A variable in mathematics is a sign and placeholder for any mathematical object (from the Latin variabilis, "changeable"). A variable can specifically represent a number, a vector, a matrix, a function, its argument, a set, or one of its elements.

A variety of issues are resolved by algebraic calculations that treat variables like explicit integers in a single computation. The quadratic formula, for instance, can be used to solve any quadratic equation by exchanging the variables in the quadratic formula for the numerical values of the coefficients in the equation.

Taking into account the scientific notation, the result of the sum is 2.56197×10¹⁹.

Scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

You want to add the following two numbers in scientific notation:

When the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is 19.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 3.197×10¹⁷= 0.03197×10¹⁹

Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:

2.53×10¹⁹ + 0.03197×10¹⁹= (2.53 + 0.03197)×10¹⁹= 2.56197×10¹⁹

Finally, the result of the sum is 2.56197×10¹⁹.

Slope m2=90°

The slope of a line, also known as the gradient is defined as the value of the steepness or the direction of a line in a coordinate plane. Slope can be calculated using different methods, given the equation of a line or the coordinates of points lying on the straight line.

given that, since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel.

so we can conclude since m1=90° the m2 is also = 90°

Answer:

M2 slope = 90°

Step-by-step explanation:

The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on the straight line, slope can be determined using a variety of approaches.

Given that parallel lines must have the same angle from the horizontal and that slope is a measurement of that angle, parallel lines must therefore have the same slope, therefore lines with the same slope are parallel.

We can then deduce that if m1=90°, m2 must also be 90°.

The coordinates of B is (-5, 6).

In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space

What is section formula ?

The section formula helps in determining the coordinates of a point which facilitates division of the line joining two points in a ratio. This takes place either internally or externally.

P (x, y)= (c*m + a*n)/(m + n) , (d*m + b*n)/(m + n ).

Given:

let the coordinates of B (x, y)

M is midpoint M(-6,4) and coordinates of A are (-7, 2)

Using section formula

-6 = (x -7)/2

-12 = x -7

x = -5

and, 4 = y+2/2

8 = y+2

y = 6

Hence, the coordinates of B is (-5, 6)

x = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

[tex]\frac{2}{5x-2}[/tex] = [tex]\frac{3}{6x+1}[/tex] ( cross- multiply )

3(5x - 2) = (2(6x + 1) ← distribute parenthesis on both sides )

The complete proof are;

Suppose m ∠WOX ≠ 90°. By the definition of linear pair of straight line ∠ WOX is supplementary to ∠WOZ.

Therefore,  m ∠WOX + m ∠WOZ = 180°.

By the assumption and the substitution property of equality.

90° + m ∠WOZ = 180°.

Using the subtraction property of equality, the measure of angle WOZ is equal to 90°, which contradicts the given.

Therefore, the assumption is not true and m ∠WOX = 90°.

What are Supplementary angles?

The two angles are called supplementary angles when sum of both angles are 180 degree.

Given that;

m ∠WOZ = 90°

Now, The proof of m ∠WOX = 90° is given as;

Suppose m ∠WOX ≠ 90°.

By the definition of linear pair of straight line ∠ WOX is supplementary to ∠WOZ.

Therefore,  

⇒ m ∠WOX + m ∠WOZ = 180°.

By the assumption and the substitution property of equality.

⇒ 90° + m ∠WOZ = 180°.

Using the subtraction property of equality, the measure of angle WOZ is equal to 90°, which contradicts the given assumption.

Answer:

where is the question bro?

Step-by-step explanation:

Therefore the value of x is 2.

Given 2²ˣ ⁺ ¹ + 2ˣ ⁺ ² = 12 * 2ˣ

2²ˣ ⁺ ¹ + 2ˣ ⁺ ² = 12 * 2ˣ

We can write this as follows

aˣ ⁺ ⁿ = aˣ * aⁿ

2²ˣ * 2 + 2ˣ * 2² = 12 * 2ˣ

2ˣ * 2ˣ * 2 +  2ˣ * 2² = 12 * 2ˣ

By taking common terms aside we get

2ˣ * 2 (2ˣ + 2) = 12 * 2ˣ

By canceling the like terms we get

2ˣ + 2 = 6

2ˣ = 6 - 2

2ˣ = 4

2ˣ = 2²

∴ x = 2

Therefore the value of x is 2.

The length of the radius when the total surface area of a right circular cylinder is 196 cm² is 7√π cm.

It should be noted that the total surface area will be calculated thus,:

= 2πr(h + r)

It was stated that the radius and the.lebgth are the same and that the area is 196. This will be:

2πr(r + r)

= 2πr(2r)

= 4πr²

Therefore, 4πr² = 196

πr² = 198/4

πr² = 49

πr² = 49

r² = 49/π

r = 7√π

Therefore, the length of the radius when the total surface area of a right circular cylinder is 196 cm² is 7√π cm.

Using proportions, it is found that:

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Without the estimate, the number of gallons used is:

1200/30 = 40 gallons.

Hence the cost is:
