The most equitable way to share the coin between Mai and Jeff is ratio 5:3. Mai will have 5 coins and Jeff 3 coins
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. The general form of representing a ratio of between two quantities say 'a' and 'b' is a: b.
Mai dropped 5 loaves and Jeff 3 loaves. This means that the ratio of brad dropped by Mia and Jeff is 5:3.
The stranger dropped 8coins. the most equitable way to share the coin is to share it in ratio 5:8
Using this ratio, the total ratio is 8

y is directly proportional to x3 When x = 10, y = 250
(a) Find a formula for y in terms of x.
The formula for y in terms of x is a cubic equation:
y = 0.25*x³
How to find the relation between x and y?We know that y is directly proportional to x³, then we can write the equation:
y = k*x³
Where k is the constant of proportionality.
In this case, we know that when x = 10, the value of y is 250, then we can replace these values in the above equation to find the value of x:
250 = k*10³
250 = k*1,000
Dividing both sides by 1,000 we get:
250/1,000 = k
0.25 = k
Then the equation is:
y = 0.25*10³

The path of a baseball is modeled by the equation [tex]y=-0.25x^{2} +4x+3[/tex] where x represents the time (in seconds) and y represents the height of the baseball.
- Find and interpret the y-intercept. Find the maximum height of the baseball. Then sketch a graph of the path.
(please provide steps on how to solve if you can)
Answer:
The y-intercept is when $x=0$ so $y=32\frac{ft}{s}*0-\frac{1}{2}*9.8*0^2=0$, so the ball starts on the ground. The maximum height is when $v=0$, so $0=32\frac{ft}{s}-9.8t$ and solving for $t$ we get $t=\frac{32}{9.8}=3.265s$, and plugging this back in for $y$ we get $y=32\frac{ft}{s}*3.265s-\frac{1}{2}*9.8*3.265^2=156.205 ft$. So the ball will be at its maximum height of 156.205 ft at 3.265 seconds.
Step-by-step explanation:
The $y$-intercept is $-1$. The maximum height of the baseball is when $y=0$; that is when $x=\ln(4)$. Here is a sketch of the path.
From the $y$-intercept, we see that the baseball starts at height $y=-1$. It reaches a maximum height at $x=\ln(4)$; that is, $y=0$. From there, it falls and reaches the ground at $x=2\ln(4)$; that is, $y=-1$ again.

(a) Calculate the (1) return on assets, (2) asset turnover, and (3) profit
margin. (Round answers to 1 decimal place, e.g. 6.2% and 6.2.)
The calculation of the required financial ratios for Sunland Company is as follows:
The return on assets is 6%.
The Asset Turnover is 2.06 times.
The profit margin is 2.9%.
What are financial ratios?Financial ratios express the numerical relationships of two or more financial statement elements.
Financial ratios are used to make comparisons of the financial performance or position of companies from one year to another (trend analysis) and between companies or the industry average.
Net sales $11,257.9
Net earnings $327.9
Total assets, ending = $5,560.0
Total assets, beginning = $5,370.0
Average assets = (Beginning total assets + Ending total assets) ÷ 2
= $5,465 ($5,560 + $5,370)/2
Return on assets = Net earnings/Average total assets x 100
= 6% ($327.9/$5,465 x 100)
Asset Turnover = Net Sales/Average total assets
= 2.06x ($11,257.9/$5,465)
Profit margin = Net earnings/Net Sales x 100
= 2.9% ($327.9/$11,257.9 x 100)

What is the equation of a circle with a center at (-4, 0)
that passes through the point (-2, 1)?
O x² + (y + 4)² = √√5
O (x-1)² + (y + 2)² = 5
O (x + 4)² + y² = 5
O (x + 2)2 + (y - 1)² = √5
The equation of a circle with a center at (-4, 0) that passes through the point (-2, 1) is (x + 4)² + y² = 5. Option C is correct.
The standard equation of a circle is given by:
(x – h)² + (y – k)² = r²
Where (h, k) is the center of the circle and r is the radius.
We are given:
The circle has a center at (–4, 0) and passes through the point (–2, 1).
Substitute (h, k) with (–4, 0) in the above equation, we will get;
(x – (-4))² + (y – 0)² = r²
(x + 4)² + y² = r²
Substitute (x, y) with (–2, 1) in the above equation to get the value of r:
(-2 + 4)² + 1² = r²
(2)² + 1² = r²
r² = 5
Put the value r² = 5 in (x + 4)² + y² = r², we will get;
(x + 4)² + y² = 5
So, the equation of the circle is (x + 4)² + y² = 5.
Thus, the equation of a circle with a center at (-4, 0) that passes through the point (-2, 1) is (x + 4)² + y² = 5. Option C is correct.

Answer:
38.88in²
Step-by-step explanation:
Area of shaded region = Area of square - Area of semi circle
First lets find the area of the square and semi circle
Area of square = s²
Where s = side length
Here we have a given side length of 8in
So s = 8
This means area = 8² = 64in²
Area of semicircle = (πr²)/2
Where r = radius
Here, the side length of the square and the diameter of the semicircle is shared meaning they are congruent. This means the diameter of the semicircle = 8in
To convert from diameter to radius we simply divide by 2
So radius = 8 / 2 = 4
Now we have Area = (πr²)/2
==> plug in r = 4 and π = 3.14
Area = (3.14(4)²))/2
==> simplify exponent
Area = (3.14(16))/2
==> multiply 3.14 and 16
Area = 50.24/2
==> simplify division
Area = 25.12in²
Area of shaded region
We now subtract the two areas
Area of shaded region = Area of square - Area of semi circle
Area of square = 64in² and Area of semicircle = 25.12in²
Area of shaded region = 64in² - 25.12in² = 38.88in²

hours
The time taken by Ashley and Laura to meet each other is 3 hrs
Relationship Between Time, Speed & Distance:The speed of an object tells us how slow or fast an object moves. The formula for speed is given below
Speed = Distance/TimeThe speed of an object is directly proportional to Distance and Inversely proportional to Time. Hence,
Distance = Speed X TimeHere we have,
Ashley and Laura are 60 miles apart, traveling toward each other
This means the distance between Ashley and Laura is 60 miles
Speed of Laura = 12 mph
Speed of Ashley = 8 mph
Let us assume that Both Ashley and Laura meet after t hours
Then
The distance traveled by Laura in t hours = 12 mph × t hrs = 12t m
The distance traveled by Ashley in t hours = 8 mph × t hrs = 8t m
As we know the distance between Laura and Ashley is 60 miles
=> 12t m + 8t m = 60 miles
=> 20t miles = 60 miles
=> t = 60/20

Determine the domain and range of the following parabola. f(x)=−3x2−30x−74
Step-by-step explanation:
1. if to rewrite the given equation, then
y= -3(x+5)²+1;
2. the vertex of the parabola is (-5;1) and it is the highest point. Then
3. domain: x is any value, x∈(-∞;+∞);
range: y not greater than 1, y∈(-∞;1].
For the parabola f(x) = -3x² - 30x - 74, the domain is all real numbers (-∞, ∞), and the range is also all real numbers (-∞, ∞).
To determine the domain and range of the given parabola f(x) = -3x² - 30x - 74, we need to understand the behavior of parabolas.
The domain of a function represents all the possible x-values for which the function is defined. In this case, there are no restrictions on the x-values for the given quadratic function. Therefore, the domain is all real numbers, expressed as (-∞, ∞).
The range of a function represents all the possible y-values that the function can produce. For a parabola, if the coefficient of the squared term (in this case, -3) is negative, the parabola opens downward. Since the coefficient is negative, the parabola will have a maximum value. In this example, there is no minimum or maximum specified; thus, the range will also be all real numbers.
