The minimum of the periodic sine function is - 4 and it's amplitude is |4|.

If there is a positive real number P such that f(x + P) = f(x), for all x being real numbers, then the function y= f(x) is said to be periodic. The fundamental period of a function is the least value of the positive real number P. The period during which a function repeats itself is also known as the fundamental period of the function.

f(x + P) = f(x).

From the graph, we conclude it is a sine function.

The amplitude of the graph is 4 units.

So, The graph reaches it's maximum and minimum at ± 4.

Therefore, The minimum of the function is - 4.

a) The amount of money that Tony invested is; £1350

b) The rate of compound interest is; 4%

c) The graph that represents the growth in Toni's account is; Graph C

The formula for the total value of her investment  after t years is given by the formula; v = 1350 * 1.04^t

The general formula used to calculate the interest rate is given by,

a = p * (1 + r)^t

where;

a is amount

p is principal

r is rate of interest

t is time period

Comparing the given equation with standard equation, we have;

a = v  

p = 1350

t = t    

Now, 1 + r = 1.04

1 + r = 1 + 0.04

Thus;

r = 0.04  = 4%

Therefore, the money invested by tony P = £1350

The Best Lawn covers the most area per pound is better choice to buy.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Xtra Green covers 1/20 of an acre with 1/2 of a pound of fertilizer granules.

So, area per pound covered by Xtra Green

= (1/20)  /(1/2)

= 1/20 x 2/1

= 1/10

= 0.1

Best Lawn covers 1/15 of an acre with 1/5 of a pound of fertilizer granules.

So, area per pound covered by Best Lawn

= (1/15)  /(1/5)

= 1/15 x 5/1

= 1/3

= 0.333

Hence, Best cover larger Area is better choice.

The fraction 7/3 cannot be expressed as a whole number. The fraction 7/3 can be expressed as a decimal, which is 2.3333.... and goes on forever, or as a mixed number, which would be 2 and 1/3.

It's important to note that when dividing two integers, the result is not guaranteed to be a whole number.

Step-by-step explanation:

The first statement is true and the second statement is false.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given that initial population of bacteria = 80

Bacteria triple in population every 5 hours.

Number of bacteria after the time 'x' hours is modeled as,

f(x) = [tex](80)(3)^\frac{x}{5}[/tex] which is given in the first statement.

So the first statement is true.

After 13 hours,

f(13) =  [tex](80)(3)^\frac{13}{5}[/tex]

      = 1391.89 ≈ 1392

But the second statement says the population is 1592 bacteria, which is false.

The solution to the quadratic equations are

a) The number of seconds for the ball to reach the ground is t = 5 seconds

b) The number of seconds to reach the maximum height T = 2 seconds

c) The maximum height of the ball is h ( 2 ) = 144 feet

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as h ( t )

Now , the equation will be

h ( t ) = -16t² + 64t + 80   be equation (1)

a)

The number of seconds for the baseball to reach the ground be t

The height when the ball reaches the ground will be h = 0

Substituting the value of h ( t ) = 0 , we get

0 = -16t² + 64t + 80

On simplifying the equation , we get

16t² - 64t - 80 = 0

Divide by 16 on both sides of the equation , we get

t² - 4t - 5 = 0

On factorizing the equation , we get

t² + t -5t - 5 = 0

t ( t + 1 ) - 5 ( t + 1 ) = 0

( t - 5 ) ( t + 1 ) = 0

The value of t is time and it is not negative

So , when ( t - 5 ) = 0

Adding 5 on both sides of the equation , we get

t = 5 seconds

b)

The number of seconds the baseball to reach the maximum height be T

And graph of the function is a parabola open down because the leading coefficient is negative. Therefore, to get the maximum height we just have to find the vertex of this parabola

T = ( -b / 2a )

On simplifying the equation , we get

T = ( -64 / ( 2 ( 16 )

T = -64 / 32

T = 2 seconds

c)

The maximum height of the baseball is when T = 2

Substituting the value of t = 2 in the equation , we get

h ( t ) = -16t² + 64t + 80

h ( 2 ) = -16 ( 2 )² + 64 ( 2 ) + 80

On simplifying the equation , we get

h ( 2 ) = -64 + 128 + 80

h ( 2 ) = 64 + 80

h ( 2 ) = 144 feet

Hence , the equation is solved

To find the length of the part of the ramp that is on the ground, we need to know the angle of the ramp and the height of the ramp. If the height of the ramp is 6 inches, and we know the angle of the ramp, we can use the Pythagorean theorem to find the length of the ramp.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the ramp in this case) is equal to the sum of the squares of the other two sides. If we call the length of the ramp "x", and the height of the ramp "h", we can write the equation as:

x^2 = h^2 + (6 inches)^2

We don't have the angle of the ramp, so we can't use the Pythagorean theorem. Therefore, we can't find the length of the part of the ramp that is on the ground with the information given.

Let's call the first number in the series "x", and the last number in the series "y".

We know that the series is a consecutive series of odd numbers, and we also know that y is 6 less than the last number in the series.

Since the series is a consecutive series of odd numbers, we can say that the difference between any two consecutive numbers in the series is 2.

So, we can write an equation to represent this information:

y = x + (n-1) * 2

where n is the number of numbers in the series.

We also know that y is 6 less than the last number in the series, so we can add this information to our equation:

y = x + (n-1) * 2 - 6
