Tricia made a circular mat from a square piece of cloth as shown in the diagram below.
kap26 [50]

The option C) 49 inches is the circumference of the circular mat.

<u>Step-by-step explanation:</u>

  • Tricia made a circular mat from a square piece of cloth.
  • The measure of the side length of the square = 14 inches.
  • The length of the side is same as the diameter of the circle.
  • Therefore, the diameter of the circular mat = 14 inches.

<u>To find radius :</u>

Radius = diameter / 2

⇒ 14/2

⇒ 7 inches.

<u>To find the circumference of the circular mat :</u>

Circumference = 2πr

where,

π has the default value of 3.14

r is the radius of the circular mat.

⇒ 2 × 3.14 × 7

⇒ 44 inches.

∴ The circumference of the circular mat is 44 inches.

Since, it is not given in the option. The option C) 49 inches which is close to 44 inches is the right option.

Can anyone solve part C?​
nlexa [21]

Answer:

y - 7 = 4(x - 35)

Step-by-step explanation:

The fundamental theorem of calculus states that:

\frac{d}{dx} \int\limits^x_a {f(t)} \, dt = f(x).

So using the fundamental theorem of calculus, you can find that h'(x) = f(x).

The question tells you that f(x) is periodic with a period of 8, so f(x) repeats itself every 8 units.

Using this, you can find that the slope of h(x) at x = 35 is the same as the slope of h(x) at x = 3, which is 4.

The slope of h(x) at x = 35 is 4.

Now I have to find the value of h(x) when x = 35. It is the area under f(x) from 0 to 35.

The area underneath f(x) from 0 to 35 is 7. When x = 35, h(x) = 7.

Now use the point-slope formula to write the equation of the tangent line.

The answer is <u>y - 7 = 4(x - 35)</u>
