determine which number or numbers can be a solution for the inequality
32+a>44 11, 12, 13, 14
The numbers can be a solution for the inequality 32+a>44 is 13 and 14.
What is the solution set to an inequality or an equation?If the equation or inequality have variable terms, than there might be some values of those variables for which the equation or inequality might be correct. Such values are known as solution to that equation or inequality. To set of such values are called solution set to be considered equation or inequality.
Given that;
The inequality= 32+a>44
To solve the inequality 32 + a > 44, we need to isolate the variable "a" on one side of the inequality.
32 + a > 44
Subtract 32 from both sides:
a > 44 - 32
a > 12
This means that any number greater than 12 can be a solution to the inequality.
Therefore, the inequalities numbers 13 and 14 can be solutions, but 11 and 12 cannot.

find the domain and range of each f(x)^ * = 1 + x ^ 2
The function f(x)* = 1 + x^2 is defined for all real numbers x, so the domain is all real numbers, or (-∞, ∞).
How to explain the domainIn determining the function's output values, one must consider its collection of feasible results to extract the range. Reviewing f(x)* exhibits a minimum value of 1 due to x^2 being perpetually non-negative, while adding another factor merely preserves positivity.
Concurrently as x skyrockets, so too does the value of f(x)* given that approaching infinity generates infinitely larger powers than any constant coefficient subordinated by it. Consequently, the overall range of f(x)* becomes [1, ∞), enwrapping all feasible solutions equivalent or superior to 1.

Solve each of the following equations. Show its solution set on a number line. Check
your answers.
|3x-2| = 19
Answer:
\(x=7 \quad \text{or} \quad x=-\dfrac{17}{3}\)
Step-by-step explanation:
The absolute value of a number is its positive numerical value.
Given equation:
\(|3x-2| = 19\)
To solve an equation containing an absolute value, first isolate the absolute value on one side of the equation. (This has already been done).
Set the contents of the absolute value equal to both the positive and negative value of the number on the other side of the equation, and solve both equations:
\(\begin{aligned}\text{\underline{Equation 1}} &&\quad && \text{\underline{Equation 2}}\\3x-2 & = 19 && & 3x-2&=-19\\3x-2+2 & = 19+2 && & 3x-2+2&=-19+2\\3x&=21 &&& 3x&=-17\\\dfrac{3x}{3}&=\dfrac{21}{3} &&& \dfrac{3x}{3}&=-\dfrac{17}{3}\\x&=7 &&& x&=-\dfrac{17}{3}\end{aligned}\)
Check the solutions by substituting each found value of x into the original equation:
\(\begin{aligned}x=7 \implies |3(7)-2|&=19\\|21-2|&=19\\|19|&=19\\19&=19\end{aligned}\)
\(\begin{aligned}x=-\dfrac{17}{3} \implies \left|3\left(-\dfrac{17}{3}\right)-2\right|&=19\\|-17-2|&=19\\|-19|&=19\\19&=19\end{aligned}\)
Therefore, this verifies that both solutions are valid.

Place a closed circle at x = 7.Place a closed circle at x = -¹⁷/₃ = -5 ²/₃Televisions are on sale for 40% OFF the original price of $600. After tax (8.5%) is applied, what is the final price?
First, determine what is 40% of $600. Multiple 40 (as a decimal) by 600.
0.4 x 600 = 240
Therefore, the discount is $240 off $600.
Subtract the two values to find price (before tax): 600 - 240 = 360
So the TV will cost $360 before tax.
The tax is 8.5%. Multiply 8.5 as a decimal by 360 to find the amount of tax added.
0.085 x 360 = 30.6
Add 30.6 and the price before tax to find the final price.
30.6 + 360 = 390.60
Therefore, the final price of the TV is $390.60

The period p of a pendulum, or the time it takes for the pendulum to make one complete swing, varies directly as the √L, where Length of the pendulum. If the period of a pendulum is 1.1 s when the length is 2 ft, find the period when the length is 7 ft.
The length of the pendulum is 7 ft, the period is approximately 1.86 seconds.
The problem states that the period of a pendulum varies directly as the square root of its length. This means that as the length of the pendulum increases, so does its period. In mathematical terms, we can express this relationship as:
p ∝ √L
where p is the period of the pendulum and L is its length. The symbol "∝" means "is proportional to."
To find the period of a pendulum when its length is 7 ft, we can use the given information that the period is 1.1 s when the length is 2 ft. We can set up a proportion using the formula above:
p₁/√L1 = p₂/√L2
where p₁ = 1.1 s, L1 = 2 ft, p₂ = the unknown period we want to find, and L2 = 7 ft.
Plugging in the values we know, we get:
1.1/√2 = p₂/√7
To solve for p₂, we can cross-multiply and simplify:
1.1 x √7 = p₂ x √2
p₂ = (1.1 x √7) / √2
p₂ ≈ 1.86 s

How will the product change if one number is increased by a factor of 12 and the other is decreased by a factor of 4
If one number is increased by a factor of 12 and the other is decreased by a factor of 4, the product of the two numbers will be multiplied by a factor of 3.
Let's suppose we have two numbers, A and B, and we want to know how their product will change if one number is increased by a factor of 12 and the other is decreased by a factor of 4.
The initial product of the two numbers is:
A x B
If we increase A by a factor of 12, the new value of A will be 12A. If we decrease B by a factor of 4, the new value of B will be B/4. Therefore, the new product of the two numbers will be:
(12A) x (B/4) = (12/4) x A x B = 3AB
So the new product of the two numbers will be three times the initial product. In other words, if one number is increased by a factor of 12 and the other is decreased by a factor of 4, the product of the two numbers will increase by a factor of 3.

The length of the base of the triangle is 8 yards whose height is half of 28 yards.
What is triangle?A triangle is a two-dimensional geometric shape that is formed by three straight lines that connect three non-collinear points. These three lines are called the sides of the triangle, and the points where the sides meet are called the vertices of the triangle.
According to question:The following formula provides the area of a triangle:
Area = (1/2) x base x height
We are given that the height of the triangle is half of 28 yards, which is:
height = 1/2 x 28 = 14 yards
We are also given that the area of the triangle is 56 square yards. Substituting these values into the formula for the area, we get:
56 = (1/2) x base x 14
Simplifying this equation, we get:
56 = 7 x base
Dividing both sides by 7, we get:
base = 8
Therefore, the length of the base of the triangle is 8 yards.

3. An investor plans to invest $500/year and expects to get a 10.5% return. If the investor makes these contributions at the end of the next 20 years, what is the present value (PV) of this investment today?
The present value (PV) of the investment today is approximately $2,965.05.
To find the present value (PV) of the investment today, we need to calculate the present value of each individual contribution and then sum them up. We can use the formula for the present value of an annuity to do this calculation.
The formula for the present value of an annuity is given by:
PV = C * [(1 - (1 + r)^(-n)) / r]
Where:
PV = Present Value
C = Cash flow per period
r = Interest rate per period
n = Number of periods
In this case, the cash flow per period (C) is $500, the interest rate per period (r) is 10.5% (or 0.105), and the number of periods (n) is 20 years.
Let's plug in these values into the formula and calculate the present value (PV):
PV = $500 * [(1 - (1 + 0.105)^(-20)) / 0.105]
Using a calculator, we can evaluate the expression inside the brackets:
PV = $500 * [(1 - 0.376889) / 0.105]
Simplifying further:
PV = $500 * [0.623111 / 0.105]
PV = $500 * 5.930105
PV = $2,965.05
Therefore, the present value (PV) of the investment today is approximately $2,965.05.

Step-by-step explanation:
How do I find the possible degree(s) of a function from the graph alone?
Answer:
To determine the possible degree(s) of a function from the graph alone, you need to examine the behavior of the graph at the extremes (far left and far right) and consider the number of turning points or changes in direction. Here's a step-by-step approach:
Look at the far left side of the graph: Determine the behavior of the graph as it approaches negative infinity. Does the graph approach a specific value, such as a horizontal line (asymptote) or the x-axis? If the graph approaches a horizontal line, it suggests a polynomial function of even degree. If the graph approaches the x-axis, it indicates a polynomial function of odd degree or possibly a function with a root of multiplicity greater than one.
Look at the far right side of the graph: Determine the behavior of the graph as it approaches positive infinity. Similar to step 1, observe if the graph approaches a specific value or a horizontal line. The behavior at the far right side should be consistent with the behavior at the far left side. This can help you identify if the function is even or odd degree.
Examine the number of turning points or changes in direction: Count the number of times the graph changes direction. These points are where the slope of the graph changes from positive to negative or vice versa. The number of turning points can provide an indication of the degree of the polynomial. For example, if there are two turning points, it suggests a polynomial function of degree 3.
Remember that this method provides potential degrees, but it may not definitively determine the exact degree of the function. Additional information or analysis might be required for a more accurate determination.

Multiplying the determinant of the 2x2 matrix by 2, we get:
4(-x - 3) - (-6)(2) = 0
Simplifying the left-hand side, we get:
-4x - 12 + 12 = 0
Solving for x, we get:
-4x = 0
x = 0
Therefore, X must be equal to 0 for M to be singular.
