Question 134 (plz help) (ps I luv u)

stiv31 [10]

Answer:

<B = 108 degrees

Step-by-step explanation:

<A = (Alternate Angles are congruent)

So,

6x+18 = x+93

=> 6x-x = 93-18

=> 5x = 75

Dividing both sides by 5

=> x = 15

Now,

<B = x+93

=> <B = 15+93

=> <B = 108 degrees

Over the interval [0,2pi), what are the solutions to cos(2x) = cos(x)? check all that apply

kykrilka [37]

$\cos(2x) = \cos(x)$

Solution (1)

$2x = x + 2k\pi$

$2x - x = 2k\pi$

$x = 2k\pi$

for k=0 / for k=1 / for k=-1

x=0 / x=2π / x=-2π

acc / acc / rej

solution (2)

$2x = - x + 2k\pi$

$2x + x = 2k\pi$

$3x = 2k\pi$

$x = \frac{2k\pi}{3}$

for k=0 / for k=1 / for k=-1

x=0 / x=2π/3 / x=-2π/3

acc / acc / rej

Note that i'm trying values of K which make the answer belong to our interval;

So our solution which i will represent as a set is;

S € {0,2π/3,2π}

I’m sorry but need help

arsen [322]

These are pretty easy once you get the concept.

think of random letter (x) as the term y, so in the case of p(x)=-3+4x, its just asking what is y when x equals all those values.

so p(-2) = -3 + 4(-2), since its asking to plug in -2 for x, which equals -11

p(0) = -3 + 4(0)

= -3

p(5) = -3 + 4(5)

= 17
