The function y = x 2 - 10x + 31 has a ____
value of ____.
options for the first blank -
A. maximum
B. minimum
options for the second blank -
A. 31
B. 10
C. 6
D. 5
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.

The area of rectangle FGHK is 32.24 square centimeters.
What is rectangular shape?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.

Find the slope of the line that passes through the point (1,3) and (4,7)
Answer:
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
Slope = 4/3

Lenny bought a motorcycle. He paid 12.5% in tax. The tax added 1437.50 to the price of the motorcycle what was the price of the motorcycle not including the tax
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
Amount of motorcycle = $11,500

José makes lemonade for his family. He combines 1 tbs. Of drink mix, 3 cups of sugar and 1 gallon of water to make one pitcher of lemonade(1:3;1). How much of each ingredient would he need to make 4 pitchers of lemonade? What is the new ratio?
Answer:
1 : 3 : 1
Step-by-step explanation:
1 pitcher of lemonade:
Drink mix = 1 tbs
Cups of sugar = 3
Gallon of water = 1
Ratio = 1 : 3 : 1
How much of each ingredient would he need to make 4 pitchers of lemonade?
Multiply all ingredients by 4
Drink mix = 4 tbs
Cups of sugar = 12
Gallon of water = 4
What is the new ratio?
4 : 12 : 4
= 1 : 3 : 1
The new ratio = 1 : 3 : 1

How do I find the y intercept when all that is given is the x intercept?
Answer:
you dont, just make a vertical line where you plotted your point
Step-by-step explanation:
I am going to explain this as best as i can because i dont really remember how to do this
My teacher taught it to me as:
y is fly
so when you get an equation like this but with a y you will plot the dot on the y axis and make a horizontal line
x is dive
when you get an equation like this one you will plot the dot (exactly how you did it) and make a vertical line on that dot

The vertices of a polygon are (12, 24), (27, 24), (30, 12), and (6, 12). Find the area of the polygon.
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
Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a
viable solution if x represents the number of days that a library book is late and y represents the total fee?
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).
What are ordered pairs?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).

Harry paid $35 for a tie and $11 for a T-shirt. He gave the cashier a 100-dollar bill. How much change did he receive from the cashier?
helpp
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
Correct Answer: $54
