Answer:

Option B. minimum is correct for the first blank

Option C. 6 is correct for second blank.

Step-by-step explanation:

In order to find the maxima or minima of a function, we have to take the first derivative and then put it equal to zero to find the critical values.

Given function is:

[tex]f(x) = x^2-10x+31[/tex]

Taking first derivative

[tex]f'(x) = 2x-10[/tex]

Now the first derivative has to be put equal to zero to find the critical value

[tex]2x-10 = 0\\2x = 10\\x = \frac{10}{2} = 5[/tex]

The function has only one critical value which is 5.

Taking 2nd derivative

[tex]f''(x) =2[/tex]

[tex]f''(5) = 2[/tex]

As the value of 2nd derivative is positive for the critical value 5, this means that the function has a minimum value at x = 5

The value can be found out by putting x=5 in the function

[tex]f(5) = (5)^2-10(5)+31\\=25-50+31\\=6[/tex]

Hence,

The function y = x 2 - 10x + 31 has a minimum  value of 6

Hence,

Option B. minimum is correct for the first blank

Option C. 6 is correct for second blank.

Answer:

(X,$0.30)

Step-by-step explanation:

X represents the number of days past due and the Y which is 0.30 represents the additional cost per day

The required ordered pair is (x,0.30x).

In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b. (In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.)

Now, it is given that

late payment charges at midnight = $0.30

x is the number of days that a library book is late

y is the the total fee

So, penality charge in x days =  number of days*late payment charges

penality charge in x days =  $0.30x

Now, Let us suppose that the total penalty charge in x days is y ,

Hence

y = 0.30x

which makes a function that represents a relation between penalty imposed and the number of days for which it was delayed.

Hence the required ordered pair is (x,0.30x).

Step-by-step explanation:

Answer:

Amount of motorcycle = $11,500

Step-by-step explanation:

Given:

Tax rate = 12.5 % = 0.125

Amount of tax = $1,437.50

Find:

Amount of motorcycle

Computation:

Amount of motorcycle = [Amount of tax ] / Tax rate

Amount of motorcycle = [1,437.50] / 0.125

Answer:

234

Step-by-step explanation:

A(12, 24), B(27, 24), C(30, 12), and D(6, 12)

A and B have same y value of 24, AB // x axis

C and D have same y value of 12, CD // x axis

AB // CD

AB distance = 27 - 12 = 15

CD length = 30 - 6 = 24

AB ≠ CD      ABCD is a trapezoid

Area of trapezoid: (upper base + lower base) x height   / 2

height = y difference of A and D or B and C  24 -12 = 12

Area = (15 + 24) x 12  / 2 = 39 x 12  / 2 = 234

Answer:

54

Step-by-step explanation: you add 35 and 11 together then subtract 100 by the number you got to get the anwser

Answer:

The answer is $54

Step-by-step explanation:

Since Harry paid $35 for a tie and $11 for a T-shirt,he paid $46, if he gave the cashier $100, then he would get $56 back.

Step 1: Add how much he paid for the tie and T-shirt

$35 + $11 = $46

Step 2:Subtract 100 from the sum of the tie and T-shirt

$100 - $46 = $54

Step 3:Check the solution to make sure it's right

If 100 - 46 = 54, then 54 + 46 = 100

If 35 + 11 = 46, then 46 - 35 = 11

The area of rectangle FGHK is 32.24 square centimeters.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:

FGHK is a rectangle.

And length = 4 cm.

The area of the rectangle, in diagonal d terms,

= the length x √(d² - l²)

= 4 x √(9² - 4²)

= 4 x 8.06

= 32.24 square centimeters.

Therefore, 32.24 square centimeters are the area of the rectangle.

4/3

Step-by-step explanation:

To find the slope from two points, we need to label these coordinates.

(1, 3) will be coordinates 1, and (4, 7) will be coordinates 2.

(Basically 1 = x1, 3 = y1, 4 = x2, 7 = y2)

To find slope, we need to solve this equation:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug the numbers into the equation.

[tex]\frac{7-3}{4-1}[/tex]

Solve. 4/3
