Answer:

B and D

Step-by-step explanation:

$\frac{5}{6}$ × 13 = $\frac{5(13)}{6}$ = $\frac{65}{6}$ = 10 $\frac{5}{6}$ < 13

4 × 13 = 52 > 13

$\frac{3}{4}$ × 13 = $\frac{3(13)}{4}$ = $\frac{39}{4}$ = 4 $\frac{3}{4}$ < 13

$\frac{10}{10}$ × 13 = 1 × 13 = 13

Band D are equal to or greater than 13

What is the correct inverse function for f(x)=ln(3x)?

Maslowich

Let y = f(x)

y = ln(3x)

Exchange place with x and y.

x = ln(3y)

Solve for y.

y = (e^x)/3

Replace y with the inverse notation.

f^(-1) x = (e^x)/3

Done.

Using the quadratic formula, what is the value of x for x^2-4+5=0

PSYCHO15rus [73]

value of x is: x= i and x= -i

Step-by-step explanation:

We need to find the value of x from $x^2-4+5=0$ using quadratic formula.

The term is: $x^2+1=0$

The quadratic formula is:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\$

Where a = 1, b=0,c=1

Putting values:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{0\pm\sqrt{(0)^2-4(1)(1)}}{2(1)}\\x=\frac{\pm\sqrt{-4}}{2}\\x=\frac{\pm2i}{2}\\x=\pm i$

So, value of x is: x= i and x= -i
