Answer:
P(-0.2, 2.2)
Step-by-step explanation:
You want the coordinates of point P that divides AB into segments with the ratio AP/PB = 3/7. The end points are A(-2, 1) and B(4, 5).
Dividing pointThe point that divides AB in the ratio m/n is ...
P = (mB +nA)/(m+n)
P = (3(4, 5) +7(-2, 1))/(3+7) = (12 -14, 15 +7)/10
P = (-0.2, 2.2)
Find the mass and center of mass of the lamina that occupies the region D and has the given density function p. D is bounded by the parabolas y = x2 and x = y2; p(x, Y) = 19 x
The mass and center of mass of the lamina that occupies the region D and has the given density function p is 57/14 and (14/27, 7/18) respectively.
The center of mass (x―,y―) of a lamina with density function ρ(x,y) is given by
x = M(y)/m, y = M(x)/m
Where, m=∫∫[tex]_{D}[/tex]ρ(x,y)dA
Mx=∫∫[tex]_{D}[/tex] yρ(x,y)dA
My=∫∫[tex]_{D}[/tex] xρ(x,y)dA
Given that, D is bounded by y=x^2 and x=y^2
And ρ(x,y)=19√x
Now, for the point of intersection of y=x^2,x=y^2
we have,
x = (x^2)^2
x = x^4
Subtract x^4 on both side
x - x^4 = 0
x(x^3−1) = 0
x = 0, 1
Now, x=0⇒y=0 and x=1⇒y=1
The points of intersection are (0,0),(1,1)
So, the region D can be written as
D={(x,y): 0≤x≤1, x^2≤y≤x}
So,
m = [tex]\int_{0}^{1}\int_{x^2}^{\sqrt x}19 \sqrt xdydx[/tex]
m = [tex]19\int_{0}^{1}\sqrt{x}[y]^{x^2}_{x}dx[/tex]
m = [tex]19\int_{0}^{1} \sqrt x(\sqrt{x}-x^2)dx[/tex]
m = [tex]19\int^{1}_{0}(x-x^{5/2})dx[/tex]
m = [tex]19[\frac{x^2}{2}-\frac{x^{7/2}}{7/2}]^1_{0}[/tex]
m = [tex]19[\frac{1}{2}(1^2-0)-\frac{2}{7}(1^{7/2}-0)][/tex]
m = 19(1/2−2/7)
m = 57/14
m = 5714
Now,
Mx = [tex]\int_{0}^{1}\int_{x^2}^{\sqrt x}(19xy)dydx[/tex]
Mx = 19[tex]\int^{1}_{0}x[\frac{y^2}{2}]_{x^2}^{\sqrt x}dx[/tex]
Mx = [tex]\frac{19}{2}\int^{1}_{0}x[(\sqrt{x})^2-(x^2)^2}dx[/tex]
Mx = [tex]\frac{19}{2}\int^{1}_{0}(x^2-x^5)dx[/tex]
Mx = [tex]\frac{19}{2}[\frac{x^3}{3}-\frac{x^6}{6}]_{0}^{1}[/tex]
Mx = [tex]\frac{19}{2}[\frac{1}{3}(1^3-0)-\frac{1}{6}(1^6-0)][/tex]
Mx = 19/2 (1/3−1/6)
Mx = 19/12
And
My = [tex]\int^{1}_{0}\int_{x^2}^{\sqrt x}x(19\sqrt{x})dydx[/tex]
My = [tex]19\int_{0}^{1}x^{3/2}[y]^{\sqrt{x}}_{x^2}dx[/tex]
My = [tex]19\int_{0}^{1}x^{3/2}(\sqrt{x}−x^2)dx[/tex]
My = [tex]19\int_{0}^{1}(x^2-x^{7/2})dx[/tex]
My = [tex]19[\frac{x^3}{3}-\frac{x^{9/2}}{9/2}]_{0}^{1}[/tex]
My = 19[1/3(1^3−0)−2/9(1^{9/2}−0)]
My = 19(1/3−2/9)
My = 19/9
So, x = My/m
x = (19/9)/(57/14)
x = (19/9)×(14/57)
x = 14/27
y = Mx/m
y = (19/12)/(57/14)
y = (19/12)×(14/57)
y = 7/18
Therefore, the solutions are (14/27, 7/18).

How do you find the altitude?
The measure of the altitude of the triangle shown in the figure given below is 15 inches .
The Altitude of the triangle is defined as the perpendicular distance from the top vertex of the triangle to the base of the triangle.
Also , the altitude of a right triangle is same as height of triangle.
If in the right triangle , the length of altitude is "a units" ,
the length of base is "b units " , and the length of hypotnuse is "c units" .
So , the altitude can be calculated using the formula : a = √(c² - b²) .
from the figure given below , we can see that , c = 25 and b = 20
we get , a = √(25² - 20²)
a = √(625 - 400)
a = √225 = 15 inches .

to measure a stone face carved on the side of a mountain, two sightings feet from the base of the mountain are taken. if the angle of elevation to the bottom of the face is and the angle of elevation to the top is , what is the height of the stone face?
The stone face is approximately 57.8512 feet in height.
What is the height?Height is a mathematical term that refers to the vertical distance between an object's top and base.
Sometimes, it has the designation "altitude."
The measurement of an item along the y-axis in coordinate geometry is referred to as height in geometry.
So, let h be the stone's face's height.
One sight is 750 feet away from the mountain's base, and there is a 33° elevation difference between it and the bottom of the face.
The distance between the mountain's base and the base of the stone face
= 750 * tan33°
= 750 * 0.64940759319
= 487.055694898
A different location, which is 36° in elevation and 750 feet from the mountain's base, can be seen from the summit of the face.
The separation between the mountain's base and the top of the stone face = (h + 487.055694898) ft
Now, using trigonometry:
h + 487.055694898/750 = tan36°
h + 487.055694898 = 0.726542525 * 750
h = 544.906896004 - 487.055694898 = 57.8512011059 = 57.8512
Therefore, the stone face is approximately 57.8512 feet in height.

find the area of the region enclosed by the inner loop of the curve. r = 4 + 8 sin θ
The area of the region enclosed by the inner loop of the curve is 4π/3.
The term area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Here we have Given the following values,
r = 4 + 8 sin (θ)
Now, we have to substitute the value of r = 0, then we get
⇒ 0 = 4 + 8 sin (θ)
⇒ 8 sin (θ) = -4
⇒ sin θ = -1/2
⇒ θ = -π/6
Therefore, the limit lies in the interval -π/6 to + π/6
Now, the value of Area of polar region is calculated as,
=> A = ∫
Now, by Substituting the values
A=∫π/6−π/6 (4 + 8 sin (θ)) dθ
When we simplify this one then we get the value as,
=> A = 8 [θ + 1/6 sin6θ]
Apply the limit value, then we get
=> A = 8[(π/6 + 0) - (0 + 0)]
=> A = 4π/3

How do i solve this?
The x-intercept and coordinate of the vertex of the given parabola will be x = 1,7 and (4,-9) respectively.
What are coordinates?A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
As per the given parabola,
y = x² - 8x + 7
At x-intercept, y = 0
x² - 8x + 7 = 0
x² - 7x - x + 7 = 0
x(x - 7) - (x - 7) = 0
(x - 1)(x - 7) = 0
x = 1,7
For the vertex, the slope will be zero,
y' = 2x - 8 + 0 = 0
2x = 8
x = 4
Thus, y = 4² - 8 x 4 + 7
y = -9
Thus, the coordinate of the vertex is (4,-9)

How to solve 4x 5y 20?
The solution to 4x 5y 20 is 4x + 5y = 20. This can be solved by subtracting 5y from both sides of the equation, giving 4x = 20 - 5y, and then dividing both sides of the equation by 4, giving x = (20 - 5y) / 4.
4x 5y 20 is not an equation and thus cannot be solved. However, if you are looking to find the product of 4x and 5y, then the answer would be 100xy. To calculate this, you must multiply 4x by 5y. This will give you 20x + 20y, which can be simplified to 100xy. To make sure that you reach the correct answer, it is recommended to double check your work. This can be done by taking the inverse of the equation, which would be dividing 100xy by 4x and 5y. If done correctly, you will end up with the same numbers you started with: 4x and 5y.

through a point on the hypotenuse of a right triangle, lines are drawn parallel to the legs of the triangle so that the triangle is divided into a square and two smaller right triangles. the area of one of the two small right triangles is $m$ times the area of the square. find the ratio of the area of the square to the area of the other small right triangle in terms of $m.$
Option d is Correct. The other ratios of right triangle's area is 1/4 of the square's size in terms of area.
Two right triangles are similar, as demonstrated in mathematics. It follows that the triangles' side ratios are equal. The triangle's height with area m is 2m in the figure because A = 1/2bh = h/2. The base of the other triangle is x, therefore 2m/1 = 1/x. Please see the file that is provided for the figure, which is X = 1/ 2m.
Area of triangle = 1/2 * base * height
The area of that triangle, which is determined by the relationship between its area and the area of the square, is
= 1/2 × 1 × 1/2m = 1/4m

A school cafeteria wants to find out what combinations of food and beverage students are ordering. the probability that a student ordered a hamburger and a Slurpee is 19 over 137.Option D
What is probability?Generally, To find the probability that a student ordered a hamburger and a Slurpee, we need to divide the number of students who ordered a hamburger and a Slurpee by the total number of students.
From the table, we can see that 19 students ordered a hamburger and a Slurpee.
There were a total of 38 + 12 + 14 + 18 + 28 + 7 + 23 = 137 students in the cafeteria.
Therefore, the probability that a student ordered a hamburger and a Slurpee is 19/137, or about 0.14.
Therefore, the correct answer is d) 19 over 137.

what is the value of cos15 cos45 - sin15 sin45
please help me!
Answer:
1/2
Step-by-step explanation:
(Solving cos first)
= cos15 cos 45
= (√6 + √2)/4 * (√2) / 2
= (1 + √3) / 4
(solving sin)
= sin15 sin45
= (√6 - √2)/4 * (√2) / 2
= (-1 + √3) / 4
(Subtracting both)
= (1 + √3) / 4 - (-1 + √3) / 4
= 1/2
I hope my answer helps you.
Answer:
(solving sin)
= sin15 sin45
= (√6 - √2)/4 * (√2) / 2

Answer:
56 teddy bears
Step-by-step explanation:
If each teddy bear weighs 1/4 pounds, then the total weight of teddy bears that can be put on the display is 1/4 pounds * X teddy bears, where X is the number of teddy bears.
The maximum weight the display can hold is 14 pounds, so we need to find the value of X that satisfies the equation: 1/4 pounds * X teddy bears = 14 pounds.
Dividing both sides of the equation by 1/4 pounds, we get: X teddy bears = 14 pounds / 1/4 pounds = 56 teddy bears.
Therefore, the employee can put 56 teddy bears on the display.
Answer: 56 teddy bears on the display.
Step-by-step explanation: We can find the maximum number of teddy bears that can be put on the display by dividing the maximum weight of the display by the weight of each teddy bear. Since each teddy bear weighs 1/4 pounds and the display can hold 14 pounds, we can put a maximum of 14 / (1/4) = <<14/(1/4)=56>>56 teddy bears on display.
