Answer:
Step-by-step explanation:
The base is made of a square that is 2 meters by 2 meters.
Base = 4 m^2
The height of the water is 60 cm
60 cm// 100 cm/meter = 0.6 meters
Volume = Base * height
Base = 4m^2
height = 0.6 m
Volume = 4 * 0.6 = 2.4 m^3
A has a volume of 264 cm3
B has a volume of 891 cm3
A has a height of 8 cm
Work out the height of pot B.
Answer:
27 cm
Step-by-step explanation:
the radious of the pot:
[tex]v=\pi r^{2} h[/tex]
[tex]264=\pi r^{2} (8)[/tex]
[tex]r^{2} =\frac{264}{8\pi }[/tex]
The height of pot B
[tex]891=\pi (\frac{264}{8\pi })h[/tex]
[tex]891=(\frac{264}{8} )h[/tex]
[tex]h=\frac{(891)(8)}{264} =27[/tex]

If y varies directly with x which equation describes x = 72 and y = 36?
Answer:
k = 1/2
Step-by-step explanation:
direct variation equation is y = kx where 'k' is the constant of variation
substitute 36 for 'y' and 72 for 'x' to get:
36 = 72k
solve for 'k' to get:
k = 36/72 or k = 1/2

Solve the equation if 0°≤x≤360°*tan x =√3
Answer: This is a trig relationship from one of our special triangles, the 30-60-90 triangle.
Tan x = the opposite side of angle x divided by the adjacent side of angle x
The tangent is √3 when x = 60° or π/3
However, in this problem the value of the tangent is negative. In which of the four quadrants is the tangent function negative?
This function is negative in the second and fourth quadrants or when x = 120 and 300 degrees (or 2pi/3 and 5pi/3)
***I am assuming that the negative sign should be outside of the square root sign***
solve the following system of equations for all three variables.
-9x-y+2z= -4
-6x+y+5z= 2
-4x+y+5z= 6
Answer:
x=2, z=4, y=-6
Step-by-step explanation:
Add
-9x-y+2z= -4
-6x+y+5z= 2
-9x-6x is -15x
-y+y is 0
2z+5z is 7z
-4+2 is -2
So the equation now looks like this: -15x+7z=-2
Subtract
-6x+y+5z= 2
-4x+y+5z= 6
So the equation will look like this:
-6x+y+5z= 2
-(-4x+y+5z= 6)
-6x+4x is -2x
y-y is 0
5z-5z is 0
2-6 is -4
So the equation now looks like this: -2x=-4
You can find x by dividing -2 on both sides:
x=2
So 2 is x
Now you can substitute x into 2
-15(2)+7z=-2
-30+7z=-2
7z=28
Divide 7 on both sides:
z=4
So now you can substitute z into 4 (For any of the three equation)
-4(2)+y+5(4)=6
-8+y+20=6
20 minus 8 is 12
y+12=6
Subtract 12 on both sides:
y=-6
So the answers are
x=2, z=4, y=-6

n) Using the given information, determine the medal category in which the United States far outperformed its closest competitor. Show your working to justify your answer.
The medal category in which the United States far outperformed its closest competitor is the gold medal category.
In order to determine which medal category the United States far outperformed its closest competitor, we need to determine the difference in the medals gotten by the United States and its closest competitor for each medal category. The medal category with the largest difference is the correct answer.
Gold medal
Medals US got = 1022
Medals the closest competitor had = Soviet Union = 440
Difference = 1022 - 440 = 582 medals.
Silver medals
Medals US got = 794
Medals the closest competitor had = Soviet Union = 357
Difference = 794 - 357 = 437 medals
Bronze medals
Medals US got = 704
Medals the closest competitor had = Germany = 349
Difference = 704 - 349 = 355 medals

I when I'm 10, my brother is half of my age. How old is my brother if I am 44 now
Answer:
Step-by-step explanation:
A-B = 4–2 = 2 (age difference between A and B). IF A = 44,. B = A - 2 = 44 - 2 = 42 years old.
Answer:
39 years old
It could be;
10 ÷ 1/2 = 5
Age difference= 10 - 5= 5 years
So, 44 - 5 = 39 years old
Human population numbers are in constant flux. Suppose a country has a population of 20 million people at the start of one year and during the year there are 600,000 births, 350,000 deaths, 100,000 immigrants, and 5,000 emigrants. You and your classmates will determine the total population at the end of the year and then model expected change over a longer period.
According to the question given,
[tex]\sf\longmapsto \: emigrants=-5000[/tex]
[tex]\sf\longmapsto \: Immigrants = 100000[/tex]
[tex]\sf\longmapsto \: Death -350000[/tex]
[tex] \sf \longmapsto \: Birth=600000[/tex]
Now let's solve out and get the result!
The change of population:
[tex] \sf \longmapsto600000-350000 + 100000 - 5000=350000[/tex]
The total population at the end of the year:
[tex]\sf\longmapsto \:2000000 + 350000 [/tex]
[tex]\sf\dashrightarrow2350000[/tex]
Hence the total population at the end of the year is 2350000.At the end of the year, the population will be 20,345,000.
The rate of change in population is 1.75%.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
The given information are,
Total population of the country initially = 20,000,000
Total number of births during the year = 600,000
Total number of deaths during the year = 350,000
Number of immigrants = 100,000
And number of emigrants = 5,000
The population at the end of the year
= 20,000,000 + 600,000 - 350,000 + 100,000 - 5,000
= 20,345,000
At the end of the year the population will be 20,345,000.
The increase in population = 20,345,000 - 20,000,000
= 345,000
the rate of increasing = 345000/20000000)x100 = 1.75%
The rate of change per year is 1.75%.

ANSWER QUICKLY!!!!!
Given the polynomial function
f(x)=x3−4x2+x+6
1) Name all of the possible rational roots for the function using the Rational Root Theorem.
2) Prove 2 is one of the zeroes of this function (show or describe your process).
3) Name all of the actual roots of this function and describe how you found them.
4) Write the original polynomial function f(x)=x3−4x2+x+6 in factored form.
Answer:
1. The possible roots are ±1, ±2, ±3, ±6. These are the factors of the trailing constant (6) divided by the factors of the leading coefficient (1). When the leading coefficient is 1, the possible roots are the factors of the constant
2. The polynomial is easier to evaluate when it is written in Horner form:
f(x) = ((x -4)x +1)x +6
To show that 2 is a zero, we want to find f(2):
f(2) = ((2 -4)2 +1)2 +6 = (-4 +1)2 +6 = -6 +6 = 0
f(2) = 0, so 2 is one of the zeros of this function
3. Using synthetic division (attached) or polynomial long division, we can divide the given polynomial by (x-2) to find the remaining factors. This division gives (x^2 -2x -3), which can be factored as (x -3)(x +1), so the three actual roots are ...
x = 2 (from above), x = 3, x = -1 (from our factorization)
4. In factored form, the polynomial can be written ...
f(x) = (x +1)(x -2)(x -3)
The first factor was found from the fact that 2 was given as a zero of the function. For any zero "a", a factor of the polynomial is (x-a).
The remaining factors were found by factoring the quadratic trinomial that resulted from the division of f(x) by x-2. That trinomial is x^2 -2x -3.
There are a number of methods that can be used to factor x^2 -2x -3. Again, the rational root theorem can help. It suggests that ±1 and ±3 are possible roots.
