If the product of their slopes is -1, these lines are perpendicular to each other.
What is perpendicular ?
The word perpendicular means at right angles and this is because when two lines meet, they form right angles. Perpendicular lines can face in any direction such as up and down, crossways, and side-to-side.
The equation of a straight line that is perpendicular to the line y = x is the line y = −x .
E.g. Take the line y = 2x.
Let's construct a perpendicular to the line y = 2x at the point ( 0,3 )
We can therefore state that for any two perpendicular lines y = mx + c and y = nx + c ,
mn = −1 .
If the product of their slopes is -1, these lines are perpendicular to each other.

If you purchased 450 shares of Apple stock 3 years ago for $112.30 per share and you paid 4%
commission for the purchase. How much was the total purchase cost you?
Answer: $52556.40
Step-by-step explanation:
Price per share = $112.30
Number of shares = 450
Cost of the shares = 450 × $112.30 = $50535
Since there is a 4% commission, the total cost of the purchase will be:
= $50535 + (4% × $50535)
= $50535 + (0.04 × $50535)
= $50535 + $2021.40
= $52556.40
PLEASE HELP MAX POINTS AND BRAINLIEST!!!Find the length of the longest nail that could fit entirely within a cylindrical can of radius 2 inches and height of 6 inches.
Answer:
a 7.2 inch nail
Step-by-step explanation:
using the Pythagorean theorem:
the diagonal distance of a 6" height and a 2" radius (4" diameter) would be:
D² = 6² + 4² = 36 + 16 = 52
D = √52 = 7.21 inches

The length of an arc AB from the given circle with radius 6in is 15.7in
Length of an arcThe formula for calculating the length of an arc is expressed as:
L = r theta
where
r is the radius = 6in
theta is the central angle = 150 degrees = 5/6π rad
Substitute
L = 6(5/6π)
L = 5π
L = 5(3.14)
L = 15.7in
Hence the length of an arc AB from the given circle with radius 6in is 15.7in

Answer:
1) D. 343.17
2) C but not sure
Step-by-step explanation:
1) area of triangle is 1/2* base* height= 1/2*18*24 = 216ft²
area of circle is πr²
area of semicircle is πr²/2
diameter=18
radius= 18/2=9
πr²/2 = (22/7* 9*9) / 2
=127.2 (approx)
total area = 127.2+ 216= 343.2

What is the surface area of the cone? Express your answer in terms of π.
Answer:
surface area of a cone = 132.935πft
Step-by-step explanation:
to find the surface area of a cone
given that
radius = 5ft
height of cone = 21ft
recall that the formulae for finding the surface area of a cone = πr( r + √ h² + r²)
so,
surface area of a cone = πr( r + √ h² + r²)
surface area of a cone = π x 5( 5 + √ 21² + 5²)
surface area of a cone = 5π ( 5 + √ 441 + 25)
surface area of a cone = 5π( 5 + 21.587)
surface area of a cone = 5π (26.587)
surface area of a cone = 132.935πft
