Use the function f(x) to answer the questions:
f(x) = 2x2 − 5x + 3
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
part A: x= 1 and x= 3/2
part B: minimum at (5/4, f(5/4))
Step-by-step explanation:
part A: factoring
0 = 2x^2 - 5x + 3
= (2x^2 - 2x)(-3x + 3)
= 2x(x - 1) -3(x-1)
= (2x - 3)(x - 1)
x= 1 and x= 3/2
part B: candidates test
find the derivative of the function.
f(x) = 2x^2 - 5x + 3
f'(x) = 4x -5
solve for critical numbers.
0 = 4x - 5
x = 5/4
candidates test by plugging in numbers into the derivative to see if that area is negative or pos.
f has a minimum at x = 5/4 because f' goes from neg to pos there. to find the coordinate for x = 5/4 just plug it into the original function to find f(5/4).
Part C: to draw the graph, I'd just plot the vertex coordinate that you solved for in part B, then I would plot the x intercepts that you solved for in part a, from there just draw a line throu the 3 points. (it should look like a U shape)

The area of a rectangle is 99 square units. Its width measures 11 units. Find the length
of its diagonal. Round to the nearest tenth of a unit.
Answer:
14.2
Step-by-step explanation:
11L=99
11 99
L=9
9^2 +11^2=c^2
81+121=c^2
sq root 202
14.212670
14.2=c
The area of a rectangle is 99 sq. units and if the width of the rectangle is 11 units then the length will be equal to 9 units.
What is a rectangle?The opposing faces of a quadrilateral were equal and identical, and all the angles are equal. Around us, there are numerous rectangle-shaped items. Two factors, length, and breadth define each rectangle shape.
As per the data provided by the question,
Area of the rectangle, a = 99 sq. units
width, w = 11 units
a = l × w
99 = l × 11
l = 99/11
l = 9 units.
Therefore, the length of the side is 9 units.

The length of the arc of semi circle is 15 cm calculate the area of the semi circle ?
Answer:
The area of the semi-circle is 35.8 cm².
Step-by-step explanation:
The length of the arc is given by:
[tex] s = r\theta [/tex] (1)
Where:
s: is the length of the arc of semi-circle = 15 cm
r: is the radius
θ: is the angle in radians
Since we need to calculate the area of the semi-circle, the angle is:
[tex] \theta = \frac{360}{2} = 180 = \pi [/tex]
From equation (1) we can find the radius:
[tex] r = \frac{s}{\theta} = \frac{15}{\pi} [/tex]
Now, the area of the semi-circle is:
[tex] A = \frac{\pi r^{2}}{2} = \frac{\pi (\frac{15}{\pi})^{2}}{2} = 35.8 cm^{2} [/tex]
Therefore, the area of the semi-circle is 35.8 cm².

Drag the label for the length of the sides of the triangle shown that would satisfy the following conditions: cos(B) = 9/41
tan (C) = 9/40 Not all choices will be needed
Trigonometry
Answers:
AB = 9 (vertical leg)AC = 40 (horizontal leg)BC = 41 (hypotenuse===============================================
Explanation:
We're told that
cos(B) = 9/41
Since the cosine ratio involves adjacent/hypotenuse, we can see that the adjacent side is 9 and the hypotenuse is 41. For angle B, the adjacent side is the leg closest to the angle in question. So that would be side AB.
Therefore, AB = 9 and BC = 41 are the adjacent and hypotenuse for reference angle B.
Apply the pythagorean theorem to solve 9^2+x^2 = 41^2, and you should get x = 40. This is the other leg of the triangle. Or you could note how tan(C) = 9/40 to imply that AC = 40 is the adjacent side for reference angle C.

Matt bowled three strings. His scores were 220, 166, and 181. What was his average for the three strings?
Answer:
189
Step-by-step explanation:
To find his average, we will find the mean. This means we will add 220+166+181 to get 567. When finding the mean we divide the answer but the total amount of addends. In our case we have 3 so we divide 567 by 3.
567 divided by 3 = 189

PLEASE HELP!! Step by step if possible
Answer:
r = 9
Step-by-step explanation:
[tex] In\: \odot O, [/tex] QP is tangent at point P and OP is radius.
[tex] \therefore OP\perp QP[/tex]
[tex] \therefore m\angle OPQ = 90\degree [/tex]
So, [tex] \triangle OPQ[/tex] is a right angled triangle. Hence, OQ will be its HYPOTENUSE such that OQ = r + 32
Now, by Pythagoras theorem:
[tex] OQ^2 = OP^2 + PQ^2 [/tex]
[tex] \therefore (r + 32)^2 = r^2 + (40)^2 [/tex]
[tex] \therefore\cancel {r^2} + 64r + 1024 = \cancel {r^2} + 1600 [/tex]
[tex] \therefore 64r = 1600-1024 [/tex]
[tex] \therefore 64r = 576 [/tex]
[tex] \therefore r = \frac{576}{64}[/tex]
[tex] \therefore r = 9[/tex]
