Answer:

11 hours

Step-by-step explanation:

27 miles per hour. 297/27 equals 11. to double check 11 times 27 equals 297.

Which graph has the same end behavior as the graph of f(x) = –3x3 – x2 + 1?

kaheart [24]

Given equation is f(x)=-3x^3-x^2+1

We have to identify the graph that has same end behaviour as of given equation.

It seems that you have missed to attach the given graph in question. So i will explain about how to find correct graph.

Given function has highest exponent 3 so that means degree = 3

which is an odd number.

We know that graph of odd degree polynomial always starts and ends in opposite direction.

Leading coefficient of given function is -3 which is negative.

We know that when leading coefficient is negative then graph starts from top.

Hence graph of given function will start from top and go to the bottom as shown in picture.

Now any given graph which opens from up and ends in bottom will be answer.

All polynomials having odd degree and negative leading coefficient will also have similar graph.

Andrew has a fish tank in the shape of a rectangular prism, and he needs to know the volume of water necessary to fill the tank.

Alex

Answer:

The correct option is D.

Step-by-step explanation:

Domain is the set of all posible

The volume of a rectangular prism is

$V=\text{Base area}\times height$

where,

$\text{Base area}=length\times width$

Dimensions can not be negative. So, the width and volume are always positive.

From the graph it is noticed that

In interval $(-\infty, -5)$ , width and volume is negative, so $(-\infty, -5)$ interval is not the domain.

In interval (-5,0), width is negative, so (-5,0) interval is not the domain.

In interval (0,3), volume is negative, so (0,3) interval is not the domain.

In interval $(3,\infty)$ , width and volume is negative, so $(3,\infty)$ interval is not the domain.

Therefore the correct option is D.

In order to produce 100 oatmeal cookies, Goodie Cookie Co. incurs an average total cost of $0.25 per cookie. The company’s margi

amm1812

Answer:

Option D : $20

Step-by-step explanation:

The average total cost to produce 100 oatmeal cookie = $0.25 per cookie.

So, total cost for 100 cookies will be = $0.25\times100=25$ dollars

The company’s marginal cost is constant at $0.10 for all oatmeal cookies produced.

When 50 cookies are produced, the marginal cost will be = $0.10\times50=5$ dollars

The total cost to produce 50 oatmeal cookies = $25-5=20$ dollars

Hence, option D is correct.

A clock is showing the time as exactly 3:00 p.m. and 25 s. Because a full minute has not passed since 3:00, the hour hand is poi

Grace [21]

I had to read this a couple of times to see this was not about time, but is a right triangle problem. If the hour hand is at three, let us consider that a leg of a right triangle, we will consider the hypotenuse as the second hand.
Sketch the picture.

The hypotenuse is 9 cm. the angle is found by:

the (hour hand) is pointing directly at the 12. I expect you mean the minute hand. The angle between the minute hand and the second hand is 25/60*360 = 150 which make the angle between the hour hand and the second hand. 150 -90 =60

so the second hand and the hour hand gives us a right triangle, with a 60 degree angle and a hyp. of 9 cm.

cos 60 = x/9

9 cos 60 =x
<span>
x = 4.5 cm
