Eddie the elf made 13 toys one day in the workshop. some were dolls and the rest were action figures. the number of action figur
Lunna [17]
To solve this problem we first call x = number of action figures, y = number of dolles. A system of two equations with two unknowns must be made to describe the problem. The system is the following:
 (x + 1) + y = 13
 1/2 * x = y.
 Then solving the system we have that x = 8 and y = 4.
 Since we know that the number of action figures is twice as many dolls plus one, then x = 8 + 1 = 9.
 Thus,
 dollos = 4
 action figures = 9

A savings account compounds interest, at a rate of 22%, once a year. George puts $750 in the account as the principal. How can G
Umnica [9.8K]
George shouldn't think too far.

He should use the formula for Compound Interest.

Amount in compound interest, A = P(1+ r/100)ⁿ.

Where A = Amount, P = Principal, r is the rate per year, n = number of years.

Note: the expression (1+ r/100) is raised to power  n.     

From George's problem: P = 750,    r = 22,  I guess number of years , n = x

A(x) = 750( 1 + 22/100)ˣ

A(x) = 750( 1 + 0.22)ˣ 

From your options I can't see an answer. Except the expression of option (A) is actually raised to power x, and not times x as stated in the option.

Determine (without solving the problem) an interval in which the solution of the given initial value problem is certain to exist
Olin [163]

If either t=0 or t=9, the ODE has the trivial solution y=0, but y(1)=1\neq0. So any solution to the ODE that satisfies the initial condition can only exist on the interval 0.
