it take for all the water to drain from the tank is 1 hour 11 min 26 sec for a water tank is shaped like a vertical circular cylinder
Using the Bernoulli's laws to use the conserved energy
Solve the speed and the radio of this speed of the tank is open to the air
p₀ + ρgh₀ + ½ρv₀² = p₁ + ρgh₁ + ½ρv₁²

v²
v² = 25.68 m²/s²
v1 = 5.06 m/s
Because it is open the cylinder tank so P=0 pa so:
0 Pa + 1000kg/m³ * 9.8m/s² * 0.800m + 0 = 0 + 0 + ½ * 1000kg/m³ * v²
v² = 15.68 m²/s²
v2 = 3.96 m/s
The ratio on the air is solve using both velocities so:
R = v1/v2 = 5.06 m/s / 3.96 m/s
R = 1.27
Now to find the time it takes for the tank to drain if the tank is open to the air
dh/dt = -u
dh/dt = -v * A/A'
dh/dt = v*(.02m)²/(2.0m)² = -v / 10000
and we can further substitute for v:
dh/dt = -(1/1e4)*√[(p+9800h)/500]
Solve replacing
-(1000/49)*√(49000h) = t + C
-(1000/49)*√(49000*0.8) = 0 + C

Step-by-step explanation:
x coordinate equals 0
Y coordinate equals 6
plotted on coordinate plane attached
*drew it wrong the first time sorry
Answer:
Step-by-step explanation:
In order to plot the point, you would need to understand how coordinates work. So, the base of a coordinate is (x,y), meaning you would move your point along the x-axis by 6 units, and along the y-axis by 0 units. This would mean that on your grid, your point would be on the x-axis line (because moving 0 units just means you don't move it along that axis) and it would rest at the number 6.

Explain the term equivalent ratios?When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, 1:2 and 2:4 have the same ratio.3 sticks of butter -----> 24 cookies.
Let the number of cookies made for other stick of butter be 'y'.
Then, number cookies for the 16 sticks of butter
3/24 = 16/ y
y = 16*24 / 3
y = 128 cookies.
Again, number cookies for the 5 sticks of butter
3/24 = 5/ y
y = 5*24 / 3
y = 40 cookies.
Thus, number of cookies made by 5 sticks of buter are 40.

For positive integers N and k, define N to be k-nice if there exists a positive integer a such that a k has exactly N positive divisors. Find the number of positive integers less than 1000 that are neither 7-nice nor 8-nice.
The number of positive integers less than 1000 that are neither 7-nice nor 8-nice is 749.
N = (ke1 + 1)(ke2 + 1)· · ·(kei + 1).
This means we must have N ≡ 1 (mod k).
Yes, choose a = 2^N−1/k so that
a^k = 2^N−1
, which has N divisors.
So, we need to find the number of integers that are neither 1 mod 7
nor 1 mod 8.
We can use the principle of inclusion and exclusion.
There are [999/7]= 143 integers that are 1 mod 7.
There are [999/8]= 125 integers that are 1 mod 8.
There are [999/56 ]= 18 integers that are 1 mod 56.
By PIE, the answer is 999 − 143 − 125 + 18 = 749.
Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. The boldface Z is a common way to represent the set of integers in mathematical terms.

A department store buys 100 shirts at a cost of $1,200 and sells them at a selling price of $29 each. Find the percent markup
Answer:
To find the percent markup, we can use the following formula:
Markup = (selling price - cost price) / cost price * 100
We know that the department store buys 100 shirts at a cost of $1,200 and sells them at a selling price of $20 each.
Markup = ($20 - $12) / $12 * 100
Markup = $8 / $12 * 100
Markup = 2/3 * 100
Markup = 67%
So the percent markup is 67%.

the edge of a cube is increasing a tthe uniform rate of .2 inches per second. at the instant when the total surface area becomes 150 square inches, what is the rate of increase, in cubic inches per second, of the volume of the cube.
The rate of increase of the volume of the cube is 0.8 cubic inches per second.
Let x denote the edge of the cube at any given instant.
The total surface area of the cube
= 6x^2
The given condition is: 6x^2 = 150
=> x^2 = 25
=> x = 5
Now, the rate of increase of the edge of the cube is 0.2 inches/second.
Therefore, the rate of increase of the volume of the cube = rate of increase of the edge * rate of increase of the edge * rate of increase of the edge
=> 0.2 * 0.2 * 0.2
= 0.008 inches^3/second
= 0.8 cubic inches/second
The rate of increase of the volume of the cube is 0.8 cubic inches per second, which is calculated by multiplying the rate of increase of the edge (0.2 inches/second) three times.

A line passes through points (3,14) and (9,20). Write a linear function rule in terms of x and y for this line.
Answer:
y = x + 11
Step-by-step explanation:
the equation of a straight line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 14 ) and (x₂, y₂ ) = (9, 20 )
m = [tex]\frac{20-14}{9-3}[/tex] = [tex]\frac{6}{6}[/tex] = 1 , then
y = x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (3, 14 )
14 = 3 + c ⇒ c = 14 - 3 = 11
y = x + 11 ← equation of line
A line passes through points (3,14) and (9,20), linear function rule in terms of x and y for this line is y = x + 11
A linear function in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the point values from the problem, we get:m = (20 - 14) / (9 - 3) = 6/6 = 1
The y-intercept be found by plugging in any one of the point values and the slope into the equation y = mx + b and solving for b. Using the point (3,14), we get:
14 = 1*3 + b
b = 11So the linear function in terms of x and y is:
y = x + 11
A linear function is a type of mathematical function that, when graphed, defines a straight line. It is defined by the equation y = mx + b, where x and y are variables, m is the line's slope, and b is the y-intercept (the point where the line crosses the y-axis). The slope (m) of the line represents its steepness, and the y-intercept (b) represents the point at which the line intersects the y-axis.

Answer:
2x^2 + x + 9 + (18/(x+2))
Step-by-step explanation:
To find the result when 2x^3 - 5x^2 - 9x + 18 is divided by x + 2 using the long division method, you can follow these steps:
Divide the first term of the dividend (2x^3) by the first term of the divisor (x). The result is 2x^2.
Multiply the divisor (x + 2) by 2x^2. The result is 2x^3 + 4x^2.
Subtract this result from the dividend (2x^3 - 5x^2 - 9x + 18). The result is -x^2 - 9x + 18
Bring down the next term of the dividend (-5x^2) and add it to the result from step 3. The result is -6x^2 - 9x + 18
Divide -6x^2 by -6x and the result is x.
Multiply the divisor by x. The result is x^2 + 2x
Subtract this result from the result of step 4. The result is -9x + 18
Bring down the next term of the dividend (-9x) and add it to the result from step 7. The result is -18x + 18
Divide -18x by -18 and the result is x
Multiply the divisor by x. The result is x^2 + 2x
Subtract this result from the result of step 8. The result is 18
Therefore, the quotient is 2x^2 + x + 9 and the remainder is 18
So the result when 2x^3 - 5x^2 - 9x + 18 is divided by x + 2 is 2x^2 + x + 9 + (18/(x+2))

The average speed so far is 226.4 miles per hour.
Time taken: 3 hours 49 minutes + 6 hours 27 minutes
= 10 hours 16 minutes
Total distance: 163 miles + 411 miles
= 574 miles
Average speed: 574 miles / (10 hours 16 minutes)
= 226.4 miles per hour
To calculate the average speed of the Copeland family's trip so far, we need to know the total distance they have traveled and the total time they have spent traveling. We can calculate this by adding the distance driven by Mr. Copeland (163 miles) and the distance driven by Mrs. Copeland (411 miles) to get a total distance of 574 miles. Then, we can add the time taken by Mr. Copeland (3 hours 49 minutes) and the time taken by Mrs. Copeland (6 hours 27 minutes) to get a total time of 10 hours 16 minutes. We can then divide the total distance (574 miles) by the total time (10 hours 16 minutes) to get an average speed of 226.4 miles per hour.

Dr. Jimenez found that after applying an antibiotic to bacteria, he observed only 90% of the bacteria left in the culture dish each hour. If the initial bacteria count was 100, what was the bacteria count after 5 hours? Round to the nearest whole number
Step-by-step explanation:
one way of simply calculating this is by using basic percentage calculations.
So because 90% of bacteria was left after every hour, one could use the intial number we were given to find out the next bacteria count. You could work it out by :
in the first hour; 90/100 ×100= 90so in the 1hr the bacteria count was 90.
so you continue working it out for each hr
2nd hr; 90/100×90=81then work it out until u hve calculated for 5hrs, so the answers for each hr will be 90, 81, 72.9, 65.61, 59.049
then add them up and it will give you 368.559 bacteria count. When rounded off it will be 369.
thats how i would hve tackled it
The bacteria count after 5 hours was found to be 59.
For this case we have a function of the form:
y = A × ([tex]b^{x}[/tex]) < br/ >
Where,
A - the initial amount of bacteria
b - decrease rate
x - time in hours
Substituting values we have in the above form, we get:
y = 100 × [tex](0.90)^{x}[/tex] < br/ >
Then after 5 hours we have the equation,
y = 100 × [tex](0.90)^{x}[/tex] < br/ > < br/ > y = 59.049 < br/ >
Rounding to the nearest whole number the equation becomes,
y = 59 < br/ >
Therefore, the bacterium count after 5 hours was found to be 59.

The probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg is 0.0579.
The Central Limit Theorem states that the distribution of the mean of a large sample (n>30) taken from a population with a finite mean and standard deviation will be approximately normal.
Since we are given that systolic blood pressures are normally distributed and we have n = 23>30, we can assume that the mean systolic blood pressure of 23 women will be approximately normally distributed with a mean of 114.8 mm Hg and a standard deviation of 13.1/[tex]\sqrt{23}[/tex] = 2.731 mm Hg.
To find the probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg, we can standardize the problem and use the standard normal distribution table.
We can standardize the problem by finding the number of standard deviations away from the mean of the lower and upper bounds of the range.
z_lower = (119 - 114.8) / 2.731) = 1.537
z_upper = (122 - 114.8) / 2.731) = 2.636
Now we can use the standard normal distribution table to find the probability that a standard normal variable is between z_lower and z_upper.
P(z_lower < Z < z_upper) = P(Z ≤ 2.636) - P(Z < 1.537) = 0.9958 - 0.9379 = 0.0579
Therefore, the probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg is 0.0579.

When solving the inequality, the direction of an inequality is reversed when we multiply or divide both sides by a negative value.The collection of all solutions makes up the solution set for an inequality.
Here,
1. x <-4 and y<-x-7
The graph of this system is attached as a below as Graph 1.
In the graph, red represents x <-4 and green represents y<-x-7.
Possible solution
Putting x=-4 in y=-x-7, we get
y=-(-4)-7
y=-3
So, the solution of the system is (-4,-3).
2. y<-3x-8 and y>5x+8
The graph of this system is attached as a below as Graph 2.
In the graph, red represents y<-3x-8 and green represents y>5x+8.
Possible solution
Putting x=-2 in y=5x+8, we get
y=5(-2)+8
y=-10+8
y=-2
So, the solution of the system is (-2,-2).
Hence, the possible solutions are (-4,-3) and (-2,-2) respectively.
