A school district currently has 12,000 students. Based on declining enrollment figures, the number of students in the school district is expected to decline by 5% each year. Which of the following functions represents the number of students,
S
, in the school district after
n
years?
Answer:
Step-by-step explanation:
[tex]\text{Since the enrollment decreases every year this is exponential decay of the form}\\ \\ F=Ir^t\\ \\ F=12000(1-.05)^t\\ \\ S(n)=12000(0.95)^n[/tex]
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.

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.
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].

a5=20
a3=20
a4=15
a2=15
as=94
Step-by-step explanation:
it is asking for each of the areas
I'm assuming As stands for areas summed
Answer:
a1=a6=lb=3×4=12
a5=a3=lb=5×3=15
a4=a2=lb=5×4=20
As=12×2+15×2+20×2=a1+a2+a3+a4+a5+a6=24+30+40= 94
Need help please I'm not sure if I'm right
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

Round 5,784 to the nearest ten
Answer:
I think you might mean 5.784 and if that is the case it would be 5.8
Step-by-step explanation:
5.8 would be the answer because 8 is closer to 10 than 0 so 7 would be rounded up to 8

Pizzeria Napoli sells a round pizza with diameter 16 inches and a square pizza with side length 15 inches. Which of the two shapes gives you more pizza and by how many square inches? (Round your answer to the nearest whole number)
Answer: Square, 24 square inches
Step-by-step explanation:
Given
Diameter of round pizza [tex]d=16\ in.[/tex]
Side of square pizza [tex]a=15\ in.[/tex]
Area of circle [tex]\pi r^2[/tex]
The area of a square is [tex]a^2[/tex]
[tex]\therefore \text{Area of round Pizza}=\pi \times (\frac{16}{2})^2\\\Rightarrow A_1=\pi \times 8^2=201.088\ in.^2[/tex]
The area of square pizza is
[tex]A_2=15^2=225\ in.^2[/tex]
Clearly, the area of square pizza is more and the difference in their area is
[tex]\Rightarrow A_2-A_1=225-201.088=23.91\approx\ 24\ in.^2[/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]
