Sal will pay to tile his entryway by calculating the area of the entryway in square feet and multiplying it by the cost of the tile per square foot.
To determine the cost of tiling Sal's entryway, we need to calculate the area of the floor plan. Since each unit length represents 1 foot, we can consider the dimensions of the floor plan in terms of feet. Let's say the length is 'L' feet and the width is 'W' feet. The area can be found by multiplying L by W, giving us the total area in square feet.
Once we have the area, we can multiply it by the cost per square foot, which is $1.15. This will give us the total cost of the tiles needed to cover the entryway.
It's important to note that rounding the final answer to the nearest cent is necessary to provide a precise cost value.
Therefore, by calculating the area of the entryway and multiplying it by the cost per square foot, we can determine the total amount Sal will pay to tile his entryway.
In conclusion, to calculate the cost, we need to find the area of the entryway by multiplying the length and width in units, convert it to square feet, and then multiply it by the tile cost per square foot.

A pair of gamma rays emitted from the same annihilation event collide with sensors, but their collisions occur 0.33 nanoseconds apart. What is the minimum distance the annihilation could have occurred from the center of the machine
The minimum distance the annihilation event could have occurred from the center of the machine is approximately 98.94 nanometers.
To determine the minimum distance the annihilation event could have occurred from the center of the machine, we can use the speed of light as a constant and the time difference between the collisions of the gamma rays.
The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).
Since the time difference between the collisions of the gamma rays is given as 0.33 nanoseconds, we need to convert this time to seconds. One nanosecond is equal to 1 × 10⁻⁹seconds.
0.33 nanoseconds is equal to 0.33 × 10⁻⁹ seconds.
Now, we can calculate the minimum distance using the equation:
Distance = Speed of light × Time
Distance = 299,792,458 m/s × 0.33 × 10⁻⁹ seconds
Distance ≈ 98.94 nanometers

en una tienda de ropa, la semana pasada, 3 pantalones y 2 abrigos costaban 245€. Esta semana estos artículos tienen un descuento del 20% y 5% respectivamente. Si ahora un pantalón y un abrigo cuestan 100,75€, ¿qué costaba cada artículo antes de la rebaja?
Solving a system of equations we can see that each pair of pants costs €82.94 and each coat costs €26.37
How to find the original cost?
Let's define the variables:
x = cost of a pant
y = cost of a coat.
First, we know that:
3x + 2y = 245
And then there are discounts of 20% and 5%, and the cost of one of each is 100.75, then:
0.8x + 0.95y = 100.75
Then we have a system of equations:
3x + 2y = 245
0.8x + 0.95y = 100.75
We can isolate x on the second equation to get:
x = (100.75 - 0.96y)/0.8
x = 125.9 - 1.2y
Replace that in the other equation:
3*(125.9 - 1.2y) + 2y = 245
Solving for y:
3*125.9 - 3*1.2y + 2y = 245
y*(2 - 3*1.2) = 245 - 3*125.9
y = (245 - 3*125.9)/(2 - 3*1.2)
y = 82.94
Then the value of x is:
x = 125.9 - 1.2*82.94
x = 26.37

At any time t > 0,the rate at which a person can memorize a list of M words is proportional to the product of the number of words memorized ad tlie number of words tlat have not been memorized. If 2 denotes the number of words memorized at time t, which differential equation models this situation? Assume kis a positive constant; A. d k dt B. d k ( - M) dt C d k(M - 2) dt D. d =Rt(M -t) dt
The differential equation that models this situation is dx/dt = kx(M - x) (option c).
To determine the differential equation that models the situation, let's analyze the problem statement.
The rate at which a person can memorize a list of M words is proportional to the product of the number of words memorized and the number of words that have not been memorized.
Let's denote the number of words memorized as "a" and the number of words not yet memorized as "M - a" (where M is the total number of words in the list).
The problem states that the rate of memorization is proportional to the product of "a" and "M - a". We can express this mathematically as:
Rate of memorization ∝ a * (M - a)
To convert this proportionality into an equation, we introduce a positive constant k:
Rate of memorization = k * a * (M - a)
The left side of the equation represents the rate of change of the number of words memorized (da/dt), and the right side represents the product of "a" and "M - a" multiplied by the constant k.
Therefore, the differential equation that models this situation is:
da/dt = k * a * (M - a)
Comparing this with the given options, we can see that the correct choice is option C:
dx/dt = k * x * (M - x)
The complete question is:
At any time t > 0 the rate at which a person can memorize a list of M words is proportional to the product of the number of words memorized and the number of words that have not been memorized. If a denotes the number of words memorized at time t, which differential equation models this situation? Assume k is a positive constant.

She plans on washing cars for $25 per car.
Ereed wash c cars to have enough to purchase the bicycle.
Select the 3 orrect equations below that can be used to represent when she will be able to purchase the bicycle she wants
The correct equations which can be used to represent when she will be able to purchase the bicycle she wants are:
250 = 125+25c125 = 25cc = 5Given, Eva wants to buy a bicycle.
The cost of bicycle is = $250
Saving's of Eva = $125
Eva plans on washing cars for $25 per car.
Eva wash 'c' cars to have enough to purchase the bicycle.
cost of bicycle = saving's of Eva + Eva washing 'c' cars for $25 per car.
⇒ 250 = 125 + 25c
arrange the like terms on one side.
⇒ 250 - 125 = 25c
⇒ 125 = 25c
⇒ 25c = 125
⇒ c = 125/25
⇒ c = 5
hence Eva washes 5 cars to earn $125 which gets added to the savings and becomes the cost of the bicycle she wants to purchase.
⇒ cost of bicycle = 125+25(5)
⇒ cost of bicycle = 125+125
⇒ cost of bicycle = $250

ind the values of the trigonometric functions of t from the given information. csc(t) = 7, cos(t) < 0
So, the values of the trigonometric functions of t are sin(t) = 1/7, cos(t) = -√(1 - (1/7)^2) and tan(t) = -(1/7)/(-√(1 - (1/7)^2)).
Given that csc(t) = 7 and cos(t) < 0, we can find the values of the other trigonometric functions of t using the relationships between the trigonometric functions.
csc(t) = 1/sin(t), so sin(t) = 1/7
Since cos(t) < 0, t is in the second or third quadrant, where sin(t) is positive. Hence, t is in the third quadrant.
Therefore, the values of the trigonometric functions of t are:
sin(t) = 1/7
cos(t) = -√(1 - sin^2(t)) = -√(1 - (1/7)^2)
tan(t) = sin(t)/cos(t) = -(1/7)/(-√(1 - (1/7)^2))
Note that the values of the other trigonometric functions, such as cot(t), sec(t), and csc(t), can be found using the definitions of these functions and the values of sin(t) and cos(t) that we have found.

So, the values of the trigonometric functions of t are \(Sin(t)=\frac{1}{7}\), \(Cos(t)=-\sqrt{[1-(\frac{1}{7})^2] }\) and \(tan(t)=\frac{\frac{1}{7} }{-\sqrt{1-(\frac{1}{7})^2 } }\).
Given that csc(t) = 7 and cos(t) < 0, we can find the values of the other trigonometric functions of t using the relationships between the trigonometric functions.
\(Cosec(t)=7\)
We known
⇒ \(Sin(t)=\frac{1}{Cosec(t)} =\frac{1}{7}\)
Since cos(t) < 0, t is in the second or third quadrant, where sin(t) is positive. Hence, t is in the second quadrant.
Therefore, the values of the trigonometric functions of t are:
⇒ \(Sin(t)=\frac{1}{7}\)
⇒ \(Cos(t)=-\sqrt{[1-(Sin^2t)]}\)
⇒ \(Cos(t)=-\sqrt{[1-(\frac{1}{7})^2] }\)
⇒ \(tan(t)=\frac{Sin(t)}{Cos(t)}\)
⇒ \(tan(t)=\frac{\frac{1}{7} }{-\sqrt{1-(\frac{1}{7})^2 } }\)
∴ Note that The definitions of the other trigonometric functions, along with the values of Sin(t) and Cos(t), can be used to determine the values of cot(t), Sec(t), and Cosec(t).

Find the first and second derivatives. 5 y = - 4x® - 9 11
We are given a function y = -4x^3 - 9x^11, and we need to find its first and second derivatives.
To find the first derivative, we apply the power rule and the constant multiple rule. The power rule states that the derivative of x^n is nx^(n-1), and the constant multiple rule states that the derivative of kf(x) is k*f'(x), where k is a constant. Applying these rules, we can find the first derivative of y = -4x^3 - 9x^11.
Taking the derivative term by term, the first derivative of -4x^3 is -43x^(3-1) = -12x^2, and the first derivative of -9x^11 is -911x^(11-1) = -99x^10. So, the first derivative of y is dy/dx = -12x^2 - 99x^10.
To find the second derivative, we apply the same rules to the first derivative. Taking the derivative of -12x^2, we get -122x^(2-1) = -24x, and the derivative of -99x^10 is -9910x^(10-1) = -990x^9. Therefore, the second derivative of y is d^2y/dx^2 = -24x - 990x^9.

If we want to prove that x is equal to seven, we should first solve the equation for x so:
2x + 8 = 5x - 13
We should first add 13 on both sides and subtract 2x from both sides:
2x + 8 + 13 - 2x = 5x - 13 + 13 - 2x
