Answer:
(a)105° (b)105° (c)105°
Step-by-step explanation:
The Question Image is attached and a labeled one for explanation.
(a)If the Car is travelling east from the direction point A and heads North East on Kings Avenue in the direction of E, the angle which the car makes is Angle AFE
Angle AFE=180-75=105°
(b)If a car is traveling southwest on King Avenue and is to turn left onto 3rd Street. His probable starting point is North of 3rd street, say F. The angle created is Angle FGC.
Angle AFE =Angle FGC (Corresponding Angles)
Angle FGC =105°
(c)Suppose a car is traveling northeast on King Avenue is to turn right onto 3rd Street. His starting point will be South of 3rd Street.
Angle HGD will be the angle with which it turns.
Angle HGD= Angle CGE(Vertically Opposite Angles)
Angle HGD=105°
What is the measure of the angle created by the car's turning? Explain your answer.
(b) The set {(x,y) ∈ R2 | x > 0 and x < 0} is empty.
(c) If A and B are square matrices, then AB is also square.
(d) A and B are subsets of a set S, then A∩B and A∪B are also subsets of S.
(e) For a matrix A, we define A^2 = AA.
Answer:
a) False
b) True
c) True
d) True
e) True
Step-by-step explanation:
a) Consider the sets and . Observe that A is a subset of B and but
b) Any number different of 0 can be positive and negative simultaneusly. Then doesn't exist such that . Then the set is empty.
c) If the multiplication AB is defined and A and B are square matrices with A of size nxn, then B is the size nxn and the matrix AB is the size nxn.
d) Let A and B subsets of a set S. Since each element of A and B are in S then each element of is in S. Also, if , the and then . This shows that .
e) By definition AA=A^2
Answer:
The correct options are 1, 3 and 4.
Step-by-step explanation:
It is given that Lupe has 14 stickers that she wants to give to 2 friends.
Total number of stickers Lupe has is 14.
The number of friends is 2.
She wants each friend to have the same number of stickers. It means each friend will get half of 14.
The number stickers Lupe should give to her friends is 14 divided by 2.
Write this value in fraction form.
It means the correct statements are
1. Each friend gets 14÷2 stickers.
3. Each friend gets (14)/2 stickers.
4. Each friend gets 7 of the 14 stickers.
Hence correct options are 1, 3 and 4.
B) r y=-x (x,y) -> (-y,-x)
C) r y=x (x,y) -> (y,x)
D) r y=-x (x,y) -> (y,x)
Answer:
Two legs are 7.0534230 and 9.708203932.
The acute angle is 54 degrees.
Step-by-step explanation:
For the legs, you can use these two formulas:
12*cos(36)
12*sin(36)
(Make sure you put the 36 in degrees)
For the acute angle, 90-54=36 degrees.
Answer:
The answer to your question is:
acute angle = 54°
legs 7 m y 9.7 m
Step-by-step explanation:
Data
Hypotenuse = 12 m
acute angle = 36° = a
acute angle 2 = ? = b
lengths of legs= ?
Process
The sum of the internal angles on a triangle equals 180°
a + b + 90 = 180
36 + b + 90 = 180
b = 180 - 126
b = 54°
sin Ф = opposite leg / hypotenuse
opposite leg = hypotenuse x sin Ф
opposite leg = 12 x sin 36
opposite leg = 7 m
Pythagorean theorem
c² = a² + b²
a² = c² - b²
a² = 12² - 7²
a² = 144 - 49
a ² = 95
a = 9.7 m

Answer:
Answer: B
Step-by-step explanation:
The measure of each side of the cube will be 15 inches.
The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. Volume is defined as the space occupied by an object in the three-Dimensions. All three parameters are required for the volume like length, width, and height of the cube or Cuboid
The cube has all the sides equal means that the length, width, and height of the cube will be the same. Let's suppose the length, width, and height of the cube is a.
The volume of a cube will be given by the formula:-
Volume = side³ = a³
a³ = 3375
a = ∛3375
a = ∛( 15 x 15 x 15 )
a = 15 cubic inches.
Therefore, the measure of each side of the cube will be 15 inches.

Answer:
l=w=h=15
Step-by-step explanation:
Volume of a cube= l*w*h
where l=w=h
15*15*15=3375
