Answer:
X=21.21
Step-by-step explanation:
Cos(45)=15\x
0.707=15\x
15\0.707 =x
X= 21.21
Answer:
circular plate
Step-by-step explanation:
Rotational symmetry is attained on a figure if it is possible to achieve the same image of the figure after rotating it. For example , rotating a circular plate marked with numbers 1 to 6 through a 360° rotation, the number marked 1 with attain a position similar like that before rotation.
Answer:
y = 5
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (3, 5)
m = = = 0
This indicates the line is horizontal and parallel to the x0 axis.
The equation of a horizontal line is
y = c
where c is the value of the y- coordinate the line passes through
The line passes through (- 2, 5) and (3, 5) both y- coordinates of 5, thus
y = 5 ← equation of horizontal line
Plug in -2 for x.
f(-2) = 2(-2)^3 - 4(-2)
f(-2) = 2(8) + 8
f(-2) = 16 + 8
f(-2) = 24
