A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3as the weight density of water.)
(A water tank shaped like a triangular prism is given. The base of the prism is at the top and a spout is located at the top of the tank. The dimensions of the tank are 9 meters long, 4 meters wide, and 4 meters deep. The spout is 3 meters long.)
Answer:
W = 1.06 MJ
Step-by-step explanation:
- We will use differential calculus to solve this problem.
- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.
- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]

To identify the true statement, I will make use of graphical method.
See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]
From the attached graph, we can see that the graph as a minimum at:
[tex](x,y) = (2,-8)[/tex]
And it opens upward.
This implies that the minimum y-value of f(x) is at -8, and it has no maximum.
In other words, the range of the function is:
[tex]f(x) \ge -8[/tex]
Hence, the true statement is option (a):
The range of f(x) is [tex]y \ge -8[/tex]

Mack beat his opponent by
SEVEn points in a game which
ends when a total of
101 points have been scored.
How many point did Mark
have
Answer:
94
Step-by-step explanation:
When a player reaches 101 points, they win. So that means that Mack reached 101 points. Since his opponent was seven points behind, we can subtract 7 from 101 to find Mark's, that is Mack's opponent's, score:
[tex]101-7=94[/tex]
Therefore, we can safely conjecture that Mark scored 94 points.
9. Use Structure Point K is of the way from |(4,-5) to L(0, -7). a. What are the coordinates of Kif n = 4? b. What is a formula for the coordinates of K for any n?
Dividing the segments, it is found that:
a) The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]b) [tex]K - J = \frac{1}{n}(J - L)[/tex]----------------------------
The endpoints are [tex]J(4,-5)[/tex] and [tex]L(0,-7)[/tex].Point K is (x,y).Since point K is [tex]\mathbf{\frac{1}{n}}[/tex] of the way from J to L, it means that:[tex]K - J = \frac{1}{n}(J - L)[/tex]
And this is the answer to option b.
----------------------------
Option a:
If [tex]\mathbf{n = 4}[/tex], it has that:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
This is applied to find both the x-coordinate and the y-coordinate of K.
----------------------------
The x-coordinate of K is x.The x-coordinate of J is 4.The x-coordinate of L is 0.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]x - 4 = \frac{1}{4}(4 - 0)[/tex]
[tex]x - 4 = 1[/tex]
[tex]x = 5[/tex]
----------------------------
The y-coordinate of K is y.The y-coordinate of J is -5.The y-coordinate of L is -7.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]y - (-5) = \frac{1}{4}(-5 - (-7))[/tex]
[tex]y + 5 = \frac{2}{4}[/tex]
[tex]y = \frac{1}{2} - 5[/tex]
[tex]y = \frac{1}{2} - \frac{10}[2}[/tex]
[tex]y = -\frac{9}{2}[/tex]
The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]

Solve the equation z^4+4z^2+16=0
Answer:
As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.
First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]
z2=−4±42−4×1×16√2×1=−4±16−64√2
=−4±−48√2=−2±12−−√i=−2±23–√i
=4(−12±3√2)i
=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2
=4e2kiπ3
As this is the value of z2 , whereas we want z , we need to take the square roots of both sides
z=4–√ekiπ3+nπ , where n∈0,1
=2e(k+3n)iπ3
=2cis((k+3n)iπ3)
As we have two values of k and two values of n , this gives us four solutions.
Writing these angles in terms of degrees, we have: 60, 120, 240 and 300
Evaluating, we end up with the four solutions
z=1±3–√i∪z=−1±3–√i
You can substitute z^2 = x,
Then you get x^2+4x+16=0
Step-by-step explanation:
z=1±3–√i∪z=−1±3–√i
You can substitute z^2 = x,
Then you get x^2+4x+16=0
Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a
X1,2=(-4+-√[16–16*4])/2
After you solve that you substitute back z^2 = x

The average yearly cumulative rainfall in Tucson by month is shown in the graph below. Does this
graph represent cumulative rainfall as a function of the day? Why or why not? What is the average
annual cumulative rainfall in Tucson? What is the approximate average rainfall in December? During
which month is average rainfall the greatest? How do you know?
Answer:
The average annual cumulative rainfall is [tex]1[/tex] inch per month.
During month of August average rain fall is greatest because slope in this month is maximum.
Step-by-step explanation:
The graph does not represent cumulative rainfall as a function of day.
Because they have average all values for month Total cumulative rainfall is [tex]12[/tex] inches.
Total period is [tex]12[/tex] month
So average annual cumulative rainfall is
[tex]$12 / 12=1$[/tex] inch per month
Average rain fall in month of December= (average cumulative rainfall in December[tex])-([/tex]average cumulative rainfall in November)
[tex]=12-11[/tex]
[tex]$=1$[/tex] inch
During month of August average rain fall is greatest because slope in this month is maximum.

gallons of gas did he buy? Let g equal the number of gallons of gas.
(1 point)
O 6.509 +2.78 = 24.00
O 2.789 -6.50 = 24.00
O 6.50g - 2.78 = 24.00
2.789 +6.50 = 24.00
Answer:
Cory bought 6.30 gallons of gas at the gas station.

total amount = cost of snacks + amount spent on gas
[tex]$\$ 24.00=\$ 6.50+\$ 2.78 \mathrm{~g}$[/tex]
