Given:
given points are X(-2,5) and Y(2,-3).
Find:
we have to find the coordinates of the point P on directed line segment XY that partitions the segment XY in such a way that the ratio of XP:PY = 4:1.
Explanation:
we will use section formula to find the coordinates of point P,
If a line XY is divided into two sections in the ratio m:n, then the x and y coordinates of point P are
\(x=\frac{mx_2+nx_1}{m+n},y=\frac{my_2+ny_1}{m+n}\)here, m = 4 and n = 1 and the points x1= -2, x2 = 2, y1 = 5 and y2= -3.
Therefore, the coordinates of point P are
\(\begin{gathered} x=\frac{4\times(2)+1\times(-2)}{4+1},y=\frac{4\times(-3)+1\times(5)}{4+1} \\ x=\frac{8-2}{5},y=\frac{-12+5}{5} \\ x=\frac{6}{5},y=\frac{-7}{5} \end{gathered}\)Therefore, the coordinates of point P are

A car travels a distance of 112km at an average Speed of 70km/h. It then Travells Further for 60km at an average Speed of 50 km/hr. Calculate for the entire Journey of the total time taken.
The total time taken for the entire journey is 2.8 hours.
To calculate the total time taken for the entire journey, we can use the formula:
Time = Distance / Speed
For the first part of the journey, the car travels a distance of 112 km at an average speed of 70 km/h. Using the formula, the time taken for this part is:
Time1 = 112 km / 70 km/h = 1.6 hours
For the second part of the journey, the car travels a further distance of 60 km at an average speed of 50 km/h. Again, using the formula, the time taken for this part is:
Time2 = 60 km / 50 km/h = 1.2 hours
To find the total time for the entire journey, we sum up the times for both parts:
Total Time = Time1 + Time2 = 1.6 hours + 1.2 hours = 2.8 hours

A six sided die is rolled 4 times. Find the probability that a 2 or 3 is rolled at least once. Round your answer to two decimal places
The probability that a 2 or 3 is rolled at least once is 0.80
Finding the probability that a 2 or 3 is rolled at least onceThe sample space of a die is
Sample space = {1, 2, 3, 4, 5, 6}
This means that
P(None 2 or 3) = 4/6
Simplify
P(2 or 3) = 2/3
By the complement rule, the probability that a 2 or 3 is rolled at least once is calculated as
P(At least once) = 1 - P(None)^4
So, we have
P(At least once) = 1 - (2/3)^4
Evaluate
P(At least once) = 0.80
Hence, the value is 0.80

The function
f(x) = 5sqrt(x + 13) + 5 has an inverse f ^ - 1 * (x) defined on the domain x < 5 Find the inverse. x >= - 13
The inverse function: \(f^{-1} (x) =\) \((\frac{x -5}{5} )^{2} -13\)
The inverse is defined on the domain x < 5 and x ≥ -13 for the original function, which means that the range of the original function is y ≥ 5.
What is a function?A function is a relationship that exists between two sets of numbers, with each input from the first set, known as the domain, corresponding to only one output from the second set, known as the range.
Given function is; \(f(x) = 5\sqrt{(x + 13)} + 5\)
To find the inverse of the given function, we first replace f(x) with y:
⇒ \(y = 5\sqrt{(x + 13)} + 5\)
Subtract 5 from both sides:
⇒ \(y -5 = 5\sqrt{(x + 13)}\)
⇒ \(\frac{(y -5)}{5} = \sqrt{(x + 13)}\)
⇒ \((\frac{y -5}{5} )^{2} = x + 13\)
⇒ \((\frac{y -5}{5} )^{2} -13 = x\)
Now we have x in terms of y, so we can replace x with f⁻¹(x) and y with x to get the inverse function:
f⁻¹(x) = \((\frac{x -5}{5} )^{2} -13\)
The domain of the inverse function is x ≥ 5, because this is the range of the original function, and we were given that the inverse is defined on the domain x < 5. However, we must also exclude the value x = 5, because the denominator of the fraction \((\frac{x -5}{5} )^{2}\) becomes zero at this value. Therefore, the domain of f⁻¹(x) is x > 5.
We were given that x ≥ -13 for the original function, which means that the range of the original function is y ≥ 5. Therefore, the domain of the inverse function becomes the range of the original function, and the range of the inverse function becomes the domain of the original function.

▸
The length of side CB to one decimal place is 89.3.
To find the length of side CB in the given triangle, we can use the sine rule. The sine rule states that in a triangle, the ratio of the length of a side to the sine of its opposite angle is constant.
In this case, we have the angle C as 53° and the side opposite to it, side CB, as the unknown. Let's denote the length of side CB as x.
According to the sine rule:
sin(C) / x = sin(A) / AB
We know that angle A is 37° and AB is 120 units. Plugging in the values:
sin(53°) / x = sin(37°) / 120
To find x, we can rearrange the equation:
x = (120 * sin(53°)) / sin(37°)
Calculating this expression gives us:
x ≈ 89.32
Rounding this value to one decimal place, the length of side CB is approximately 89.3.

.
Answer:
280 DB
Step-by-step explanation:
If the sound level of a jet plane is approximately 140 dB, the intensity of the sound of a jet plane is approximately 100dB
What is sound level?Sound level is the intensity to measure the sound. Decibels are used to quantify sound levels.
The sound level of a jet plane is expressed according to the expression given:
β = 10log(I/I0)
Given the following parameters
β = 140dB
I0 = 10^-12 W/m²
For required Intensity "I" Substitute:-
140 =10log(I/10^-12)
14 = log(I/10^-12)
10^14 = I/10^-12
I = 10^14 * 10^-12
I = 10^2
I = 100dB
Hence if the sound level of a jet plane is approximately 140 dB, the intensity of the sound of a jet plane is approximately 100dB

Yesterday you walked 2 7/10 miles on your treadmill. Today you walked 1 6/10 miles. How far did you walk in these two days? Also I need an answer that looks like this 3 4/5
Answer:
The answer is 4 3/10
Step-by-step explanation:
If you first break this question up into two steps, you first must add the whole numbers and then the fractions, like this:
2 7/10 1 6/10
First, add the whole numbers [Bold]
2 + 1
That equals the whole number 3
2 7/10 1 6/10
Next you add the fractions [Underlined]
7/10 + 6/10
this equals 13/10
Since this fraction is higher than 10/10, it equals a whole number too. This fraction, 13/10, will be simplified to 1 whole and 3/10. After simplifying this number you add the whole numbers once again resulting in 3 + 1, giving you 4. after finding this out you add your fractions back in, creating the answer of 4 3/10.

The surface covered by a rectangular field is 375 square yards. The width of the field is 10 yards longer than its length. Using factors, determine the length and the width of the field
Answer:
L= 15
W= 25
Step-by-step explanation:
w(w-10) =375
w^2-10w-375=0
w=25 or -15
Length=25-10 =15
The length and width of the rectangle field are 15 yards and 25 yards if the surface covered by a rectangular field is 375 square yards.
What is a rectangle?It is defined as the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let L and W be the length and width of the rectangle.
The area of the rectangular field is 375 square yards
W = 10 + L
As we know,
Area = LW
375 = L(10 + L)
375 = 10L + L²
L²+ 10L - 375 = 0
After solving the above quadratic equation:
L = 15 yards
L = -25 (length cannot be negative)
Plug L in the equation W = 10 + L to get the width of the rectangular field
W = 10 + 15
W = 25 yards
Thus, the length and width of the rectangle field are 15 yards and 25 yards if the surface covered by a rectangular field is 375 square yards.

The vertices of quadrilateral LMNP are L(-1 , 7), M(4,9), N(8, -1), and P(3,-3). Using the distance formula, determine the most precise classification of LMNP.
So, the most precise classification of quadrilateral LMNP is a kite.
What is equation?In mathematics, an equation is a statement that two mathematical expressions are equal. It typically contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal of solving an equation is to find the values of the variables that make the equation true. Equations are used in many areas of mathematics, science, and engineering to model relationships between quantities and to solve problems.
Here,
To classify the quadrilateral LMNP, we need to calculate the length of all four sides using the distance formula and then use those values to determine the shape of the quadrilateral.
The distance formula is given by:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Using this formula, we can calculate the length of each side of the quadrilateral as follows:
LM = √[(4 - (-1))² + (9 - 7)²] = √[5² + 2²] = √29
MN = √[(8 - 4)² + (-1 - 9)²] = √[4² + (-10)²] = √116
NP = √[(3 - 8)² + (-3 - (-1))²] = √[(-5)² + (-2)²] = √29
PL = √[(-1 - 3)² + (7 - (-3))²] = √[(-4)² + 10²] = √116
Now, we can use the values we have calculated to determine the shape of the quadrilateral. We can see that LM = NP and MN = PL, which means that opposite sides are congruent. Also, LM and MN are not equal to PL and NP, which means that opposite sides are not parallel. Therefore, LMNP is a kite.

First = tan(θ)
Second = cos(θ)
The basis trigonometry identity is
sin²(θ) + cos²(θ) = 1
Divide through the equation by cos²(θ)
So, we have
tan²(θ) + 1 = 1/cos²(θ)
Subtract 1 from both sides
tan²(θ) = - 1 + 1/cos²(θ)
Take the square root of both sides
