Answer:

AB = 6.5

Step-by-step explanation:

C = 59°

AC = 7

CD = 6

AB = ?

Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)

AB² = 7² + 6² - 2(7)(6)*Cos(59)

AB² = 85 - 43.26

AB² = 41.74

AB = √41.74

AB = 6.5 (nearest tenth)

lakkis [162]

2(7-7x) = 2x + 4
14 - 14x = 2x +4
16x = 10
x = 10/16
x = 0.625

2[-(7-7x)] = 2x + 4
-14 +14x = 2x + 4
12x = 18
x = 18/12
x = 1.5

answer:
solutions x = 0.625 and x = 1.5

Rewrite the expression in the form y^n

bazaltina [42]

Answer:

$y^6$

Step-by-step explanation:

$\frac{a^b}{a^c} = a^{b - c}$

Using this rule we have:

$\frac{y^{-7}}{y^{-13}} = y^{-7 -(-13)} = y^6$
