Answer:

scale factor = 2.5

x = 10

Step-by-step explanation:

to find the scale factor, divide 10 by 4.

use the answer and divide it by 25 :)

________

10÷4=2.5

25÷2.5=10

The length of a rectangle is 3 times the width. The perimeter of the rectangle is 56 inches. Determine the width of the rectangl

Phoenix [80]

Answer:

7

Step-by-step explanation:

56/2=28 (since the formula is w x l x 2)

28/4=7

Width is 7 inches and length is 21 inches.

7 + 21 = 28 x 2 = 56

David keeps records of his monthly earnings. Last month he worked 120 hours and earned $2700. This month he worked 100 hours and

lianna [129]

F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300

f(120) = (20 * 120) + 300 = 2400 + 300 = 2700

#6 is the question, are these two functions inverse’s

olya-2409 [2.1K]

I will find the inverse function of f(n) to see if it is g(n).

$f(n) = 2(n - 2)^3$

$y = 2(x - 2)^3$

$x = 2(y - 2)^3$

$(y - 2)^3 = \dfrac{x}{2}$

$y - 2 = \sqrt[3]{\dfrac{x}{2}}$

$y = \sqrt[3]{\dfrac{x}{2}} + 2$

$y = \sqrt[3]{ \dfrac{x}{2} } \times \sqrt[3]{ \dfrac{4}{4}} + 2$

$y = \sqrt[3]{\dfrac{4x}{8}} + 2$

$y = \dfrac{ \sqrt[3]{4x }}{2} + 2$

$g(n) = \dfrac{\sqrt[3]{4n}} {2} + 2$

The inverse function of f(n) is indeed g(n), so f(n) and g(n) are inverse functions.

The graph could be divided up into three different periods of relatively consistent ticket price change: The years 1980 – 1988,

Alex17521 [72]

In time period of 1980-1988 the rate of ticket price is $0.2 per year
Between time period 1989-1993 there is constant rate.
Between year 1994-2011 the increase in rate is same $0.2 per year

The graph could be divided up into three different periods of relatively consistent ticket price change: The years 1980 – 1988, 1989 – 1993 and 1994 – 2011.

<h3>What is Statistic?</h3>

The statistic is the study of mathematics which deal with relations between comprehensive data.

The graph is not available, in the question, so the graph could be as attached
For period 1980-1988
rate of change = 4.2-2.8/ 8 = 0.2
In time period of 1980-1988 the rate of ticket price is $0.2 per year

for period 1989-92 there is a straight line so,
Between time period 1989-1993 there at constant rate.

For period, 1994-2011

rate of change = 4.4-8/17 = 0.2
Between year 1994-2011 the increase in rate is same $0.2 per year

Thus, for the 3 Time period we have rate of change in ticket price is $0.2 per year, no change in ticket price, $0.2 per year respectively.
