Find the value of M3 - M1

Answers

Answer:

Step-by-step explanation:

m<1+m<2+m<3 = 180 this forms a straight line

m<2 = 90 degrees

m<1 + 90 + m<3 = 180

Subtract 90 from each side

m<1 + 90-90 + m<3 = 180-90

m<1 + m<3 = 90

70 +m<1+m<2 = 180 this forms a straight line

70 + m<1 + 90 = 180

Combine like terms

160 + m<1 = 180

Subtract 160 from each side

160-160 + m<1 = 180-160

m<1 = 20

m<1 + m<3 = 90

20 + m<3 = 90

Subtract 20 from each side

20-20 +m<3=90=20

m<3 = 70

We want to find m<3 - m<1

m<3 - m<1

70 -20

A rectangle has an area of 4x2 +19x + 12 and a length of (x + 4). What is the width?

Answers

The width of the rectangle with an area x² = 19x + 12 is (4x + 3).

What are the area and perimeter of a rectangle?

The area of a rectangle is the product of its length and width.

The perimeter of a rectangle is the sum of the lengths of all the sides.

We know the area of a rectangle is (length×widh).

Given, A rectangle has an area of 4x² + 19x + 12 and a length of (x + 4).

∴ width of the rectangle is = (4x² + 19x + 12)/(x + 4).

Or, we know that the product of two linear equations is a quadratic so,

4x² + 19x + 12.

4x² + 16x + 3x + 12.

4x(x + 4) + 3(x + 4).

(x + 4)(4x + 3).

So, the width of the rectangle is (4x + 3).

The loudness, L , of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d , from the source of the sound. A person 14 feet from a jetski, it is 75 decibels loud.

How loud is the jetski when the person is 45 feet away?

Answers

Answer

7.2593 decibels

Explanation

L ∝ 1/d² Inserting the constant of variation,

L = k/d²

k = Ld²

= 75 × 14²

= 14,700

When d = 45 feet;

L = 14,700/45²

= 14,700/2,025

= 7.2593 decibels

When the person is 45 feet away from the jetski, it is approximately 24.07 decibels loud.

How to determine How loud is the jetski when the person is 45 feet away

We can use the inverse square law to find how loud the jetski is when the person is 45 feet away. The inverse square law states that the loudness ($L$) is inversely proportional to the square of the distance ($d$):

$L = k \cdot (1)/(d^2)$
