Answer:

\large \boxed{\text{\$15.22/yr}}

Step-by-step explanation:

The average rate of change is the change in weekly earnings divided by the change in time.

1. Change in earnings  

Change in earnings = $549 - $412 = $137

2. Change in time

Change in time = 1999 - 1990 = 9 years

3. Average rate of change

\begin{array}{rcl}\text{Average rate of change} &= &\dfrac{\text{change in weekly earnings}}{\text{change in time}}\\\\&= &\dfrac{\text{\$137}}{\text{9 yr}}\\\\& = & \textbf{\$15.22/yr}\\\end{array}\\\text{The average rate of change in weekly earnings was $\large \boxed{\textbf{\$15.22/yr}}$}

Answer:

Let D represent the average rate of change between 1990 and 1999

D ≈ 33%

Step-by-step explanation:

412+412×(D÷100 )= 549

⇔ 412×(D÷100) = 549 - 412

⇔ 412×(D÷100) = 137

⇔ D÷100 = 137÷412

⇔ D÷100 = 0.332524271845

⇔ D = 33.2524271845.

Joshua finds the perimeter of the following composite figure composed of a square and right triangle so that a braid may be cut
Bumek [7]

The perimeter of a shape is the sum of its side lengths.

<em>Joshua miscalculated the third length of the triangle</em>

First, we calculate the third length (x) of the triangle.

Because the triangle is right-angled, we can make use of Pythagoras.

So we have:

x^2 = 7^2 + 7^2

x^2 = 2(7^2)

Take square roots of both sides

x = \sqrt{2(7^2)

x = 7\sqrt{2

The other shape in the figure is a square.

So, the perimeter (P) is

P = 7 + x + x + x + 7 ---- i.e. the sum of the visible lengths

So, we have:

P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7

Evaluate like terms:

P = 14 + 21\sqrt2

Hence, Joshua's error is that:

<em>He miscalculated the third length of the triangle</em>

Identify the domain of the exponential function shown in the following graph :
Vinil7 [7]

Answer:

The domain of this exponential function is (all real numbers).

Step-by-step explanation:

The domain is all real numbers because according to the x-axis the function passes through all numbers the negative and positive. As you see the graph is continuous which means it will keep on going.

I hope this helps!

We are required to find the cost of each cherry tree and rose bushes.

The cost of each cherry tree, x is $8 and the cost of each rose bushes, y is $12

let

<em>cost of each cherry tree = x</em>

<em>cost of each cherry tree = xcost of each rose bushes = y</em>

The equation:

7x + 11y = 188 (1)

13x + 11y = 236 (2)

Subtract (1) from (2) to eliminate y

13x - 7x = 236 - 188

6x = 48

divide both sides by 6

x = 48 / 6

x = 8

substitute x = 8 into (1)

7x + 11y = 188 (1)

7(8) + 11y = 188

56 + 11y = 188

11y = 188 - 56

11y = 132

divide both sides by 11

y = 132 / 11

y = 12

Therefore, the cost of each cherry tree, x is $8 and the cost of each rose bushes, y is $12
