Answer:
see below
Step-by-step explanation:
f(x) = 5x^2 + 2x − 3
(5x-3) ( x+1)
To find the x intercepts, set this equal to zero
0= (5x-3) ( x+1)
Using the zero product property
5x-3 =0 x+1 =0
5x=3 x =-1
x = 3/5 x = -1 are the zeros
End behavior
x = -infinity
5 ( -infinity )^2
5 (infinity) = infinity
as x goes to negative infinity, f(x) goes to infinity
x = infinity
5 ( infinity )^2
5 (infinity) = infinity
as x goes to infinity, f(x) goes to infinity
To plot the function, we need to plot the zeros ( or x intercepts) and the end behavior as well as the vertex to plot the graph
Answer: The radius of the new water tower is approximately 21 ft^3
Step-by-step explanation:
So we know the volume of the Water Tower is 66840 ft^3 and the new one's volume will hold 3/5 as much. so you will multiply 66840 by 3/5 to find the volume of the new one.
66840 * 3/5 = 40104 so the new water tower will hold 40104 cubic feet of water.
Now to find the radius we will use the formula v= 4/3
r^3
40104 = 4/3 * * r^3
40104= 4.1887* r^3
r= 21
Step-by-step explanation:
-2x=30-120
-2x = -90
=x = -90/-2
=x = +45
