Answer:
a) x = {-1, 3, 4}
b) (0.472, 13.128)
c) (3.528, -1.128)
d) x < 0.472 U x > 3.528
e) 0.472 < x < 3.528
Step-by-step explanation:
This is a cubic (odd degree) function with a positive leading coefficient, so it will be increasing until the first turning point, and after the last turning point. It will be decreasing between the turning points.
a) A graph shows the zeros to be x = -1, x = 3, x = 4.
b) A graph shows the local maximum to be approximately (0.472, 13.128). The x-coordinate of this point is exactly 2-√(7/3).
c) The local minimum is about (3.528, -1.128). Its x-coordinate is exactly 2+√(7/3).
d) As stated above, the increasing intervals are (-∞, 0.428) ∪ (3.528, ∞).
e) The decreasing interval is (0.428, 3.528).

Additional comments
The sum of odd-degree term coefficients is the same as the sum of coefficients of even-degree terms, so you know one of the roots is -1. Factoring that out gives the quadratic x^2 -7x +12 = (x -3)(x -4), so the other two roots are 3 and 4.
The derivative is 3x^2 -12x +5 = 3(x -2)^2 -7, so its roots (turning points of f(x)) are 2±√(7/3).
I find a graphing calculator can show me the roots and turning points easily.
imagine that you are in an argument with a friend about the size of the slice of pizza you were both served. your friend says that it was unfair because you got a bigger piece what information would you need to know about each slice of pizza in order to calculate which one had a larger area? explain.
We need to know the Angle subtended by the slice at the center of the pizza i.e. Θ, Radius of the pizza i.e. r about each slice of pizza in order to calculate which one had a larger area.
What is area ?Area is defined as the quantity that expresses the extent of a region on the plane or on a curved surface.
Area of sector [tex]=\frac{\theta}{360}\pi r^2[/tex]
Here,
Θ = angle subtended by the arc at the center.
We have,

Answer:
58
Step-by-step explanation:
The angles inside a triangle always sum to 180°. We already have a 32° angle and a 90° - totalling 122° - and when we add x°, we'd like the sum to be 180°. So x must be 180 - 122 = 58.
Answer:
58
Step-by-step explanation:
The total should be 180 degrees. We know the the top angle is 32 degrees and the bottom left is 90 degrees because it has a square there. So 32+90=122. If we subtract 122 from 180 we are left with 58 degrees so x=58

Volume of a cone formula:
V = πr²(h/3)
D/2 = r
10/2 = r
r = 5
393 = (3.14)5²(h/3)
393 = 78.5(h/3)
h = 15.02

Answer:
x = 25
Step-by-step explanation:
By the property,
Equal chords subtend equal angles at the center of the circle. Therefore, measures of arcs having equal central angles will be equal.
2x + 4x + (3x + 30) + (3x + 30) = 360°
(2x + 4x + 3x + 3x) + (30 + 30) = 360
12x + 60 = 360
12x = 300
x = [tex]\frac{300}{12}[/tex]
x = 25

What is the volume of a cylinder, in cubic centimeters, with a height of 15 centimeters
and a base diameter of 6 centimeters? Round to the nearest tenths place
Answer:
The volume of the Cylinder is 424.1 Cubuc centimeter.
Step-by-step explanation:
The formula to find the volume of a cylinder is,
[tex]v = \pi \times {r}^{2} \times h[/tex]
Where V is the volume, R is the radius And H is the hight of the Cylinder.
So, in this case, you have
[tex]r = 3cm[/tex]
Because
[tex]radius \: = \frac{diameter}{2} [/tex]
[tex]h = 15cm[/tex]
[tex]v = \pi \times {r}^{2} \times h[/tex]
[tex]v = \pi \times (3cm)^{2} \times 15cm[/tex]
[tex]v = \pi \times 9cm^{2} \times 15cm[/tex]
[tex]v = 424.cm ^{3} [/tex]
Therefor, the volume of the Cylinder is 424.1 Cubic centimeter.

Find the distance between the points (9, 8) and (5, 3).
Write your answer as a whole number or a fully simplified radical expression. Do not round,
___ unit
Answer:
6 or 6.4
Step-by-step explanation:
Point 1
(xA,yA)= (9, 8)
Point
(xB,yB) = (5, 3)
Formula :
Distance between two points =
√(xB−xA)2+(yB−yA)2
Solution :
Distance between two points =
√(5−9)2+(3−8)2= √(−4)2+(−5)2= √16+25= √41 = 6.4031
Distance between points (9, 8) and (5, 3) is 6.4031

Determine whether x=3, x=4, or x=5 is the solution.
42–x=37
Answer: x=5
Explanation:
Rearrange the equation
42-x=37 is the same as 37+x=42
Isolate the variable x by subtracting 37 from both sides
37-37 cancels out and 42-37 is 5
X=5 is what you’re left with
I need help figuring this problem out
Answer:
1. 28
2. 53
Step-by-step explanation:
1. The angle CFD is a straight line, this means that the measure is 180. This means, using the angle addition postulate, you can set up the equation [tex]180=x+152[/tex]. Then, subtract 152 from both sides to get [tex]x=28[/tex].
2. The question states that the two angles are complementary. This means that they summate to 90 degrees. So using the angle addition postulate again, you can set up the equation, [tex]90=x+37[/tex]. Finally, subtract 37 from both sides to get [tex]x=53[/tex].
If the company were to issue an annual zero-coupon bond with a maturity of 2 years and a par value of $1,000, what would be the arbitrage-free price of that bond?
Answer:
Step-by-step explanation:
[tex]\text{here is the missing text:} \\ \\ \text{ Suppose a company issues an annual coupon bond with a maturity of 2 years,} \\ \\ \text{ price of $950 \ par \ value \ of $1,000, and coupon rate of 5\% They also issue an}[/tex]
[tex]\text{ annual zero-coupon bond with a maturity of 1 year, price of $900, \ and \ par \ value \ of \ $1,000.}[/tex]
[tex]\text{To determine the 1-year spot rate using the 1-year zero bond.} \\ \\ FV = PV \times (1 + S_1) \\ \\ 1+ S_1 = \dfrac{FV}{PV} \\ \\ 1 + S_1 = \dfrac{1000}{900} \\ \\ S_1 = 11.11\%[/tex]
[tex]\text{PV of the 2-year bond = 950} \\ \\ Annual coupon = 1000 \times 5\% = \$50 \\ \\ \\ 950 = \dfrac{50}{(1+S_1) }+ \dfrac{(50+1000)}{(1+S_2)^2} \\ \\ 950 = \dfrac{50}{1.1111}+ \dfrac{1050}{(1+S_2)^2} \\ \\ \dfrac{1050}{(1+S_2)^2}=950 -45\\ \\ \dfrac{1050}{(1+S_2)^2}=905 \\ \\ (1+S_2)^2 = \dfrac{1050}{905} \\ \\ 1 + S_2= \sqrt{(1.16022)} \\ \\ S_2 = 7.714\%[/tex]
[tex]\text{the arbitrage-free price of the 2-year bond}= \dfrac{1000}{(1+0.07714)^2} \\ \\ = \mathbf{\$861.90}[/tex]
