If a person weighs 290 lbs, how much of a dosage should they get every 4 hours if they need to be
administered 11.9 mg/kg? Round to 1 decimal.

Answer:

0.25x+1.75

Step-by-step explanation:

A linear equation is of the form ax+b. Set a up a system of equation with -3 and 13 substituted in to ax+b. We get -3a+b=1 and 13a+b=5. Solving tis gives us a,b=(0.25,1.75)

Answer:

f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

a linear function has the form

f(x) = ax + b ( a and b have to be found )

given f(- 3) = 1 and f(13) = 5 , then by substitution

- 3a + b = 1 → (1)

13a + b = 5 → (2)

subtract (2) from (1) term by term to eliminate b

- 3a - 13a = 1 - 5

- 16a = - 4 ( divide both sides by - 16 )

a = [tex]\frac{-4}{-16}[/tex] = [tex]\frac{1}{4}[/tex]

substitute a = [tex]\frac{1}{4}[/tex] into (1) and solve for b

- 3( [tex]\frac{1}{4}[/tex] ) + b = 1

- [tex]\frac{3}{4}[/tex] + b = 1 ( add [tex]\frac{3}{4}[/tex] to both sides )

b = 1 [tex]\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]

f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex] ← is the linear function

or

f(x) = 0.25x + 1.75

The percentage of the increase in population is 4%

From the question, we have the following parameters that can be used in our computation:

Initial population = 209000

New population = 2017360

The percentage of the increase is then calculated using the following percentage equation

Percentage increase = (New population  - Initial population )/Initial population  * 100%

Substitute the known values in the above equation, so, we have the following representation

Percentage increase = (217360 - 209000)/209000 * 100%

Evaluate

Percentage increase = 4%

Hence, the increase percentage is 4%

The domain of the equation is 10 days and the range is the $14 left in the account.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

a) The independent variable in this problem is the number of days, represented as x. The amount of money left, the y variable is the dependent variable since it depends on the number of days left (x).

b) If there are 10 days left, we can plug it into the given equation to find the balance in the account.

y = -3x + 44                    

y = -3(10) + 44                

y = -30 + 44                    

y = 14

One of the possible x-values of point F will be 6 units to the right of point G. So, the x-value of point F could be 7, since 1+6=7. That means one possible location of point F is (7,8).

The other possible x-value of point F will be 6 units to the left of point G. So, the x-value of point F could be -5, since 1–6=–5. That means the other possible location of point F is (–5,8).

So the answer is:

Since Anthony is 30, the largest amount he can contribute and deduct from his Form W-2 for the traditional IRA for 2021 is $6,000.

The traditional IRA or individual retirement account is a pre-tax contribution an employee saves towards retirement.

With a traditional IRA, Anthony can contribute pre- or after-tax dollars, allowing his savings to grow tax-deferred while withdrawals are taxed as current income unless after the age of 59½.

An additional tax of 10% may apply if Anthony withdraws from his traditional IRA before reaching 59½ years.

However, one advantage of the traditional IRA is that the employee invests more funds upfront since the deduction is mostly made before tax.

Thus, I will advise Anthony to deduct a maximum of $6,000 from Form W-2 towards his traditional IRA to save more money in advance.

Answer: The answer is -9

Order of operations/PEMDAS:

Parenthesis, Exponents, Multiplication,

Division, Addition, Subtraction

Here is why:

using the order of operations,

do 4/-2 First

4/-2 = -2

Then do -7 + (-2)

-7 + (-2) = -2

When adding a negative plus a negative, it stays negative,

so the expression -7 +(-2) is like 7+2, it will equal 9, but because it is a negative plus a negative, the answer is negative.

For the given function, h(x) = x² - 1, over the interval -3 ≤ x ≤ -1, the average rate of change is 4.

A function is a combination of different types of variable and constants in which for the different values of x the value of function y is unique.

The given function is,

h(x) = x² - 1, and the interval is -3 ≤ x ≤ -1.

To find average rate of change for the function,

Use formula,

Average rate of change = [tex]\frac{h(b)- h(a)}{b-a}[/tex]

h(b) = h(-1) = (-1)² - 1 = 0

h(a) = h(-3) = (-3)² - 1 = 8

Step-by-step explanation:

We can solve this using PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). We do parentheses first, then exponents, all the way down to subtraction:

1. Parentheses

(1 + 3)³ -(2)2 + 4

4³ - (2)2 + 4

(By the way, (2)2 is considered multiplication not parentheses).

2. Exponents

4³ - (2)2 + 4

64 - (2)2 + 4

3. Multiplication

64 - (2)2 + 4

64 - 4 + 4

4. Division

The linear function that shows the proportional relationship between the distance and time is d = 100t

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.

A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,

From the table given, we can find the slope of the function by using the formula

m = y₂ - y₁ / x₂ - x₁

m = 300 - 200 / 3 - 2

m = 100

To find the y - intercept,

y = mx + c

300 = 100(3) + c

300 = 300 + c

c = 300 - 300

c = 0

The equation that shows the relationship is

d = 100t

For the given quadratic equation we have:

a) F(-2) = 5

b) F(3) = 40

c) the solutions are:

t = -1

t = -1/3

Here we have the following quadratic function:

F(t) = 3t^2 + 4t + 1

a) First, we want to determine the value of F(-2), to do so, we just need to replace the values of the variable, t, by the number -2, we will get:

F(-2) =3*(-2)^2 + 4*(-2) + 1

F(-2) = 3*4 - 8 + 1 = 5

F(-2) = 5

b) Now we want to find the value of the F(3), so this time we evaluate in x = 3.

F(3) =3*3^2 + 4*3 + 1

F(3) = 27 + 12 + 1 = 40

F(3) = 40

c) Last, we want to solve:

F(t) = 0

So we need to solve the quadratic equation:

3t^2 + 4t + 1 = 0

Using the quadratic formula we will get the two solutions:

[tex]t = \frac{-4 \pm \sqrt{4^2 - 4*3*1} }{2*3} \\\\t = \frac{-4 \pm 2}{6}[/tex]

The equation in slope-intercept form to model the cost in dollars, y, for x refills is 3.50 = 2.50x + b.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given that movie theater sells popcorn in a reusable bucket for $3.50. They offer refills for $2.50 each.

The value of y  is popcorn cost = $3.50

The slope will be $2.50

Therefore, the equation is y = mx + b

Plug the values; y = 3.50 and m = 2.50

3.50= 2.50x + b

Hence, the equation in slope-intercept form to model the cost in dollars, y, for x refills is 3.50= 2.50x + b.
