Answer:

2√61/19

Step-by-step explanation:

sin^2 x = 1 - cos^2 x

            =  1 - (3√13/ 19)^2

             =   1 - 117/361

              =  244/361

sin x       = √244/19

              = 2√61/19.

Answer:

x=8, -2

Step-by-step explanation:

2|x-3|-8=2

2|x-3|=10

|x-3|=5                               |x-3|=-5

x-3=5                                x-3=-5

A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If
Nataly [62]

Answer:

The function is missing in the question. The function is $ C(x) = 0.8x^2 -544x +97410 $

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$ C(x) = 0.8x^2 -544x +97410 $

Cost will be minimum when

x = -(-544)/ 2 x 0.8

  = 340

Therefore, minimum cost for unit car is

$ C(x) = 0.8x^2 -544x +97410 $

$ = 0.8(340)^2 -544(340) +97410 $

=  4930

1.) What is the measure of ∠K, to the nearest degree?
lora16 [44]
We know that
the law of sines establish
a/sin A=b/sin B

problem N 1

50/sin K=53/sin 76-------> 50*sin 76=53*sin K-----> sin K=50*sin 76/53
sin K=0.9154
K=arc sin (0.9154)--------> K=66.25°------> K=66°

the answer problem N 1 is the option
<span>c.) 66°
</span>
Problem N 2

30/sin R=35/sin 69------> sin R=30*sin 69/35-----> sin R=0.8002
R=arc sin(0.8002)-------> R=53.15°-----> R=53°

the answer problem N 2 is the option
<span>b.) 53°</span>
