Answer:

YES!

Step-by-step explanation:

ratios are like fractions, and fractions are basically division problems. SO, if you divide 4 by 6 you get .66666666, and if you divide 8 by 12 you ALSO get .66666666, soooooo yes they are equivalent!

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 solution of the equation for x is x = 4y - 12

Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function

The function y is given as

y = 1/4x + 3

As a general rule, we start by writing y as a variable (say y = f(x)).

So, the equation of the function becomes

y = 1/4x + 3

The next step is to switch/swap the positions of x and y in the above equation y = 1/4x + 3 (in this case, it is not necessary)

So, the equation remains the same

y = 1/4x + 3

The next step is to make x the subject of the formula in the above equation y = 1/4x + 3

The equation becomes

1/4x = y - 3

This is done by subtracting 3 from both sides of the equation.

So, we have:

1/4x = y - 3

Multiply through the sides of the equation by 4

So, we have

x = 4y - 12

Express as an inverse function

f-1(x) = 4x - 12 --- this is not  compulsory

So, the solution of the equation for x is x = 4y - 12

Hence, the rewuired solution of the equation for x is x = 4y - 12

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:

1211/29 = 41.76 gallons.

Hence the cost is:

41.76 x 3.10 = $129.46.

With the estimate, the number of gallons used is:

1200/30 = 40 gallons.

Hence the cost is:

40 x 3 = $120.

For the estimation, the mileage was rounded up while the cost was rounded down, hence the estimated cost is less than the actual cost.

Answer:

it's 88

Step-by-step explanation:

a century = 100

The cost per passenger for no wind conditions is $199 and 33 cents

Ground speed, 'x' = 500 ± 0 = 500 miles/h;

Cost per passenger is given by;

C(x) = 100 + x/15 + 33000/x;

Put x = 500;

C(500 miles/h) = 100 + 500/15 + 33000/500

C(500 miles/h) = $199.33

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

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 number of tracks on 4 CDs are 132.

Here, we are given that a CD holds 2t + 3 tracks.

Thus, the number tracks on 4 CDs will be given as-

4(2t + 3)

Simplifying the expression further, we get

(4 × 2 × t) + (3 x 4)

= 8t + 12

Therefore, the expression for the number of tracks on 4 CDs is 8t + 12

Now, if t = 15

Then, the number of tracks on 4 CDs can be found by substituting the value t = 15 in the expression (8t + 12)

= 8(15) + 12

= 120 + 12

= 132

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.

Multiplying a complex number by a real number is a scalar of a complex number. The quadrant location of the complex number and its product with the real number are the same.

In this problem we have a paragraph, in which we must fill the blanks with the results of operations with complex numbers. The modulus of a complex number is found by using the Pythagorean theorem:

r = √[(- 2)² + 8²]

r = √(4 + 64)

r = √68

r = 2√17

And the product between the real number and the complex number is done by distributive property:

5 · (- 2 + i 8)

5 · (- 2) + i (5 · 8)

- 10 + i 40, whose modulus is 10√17.
