Using the cosine function:

$\begin{gathered} \cos (\theta)=\frac{_{\text{ }}adjacent}{_{\text{ }}hypotenuse} \\ so\colon \\ \cos (45)=\frac{b}{16} \end{gathered}$

Solve for b:

$\begin{gathered} b=16\cdot\cos (45) \\ b=8\sqrt[]{2} \end{gathered}$

Which value is a solution of the equation 2 - 8x = -6?<br> A. 1<br> B. 1/2<br> C. -1<br> D. 8

Nuetrik [128]

Answer:

A.) 1

Step-by-step explanation:

Take away 2 from both sides

So now you have -8x = -8

Divide both sides by -8 so you get positive x and 1

x = 1

Ivahew [28]

Answer:

$\boxed{0}$

Step-by-step explanation:

$3(2^3 + (4 - 2)^3 - (6 - 2)^2)$

$= 3(2^3 + 2^3 - 4^2)$

$= 3(2.2^3 - (2^2)^2)$

$= 3(2^4 - 2^4)$

$= 3(0)$

A bus makes a stop at 2:30, letting off 15 people and on 9 people. The bus makes another stop ten mins later to let off 4 more p

abruzzese [7]

If you dont know. use x as your original value. Therefore. you would have:
x - 15 + 9
after the second stop you would have:
(x - 15 + 9) - 4

So your answer would either be...
There was ______ more people on the bus before 2:30 than there was after the second stop.
There was ______ more people on the bus after the second stop than there was before 2:30.
