sin^-1(sin 17°)
Answer:
uhm 0 degrees
Step-by-step explanation:
The value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.
What is inverse trigonometry?Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The inverse trigonometric expression is given below.
⇒ sin⁻¹(sin 17°)
We know that the value of sin⁻¹(sin θ) is θ.
Then the value of the inverse trigonometric expression will be
⇒ sin⁻¹(sin 17°)
⇒ 17°
Thus, the value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.

Ariana wants to buy a house in a few years. She spends $100 a month on takeout coffee. She spends $200 a month on fast food. What can she do to save money for her house?
Answer:
Hm, if Ariana wants to save money for her house, she should spend less money on fast food a month because if she spending $100 dollars for takeout coffee and spending at the same time a month for fast food. she should eat less fast food and less money for coffee because she would be spending way too much money because F = $200 and C = $100 dollars, so $200 + $100 dollars would be $300 dollars a month. she could still have takeout coffee however, not every month. The fast food needs to be taken out of her diet as well because its the fact its unhealthy and costing her way too much money, she should stop having fast food and not have coffee or the fast food EVERY MONTH, she could have the fast food evert 5 months and her takeout coffee every once a month. hopefully this helps ^^

Kirk made the graph to show his prediction of a population of bacteria over time. Which function best models the data in the graph?
mc001-1. jpg
mc001-3. jpg
mc001-2. jpg
mc001-4. jpg
Jana predicts that the population, y, will grow according to y = 12 log(x + 1) + 10, where x is the time in minutes. How much greater does Kirk’s model predict the population will be after 60 minutes than Jana’s model?
✔ greater by about 50 bacteria
Answer:
greater by about 50 bacteria
hope this helps,
T
Step-by-step explanation:
Populations can be modeled by exponential functions and logarithm functions.
Kirk's function is: [tex]\mathbf{f(x) = (10)2^{\frac{x}{20}}}[/tex]Kirk’s model predict the population will be greater than about 50 bacteria after 60 minutes than Jana’s modelKirk's graph is an exponential function, and it is represented as:
[tex]\mathbf{y = ab^x}[/tex]
From the graph (see attachment);
x = 0, when y =10.
So, we have:
[tex]\mathbf{10 = ab^0}[/tex]
[tex]\mathbf{10 = a\times 1}[/tex]
[tex]\mathbf{10 = a}[/tex]
Rewrite as:
[tex]\mathbf{a = 10 }[/tex]
Substitute [tex]\mathbf{a = 10 }[/tex] in [tex]\mathbf{y = ab^x}[/tex]
So, we have:
[tex]\mathbf{y = 10(b)^x}[/tex]
x = 20, when y =20.
[tex]\mathbf{20 = 10(b)^{20}}[/tex]
Divide both sides by 10
[tex]\mathbf{2 = b^{20}}[/tex]
Take 20th root of both sides
[tex]\mathbf{b = 2^{\frac{1}{20}}}[/tex]
Substitute [tex]\mathbf{b = 2^{\frac{1}{20}}}[/tex] in [tex]\mathbf{y = 10(b)^x}[/tex]
[tex]\mathbf{y = 10(2^{\frac{1}{20}})^x}[/tex]
[tex]\mathbf{y = (10)2^{\frac{x}{20}}}[/tex]
Represent as function
[tex]\mathbf{f(x) = (10)2^{\frac{x}{20}}}[/tex]
So, Kirk's function is: [tex]\mathbf{f(x) = (10)2^{\frac{x}{20}}}[/tex]
When x = 60, we have:
[tex]\mathbf{f(60) = (10)2^{\frac{60}{20}}}[/tex]
[tex]\mathbf{f(60) = (10)2^3}[/tex]
[tex]\mathbf{f(60) = (10)8}[/tex]
[tex]\mathbf{f(60) = 80}[/tex] ---- Kirk's model
For Jana's model, we have:
[tex]\mathbf{y = 12log(x + 1) + 10}[/tex]
Substitute 60 for x
[tex]\mathbf{y = 12log(60 + 1) + 10}[/tex]
[tex]\mathbf{y = 12log(61) + 10}[/tex]
Using a calculator, we have:
[tex]\mathbf{y \approx 31}[/tex] --- Jana's model
Calculate the difference between both models
[tex]\mathbf{d = 80 - 31}[/tex]
[tex]\mathbf{d = 49}[/tex]
Approximate
[tex]\mathbf{d \approx 50}[/tex]
Hence, Kirk’s model predict the population will be greater than about 50 bacteria after 60 minutes than Jana’s model

Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y=-1/3 +4.
Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
y=3x-9

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Arun sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 128 visitors purchased no costume. 3 visitors purchased exactly one costume. 5 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase exactly one costume as a fraction in simplest form.
Answer:
3/136
Step-by-step explanation:
128 + 3 + 5 = 136
= 3/136 (simplest form)

Answer:
y = (x-4)²
Step-by-step explanation:
vertex (h , k)
h = 4 .... axis of symmetry
k = (6 + -6) / 2 = 0 .... midpoint of focus and directrix
equation of parabola: y = (x-4)² y = (x-h)² + k
the coordinates of point D are (-10, -3) and the coordinates for point G are (-2, -3). Where is point D in relation to point G?
Answer: Choice C
Point D is 8 units to the left of point G
=================================================
Explanation:
Refer to the diagram below. I've graphed both points on the same xy grid. We can draw a horizontal line through points D and G to form a number line of sorts. Count the number of spaces along this number line to go from G to D. You should count 8 spaces to the left.
Effectively, this is the same as drawing a number line and plotting -10 and -2 on this number line. We only worry about the x coordinates of the two points since the y coordinates are the same (both are y = -3). Note how -10 is eight units to the left of -2 on the number line.

Answer for first question:
tangent of P= 4/3
cosine of P= 3/5
sine of P= 4/5
Explanation:
tangent = opposite/ adjacent
cosine = adjacent/ hypotenuse
sine = opposite/ hypotenuse
2nd question: x=12
Explanation: When you have a 45-45-90 degree angle the hypotenuse will always be twice the base of the triangle and the longer leg will always be √2 times the base. Here you have the measurement of one of the longer sides- 6√2. Because we have this measurement, we know the base is going to be 6 and the hypotenuse, x, will be 12.
3rd question: cos y
Explanation: Let's give the triangle some measurements to make this easier.
The hypotenuse= 5.
The adjacent side of x= 3.
The opposite side of x= 4.
sine= opposite/ hypotenuse = sin x = 4/5
cosine= adjacent/ hypotenuse = cos x = 3/5
As you see, 3/5 and 4/5 are not equal, but when you try cos y and sin x. You will find that they are equal.

-22.8 = 6n check your solution
Answer:
-3.8=n
Step-by-step explanation:
My goal is to get n all by itself, but its multiplied by 6. If I do the inverse operation (which is division) on both sides I will get -22.8/6=n. Now I can just simply combine the like terms and finalize my answer. 6 * 3=18 but -22.8 is a decimal number so my answer will range from around 3.5-3.9. if I divide -22.8/6 I get -3.8. My final answer is n=-3.8
