Find the solutions/ show steps<br> Sin2x+sin(4x) =0

NISA [10]

Answer:

x = 0, π/3, π/2, 2π/3, π, 4π/3, 3π/2, 5π/3

Step-by-step explanation:

sin(2x) + sin(4x) = 0

Use double angle formula.

sin(2x) + 2 sin(2x) cos(2x) = 0

Factor.

sin(2x) (1 + 2 cos(2x)) = 0

Solve.

sin(2x) = 0, cos(2x) = -½

2x = 0, 2π/3, π, 4π/3, 2π, 8π/3, 3π, 10π/3

x = 0, π/3, π/2, 2π/3, π, 4π/3, 3π/2, 5π/3

What is the sum of the finite arithmetic series (-5)+0+5+10+ ......+65

Alex17521 [72]

If you want to solve this problem using formulas, there are two important formulas:

t1 = first term = -5

tn = nth term = last term = -5

n = numbr of terms

Sn = sum of the n terms

tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)

65 = -5 + 5n - 5

65 = -10 + 5n

75 = 5n

n = 15

Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2

Sn = 450

So ur answer rounds up to 450

Letter c

The average winter snowfall in City A is 105 cm. City B usually gets 2.8 m of snow each winter. Compare the yearly snowfall in t

Inessa [10]

We see that city A gets 105 cm of snow while city B gets 2.8 m. The first thing we do is make both measurements equal to each other. This can be done by either converting city A's 105 centimeters to meters or city B's meters to centimeters. But the question specifically calls for both, so we get both measurements.

City A: 105 centimeters OR 1.05 meters
City B: 280 centimeters OR 2.8 meters

Now that we know the measurements, let's look at the first problem. (A) asks for the difference in one year in meters. The difference of course means subtraction. Now it's here where I personally am confused on what it asking for in terms of which city is it asking for us to subtract from, but using an educated guess, I'll say we're subtracting from city B because if we were to subtract from city A, we'd have a negative, and you can't have a negative amount of snow, only 0 snow.

So once again, for question (A), we subtract 1.05 from 2.8 (2.80 - 1.05) and we get 1.75 meters of snow.

Question (B) asks for the difference during two years in centimeters, so we multiply both measurements by 2 and use the centimeter measurements. (105 x 2 = 210) (280 x 2 = 560) Subtract 560 from 210 (560 - 210) and we get 350 centimeters.

So your answers are: (A) 1.75 meters (B) 350 centimeters

I hope this helps!
