Answer:
221.87 feet
Step-by-step explanation:
Given that,
A 525 ft cable runs from the top of an antenna to the ground.
The angle of elevation made by the ground to the top of an antena 25°
We need to find the height of the antenna.
Using trigonometry,
Hypotenuse, H = 525 ft
θ = 25°
So,

So, the height of the antenna is equal to 221.87 feet.
Answer:
y = -16
Step-by-step explanation:
f(x)=3/4x+12 (replace f(x) with y)
y =3/4x+12 (rearrange to express x in terms of y)
y - 12=3/4 x
3/4 x = y - 12
3x = 4(y - 12)
x = (4/3)(y - 12)
x = (4/3)y - (4/3)(12)
x = (4/3)y - 16
(y) = (4/3)y - 16
(x) = (4/3)x - 16
comparing to general form
y = mx + b where b is the y-intercept
b = -16
Hence the y-intercept is y = -16
The total balance of the amount of money deposited into the account at the end of 4 years is $3194.76.
<h3>What is the total balance?</h3>
Simple interest rate is the interest that is paid only on the principal portion of the amount deposited. Compound interest is when interest is earned on the amount deposited and the interest accrued.
Compound value = amount deposited x (1 + interest rate) ^number of years
800(1.0125)^4 = $840.76
Future value of the account with simple interest = amount deposited + (principal x time x interest rate)
2200 + (2200 x 0.0175 x4) = $2354
Total value = 2354 + 840.76 = $3194.76
