Answer:
<em>171200 pennies</em>
Step-by-step explanation:
Amount after 2 years = Principal + Interest
Given
Principal = £1600
Rate = 3.5%
Time = 2years
Get the interest
Interest = PRT/100
Interest = 1600*3.5*2/100
Interest = 32 * 3.5
Interest = £112
Get the amount after 2 years;
Recall that:
Amount after 2 years = Principal + Interest
Amount after 2 years = 1600 + 112
Amount after 2 years = £1712
<em>Hence the amount Dan will have after 2 years is £1712</em>
<em>1712 pounds = (1712 * 100)penny</em>
<em>1712 pounds = 171200 pennies</em>
<span>(n-2)180=sum of the interior angles.
Where n=number of angles of a regular polygon.
(n-2)180=2340
divide both sides by 180 and get
n-2=13
add 2 to both sides and get
n=15 Therefore, this polygon has 15 sides.</span>
B) 28.26 squared feet.
To fine area, you need the radius. radius is half of diameter. half of 6 is 3. A=πr2=π·32≈28.27433
Im not sure on the syntax here, but i assume the question is (4/9)^-1
(4/9)^-1
= (4^-1)/(9^-1)
A negative power is an inverse of the positive power
i.e. x^-2 = 1/x^2
This is because if we have say x^3/x^5 we simplify it by cancelling x^3 which gives 1/x^2.
Another way to think of it is to subtract the power of the bottom x from the power of the top x: 3-5 = -2 so x^3/x^5 = x^-2.
I hope this explains how negitive powers are the inverse of the positive power.
So....
(4^-1)/(9^-1)
= 9/4
Because the inverse of 4 is 1/4 and the inverse of 1/9 is 9
