The daily cost of hiring a plumber, y, to work hours on a repair project can be modeled

Alex73 [517]

Answer:

[50, 410]

Step-by-step explanation:

If the plumber works 0 hours, he still charges $50, so that is the minimum of the range of charges.

If the plumber works 8 hours, his hourly charge of 8×$45 = $360 is added to his fixed charge of $50 for a total of $410. That is the maximum of the range of daily charges.

The range of the function is $50 to $410.

Need help understanding this problem please

faust18 [17]

f(g(x)) is a composite function:

$f(g(x))=f(\sqrt{x+5})=2\sqrt{x+5}-1$

Plug in <em>x</em> = 4:

$f(g(4)) = 2\sqrt{4+5}-1=2\sqrt9-1=2\cdot3-1=\boxed{5}$

so the answer is C.

Answer:

30 degrees

Step-by-step explanation:

Let Angle ABC be 2x, Angle EBC be 5x

$angle \: dbc = 90 - 2x \\ angle \: dbc \: + angle \: ebc = 180 \\ 90 - 2x + 5x = 180 \\ 3x = 90 \\ x = 30 \\ \\ angle \: dbc = 90 - 60 \\ = 30$

Find all of the zeros of the function and write the polynomial as the product of linear factors.

Tomtit [17]

Answer:

(x+6i)(x-6i)(x+1)

So the zeroes are 6i, -6i, -1

Step-by-step explanation:

Factor by grouping

h(x) = x^2(x+1) + 36(x+1)

h(x) = (x^2+36)(x+1)
