Three times the sum of half a number and 7 is 36

Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
5 0

Answer:

your answer is 19.34

Step-by-step explanation:

let the number be x

half a number = ½ x

three times means multiplied by three

so,

3( ½ x) + 7 = 36

3( ½ x) = 36 - 7

3( ½ x) = 29

½ x = 29/3

½ x = 9.67...

x = 9.67 × 2           (when we moved  ½ on the other side of the equal sign it                                      ›                               turns into 2/1 )

x = 19.34

Write the explicit formula for the geometric sequence.
My name is Ann [436]

Answer:

D

Step-by-step explanation:

the n th term ( explicit formula ) of a geometric sequence is

• a_{n} = a_{1}(r)^{n-1}

where r is the common ratio and a_{1} the first term

here r = \frac{8}{16} = \frac{16}{32} = \frac{1}{2} and a_{1} = 64, hence

a_{n} = 64(0.5)^{n-1} → D

Verify that the following equation is an identity. (1/sinx) - (1/cscx) = cscx - sinx
Anarel [89]
Manipulating the left side of the equation, we obtain:

\dfrac{1}{\sin x}-\dfrac{1}{\csc x}=\dfrac{\csc x-\sin x}{\sin x\cdot\csc x}

Using that \csc x=\dfrac{1}{\sin x}:

\dfrac{\csc x-\sin x}{\sin x\cdot\csc x}=\dfrac{\csc x-\sin x}{\sin x\cdot\dfrac{1}{\sin x}}=\dfrac{\csc x-\sin x}{1}=\csc x-\sin x\\\\\boxed{\dfrac{1}{\sin x}-\dfrac{1}{\csc x}=\csc x-\sin x}~~\blacksquare
