Answer:

in 36 years

Step-by-step explanation:

in 36 years, Max will be 54 YEARS OLD and Leo will be 18 YEARS OLD.

54÷18= 3

. Find the value of $1,300 invested at 4.2% interest compounded continuously for 5 years, 9 months. Round your final answer to t
BARSIC [14]
The formula we use for continuous compounding is A=Pe ^{rt} where P is the initial amount invested, r is the rate as a decimal, and t is time in years.  Our P = 1300, our r = .042, and our t = 5.75 (9 months is 3/4 of a year, and 3/4 in a decimal is .75).  Putting all that into our formula we have A=1300(2.718) ^{(.042)(5.75)}.  We have to multiply those 2 powers together and then raise euler's number to it, then multiply by 1300.  Doing all of that, we get the amount at the end to be $1,655.10

What is the answer 5x² – 33x - 14 = 0​
KatRina [158]

Answer:

X=-2/5,7

Step-by-step explanation:

5x² – 33x - 14 = 0​

5x^2-(35-2)x-14=0

5x^2-35x+2x-14=0

5x(x-7)+2(x-7)=0

(5x+2)(x-7)=0

X=-2/5,7

so the value of X is -2/5,7
