Answer:

$159.95

Step-by-step explanation:

Let price of trumphet be defined by x

price of clarinet = $139.95

Number of clarinets sold = 19

Earning through clarinets' sale = 19*139.95 = 2659.05

Total earning of store = $4578.45

Earning through trumphets' sale = 4578.45 - 2659.05 = 1919.40

price of one trumohet = \frac{1919.40}{12} = 159.95

price of clarinet = $159.95

Answer:

90

Step-by-step explanation:

You need to simply add all the given numbers together and enter the missing number that'll make the total 0. So:

-75 + (-25) = -100

-100 + 10 = -90

-90 + <u>90</u> = 0

Thus, adding a 90 in the empty box will make it 0.

Find the equation of the tangent line to the curve y = 2sinx at the point (pi/6,1). The equation of this tangent line can be wri
mixas84 [53]
Y = mx + b

1) m = slope of the tangent line = derivative at the point (pi/6, 1)

Function: y = 2sinx

Derivative: y ' = 2cosx

evaluate at x = pi/6=> y ' = 2cos(pi/6) = √3

2) equation using the slope and the point (pi/6, 1)

y - 1 = √3 ( x - pi/6 )

y = √3 x - √3(pi/6) +1 =√3 x + 0.093

y = √3 x + 0.093

m = √3, b = 0.093
