A cubical tank whose edges each measure 12 centimeters is half-filled with water. The water is poured into an empty rectangular tank measuring 10 centimeters by 8 centimeters by 7 centimeters until it is full. How much water is left in the cubical tank? Give your answer in millimeters. ​

Answers

Answer 1

The amount of water left in the cubical tank would be; 3040000 mm³

What is a cube?

A cube is a three-dimensional representation of a square. it has 6 faces 2 on the bottom and top, 4 on the sides faces.

We know that Volume of a cube = a³ ; a = size of edge

Volume of cubical tank = 12³

= 1728 cm³

Now, Half filled cube = 1728 / 2

= 864 cm³

Volume is f rectangular tank :

V = length x width x height

V = 10 * 8 * 7 = 560 cm³

Volume of water left in cubical tank will be;

(864 - 560) = 304cm³

1cm³ = 1000mm³

Therefore,

304cm³ = 304 x 1000 = 3040000mm³

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.

x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36

Answers

Since the center of the circle lies on the y-axis, the x-coordinate of the center must be 0.

Also, since the diameter of the circle is 12 units, the radius is half of that, or 6 units.

Using the standard form of the equation of a circle, which is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius, we can substitute the values we know and simplify the equations to see which ones match.

The equations that represent circles with a diameter of 12 units and a center that lies on the y-axis are:

   x^2 + (y - 6)^2 = 36 (center is at (0, 6))

   x^2 + (y + 6)^2 = 36 (center is at (0, -6))

Therefore, the two options that represent the circles with the given properties are:

x^2 + (y - 6)^2 = 36 and x^2 + (y + 6)^2 = 36.

What does interest actually mean?

To determine simple interest, divide the sum by the cost of borrowing, the amount of time left, and other factors. Principal plus interest plus hours is the straightforward return strategy in marketing. The simplest approach to calculate interest is to use this method. The most popular method of calculating revenue is as a fraction of the principal amount.

Method 1: A basic interest rate of $2.50 per month for a year equals

=> $2.50 x 12 = $30 in interest.

The balance after a year equals $600 plus $30, or $630.

Response: $630

Step 2: Divide the monthly interest rate by 12 to get 0.4167%

Amount after a year:

=> $600 multiplied by (1 + 0.004167)/12 to arrive at $659.15

Response: $659.15

Option 3: $50 per month in deposits

Interest rate per month: 5% divided by 12 Equals 0.4167%

Surplus at the end of the year is equal to

=> $50 x (((1 + 0.004167)12 - 1) / 0.004167) x (1 + 0.004167) = $638.89

write an equation in point slope form of the line that passes through the point (-3 , -1) with slope -1/3

Answers

As a result, the equation in point-slope form for the line passing through the point (-3, -1) with a slope of -1/3 is: y - (-1) = (-1/3)(x - (-3)) or y + 1 = (-1/3)(x + 3)

what is slope ?

Slope is a mathematical term that describes how steep a path is. The ratio of the vertical shift (rise) to the horizontal transition (run) between any two points on a line is more precisely known as the slope of a line. A line's inclination can be zero, positive, negative, or undefinable. A line that has a positive slope is rising as it travels from left to right, whereas a line that has a negative slope is falling as it moves in the opposite direction. A line has a slope of zero if it is straight, and a slope of infinity if it is vertical.

given

The linear equation's point-slope form is:

y - y1 = m(x - x1) (x - x1)

where (x1, y1) is a spot on the line and m denotes the angle of the line's slope. The equation of the line can be expressed as follows using the provided point (-3, -1) and slope of -1/3:

y - (-1) = (-1/3)(x - (-3))

Streamlining the right side:

y + 1 = (-1/3)(x + 3)

Increasing the right side:

y + 1 = (-1/3)x - 1

Taking away 1 from both sides:

y = (-1/3)x - 2

As a result, the equation in point-slope form for the line passing through the point (-3, -1) with a slope of -1/3 is: y - (-1) = (-1/3)(x - (-3)) or y + 1 = (-1/3)(x + 3)

F(-10) = 20201F(2) = 17F(3) = 142

What is Function?

Function is the relationship between inputs where each input is related to exactly one output. It is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output, and the output can be traced back to its input.

"y is a function of x" (denoted y = f(x)) means that y varies according to whatever value x takes on.

How to determine

Where F(x) = 2x^4 + x^2 - 10x + 1

So, to calculate f(-10)

f(x) = y

Where x = -10

f(-10) = 2(-10)^4 + (-10)^2 -10(-10) + 1

f(-10) = 2(10000) + 100 + 100 + 1

f(-10) = 20000 + 100 + 100 + 1

f(-10) = 20201

For f(2),

f(x) = y

Where x = 2

f(2) = 2(2)^4 +2^2 -10(2) + 1

f(2) = 2(16) + 4 -20 + 1

f(2) = 32 + 4 -20 + 1

f(2) = 17

For f(3)

f(x) = y

Where x = 3

f(3) = 2(3)^4 + 3^2 -10(3) + 1

f(3) = 2(81) + 9 -30 + 1

f(3) = 162 + 9 - 30 + 1

Therefore , the solution of the given problem of equation comes out to be  y = 6x + 11.

How do equations work?

Mathematical formulas frequently use the same letter to try to impose uniformity between two claims. Many variable academic numbers are shown to be equal using mathematical equations, also known as assertions. The normalise divides 12 and b + 6 into two parts using the result y + 6 = 12 as an illustration. It is possible to determine the connection between each sign component and the number of lines. The significance of a symbol usually contradicts itself.

Here,

In slope-intercept form, the provided equation y = -1/6x - 2 has a slope of -1/6. Consequently, this line's perpendicular inclination is as follows:

=> m2 = -(1/-1/6) = 6

Now that we know the desired line's slope and the spot through which it passes (-2, -1). To determine the solution of a linear equation, we can use its point-slope form:

=> y - y1 = m(x - x1) (x - x1)

where m is the slope 6 and (x1, y1) is the position (-2, -1). By replacing these numbers, we obtain:

=> y + 1 = 6(x + 2) y + 1

=> 6x + 12 y + 1

=> 6x + 11 y - (-1)

=> 6(x - (-2))

As a result, the equation for the line passing through the position (-2, -1) and perpendicular to y = -1/6x - 2 is y = 6x + 11.

The principal P is borrowed at a simple interest rate r for a period of time t. Find the​ loan's future value​ A, or the total amount due at time t.
P=​$1000​, r=5.0​%, t=6 months

Answers

Step-by-step explanation:

To calculate the future value of a loan with simple interest, we can use the formula:

A = P(1 + rt)

where A is the future value or total amount due, P is the principal, r is the interest rate, and t is the time period in years.

In this case, we have:

P = $1000

r = 5.0% = 0.05 (expressed as a decimal)

t = 6 months = 0.5 years (since there are 12 months in a year)

Plugging these values into the formula, we get:

A = $1000(1 + 0.05 x 0.5)

A = $1000(1.025)

A = $1025

Therefore, the future value or total amount due on the loan after 6 months is $1025.

Answers

The function g(x) = 3/(x-2) + 5 is a transformation of the parent function f(x) = 1/x with a horizontal shift of 2 units to the right, a vertical stretch by a factor of 3, and a vertical shift of 5 units up.

What is the transformation of the function

The function g(x) = 3/(x-2) + 5 is a transformation of the parent function f(x) = 1/x.

Here are the transformations that were applied to f(x) to obtain g(x):

1. Horizontal shift: The denominator of f(x) is x, which means that the vertical asymptote is at x = 0. By subtracting 2 from x in the denominator of g(x), we are shifting the vertical asymptote to x = 2. This is a horizontal shift of 2 units to the right.

2. Vertical stretch: The coefficient 3 in front of the fraction means that the function is stretched vertically by a factor of 3 compared to f(x). This means that the distance between the horizontal asymptotes (which are at y = 0 for f(x) and y = 5 for g(x)) is three times larger for g(x) than for f(x).

3. Vertical shift: The constant 5 added to the fraction means that the entire function is shifted vertically by 5 units compared to f(x). This means that the horizontal asymptote of g(x) is at y = 5 instead of y = 0.

The solution of the given equation -4(n+5)=-32 is n=3.

What is equations ?

An equation is a mathematical statement that shows that two expressions are equal. It contains an equals sign (=) between two expressions. The expressions on both sides of the equals sign have the same value. Equations are used to solve problems in mathematics and science.

To solve the equation, we need to isolate the variable n.

-4(n+5) = -32

Distribute -4 on the left side of the equation:

-4n - 20 = -32

Add 20 to both sides of the equation:

-4n = -12

Divide both sides by -4:

n = 3

Therefore, the solution of the given equation -4(n+5)=-32 is n=3.

Step-by-step explanation:

Calculate the cash discount and the net amount due the transaction (in $).

Answers

The cash discount is $353.20 and the net amount due is $17,306.80.

What are the purchase terms?

Conditions of sale are the rules that govern a business transaction, including the cost, the method of payment, the delivery, and any other pertinent information. Normally, they are specified in a sales contract or invoice and acknowledged in advance of the transaction. The conditions of sale might alter based on the type of products or services being exchanged, the volume and complexity of the deal, and other elements.

We know that,

Cash discount = amount x discount rate

Net amount due = amount - cash discount

For 2/10:

Cash discount = $17,660 x 2% = $353.20

Net amount due = $17,660 - $353.20 = $17,306.80

Hence, the cash discount is $353.20 and the net amount due is $17,306.80.

A radioactive element has a half-life of 34 years. How long will it take for 21% of a sample to remain after decay begins? Round your answer to the nearest year.

Answers

The number of years for 21% to remain is 78years

What is half life?

The time required for half of the original population of radioactive atoms to decay is called the half-life.

half life = 0.693/decay constant

decay constant = 0.693/34

= 0.02

21% of N(o) = 21N(o)/100 = N(y)

from the formula

N(t) = Noe^-kt

21N(o)/100 = Noe^-kt

21N(o)=100 Noe^-kt

divide bother sides by N(o)

21 = 100e^-kt

e^-kt = 21/100

e^-kt = 0.21

-0.02 t= ln0.21

-0.02 t= -1.56t

t = 1.56/0.02
