5. If position of object x = 3 sinΘ – 7 cosΘ then motion of object is bounded between position.​

Answer:

  ±√58 ≈ ±7.616

Step-by-step explanation:

The linear combination of sine and cosine functions will have an amplitude that is the root of the sum of the squares of the individual amplitudes.

  |x| = √(3² +7²) = √58

The motion is bounded between positions ±√58.

_____

Here's a way to get to the relation used above.

The sine of the sum of angles is given by ...

  sin(θ+c) = sin(θ)cos(c) +cos(θ)sin(c)

If this is multiplied by some amplitude A, then we have ...

  A·sin(θ+c) = A·sin(θ)cos(c) +A·cos(θ)sin(c)

Comparing this to the given expression, we find ...

  A·cos(c) = 3   and   A·sin(c) = -7

We know that sin²+cos² = 1, so the sum of the squares of these values is ...

  (A·cos(c))² +(A·sin(c))² = A²(cos(c)² +sin(c)²) = A²(1) = A²

That is, A² = (3)² +(-7)² = 9+49 = 58. This tells us the position function can be written as ...

  x = A·sin(θ +c) . . . . for some angle c

  x = (√58)sin(θ +c)

This has the bounds ±√58.

Write an algebraic expression for each word phrase.
11Alexandr11 [23.1K]

Answer:

63/h - 3.14

Step-by-step explanation:

Quotient means divide.

So the answer to the division is a quotient. 63/h is the quotient of the division.

Less means subtract so the subtraction that is taking place is

63/h - 3.14 and that's your answer.

Often with these questions, you start backwards as in this question.

Brums [2.3K]

Answer:

LCM of 42 and 63 is 126.

Step-by-step explanation:

Find the prime factorization of 42

42 = 2 × 3 × 7Find the prime factorization of 63

63 = 3 × 3 × 7Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 3 × 3 × 7LCM = 126

Alenkinab [10]
2x + x = 180
This is because 2x is on one side while x is on the other, if those two angles add up they must add up to 180 because the two angles form a 180 degree angle or just a straight line
2x + x = 180
3x = 180
x = 60
