Formula for area of circle (shape of pizza):
______________________________________________________
A = [tex] \pi [/tex] * r² ;
in which: "A = area of the pizza (area of a circle)" ; for which we are to solve.
"[tex] \pi [/tex]" = 3.14 (approximation we shall use) ;
r = radius = "d/2" ; d = diameter = 18.5 in (given) ;
r = d/2 = (18.5 in. / 2) = 9.25 in.
_______________________________________________
Plug our known values into the formula to solve for "A" (area):
A = [tex] \pi [/tex] * r² ;
= (3.14) * (9.25 in)² ;
= (3.14) * (9.25)² * (in²) ;
= (3.14) * (85.5625) * (in²) ;
= 268.66625 in² ;

Answers
The slope of the points (-8, 18) and (-14, -3) will be 7/2.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points are,
⇒ (-8, 18) and (-14, -3)
Now,
Since, We know that,
The slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) will be;
⇒ m = (y₂ - y₁) / (x₂ - x₁)
Hence, The slope of the line passing through the points (-8, 18) and
(-14, -3) will be;
⇒ m = (y₂ - y₁) / (x₂ - x₁)
⇒ m = (- 3 - 18) / (- 14 - (-8))
⇒ m = - 21 / (- 14 + 8)
⇒ m = - 21 / - 6
⇒ m = 7/2
Thus, The slope of the points (-8, 18) and (-14, -3) will be 7/2.

The student is asking to calculate the slope between two points, (-8, 18) and (-14, -3). By using the slope formula (rise over run), we computed the slope to be 3.5.
Explanation:The student is asking for the calculation of the slope between two points, which is a concept in algebra and coordinate geometry. To find the slope, you can use the formula:
slope = (y2 - y1) / (x2 - x1)Applying this to the given points (-8, 18) and (-14, -3), we find:
slope = (-3 - 18) / (-14 - (-8))= (-21) / (-6)
= 21/6
= 3.5
Therefore, the slope is 3.5.

Answers
Explanation:
The side lengths of the golden rectangle are in the proportion:
1
--------------------
golden number
The golden numbrer is:
1 + √5
-----------
2
So, the ratio is:
1
--------------
1 + √5
---------
2
And, using the properties of the division of fractions, that is equivalent to:
2
-------------
1 + √5
Since you have the given side t = 9, you can set the proportion, to find the unknown lenght, s:
2 s
--------- = ---------
1 + √5 t
2 s
--------- = ---------
1 + √5 9
And you can solve for s:
s = 9 * 2 / (1 + √5) ≈ 18 / (1 + 2.236) = 18 / (3.236) ≈ 5.56.
Which is the option a. 5.56
To determine the unknown side length of a golden rectangle, set up a proportion and solve a quadratic equation.
Explanation:The golden rectangle is a rectangle in which the ratio of the longer side to the shorter side is equal to the golden ratio, approximately 1.618. To determine the unknown side length, we can set up a proportion using the given side length and the golden ratio:
s / t = (s + t) / s
Substituting the given values, we have:
s / 9 = (s + 9) / s
Cross multiplying and simplifying, we get:
s^2 = 9(s + 9)
By solving this quadratic equation, we find that the unknown side length is approximately 4.94. Therefore, the correct answer is c. 4.94.

Using the properties of exponents, the expression is simplified as (4/3)x⁵y².
What is the simplification of the expression?To simplify the given expression, we need to use properties of exponents
Taking the numerator;
[(2x³y)⁴] = (2⁴)(x³)⁴(y)⁴ = 16x¹²y⁴
Next, let's simplify the denominator:
3x²(4x⁵y²) = 3 * 4 * x² * x⁵ * y² = 12x⁷y²
This can be expressed as;
[(2x³y)⁴] / [3x²(4x⁵y²)] = (16x¹²y⁴) / (12x⁷y²)
Take the common factors and divide both of them;
(16x¹²y⁴) / (12x⁷y²) = (4/3)(x¹² / x⁷)(y⁴ / y²) = (4/3)x¹²⁻⁷y⁴⁻² = (4/3)x⁵y²

a jogger ran 3 miles due east of his house. then he ran 5 miles at a heading of 30 east of north. how far is he from his house after running 8 miles?
Answers
Final answer:
The jogger is approximately 7 miles from his house after running 3 miles east and then 5 miles at a 30° angle east of north, calculated using trigonometric functions and the Pythagorean theorem.
Explanation:
The question asks how far a jogger is from his house after running a total of 8 miles, initially 3 miles due east and then 5 miles at a 30° angle east of north. To solve this, we can use trigonometric functions to find the resultant displacement. The first leg of the journey is straightforward, 3 miles directly east. The second leg can be broken into its northward and eastward components using sine and cosine functions, with the length of the leg being the hypotenuse.
Northward component: 5 miles × cos(30°) = 4.33 miles
Eastward component: 3 miles (initial) + (5 miles × sin(30°)) = 3 + 2.5 = 5.5 miles
To find the total displacement, we calculate the straight-line distance from the starting point to the end point using the Pythagorean theorem.
Displacement = √(northward component² + eastward component²) = √(4.33² + 5.5²) = √(18.7489 + 30.25) = √(48.9989) = 7 miles approximately.
Therefore, the jogger is approximately 7 miles from his house.
To find the distance and direction from the starting point after the jogger's two separate runs, we apply vector addition by decomposing the second leg into its components with trigonometry and then use the Pythagorean theorem and arctangent function to find the resultant magnitude and direction.
Explanation:The question involves determining the distance from the starting point after a two-leg journey with given directions and distances. To solve this, we need to apply principles of vector addition to combine the two displacements into one resultant displacement. The first displacement is due east, and can be represented as a straight line on a horizontal axis. The second displacement, at a 30° angle east of north, requires us to decompose it into its northward and eastward components. These components are found using trigonometry: by multiplying the distance by the cosine (for the eastward part) and sine (for the northward part) of the angle.
After computing the respective components of the second displacement, we add both eastward displacements together and both northward displacements together to find the total displacement in the east and north directions. The final step is to use the Pythagorean theorem to determine the magnitude of the resultant vector, and trigonometry (specifically, the arctangent function) to find the direction of the resultant vector from the origin, which provides the required distance and direction from the jogger's house after running.

C)82 Degrees F
Step-by-step explanation:
The formula we have is F = 9/5C + 32. Substituting the value for Celsius, 28, into the formula,
F = 9/5(28) + 32
F = 1.8(28) + 32
F = 50.4 + 32
F = 82.4
To the nearest whole number, this is 82 degrees.
The converted temperature in degrees Fahrenheit is 82 Degrees F
What is temperature conversion?Temperature conversion is the process of changing the value of temperature from one unit to another. We measure temperature on scales like Kelvin, Celsius, and Fahrenheit, etc.
