Answer:
14
Step-by-step explanation:
f'(2) = 2y + 10
f'(2) = 2(2) + 10
= 4 + 10
= 14
»f(y) = y² + 10y + 21
Find f'(y) in f(y)»f'(y) = 2y + 10 + 0
»f'(y) = 2y + 10
Find f'(2) in f(y)»f'(2) = 2(2) + 10
»f'(2) = 4 + 10
»f'(2) = 14✅

A quality control manager at an auto plant measures the paint thickness on newly painted cars. A certain part that they paint has a mean thickness of 2mm with a standard deviation of 0.8mm.
The manager takes a daily random sample of thickness measurements from 100 randomly chosen points on these parts and calculates the sample mean thickness
-x from each sample. We can assume that the points in each sample are independent.
What will be the shape of the sampling distribution of -x?
Answer:
Approximately Normal
Step-by-step explanation:
Even though we don't know the shape of the population distribution of thicknesses, the sampling distribution of -x will be approximately normal since the sample size is large (n=100≥30).
Use the following to determine your monthly balance for a monthly net income of $2,700. Monthly Expenses of: Fixed $625; living $1,200; Annual monthly $625 *
The net income is the difference between the gross income and the total expenses
The net monthly balance is $1975
How to determine the net balanceThe monthly income is given as:
Income = $2700
The expenses are given as:
Fixed $625;
Living $1,200 (Annual)
The living expense is given per annual.
So, we start by calculating the monthly living expense
This gives
Living =$1200/12
Living = $100
The net balance is then calculated as:
Net = Income - Living - Fixed
This gives
Net = $2700 - $100 - $625
Net = $1975
Hence, the net income is $1975

What is an approximate solution to this equation? 4/x-5=√x+3+2
A. 3.73
B. 5.81
C. 4.97
D. -0.80
The approximate solution to the equation [tex]\dfrac{4}{x - 5} = \sqrt{x + 3} +2[/tex] found using
the Newton-Raphson method is option B.
B. 5.81
How can the Newton-Raphson method be used?The given function is presented as follows;
[tex]\dfrac{4}{x - 5} = \mathbf{ \sqrt{x + 3} +2}[/tex]
Which gives;
[tex]\dfrac{4}{x - 5} -2= \sqrt{x + 3}[/tex]
[tex]\left(\dfrac{14-2\cdot x}{x-5} \right)^2 = \sqrt{x+3} ^2 = x+3[/tex]
[tex]\mathbf{\dfrac{4\cdot x^2 - 56 \cdot x + 196}{x^2-10\cdot x + 25}} = x + 3[/tex]
Therefore;
[tex]\mathbf{\dfrac{4\cdot x^2 - 56 \cdot x + 196}{x^2-10\cdot x + 25} - (x + 3)} = 0[/tex]
[tex]\dfrac{- x^3 + 11 \cdot x^2 - 51 \cdot x + 121}{x^2-10\cdot x + 25} = 0[/tex]
x³ - 11·x² + 51·x - 121 = 0
Using the Newton Raphson method, with x₀ = 6, we have;
[tex]x_1 = x_0- \dfrac{x^3 - 11 \cdot x^2 + 51 \cdot x - 121}{3 \cdot x^2 - 22 \cdot x + 51}[/tex]
Which gives;
[tex]x_1 = 6- \dfrac{6^3 - 11 \times 6^2 + 51 \times 6 - 121}{3 \times 6^2 - 22 \times 6 + 51} \approx \mathbf{ 5.81}[/tex]

Answer:
the following points would make a trapezoid
Answer:
The polygon is a rectangle
Explanation
If you subtract the y-values of the coordinates that have the same x-values, you will get one of the sides of polygon. Then, if you subtract the x-values of the coordinates that have the same y-values, you will get the other side of the polygon. Since this has only 4, sides with a right angle. It must be a rectangle or square. but seeing that the sides are different, the polygon must be a rectangle

A
Step-by-step explanation:
Because the average is already 49.333 If you rounded by tenth then 49.3 because.
Tenth is the 1rst number behind the decimal so the three looks to it's other neighbor hundredths because hundredths=second number behind decimal so 3 goes over to 3 and asks for help.
Because it is 4 and below you keep it low so 3 can't go up so your answer is 49.3 rounded to nearest tenth.

Answer:
1. $34.30
2. $9.60
3. $135.30
4. $8.25
Step-by-step explanation:
Answer:
1. $14.70
2. $1.60
3. $135.30
4. $8.25
Step-by-step explanation:
1. Convert percentage to decimal:
30% = 30/100 = 0.3
So 30% of $49 = 0.3 x 49 = 14.7
Therefore, a discount of 30% = a discount of $14.70
2. Convert percentage to decimal:
20% = 20/100 = 0.2
So 20% of $8 = 0.2 x 8 = 1.6
Therefore, the 20% tip = $1.60
3. Convert percentage to decimal:
20% = 20/100 = 0.2
So 20% of $112.75 = 0.2 x 112.75 = 22.55
Therefore, total cost with the tip = 112.75 + 22.55 = $135.3
4. If a discount of 45% is applied, the new cost of the shirt will be 55% of its original price (as 100% - 45% = 55%)
Convert percentage to decimal:
55% = 55/100 = 0.55
So 55% of $15 = 0.55 x 15 = 8.25

Complete the two-column proof below. The ‘reasons’ are already given so only the mathematical ‘statements’ need to be completed.
Given: A and B are complementary angles. B and C are complementary angles.
Prove A ~= C
===================================================
Further explanation:
You start with what we're given, which is the two statements that
A and B are complementary angles. B and C are complementary angles.We literally copy/paste this into the first box for the "Statements"
From there, we can say A+B = 90 and B+C = 90 due to the definition of what "complementary" means. Complementary angles always add to 90 degrees.
Since A+B = 90 and B+C = 90, the left hand sides can be set equal to one another through the substitution rule. That's how we end up with A+B = B+C on step 3.
Next, we subtract B from both sides to go from A+B = B+C to A = C.
For the last step, we do a bit of a notation change, and the proof is wrapped up.

What is the slope of the line that passes through the points (-7,-8) and (-5,-6) write your answer in simplest form
y=x-1
When x=0, y = -1
When y=0, x = 1
delta y over delta x = 1/1 which means the slope is 1
Answer:
Slope is equal to 1.
Step-by-step explanation:
(-7, -8) --> (x1, y1)
(-5, -6) --> (x2, y2)
[tex]slope \: = \frac{y2 - y1 }{x2 - x1} \\ slope \: = \frac{ - 6 -( - 8) }{ - 5 - ( - 7)} \\ slope \: = \frac{ - 6 + 8}{ - 5 + 7} \\ slope \: = \frac{2}{2} \\ slope = 1[/tex]

Answer:
145 degrees
Step-by-step explanation:
Linear pairs. 180-35=145
Answer:
145 degrees
Step-by-step explanation:
Angle H is next to what I assume is angle G. If you add those two together they will equal 180 degrees because they are supplementary angles. So your equation is
H= 180-35
Which equals 145

Answer:
$22.75
Step-by-step explanation:
We know that Mac used 7 sheets that cost $3.25 each. Our goal is to find the total cost that the sheets were altogether.To find this, we need to multiply the number of sheets by the cost.This will be 7 • $3.25, which will get us $22.75If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

10. Find the length of each side of a triangle if the perimeter is 73 in. The length of the second side is twice the length of the first side and the length of the third side is five more than thee length of the first side.
Answer:
Step-by-step explanation:
Given the Perimeter of a triangle is 73
Let the first side be x
second side = 2x
third side = x+5
PERIMETER OF A TRIANGLE = SUM OF ALL SIDES
73=X+2X+X+5
73=4X+5
73-5=4X+5-5
68=4X
68/4=4X/4
17=X
THIS IMPLISE THAT FIRST SIDE IS X = 17
SECOND SIDE IS 2X= 2*17=34
THIRD SIDE IS X+5=17+5=22
