SVEN [57.7K]

Answer:

The bill is $30

Step-by-step explanation:

Given

$b(x) = \left \{ {{0.10x,\ x \le 200} \atop {0.15(x - 200)\ x > 200}} \right.$

See attachment

Required

Determine the bill when KWh = 400

From the given piece-wise function.

We make use of:

$b(x) = 0.15(x - 200)$

Because $400 > 200$

Substitute 400 for x in b(x)

$b(400) = 0.15 * (400 - 200)$

$b(400) = 0.15 * 200\\$

$b(400) = 30$

The bill is $30

serg [7]

Answer:

switchy switchy

Step-by-step explanation:

sin 15 = 38/x

We need to switch the sin15 and the x by multiplying both sides by x and dividing both sides by sin 15

x = 38/sin 15
