Y = 10logx

"<span>The sound intensity of rustling leaves is 100 times the reference intensity."
but x = ratio of intensity of sound to reference to intensity, so the x = 100:1 or x = 100

y = 10log(100) = 10 * 2 = 20 decibels

</span>
<span>20 decibels</span>

X=100
Y=10log100
Log100= 2
2x10=20
Y=20 decibels

Which of the following statement(s) describes the rate of change of f over the interval 1.5 ≤ x ≤ 3? Select all that apply.

Vesnalui [34]

2 Answers: Choice B and Choice C

The rate of change is 2.

The rate of change is constant.

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

Explanation:

The first point on the left is when x = 1.5 and it has a height of y = 1

The point (1.5, 1) is on the line.

So is the point (3,4) for similar reasoning.

Compute the slope between those points

m = (y2-y1)/(x2-x1)

m = (4-1)/(3-1.5)

m = 3/(1.5)

m = 2

The slope is 2, which is the same as saying the rate of change is 2. This only applies when x > 1 of which the interval 1.5 ≤ x ≤ 3 is a part of.

Since the slope stays at 2 on the interval 1.5 ≤ x ≤ 3, this means we consider the slope to be constant. If the curve bended at all on this interval, then it wouldn't be a constant slope.

Joe has 2/10 of a dollar. Ashley has 20/100 of a dollar. Billy has 3/100 of a dollar. Together, what fraction of a dollar do the

Vinvika [58]

Answer:

they have 43/100 or 43% out of 100

Step-by-step explanation:

Because joe has 2/10| 2/10=20% or 2

Joe=20

Ashley also has the same thing as joe so 20.

Ashley=20

Billy has 3/100 that = 3 so what's 20+20+3=43 and there's your answer.

Have a great day:)
