Answer:

x = 0.135 ( 3 dec. places )

Step-by-step explanation:

Using the law of logarithms

• log_{b} x = n ⇔ x = b^{n}

Note that ln x = log_{e} x

given

ln x = - 2 ⇒ x = e^{-2} ≈ 0.135

Write an exponential function in the form y=ab^x that goes through points (0,12) and (3,6144)
skad [1K]

Given:

An exponential function goes through points (0,12) and (3,6144).

To find:

The exponential function.

Solution:

The general exponential function is:

y=ab^x           ...(i)

The function goes through point (0,12). Substituting x=0,y=12, we get

12=ab^0

12=a

The function goes through point (3,6144). Substituting a=12, x=3,y=6144 in the general exponential function, we get

6144=12b^3

\dfrac{6144}{12}=b^3

512=b^3

512^{\frac{1}{3}}=b

8=b

Putting a=12,b=8 in (i), we get

y=12(8)^x

Therefore, the required exponential function is y=12(8)^x.

Can somebody help and explain this plzz
8_murik_8 [283]
A) Every T is worth 7 points, and every F is worth 3 points.  So if we let T = 7 and F = 3, we can count how many T's and F's each team scored and write it as an expression.


So for the East Side Bulldogs, they have 7 touchdowns and 6 field goals, thus the expression for them is:

7T + 6F

For the West Side Bulldogs, they have 5 touchdowns and 5 field goals, thus the expression for them is:

5T + 5F

B) The difference would be written as:
7T + 6F - (5T + 5F) = 2T + F

C) To determine how many more points the winning team has than the losing team, calculate the scores of the two teams.  Then subtract the smaller number from the larger number to determine the score differential.
