Answer:
The coordinates of the point on a circle with radius 4 at an angle of radians are x = -2 and y = 3.464.
Step-by-step explanation:
This problem ask us to determine the rectangular coordinates from polar coordinates. The polar coordinates of the point in rectangular form is expressed by the following expression:
Where and are the radius of the circle and the angle of inclination of the point with respect to horizontal, measured in radians. If and , the coordinates of the point are:
The coordinates of the point on a circle with radius 4 at an angle of radians are x = -2 and y = 3.464.
Answer:
z=0
Step-by-step explanation:
1- subtract 7 from both sides
-3z=0
2- divide by -3
z = 0/-3
z=0

The equation of the line in the graph given is: y = -3x - 1.
<h3>How to Write the Equation of a Line?</h3>
Find the slope of the line, which is: m = rise/run.
Rise of the line = 3 units
Run = 1
Slope (m) = -3/1 = -3
Y-intercept (b) = -1 (at this point, x equals zero)
Substitute m = -3 and b = -1 into y = mx + b
y = -3x + (-1)
y = -3x - 1

Answer:
<h2>49</h2>
Step-by-step explanation:
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
==============================================
(-5)² - 2 × (-9) + 6 <em>first </em><em>E</em><em>xponents</em>
25 - 2 × (-9) + 6 <em>next </em><em>M</em><em>ultiplication</em>
25 + 18 + 6 <em>next </em><em>A</em><em>ddition</em>
43 + 6 = 49
