Evaluate the expression. If necessary, round to the nearest hundredth.
7^log7 23
A. 7
B. 23
C. log7 23

B. 23.

Step-by-step explanation:

In the expression

the logarithm in the exponent is asking us the following question:

"to what power should I raise 7 to as to get 23?"

Let us call that number , then we have

, which means

or

which is Choice B.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
