Answer:
The formula for exponential growth is f(x)=a(1+r)^x, where a is the initial amount/number, r is the growth rate, and x is the number of years/month/etc. The problem tells us that the initial area is 4500. Every year, it decreases by 7.25%, which is technically -0.0725. "t" is the time. Therefore, we plug in those values into the formula. Then, we have:
f(x) = 4500(1-0.0725)^t
f(x) = 4500(0.9275)^t.
Answer:
the 4th imagen math box
Step-by-step explanation: trust me pleses
<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs
distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:
Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles
Hope this helped :)</span>
Answer:
Step-by-step explanation:
⅓×2
When multiplied by 2 will be;
So you 2×1=2
3×1 is equal to 3
So the final answer will be;
Answer: roots are 2, -2, -3, and 3
Step-by-step explanation:
I'm presuming the equation is x^4-9x^2-4x+12
so first group the equation by factoring out the GCF of the first two terms and last two terms
x^2(x^2-9)-4(x-3)
x^2(x-3)(x+3)-4(x-3)
(x^2-4)(x-3^2)(x+3)
(x-2)(x+2)(x+3)(x-3)^2
So
