John invested the money at simple interest for 4.22 years.

We have,

Invested amount = $ 4500

Rate of interest = 5.5 %

Time = t years

Maturity value = $ 5545

So,

Total interest earned =  $ 5545 - $ 4500 = $ 1045

And,

Simple interest = (Principal × Rate × Time ) / 100

So, Using the mentioned formula,

1045 = ( 4500 × 5.5 × t ) /100

1045 = 45 × 5.5 × t

⇒

t = (1045) / (45 × 5.5)

⇒ t = 4.22 years

Therefore, John invested the money at simple interest for 4.22 years.

The equation that relates x and y is y = (1/3)x if the variables x and y vary directly and x = 18, y = 6.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

The question is incomplete.

The complete question is:

The variables x and y vary directly. Use the given values to write an equation that relates x and y. x = 18 y = 6

From the question:

y ∝ x

y = kx ..(1)

k is the constant of proportionality after removing the proportional sign.

Plug x = 18 and y = 6

6 = 18k

k = 1/3

Plug the value of k in the equation (1)

y = (1/3)x

Thus, the equation that relates x and y is y = (1/3)x if the variables x and y vary directly and x = 18, y = 6.

The correct definition of an angle is D: A shape formed by two intersecting lines from a common point.

A line segment is extended infinitely in both directions whereas a 'ray' is a line segment that has one endpoint and extends infinitely in the other direction.

Now, an 'angle' is formed by two rays having a common end-point.

As the angle has a common endpoint,

Therefore it is not possible to form an angle by intersecting two rays having different endpoints.

Hence, option D is correct.

Question 1

When a graph is shifted up or down we add or subtract the number of units it has shifted from the function.

From inspection of the graph, the vertex of function j(x) is (0, 2)

From inspection of the graph, the vertex of function j(x) + k is (0, -1)

Therefore, function j(x) has been translated 3 units down.

Therefore, the value of k is -3, since the function of the graph is j(x) -3

Question 2

When discussing the stretching of curves, it is usual to always refer to it as a "stretch" rather than a stretch or compression.  

If the scale factor a is 0 < a < 1 then the graph gets wider.  

If the scale factor a is a > 1 then the graph gets narrower (i.e. "compressed").

h(x) to h(2x) means that the function h(x) has been stretched horizontally by a factor of 1/2.  The other way to say this is that is have been compressed horizontally by a factor of 2.  In any case, as a > 1 the graph gets narrower.

Therefore, the vertex would stay in the same place but the curve would be narrower.

The answer for "?" is z+1.

Step-by-step explanation: In order to solve this I recommend comparing the two equations and expanding them as much as possible, like so.

[tex](\frac{2-z}{z} =\frac{(2-z)(?)}{z^2+z} )=(\frac{2-z}{z} =\frac{(2-z)(?)}{z(z+1)} )[/tex]

Once you have the equations expanded to their maximum you can see what was added to the right side of the equation and what you need to add to the numerator in this case to make the two equations equal.

[tex](\frac{2-z}{z} =\frac{(2-z)(z+1)}{z(z+1)} )[/tex]

*Note: You can also check the solution by plugging in a number for z and checking to see that both side equal. For example if z = 3.

[tex]\\\frac{2-3}{3} =-\frac{1}{3} \\\frac{(2-3)(3+1)}{3^2+3} =-\frac{1}{3}[/tex]

So, z+1 is the answer.

The given parameters are:

Since, the medication is eliminated from the blood; then it means that the function is an exponential decay function.

This is represented as:

d(n) = d(n - 1) * (1 - r)

Substitute r = 60%

d(n) = d(n - 1) * (1 - 60%)

Evaluate the difference

d(n) = d(n - 1) * 0.4

Evaluate the product

dn = 0.4d(n-1)

Answer:

[tex]\text{C.} \ \ \ {\left(\textit{AB}\right)}^{2} \ = \ \left(\textit{AC}\right)\left(\textit{AD}\right)[/tex]

Step-by-step explanation:

This problem uses the concept of the tangent-secant theorem which describes the relationship of the segments a secant line and a tangent line with the associated circle. This theorem is found as Proposition 36 in Book 3 of Euclid's Elements.

As shown in the figure attached below, segment AB (in blue) forms a tangent with the circle BCD and segment AD (in orange) is the secant where it intersects the circle at point C.

Furthermore, let two segments (in green) be drawn one from point C and point D.

To show that [tex]\triangle ABC[/tex] is similar to [tex]\triangle ADB[/tex], notice that both triangles share a common angle [tex]\angle BAC[/tex]. Additionally, by the alternate segment theorem, [tex]\angle ABC[/tex] is equal to [tex]\angle ADB[/tex]. Therefore, [tex]\angle ACB[/tex] is also equal to [tex]\angle ABD[/tex].

Hence, [tex]\triangle ABC[/tex] is indeed similar to [tex]\triangle ADB[/tex]. This implies the ratio of the sides of both triangles is the same. Particularly,

                                                  [tex]\displaystyle{\frac{AB}{AD} \ \ = \ \ \frac{AC}{AB}}[/tex].

Then, performing cross multiplication yields

                                             [tex]{\left(AB\right)}^{2} \ \ = \ \ \left(AC\right)\left(AD\right)[/tex].

Therefore, the product of the lengths of the secant segment and its external segment is equal to the square of the length of the tangent segment.

[tex] {x}^{2} + 5x + 6 = 0 \\ \\ {x}^{2} + 2x + 3x + 6 = 0 \\ \\ x(x + 2) + 3(x + 2) = 0 \\ \\ (x + 2)(x + 3) = 0 \\ \\ x + 2 = 0 \\ \\ x = - 2 \\ \\ x + 3 = 0 \\ \\ x = - 3.[/tex]

Answer:

y = (3/2)x - (1/2)

Step-by-step explanation:

The general structure of a line in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept. You have been given the value of "m" (3/2). To find the value of "b", you should plug "m" into the equation in addition to the "x" and "y" values from the given point (1,1)

(1,1) ----> x = 1, y = 1

m = 3/2

y = mx + b                                <----- Slope-intercept form

y = (3/2)x + b                            <----- Plug (3/2) into "m"

1 = (3/2)(1) + b                           <----- Plug values into "x" and "y" from point

1 = (3/2) + b                              <----- Multiply (3/2) and 1

(2/2) = (3/2) + b                        <----- Change 1 into common denominator

(-1/2) = b                                  <----- Subtract (3/2) from both sides

Because you now have values for both variables, you can construct your final equation.

y = (3/2)x - (1/2)
