Answer:

Step-by-step explanation:

First, from the decimal place move right<u> two spaces</u>

<u></u>

passing up the first space which is the <u>Tenths place</u>

<u></u>

landing on the second space which is the <u>Hundreths place</u>

Next, you will look at the third space or the <u>Thousandsths place</u> and determine if it is either,
<u>5 and above</u>, in which case you increase the digit to the left by 1

<u>4 and below</u>, which is when you leave the digit to the left alone

In this case, our Thousandths place is below 4 which means we will leave it alone

Finally to finish the problem, the end of your rounded number will be cut off. Leaving you with your answer.

Answer:

<u>0.075 m/min</u>

Explanation:

You need to use derivatives which is an advanced concept used in calculus.

<u>1. Write the equation for the volume of the cone:</u>

$V=\dfrac{1}{3}\pi r^2h$

<u />

<u>2. Find the relation between the radius and the height:</u>

r = diameter/2 = 5m/2 = 2.5m

h = 5.2m

h/r =5.2 / 2.5 = 2.08

<u>3. Filling the tank:</u>

Call y the height of water and x the horizontal distance from the axis of symmetry of the cone to the wall for the surface of water, when the cone is being filled.

The ratio x/y is the same r/h

x/y=r/h

y = x . h / r

The volume of water inside the cone is:

$V=\dfrac{1}{3}\pi x^2y$

$V=\dfrac{1}{3}\pi x^2(2.08)\cdot x\\\\\\V=\dfrac{2.08}{3}\pi x^3$

<u>4. Find the derivative of the volume of water with respect to time:</u>

$\dfrac{dV}{dt}=2.08\pi x^2\dfrac{dx}{dt}$

<u>5. Find x² when the volume of water is 8π m³:</u>

$V=\dfrac{2.08}{3}\pi x^3\\\\\\8\pi=\dfrac{2.08}{3}\pi x^3\\\\\\ 11.53846=x^3\\ \\ \\ x=2.25969\\ \\ \\ x^2=5.1062$ m²

<u>6. Solve for dx/dt:</u>

$1.2m^3/min=2.08\pi(5.1062m^2)\dfrac{dx}{dt}$

$\dfrac{dx}{dt}=0.03596m/min$

<u />

From y/x = h/r = 2.08:

$y=2.08x\\\\\\\dfrac{dy}{dx}=2.08\dfrac{dx}{dt}\\\\\\\dfrac{dy}{dt}=2.08(0.035964m/min)=0.0748m/min\approx0.075m/min$

That is the rate at which the water level is rising when there is 8π m³ of water.

Casey bought a 15.4 pound turkey and an 11.6 pound ham for Thanksgiving and paid $38.51.

White raven [17]

Answer:

h = 1.74

t = 1.19

Step-by-step explanation:

15.4t + 11.6h = 38.51

10.2t + 7.3h = 24.84

15.4•t + 11.6•h = 38.51

10.2•t + 7.3•h = 24.84

11.6h+15.4t = 38.51

7.3h+10.2t = 24.84

h = 87

= 1.74

t = 119

100

= 1.19

Hey guys my last question please answer :) peace and love guys

Vadim26 [7]

Looking at the problem statement, this question states for us to determine the range of the function that is provided in a graph is. Let us first determine what range is.

Range ⇒ Range is what y-values can be used in the function that is graphed. For example, if a line just goes up and down all the way to negative and positive infinity, then the range would be negative infinity to positive infinity as it includes all of the y-values in it's solutions.

Now moving back to our problem, we can see that we have a vertex at (2, -5) and that the lowest y-values is at y = -5. Therefore the y-values would be anything greater than or equal to -5 and less than infinity because the lines go forever up in the positive-y-direction.

Therefore, the option that would best match the description that we provided would be option B, -5 ≤ y < ∞.
