The percent discount is 30%.
If you multiply $32 by .30, you will get $9.60. That is the amount of the discount. If you subtract $9.60 from $32, you will get $22.40 which is what he paid before tax. Therefore the percent discount is 30%.

Kelly used the vertical line test to determine whether or not the curve that she
Keith_Richards [23]
<h3>Answer:  Choice D</h3>

All vertical lines intersected the curve at exactly 1 point.

===========================================================

Explanation:

If there is a case when a single vertical line crosses 2 or more points on the  curve, then it will not be a function. In this situation, it is said that the curve fails the vertical line test.

Passing the vertical line test means that every vertical line passes through exactly one point on the curve. Each x input leads to exactly one output. If such a situation happens, then we have a function.

Since Kelly concluded that the curve is a function, this means the curve passed the vertical line test, and it points us to choice D as the answer.

Solve log x = 2.
Sever21 [200]

Answer:

If log x = 2

x = 100

Step-by-step explanation:

Logarithm always has a base and an index. It can be I many forms.

It can be in base 2, 3, 4, 5, and so on.

It is a property of logarithm that if

logarithm of 'a' to base 'b' equals 'x', we write:

log_b (a) = x

Then,

a = b^x.

Usually, when a logarithm is written without a base, it tells us that it is in base 10. Instead of writing a logarithm of x to base 10,we can just write 'log x', it is sufficient to say that it is in base 10.

It can also be in the form of the Napierian Logarithm, 'ln'.

'ln x' is logarithm to base 'e'.

if ln x = 5

Then

x = e^5.

So,

log x = 2

Means logarithm of 'x' to base 10 equals 2.

x = 10^2

= 100

x = 100
