The percentage error for each of the given situations are:

1) 23%

2) 21%

3) 11%

4) 16.67%

5) 43%

The formula for percent error is:

Percentage Error = ((Actual Number – Estimated Number)/ Estimated number) * 100%

1) Estimated Number = 2310

Actual Number = 3000

Thus:

Percent Error = (3000 - 2310)/3000 * 100%

Percent error = 23%

2) Estimated Number = 17600

Actual Number = 21300

Thus:

Percent Error = (21300 - 17600)/17600 * 100%

= 21%

3) Estimated Number = 4.5

Actual Number = 4

Thus:

Percent Error = (4 - 4.5)/4.5 * 100%

= 11%

4) Estimated Number = 15000

Actual Number = 12500

Thus:

Percent Error = (12500 - 15000)/15000 * 100%

= 16.67%

5) Estimated Number = 350

Actual Number = 200

Thus:

Percent Error = (200 - 350)/350 * 100%

= 43%

The value of m in terms of other variables of the right angle triangle is: m = √(p² - n²)

Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.

The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).

Pythagoras is in the form of;

a² + b² = c²

However, it can also be written in the form of c² = a² + b²

From the given triangle, we can write as:

p² = m² + n²

m² = p² - n²

The task here is to determined where the table given is a function. Thus we can state that the above table is NOT a function. This is called Non-Function Relation.

The table given above is suggestive of the relationship between the values of x and y given.

It may be inferred that x values are the input values while the y values are the output.

So the criteria for the values on the table to constitute a function is that each input value (x) must be associated with only one value of y.

From the table, it is clear to see that this rule if violated. You have the x value (-1) being associated with the y values of 2 and 4 respectively, hence, it is proper to conclude that the table is NOT  a function.

The maximum of 1,159 m/s occurs when t = 7, and the minimum of 16 m/s occurs when t = 6.

It should be noted that upon deriving v(t), an equation of 12t² - 96t + 144 is produced. Subsequently, v'(t) must be set to zero, resulting in a quadratic equation of 12t² - 96t + 144 = 0, requiring division of both sides by 12 to produce t² - 8t + 12 = 0.

The quadratic can now be factored to obtain (t - 2)(t - 6) = 0, indicating that critical points lie on the values t = 2 and t = 6.

After calculating these values— v(1) = 100 m/s, v(2) = 64 m/s, v(6) = 16 m/s and v(7) = 1159 m/s—it is clear that the maximum of 1,159 m/s occurs when t = 7, and the minimum of 16 m/s occurs when t = 6.

Answer:

[tex]\frac{-11}{4} (x + 2)^2 + 6.[/tex]

Step-by-step explanation:

As we know that

The standard equation of a parabola with vertex at point (h,k) is given by:

[tex]y = a(x-h)^2 + k[/tex]

where (h,k) is the vertex

and "a" is a coefficient that determines the direction and shape of the parabola.

We know that the vertex of our parabola is (-2, 6),

so we can substitute those values into the equation to get:

[tex]y = a(x + 2)^2 + 6[/tex]

Now finding a.

Since the parabola passes through point (-4, -5). Substituting these coordinates into the equation, we get:

-5 = a(-4 + 2)^2 + 6

-5 =a(-2)^2+6

-5=4a +6

-5-6=4a

4a=-11

a =- 11/4

Substituting the value of an equation second, we get

[tex]\frac{-11}{4} (x + 2)^2 + 6.[/tex]

Therefore, the equation of the parabola with a vertex at (-2, 6) and passing through (-4, -5) is y =

[tex] \frac{-11}{4} (x + 2)^2 + 6[/tex]

Answer:

[tex]y=-\dfrac{11}{4}(x+2)^2+6[/tex]

Step-by-step explanation:

The vertex form of a parabola is:

[tex]\boxed{y=a(x-h)^2+k}[/tex]

where:

Given the vertex is at (-2, 6), substitute h = -2 and k = 6 into the equation:

[tex]y=a(x-(-2))^2+6[/tex]

[tex]y=a(x+2)^2+6[/tex]

To find the value of a, substitute the point (-4, -5) into the equation and solve for a:

[tex]\begin{aligned}-5&=a(-4+2)^2+6\\-5&=a(-2)^2+6\\-5&=4a+6\\-5-6&=4a+6-6\\-11&=4a\\\dfrac{-11}{4}&=\dfrac{4a}{4}\\-\dfrac{11}{4}&=a\\a&=-\dfrac{11}{4}\end{aligned}[/tex]

Substitute the found value of a back into the equation:

[tex]y=-\dfrac{11}{4}(x+2)^2+6[/tex]

Therefore, the equation of a parabola with a vertex at (-2, 6) and that passes through the point (-4, -5) is:

[tex]\boxed{y=-\dfrac{11}{4}(x+2)^2+6}[/tex]

The minimum selling price per brownie to make a daily profit of at least $420 is $1.30.

Given that: A baker produces 400 brownies a day at a cost of 25 cents per brownie.

Let's begin by calculating the total cost of producing 400 brownies a day:

Cost per brownie = 25 cents = 0.25 dollars

Total cost = 400 × 0.25 = 100 dollars

To make a daily profit of at least $420, the total revenue should be:

Total revenue = Total cost + Minimum profit

Total revenue = 100 + 420 = 520 dollars

The minimum selling price per brownie to achieve this revenue can be calculated as:

Selling price per brownie = Total revenue / Number of brownies produced

Selling price per brownie = 520 / 400

Selling price per brownie = 1.3 dollars

Therefore, the minimum selling price is $1.30 per brownies.

Let's denote the number of bankers who manage only personal loans as P and the number of bankers who manage only business loans as B. Then, we can use the following information to form equations:

There are 20 bankers who manage personal loans, which means P + 3 bankers in total manage personal loans.

There are 25 bankers who manage business loans, which means B + 3 bankers in total manage business loans.

The bank has a total of X bankers.

Using these equations, we can solve for X as follows:

P + 3 = 20 (equation 1)

B + 3 = 25 (equation 2)

P + B + 3 = X (equation 3)

Solving equation 1 for P, we get P = 17.

Solving equation 2 for B, we get B = 12.

Substituting P = 17 and B = 22 into equation 3, we get:
