Answer:

Plug the following equation in your calculator and this will be your result

7.247 x 10^6

The value of the exponential equation in scientific notation A = 7.247 x 10⁶

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Let the first number be p = 7.26 x 10⁶

Let the second number be q = 1.3 x 10⁴

Now , the equation is A = p - q

A in the scientific notation is

Substituting the values in the equation , we get

A = 7.26 x 10⁶ - 1.3 x 10⁴

On simplifying the equation , we get

Taking the common factor as 10⁴ , we get

A = 10⁴ ( 7.26 x 10² - 1.3 )

A = 10⁴ ( 726 - 1.3 )

On further simplification , we get

A = 10⁴ ( 724.7 )

And , the value of A in scientific notation is A = 7.247 x 10⁶

Hence , the exponential equation is A = 7.247 x 10⁶

According to the given statement,

The distance between the two points of Traingle A and B is 7.85 m

The area created between two of a triangle's side lengths is known as the angle. Both internal and external angles are present in a triangle. In a triangle, there are three interior angles. When the sides of a triangle are stretched to infinity, exterior angles are created.

Between a triangle's shorter side and its extended side, external angles are created. There is an inside angle next to each outer angle. Angles that share a vertex and side are said to be adjacent.

According to the given value;

Angle B = 60° , Angle A = 50°

In ∆ BCD

tan60° = 30/BC

√3 = 30/BC

BC = 30/√3

BC = 10√3

In ∆ ACD

tan50° = 30/AC

tan50° = 30/(BC+AB)

BC + AB = 30/tan50°

10/√3 + AB = 30/tan50°

AB = 30/tan50° - 10√3

AB = 25.173 - 10√3

AB = 7.85 m

Hence, distance between the two points A and B is 7.85 m.

There are 5040 different ways can the runners finish first, second, third, and fourth place if ten runners are racing.

The permutation is defined as considered an ordered combination.

The general formula for this is:

P(n, r) = n! (n-r)!

Ten runners are racing

There are ten runners who can win first place, hence there are ten ways.

Any of the remaining 9 runners may get up to the second position in nine different ways.

Any of the remaining 8 runners may get up to the third position in eight different ways

Any of the remaining 7 runners may get up to the fourth position in seven different ways

So total number of ways = 10 × 9 × 8 × 7 = 5040

The angle ∠JKN  is 79°

A figure which is formed by two rays or lines that shares a common endpoint is called an angle. A bisector divides an angle into two equal angles.

∠JKN = (8x - 13)°                     (given)

∠NKL = (6x +11)°                      (given)

∠JKN = ∠NKL                         ( As KN bisects ∠JKL )

8x - 3 = 6x + 11                        ( substituting equations from question )

8x - 6x = 11 + 3                        ( bringing like terms on same side)

2x = 23                                    

x = 23/2

x = 11.5

Now, put value of x in the given equation: ∠JKN = (8x - 13). we get

∠JKN = (8x - 13)

D = M/12 + N/4 represents the relationship between Elena's distance in miles, D, and her biking speed.

Speed = distance/ time

Here, we are given that Elena bikes 20 minutes each day for exercise. She bikes at a constant speed of M miles per hour for the first 5 minutes, then at N miles per hour for the last 15 minutes.

Therefore, distance covered by her in the first 5 minutes = speed x time

time = 5 minutes = 5/60 hours

= 1/12 hours

Thus, distance = M(1/12)

= M/12

Now, similarly, distance covered by her in the last 15 minutes = N(15/60)

=N/4

Thus, the total distance in miles, D, covered by her in the last 15 minutes = N(15/60)

= N/4

Thus, the total distance in miles, D, covered by her is D = M/12 + N/4
