just olya [345]

Answer:

241904.9483

≈ 241905

Step-by-step explanation:

Given that,

current amount of house = 180,000

value of the home increases at a rate of 3% per year

To find,

approximate value of the home after 10 years using exponential function

<h2>Equation</h2><h2>a(1 + r)^t</h2>

where a is the amount of house = 180,000

r is the interest rate per annum = 3% = 3/100 = 0.03

t is the number of years = 10

180,000 (1+0.03)^10

180,000 (1.03)^10

241904.9483

≈ 241905

Oksana_A [137]
I =  / r            where I = current and r = resistance

80 = k / 50 so
k = 400

so we have I = 400/r

when r = 40  
I = 400/40 = 10 amps

Proof that :<br><img src="https://tex.z-dn.net/?f=%20%7Bsin%7D%5E%7B2%7D%20%5Ctheta%20%2B%20%20%7Bcos%7D%5E%7B2%7D%20%5C%3A%5Cth
Arisa [49]

Answer:

Solution given:

Right angled triangle ABC is drawn where <C=\theta

we know that

\displaystyle Sin\theta=\frac{opposite}{hypotenuse} =\frac{AB}{AC}

\displaystyle Cos\theta=\frac{adjacent}{hypotenuse}=\frac{BC}{AC}

Now

left hand side

\displaystyle {sin}^{2} \theta + {cos}^{2} \:\theta

Substituting value

(\frac{AB}{AC})²+(\frac{BC}{AC})²

distributing power

\frac{AB²}{AC²}+\frac{BC²}{AC²}

Taking L.C.M

\displaystyle \frac{AB²+BC²}{AC²}....[I]

In ∆ABC By using Pythagoras law we get

\boxed{\green{\bold{Opposite²+adjacent²=hypotenuse²}}}

AB²+BC²=AC²

Substituting value of AB²+BC² in equation [I]

we get

\displaystyle \frac{AC²}{AC²}

=1

Right hand side
