For positive acute angles AA and B,B, it is known that \cos A=\frac{24}{25}cosA= 25 24 and \sin B=\frac{11}{61}.SinB= 61 11 . Find the value of \sin(A+B)sin(A+B) in simplest form.
Answers
Answer:
684/1525
Step-by-step explanation:
Given
cosA = 24/25
SinB = 11/61
Sin(A+B) = SinAcosB + CosAsinB
Get SinA
Since
Cos A = adj/hyp
adj = 24
hyp = 25
opp² = 25² - 24²
opp² = 625 - 576
opp² = 49
opp = √49
opp = 7
sinA = opp/hyp
sinA = 7/25
Also if SinB = 11/61
opposite = 11
Hypotenuse = 61
adj² = 61² - 11²
adj² = 3,721 - 121
adj² = 3600
adj = √3600
adj = 60
Cos B = adj/hyp
CosB = 60/61
Sin(A+B) = SinAcosB + CosAsinB
Sin(A+B) = 7/25(60/61) + 24/25(11/61)
Sin(A+B) = 420/1,525 + 264/1,525
Sin(A+B) = 684/1525

A box measures 18 inches wide by 9 inches deep. The height of the box is 1 1/2 feet. What is the volume of the box? Remember if ft is equivalent to 12 in.
Answers
Answer: 2,916 inches³
Step-by-step explanation:
The volume of a box is:
= Length * Width * Height
But all of these have to have the same units for it to work. This means that the height of the box will have to be converted to inches :
1 ft is 12 inches so:
= 1¹/₂ * 12
= 3/2 * 12
= 18 inches
Volume is therefore:
= 18 * 9 * 18
= 2,916 inches³

If U is the set of all natural numbers less than 10, A is its subset containing all natural numbers less than 6 and B⊂U consists of all natural numbers greater than 4 (and of course smaller than 10), draw Venn diagram showing these sets. List elements of sets A, B, their union, and their intersection.
Please answer fast
Answers
Step-by-step explanation:
U would be {0,1,2,3,4,5,6,7,8,9}
A would be {0,1,2,3,4,5}
and B would be {5,6,7,8,9}
The union would be {0,1,2,3,4,5,6,7,8,9}
And their intersection {5}
The elements of sets are A = { 1,2,3,4,5 }, B = { 5,6,7,8,9,10 }, A ∪ B = { 1,2,3,4,5,6,7,8,9,10} and A ∩ B = { 5 }.
What is a set?"A set is a collection of objects. The objects are called the elements of the set. If a set has finitely many elements, it is a finite set, otherwise it is an infinite set".
For the given situaton,
Union set U = { 1,2,3,4,5,6,7,8,9,10 }
Set A = { 1,2,3,4,5 }
Set B = { 5,6,7,8,9,10 }
Union of sets A and B is [tex]A[/tex] ∪ [tex]B[/tex] = { 1,2,3,4,5,6,7,8,9,10}
Intersection of sets A and B is [tex]A[/tex] ∩ [tex]B[/tex] = { 5 }
The venn diagram below shows the sets U, A and B.
Hence we can conclude that the elements of sets A, B, A ∪ B, A ∩ B are listed.

A circle has a center at A (-3,4) and radius of 4 units. What is the equation of the circle? Show work!
Answers
Answer:
The equation of the circle is (x+3)^2 + (y-4)^2 = 16.
Step-by-step explanation:
The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by (x-h)² + (y-k)² = r²
Where (h, k) = center coordinates and r = radius.

Farmer Brown has 42 animals, which are cows and chickens. They have a total of 120 legs. Write a system of equations, show your work, and solve for the number of chickens Farmer Brown has.
Answers
Answer:
The system of equations is:
x + y = 42
4x + 2y = 120
And there are 24 chickens.
Step-by-step explanation:
We know that the total number of cows (x) plus the total number of chickens (y) is 42, because Farmer Brown has 42 animals.
We also know that cows (x) have 4 legs and so 4 times the number of cows is the number of cow legs. And chickens (y) have 2 legs, so the number of chickens times two represents the total chicken legs. The sum of 4x + 2y is 120 because there are 120 legs in total.
To solve the system of equations, first solve each equation for y.
In the first equation:
x + y = 42
Subtract x from both sides to isolate y.
y = 42 - x
Second equation:
4x + 2y = 120
Subtract 4x from both sides
2y = 120 - 4x
Divide both sides by 2
y = 60 - 2x
Now that the y's are isolated in both equation, you can put them into 1 equation. Where y = y:
y = 42 - x
y = 60 - 2x
42 - x = 60 - 2x
Add 2x to both sides
42 + x = 60
Subtract 42 from both sides
x = 18
Since x is the number of cows, we know that Farmer Brown has 18 cows.
Now we can substitute the x value into one of the equations:
y = 42 - x
y = 42 - (18)
y = 24
The number of chickens is represented by y, so there are 24 chickens.
