Answer:
A logarithm is just an exponent. To be specific, the logarithm of a number x to a base b is just the exponent you put onto b to make the result equal x. For instance, since 5² = 25, we know that 2 (the power) is the logarithm of 25 to base 5. Symbolically, log5(25) = 2.log(a/b) = log a -log b, a > 0, b > 0. log an = n (log a) (Logarithm of a power). logx y = logmy / logmx (Change of base rule).The natural numbers 1, 2, 3,......are respectively the logarithms of 10, 100, 1000, to the base 10. The logarithm of "0" and negative numbers are not defined.The laws apply to logarithms of any base but the same base must be used throughout a calculation. This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB.
Answer:
[(sec^2)(x)]. [e^tan(x)]
Or
[e^(tan(x))]/[(cos^2)(x)].
Step-by-step explanation:
d/dx(e^tan(x))
From the low:
[(d/du)(e^u)]=[(d/du)(u)]. [ln(e)]. [e^u]
=[(sec^2)(x)]. [e^(tan(x))]. [ln(e)]
=[(sec^2)(x)]. [e^(tan(x))]
or
[e^(tan(x))]/[(cos^2)(x)].
Because
(cos^2)(x)=1 / (sec^2)(x)
Pretty sure the equation is 4x-3=63 to solve for X.
1. Add three on both sides to get 4x=63
2. Then divide 4 on both sides, getting x=15
If we plug in d = 0 (to indicate no desserts are ordered), then we'll get
t = 1.4*d + 9.1
t = 1.4*0 + 9.1
t = 9.1
indicating that, on average, the server expects to get $9.10 in tips if no desserts are ordered
This is why the answer is choice D)
