Answer:

Step-by-step explanation:

The geometric mean of 2 values a and b is $\sqrt{ab}$

The 7 th term is the geometric mean of the 6 th and 8 th terms

Hence

$a_{7}$ = $\sqrt{6(216)}$ = 36 → A

What is the value of a+ by when a= 7, b= and c= 1/2 ?

Marat540 [252]

Answer:

a = 7

b =?

c = 1/2

a + by = 0

7 + b × 1/2 = 0

7 + 1/2 b = 0

1/2 b = - 7

b = -7 × 2

b = - 14

a + by

= 7 + - 14 × 1/2

= 7 -14/2

= 7 - 7

= <u>0</u>

Step-by-step explanation:

Id.k if you forgot to write the value of b or not, since the value of b is not given, this will be ur answer.

Determine the measure of ∠Q, rounded to the nearest tenth of a degree.<br> images attached.

const2013 [10]

Answer:

Step-by-step explanation:

Using the Sine rule in Δ QRS , that is

$\frac{q}{sinQ}$ = $\frac{r}{sinR}$ , that is

$\frac{15}{sinQ}$ = $\frac{12}{sin50.1}$ ( cross- multiply )

12× sinQ = 15 × sin50.1° ( divide both sides by 12 )

sinQ = $\frac{15sin50.1}{12}$ , thus

Q = $sin^{-1}$ ( $\frac{15sin50.1}{12}$ ) ≈ 73.5° ( to the nearest tenth )
