Answer:
D. People said that man could not fly, but in 1903, Orville and Wilbur Wright made the first sustained powered flight in a heavier-than-air machine.
Step-by-step explanation:
Answer:
y > 2x + 1
Step-by-step explanation:
The equation of a straight line is
y = mx + b
Your graph looks like the diagram below.
Calculate the slope of the line:
That eliminates Options B and D.
The y intercept is at y = 1.
That eliminates Option A.
The only inequality that fits is
y > 2x + 1
Answer:
( 6, pi/6)
Step-by-step explanation:
( 3 sqrt(3), 3)
To get r we use x^2 + y ^2 = r^2
( 3 sqrt(3) )^2 + 3^2 = r^2
9 *3 +9 = r^2
27+9 = r^2
36 = r^2
Taking the square root of each side
sqrt(36) = sqrt(r^2)
6 =r
Now we need to find theta
tan theta = y/x
tan theta = 3 / 3 sqrt(3)
tan theta = 1/ sqrt(3)
Taking the inverse tan of each side
tan ^-1 ( tan theta) = tan ^ -1 ( 1/ sqrt(3))
theta = pi /6
100 to 49. Because area is units squared, and it is finding by multiplying the side lengths, you would simply square the ratio.
Answer:
-31
Step-by-step explanation:
(2×x) - (2×5) = (3×x) + (3×7)
2x-10 = 3x+21
2x-3x = 21+10
-x = 31
therefore, x = -31
