Answer:

<em>Length of arc: 6π</em>

Step-by-step explanation:

<em>~ Let us answer this question in terms of π, remaining so ~</em>

1. Assume that this is a complete circle, for the moment being. The chord with length of 12 units would act as the diameter, and using that information we could determine the circumference of this complete circle...which will help us in the future. Apply the formula π * d as such: π * 12 ⇒ 12π to get the circumference as 12π.

2. Knowing that the length of the complete circle's circumference is 12π, this arc is part of a semicircle, meaning that it's value would be half of that of the complete circle's circumference, or in other words: 12π/2 ⇒ <em>Answer ~ Length of arc: 6π</em>

60 degrees in radius
jekas [21]
To convert to radians, multiply the number of degrees by π/180°.
60 * \frac{ \pi }{180}  \\  \frac{60 \pi }{180}  \\  \frac{ \pi }{3}

60° in radians is π/3.

Hope this helps!

You are watering a garden. The height h (in feet) of water spraying from the garden hose can be modeled by h(x)=−0.1x2+0.7x+3, w
swat32

Answer:

g(x) = -0.1x^2 + 0.5x + 3.6

Step-by-step explanation:

Given

h(x) = -0.1x^2 + 0.7x  + 3

Required

Determine the new function

From the question, we understand that the new function wants the water to hit the ground 1 ft farther.

1 ft farther implies x + 1

So, in the given function, we substitute x + 1 for x in h(x) = -0.1x^2 + 0.7x  + 3

This gives:

h(x + 1) = -0.1(x + 1)^2 + 0.7(x + 1)  + 3

Expand Bracket

h(x + 1) = -0.1(x + 1)(x + 1) + 0.7(x + 1)  + 3

h(x + 1) = -0.1(x^2+2x+1) + 0.7(x + 1)  + 3

h(x + 1) = -0.1x^2-0.2x-0.1 + 0.7x + 0.7  + 3

Collect Like Terms

h(x + 1) = -0.1x^2-0.2x + 0.7x + 0.7  + 3-0.1

h(x + 1) = -0.1x^2 + 0.5x + 3.6

Hence, the new function is:

g(x) = h(x + 1) = -0.1x^2 + 0.5x + 3.6

g(x) = -0.1x^2 + 0.5x + 3.6
