EX #5: Based on the definition above, identify the following: A. Relative Maximum is __ where x = __ B. Relative Minimum is __ where x = __ C. Relative Minimum is __ where x = __
Answers
Based on the given graph, you can conclude:
A. Relative Maximum is f(x) = 1 where x = 2
(Because the relative maximum of a function is given by a point of the graph with a slope m = 0, but this point is not necessarily the absolute maximum. Furthermore, the concavity of the curve at this point is negative).
B. Relative minimum is f(x) = -8 where x = -3
C. Relative minimum is f(x) = 0 where x = 4
Both relative minima correspond to points in which the slope of the line is 0 and the concavity of the line is positive.

y= 10-4x identity the slope and y-intercept
Answers
Answer:
Step-by-step explanation:
First, graph the expression by making sure it goes through 10 on the y-axis and since it shows -4 that means for every 1 unit to the right the y coordinate moves 4 boxes down. (Your graph should look like a downwards slope)
Now, pick 2 points on your graph, ill pick (0, 10) and (1, 6)
Now, put these in point-slope form and you will get your slope
Point-Slope form
m=y2-y1/x2-x1
m= 10-6/0-1
m= 4/-1
m=-4
Also, you can just see that it's the slope by the graph by using rise over run.

What is mean by linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The regression line shows slope of 0.4 and has y - intercept as 24.029.
Now,
Since, The slope is positive, we find that when week increase temperature as;
The regression equation will be;
y = 24.029 + 0.4x
For week = 26
y = 24.029 + 0.4x
y = 24.029 + 0.4 × 26
y = 24.029 + 10.4
y = 34.429
Which is greater than 33.6.

Option C is correct.

Explanation
The equation of a circle with center (h, k) and a radius of r, is given as
(x - h)² + (y - k)² = r²
This can then be expanded to form the general form of the equation,
Ax² + By² + Cx + Dy + E = 0
For this question, where the center of the circle lies on the y-axis, the coordinates of the center of that circle will be (0, p)
where p is the y-coordinate of the center of the circle.
(x - h)² + (y - k)² = r²
(h, k) = (0, p)
h = 0, k = p
r = 3 units
(x - 0)² + (y - p)² = 3²
x² + y² - 2py + p² = 9
x² + y² -2py + p² - 9 = 0
Comparing this with Ax² + By² + Cx + Dy + E = 0
A = 1
B = 1
C = 0
D = -2p
E = p² - 9
We can easily see that only Option C has C = 0 and matches the equation of the circle described in the question.

The first step to solve this problem is to calculate the missing angle that has its vertex on P. The sum of the internal angles on every triangle is equal to 180 degrees, since we have the other two angles we can calculate the missing one as shown below:
[tex]\begin{gathered} 48+35+\measuredangle P=180 \\ 83+\measuredangle P=180 \\ \measuredangle P=180-83 \\ \measuredangle P=97 \end{gathered}[/tex]The angle is equal to 97 degrees. Now we know all the measurements of all the angles and sides of this triangle. When a triangle is rotated its measurements don't change, this means that if a side is equal to 2 before the rotation it should also be equal to 2 after the rotation. With this in mind we can say that:
The length of the side P'Q' is 9 units and the measurement of the angle P' is 97 degrees.
take the square root of both sides of the equation from part B ( n↑2−c↑2=0 ) and write the resulting equation. how can this equation be true, and what does this show about the relationship between the two triangles?

SOLUTION
From the question and the instructions given,

(you can only choose up to three btw)
Answers
The correct statement are;
⇒ One sweatshirt before tax costs $19.20.
Option A is true.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
Cost of sweatshirts for a store owner = $16
Profit percent = 20%
Sales tax = 7.5%
Now,
Profit price for a sweatshirts = 20% of $16
= 20/100 × 16
= 320 / 100
= $3.20
And, The sales tax price = 7.5% of 16
= 7.5 / 100 × 16
= 120 / 100
= $1.20
So, The cost of one sweatshirt before tax costs = $16 + $3.20
= $19.20
And, Sales tax for one sweatshirt = $1.20
So, Cost of sales tax for two sweatshirt = 2 × 1.20
= $2.40
And, Total cost of a sweatshirt = $16 + $3.20 + $1.20
= $20.4
So, Total cost of two sweatshirt = 2 × $20.4
= $40.8
Thus, The correct statement are;
⇒ One sweatshirt before tax costs $19.20.

540 people will be employed as medical assistants in the year 2013.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine the slope of the line :
m = (y₂ - y₁)/(x₂ -x₁ )
m = (560 - 359)/(10-0)
m = 20.1
This represents new assistants per year
So with your y-intercept of 359, your equation becomes
y = 20.1x + 359
Using this equation to estimate the number of people who will be employed as medical assistants in the year 2013.
Let y be the number of medical assistants (in thousands) employed in the country in the year x, where x = 0 represents 2004.
Substitute the value of x = 9 for the year 2013
y = 20.1(9) + 359
y = 180.90 + 359
y = 539.90 ≈ 540
Hence, 540 people will be employed as medical assistants in the year 2013.
