Sin(-120) in exact value

Mathematics
1 answer:
cupoosta [38]3 years ago
3 0

Step-by-step explanation:

\because \: sin \: ( -  \theta) =  - sin \:  \theta \\  \\  \therefore \: sin \: ( - 120 \degree) =  -  sin \:  120 \degree \\  \\  =  - sin \:  ( 180\degree- 60 \degree)  \\  \\  = - sin \: 60 \degree \\  \\  =  -    \frac{ \sqrt{3} }{2}  \\  \\   \purple{ \boxed{\therefore \: sin \: ( - 120 \degree) =-    \frac{ \sqrt{3} }{2} }}

An 8.0 kg block is moving at 3.2 m/s. A net force of 10 N is constantly applied on the block in the direction of its movement, u
Softa [21]

Answer:

5.02 m/s

Step-by-step explanation:

We are given that

Mass of block,m=8 kg

Initial velocity,u=3.2 m/s

Net force ,F=10 N

Distance,s=6 m

We have to find the approximate final velocity of the block.

We know that a=\frac{F}{m}

Using the formula

a=\frac{10}{8}=\frac{5}{4} m/s^2

We know that

v=\sqrt{u^2+2as}

Using the formula

v=\sqrt{(3.2)^2+2\times \frac{5}{4}\times 6}

v=5.02 m/s

Mrs. Palmer asks her students to find the area of the tops of their desks.
xxTIMURxx [149]

Answer:

12 square feet

Step-by-step explanation:

The shape of the top of the desk is a trapezoid.

A = (b1 + b2)h/2

A = (5 ft + 3 ft)(3 ft)/2

A = (8 ft)(3 ft)/2

A = 24 ft^2/2

A = 12 ft^2

Answer: 12 square feet

Which equation represents a linear function rule for the following set of ordered pairs?
d1i1m1o1n [39]

The equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.

<h3>What is the Equation of a Linear Function?</h3>

Equation of a linear function, where m is the slope and b is the y-intercept, is expressed as y = mx + b.

Find the slope (m):

Slope (m) = change in y/change in x = (-7 -(-4)) / (3 - 2)

Slope (m) = -3/1 = -3

Find b by substituting m = -3 and (1, -1) = (x, y) into y = mx + b:

-1 = -3(1) + b

-1 = -3 + b

-1 + 3 = b

2 = b

b = 2

Substitute m = -3 and b = 2 into y = mx + b

y = -3(x) + 2

y = -3x + 2

Therefore, the equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.

What is the equation of a horizontal line passing through the point (1, 14)?
Klio2033 [76]
The equation line passing through a point is understood to be parallel to the x-axis. In this case, the equation should be expressed as y = b where b is any number. Since y = 14 in the point (1,14), the equation of horizontal line passing through this point is y = 14.
