The scale factor of the drawing of the neighborhood park would be = 2000.

The scale factor is defined as the ratio between the scale of the original object and the new object, which represents it but in a different size (larger or smaller).

The width of the neighborhood park. in real life = 8 meters

To convert 8 meters to millimetres is to multiply by 1000

= 8 × 1000 = 8000 mm

The scale factor = 4 × X = 8000

Yes, angle 1 is vertically opposite to angle 4 because they are formed due to the intersection of straight lines.

When two lines intersect each other, then the opposite angles formed are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are equal to each other. Also, a vertically opposite angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees.

For example, if two lines intersect and make an angle, say X=55°, then its opposite angle is also equal to 55°. And the adjacent angle to angle X will be equal to 180 – 55 = 125°

In the given figure, ∠AOC and ∠BOD form a pair of vertically opposite angles and similarly ∠AOD and ∠BOC form such a pair. Therefore,

∠AOC = ∠BOD

The distance of the boat is 191.2 miles, 12.8° and N12.8E from the original location.

To calculate the distance, direction angle, and bearing of the boat from its original location, we will need to use trigonometry to determine the final position of the boat.

a) The distance traveled in the eastward direction is 130 miles. Then, using the bearing of N38E, we can calculate the northward and eastward distances traveled in the second leg of the journey. The bearing of N38E can be thought of as an angle of 38 degrees measured clockwise from due east.

Using trigonometry to calculate the northward distance traveled, we have,

(72 miles) * (sin 38°)

= 36 miles

And the eastward distance traveled is (72 miles) * (cos 38°)

= 59.04 miles.

The final position of the boat is at a distance can be calculated by:

130 miles east + 59.04 miles east

= 189.04 miles east and 36 miles north from the original location.

b) To find the distance from the original location, we use the Pythagorean theorem,

d =  [tex]\sqrt{189.04^{2} +36^{2} }[/tex]

d = 191.2 miles

To find the direction angle, we use arctan(north/east) = arctan(36/189.04) = 12.8°

Bearing is the direction angle measured clockwise from north. So, bearing = 12.8°

Hence, the final position of the boat is 191.2 miles, 12.8°, and N12.8E from the original location.

Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11 gets 3a³ + 4a² - a + 5.

The answer in descending powers of a is 3a³ + 4a² - a + 5.

A polynomial is a mathematical expression consisting of a sum of powers in one or more variables (indeterminates) with non-negative integer exponents.

Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11                                        

(3a³ + 8a - 6) + (4a² - 9a + 11) = 3a³ + 4a² - a + 5

Answer:

the expression can be factored into (x+4)(23x + 7) and it is a product of two binomials.

Step-by-step explanation:

The expression 23x² + 6x + 7 is in the form of a quadratic equation. A quadratic equation is an equation in the form ax² + bx + c = 0, where a, b, and c are constants and x is the variable. In this case, the coefficients of the x², x, and the constant term are a = 23, b = 6, c = 7.

One way to factor a quadratic equation is by using the factoring by grouping method, where we group the terms in pairs and factor out the greatest common factor (GCF) from each group.

Here is one way to factor this equation:

23x² + 6x + 7 = (23x² + 6x) + 7

= (23x² + 6x) + 7

= (23x² + 6x + 6x) + 7

= (23x² + 12x) + 7

= (23x(x) + 3x(4)) + 7

= (23x(x+4) + 7)

= (x+4)(23x + 7)

So the expression can be factored into (x+4)(23x + 7) and it is a product of two binomials.

It's important to note that the above expression factors into a product of two binomials and not two factors of 23x² + 6x + 7

You can also use Quadratic formula to solve the above expression if this method seems confusing.

The number of used hamburgers that is 80% lean is = 500

and the number of used hamburgers that is 88% lean is = 300.

Let the number of hamburger that is 80% lean be = x.

So the number of hamburger that is 88% lean is = 800 - x

According to question after the mixing all these the total percentage of lean in 800 ponds of burgers is 83%.

So, the suitable mathematical equation is,

80% of x + 88% of (800 - x) = 83% of 800

(80/100) x + (88/100) * (800 - x) = (83/100) * 800

80x + 88 (800 - x) = 83 * 800 [Multiplying 1000 with both sides]

80x + 88 * 800 - 88x = 83 * 800

88x - 80x = 88 * 800 - 83 * 800 = 800 (88 - 83) = 5 * 800

8x = 800 * 5

x = (800 * 5)/8 = 100 * 5 = 500

Hence the number of hamburger with 80% lean is 500 and the number of hamburger with 88% lean is = (800 - 500) = 300.
