Step-by-step explanation:
Given that,
Construct a line through P that is perpendicular to the line.
We need to construct a perpendicular line P
Using given data
We draw an arc across the line on each side of the point P.
Now, from each arc on the line, draw another arc on the opposite side of the line from the point P.
The point P to the point where the arcs intersect Q.
Hence, The construct a line through P that is perpendicular to the line.

The pressure on a diver in the water varies directly as the depth. If the pressure is 3.6 Ib/in^2 when the depth is 8ft, what is the pressure when the depth is 30ft.
I give Brainliest! Please show your work
Answer:
13.5 lb/in^2
Step-by-step explanation:
8ft = 3.6 lb
30ft= ?
8ft÷30ft = 3.75
this means 8ft goes into 30ft 3.75 times
3.6lb× 3.75=13.5lb/in^2
you times the pressure of 8ft by 3.75 to find how much pressure there is at 30ft

Which of the following is NOT a function?
Answer:
a x=-3
Step-by-step explanation:
The equation x = 3 represents a vertical line and not a mapping from values of x to values of y. For one thing, it fails the vertical line test for functions at the value x = 3.

Find angle x, and angle y
Answer:
x=40
y=40
Step-by-step explanation:
hlo there!
as the given is 90 ° in fig;
90+50+x= 180°( sum of angle of traingle)
x=180-140
x=40°
as there is alternate angle.
lets suppose the alternate angle of x is z
z=40°
now'
40 + 100+ y=180°( sum of angleof traingle)
y=40°
hope it helps!
3600 divided by 1760?
Answer:

please help me!! Will give Brainly if correct
Answer:
-1
Step-by-step explanation:
Let's take two points on the line- (0,2) and (2,0).
To find the slope:
[tex]m = \frac{y_2 - y_1}{x_2-x_1}\\m = \frac{0 - 2}{2-0}\\m = \frac{-2}{2}\\m = -1[/tex]
The slope is -1.

O A. Zero
B. Negative
C. Positive
D Undefined
Answer:
B
Step-by-step explanation:
going down on the right
Answer:
B
Step-by-step explanation:
Aline with zero slope is a horizontal line parallel to the x- axis
A line with undefined slope is a vertical line parallel to the y- axis
A line sloping upwards from left to right has a positive slope
A line sloping downwards from left to right has a negative slope.
The line shown slopes downwards from left to right and has a negative slope

Rewrite 5/12 and 3/4 so they have a common denominator
Answer:
5/12 = 5/12
3/4 = 9/12
Step-by-step explanation:
The common denominator is 12.
5/12 is already in the common form.
3/4= 3*3 / (4 * 3) = 9/12

What is the range of the function?
Answer:
the is c because the answer
The correct answer is B: {2, 6, 8}.
The set of first components (x-coordinates) in the ordered pairs is the domain of the relation: {-1, 3, 5}.
The set of second components (y-coordinates) is the range of the relation. The range of the given problem is the set of second components (on the right): {2, 6, 8}.
Therefore, the correct value is B: {2, 6, 8}.

(y²)³ = y⁶
Step-by-step explanation:
The power of a power rule is generally shows expressions where a power is being raised by another power. In such expressions, the exponents are multiplied together and the base is kept the same, like:
[tex] \qquad \qquad\boxed{ \sf{ { {(x}^{m}) }^{n} = {x}^{mn} }}[/tex]
In order to write the expression (y²)³ in the form of yⁿ, you may use this rule (power of a power rule) to obtain the answer.
[tex]\qquad \quad \sf{ { {(y}^{2}) }^{3} = {y}^{2(3)} = \pmb {\red{ {y}^{6}}}}[/tex]

4-1.5=2.5hhello everyone ,
i am having some problems solving this question in maths
Arrange 13.25 kg, 14560 g, 13.6 kg, 12000 g in descending order ,
Write the following decimals as fractions. Reduce the fractions to lowest
form.
a) 3.6 b) 12.5
i hope u also consider explaining
thank you all .
Answer:
Descending order:
14560g
13.6kg
13.25kg
12000g
a.) [tex]\frac{18}{5}[/tex]
b.) [tex]\frac{25}{2}[/tex]
Step-by-step explanation:
To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.
If we were to put everything into g:
14560g
13600g
13250g
12000g
See how they are still in the correct order?
If we were to put everything into kg:
14.56kg
13.6kg
13.25kg
12kg
Still in descending order!
___________________
Now to find out how to put the decimals into fractions:
Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)
Following this we get:
36
125
Now divide by the same factor (10), we can't change the value of the number, just the way they look!
[tex]\frac{36}{100}[/tex]
[tex]\frac{125}{10}[/tex]
All that's left is it reduce!
[tex]\frac{18}{5}[/tex]
[tex]\frac{25}{2}[/tex]
And as you can see, we are back to the number I had put in the solution!
