What are polynomials?

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

In keeping with the remarks, the simple answer is that all polynomials are functions, but not all functions are polynomials. A function is essentially a rule that allocates a codomain value to every domain value.

What is a function?

A relation is a function if it has only One y-value for each x-value.

The domain of a function is the set of values that we are allowed to plug into our function.

This set is the x values in a function such as f(x).

The range of a function is the set of values that the function assumes.

The function f(x) = 2x - 41 is a linear function.

As a linear function, the domain is all real numbers, and the range is also all real numbers.

So the domain is (-∞,∞) and range is (0,∞)

Hence,  the domain and range of function f(x) = 2x - 41 is domain (-∞,∞) and range is (0,∞).

When a patient with hypertension takes a particular type of blood pressure medication, the effects on the systolic pressure, S(t), can be measured by the following piecewise defined function: S of t is equal to the piecewise function of 140 minus 6 times t if 0 is less than or equal to t is less than or equal to 4 and 116 if 4 is less than t is less than 8 and 96 plus 8 times t if 8 is less than or equal to t is less than or equal to 12 where t is the time, in hours, since taking the medication. Based on the graph of the piecewise function, if the patient takes the blood pressure medication at 8 a.m., in which interval will their systolic pressure be lowest?

Answers

Based on the graph, the interval will their systolic pressure be lowest is 4pm to 5pm.

What is the interval in blood pressure ?

The lowest systolic pressure can be seen from 5 and 8 hours after taken the medication.

If we look at the time details then this will fall inbetween the interval of 2pm to 5pm.

According to question, the time range is 4pm to 5pm.

f(x)=12(x-10)2+18

What is the "a" value of this function?

Answers

Answer:

12

Step-by-step explanation:

Assuming that the 2  actually represents square, the equation is
[tex]f(x) = 12(x-2)^2 + 18[/tex]

[tex](x-2)^2 = x^2 - 4x + 4\\\\12(x-2)^2 + 18 = 12( x^2 - 4x + 4) + 18 = 12x^2 -48x + 48 + 18 = 12x^2 -48x + 66\\[/tex]

This equation is of the form
[tex]ax^2 + bx + c[/tex]

[tex]a = 12, b = -48, c = 66[/tex]

Note

Since the question is only asking for the a value which is the coefficient of x² it is clear that 12 is the coefficient without expanding (x-2)² but it is always better to proceed as above in case you are asked for b and c values also

Value of the function at x=a is [tex]12a^{2} -240a +1218[/tex].

Given function f(x)=[tex]12(x-10)^{2} +18[/tex]

We have to find the value of function at x=a.

For this we have to just put x=a in the function f(x)=[tex]12(x-10)^{2}+18[/tex]

f(a)=12[tex](a-10)^{2} +18[/tex]

we have to expand (x-10) to the power 2  to get the value of  function.

f(a)=[tex]12(a^{2} +10^{2} -20a)+18[/tex]

=[tex]12a^{2}+1200-240a+18\\[/tex]

=[tex]12a^{2} -240a+1218[/tex]

Hence the value of function at x=a is [tex]12a^{2} -240a+1218[/tex] means f(a)=[tex]12a^{2} -240a+1218[/tex].

Jaime makes the following claim.
An angle with a measure of π/3 radians in a circle with a radius of 3 inches is smaller than an angle with a measure of π/3 radians in a circle with a radius of 6 inches. This is because the radian measure is based on the length of the radius of the circle and a radius of 3 inches is smaller than a radius of 6 inches.

1. Review Jaime’s statement and what you know about angles and radians.
a. Explain whether you agree with Jaime’s statement or not.
b. Provide examples to support your whether you agree or disagree.

Answers

In the case above, Jaime claim is true.

The explanation to agree with Jaime’s statement or not is that the longer the length of the radius, the longer the length of the arc.What is the claim about?

1. Note that radian measure:

=   [tex]\frac{60° }{360°}[/tex] x 2π  x 3

= 1/6 x 6π  

= π  

2. Note that radian measure:

=  [tex]\frac{60° }{360°}[/tex] x 2π  x 6

= 1/6  x 2π  x 6

=2π  

So we can write it as:

Therefore, via the solution above, Jaime claim is true.

3. Note that: Radian measures: the percentage of arc measures x  2π  x radius and so one can say that The explanation to agree with Jaime’s statement or not is that the longer the length of the radius, the longer the length of the arc.
