Systems of the Body Constructed Response

Mathematics
1 answer:
fiasKO [112]3 years ago
6 0

Answer:

note: there may be other possible explanations and more body systems can be involved and I can go into much greater detail

1: Nervous system signals your muscles in mouth to abduct and adduct as well as your salivary glands to produce saliva to break down the food, as well as prepare the stomach to digest the food

2: Muscular system moves muscles in mouth to break food down into smaller pieces so there is greater surface area for digestive enzymes to work on the food, then muscles in oesophagus move food to stomach, where stomach muscles churn the broken down food around to speed up digestion

3: Digestive system releases numerous digestive enzymes into the food to break down lipids, carbohydrates and proteins. Small intestines absorb nutrients into bloodstream, and large intestine absorbs water.

4: Excretory system removes excess mostly dry waste through the anus as well as urine from ureter.

What is the perimeter of a square which has the same area as a circle with circumference of 4π?
Contact [7]
The circumference of a circle is given by: 2πr, where r is the radius of the circle. Equating 4π, we have 2πr = 4π so the radius of the circle is: r = 4/2 = 2. Then, the area of the circle is given by πr ^ 2 = π * (2 ^ 2) = 4π.Since the square and the circle have the same area, then: Let L be the side of the square, we have:  L ^ 2 = 4π, clearing L = 2 * (π ^ (1/2))The perimeter of a square is the sum of its sides:  P = L + L + L + L = 2 * (π ^ (1/2)) + 2 * (π ^ (1/2)) + 2 * (π ^ (1/2)) + 2 * (π) ^ (1/2))  P = 8 * (π ^ (1/2))

Vladimir79 [104]

Answer:

choice C: x2 -3x -3

Step-by-step explanation:

(3x^2-7x+2)-(2x^2-4x+5)

becomes

3x^2-7x+2 -2x^2+4x-5

adding

3x^2-2x^2 -7x+4x +2-5

which is

x^2 -3x -3

A force of F pounds is required to pull an object weighing W pounds up a ramp inclined at θ degrees from the horizontal. Find θ
Pie

Answer:

The value of θ is 20.105°

Step-by-step explanation:

Consider the provided information.

A force of F pounds is required to pull an object weighing W pounds up a ramp inclined at θ degrees from the horizontal.

Sine of angle is force over weight.

\sin\theta=\frac{F}{W}

Substitute F = 5500 pounds and W = 16,000 pounds in above formula.

\sin\theta=\frac{5500}{16000}

\sin\theta=\frac{11}{32}

\theta\approx20.105

Hence, the value of θ is 20.105°
