Answer 1

The calculation of the trigonometry illustrates that:

sin 45° = 1/✓2

cos45/tan 45 =

cos 45 sin 45 = 1/2

How to illustrate the trigonometry?

Opposite = 1

Adjacent = 1

Hypothenuse = ✓2

Tan 45 = opposite/adjacent = 1

Sin 45 = opposite/hypothenuse = 1/✓2

Cos 45 = adjacent/hypothenuse = 1/✓2

cos45/tan 45 = (1/✓2) / 1 = 1/✓2

Cos 45 sin 45 = 1/✓2 × 1/✓2 = 1/2

Tyler is observing the ascent of a
steel beam being lifted by a crane
from a position about 250 feet
away. What function models the
height h in feet of the beam as a
function of the angle of inclination
from Tyler's position to the steel
beam?

Answers

Answer:

Step-by-step explanation:

tanθ = h/250

h = 250tanθ

The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ feet

What is angle of inclination?

"The angle inclination of a line is the angle formed by the intersection of the line and the x-axis."

What are trigonometric functions?

"The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths."

We have

Adjacent side = 250 feet

From the figure,

We can write trigonometric function

Tanθ = [tex]\frac{AB}{BC}[/tex]

Tanθ = [tex]\frac{h}{250}[/tex]

⇒ h = 250 tanθ feet

Hence, The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ

Find the general solution of (x+3)y’=2y

Answers

Answer:

[tex]y=C(x+3)^2[/tex]

Step-by-step explanation:

We are given:

[tex]\displaystyle (x+3)y^\prime=2y[/tex]

Separation of Variables:

[tex]\displaystyle \frac{1}{y}\frac{dy}{dx}=\frac{2}{x+3}[/tex]

So:

[tex]\displaystyle \frac{dy}{y}=\frac{2}{x+3} \, dx[/tex]

Integrate:

[tex]\displaystyle \int\frac{dy}{y}=\int\frac{2}{x+3}\, dx[/tex]

Integrate:

[tex]\displaystyle \ln|y|=2\ln|x+3|+C[/tex]

Raise both sides to e:

[tex]|y|=e^{2\ln|x+3|+C}[/tex]

Simplify:

[tex]|y|=(e^{\ln|x+3|})^2\cdot e^C[/tex]

So:

[tex]|y|=C|x+3|^2[/tex]

Simplify:

[tex]y=\pm C(x+3)^2=C(x+3)^2[/tex]

A function, f(x), passes through the point (0,2). Another function is represented by the equation g(x)=x^2−2x−3. What is the y-intercept of g(x) and which function has the greater y-intercept

Answers

Answer:

The y-intercept of function f(x) is 2.The y-intercept of function g(x) is -3.

Therefore, we conclude that function f(x) has a greater y-intercept.

Step-by-step explanation:

The y-intercept of any function can be determined by checking the value of y at x = 0.

Important Tip

A point where the graph meets the y-axis — y-intercept.

Determining the y-intercept of the function f(x)

Given the function f(x) passes through the point (0,2).

It means at x = 0, the value of y = 2

Thus, the y-intercept of function f(x) is 2.

Determining the y-intercept of the function g(x)

Given the function g(x)

[tex]g\left(x\right)=x^2-2x-3[/tex]

substitute x = 0 in the function equation

[tex]g\left(0\right)=\left(0\right)^2-2\left(0\right)-3[/tex]

[tex]g\left(0\right)=0-0-3[/tex]

[tex]g\left(0\right)=-3[/tex]

It means at x = 0, the value of y = -3

Thus, the y-intercept of function g(x) is -3.

Conclusion:

The y-intercept of function f(x) is 2.The y-intercept of function g(x) is -3.

As 2 > -3

Therefore, we conclude that function f(x) has a greater y-intercept.

find c and round to the nearest tenth

Answers

Answer:

Step-by-step explanation:

<C = ?

a = 22

b = 20

c = 18

Formula

c^2 = a^2 + b^2 - 2*a*b* cos(C)

Solution

18^2 = 22^2 + 20^2 - 2*22*20*cos(C)

324 = 484 + 400 - 880*cos(C)

324 = 884 - 880*Cos(C)

-560 = - 880 * cos(C)

-560 / - 880 = cos(C)

0.63636 = cos(C)

C = cos-1(0.63636)

C =50.48

Megan’s TV had a base price of $189 and the sales tax was 6.88%. Over the next four years, the TV consumed an average of $0.06 of electricity every day. It also needed repairs twice, costing $29 each time. After four years, Megan got a new TV. What was the lifetime cost of Megan’s TV? (Remember that one in every four years is a leap year.)

a.
$357.68
b.
$318.66
c.
$347.66
d.
$351.65

Answers

Answer:

Step-by-step explanation:

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00

4 years = 3×365 days + 366 days = 1461 days

cost of electricity = 1461 days × $0.06/day = $87.66

lifetime cost = purchase price + electricity + repairs

= $202.00 + $87.66 + 2·$29

= $347.66

347.66 is your answer
