Answer:

  28k

Step-by-step explanation:

The perimeter is the sum of the four equal-length sides:

  P = 7k +7k +7k +7k

  P = k(7 +7 +7 +7)

  P = 28k . . . . perimeter of the rhombus

__

Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.

y=1-i

x=-3/2-i/2

Answer:

x = 4

Step-by-step explanation:

(7x - 2) + (3x + 9) = 10x + 7

(10x + 7) + (8x - 6) = 18x + 1

18x + 1 = 73

18x = 72

72/18 = x

x = 4

Answer:

just use the pie sign in your calculator

pi = 3.1415926535898

This is something you either memorize, have on a flashcard, or just let your calculator handle the details. The digits of pi are effectively random and do not repeat with a known pattern.

The correct format of the question is

At the end of 2006, the population of Riverside was 400 people. The population for this small town can be modeled by the equation below, where t represents the number of years since the end of 2006 and P represents the number of people. [tex]P = 400 ( 1.2 )^ t[/tex] Based on this model, approximately what was the increase in the population of Riverside at the end of 2009 compared to the end of 2006?

(A) 291

(B) 691

(C) 1040

(D) 1440

Answer:

The increase in the population at the end of 2009 is 291 people

Step-by-step explanation:

We are given the equation as [tex]P = 400 ( 1.2 )^ t[/tex]

where

P = No of People

t= No of Years

it is given that in the year 2006 the population is 400

this will only happen when we take t= 0

so for

Year    value of t

2006-    t = 0

2007-    t  = 1

2008-    t = 2

2009     t = 3

No of people in 2009 will be

[tex]P = 400(1.2)^3[/tex]

     = 400*1.728

   P  = 691.2

Since the equation represents no of people so it can't be in decimals, Therefore the population will be 691

Increase = P(2009) - P(2006)

               = 691 - 400

                = 291

The increase in the population at the end of 2009 is 291 people.

Answer:

(5, 0)

Step-by-step explanation:

For the first line, we can isolate x by subtracting 5y on both sides.

x=5-5y.

Now we can use substitution on the second line!

-(5-5y)+6y=-5

= -5+5y+6y=-5

=-5+11y=-5

=11y=0

y=0  

We subsitute y for the first line,

x+5(0)=5

x+0=5

x=5

We can check our work by plugging in x and y

5+5(0)=5 ✔

-5+6(0)=-5 ✔

Step-by-step explanation:

y-1 =-3x-12

Equation of a line is y=mx+c

y=-3x-12 +1

y= -3x -11

parallel lines men you can use the same gradient so e,g y=-3x+12

Answer:

the last one and the second one I think. Maybe the first one not very sure.

Answer: x=36 degrees

Step-by-step explanation:

Angle EAF and FAB must equal 180 degrees together as all straight lines do. 36 times 3= 108 degrees so 3x=108 degrees. 36 times 2= 72 degrees so 2x=72 degrees. Therefore, 3x+2x=180 degrees.

If you know about the power rule,

d/dw (2w² + 1) = 2 d/dw (w²) = 2 • 2w = 4w

If you have to use the limit definition of the derivative, let f(w) = 2w² + 1. Then

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{f(w+h)-f(w)}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{(2(w+h)^2+1)-(2w^2+1)}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{2(w^2+2wh+h^2)-2w^2}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}\frac{4wh+2h^2}h[/tex]

[tex]f'(w)=\displaystyle\lim_{h\to0}(4w+2h)=\boxed{4w}[/tex]

AnswerStep-by-step explanation:

[tex] \frac{5}{12} = \frac{170}{} [/tex]

[tex] \frac{5}{12} = \frac{5 \times 34}{12 times 34} [/tex]

Simplify

Complete question :

A parachutist's speed during a free fall reaches 162 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.

Answer:

45 m/s ; 900 meters

Step-by-step explanation:

Given that :

Speed = 162 kilometers per hour ;

The speed in meters per second can be found by:

162 km/hr = (162 * 1000)m / (60 * 60) second

162 km/hr = 162000m / 3600 s

162 km/hr = 45 m/s

At this speed, how many meters will the parachutist fall during 20 seconds of free fall?

Speed of free fall = 45m /s

Distance in meters after 20 seconds :

(45 m/s * 20s) = 900 meters

The range of the set of ordered pairs are [tex]Y =\{-1,-7,-11,-15\}[/tex].

Step-by-step explanation:

Let [tex](x,y)[/tex] be an ordered pair, where [tex]x[/tex] corresponds to an element of the domain and [tex]y[/tex], an element of the range. Hence, the range of the set of ordered pair are:

[tex]Y =\{-1,-7,-11,-15\}[/tex]

The range of the set of ordered pairs are [tex]Y =\{-1,-7,-11,-15\}[/tex].

Answer:

3.125 inches would result in 122 miles.

Step-by-step explanation:

We can figure this out using proportions.

[tex] \frac{20 \: miles}{ \frac{1}{2} \: inches} = \frac{x}{3.125 \: inches} \\ \\ \frac{ \frac{1}{2}x }{ \frac{1}{2} } = \frac{62.5}{ \frac{1}{2} } \\ \\ x = 122[/tex]

122 miles would be the answer.

Answer:

125 miles

Step-by-step explanation:

[tex]\frac{20}{\frac{1}{2}}=\frac{x}{3.125}\\x=40 \times 3.125=125 \\x=125~miles[/tex]
