A right triangle has side lengths a, b, and c as shown below.
Use these lengths to find sinx, tanx, and cosx.
Help plsss
Answer:
Step-by-step explanation:
The value of sinx=c/b, cosx=a/b and tanx=c/a.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given that, a right triangle has side lengths a, b, and c.
We know that, sinθ=Perpendicular/Hypotenuse, cosθ=Base/Hypotenuse and tanθ=Perpendicular/Bse
From the figure,
sinx=c/b, cosx=a/b and tanx=c/a
Therefore, the value of sinx=c/b, cosx=a/b and tanx=c/a.

Lin says that a snack machine is like a function because it outputs an item for each code input. Explain why Lin is correct.
Lin is correct.
What is a function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable, is called its function.
Given that, Lin says that a snack machine is like a function because it outputs an item for each code input.
Lin is correct because, function tells the relation between an output to its input.
A function is a relation from the set of the inputs to a set of all possible outputs, where each input is related to exactly one output.
So Lin's opinion about snack machine is correct as the snack machine is output an item for each code input.

is 9.521521521 rational or irrational
If the numbers after the decimal terminate, yes, it's rational.
9.521521521 = 9,521,521,521 / 1,000,000,000
If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.
If x = 9.521521521…, then
1000x = 9521.521521521…
Subtract x from this to eliminate the fractional part:
1000x - x = 9521.521521521… - 9.521521521…
999x = 9512
x = 9512/999
If they don't terminate, but the pattern does not continue, meaning the next few digits could be something random like
9.52152152119484929271283583457…
then the number would be irrational.

Which equation best represents the line? (4 points)
a
y = 1 over 3.x − 1
b
y = 3x − 1
c
y = −x + 1 over 3.
d
y = 3x + 1
Answer:
The equation of the line is y = 3x - 1 ⇒ b
Step-by-step explanation:
From the given graph
∵ The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
∵ (x1, y1) and (x2, y2) are two points on the line
∵ The line passes through points (0, -1) and (1, 2)
∴ x1 = 0 and y1 = -1
∴ x2 = 1 and y2 = 2
→ Substitute them in the rule of the slope to find it.
∵ m = [tex]\frac{2--1}{1-0}[/tex] = [tex]\frac{2+1}{1}[/tex] = [tex]\frac{3}{1}[/tex]
∴ m = 3
∵ The line intersects the y-axis at point (0, -1)
∴ The y-intercept = -1
∵ The form of the equation of the line is y = m x + b
∵ b is the y-intercept
∴ b = -1
→ Substitute the values of m and b in the form of the equation
∵ y = 3x + -1
∴ y = 3x - 1
∴ The equation of the line is y = 3x - 1

Answer:
c ≈ 14.9 cm
Step-by-step explanation:
I personally like to use a proportion that has the unknown in the numerator. The angle opposite c is ...
C = 180° -150° -12° = 18°
Then the law of sines tells us ...
c/sin(C) = b/sin(B)
c = sin(C)·b/sin(B) = sin(18°)/sin(12°)(10 cm)
c ≈ 14.9 cm

The sun’s mass is 1.998 * 10^30 kg. Saturn’d mass is 5.69 * 10^26 kg. How many times as great as the mass of Saturn is the mass of the sun? Show your work using scientific notation
Answer: The mass of the sun is 3.51 x 10^3 times greater.
Step-by-step explanation:
X= Mass of Sun/ Mass of Saturn
X= 1.998 x 10^30 / 5.69 x 10^26
1.998/ 5.69 = .351
10^30 / 10^26 = 10^4
You want to move the decimal a value so you would subtract 1 from 4
3.51 x 10^3
The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.
What is division?The division means the separation of something into different parts, sharing of something among different people, places, etc.
The sun’s mass is [tex]1.998 * 10^{30}[/tex] kg.
Saturn's mass is [tex]5.69 * 10^{26}[/tex] kg.
Let the mass of the Sun be X times more than the mass of the Saturn mass.
The equation that can be written as
1.998 × 10³⁰ = X × 5.69 × 10²⁶
On simplifying, the value f X will be
[tex]\rm X = \dfrac{1.998 * 10^{30}}{5.69*10^{26}}\\\\X = 3511.42 \\\\X = 3.511 * 10^3[/tex]
The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.

She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left? (b) How much money had she left?
Answer: She had left 54% of the money which is $1620.
Step-by-step explanation:
40% of $3000 = $1200
15% of $1200 = $180
$3000 - ($1200 + $180)
$3000 - $1380 = $1620
$1620 is the money she had left.
$1620 is 54% of $3000
She had 54% left of the money.

Bryan and Yuan started out at their houses and are biking towards each other. Bryan started
out first, and has already gone 5 miles. He bikes at a constant speed of 3 miles per hour.
Yuan just left, and rides at 4 miles per hour. When the boys meet halfway between their
houses, they will continue to the park together. How long will that take? How far will each
boy have ridden?
Answer:
Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.
Step-by-step explanation:
Given that Bryan and Yuan left their homes at different periods of time and at different speeds, to determine how long they will meet and how much distance they will have traveled, the following calculation must be performed:
B = 5 + (3X)
Y = 4X
B = 5 + 3x2 = 11
Y = 4x2 = 8
B = 5 + 3x3 = 14
Y = 4x3 = 12
B = 5 + 3x4 = 17
Y = 4x4 = 16
B = 5 + 3x5 = 20
Y = 4x5 = 20
Therefore, Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.

Answer:
360 for first place and 240 for second
Step-by-step explanation:
Let's say f is the first place prize, and s is the second prize.
Amaal: 4f + 2s = 1920
Brian: f + 3s = 1080
Now we can isolate and substitute.
f = 1080 - 3s
4(1080 - 3s) + 2s = 1920
4320 - 12s + 2s = 1920
10s = 4320 - 1920
10s = 2400
s = 240
f = 1080 - 3*240
= 1080 - 720
= 360

==========================================
Work Shown
45 girls : 15 boys
45/15 girls : 15/15 boys .... divide both parts by 15
3 girls : 1 boy
This tells us there are three times as many girls as there are boys.
We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.
