Answer:

Yes, it passes the vertical line test.

Step-by-step explanation:

If you can pass a vertical line through the graph, and if it only touches the line ONCE, then it's a function. Otherwise, it's not-- you can't be in two places at 1 time...

In the graph, the area below f(x) is shaded and labeled A, the area below g(x) is shaded and labeled B, and the area where f(x)

Brilliant_brown [7]

Answer:

y < 3x − 1
y ≤ −x + 4

Step-by-step explanation:

As per the given graph we have:

Function f with dotted line (> or < sign), increasing function (slope is positive), y-intercept of -1 and shaded area A is to the right (so < sign), so this represents the inequality:

f(x) < 3x - 1

Function g with solid line (≥ or ≤ sign), decreasing function (slope is negative), y-intercept is 4 and shaded area B is to the left (so ≤ sign), so this represents the inequality:

g(x) ≤ -x + 4

Correct system is C:

y < 3x − 1
y ≤ −x + 4

Find the value of g(25) for the function below. g(x) = 24(x − 39)

rjkz [21]

Answer:

-336

Step-by-step explanation:

g(x) = 24(x − 39)

Let x = 25

g(x) = 24(25 − 39)

= 24 (-14)

= -336

Ted invests $8,310 in a savings account with a fixed annual interest rate of 2% compounded continuously. How long will it take f

Vsevolod [243]

Answer: It will take 8 years.

Step-by-step explanation:

Equation for interest compounded continuously:

$A=Pe^{rt}$ , A = accumulated amount , P=Principal value , r =rate of interest , t= time.

Given: P= $8,310 , r = 2% , A= $9,751.88

$9751.88=8310e^{0.02t}\\\\\Rightarrow\ \dfrac{9751.88}{8310}=e^{0.02t}\\\\\Rightarrow\ 1.17351143201=e^{0.02t}$

Taking natural log on both sides

$\ln (1.17351143201)=\ln (e^{0.02t})\\\\\Rightarrow\ 0.160000478068=0.02t\\\\\Rightarrow\ t=\dfrac{0.160000478068}{0.02}\\\\\Rightarrow\ t=8.0000239034\approx8$

Hence, it will take 8 years.
