Answer:
The better buy is 16 cards for $12.20 because
Step-by-step explanation:
You need to find the individual price for each card in the packet. So first lets do 16 cards for $12.20, you divide $12.20 by 16 to get the price of one card. 12.2/16=0.7625, or about $0.76. Next we do $10.90 divided by 14, 10.9/14=0.7785, or about $0.78, which means 16 cards for $12.20 is the better buy!

Amy has a box that is 6 1/2 feet long, 3.25 feet wide, and 2 feet high. What is the volume of the box? V=lwh
Answer:
42.25 feet ³
Step-by-step explanation:
Volume of the box = length × width × height
Length = 6 1/2 feet = 6.5 feet
Width = 3.25 feet
Height = 2 feet
Volume of the box = length × width × height
= 6.5 feet × 3.25 feet × 2 feet
= 42.25 feet ³
Volume of the box = 42.25 cubic foot
Find all solutions to the equation. cos x = -1/2
Answer:
^^
Step-by-step explanation:
Answer:
You didn't add the range. I'll use (0<x<2π)
cosx = -1/2
x=-cos-¹(1/2)
x= -60°
Cosine is negative in the second and 3rd quadrants
180-x ---- Second quadrant
x+180 ----- 3rd quadrant
So
Our answer
180-(-60)=240° or 4π/3 second quad
180+(-60) = 120° or 2π/3---- 3rd quad

Answer:
Volume Original = 471 in³
Volume New = 343.36 in³
Step-by-step explanation:
Radius Original = 5
Radius New = (5) - 0.1(5) = 5 - 0.5 = 4.5
Height original = 6
Height new = (6) - 0.1(6) = 6 - 0.6 = 5.4
Volume original = 3.14 x 25 x 6 = 3.14 x 150 = 471
Volume New = 3.14 x 20.25 x 5.4 = 343.36

Can I please get help with this question on future value of annuities? I also am really confused on how to do the table of values.
Answer:
D
Step-by-step explanation:
I've attached one of those tables below
I'm going to solve this using the FV annuity formula
[tex]R(\frac{(1+i)^n-1}{i})[/tex]
where i is the effective rate of interest
r is the payment
n is the number of periods
to find the effective rate of interest we need to divide .08/2 (because the interest is compounding once every six months)
and the number of periods is 4*2 (because there are two periods a year(
[tex]1500(\frac{(1+.04)^8-1}{.04})=13821.33[/tex] which is equal to D
To use the table go to the effective rate of interest (4%) and then number of periods (8)
The number is 9.2142
mulitply that by the payment (1500) and get 13821.3 (D)
*the reason that the answers are slightly different is because the annuity table rounded whereas in the formula it was more exact*
9514 1404 393
Answer:
D. $13,821.30
Step-by-step explanation:
The table is given in terms of interest rate per period and number of periods. The table assumes that money is invested at the same interval that interest compounding occurs.
Since you're investing $1500 every 6 months for 4 years, the 8% annual interest rate becomes 8%·(6/12) = 4% interest each 6-month period. In 4 years, there are 8 periods of 6 months. So, you look for the multiplier shown in the table that is at the intersection of 4% interest and 8 periods.
That multiplier is 9.2142, so the future value is ...
FV = amount invested per period × multiplier from table
= $1500 × 9.2142 = $13,821.30
__
The above is how you use the table.
You can also choose the correct answer based only on your number sense, without bothering with the table.
You are paying into the annuity 8 payments of $1500 each. That is a total input of 8 × $1500 = $12,000. You will be earning interest on that money, so the future value of the annuity is more than $12,000. Only one answer choice fits that description:
D. $13,821.30

Consider the following equation.
2^(x)+3=3^(-x)
If the equation is solved using successive approximation, match the value of x to the following iterations.
9514 1404 393
Answer:
no iterations shown; the root is approximately -1.12911
Step-by-step explanation:
If your method of successive approximation is the Bisection Method, and if your initial interval is [-2, -1], then successive values of x used for reducing the interval are ...
-1.5, -1.25, -1.125, -1.1875, -1.15625
__
If your method of successive approximation is Newton's method, and if your initial guess is -1.5, then successive values of x will be ...
-1.1905079, -1.1309053, -1.1291151, -1.1291135
Another iteration confirms this last value is accurate to 8 significant figures.

A)-1
B)1
C)3

Answer:
When we have a function:
f(x)
The average rate of change in the interval a < x < b
is given by:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
Now for each of the given intervals, let's find the average rate of changes.
q(x) = (x + 3)^2
1) -6 ≤ x ≤ -4
[tex]r = \frac{(-4 + 3)^2 - (-6 + 3)^2}{-4 - (-6)} = \frac{1 - 9}{2} = -4[/tex]
here the correct option is F.
2) -3 ≤ x ≤ 0
[tex]r = \frac{(0 + 3)^2 - (-3 + 3)^2}{0 - (-3)} = \frac{9}{-3} = -3[/tex]
Here the correct option is D.
3) -6 ≤ x ≤ -3
[tex]r = \frac{(-3 + 3)^2 - (-6 + 3)^2}{-3 - (-6)} = \frac{9}{3} = 3[/tex]
Here the correct option is C
4) -3 ≤ x ≤ -2
[tex]r = \frac{(-2 + 3)^2 - (-3 + 3)^2}{-2 - (-3)} = \frac{1}{1} = 1[/tex]
Here the correct option is B.
5) -4 ≤ x ≤ -3
[tex]r = \frac{(-3 + 3)^2 - (-4 + 3)^2}{-3 - (-4)} = -1/1 = -1[/tex]
Here the correct option is A
6) -6 ≤ x ≤ 0
[tex]r = \frac{(0 + 3)^2 - (-6 + 3)^2}{0 - (-6)} = \frac{9 - 9}{6} = 0[/tex]
Here the correct option is E.

What is an exponent?Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as
y = a(b)ˣ
At x = 1, the value of y will be 4/3. Then we have
4/3 = ab ...1
At x = 2, the value of y will be 16/3. Then we have
16/3 = ab² ...2
From equation 1 and 2, we have
b = 4 and a = 1/3
Then the function will be
f(x) = 1/3 × (4)ˣ.
Then the correct option is C.

2(n-1)+ 4n= 2 (3n -1)
Answer:
Infinitely many solutions.
Step-by-step explanation:
2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.
2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)
2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.
6n - 2 = 6n - 2 Add 2n + 4n.
-6n -6n Subtract 6n from both sides.
-2 = -2
the answer is infinitely many solutions, meaning that n can be any real number.

Answer:
a) 2.188
b) John's rent is not an outlier
c) His rent has to be higher than $1,235 to be an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard University is $780 with a standard deviation of $208.
(a) John’s rent is $1,235. What is his standardized z-score?
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $1235
μ is the population mean = $780
σ is the population standard deviation = $208
Hence,
z = 1235 - 780/208
z = 2.1875
Approximately to 3 decimal place = 2.188
(b) Is John’s rent an outlier?
No it isn't
(c) How high would the rent have to be to qualify as an outlier?
John’s rent would have to be higher than $1235

10. Find the total surface area of the triangular prism
shown below.
Answer:
I think its 132.
The total surface area of the triangular prism is 200 cm².
Triangular prism surface areaSurface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)
How to find the surface area of the triangular prism?First, find the height of the prism.
Let h is the height of the prism
Use the pythagoras theorem
then
5² = (6/2)² + h²
5² = 3² + h²
25 = 9 + h²
h² = 25 - 9
h² = 16
h =4
Now apply the surface area formula
total surface area = ( 5 + 5 + 6) 11 + 6×4
= 16 × 11 + 24
= 176 +24
= 200 cm²
Hence the surface area is 200 cm²
