Answer: ~27.5
Step-by-step explanation:
I don't know about all the geometry terms, but since a line is 180°, and SE makes 1 right angle (90°), the other side is also 90° (180-90=90).
This means you have a right triangle with sides 15 and 23 and unknown hypotenuse AS.
Pythagorean Theorem: a^2 + b^2 = c^2
(15^2) + (23^2) = AS^2
sqrt( 225 + 529 ) = AS
AS = 27.459
Parallel = same slope
Find slope of 3x + 5y = 8
Turn into y = mx + b
5y = -3x + 8
Divide by 5
y = -3/5x + 8/5
Slope is -3/5
Y = -3/5x + b, find y intercept
Plug in the point
4 = -3/5(10) + b
4 = -6 + b, b = 10
Final equation: y = -3/5x + 10
First you need to find the r, if C=2pieR, than 2.4=2pieR now you divide 2.4 by 2 so you got 1.2=pieR now you divide 1.2 by pie and obtained aproximately 0.38 miles, that is your R, now you do pie multiply by 0.38 exposant 2 and there you go, your answer is aproximately 0.45 miles2 :)
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
Answer:
y=69
Step-by-step explanation:
first step:when y=26 and x=21
c=y-x
c=26-21
c=5
second step: when y is unknown and x=64
To find y we simply add the value of c to x
y=x+c
y=64+5
y=69
