Drops = 27

First, we need to find the volume of the given tank using the following equation

Volume = Length*Width*Height\\Volume =14*9*10\\Volume =1260\\

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation

Drops = 3\frac{Volume}{140} \\Drops = 3\frac{1260}{140} \\Drops = 3(9) \\Drops = 27

Answer:

To create function h, function f was translated 2 units right , translated 4 units up and reflected across the x axis

Step-by-step explanation:

Given

f(x) = x^3

h(x) =-(x + 2)^3 - 4

Required

Complete chart

First: f(x) was translated right by 2 units

The rule of right translation is (x,y) \to (x + 2,y)

So, we have:

f'(x) = f(x + 2)

f'(x) = (x + 2)^3

Next: f'(x) was translated up by 4 units

The rule of down translation is (x,y) \to (x,y+4)

So, we have:

f"(x) = f'(x) +4

f"(x) = (x + 2)^3 +4

Lastly, f"(x) was reflected across the x-axis;

The rule of this reflection is: (x,y) \to (x,-y)

So, we have:

h(x) = -f"(x)

h(x) = -[(x+2)^3 + 4]

Remove bracket

h(x) = -(x+2)^3 - 4

Determine the equation of the line that passes through the point (7, -23)and is perpendicular to the line y=1/3x-6Enter your ans
marishachu [46]

We have a line y = 1/3x -6

We want a line that is perpendicular to this line

Perpendicular lines have slopes that multiply to -1

1/3 * m = -1

3 * 1/3 *m = -1 * 3

m = -3

The slope of the perpendicular line is -3

y = mx+b where m is the slope and b is the y intercept

y = -3x+b

We have a point on the line ( 7 ,-23)

Substitute this point into the equation

-23 = -3(7)+b

-23 = -21+b

Add 21 to each side

-23+21 = -21+21+b

-2 = b

y = -3x-2

In slope intercept form, the line perpendicular passing through (7,-23) is

y = -3x-2
