Nady [450]3 years ago
5 0

Answer:

3, 7

Step-by-step explanation:

"Zeros" means solutions to the equation f(x) = 0.  In other words, what are the values of  x  that make the function's value equal to zero?

This one can be solved by factoring.

x^2-10x+21=0\\(x-7)(x-3)=0\\x-7=0 \text{ or } x-3=0\\x=7 \text{ or } x=3

Andre45 [30]

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.
