Use the law of sines to find the length of side c (answer as soon as possible)

Mathematics
1 answer:
Serggg [28]4 years ago
7 0

Answer:

D

Step-by-step explanation:

Using the law of sines in ΔABC, then

\frac{c}{sinC} = \frac{a}{sinA}

Substituting in values gives

\frac{c}{sin31.6} = \frac{25}{sin38} ( cross- multiply )

c × sin38° = 25 × sin31.6° ( divide both sides by sin38° )

c = \frac{25(sin31.6)}{sin38} ≈ 21.28 → D

What is the explicit formula for this sequence -7, -4, -1, 2, 5
Nataliya [291]

Answer:

\large\boxed{a_n=3n-10}

Step-by-step explanation:

It's an arithmetic sequence.

-4-(-7)=-4+7=3\\-1-(-4)=-1+4=3\\2-(-1)=2+1=3\\5-2=3

The difference is constant.

The explicit formula of an arithmetic sequence:

a_n=a_1+(n-1)d

Substitute:

a_1=-7,\ d=3

a_n=-7+(n-1)(3)          <em>use distributive property</em>

a_n=-7+3n-3\\\\a_n=3n+(-7-3)\\\\a_n=3n-10

6 Which equation has a solution of s = 9.5 ? F -5s = -47.5 G -3 + s = 12.5 H --2s 19 J –1 + s = 10.5​
earnstyle [38]

Answer:

F. -5s = -47.5

Step-by-step explanation:

F. -5s = -47.5

s = -47.5 / -5

s =  9.5

This is the correct option

G. -3 + s = 12.5

s = 12.5 + 3

s = 15.5 (Incorrect option)

J. –1 + s = 10.5​

s = 10.5 + 1

s = 11.5 (Incorrect option)
