Answer:
it would be a graph that went up, down, up, up up
Step-by-step explanation:
Answer:
y = -1/2 is a horizontal line; a line with no slope. With that said, it is linear.
Step-by-step explanation:
Answer:
30.03 degrees
Step-by-step explanation:
You have labeled this diagram correctly.
The trig function that links the side opposite the angle x and the length of the shadow is the tangent function.
Here, tan x = (opposite side) / (adjacent side) = (10 m) / (17.3 m), or 0.578.
Starting from tan x = 0.578, use the inverse tangent function to find the angle, first in radians and then in degrees:
arctan 0.578 = 0.524 radians
Converting this to degrees yields 30.03 degrees. This is the angle of elevation of the sun from the horizontal, from the point where the observer is standing.
Answer:
Given: x²5x - 10 = 0
On comparing the given equation with ax² + bx + c = 0, we get: a = 1, b = -5 and c = -10
For ax²+bx+c = 0, we know that,
-b ± √b² - 4ac 2a X =
[Quadratic
formula]
5± √(-5)² - 4 × 1 × (-10) ... X = 5± √65 2
2 x 1
5 ± 8.06 2
5 +8.06 5-8.06 2 2
13.06 3.06 2 2
Hence, x = 6.53, or x = -1.53.
