Answer:

40 = (184*j) - 208 or 40 = 184j - 208

(a) Amount of water in the first pool (In liters) = (817 + 19x) liters

Amount of water in the second pool (in liters) = 39x liters

(b) An equation to show when the two pools would have the same amount of water is 817 + 19x = 38x.

Given:

For the First Pool :

Initial amount of water in the Pool = 817 liters

Water is being added to the first pool at a rate of 19 liters per minute.

Amount of water added after x minutes = 19x

So, Total amount of water after x minutes = (817 + 19x) liters

For the Second Pool:

It was empty initially.

Water is being added to the second pool at a rate of 38 liters per minute.

Amount of water added after x minutes = 38x

So, Total amount of water after x minutes = 38x liters

Now to determine an equation to show when the two pools would have the same amount of water.

817 + 19x = 38x

38x - 19x = 817

19x = 817

x = 817/19

x = 43 minutes

What is Linear equation?

A linear equation is one in which the variable's highest power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.

linear equation is given by y= mx + c

Let's use the variables x, y and z to represent each of the three numbers.

If the sum of the three numbers is equal to 80, we have our first equation:

The first number is 8 more than the second, so:

The third number is 2 times the second, so:

Using these values of z and x in the first equation, let's solve it for y:

Now, calculating x and z, we have:

Therefore the first number is 26, the second number is 18 and the third number is 36.

Applying the relations given, considering equivalent angles, the trigonometric measures for the angles are given as follows:

The sine of 240º can be written as follows:

sin(240º) = sin(180º + 60º).

Applying the first relation given on the second line, we have that:

sin(180º + 60º) = -sin(60º)

It is known that sin(60º) = sqrt(3)/2, hence the sine of 240º is given as follows:

sin(240º) = -sin(60º) = -sqrt(3)/2.

The cosine of 225º can be written as follows:

cos(225º) = cos(180º + 45º).

Applying the second relation given on the second line, we have that:

cos(180º + 45º) = -cos(45º)

It is known that cos(45º) = sqrt(2)/2, hence:

cos(225º) = -cos(45º) = -sqrt(2)/2.

The tangent of 225º can be written as follows:

tan(225º) = tan (180º + 45º).

Applying the third relation given on the second line, we have that:

tan(180º + 45º) = tan(45º)

It is known that tan(45º) = 1, hence:

tan(225º) = tan(45º) = 1.

The value of composite function (f о g) (-1) will be -1.

What is Composite function?

A composite function is a function that is written inside with another function and composition of functions is done by substituting one function into another function.

Given that;

The value of functions are;

f (x) = - 3x -1

And, g (x) = x² - 1

Now, All values of functions are;

f (x) = - 3x -1

And, g (x) = x² - 1

Composition of functions is calculated as;

Since, (f о g) (x) = f (g(x))

Substitute the value of function f(x) and g(x) in above equation;

(f о g) (x) = f (g(x))

              = f (x² - 1)

              = - 3(x² - 1) - 1

              = -3x² + 3 - 1

              = -3x² + 2

Put x = -1 in above equation we get;

(f о g) (-1) = - 3 (-1)² + 2

              = - 3 + 2

              = -1

So,  (f о g) (-1) = -1

Thus, The value of composite function (f о g) (-1) will be -1.

         x-2/5 = x+6/10

      Multiply by 10 on each side

         2(x - 2) = x + 6

          Distribute

          2x - 4 = x + 6

           Add 4 on each side

           2x= x + 10

           Subtract x

             x = 10

Answer: x=10

Step-by-step explanation:

1/5(x-2)=1/10(x+6)

Distribute and multiply first

(1/5*x) -(1/5*2)=(1/10*x) +(1/10*6)

1/5x-2/5=1/10x+6/10

We do not have the same denominators on both sides. 5 goes into 10 two times so we will multiply everything on the left by 2 to get a common denominator.

2/10x-4/10=1/10x+6/10

Subtract 1/10x from both sides

1/10x-4/10=6/10

Add 4/10 to both sides

1/10x=10/10

1/10x= 1

Multiply both sides by 10/1 (the fraction inverse) to get rid of the fraction.

(10/1)(1/10x) =(1)(10/1)

x= 10

Check work:

1/5(x-2)=1/10(x+6)

Substitute your answer for x

1/5(10-2)=1/10(10+6)

1/5(8)=1/10(16)

8/5=16/10

Simplify 16/10 by dividing by 2

The water pressure on a submerged object is given by P = 64d, then the value d is 10.5 feet.

a. D = P/64 is the solution to the formula's "d" subject.

b. The depth of a submerged object at a pressure of 672 pounds per square foot is 10. 5 feet.

A function can be defined as an expression, law or rule that shows the relationship between two variables.

Given the role as;

P = 64d

Where;

P stands for pressure in pounds per square foot.

The object's depth, d, is expressed in feet.

Now let's center the formula on the variable "d."

Both sides of the equation are divided by the variable "d64-based "'s coefficient. This is carried out so that the variable can stand on its own.

We have.

P/64 = 64d/64

d = P/ 64

If there is pressure, P is equivalent to 672 pounds per square foot.

When the value of the variable is inserted into the formula, we obtain;

d = P/64

Then,

d = 672/64

Discover the quotient.

d = 10. 5 ft.

Therefore,

The water pressure on a submerged object is given by P = 64d, then the value d is 10.5 feet.

a. D = P/64 is the solution to the formula's "d" subject.

b. The depth of a submerged object at a pressure of 672 pounds per square foot is 10. 5 feet.

What is a mathematical expression?

An expression, often known as a mathematical expression, is a limited collection of symbols that have been well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and groupings can all be represented by mathematical representations, which can also be used to indicate the logical syntax's sequence of operations and other features. However, in contemporary mathematics, and particularly in computer algebra, formulae are seen as expressions that, depending on the values supplied to the variables present in the expressions, can be evaluated to true or false.

The given expression can be solved as follows

   (7x10⁻⁶)(7x10⁻⁶)

= (7x7) x (10⁻⁶x10⁻⁶)

= 49 x 10⁻¹²

The function family sketched is exponential function.

From the graph, we can find certain values of the function for certain x-values.

When x = 0, the function has value 1.

When x = 2, the function has value 4

When x = 3, the function has value 8.

When x = 4, the function has value 16

From this we can identify the function as the exponential function, f(x) = eˣ

because e⁰ = 1. i.e., exponential function has value 1 when x = 0 which satisfy the sketch of the function given.

Also the other options given as piecewise function, linear function and quadratic function.

A piecewise function will not have a continuous sketch, but here the sketch of the function is continuous. So it cannot be a piecewise function. A linear function will have the sketch as a straight line, but here it is not. So it is not a linear function. The function values given in the sketch does not satisfy the quadratic function also.

Okay, here we have this:

Considering the provided information, we are going to find the x- and y- intercepts and explain its meaning. So we obtain the following:

Since the x-intercept is the point where the Graph intersects the x-axis (y=0) and the y-intercept is the point where the Graph intersects the y-axis (x=0), we have that:

x-intercept=(300, 0)

y-intercept=(0, 16)

Since the y-axis represents the number of gallons, and the x-axis time, then the y-intercept indicates that when filling the tank it was left with 16 gallons, and the x-intercept indicates that when emptying the tank had traveled 300 miles.

A postulate is an assumption or a claim that is made without providing any supporting evidence. The fundamental claims that are used to support other claims known as theorems are known as postulates. Once a theorem is established, it can be applied to the establishment of other theorems.

By examining each postulate, we may effectively respond to this query.
