What is s??
A 44°
B 35.3°
C. 37.9°
D. 22°
Answer: Choice B) 35.3 degrees
======================================================
Work Shown:
Apply the law of sines
sin(S)/s = sin(R)/r
sin(S)/16 = sin(120)/24
sin(S) = 16*sin(120)/24
sin(S) = 0.57735026918962
S = arcsin(0.57735026918962)
S = 35.2643896827542
S = 35.3

Mr. Hartman, the school librarian, is ordering new keyboards and mice for all of the school's computer labs. Each keyboard costs $13.50, and each mouse costs $6.50. There are 3 computer labs in the school, and each computer lab has s computer stations. Pick all the expressions that represent how much Mr. Hartman will spend on new keyboards and mice.
Answer:
3 * 20s
Step-by-step explanation:
In order to find out how much Mr. Hartman will spend in total we first need to multiply the price of the keyboard and mouse by the number of computers in a single computer station. Once we have these products we add them together. Finally, we multiply this new value by 3 since there are a total of 3 computer stations. If we turn this into an expression it would be the following...
3 * (13.50s + 6.50s)
We can even simplify this by first adding the cost of the keyboard and mouse and then multiplying by s
3 * 20s
I want you to do a linear and exponential model for Yakima's Population. Use the DATA below: in 1990 => P0 = 64792 in 2010 => P20 = 91646 A) Find the linear model of population growth. B) Predict the population for 2050. C) Find the exponential model of population growth. D) Predict the population for 2050. E) Which one seems more realistic?
Answer:
(a) [tex]P(x) = 1342.7x + 64792[/tex]
(b) [tex]P(60) = 145354[/tex]
(c) [tex]P(x) = 64792 *1.0175^x[/tex]
(d) [tex]P(60) = 183491[/tex]
(e) The exponential model is more realistic
Step-by-step explanation:
Given
[tex]1990 ==> P_0 =64792[/tex]
[tex]2010 ==> P_{20} =91646[/tex]
Solving (a): The linear model of the population growth
First, we calculate the slope of the function.
[tex]m = \frac{P_{20} - P_0}{20 - 0}[/tex]
[tex]m = \frac{91646 - 64792}{20 - 0}[/tex]
[tex]m = \frac{26854}{20}[/tex]
[tex]m = 1342.7[/tex]
The linear equation is then calculated using:
[tex]P(x) - P_0 = m(x - x_0)[/tex]
[tex]P(x) - 64792 = 1342.7(x - 0)[/tex]
[tex]P(x) - 64792 = 1342.7(x)[/tex]
[tex]P(x) - 64792 = 1342.7x[/tex]
Make P(x) the subject
[tex]P(x) = 1342.7x + 64792[/tex]
Solving (b): The population in 2050
First, calculate x:
[tex]x = 2050 - 1990[/tex]
[tex]x = 60[/tex]
Substitute 60 for x in [tex]P(x) = 1342.7x + 64792[/tex]
[tex]P(60) = 1342.7 * 60 + 64792[/tex]
[tex]P(60) = 80562 + 64792[/tex]
[tex]P(60) = 145354[/tex]
The population in 2050 is 145354
Solving (c): The exponential model of the population growth
An exponential model is:
[tex]y = ab^x[/tex]
In this case, it is:
[tex]P(x) = P_0 * b^x[/tex]
For x = 20, we have:
[tex]P(20) = P_0 * b^{20[/tex]
Substitute values for P(20) and P0
[tex]91646 = 64792 * b^{20[/tex]
Divide both sides by 64792
[tex]\frac{91646 }{64792} = \frac{64792 * b^{20}}{64792}[/tex]
[tex]\frac{91646 }{64792} = b^{20}[/tex]
[tex]1.41446474873 = b^{20}[/tex]
Take the 20th root of both sides
[tex]\sqrt[20]{1.41446474873} = b[/tex]
[tex]b = \sqrt[20]{1.41446474873}[/tex]
[tex]b = 1.0175[/tex]
So, the model is:
[tex]P(x) = P_0 * b^x[/tex]
[tex]P(x) = 64792 *1.0175^x[/tex]
Solving (d): The population in 2050
First, calculate x:
[tex]x = 2050 - 1990[/tex]
[tex]x = 60[/tex]
Substitute 60 for x in [tex]P(x) = 64792 *1.0175^x[/tex]
[tex]P(60) = 64792 *1.0175^{60[/tex]
[tex]P(60) = 64792 *2.832[/tex]
[tex]P(60) = 183490.944[/tex]
[tex]P(60) = 183491[/tex] ---- approximated
(e) The most realistic model
The exponential model is more realistic. This is so because:
The linear model grows at a constant linear rate which means that, every year a certain amount of individuals is added to the society. However, this is not always so because it is almost impossible to for growth rate to be constant
A curve in the exponential model shows that the addition of individuals in the society every year is not always constant.

Rearrange p=r+3 to make r the subject
Answer:
r = p-3 this is correct answer of this question
The equation p=r+3 can be rearranged as r=p-3
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is p=r+3
p equal to r plus r
Plus is the operator of addition and p and r are variables
Subtracting 3 from both sides, we get:
p - 3 = r + 3 - 3
Simplifying the right-hand side:
p - 3 = r
Therefore, r = p - 3.
Hence, the equation p=r+3 can be rearranged as r=p-3

Ellen Greenberg loves to make and fly kites. Ellen is planning to open a shop that
sells custom-made kites. She asks for your advice to help her set financial goals.
Ellen estimates that after expenses, she can make a $15 profit on each kite she
sells. If her annual income goal is $15,400, how many kites will she have to sell?
Answer:
She must sell 1026.66666667 kites
Step-by-step explanation:
15,400/15
The number of kites that Ellen needs to sell to complete her annual goal is 1027.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Ellen can make a $15 profit on each kite she sells. Also, Ellen's annual income goal is to have $15,400. Therefore, the number of kites that Ellen needs to sell is,
Number of kites that Ellen will sell = Annual income goal/Profit on each kite
Number of kites that Ellen will sell = $15,400 / $15
= 1026.6667
Since Ellen can not sell half kites, therefore, she needs to sell 1027 kites to complete her annual income goal.
Hence, the number of kites that Ellen needs to sell to complete her annual goal is 1027.

Dora buys some T-shirts for $8.75 each and pairs of shoes for $27.50 each. If she buys 4 T-shirts, how much money would she have to spend in all
8.75*4=35 so $35 for shirts
and depending on how many shoes she buys but lets just say one pair
35+27.50= 62.50 so it would be a total of $62.50

P = 100 - 20 cos (8πt/3) That's (8 pi t /3) where t is the time (in seconds). What is the period of the model? Discuss what the period represents in the context of this model.
Answer:
The period of the model is [tex]\frac{3\pi}{4}[/tex] seconds. The period represents the time needed for the function to complete one cycle.
Step-by-step explanation:
Cosine is a trigonometric function and trigonometric functions are characterized by having a periodical behavior. The period is the time needed for the function to cover an angle of [tex]2\pi[/tex] radians. By this approach we find that:
[tex]\frac{8\pi\cdot t}{3} = \frac{2\pi\cdot t}{T}[/tex] (1)
Where:
[tex]t[/tex] - Time, measured in seconds.
[tex]T[/tex] - Period, measured in seconds.
Then, we solve (1) for [tex]T[/tex]:
[tex]\frac{8}{3} = \frac{2\pi}{T}[/tex]
[tex]T = \frac{6\pi}{8}\,s[/tex]
[tex]T = \frac{3\pi}{4}\,s[/tex]
The period of the model is [tex]\frac{3\pi}{4}[/tex] seconds. The period represents the time needed for the function to complete one cycle.

Find the slope of the line y= -8/5x + 2
Step-by-step explanation:
Given
y = - 8 /5 x + 2
Comparing the given equation with y = mx + c
slope (m) = - 8/5
Hope it will help :)
Answer:
-8/5
Explanation:
The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.
In slope intercept, the slope is always the number that comes before x.
In the equation y = -8/5x + 2, that number is -8/5.
Hence, the answer is -8/5.
