#4

\\ \sf\longmapsto 8x+1+21x+5=180

\\ \sf\longmapsto 29x+6=180

\\ \sf\longmapsto 29x=174

\\ \sf\longmapsto x=6

#5

\\ \sf\longmapsto x=180-148=32°

And

\\ \sf\longmapsto 90+y=148

\\ \sf\longmapsto y=58°

#6

\\ \sf\longmapsto 4x-25=2x+7

\\ \sf\longmapsto 2x=7+25

\\ \sf\longmapsto 2x=32

\\ \sf\longmapsto x=16

How do you do this question?
r-ruslan [8.4K]

Step-by-step explanation:

y = 3 + 8x^(³/₂), 0 ≤ x ≤ 1

dy/dx = 12√x

Arc length is:

s = ∫ ds

s = ∫₀¹ √(1 + (dy/dx)²) dx

s = ∫₀¹ √(1 + (12√x)²) dx

s = ∫₀¹ √(1 + 144x) dx

If u = 1 + 144x, then du = 144 dx.

s = 1/144 ∫ √u du

s = 1/144 (⅔ u^(³/₂))

s = 1/216 u^(³/₂)

Substitute back:

s = 1/216 (1 + 144x)^(³/₂)

Evaluate between x=0 and x=1.

s = [1/216 (1 + 144)^(³/₂)] − [1/216 (1 + 0)^(³/₂)]

s = 1/216 (145)^(³/₂) − 1/216

s = (145√145 − 1) / 216
