The equation of the line passing through the points (-3,-15/2) and(1,-3/2) is  3x - 2y - 6 = 0.

What is the equation of a line?

An algebraic way to represent a collection of points that together make a line in a coordinate system is called the equation of a line. An algebraic equation, commonly known as the equation of a line, can be created using the various points that together make up a line in the coordinate axis as a collection of variables (x, y). It is possible to determine whether a specific point lies on a line by utilising the equation of a line.

The equation of a line passing through two points [tex](x_{1} ,y_{1} )[/tex] & [tex](x_{2},y_{2})[/tex] is given by

               [tex]\frac{y-y_{1} }{x-x_{1} } = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Given, two points are  (-3,-15/2) and(1,-3/2).

[tex](x_{1} ,y_{1} )[/tex] = (-3,-15/2) and  [tex](x_{2},y_{2})[/tex] = (1,-3/2).

So, The equation of line passing through (-3,-15/2) and (1,-3/2) is given by

or, [tex]\frac{y+\frac{15}{2} }{x+3 } = \frac{-\frac{3}{2} +\frac{15}{2} }{1 +3 }[/tex]

or, [tex]\frac{y+\frac{15}{2} }{x+3 } = \frac{6}{4 } =\frac{3}{2}[/tex]

or, 2(y+7.5) = 3(x+3)

or, 2y + 15 = 3x + 9

or, 3x - 2y - 6 = 0

Hence, the required equation of the line is 3x - 2y - 6 = 0.

Answer: The value of the account after t years can be found using the formula:

Value = 2900 * (1 + 0.0061/4)^(4t)

The annual growth rate, or APR, is 6.1%. When this rate is compounded quarterly, the effective annual growth rate, or APY, is 6.17%, which is the nearest hundredth of a percent.

Therefore, the function showing the value of the account after t years is:

Value = 2900 * (1 + 0.0061/4)^(4t)

And the annual growth rate, or APY, is 6.17%.

Answer:

x = 2

Step-by-step explanation:

Given equation,

→ 4x - 22 = -14

Now the value of x will be,

→ 4x - 22 = -14

→ 4x = -14 + 22

→ 4x = 8

→ x = 8/4

→ [ x = 2 ]

Hence, the value of x is 2.

The probability that an individual will take far longer than 21 days to complete it is 0.12.

In the descriptive analysis, the standard deviation is the amount of scatter or dispersal of the pieces of data in relation to their mean. It provides information on the distribution of values within the sample data and serves as a gauge for how widely apart the measured values are from the mean.

As per the information available in the question,

Meantime, μ = 14 days

Standard deviation, ρ = 6 days

Assume the time to pass the kidney stone be x.

The probability that it will take someone more time than 21 days to complete it.

Let's find out the Z-score first,

Z-score = (x - μ)/ρ

Substitute values in above equation,

= (21 - 14)/6

Z-score = 1.166.

The probability that it will take someone more time than 21 days to complete it :

P(x > Z) = P(x > 1.16) = 0.12

What is sum of angles of a triangle?

A triangle's total angles equal the straight angle (180 degrees, radians, two right angles, or a half-turn) in a Euclidean space. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle.

For a very long period, it was unknown if there were any alternative geometries for which the total is different. During the 19th century, this issue had a particularly significant impact on mathematics. Ultimately, it was determined that the response was correct: in other geometries, this total can be higher or smaller, but it must then depend on the triangle. Its deviation from 180° represents an instance of an angular defect and is a crucial distinction for geometric systems.

From the fig.

we know,

e=37

b= 143 (vertically opposite angle)

143  +  a = 180 (Linear pair)

a =  180 - 143

a  =  37

e = 37

So,  c = 37 (Vertically opposite angle)

c + d + 85 = 180 (Sum of angles on straight line)

37 + d +  85 = 180

d = 180 - 122

d = 58

e + 90 + f = 180 (Sum of all angles of a triangle)

37 + 90 + f = 180

f = 180 - 127

f = 53

g = 48 (if two sides are equal , then the two angles opposite to the equal    

             sides will also be equal.)

48 + 48 + h = 180 (Sum of angles of a triangle)

h = 180 - 96

h = 94

h+ k = 180 (Linear pair)

94 + k = 180

k = 180 - 94

k = 96

d + k + m = 180 (Sum of angles of a triangle)

58 + 96 + m = 180

m = 180 - 154

m = 26

26 + 85 + p = 180 (Sum of angles of a triangle)

p = 180 - 111

p = 69

p + r = 180 (Linear pair)

r = 180 - 69

r = 111

p = s (corresponding angles)

s = 69

Hence all angles are:

a = 37

b = 143

c = 37

d = 58

e = 37

f = 53

g = 48

h = 94

k = 96

Answer:

base = 8

Step-by-step explanation:

In an isosceles triangle, the legs are equal.

P = 28 = 2L + 8

2L + 8 = 28

2L = 20

L = 20/2 = 10 (length of each leg)

P = 2L + b  (sum of the lengths of the 2 legs and the base)

28 = 2(10) + b

b = 28 - 20 = 8

The solution to the matrix equations A and B are X = (-2 0 4) and X = (-5 1)

From the question, we have the following parameters that can be used in our computation:

Solving matrix A, we have the following representations

2X=(-4 0 8)

Rewrite the equation properly

So, we have

2X = (-4 0 8)

Divide through the matrix by 2

This gives

X = (-2 0 4)

Solving matrix B, we have the following representations

3 X-(1 7)=(-16 -4)

Rewrite the equation properly

So, we have

3X - (1 7) = (-16 -4)

Add (1 7) to both sides of the equation

This gives

3X = (-15 3)

Divide through the matrix by 3

This gives

X = (-5 1)

Hence, the solutions are X = (-2 0 4) and X = (-5 1)

The absolute difference rounded to three decimal places is 2.674.

What is polynomial?

An expression that consists of variables, constants, and exponents and is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given: f(x) = tan(2x)

Then f(5.4) = tan(2 x 5.4) = tan(10.8) = tan(54/5)

The second degree Taylor polynomial centered at x =  5 is given by,

T2(x) = Σ(n = 0, 2) f^n(5)/5!(x - 5)^n

Now,

f°(x) = f(x) = tan(2x)

f(5) = tan(2 x 5) = tan(10)

f'(x) = d/dx(tan(2x))

f'(x) = 2 sec^2x = 2( 1 + tan^2(x))

f'(5) = 2(1 + tan^2(10))

f"(x) = d/dx[2(1 + tan^2(2x)]

f"(x) = 0 + 2(2tan(2x)(2sec^2(2x))

f"(x) = 8 tan(2x)(1 + tan^2(2x))

f"(5) = 8 tan(10)(1 + tan^2(10)

Then

[tex]T_2(x) = \frac{tan(10)}{0!}(x - 5)^0 + \frac{2 + 2tan^210}{1!}(x - 5)^1 + \frac{8(tan(10)(1+tan^2(10)}{2!}(x - 5)^2 \\T_2(5.4) = tan(10) + 2(1 + tan^2(10)) (5.4 - 9) +4tan(10)(1 + tan^2(10)(5.4 - 5)^2\\T_2(5.4) = \frac{16}{25} tan^310 + \frac{4}{5}tan^2(10) + \frac{41}{25} tan(10) + \frac{4}{5}[/tex]

The absolute difference is,

John's average speed for the whole race would be;  12.8 kilometers per hour

The first part of the race was 14 km long, and he completed it in 1 hour.

Now, formula for speed is;

Speed = distance/time

Thus, John's speed in the first part of the race would be;

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the initial population of the country in 2010 be = 12 million

Let the final population of the country in 2022 = 15 million

Now , let the growth rate be represented as r

And , growth rate r = [ ln( final population - ln (initial population ) / no of years ] x 100
