.5 * -10 or 5 * -20 shows it written in scientific notation
Wavelength, period and frequency are closely related to each other. By definition, wavelength is just the distance between two identical points in the adjacent cycles of a wave, and period is the time it takes to complete one cycle of the wave. Frequency is then the number of cycles in a second. Hope this helps
Answer: 90° or 75°
Step-by-step explanation:
the angle looks like a right angle and a right angle is 90°
y=8(x^2 + 4x + 4) +17 + -32
Simplify:
y = 8(x^2 + 4x + 4) + 15
Use distributive property:
y = 8x^2 + 32x +32 - 15
Simplify:
y = 8x^2 + 32x +17
Complete the square using form ax^2+bx+c:
a = 8, b = 32, c = 17
vertex form = a(x+d)^2+e
d = b/2a and e = c-b^2/4a
d = 32/2*8 = 32/16 = 2
e = 17 - 32^2/4*8 = 17-1024/32 = 17-32 = -15
Vertex form = y = 8(x+2)^2 + -15
