Express 3^2 = x as a logarithmic equation.

1 answer:

8 0

Taking the log of both sides of the equation, you have
$2\log(3)=\log(x)$
Dividing by log(3), this looks like the change of base formula.
$\log_a(b)=\dfrac{\log(b)}{\log(a)}$

That is, division by log(3) gives
$2=\dfrac{\log(x)}{\log(3)}\\\\2=log_3(x)$

This apparently matches your first choice:
log3(x) = 2

Ephemeral services corporation (esco) knows that nine other companies besides esco are bidding for a $900,000 government contrac

EastWind [94]

Answer:

c. $100,000

Step-by-step explanation:

Calculation of the expected net profit of Ephemeral services corporation

Since we are been told that 9 other companies besides esco are as well bidding for the $900,000 government contract, it means we have to find the expected net profit by dividing 1 by 9×$900,000 .Thus ESCO can only expect to cover its sunk cost.

Hence ,

E(X) = (1/9) × $900,000

E(X)=0.111111111×$900,000

E(X)= $100,000

Therefore the expected net profit would be $100,000

Add using the number line. −0.5 + (−1.7)

Rudik [331]

Answer:

- 0.5 - 1.7 = - 2.2

Step-by-step explanation:

We need to add two numbers using the number line.

Steps to Add Numbers on the Number Line:

When we add a negative numbers that we move the point to the left of the number line.

We are adding two negative numbers. Locate the first number which is -0.5. Then, add negative 1.7 to it which means moving the existing point 1.7 units to the left of the number line.

So, we get 2.2 on the left.

2.2 is left side it means sign is negative.

Final answer is -2.2
