In a recent year, 23.9% of all registered doctors were female. If there were 47,400 female registered doctors that year, what was the total number of registered doctors?
Round your answer to the nearest whole number.

Answer:

The exponential equation is;

F = 30,000(1.01)^30

The value is;

$40,435.50

Step-by-step explanation:

Here, we are to write an exponential equation

Exponential equations generally take the form;

F = I(1 + r)^t

where F is the future value

I is the initial value

r is the growth percentage

t is the time

with respect to the question;

F = ?

I = 3,000

t = 30

r = 10% = 10/100 = 0.1

Writing the equation, we have

F = 30,000(1.+ 0.1)^30

F = 30,000(1.01)^30

F = $40,435.50

===============================================

Explanation:

We'll use the rule

x^y*x^z = x^(y+z)

This says that when we multiply exponential expressions with the same base, we add the exponents. In this case, the base is 2 so x = 2.

The exponents we're adding are -4 and 2

So,

2^(-4)*2^2 = 2^(-4+2) = 2^(-2)

This matches up with the a^b to show that a = 2 and b = -2

Furthermore, we'll use the rule that x^(-y) = 1/(x^y) to go from 2^(-2) to 1/(2^2) = 1/4 which is the value of c.

Step-by-step explanation:

How you find the circumference is easy.

The formula is 2πr, meaning you multiply 2 times pi (3.14) times the radius (20 m)

2 x 3.14 =

6.28 x 20 =

Circumference: 125.6

The second problem is easier than the last.

Instead of multiplying by 2, you'll only multiply 3.14 (pi) times 90.

3.14 x 90 =

Circumference: 282.6

Answer:

Step-by-step explanation:

Since calculating volume is multiplying the side lengths together we first have:

b x b x 4

Then we can simplify b x b to b ²

And when you multiply b² by 4 you get 4b²

Answer:

Radius, r = 4 units

Step-by-step explanation:

The equation of circle is given by :

[tex]x^2+y^2-10x+6y+18=0[/tex]

We need to find the radius of the circle.

The general equation of a circle is given by :

[tex](x-h)^2+(y-k)^2=r^2[/tex] ....(1)

We can rearrange the above equation in terms of the given equation as follows :

[tex]x^2+y^2-10x+6y+18-25-9+25+9=0\\\\(x^2-10x+25)+(y^2+6y+9)+18-25-9=0\\\\(x-5)^2+(y-(-3))^2=(4)^2[/tex]

On comparing the above equation with equation (1)

h = 5, k = -3 and r = 4

So, the radius of the circle is 4 units.

The circumference of the circle is 18π meters.

The distance along a circle's perimeter is referred to as its circumference.

The circumference of a circle can be found by the formula: C = πd, where d is the diameter of the circle.

Given that the diameter of the circle is 18m, we can find its circumference by:

C = πd

C = π18

C = 18π

Therefore, the circumference of the circle is 18π meters.
