The measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.

<h3>How to find the length of a Line segment?</h3>

The formula for the length of the line segment is;

d = √[(x2 − x1)² + (y2 − y1)²]

We are given the coordinates of Line segment PQ as;

P (-4.-9) and Q (4 -3)

Thus, distance of line segment PQ is;

d = √[(4 − (-4))² + (-3 − (-9))²]

d = √(64 + 36)

d = √100

d = 10

Thus, we can say that the measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.

what are a) the ratio of the perimeters and b) the ratio of the areas of the larger figure to the smaller figure? the figures ar

Alla [95]

We know that

a) find <span>the ratio of the perimeters
</span><span>
the ratio of the perimeters is equal to the scale factor
</span>scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3

b) find <span>the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]</span>²*area smaller figure
scale factor²=area larger figure/area smaller figure

the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9

the answer Part b) is
169/9

the complete answer is
13/3 and 169/9

Given f(x) = 7x^9, find f^-1 (x). Then state whether f^-1 (x) is a function

Olin [163]

A though without graphing software it would appear to be C

Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 7x^9
x = 7y^9
x/7 = y^9
(9)√(x/7) = y
This is a ninth root of (x/7) also written in exponents as y = (x/7)^(1/9).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.

A laptop has a listed price of $699.99 before tax. If the sales tax rate is 6.75%, find the total cost of the laptop with sales

Nookie1986 [14]

The total cost of the laptop with sales tax included is to the nearest cents is 747.24 dollars.

<h3>What is sales tax?</h3>

A sales tax is a consumption tax imposed by the government on the sale of goods and services

In other words, sales tax is an amount of money, calculated as a percentage, that is added to the cost of a product or service when purchased by a consumer at a retail

A laptop has a listed price of $699.99 before tax.

The sales tax rate is 6.75%.

Total cost of the laptop with sales tax included can be calculated as follows:

sale tax = 6.75% of 699.99

sale tax = 6.75 / 100 × 699.99

sale tax = 4724.9325 / 100

sale tax = 47.249325 dollars

Therefore,

Total cost of the laptop with sales tax included = 47.249325 + 699.99 = 747.239325 dollars = 747.24 dollars.
