Answer:

Step-by-step explanation:

-8 - -3 equals -5, -5 - (+2) so just do -5 + 2 because the + 2 is in parenthesis and that means to do that first so that will equal -3, -3 - (6) = -9

In what direction and by how many units is the graph of f(x) = −7 sin(3x + π) − 2 vertically and horizontally shifted?

aev [14]

Answer:

Option 1. Down 2, right pi over 3.

Step-by-step explanation:

In a given function f(x) = -7 sin(3x+π)-2 we have to find the shift horizontally and vertically.

As we know in a sine equation represented as y = a sin(bx+c) +d

Amplitude of the wave = a

Period = $\frac{2\pi }{b}$

Horizontal shift = $\frac{\pi }{b}$

Vertical shift = d

From the given sine function we can get the following values

a = 7

period = $\frac{2\pi }{3}$

horizontal shift = $\frac{\pi }{3}$ in the right side since it's with positive sign.

Vertical shift = -2 down with 2 ( since it's with negative sign)

Therefore Option 1 is the correct one.

Average Inventory The DeMarco Pasta Company receives 600 cases of imported San Marzano tomato sauce every 30 days. The number of

lesya692 [45]

Answer: The average daily inventory is 200 cases.

Step-by-step explanation:

Since we have given that

N(t)=600-20√30t

We need to find the average daily inventory.

$\dfrac{1}{b-a}\int\limits^a_b {600-20\sqrt{30t}} \, dt\\\\=\dfrac{1}{30}\int\limits^{30}_0 {600-20\sqrt{30t}} \, dt \\\\=\dfrac{1}{30}[600t-\dfrac{20(30t)^\frac{3}{2}}{45}|_0^{30}\\\\=\dfrac{1}{30}[18000-\dfrac{20\times 30^3}{45}]\\\\=\dfrac{1}{30}[18000-12000]\\\\=200$

Hence, the average daily inventory is 200 cases.
