Solve the equation 5x + 7y = 35 for y.

erastovalidia [21]

Answer:

D. y = -5/7x + 5

Step-by-step explanation:

5x + 7y = 35

-5x -5x

7y = 35 - 5x

/7 /7 /7

y = 35/7 - 5/7 x

y = 5 - 5/7x

What is an equation for a sine curve with amplitude 2, and period 4pi radians ?

Nezavi [6.7K]

1. a sine curve with amplitude 2, and period 4pi radians

the general equation of the sine curve ⇒⇒ y = a sin (nθ)
where: a is the amplitude and n = 2π/perid
∵ amplitude 2, and period 4pi radians

∴ y = 2 sin (θ/2)

The correct answer is option D. y = 2 sin (θ/2)
===========================================

2.The period and amplitude of the function ⇒⇒ y = 5 cos 2θ

comparing with y = a cos nθ

where : a is the amplitude and n = 2π/period
amplitude = 5 , period = 2π/n = 2π/2 = π


The correct answer is option B. Period: pi radians: Amplitude:5

============================================================
3. tan (2π/3) = tan 120° = -√3
120° lie in the second quadrant and its reference angle = 180° - 120° = 60°
tan function in the second quadrant is negative
∴ tan 120° = - tan 60 = -√3

The correct answer is C. -sqrt3

=====================================================
4. Tan 5π/6 = tan 150° = -(√3)/3

150° lies in the second quadrant and its reference angle = 180° - 150° = 30°
tan function in the second quadrant is negative
∴ tan 150° = - tan 30 = -(√3)/3

The correct answer is B.-sqrt3/3

Road trippin' with my two favorite allies

Fully loaded we got snacks and supplies

It's time to leave this town, it's time to steal away

Let's go get lost anywhere in the U.S.A.

Let's go get lost, let's go get lost...

Blue you sit so pretty west of the one

Sparkle light with yellow icing just a mirror for the sun

Just a mirror for the sun

These smiling eyes are just a mirror for...

So much has come before those battles lost and won

This life is shining more forever in the sun

Now let us check our heads and let us check the surf

Staying high and dry's more trouble than it's worth in the sun

Just a mirror for the sun

These Smiling eyes are just a mirror for...

In Big Sur we take some time to linger on

We three…
