Answer:

5*10^10

Step-by-step explanation:

10 to the power of 10 is 10^10.

10^10*9 is 90000000000

10^10*4 is 40000000000

90000000000-40000000000=50000000000

5*10^10

Ivanshal [37]

Answer: The number 12 represents admission charge in Mariana's equation.

Step-by-step explanation:

As per given ,

Total cost = ( Charge per ticket) (Number of tickets) +  (Admission fees)  (i)

For x = Number of tickets, the total cost (c) for a day at the amusement park is given as

c = 1.50x + 12                                       (ii)

Here, 12 = Admission fees                 [Comparing (i) and (ii)]

Hence, the number 12 represents admission charge in Mariana's equation.

which function rule is represented by the tablex 0 1 2 3y 0 -7 -14 -21a y= 7xb y= -7xc y= x-8d y= 7x-14
salantis [7]

The answer is y = -7x

Expalnation

Two points on the table are (0,0) and (1,-7)

Change in y = -7-0 = -7

Change in x = 1-0 = 1

Slope m of the function = -7/1= -7

Using y= mx + c

Picking point (0,0), x = 0, y = 0

y = mx + c becomes

0 = -7(0) + c

0 = 0 + c

c= 0

Hence, the equation is y = -7x + 0

which is y = -7x

Option b is the correct answer

Condensing Logarithmic Expression In Exercise,use the properties of logarithms to rewrite the expression as the logarithm of a s
nevsk [136]

Answer:

[ln \frac{x(x^2 + 1)}{(x + 1)}]^\frac{3}{2}

Step-by-step explanation:

\frac{3}{2} [ln x(x^2 + 1) - ln(x + 1)]

ln(m/n)= lnm - ln(n)

\frac{3}{2}[ln x(x^2 + 1) - ln(x + 1)]

\frac{3}{2}[ln \frac{x(x^2 + 1)}{(x + 1)}]

3/2 is before ln. so we move the fraction 3/2 to the exponent

as per log property we move the fraction to the exponent

[ln \frac{x(x^2 + 1)}{(x + 1)}]^\frac{3}{2}
