Answer:
it is 625
Step-by-step explanation:
4z ≥ 7
divide seven by four
z ≥ 1.75
or, if you need it in fraction form, it would be
z ≥ 7/4
The initial investment = $250
<span>annual simple interest rate of 3% = 0.03
</span>
Let the number of years = n
the annual increase = 0.03 * 250
At the beginning of year 1 ⇒ n = 1 ⇒⇒⇒ A(1) = 250 + 0 * 250 * 0.03 = 250
At the beginning of year 2 ⇒ n = 2 ⇒⇒⇒ A(2) = 250 + 1 * 250 * 0.03
At the beginning of year 3 ⇒ n = 3 ⇒⇒⇒ A(2) = 250 + 2 * 250 * 0.03
and so on .......
∴ <span>The formula that can be used to find the account’s balance at the beginning of year n is:
</span>
A(n) = 250 + (n-1)(0.03 • 250)
<span>At the beginning of year 14 ⇒ n = 14 ⇒ substitute with n at A(n)</span>
∴ A(14) = 250 + (14-1)(0.03*250) = 347.5
So, the correct option is <span>D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50
</span>
600 = 360 + 240
In unit circle, (x,y) = (cos(240), sin(240) ) = (-sqrt(3) / 2, -1/2)
We know that
area of the composite figure=area of the rectangle+area of semicircle
area of rectangle=b*h
b=10 ft
h=6 ft
area rectangle=10*6----> 60 ft²
area of semicircle=pi*r²/2
r=6/2----> 3 ft
area of semicircle=pi*3²/2-----> 14.13 ft²
area of the composite figure=[60+14.13]-----> 74.13 ft²-----> 74 ft²
the answer is
74 ft²
