Answer:
113.4=x(18)
x=6.3
Step-by-step explanation:
It says the product of a number, x, and 18 is 113.4. Since it says product there will be multiplication. The word "is" tells us that x and 18 equals 113.4. Is x= 6.3, 6.3 times 18 equals 113.4. This is a true equation.

Solve your equation for Y(s). Y(s) = L{y(t)} = (58^3+2s^2+48)/(s^2(s^2+16)) c. Take the inverse Laplace transform of both sides of the previous equation to solve for y(t).
Answers
a. To solve the initial value problem using Laplace transforms, we start by taking the Laplace transform of both sides of the given differential equation. The Laplace transform of y(t) is denoted as Y(s). The Laplace transform of the second derivative y"(t) can be expressed as s²Y(s) - sy(0) - y'(0), where y(0) and y'(0) are the initial conditions. The Laplace transform of 48t is simply 48/s².
Applying the Laplace transform to the given differential equation, we get:
s²Y(s) - sy(0) - y'(0) + 16Y(s) = 48/s²
Substituting the initial conditions y(0) = 5 and y'(0) = 2, we have:
s²Y(s) - s(5) - 2 + 16Y(s) = 48/s²
Simplifying this equation gives the corresponding algebraic equation in terms of Y(s).
b. Now, we solve the equation obtained in part (a) for Y(s). Rearranging the terms, we have:
(s² + 16)Y(s) = 48/s² + s(5) + 2
Combining like terms, we get:
(s² + 16)Y(s) = (48 + 5s² + 2s) / s²
Dividing both sides by (s² + 16), we obtain:
Y(s) = (48 + 5s² + 2s) / (s²(s² + 16))
So, Y(s) is equal to the Laplace transform of y(t).
c. To find y(t), we take the inverse Laplace transform of Y(s) obtained in part (b). We can use partial fraction decomposition and the properties of Laplace transforms to simplify the expression and find the inverse Laplace transform.
Taking the inverse Laplace transform of Y(s), we find:
y(t) = L^(-1){Y(s)} = L^(-1){(48 + 5s² + 2s) / (s²(s² + 16))}
The inverse Laplace transform can be calculated using tables or software, and it yields the solution y(t) to the initial value problem.

Suppose a conic section passes through the point (2, - 7). If the conic section has focus ( - 1, -3), directrix 2 = 3, then it is a ellipse parabola hyperbola cannot be determined.
Answers
The conic section has focus ( - 1, -3), directrix 2 = 3, then it is a parabola.
How to find if the conic section is a ellipse parabola hyperbola?For a parabola, the focus and directrix play important roles in determining its shape. The distance between a point on the parabola and the focus is equal to the perpendicular distance between that point and the directrix.
Let's calculate the distances and verify if they are equal:
Distance between the point (2, -7) and the focus (-1, -3):
d₁ = √[(2 - (-1))² + (-7 - (-3))²] = √[9 + 16] = √25 = 5
Distance between the point (2, -7) and the directrix 2 = 3:
d₂ = |y - directrix| = |(-7) - 3| = |-10| = 10
Since d₁ ≠ d₂, we can conclude that the conic section cannot be an ellipse.
In an ellipse, the sum of the distances from any point on the ellipse to the two foci is constant. However, in this case, the distances are not equal.
Similarly, for a hyperbola, the difference between the distances from any point on the hyperbola to the two foci is constant. Since the distances are not equal in this case, we can also rule out a hyperbola.
Therefore, based on the given information, the conic section is a parabola.

Answers
Answer: Height of tree = 26 ft
Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.
Base = AC = 31
Perpendicular = CB = ?
Hypotenuse = AB
Using trigonometric equation
tan 40 (deg) = CB / AC
CB = Tan 40 x AC

You arder eighteen borritos to go from a Mexican restaurant, nine with hot peppers and nine without. However, the restaurant forget to be them. If you ve buite stranicom, find the probability of the given event
Answers
Answer : The probability of the given event occurring would be 0.75 or 75%.
Explanation :The given problem states that you ordered eighteen burritos, with nine having hot peppers and nine not having hot peppers. However, the restaurant forgot your order. We are supposed to find the probability of the event happening.
Let the probability of getting a burrito with hot peppers be P(h) and the probability of getting a burrito without hot peppers be P(n).
The total number of burritos ordered is 18.
Thus, P(h) + P(n) = 18. We can assume that all burritos are the same.
Thus, P(h) = 9/18 = 0.5 and P(n) = 9/18 = 0.5.
Therefore, the probability of getting an order that is incorrect would be: 1 - (0.5 * 0.5) = 1 - 0.25 = 0.75 or 75%. Therefore, the probability of the given event occurring would be 0.75 or 75%.

let θ be an angle in quadrant iii such that = cos θ − 4 5 . find the exact values of csc θ and tan θ
Answers
Let θ be an angle in quadrant iii such that = cosθ − 45, the exact values of csc θ and tan θ are 5/3 and -3/4 respectively.
As an angle θ is in quadrant III, and cosθ = -4/5
To identify the exact value of cscθ and tanθ, we will first calculate the value of sinθ by using the Pythagorean identity
sin²θ + cos²θ = 1
⇒ sin²θ + (-4/5)² = 1
⇒ sin²θ = 1 - (-4/5)² = 1 - 16/25 = 9/25
⇒ sinθ = √(9/25) = 3/5
Now, we can calculate the value of cscθ as
cscθ = 1/sinθ = 1/(3/5) = 5/3
Next, we can estimate the value of tanθ by using the identity
tanθ = sinθ/cosθ= (3/5) / (-4/5) = -3/4
Therefore, the exact values of cscθ and tanθ are
cscθ = 5/3 and tanθ = -3/4.

there are 12 socks in flora drawer 9 are red and 2 are blue and 1 is green she take out one sock without looking at the color. What is the numerical probability of flora picking out a blue sock?
Answers
The numerical probability of Flora picking out a blue sock is 1 out of 6, or approximately 0.1667, or 16.67%.
To calculate the numerical probability of Flora picking out a blue sock, we need to consider the total number of socks and the number of blue socks in the drawer.
Given:
Total number of socks = 12
Number of red socks = 9
Number of blue socks = 2
Number of green socks = 1
The probability of Flora picking a blue sock can be calculated as the ratio of the number of blue socks to the total number of socks:
Probability of picking a blue sock = Number of blue socks / Total number of socks
Probability of picking a blue sock = 2 / 12
Simplifying the fraction, we get:
Probability of picking a blue sock = 1 / 6
