Answer: Neither odd nor even

Step-by-step explanation:

For it to be odd, f(x)=-f(-x).

For it to be even, f(x)=f(-x)

$f(x)=3x^{5}-9\\\\f(-x)=3(-x)^{5}-9=-3x^{5}-9$

Hence, it is neither odd nor even.

a business shows a profit of $110 for selling 20 leather wallets how much profit would the business make if they sold 35 wallets

mafiozo [28]

Answer:

They would get 192.5

Step-by-step explanation:

First we need to find how much it cost per 1 so you will need to dovide 110 by 20 which equal 5.5

Then you will multiply 5.5*35 and get 192.5

Find the area of the regular polygon. Round to the nearest tenth.

JulsSmile [24]

Answer:

$110.9\ ft^{2}$

Step-by-step explanation:

we know that

If the triangle of the figure is a regular polygon

then

Is an equilateral triangle

Remember that

The equilateral triangle has three equal sides and three equal interior angles

The measure of each interior angle is 60 degrees

To find the area of the equilateral triangle apply the law of sines

$A=\frac{1}{2} b^{2}sin(60\°)$

we have that

$b=16\ ft$

substitute

$A=\frac{1}{2} (16^{2})sin(60\°)=110.9\ ft^{2}$

Alexxandr [17]

Answer:

a ) dAt/dt = 50,24 in/min

dh/dt = - 0,125 in/min

Step-by-step explanation:

The area of the top is At :

At = π*r²

a) Tacking derivatives with respect to time:

dAt/dt = 2* π*r * dr/dt

At t = t₁ r = 16 in and dr/dt = 0,5

Then

dAt/dt = 2*3,14*16*0,5 in/min

a ) dAt/dt = 50,24 in/min

b) The volume of the cylinder is:

Vc = π*r²*h ( where h is the heigh of the cylinder )

Tacking derivatives with respect to time

dVc/dt = 2* π*r*h*dr/dt + π*r²*dh/dt

But dVc/dt = 0 since the volume remains constant, then:

π*r²*dh/dt = - 2* π*r*h*dr/dt

r*dh/dt = - 2*h*dr/dt

dh/dt = - 2*0,5*2/16 in/min

dh/dt = - 0,125 in/min

PLZ HELP GEOMETRY BELOW

katen-ka-za [31]

This is known as Einstein's proof, not because he was the first to come up with it, but because he came up with it as a 15 year old boy.

Here the problem is justification step 2. The written equation

BC ÷ DC = BC ÷ AC

is incorrect, and wouldn't get us our statement 2, which is correct.

For similar triangles we have to carefully pair the corresponding parts to get our ratios right:

ABC ~ BDC means AB:BD = BC:DC = AC:BC so BC/DC=AC/BC.

Justification 2 has the final division upside down.

Write 3 < x < 9 in interval notation.

lutik1710 [3]

Answer:

(3, 9)

Step-by-step explanation:

If we have ≤ or ≥, we use brackets to signify it includes the values.

If we have < or >, we use parenthesis to signify it doesn't include the values.
