Lee wants to make at least $400 profit from selling t-shirts. The initial start up costs for making t-shirts is $125. Write an inequality that represents the amount of sales, s, that Lee must have to reach the goal.
The inequality that represents the amount of sales, \(s$,\) that Lee must have to reach the goal is:
\($$s \geq \frac{525}{p}$$\)
What is profit ?In business and finance, profit refers to the monetary gain earned by a business or individual after subtracting the expenses from the total revenue. In other words, profit is the difference between the amount of money earned from selling goods or services and the total cost of producing or delivering those goods or services. Profit is often used as a key performance indicator (KPI) to measure the financial success of a business or individual.
According to given information ?Let's assume that the cost of making one t-shirt is c and Lee sells each t-shirt for p.
To make at least $400 profit, Lee's revenue from sales p must be greater than or equal to the sum of the startup costs $125 and the desired profit $400:
\($$p\times s \geq 125+400$$\)
We can simplify this inequality to:
\($$p\times s \geq 525$$\)
Therefore, the inequality that represents the amount of sales, \(s$,\) that Lee must have to reach the goal is:
\($$s \geq \frac{525}{p}$$\)

do all square numbers have an odd number of factors
No, not all square numbers have an odd number of factors. In fact, square numbers can have either an odd or an even number of factors, depending on their prime factorization.
A square number is a number that can be expressed as the product of an integer multiplied by itself. For example, 4 is a square number because it can be written as 2 * 2.
When we analyze the factors of a square number, we find that each factor has a corresponding pair that multiplies to give the square number. For instance, the factors of 4 are 1, 2, and 4. We can see that the pairs are (1, 4) and (2, 2). Thus, 4 has an even number of factors.
However, there are square numbers that have an odd number of factors. Consider the square number 9, which is equal to 3 * 3. The factors of 9 are 1, 3, and 9. In this case, 9 has an odd number of factors.
In conclusion, while some square numbers have an odd number of factors (like 9), others have an even number of factors (like 4). The determining factor is the prime factorization of the square number.

a helpful rule for converting radians to degrees is
Answer:
Degrees = Radians x 180/π
or
Degrees = 57.2958 x radians
Step-by-step explanation:
1 radian = 180/π degrees
1 radian = 57.2958 degrees
Multiply radians by this factor of 57.2958 to get the equivalent measure in degrees
π radians = 180°
2π radians = 360° which is the number of degrees in a circle
For anything greater than 2π radians you will have to subtract 360°
For example, 7 radians using the formula is 7 x (57.2958 ) ≈ 401.07°
But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

find the largest positive integer $n$ such that for all real numbers $a 1,$ $a 2,$ $\dots,$ $a {n 1},$ where $a {n 1} \neq 0,$ the equation \[a {n 1} x^2 - 2x \sqrt{a 1^2 a 2^2 \dots a {n 1}^2} (a 1 a 2 \dots a n)
The largest positive integer $n$ for which the given equation holds true for all real numbers $a_1, a_2, \dots, a_{n-1}$ (where $a_{n-1} \neq 0$) is $n = 3$.
We are given the equation $a_{n-1}x^2 - 2x\sqrt{a_1^2a_2^2\dots a_{n-1}^2}(a_1a_2\dots a_{n-1}) = 0$, and we want to determine the largest $n$ for which this equation holds true for any choice of $a_1, a_2, \dots, a_{n-1}$.
If we simplify the equation, we can rewrite it as $x^2 - 2x\left|a_1a_2\dots a_{n-1}\right| = 0$. From this equation, we can observe for any non-zero value of $a_1a_2\dots a_{n-1}$, the equation will always hold true, regardless of the value of $x$. However, when $a_1a_2\dots a_{n-1} = 0$, the equation becomes $x^2 = 0$, which implies that $x = 0$.
Therefore, for $n > 3$, we can find values of $a_1, a_2, \dots, a_{n-1}$ for which the equation does not hold true, making $n = 3$ the largest positive integer for which the equation holds true for all $a_1, a_2, \dots, a_{n-1}$.

66
Answer:
m<6=66°
Step-by-step explanation:
Because m<2 and m<3 are both on a straight line, we know they must add to 180°:
m<2 + m<3 =180
We know m<3=114°, so:
m<2 +114 = 180
m<2 = 66
Since AB|CD, m<2 and m<6 are corresponding angels, making them equal, and so m<6=66°.

an isosceles triangle has two sides of length 40 and a base of length 48. a circle circumscribes the triangle. what is the radius of the circles?a. 20sqrt(2)b. 28c. 18sqrt(3)d. 12sqrt(5)e. 25
The radius of the circle circumscribing the isosceles triangle is :
(a) 20sqrt(2).
To find the radius of the circle circumscribing the isosceles triangle, we need to use the fact that the perpendicular bisectors of the sides of the triangle intersect at the center of the circle. Since the triangle is isosceles, the perpendicular bisector of the base will also be an altitude, so it will intersect the base at its midpoint. Let's call this point M.
First, we can use the Pythagorean theorem to find the height of the triangle. If we draw an altitude from the vertex opposite the base to the midpoint of the base, we get two right triangles that are congruent by the hypotenuse-leg congruence theorem. Let's call the height h. Then:
h^2 + 24^2 = 40^2
h^2 = 40^2 - 24^2
h = sqrt(40^2 - 24^2)
h = 32
Now we can find the distance from the center of the circle to point M, which is the radius of the circle. Let's call this distance r. Since M is the midpoint of the base, its distance from each endpoint is 24. We can use the Pythagorean theorem again to find r:
r^2 = h^2 + 24^2
r^2 = 32^2 + 24^2
r^2 = 1152
r = sqrt(1152)
r = 12sqrt(8)
r = 24sqrt(2)
So the answer is (a) 20sqrt(2).

Solving linear homogeneous recurrence relations with variable coefficients can be challenging, especially when there are no clear patterns to follow. However, there are methods that can help make the process more systematic. One approach is to use the characteristic equation, which involves finding the roots of the polynomial equation that represents the recurrence relation.

\( \: {i}^{31} = \)
q2:
\( \sqrt{ - 20} \times \sqrt{ - 12} = \)
q3:
\( 3i \times 4i = \)
Since i = √(-1), it follows that i ² = -1, i ³ = -i, and i ⁴ = 1.
q1. We have
i ³¹ = i ²⁸ × i ³ = (i ⁴)⁷ × i ³ = 1⁷ × (-i ) = -i
q2. Approach each square root individually:
√(-20) = √(-1 × 2² × 5) = √(-1) × √(2²) × √5 = 2i √5
√(-12) = √(-1 × 2² × 3) = √(-1) × √(2²) × √3 = 2i √3
Then
√(-20) × √(-12) = (2i √5) × (2i √3) = (2i )² √(5 × 3) = -4√15
You may have been tempted to combine the square roots immediately, but that would have given the wrong answer.
√(-20) × √(-12) ≠ √((-20) × (-12)) = √240 = 4√15
More generally, we have
√a × √b ≠ √(a × b)
for complex numbers a and b. Otherwise, we would have nonsensical claims like 1 = -1 :
√(-1) × √(-1) = i ² = -1
whereas

q3. Nothing tricky about this one:

You have a balance of 17,426 on your credit card. Your minimum monthly payment is 461 . If your interest rate is 15.5%, how many years will it take to pay off your card assuming you don't add any debt? Enter your response to two decimal places (ex: 1.23)
With a credit card balance of $17,426, a minimum monthly payment of $461, and an interest rate of 15.5%, we need to calculate the number of years it will take to pay off the card without adding any additional debt.
To determine the time required to pay off the credit card, we consider the monthly payment and the interest rate. Each month, a portion of the payment goes towards reducing the balance, while the remaining balance accrues interest.
To calculate the time needed for repayment, we track the decreasing balance each month. First, we determine the interest accrued on the remaining balance by multiplying it by the monthly interest rate (15.5% divided by 12).
We continue making monthly payments until the remaining balance reaches zero. By dividing the initial balance by the monthly payment minus the portion allocated to interest, we obtain the number of months needed for repayment. Finally, we divide the result by 12 to convert it into years.
In this scenario, it will take approximately 3.81 years to pay off the credit card (17,426 / (461 - (17,426 * (15.5% / 12))) / 12).
