Answer: False.
Step-by-step explanation:
There does not exist a "quarter circle" as a circle with a radius of 4 units, the only notable circle that does exist is the unit circle, that is the circle where the radius is equal to 1, represented by the equatin x^2 + y^2 = 1
The term "quarter circle" actually does refer to a fourth part of a circle, not to a circle of radius 4.
So the statement is false
Answer:
A) Tan 60° = 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4 unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ =
So, Tan 60° =
=
∴() × ( = h
∴ h = 12 unit
C) Area of this triangle = × Perpendicular × Base
= × h ×
∵ Perpendicular h = 12 unit
So, Area = × 12 ×
Hence Area of triangle = 41.569 unit²
ANSWER
Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
<u>y=3x-9</u>
