PLEASE HELP ME!! WILL GIVE MUCH POINTS!!

Answers

Answer 1

Answer: A is the answer as (-4,8), (2,6), and many others are also possible solutions.

Answer 2

Answer: The correct answer is A, i think because y = 12 and x= 4, 4×3=12, and you can switch any numbers like y = 24 and x = 8, it fits the equation.

What is an equation of the line that is perpendicular to y-3 =-4(x+2)

Answers

Answer:

$y - 3 = (1)/(4)(x+2)$ or choose any line with slope 1/4

Step-by-step explanation:

The slope of this line is -4. The slope of the line perpendicular to this line will be the negative reciprocal or 1/4.

Write the equation using the slope m=1/4 and the point slope form.

$y-y_1=m(x-x_1)\ny-3=(1)/(4)(x+2)$

This is the equation of the line that is perpendicular and passes through the same point (-2,3) as the equation listed.

Answer:

$y=(1)/(4) x+c$ where $c$ can be any number.

Step-by-step explanation:

First we need to clear for y:

$y-3 =-4(x+2)\ny=-4(x+2)+3\ny=-4x-8+3\ny=-4x-5$

and now we have an equation of the form:

$y=mx+b$

where m is the slope and b is the y-intercept.

in this case $m=-4$ and $b=-5$

to find and equation perpendicular to this line, the following must be true: $m*m_(1)=-1$

where m is the slope of the original line that i just mentioned, and $m_(1)$ is the slope of the new line. Substituting $m=-4$

$-4*m_(1)=-1$

clearing for $m_(1)$

$m_(1)=(-1)/(-4) \nm_(1)=(1)/(4)$

thus, the new perpendicular line must have the form:

$y=m_(1)x+c\ny=(1)/(4)x+c$

where the y-intecept $c$ can be any number, some examples are:

$y=(1)/(4)x+3\ny=(1)/(4)x-8$

and so on, the important thing to be a perpendicular line is that the slopes are related to the equation $m*m_(1)=-1$ .

Pipe A can fill a swimming pool in 12 h. Working with another Pipe B, it only takes 3h How long would it take Pipe B working alone to fill the pool

Answers

My guess is 9 hours, because since pipe a takes 12 hours and with pipe b it takes 9, it's 12-9=3 I think.

The area of the polygon is 48 mi2. What is the length of side a? miles

Answers

Answer:

Length of side a = 4.30 miles

Incomplete question:

The area of the regular polygon is 48 mi2. What is the length of side a? miles

Step-by-step explanation:

The number of sides of sides of the polygon is not given, so we will assume the polygon is an hexagon as shown in the attached image;

Given;

Area = 48 mi^2

Area of an hexagon using side a can be written as;

A = (3/2)√3×a^2

Making a the subject of formula

a = √(2/3√3 ×A)

Substituting the values

a = √(2/3√3 ×48)

a = √(32/√3)

a = 4.30 miles

To find the Length of Polygon Sides ('a') of a square polygon with an area of 48 mi², we apply the formula a = √Area. This gives a = √48 miles. This formula applies specifically to squares.

Given the area of the polygon is 48 square miles, to find the length of a side, we would first need to know the type of polygon.

For instance, if it's a square, the area is calculated by squaring one of its sides (Area = side²).

Here, to find the side length ('a'), we take the square root of the area. So, a = √Area.

Applying this to the given area, a = √48 miles.

However, please note that this formula is for a square.

Other polygons have different formulas for calculating such dimensions.
