The value of the maximum profit is 680

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The equation of the profit function is given as

P(x) = 230 + 30x - 0.5x^2

Differentiate the function

So, we have

P'(x) = 0 + 30 - x

Evaluate the like terms in the function

So, we have

P'(x) = 30 - x

Set the function to 0

So, we have

30 - x = 0

Evaluate

x = 30

Substitute x = 30 in the equation P(x) = 230 + 30x - 0.5x^2

So, we have

P(30) = 230 + 30 x 30 - 0.5 x 30^2

Evaluate

P(30) = 680

Rewrite as

Pmax = 680

Hence, the value of the maximum profit is 680

Answer:

The next 2 numbers would be 30 and 42

Step-by-step explanation:

If the last number in the sequence was 20, and the sequence started at 0 with a constant change, we know that since this constant change is +2 every time the input increases. If 12 + 8 was 20, the next number would be 30. If 20 + 10 is 30, then the next output will be 42, because 30 + 12 = 42.

The amount that Thang would pay in interest is $420 based on the loan of $2000 and simple interest of 7%

What is simple interest?

The simple interest on the loan is determined as the amount borrowed multiplied by the interest rate of 7% and as well multiplied by the number of years it takes for the loan to be repaid

Answer:

y = -x^2/10 + x/5 - 3/5

Step-by-step explanation:

The answer is D: just rearrange

It is given that P = principal, R = rate of interest and T = time

Formula to find compound interest is:

A = P(1 + R/100)^T

where A = amount received after n years

P = principal amount invested

R = rate of interest

T = time for which the amount is invested

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.

It is thought that Italy in the 17th century is where the concept of "interest on interest" or compound interest first appeared. It will accelerate the growth of a total more quickly than simple interest, which is solely calculated on the principal sum.

Money multiplies more quickly thanks to compounding, and the more compounding periods there are, the higher the compound interest will be.

In, mathematics a exponential function is inverse of logarithmic function. That means, we can easily convert the logarithmic function into exponential function and vice versa. The basic form of the logarithm function can be written as  [tex]a^x[/tex] .

where, a is the base of function

           x is the expression

Mathematically, if  [tex]log_aN = x[/tex] is an logarithmic function then, this can be converted to exponential function as  [tex]a^x = N[/tex].

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.

For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0. Similarly, the additive inverse of a − b is −(a − b) which can be simplified to b − a. The additive inverse of 2x − 3 is 3 − 2x, because 2x − 3 + 3 − 2x = 0.

The value of x that makes line m parallel to line l is 15.

When parallel lines are cut across by a transversal, angle relationships are formed.

The angle relationship form includes corresponding angles, alternate angles, vertically opposite angles etc.

Therefore, for line m to be parallel to line l,

5x - 10 + 8x - 5 = 180

Hence,

5x - 10 + 8x - 5 = 180

5x + 8x - 10 - 5 = 180

13x - 15 = 180

13x = 180 + 15

13x = 195

Therefore, divide both sides by 13

13x / 13 = 195 / 13

x = 15

Therefore, the value of x that makes line m parallel to line l is 15.

Step-by-step explanation:

Step-by-step explanation:

the standard deviation is first of all based on the squared differences of every data point to the mean value (squared, so that the direction of the difference does not matter, each number is positive).

this number is normalized to the number of data points (divided by "N").

and from that number we calculate the positive square root.

we take the square root to bring things back from the squared dimension of the data differences to the mean value and make it better understandable in size compared to the sizes of the data points. otherwise there is benefit to the squared variance (the whole thing without the last square root).

we have 15 data points (8 + 7).

first we need the mean value, which is the sum of all data points divided by the number of data points :

(7+10+5+5+6+3+5+5+6+5+5+5+9+3+5)/15 = 84/15 =

= 5.6

the standard variance is now the sum of the squares of the difference of each data point to the mean value.

e.g. the squared difference of 7 to 5.6 is

(7-5.6)² =(-1.4)² = 1.96

(1.96+19.36+0.36+0.36+0.16+5.76+0.36+0.36+0.16+0.36+0.36+0.36+11.56+5.76+0.36) / 15

= 47.6 / 15 = 3.173333333...

I Disagree with Peter, the explanation is down below.

Step-by-step explanation:

I disagree because to find the least common multiple or the LCM, you need to first list the first several multiples of each number. So, because the numbers are 4 and 6, I would write:

4 - 4, 8, 12, 16, 20, 24, 28, 32

6 - 6, 12, 18, 24 30, 36, 42, 48

The next step would be to find the same multiples in the list. If there are no same multiples, then I would keep on adding multiples.

If we look at the list, the first numbers that we see that are the same are 12 and 12.

12 would be the LCM, not 24.

If the two numbers were 24 and 12, then the LCM would have been 24, but in this case, the LCM is 12. So that is why I disagree.

Check the attached image above for solution

the complete table is:

zeros: x = -2, x = 0, x = 2.

Increasing: (-∞, -1.25) and (1.25, ∞)

Decreasing: (-1.25, 1.25)

End Behavior:   as x →∞, y →∞

                         as x → -∞, y→ -∞

Let's solve for the first function.

First, we want to find the zeros of the function. The zeros are the values of x such that the function becomes zero (intercepts the horizontal axis)

So we can see that the zeros are:

x = -2, x = 0, x = 2.

Now we want to see when the function is increasing. The function is increasing when it goes (reading from left to right) the function goes upwards.

The function is increasing on the intervals:

(-∞, -1.25) and (1.25, ∞)

And the function is decreasing between these two intervals:

(-1.25, 1.25)

Now we need to look at the end behavior.

When x tends to infinity, (right side) we can see that the function goes upwards, then:

as x →∞, y →∞

In the left side the function goes downwards, so:

as x → -∞, y→ -∞

Then the complete table is:

zeros: x = -2, x = 0, x = 2.

Increasing: (-∞, -1.25) and (1.25, ∞)

Decreasing: (-1.25, 1.25)

You want to know if baseline FH can be considered to be perpendicular to one of two congruent sides in isosceles triangle EFH.

The base angles of an isosceles triangle are congruent. That means they can never be right angles.

Base line FH cannot be perpendicular to side FE.

Additional comment

Angle E can be a right angle in isosceles triangle EFH, but neither of angles F or H can be.

Diagonal FH bisect angles EFG and EHG and the angle FEH is congruent to angle FGH.

Why is the triangle congruent?

1) EFGH is a rectangle.

The above statements is not true in general. EFGH is a quadrilateral with opposites sides are equal, it may be rectangle in some cases but it is not always be a rectangle.

2). EFGH has 4 congruent sides.The above statement is also false. EFGH has two opposite sides are congruent.

3). Diagonal FH bisect angles EFG and EHG.

The above statement is true. Triangle EFH and FGH both are isosceles triangles and hence they both have equal angles for the equal sides. Thus, it is true in all cases.

4). Diagonal FH is perpendicular to side Fe.

The above case is not true in general.

5). Angle FEH is congruent to angle FGH.
