Answer:
27.37 and 9.18
Step-by-step explanation:
(4)
Using the cosine ratio in the right triangle
cos64° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )
x × cos64° = 12 ( divide both sides by cos64° )
x = [tex]\frac{12}{cos64}[/tex] ≈ 27.37 ( to the nearest hundredth )
(5)
Using the sine ratio in the right triangle
sin35° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{16}[/tex] ( multiply both sides by 16 )
16 × sin35° = x , then
x ≈ 9.18 ( to the nearest hundredth )

for all positive angles less than 360°, if csc csc (2x+30°)=cos cos (3y-15°), the sum of x and y is?
Answers
Answer:
35 degrees
Step-by-step explanation:
for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?
Let the given expression be equal to 1, hence;
csc (2x+30°)= cos (3y-15°) = 1
csc (2x+30°) = 1
1/sin(2x+30) = 1
1 = sin(2x+30)
sin(2x+30) = 1
2x+30 = arcsin(1)
2x+30 = 90
2x = 90-30
2x = 60
x = 60/2
x = 30 degrees
Get the value of y;
cos (3y-15°) = 1
3y - 15 = arccos (1)
3y - 15= 0
3y = 0+15
3y = 15
y = 15/3
y = 5
Sum of x and y;
x+y = 30 + 5
x+y = 35degrees
Hence the sum of x and y is 35 degrees

Find the equation of the straight line which passes through each of the following pairs of points.
(1,4) (3,10)
Answers
Answer:
y = 3x + 1
Step-by-step explanation:
First, find slope:
[tex]y2 - y1 / x2 - x1[/tex]
[tex]10 - 4/ 3 - 1 = 6 / 2 = 3[/tex]
Then, put the equation into point-slope form using the point (1, 4):
[tex]y - y1 = m(x - x1)[/tex]
where m is the slope
y - 4 = 3(x - 1)
If you want to put this into slope-intercept form, it would be
[tex]y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1[/tex]
Contrasting Kinetic and Thermal Energy
Answers
Answer:
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
Step-by-step explanation:
Differences:
So, the main difference between thermal and kinetic energy is that the first one is random motions of particles that you mostly can't see by eye, while the second is a unified motion of these same particles, which you can then see. As you say, kinetic energy of large objects can be converted into this thermal energy.
The difference between Kinetic and Thermal Energy is simple. Thermal Energy comes from heat which is generated by molecules moving around very fast (kinetic energy does tie in here but Thermal and Kinetic Energy are still not the same). Kinetic Energy is generated by speed and mass, and whenever an object is moving fast it has Kinetic Energy, if something is sitting still it has Potential Kinetic Energy.
Hope this helps and have a nice day.

Responder:
Por favor, consulte la explicación
Explicación paso a paso:
Para garantizar que la selección realizada sea representativa, la selección debe ser aleatoria.
1.) Se puede elegir una muestra totalmente aleatorizada de 15 integrantes de niños y niñas en igual proporción. Es decir, si toda la población tiene un 60% de niñas y un 40% de niños, entonces una muestra puede incluir;
0.4 * 15 = 6 niños
0,6 * 15 = 9 niñas
Además, la muestra se puede seleccionar asignando al azar 15 números a un trozo de papel enrollado donde se les puede pedir a todos los estudiantes que elijan. los estudiantes que eligen los trabajos numerados se utilizan como muestra.

3. A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. 12 radius 18 height
Answers
Answer:
8138.88 cubic unit.
Step-by-step explanation:
Given that,
Radius, r = 12
Height, h = 18
We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\[/tex]
So, the volume of the cylinder is 8138.88 cubic unit.
