Lelechka [254]
2w + 2L = 100
2w = L - 8

L - 8 + 2L = 100
3L = 108
L = 36

2w = L - 8
2w = 36 - 8

Find the side indicated by the variable. Round to the nearest tenth.​
zepelin [54]

Answer:

b ≈ 25.6

Step-by-step explanation:

From the figure attached,

By applying tangent rule in the given triangle,

tan(32°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(32°) = \frac{16}{b}

b = \frac{16}{\text{tan}(32)}

b = \frac{16}{0.62487}

b = 25.605

b ≈ 25.6

The function f(x) = 3,005(1 + 0.03)x represents the amount of money in a savings account where x represents time in years. What
Damm [24]

Answer:

Principal or Initial Amount of Money

Step-by-step explanation:

Given, f(x) = 3005(1+0.03)^x.  

Now, comparing with f(x)= ab^x where  

a = initial value

b = rate of growth

x = time or period  

This, function is an exponential growth function. So by comparing we get a= 3005 which is the initial value b = 0.03.  

But in this case according to the question, the function f(x)= 3005(1+0.03)^x represents the amount of money in a savings. So the answer is 3005 which is the initial money.
