Your taxes went to funding schools will be $2641.The tax is divided into different parts based on the percentage.

A government-mandated contribution to state revenue is placed on employees' wages and corporate earnings or added to the cost of certain products, services, and transactions.

The given data in the problem is;

The market value of the home = is $144,700

They assessed a value of 72% of that amount.

The city has a property tax rate of 0.039.

The assessment value is found as;

$\$ \ 144,700 \times 0.72 = \$ \ 104,184$

The tax on the property will be;

$\$ \ 104,184 \times 0.039 = \$ \ 4,063.176$

The amount which goes to funding schools is;

$\$ \ 4,063.176 \times 0.65= \$ \ 2641.0644$

Hence your taxes went to funding schools will be $2641.

Let f(x) = (x − 3)−2. find all values of c in (1, 4) such that f(4) − f(1) = f '(c)(4 − 1). (enter your answers as a comma-separ

If the function is $(x-3)^{-2}$ and f(4) − f(1) = f '(c)(4 − 1) then there is not any answer.

Given function is $(x-3)^{-2}$ and f(4) − f(1) = f '(c)(4 − 1).

In this question we have to apply the mean value theorem, which says that given a secant line between points A and B, there is at least a point C that belongs to the curve and the derivative of that curve exists.

We begin by calculating f(2) and f(5):

f(2)= $(2-3)^{-2}$

f(2)=1

f(5)= $(5-3)^{-2}$

f(5)=1

And the slope of the function:

$f^{1}$ (x)= $f(5)-f(2)/(5-2)$

$f^{1}$ (c)=0

Now,

$f^{1} (x)=-2*(x-3)^{-3}$

=-2 $(x-3)^{-3}$

-2 is not equal to 0. So there is not any answer.

Hence if the function is $(x-3)^{-2}$ and f(4) − f(1) = f '(c)(4 − 1) then there is not any answer.

A pet store employee measures the lengths of two pet snakes, Noodles and Squiggles. Noodles measures 30 inches long, and Squiggl

deff fn [24]

Answer:

Squiggles

Step-by-step explanation:

steps

convert the length of squiggles from feet to inches
find the difference

1 feet = 12 inches

2 feet = 2 x 12 = 24 inches

length of squiggles = 24 + 10 = 34 inches

squiggles is longer because 34 is greater than 30

difference = 34 - 30 = 4

NikAS [45]

Answer:

Hello, it appears you did not attach an image that would help me answer the question. I would need to see an image of the problem you're working on in order to help you. If you could perhaps insert a photograph of the question or even give me the coordinate of point A, I would be more than happy to help you!

Help! I just started this in school and I am still confused

Tomtit [17]

Okay, to work out the original price, all you have to do is get the sale price ($146.54) and then divide it by 1 - 0.[whatever the percentage is]. In this case, the percentage is 15%, so you do 1 - 0.15 = 0.85.

So to work out the original price, you do:
146.54 ÷ 0.85 = $172.40

The original price is $172.40. :)
