Answer:
40
Step-by-step explanation:
a^2+b^2=c^2
therefore c^2-b^2=a^2
41x41=1681
9x9=81
1681-81=1600
Sqrt1600=40
This shows that both functions have the same y-intercept
<h3>Polynomial and exponential functions</h3>
Given the following functions as shown:
f(x) = -x^2 + 2x + 1
g(x) = 2^x
The y-intercept occurs at x = 0
For f(x) = -x^2 + 2x + 1
f(0) = -0^2 + 2(0) + 1
f(0) = 1
For the g(x), the y intercept is caculated as:
g(0) = 2^0
g(0) = 1
This shows that both functions have the same y-intercept

Answer:
The length of each side of the square park is 2,400 ft
Step-by-step explanation:
we know that
The scale is 
step 1
Remember that
1 ft=12 in
The length of each side on the map is 1 ft
Convert ft to in
1 ft=1(12)=12 in
step 2
Find the length of each side of the square park
using proportion
Let
x ----> the actual length of each side of the square park

The variable t represents the number of seconds that have passed after the release of the rocket.
<h3>
Function</h3>
The function can be defined as an expression that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The height of a rocket a given number of seconds after it is released is modeled by,

As given in the above function, h (height) is the dependent variable which depends on the number of seconds t after the rocket is released (independent variable).
Hence we can conclude that the variable t represents the number of seconds after the rocket has been released.
