Ulleksa [173]

Answer:

Step-by-step explanation:

y=a(1+r/c)^{ct}\\ \\ y=9000(1+.042/12)^{12t}\\ \\ y=9000(1.0035)^{12t}\\ \\ a)\ y=9000(1.0035)^{12(10)}=\$ 13687.61\\ \\ b)\ 15400=9000(1.0035)^{12t}\\ \\ 1.0035^{12t}=77/45\\ \\ 12t ln(1.0035)=ln(77/45)\\ \\ t=(ln(77/45))/(12ln(1.0035))\\ \\ t\approx 12.8\ years

What are the x-intercepts of the graph of the quadratic function f(x) = 3(x − 1)(x + 3)?
creativ13 [48]

Answer:

-3, 1

Step-by-step explanation:

f(x) = 3(x − 1)(x + 3)

To find the x intercepts, set the equation equal to zero

0 = 3(x − 1)(x + 3)

Using the zero product property

x-1 = 0     x+3 =0

x=1            x=-3
