What is a dollar?

The United States dollar (symbol: $; code: USD; often abbreviated US$ or U.S. Dollar to differentiate it from other dollar-denominated currencies; known colloquially as the dollar, U.S. dollar, American dollar, or buck) is the official currency of the United States and numerous other nations. The Coinage Act of 1792 established the United States dollar on equal footing with the Spanish silver dollar, split it into 100 cents, and permitted the minting of coins denominated in dollars and cents. Federal Reserve Notes, generally known as greenbacks owing to their predominately green hue, are the currency of the United States.

Given, 1 U.S. dollar = 5.8 Egyptian pounds

so, 48.50 U.S. dollars = 5.8 x 48.50 = 281.30 Egyptian pounds

(a). The domain of the function C(t) based on the context of the problem  is t≥0

(b). The greatest concentration of the medication  that a patient will have in their body is 7mg/L

Graphs are used to show the relationship between variables, where the variables are represented by a pair of axes.

(a). C(t) = (-8t² +50t)/(t² + 3t +2 )

The domain of the function :

Because the medication concentration C(t) is a function of time (t), the domain is the possible values t can take.

t, cannot take negative values (i.e. it is not possible to have a negative time).

The least possible value of t is 0

So, the domain of the function based on the context is:  t≥0

(b).From the graph, the maximum y-value is 7.

Hence, the greatest concentration of the medication is 7mg/L

According to the given function,

Domain = [tex]\left(-\infty, -4\right) \cup \left(-4, 2\right) \cup \left(2, \infty\right)[/tex]

Vertical Asymptote = 4

Horizontal Asymptote = 0

X - intercept = No x - intercepts

Y - intercept = 1/4

Domain:

The  the domain of a function referred as the set of inputs accepted by the function

Given,

The function is,

[tex]f(x)=\frac{x-2}{x^2+2x-8}[/tex]

Here we need to find the domain, vertical asymptote, horizontal asymptote,  x - intercept, and y-intercept.

To find the domain and intercepts, we have to plot the graph for the given function.

So, the graph of the function is attached below. It can be drawn using the graphing calculator.

As per the graph,

Domain = [tex]\left(-\infty, -4\right) \cup \left(-4, 2\right) \cup \left(2, \infty\right)[/tex]

And the values of

x - intercept = No x-intercepts

y - intercept = 1/4

Now, the vertical asymptote is calculated as,

The line x=L is a vertical asymptote of the function f(x), if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.

x = -4

Then,

[tex]\lim_{x \to -4^+} \frac{1}{x + 4}=\infty[/tex]

Since the limit is infinite, then x=−4 is a vertical asymptote.

And the horizontal asymptote is,

Line y=L is a horizontal asymptote of the function y=f(x), if either '

[tex]\lim_{x \to \infty} f{\left(x \right)}=L[/tex] or [tex]\lim_{x \to -\infty} f{\left(x \right)}=L[/tex]  and L is finite.

When we calculate the limits:

[tex]\lim_{x \to \infty}\left(\frac{x - 2}{x^{2} + 2 x - 8}\right)=0\\\\\lim_{x \to -\infty}\left(\frac{x - 2}{x^{2} + 2 x - 8}\right)=0[/tex]

Thus, the horizontal asymptote is y=0.

Answer: Do you know the answer to this yet??

Step-by-step explanation:

The equation is 4x + 2y = 45 and The y-intercept is the point (0,22.5) and The x-intercept is the point (11.25, 0)

Given,

Kevin took $45 with him to spend on snack

and, The price for each bucket of popcorn was $4.

To plot the graph

Now, According to the question:

Sketch the graph that represents the situation and label the intercepts

Let,

x ------> the number of bags of popcorn

y -----> the number of drinks.

we know that

The price for each bag of popcorn was $4

The price of each drink was half the price of a bag of popcorn

So, The price of each drink was (1/2)$4 = $2

The total bags of popcorn multiplied by $4 plus the number of drinks multiplied by $2 must be equal $45

The equation that represent this situation is :

4x + 2y = 45 -----(1)

Now, Find the y - intercept form:

The y-intercept is the value of y when the value of x is equal to zero

For, x = 0 put the value of x in equation(1)

4(0) + 2y = 45

2y = 45

y = 22.5

The y-intercept is the point (0,22.5)

That means -----> The number of drinks that Kevin can buy when the number of bags of popcorn is equal to zero

For, y = 0 put the value of x in equation(1)

4x + 2(0) = 45

4x = 45

x = 11.25

The x-intercept is the point (11.25, 0)

That means -----> The number of drinks that Kevin can buy when the number of bags of popcorn is equal to zero

Hence, The equation is 4x + 2y = 45 and The y-intercept is the point (0,22.5) and The x-intercept is the point (11.25, 0)

Answers:

x = 108

y = 111/5 = 22.2

========================================================

Explanation:

The angles 72 and x form a 180 degree straight line.

72+x = 180

x = 180-72

x = 108

Angles x and 5y-3 are congruent corresponding angles assuming the lines pointing to the northwest are parallel

5y - 3 = x

5y - 3 = 108

5y = 108+3

5y = 111

y = 111/5

y = 22.2

Answer:

x = 108°

y = 22.2°

Step-by-step explanation:

Angles on a straight line sum to 180°.

[tex]\implies 72^{\circ} + x = 180^{\circ}[/tex]

[tex]\implies 72^{\circ} + x - 72^{\circ} = 180^{\circ} - 72^{\circ}[/tex]

[tex]\implies x = 108^{\circ}[/tex]

Corresponding Angles Theorem

When a straight line intersects two parallel straight lines, the angles in the same relative position are congruent.

Assuming the two lines that appear parallel in the given diagram are parallel:

[tex]\implies (5y - 3)^{\circ} = x^{\circ}[/tex]

[tex]\implies 5y - 3 = 108[/tex]

[tex]\implies 5y - 3 + 3 = 108 + 3[/tex]

[tex]\implies 5y = 111[/tex]

[tex]\implies 5y \div 5 = 111 \div 5[/tex]

[tex]\implies y = 22.2^{\circ}[/tex]

The values of x must be greater than 4 for the inequality (x-4)² > 0 to be true.

Given inequality is (x - 4)² >0.

To solve the inequality, take square root on both sides

So, (x - 4) > 0

Adding 4 on both sides,

Seven times the sum of a number and 9 is 5 then the number is -58/7 .

A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, thousand, or a million. There are summations with an infinite number of terms.

We have been given that

Seven times the sum of a number and 9 is 5

Let the number is n.

let's write "the sum of a number and 9"

n + 9 .

Then, "seven times" the sum can be written as:

7 (n + 9)

This "is 5" or "is equal to 5" and can be written as:

7 (n + 9) = 5

To solve, first expand the term in parenthesis on the left side of the equation by multiplying each term in the parenthesis by

(7×n) + (7×9) = 5

7n + 63 = 5

Next, subtract 63 from each side of the equation to isolate the n term while keeping the equation balanced:

7n + 63 - 63 = 5 - 63

7n = -58

Now, divide each side of the equation by 7 to solve for n while keeping the equation balanced:

7n / 7 = -58 / 7

n = -58/7

The number is −58/7.

Hence , the number is -58/7 when a number is seven times its sum and 9 is 5.

As a result, after demonstrating that P(k) is true for any chosen value of k, we also demonstrated that P(k + 1) is true. According to the induction hypothesis, P(n) is true for all n ∈ Z+

To demonstrate that the mathematical proposition P(n) holds for all natural integers n = 1, 2, 3, 4,..., one uses the mathematical induction technique. It is frequently referred to as the induction principle in mathematics. We establish that P(1) holds in order to demonstrate a result P(n) using the mathematical induction technique. If P(1) is valid, we can assume that P(k) holds for some natural number k and use this assumption to demonstrate that P(k+1) is valid.

Let

P(n): 1×2 + 2×3+3×4+........+n(n+1)=[tex]\frac{n(n+1)(n+2)}{3}[/tex]

Putting n =1 we get

P(1):1×2 =2
