I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
I hope this helps.
OK. I did it. Now let's see if I can go through it without
getting too complicated.
I think the key to the whole thing is this fact:
A radius drawn perpendicular to a chord bisects the chord.
That tells us several things:
-- OM bisects AB.
'M' is the midpoint of AB.
AM is half of AB.
-- ON bisects AC.
'N' is the midpoint of AC.
AN is half of AC.
-- Since AC is half of AB,
AN is half of AM.
a = b/2
Now look at the right triangle inside the rectangle.
'r' is the hypotenuse, so
a² + b² = r²
But a = b/2, so (b/2)² + b² = r²
(b/2)² = b²/4 b²/4 + b² = r²
Multiply each side by 4: b² + 4b² = 4r²
- - - - - - - - - - -
0 + 5b² = 4r²
Repeat the
original equation: a² + b² = r²
Subtract the last
two equations: -a² + 4b² = 3r²
Add a² to each side: 4b² = a² + 3r² . <=== ! ! !
That would make rover 124.05 pounds because it sayes he is 48.8 pounds more than the other dogs that means to add that weight to the 75.25 pd to get his actual weight.
Answer:
The cost is called DOWN PAYMENT. The down payment is an initial payment you have to make when buying something on credt.
The down payment varies depending on the price of what you're buying and not all credits require a down payment. As an example, I'm attaching an example of a phone you can buy on credit and no downpayment is required.
The down payment is expressed in percentage of the total cost of the item/property you're buying. In Gerald's case, the down payment was 10% of the total value of the house.
