Answer:

D. 3.8 ft

Step-by-step explanation:

circumference = 2π * 30.14

arc length = 2π*30.14 * (π/25) / 2π = 60.28π/50 = 3.7875 ≈ 3.8

Answer:

a=21.2

n=√29

Step-by-step explanation:

$90+68.2+a=180$

$a+158.2=180$

$a=21.2$

$2^2+5^2=n^2$

$4+25=n^2$

$n^2=29$

$n=\sqrt{29}$

Cotθ= tan30° find theta

scoundrel [369]

Answer:

60

Step-by-step explanation:

Cot is the same as 1/tan so:

$1/tan(theta) = tan(30)$

By rearranging the equation, we get:

$1/tan(30) = tan(theta)$

By taking the inverse tan, we get:

$theta = tan^-1 (1/tan(30)) =60$

Answer:

y = -3x + 1

Step-by-step explanation:

y = -3x + 1

y = -3 . -2 + 1

= 6 + 1

y = 7

y = -3x + 1

y = -3 . 2 + 1

= -6 + 1

= -5

y = -3x + 1

= -3 . 4 + 1

= -12 + 1

= -11

so, it should be y = -3x + 1
