Answer:

b ≈ 9.5, c ≈ 14.7

Step-by-step explanation:

Using the Sine rule in Δ ABC, that is

$\frac{a}{sinA}$ = $\frac{b}{sinB}$ , substitute values

$\frac{7}{sin23}$ = $\frac{b}{sin32}$ ( cross- multiply )

b × sin23° = 7 × sin32° ( divide both sides by sin23° )

b = $\frac{7sin32}{sin23}$ ≈ 9.5 ( to the nearest tenth )

Also

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

$\frac{7}{sin23}$ = $\frac{c}{sin125}$ ( cross- multiply )

c × sin23° = 7 × sin125° ( divide both sides by sin23° )

c = $\frac{7sin125}{sin23}$ ≈ 14.7 ( to the nearest tenth )

F(x) = 5 F(x)= x2+4 solve this

Viktor [21]

Step-by-step explanation:

replaced f(x) with 5

5= x^2 +4

5 -4 = x^2

1 = x^2

take the square root on both sides

- 1 or 1 = x

Write the algebraic expression that represents the following: The difference of thirteen and a number

katrin2010 [14]

$\Large\texttt{Answer}$

$\bold{n-13}$

$\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}$

$\Large\texttt{Process}$

⇨ Again letting n be the number

$\bold{n}$

⇨ Subtract 13 from n

$\bold{n-13}$

*unlike addition, the order DOES matter, because

$\bold{n-13\ne 13-n}$

Hope that helped
