The minimum distance  between the point(-3,2) and the line y = -x + 1  is [tex]\sqrt{2}[/tex] units.

The line that joins  two points on a cartesian plane is a line segment.

Analysis:

The formula for calculating distance between a line and a point is

d = [tex]\frac{Ax1 + By1 + c}{\sqrt{A^{2} + B^{2} } }[/tex]

where A = coefficient of x term of the line, B = coefficient of y in the line and C is the constant term of the line.

x1 and y1 are coordinates of the point.

for the line y = -x + 1 which is  = y + x -1 = 0, A = 1, B = 1, C = -1, x1 = -3, y = 2
d = [tex]\frac{1(-3) + 1(2) + (-1)}{\sqrt{(-3)^{2} + 2^{2} } }[/tex]= [tex]\sqrt{2}[/tex] units

We are asked to find the radius & area of the circle.

To find the [tex]\star\bf{radius}\star[/tex], we divide the diameter by 2:

[tex]\star~\bf{94\div2}[/tex]

[tex]\star~\bf{Radius=47}\star[/tex]

Now that we have the radius, let's compute the area! :)

///\\\///\\\///\\\///\\\///\\\////\\\///\\///\\\///\\\\///\\\///\\\///\\\////\\\///\\\///\\\///\\//\\\//\\

                            Calculating the Area

We can work out the area of a circle by using this formula:

[tex]\star\boxed{\pmb{A_{(circle)}=\pi r^2}}\star[/tex]

Where

[tex]\dag[/tex] A=Area of a circle

[tex]\dag[/tex] [tex]\pi =3.14...[/tex]

[tex]\dag[/tex] r=radius

Have you noticed the [tex]\large\pmb{^2}[/tex] next to r? This tells us that we should multiply the radius times itself.

Now it's time to substitute the values:

[tex]\star~\large\pmb{A=3.14\times47^{2}}\star[/tex]

Let's simplify it. The acronym PEMDAS will help us, and we won't make any mistakes in the Order of Operations! :)

Here's what it stands for:

P=Parentheses

E=Exponents

M=Multiplication

D=Division

A=Addition

S=Subtraction

2 is an exponent.

So what do you think we should do first?

[tex]\square[/tex] Square 47.

[tex]\square[/tex] Multiply 3.14 times 47 and then square.

That's right, we should square 47 first. :)

[tex]\star~\large\pmb{A=\pi \times2209}}\star[/tex]

Now, according to PEMDAS, we should multiply pi times 2209; after multiplying, we obtain:

The correct answer is option A which is the expression will be 0.9S.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that:-

At the end of every month, Katie saves 20 percent of her take-home pay after her taxes. If Katie is taxed at a 25 percent tax rate,

The expression of the salary after six months will be calculated as:-

Let the gross salary is S

The net salary will be = 0.75S

Savings will be = 0.75 x 0.20 S = 0.15S

After six months the savings will be:-

Savings  = 0.15 x 6 S

Savings = 0.9S.

This are interest added on a sum of money invested. Jack will have $168.95 more than Maya in his account

This are interest added on a sum of money invested. The formula for calculating compound amount is given as;

A = P(1 +r/n)^nt

Given the following parameter

P =$2100

rate r = 7 5/8% = 0.07625

time t = 12 years

n =12 (monthly)

Substitute

A = 1200(1+0.07625/12)^12(12)
A = 1200 (2.4895)
A = $2987.46

For Maya

A = 1200(1+0.07375)^12

A = 2818.50

Take the difference

Difference =$2987.46 - $ 2818.5

Answer:

a. $3150

b. $3307.50, $3472.875

c. B(n) = 3000(1.05)^t

Step-by-step explanation:

just a disclaimer i havent done interest in a while so this might not be right

also im assuming this is compound interest

a. P = original amount; r = interest percentage, x = amount of total money

x = P(1 + (r/100)) = 3000(1 + 0.05) = 3150

b. x = 3000(1.05)^2,3 = 3307.5, 3472.875

c. B(n) = P(1+(r/100)^t for t in years. plug in the values to get B(n) = 3000(1.05)^t

Answer:

C. g(x) = sqrt(x+8)-2

Step-by-step explanation:

"Shift two units down" is easier to see in the equation because an up or down shift is just tacked right on to the end of the equation. So "shift DOWN 2" is a minus two on the end of the equation. This means that A and D are both NOT the answer.

Left and right shifts are the opposite of what you might expect. Left shift is a "+ anumber" and Right shift is

"- anumber" This is tucked in very close to the x, because a left or right shift is a change in the x-direction. Again left shift is "+ anumber", so in your question, "shift eight units left" shows in the equation as the plus8 beside the x.

So B is wrong and C is the answer.

The table in which y varies directly with x is table C.

When a variable varies directly with another variable, it means that as one variable increases, the other variable also increases.

The equation that is used to represent direct variation is:

y = kx

Answer:The result follows from manipulating the conditional probability. By definition,

By the law of total probability,

So we have

Step-by-step explanation:

P(A|B) = P(B|A)×P(A)/P(B)

so, in our case

P(A3|B1) = P(B1|A3)×P(A3)/P(B1) = 0.1×0.4/P(B1)

I assume that the problem definition means that A1, A2, A3 are independent and not overlapping events (hence their sum is 1). and therefore, B1 can only happen after A1 or after A2 or after A3. there is no other possibility for B1 to happen.

so,

P(B1) = P(B1|A1) + P(B1|A2) + P(B1|A3) =

= 0.25 + 0.05 + 0.1 = 0.4

therefore,

P(A3|B1) = P(B1|A3)×P(A3)/P(B1) = 0.1×0.4/0.4 = 0.1
