Ghella [55]3 years ago
5 0

Answer:

Step-by-step explanation:

f(n)=64+6n

f(n-1)=64+6(n-1)=64+6n-6=f(n)-6

f(n-1)+6=f(n)

or f(n)-f(n-1)=6

The coordinates of the endpoints of directed line sergeant ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2 then the coordinates of
cestrela7 [59]

The correct answer is A) (1,-5)

Further explanation:

Given points are:

A(-8,7)=(x1,y1)

C(7,13)=(x2,y2)

IT is also given that

AB:BC=3:2

Which means that B divides the line segment in 3:2

Here,

m=3

n=2

To find the coordinates of B

x_B=\frac{mx_2+nx_1}{m+n}\\ = \frac{(3)(7)+(2)(-8)}{3+2}\\=\frac{21-16}{5}\\=\frac{5}{5}\\=1\\y_B=\frac{my_2+ny_1}{m+n}\\=\frac{(3)(-13)+(2)(7)}{3+2}\\=\frac{-39+14}{5}\\=\frac{-25}{5}\\=-5

The coordinates of point B are (1,-5)

The correct answer is A) (1,-5)

How would you convince a fellow student that the number 0.57 is a rational number? (5+ sentences please) Please help me with thi
Gre4nikov [31]

Answer:  0.57 = 57/100 this means it has to be rational.

Explanation: You have to explain to them that any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. An integer can be written as a fraction simply by giving it a denominator of one, so any integer is a rational number.

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?
jekas [21]

The sum of the interior angles in the polygon whose side is 10 is 1440^{0}

<h3>What is sum of interior angle of polygon ?</h3>

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.

As, The formula for calculating the sum of interior angles is ( n − 2 ) × 180^{0}

S0, n=10

Then, sum of interior angle be = (n-2) x 180

                                                   = (10-2) x 180

                                                   = 8 x 180

                                                   = 1440^{0}

Thus, the sum of the interior angles in the polygon is 1440^{0}

Answer:

There are 327,811 doctors.

Step-by-step explanation:

Percentage of female doctors = 16.9%

Number of female doctors = 55,400

Percentage of Male doctors = 100-16.9%

                                               =83.1%

So if 55,400 doctors are represented by 16.9 how many doctors are represented by 100%?

100% represents total number of doctors.

⇒\frac{55,400}{16.9} \times100

=327,810.65

Number of doctors has to be a whole number so we rounf off the number to nearest whole number:

Therefore there are 327,811 doctors.
