The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:

h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms

h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)

The value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

<h3>What is percentage increase ?</h3>

Percentage increase is the amount added to the initial value in the percentage part.

The value of a plot of land which is increases 8% every year has the current value of $350000.

The final value owner wants is $570000. Shanna writes an exponential function of the form, to model the value,v, of the land in t years as,

$v(t)=a\times b^t$

Here, in this exponential function the value of a is fixed or initial term which is $350000 and the value of b is the constant term which is change factor. Here, the value of b is 8%.

b=8%

b=8/100

b=0.08

Thus, the value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

the half life of a medication is the time it takes for the medication to reduce to half of its original amount in a patient's bl

scoray [572]

R=S*0.5^(t/8)
R is the remaining amount 
S is the starting amount (500) 
0.5^ is for the HALF in half-life 
t/8 show that every 8 ts (every 8 hours), it will be halved once 
...so plug in 500mg for the general solution... 
R=(500)*(0.5)^(t/8) 
... plug in 24h to solve for after 24h 
R=(500)*(0.5)^(24/8) 
R=(500)*(0.5)^(3) 
R=(500)*(0.125) 
R=(0.0625) 
...therefore there with be 0.0625 mg of the dose remaining

Brad wants to open a new savings account. He finds one that returns 3% on his investment each year.

Damm [24]

Answer:

1.03x

Step-by-step explanation:

1 year b would be the inital investment added with interest

i believe this is the equation

b = x + r(x)= (1 + r)x

and since it says 3% each year we know its 0.03 (r)
