dispensed with 3 tablets of Albon for the pet's treatment.
