12. If you buy a bag of pretzels ($0.75 per bag) and a Pepsi ($1.25) every weekday at work from a vending machine, how much do you spend on the vending machine products over the course of a year (52 weeks)
0.75 + 1.25 = $2 everyday
Since there are 5 weekdays:
5 x 2 = $10 a week
Since there are 52 weeks in a year:
10 x 52 = $520 a year!
classify the pair of angles. then find the value of x.
(need help with 13 & 15!)
The value of x from the figures are 18 and 26 respectively
Vertical and complementary angles13) From the diagram, the angles at the corner is 90 degrees. This shows that the sum of the angles is complementary (sum is 90 degrees)
3x + 2x = 90
5x = 90
x = 90/5
x = 18
15) Since the sum of angles on a straight line is supplementary, hence;
6x + x - 2 = 180
7x = 182
x = 182/7
x = 26
Hence the value of x from the figures are 18 and 26 respectively

to the nearest whole number, what is the sum of the first 25 terms?
The explicit formula is [tex]a_{n-1} = 256 * 0.5^{n-1[/tex] and the sum of the first 25 terms is approximately 512
The explicit formulaThe given parameters are:
[tex]a_0 = 256[/tex]
[tex]a_{n +1} = 0.5a_n[/tex]
Set n = 0
[tex]a_1 = 0.5a_0[/tex]
Substitute 256 for a0
[tex]a_1 = 0.5 * 256[/tex]
[tex]a_1 = 128[/tex]
This means that the common ratio is 0.5.
The explicit formula is then represented as:
[tex]a_{n-1} = a_0 * r^{n-1[/tex]
This gives
[tex]a_{n-1} = 256 * 0.5^{n-1[/tex]
The sum of the first 25 termsThis is calculated using:
[tex]S_n = \frac{a_0(r^{n-1} -1)}{r - 1}[/tex]
This gives
[tex]S_{25} = \frac{256 * (0.5^{25-1} -1)}{0.5 - 1}[/tex]

At the equilibrium price p, we can solve for the quantity of goods x :
demand = supply
5200 - 0.0005x = 2800 + 0.0003x
2400 = 0.0008x
x = 3,000,000
With this quantity of goods, the equilibrium price is
p = 5200 - 0.0005 (3,000,000)
p = 5200 - 1500

The value of x and y in the right angle triangle are 6 units and 10.4 units.
How to find side of a right triangle?The sides of a right triangle can be found as follows:
using trigonometric ratio,
sin 60 = opposite / hypotenuse
sin 60 = y / 12
cross multiply
y = 12 sin 60
y = 10.3923048454
y = 10.4 units
Therefore,
cos 60 = adjacent / hypotenuse
cos 60 = x / 12
x = 12 cos 60
x = 6 units

Here we have a right triangle.
x is the adjacent cathetus to the shown angle, and y is the opposite cathetus. We can see that the hypotenuse measures 12.
Then using trigonometric relations we get:
y = sin(60°)*12 = 10.39x = cos(60°)*12 = 6So we conclude that x measures 6 units and y measures 10.39 units.

WHAT IS THE CONSTANT AND WHY
Answer:
6
Step-by-step explanation:
The constant is the number that's all by itself with no variable.
x is the variable. It can vary (change) as you use different values for x.
There are four terms here in the expression in your question they are separated by the plus or minus signs.
2 and 4 are exponents. 3 and 5 are coefficients.
x^4 is a fourth degree term. 3x^2 is a second degree term. 5x is a first degree term. The whole expression is 4th degree because the highest exponent is 4.
But the 6 is all by itself. 6 is the constant.

The option (A) "The graph of function f is shifted right 3 units and up 4 units. " is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a transformation function:
g(x) = f(x - 3) + 4
The parent function is f(x).
First transformation:
x → (x - 3)
The function will shift right by 3 units.
Second transformation:
Add 4 to the function:

The graph of f(x) = 3.2x-3 is shown below. g(x) is a transformation of f(x).
How would you write the equation for the function g(x)?
Answer:
C. g(x) = 3·2^x +2
Step-by-step explanation:
The graph of g(x) appears to be a translation upward of the graph of f(x).
__
To find the equation of g(x), we can add 5 to f(x), since the translation appears to be 5 units. (The y-intercept of f(x) is 0; the y-intercept of g(x) is 5.)
g(x) = f(x) +5
g(x) = (3·2^x -3) +5
g(x) = 3·2^x +2
__
You can also determine the correct choice by looking at the value at x=0:
A. g(0) = 3 +6 = 9
B. g(0) = 1 +3 = 4
C. g(0) = 3 +2 = 5 . . . . matches g(0) on the given graph
D. g(0) = 3

The cash value of the computer system in 3 years will be $1632. The correct option is the third option $1632
DepreciationFrom the question, we are to determine the cash value of the computer system in 3 years
From the given information,
The computer system cost $2,395 and it will depreciate at a rate of 12% a year
After the first year, the worth of the computer system will be
$2,395 - (12% of $2,395)
$2,395 - (0.12 × $2,395)
= $2,395 - $287.4
= $2107.6
After the second year, the worth of the computer system will be
$2107.6 - (12% of $2107.6)
$2107.6 - (0.12 × $2107.6)
= $2107.6 - $252.912
= $1854.688
After the third year, the worth of the computer system will be
$1854.688 - (12% of $1854.688)
$1854.688 - (0.12 × $1854.688)
= $1854.688 - $222.56256
= $1632.12544
≅ $1632
Hence, the cash value of the computer system in 3 years will be $1632. The correct option is the third option $1632
