If tan x = m, what is sin x in terms of m?​

Answers

Answer: m/sqrt(m^2)+1

Step-by-step explanation: if tan x = m, then the opposite angle is m and the adjacent angle is 1 so 1 squared plus m squared equals c squared. c = sqrt (1 + m^2)

sin x = opposite/hypotenuse = m/sqrt(m^2)+1

The value of sin x in terms of m is [tex]\frac{m}{\sqrt {m^2+1}}[/tex]

Trigonometry are identities used to express the sides and angles of a triangle.

According to SOH CAH TOA,

Tan θ = Opposite/Adjacent

Given that tan x = m

Opposite  = m

Adjacent = 1

Get the hypotenuse using the pythagoras theorem

Hyp² = Opp² + Adj²

Hyp² = m²+1²

Hyp² = m²+1

Take the square root of both sides

√Hyp² =√m²+1

Hypotenuse = √m²+1

Next is to get sin x:

Sin x = Opposite/Hypotenuse

Sin x = [tex]\frac{m}{\sqrt {m^2+1}}[/tex]

Hence the value of sin x in terms of m is

[tex]\frac{m}{\sqrt {m^2+1}}[/tex]

In triangle ABC, we can draw a perpendicular line segment from vertex C to segment AB. The intersection of AB and the perpendicular is called E. We know that BE is the shortest distance from B to and that is the shortest distance from A to CE because of the shortest distance theorem. Therefore, BC > BE and AC > AE. Next, add the inequalities: BC + AC > BE + AE. Then, BE + AE = BA because of the . Therefore, BC + AC > BA by substitution.

Find the simple interest earned, to the nearest cent, for the principal, interest rate, and time.



$530, 6%, 1 year

Answers

The simple interest earned on $530 at 5.5% rate for 1 years is $31.80.

How to calculate simple interest?

The formula for simple interest is expressed mathematically as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time period.

Given the data in the question;

Principal P = $530Interest rate r = 6%Time period t = 1 yearInterest I = ?

First, convert the rate from percent to a decimal form

Rate r = 6%

Rate r = 6/100

Rate r = 0.06

To determine the simple interest earned, plug the given values into the simple interest formula and solve for I.

I = P × r × t

I = $530 × 0.06 × 1

I = $530 × 0.06

I = $31.80

Therefore, the simple interest accumulated after 1 years is $31.80.

We have to simplify the expression,

⇒ 5 1/6 - 7 1/3

Firstly we can change it into improper fraction,

⇒ 5 1/6 - 7 1/3

⇒ 31/6 - 22/3

Make denominator same by taking LCM of 6 and 3 which is 6,

⇒ 31/6 - 44/6

⇒ (31 - 44) / 6

[tex]slope = \frac{ - 6}{ - 25} \\ [/tex]

[tex]slope = \frac{6}{25} \\ [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Answer:

The slope is [tex]\frac{6}{25}[/tex] or [tex]0.24[/tex].

Step-by-step explanation:

This is the formula to calculate the slope from two given points: [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] . Now, substitute (x1, y1) and (x2, y2) for (15,9) and (-10,3). [tex]slope=\frac{3-9}{-10-15}[/tex] . That equation becomes [tex]slope=\frac{-6}{-25}[/tex] . You have to change [tex]\frac{-6}{-25}[/tex] to [tex]\frac{6}{25}[/tex] . The slope is 6/25 or in decimal form, 0.24.

Which exponential function is represented by the graph?

O f(x) = 1/2(2)x
O f(x) = 1/2(1/2)x
Of(x) = 2(2)x
PLEASE HELP MEE!

Answers

Answer:

f(x) = [tex]\frac{1}{2}[/tex] [tex](2)^{x}[/tex]

Step-by-step explanation:

Using the standard form of the exponential function

y = a [tex]b^{x}[/tex]

To find a and b , substitute ordered pairs from the graph

Using (0, 0.5 ), then

0.5 = a[tex]b^{0}[/tex] [

a = 0.5 , so

y = [tex]\frac{1}{2}[/tex] [tex]b^{x}[/tex]

Using (1, 1) , then

1 = [tex]\frac{1}{2}[/tex][tex]b^{1}[/tex] , thus

b = 2

f(x) = [tex]\frac{1}{2}[/tex][tex](2)^{x}[/tex] ← exponential function representing graph

In 2004, a bonding bill for $4 million was passed by the House, but it was later thrown out in a conference committee. In addition, a number of the PRT supporters have faced some legal issues and have had to step off to the sidelines, thereby making the PRT just another idea simmering on the back burner. For example, Professor J. Edward Anderson, a key developer of the Skyweb PRT and co-founder of the Taxi 2000 Corporation, was denied in his attempt to regain control of the company, and in 2005, had a lawsuit filed against him. Minneapolis Councilmember Gary Dean Zimmerman, another supporter of the PRT system, was charged by the Attorney General with forcing bribes from the developer. Yet another supporter, Rep.
