Find the slope of the line whose equation is 8y = 2x 4.

1 answer:

4 0

- 8y = 2x+4 - y = (2x+4)/8 - y = 2(x+2)/8 - simplifies to (x+2)/4 - which can be rewritten as y = (x/4)+(2/4) - which is also equivalent to y = 0.25x + 0.5 if y = mx+b is your standard equation, m represents slope thus 0.25 (or 1/4) is your slope value

Answer:

$\approx 11.2\:\mathrm{in}$

Step-by-step explanation:

The swing of the tip of pendulum is creating an arc. The question is actually asking for the length of this arc. The length of an arc is given by $2r\pi\cdot \frac{\theta}{360}$ , where $r$ is the radius of the circle and $\theta$ is the angle of the arc.

In this problem, we're given:

$\theta = 40^{\circ},\\r=16$

Substituting given values, we get:

$2\cdot 16\cdot \pi \cdot \frac{40}{360}=32\pi\cdot \frac{1}{9}\approx \boxed{11.2\:\mathrm{in}}$

How do you calculate pi??

Virty [35]

Answer: Use the formula.

Step-by-step explanation: The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.
