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
Answers
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.

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
Answers
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
Find the slope of the line that passes through the point (1,3) and (4,7)
Answers
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

The vertices of a polygon are (12, 24), (27, 24), (30, 12), and (6, 12). Find the area of the polygon.
Answers
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

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?
Answers
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
