Find an exponential function that passes through (2,8) and (4,128)

The equation of the circle is (x + 7)^2 + (y + 5)^2 = 64.

The equation of a circle can be written in the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the center of the circle and r is the radius. Given that the center of the circle is (-7, -5) and the radius is 8, we can substitute these values into the equation: (x - (-7))^2 + (y - (-5))^2 = 8^2. Simplifying the equation, we get: (x + 7)^2 + (y + 5)^2 = 64. Therefore, the equation of the circle is (x + 7)^2 + (y + 5)^2 = 64.

The portion of gold in three bracelets that are shown. The bracelet that has a portion of gold is 0.65. The correct option is c.

Gold is actually a very soft metal. Rings constructed of pure gold would bend and disfigure over time. Other elements are added to strengthen the ring. 100% gold is far too soft and far from as durable as it should be.

Gold is a pure element. It is found in the earth's crust when making jewellery from gold, and some other metals like copper or silver is mixed with it.

True. Recursion is often necessary to solve certain types of problems that exhibit a recursive structure or require repeated subproblem solving.

Recursion is a programming technique where a function calls itself in its own definition. It allows for the decomposition of complex problems into smaller, more manageable subproblems that can be solved recursively. Recursion is particularly useful when problems exhibit a recursive structure, such as tree traversal, backtracking, or divide-and-conquer algorithms.

For example, problems like computing the factorial of a number, calculating Fibonacci numbers, or traversing a binary tree can be elegantly and efficiently solved using recursion. These problems can be broken down into smaller instances of the same problem until a base case is reached, and then the solutions are combined to solve the original problem.

However, it's worth noting that not all problems require recursion for their solution. There are alternative approaches, such as iterative loops or dynamic programming, which can be used depending on the problem's characteristics and requirements.

The in-order traversal of the tree represents the elements in ascending order, starting from the leftmost node to the rightmost node. In the case of the Fuli binary tree, the in-order traversal is **G L B A A I E T U**.

The Fuli binary tree can be constructed using the given post-order and pre-order traversals: Post-order traversal: **G L B V T AUIE**, Pre-order traversal: **E B G L A A T U**.

To construct the tree, we can use the following steps:

1. Identify the root of the tree: In the pre-order traversal, the first element is the root, so in this case, the root is **E**.

2. Locate the root in the post-order traversal: Since post-order traversal visits the left subtree first, we can find the root in the post-order traversal to divide it into left and right subtrees. In this case, we find **E** in the post-order traversal.

Recurse for left and right subtrees: Repeat steps 1-4 for the left and right subtrees using the divided pre-order and post-order traversals.

Using the above steps, we can construct the Fuli binary tree:

```

           E

Answer:

Graph A

Step-by-step explanation:

for edge

The value of angle a is 54⁰.

The value of angle b is 30⁰.

The value of angle c is 96⁰.

The value of angle a, b, c is calculated by applying intersecting chord theorem which states that the angle at tangent is half of the arc angle of the two intersecting chords.

m∠a = ¹/₂ x (108⁰) (interior angles of intersecting secants)

m∠a = 54⁰

The value of angle b is calculated as;

m∠b = ¹/₂ x (60⁰) (interior angles of intersecting secants)

m∠b = 30⁰

The value of angle c is calculated as;

adjacent angle to c = ¹/₂ x (108⁰ + 60⁰) (interior angles of intersecting secants)

adjacent angle to c = 84⁰

angle c = 180 - 84⁰ (sum of angles on a straight line)

angle c = 96⁰

The two minus signs "cancel." The product of any set of numbers with an even number of minus signs will be positive.

Answer:

14 $1 coin

12 quarter coin

Step-by-step explanation:

Let :

x = $1 dollar coin

y = $0.25 (1 quarter) coin

x + y = 26 - - - (1)

1x + 0.25y = 17 - - - - (2)

From (1) :

x = 26 - y

Put x = 26 - y in (2)

1(26 - y) + 0.25y = 17

26 - y + 0.25y = 17

-y + 0.25y = 17 - 26

-0.75y = - 9

Divide both sides by - 0.75

-0.75y /- 0.75 = - 9 / - 0.75

y = 12

Put y = 12 in (1)

x = 26 - 12

x = 14

divide by 4 on every term

y = -1/4x - 8

therefore the slope is -1/4 and y intercept is -8

A graph of the solution (4, 4) for the system of linear equations is shown in the image attached below.

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).

In this context, we would replace the y-value of the first equation 4x - 2y = 8 with zero (0) as follows;

4x - 2(0) = 8

4x = 8

x = 2 ⇒ (2, 0).

For the y-intercept of the first equation 4x - 2y = 8, we would substitute the x-value with zero (0) as follows;

4(0) - 2y = 8

2y = -8

y = -4 ⇒ (0, -4).

For the y-intercept of the first equation y = 3x/2 - 2, we would substitute the x-value with zero (0) as follows;

y = 3(0)/2 - 2

y = -2 ⇒ (0, -2).

Based on the graph shown in the image attached below, we can logically deduce that the solution to this system of linear equations is at the point of intersection of the lines on the graph representing each of them, which lies in Quadrant I and it is equal to the ordered pair (4, 4).

Annabelle supplied 121.35 pounds of shrimp, Curly Q supplied 96.9 pounds of shrimp, and Slojoe supplied 72.81 pounds of shrimp.

The three shrimp boats, Annabelle, Curly Q, and Slojoe, collectively supplied 242.7 pounds of shrimp to Hudson's, 217 pounds to Captain J's, and 159.3 pounds to Mainstreet.

Annabelle supplied 50% of its catch to Hudson's, 20% to Captain J's, and 30% to Mainstreet. Therefore, Annabelle supplied: (242.7 x 0.5) = 121.35 pounds of shrimp to Hudson's, (217 x 0.2) = 43.4 pounds of shrimp to Captain J's and (159.3 x 0.3) = 47.79 pounds of shrimp to Mainstreet.

In total, Annabelle supplied = 121.35 + 43.4 + 47.79 = 212.54

Curly Q supplied 40% of its catch to Hudson's, 40% to Captain J's, and 20% to Mainstreet. Therefore, Curly Q supplied (242.7 x 0.4) = 96.9 pounds of shrimp to Hudson's, (217 x 0.4) = 86.8 pounds of shrimp to Captain J's, and               (159.3 x 0.2) = 31.86 pounds of shrimp to Mainstreet.

Step-by-step explanation: just took it

The expression which represents the profit is 33x + 390, the correct option is D.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that;

The polynomial= 2x3 + 30x – 130

The cost, in dollars, of producing the skateboard= 2x3 – 3x – 520.

Now,

To find the expression that represents the profit, we need to subtract the cost from the revenue. So, we have:

profit = revenue - cost

profit = (2x^3 + 30x - 130) - (2x^3 - 3x - 520)

profit = 2x^3 + 30x - 130 - 2x^3 + 3x + 520

profit = 33x + 390

Therefore, the expression will be 33x + 390.
