The populations, considering an exponential function, are given as follows:
P(1) = 19.2.P(2) = 23.04.P(12) = 142.66.What is an exponential function?An increasing exponential function is modeled according to the rule presented as follows:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which the variables of the function are:
A(0) is the initial amount of the function.r is the growth rate of the function, as a decimal.In this problem, the parameters are given as follows:
A(0) = 16, r = 0.2.
Hence the function, written as P(t), is:
[tex]P(t) = 16(1.2)^t[/tex]
The numeric values are found replacing the lone instance of t by the value at which we want to find the numeric value, hence:
P(1) = 16 x (1.2)¹ = 19.2.P(2) = 16 x (1.2)² = 23.04.P(12) = 16 x (1.2)¹² = 142.66.More can be learned about exponential functions at https://brainly.com/question/25537936

the general solution to such a quadratic equation

John buys 7 apples and 4 pears for $7.25. At the same prices, Hayley buys 5 apples and 9 pears for $10.40. What is the price of one pear? Use Cramer’s Rule to solve.
Answers
The price of one pear is $0.85
How to use Cramer’s Rule to solve the price of one pear?
Cramer's rule is one of the useful methods used for solving a system of equations. In this method, the values of the variables in the system are to be calculated using the determinants of matrices. Thus, Cramer's rule is also known as the determinant method.
Given that: John buys 7 apples and 4 pears for $7.25 and at the same prices, Hayley buys 5 apples and 9 pears for $10.40
We will use this given information to form equations in matrices form. Let a and p represent the prices of one apple and one pear respectively.
The equation is:
7a + 4p = 7.25
5a + 9p = 10.40
The matrix formed is:
[tex]C=\left[\begin {array}{ccc}7&4\\5&9\end{array}\right][/tex] , [tex]b=\left[\begin {array}{ccc}7.25\\10.40\end{array}\right][/tex]
Find the determinants,
D = (7 x 9) - (5 x 4) = 43
Da = (7.25 x 9) - (10.40 x 4) = 23.65
Dp = (7 x 10.40) - (5 x 7.25) = 36.55
a = Da/D = 23.65/43 = 0.55
p = Dp/D = 36.55/43 = 0.85
Since p = 0.85. Therefore, the price of one pear is $0.85

Answers
The share Kyle sells worth $55000 and Kyle's gain amount is $5000
Given,
The share bought by Kyle of company XYZ = $50,000
The share price = $100
The share price after an year = $110

1. The cost of bell peppers varies directly with the weight of bell peppers, as shown in the table. Write a direct variation equation to represent this relationship. Then identify the constant of variation and interpret its meaning.
Answers
The constant of variation is 1.75 for every unit increase in x (weight), and the cost(y) value increases by $ 1.75.
What is the equation?
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The difference between two consecutive entries is constant, as we can see = 1.75
⇒ 7 - 5.25 = 1.75
⇒ 8.75-7 = 1.75
⇒ Slope(m) = 1.75
The slope represents the variable's rate of change.
y - 3 = m(x - 5.25)
y - 5.25 = 1.75(x-3)
y = 1.76x
Thus, the constant of variation is 1.75
This indicates that for every unit increase in x (weight), the cost(y) value increases by $ 1.75.

When an object is thrown upward, its height (S), in meters, is given (approximately) by the quadratic equation
S = -5t² + vt + h, where v is the upward initial velocity in meters/second, t is the time of flight in seconds, and h is the
height above level ground from which the object is thrown. Johnny is standing on a platform 16 meters high and
throws a ball straight up as high as he can at a velocity of 16 meters/second. At what time t will the ball hit the
ground?
The ball will strike the ground
seconds after it is thrown.
Answers
Check the picture below.
[tex]~~~~~~\textit{initial velocity in meters} \\\\ S = -5t^2+v_ot+h_o \quad \begin{cases} v_o=\textit{initial velocity}&16\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&16\\ \qquad \textit{of the object}\\ h=\textit{object's height}&\\ \qquad \textit{at "t" seconds} \end{cases} \\\\\\ 0=-5t^2+16t+16\implies 5t^2-16t-16=0 \\\\\\ (5t+4)(t-4)=0\implies t= \begin{cases} -\frac{4}{5}\\\\ 4 ~~ \textit{\LARGE \checkmark} \end{cases}[/tex]
the equation for meters is usually as you see in the picture but for this exercise it got rounded from -4.9 to -5, which is fine.
let's notice that "t" has two values, however the seconds cannot be a negative value, so we dismiss that one.
The ball will strike the ground 4 seconds after it is thrown When an object is thrown upward, its height , in meters, is given by the quadratic equation S = -5t² + vt + h
To find the time at which the ball will hit the ground, we need to determine when the height (S) of the ball becomes zero. At that moment, the ball will be at ground level.
The height (S) of the ball is given by the quadratic equation:
S = -5t² + vt + h
where:
S = height of the ball in meters
t = time of flight in seconds
v = initial velocity in meters/second (upward velocity, so it's positive)
h = height above level ground from which the object is thrown
Given that the initial velocity (v) is 16 meters/second, and the height above the ground (h) is 16 meters, we can substitute these values into the equation:
S = -5t² + 16t + 16
Now, to find the time (t) at which the ball hits the ground, we need to solve for t when S = 0:
0 = -5t² + 16t + 16
This is a quadratic equation in standard form (ax² + bx + c = 0), and we can solve it by factoring or using the quadratic formula. In this case, let's use the quadratic formula:
The quadratic formula is given by:
t = (-b ± √(b² - 4ac)) / 2a
In our case, a = -5, b = 16, and c = 16. Plugging these values into the quadratic formula:
t = (-(16) ± √(16² - 4*(-5)16)) / 2(-5)
t = (-16 ± √(256 + 320)) / -10
t = (-16 ± √576) / -10
Now, find the two possible solutions for t:
t₁ = (-16 + √576) / -10
t₁ = (-16 + 24) / -10
t₁ = 8 / -10
t₁ = -0.8 seconds
t₂ = (-16 - √576) / -10
t₂ = (-16 - 24) / -10
t₂ = -40 / -10
t₂ = 4 seconds
We have two solutions for t: t = -0.8 seconds and t = 4 seconds. However, we can disregard the negative value for time, as time cannot be negative in this context.
So, the ball will strike the ground 4 seconds after it is thrown.

The measure of the largest angle in a triangle is 110° larger than the sum of the measures of the other two angles. The measure of the smallest angle is three-
quarters the measure of the middle angle. Find the measure of each angle.
Answers
Measure of largest. smallest and middle angle of a triangle under given conditions is 145°, 15° and 20° respectively.
What is angle sum property of a triangle?
Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
According to the given question:
Let the measure of middle angle = x
The measure of the smallest angle is three-quarters the measure of the middle angle.
∴ Smallest angle = (3/4)x
The measure of the largest angle in a triangle is 110° larger than the sum of the measures of the other two angles.
∴ Largest angle = 110° + x + (3/4)x
Now, by Angle sum property of a triangle
x + (3/4)x + 110° + x + (3/4)x = 180°
On solving for the value of x we get
2x + (3/2)x = 70°
7x = 140°
x = 20°
Therefore,
measure of middle angle x = 20°
measure of smallest angle (3/4)x = 15°
measure of the largest angle 110° + x + (3/4)x = 145°
