Convert the following radian angle into degrees.

NeTakaya

The degree of the radian angle 0.11 is $6.3^{\circ}$

Explanation:

It is given that the radian angle is 0.11

We need to determine the degrees of the radian angle.

To convert the radian into degrees, let us multiply the radian with $\left(\frac{180}{\pi}\right)$

Thus, we have,

$0.11\times\left(\frac{180}{\pi}\right)=\frac{19.8}{\pi}$

It is given that $\pi=3.14$

Substituting $\pi=3.14$ in the above expression, we have,

$\frac{19.8}{3.14} =6.303...$

Rounding off to the nearest tenth, we have,

$6.3^{\circ}$

Thus, the degree of the radian angle 0.11 is $6.3^{\circ}$

Akiko has a mass of 55kg how much does Akiko weight? Akiko climbs a flight of six steps each 20cm high how much work does she do

Masteriza [31]

Work= forcexdistance
force=55x10(or 9.8 depending on which gravitational field strength you use)
force= 550N
work = 550x0.2
work= 110J
six steps=110x6=660J

Answer:

$f(1) = {(1)}^{3} + 3 {(1)}^{2} - 9(1) + 5 \\ (x - 1) = 0 \rightarrow \: x = 1 \\\frac{{x}^{3 } + {3x}^{2} - 9x + 5}{x - 1} = {x}^{2} + 4x - 5 \\ (x + 5)(x - 1) = 0 \\ x = - 5 \: or \: x = 1 \\ \color{red}\boxed{x_{1} = 1} \\\color{yellow} \boxed {x_{2} = 1} \\ \color{green}\boxed{x_{3} = - 5}$

The answer would be C and F
