Mathematics
1 answer:
Oxana [17]3 years ago
7 0

Answer:

Yes

Step-by-step explanation:

1) Cos 300 = Cos (360 - 60) = Cos 60    {Cos 360 - theta = Cos theta}

                                              = 1/2

Sin 300 = Sin (360 - 60) = -Sin 60 = \frac{-\sqrt{3}}{2}

3) 3π/4 = 3*180/4 = 135

Cos 135 = Cos (90 + 45) = -Cos 45 = \frac{-\sqrt{2}}{2}

Sin 135 = Sin (90 + 45) = Sin 45 = \frac{\sqrt{2}}{2}

Solve. −35x+15>720 Drag and drop a number or symbol into each box to show the solution.
vampirchik [111]

Answer:

The solution of the inequality - 35x + 15 > 720  is x

Step-by-step explanation:

Consider the given inequality

- 35x + 15 > 720

Subtract both side by 15 , we get

- 35x + 15 - 15 > 720 - 15

- 35x > 705

Multiply both sides by -1 (Reverse the inequality )

(-35x)(-1) < 705 (-1)

35x < -705

Now, divide both side by 35

\frac{35x}{35}=\frac{-705}{35}

\Rightarrow x=\frac{-141}{7}

Thus, the solution of the inequality - 35x + 15 > 720  is x

Due tomorrow Please help!!
anastassius [24]

Answer:

A

\frac{1}{8} = \frac{b}{4^{2} }

b = \frac{1}{8} × 4^{2}

b = \frac{4^{2} }{8}

then b = \frac{c^{2} }{a} that is ORANGE

B

-2 - v = -7

v = -7 +2

then v = k + m that is BROWN

C

\frac{14}{q} = \frac{-7}{-4}

q = \frac{14 * -4 }{-7}

then q = \frac{ps}{r} that is YELLOW

D

4m + 2(n) = 5 (n)

4m = 5 (n) - 2n

4m = 3n

m = \frac{3n}{4}

then m =  \frac{3n}{4} that is RED

E

-8 = \frac{x}{-5} - 6

\frac{x}{-5} = -8 + 6

x = -5 (-8 + 6)

then x = y( w + z ) that is LIGHT GREEN
