Answer:

52 units

Step-by-step explanation:

Plot the points and connect.

Note. If you connect the points in the given order you will end up with a weird figure hence we connect as pictured.

Horizontal sides sum to:

2*(8 - (-7)) = 2*15 = 30

Vertical sides sum to:

2*(8 - (-3)) = 2*11 = 22

The perimeter is:

30 + 22 = 52

PLZ HLP Given the equation 5x + y = 7, which equation below would cause a consistent-independent system?

DanielleElmas [232]

Answer:

the equation D ) would cause a consistent-independent system.

Step-by-step explanation:

A ) 5 x + y = 7 /*( -2 )

10 x + 2 y = 14

--------------------

- 10 x - 2 y = - 14

10 x + 2 y = 14

------------------------

0 x = 0 ( Dependent system )

B ) 5 x + y = 7 / * 3

- 15 x - 3 y = - 6

--------------------------

15 x + 3 y = 21

- 15 x - 3 y = - 6

-------------------------

0 x = 15 ( Inconsistent system )

C ) 5 x + y = 7

5 x + y = - 7 / * ( - 1 )

---------------------------

5 x + y = 7

- 5 x - y = 7

------------------

0 x = 14 ( Inconsistent system )

D ) 5 x + y = 7 / * ( - 2 )

6 x + 2 y = 7

------------------

- 10 x - 2 y = - 14

6 x + 2 y = 7

-----------------------

- 4 x = - 7; x = 7/4; y = - 7/4

Suppose quantity s is a length and quantity t is a time. Suppose the quantities v and a are defined by v = ds/dt and a = dv/dt.

finlep [7]

Answer:

a) $v = \frac{[L]}{[T]} = LT^{-1}$

b) $a = \frac{[L}{T}^{-1}]}{{T}}= L T^{-1} T^{-1}= L T^{-2}$

c) $\int v dt = s(t) = [L]=L$

d) $\int a dt = v(t) = [L][T]^{-1}=LT^{-1}$

e) $\frac{da}{dt}= \frac{[L][T]^{-2}}{T} = [L][T]^{-2} [T]^{-1} = LT^{-3}$

Step-by-step explanation:

Let define some notation:

[L]= represent longitude , [T] =represent time

And we have defined:

s(t) a position function

$v = \frac{ds}{dt}$

$a= \frac{dv}{dt}$

Part a

If we do the dimensional analysis for v we got:

$v = \frac{[L]}{[T]} = LT^{-1}$

Part b

For the acceleration we can use the result obtained from part a and we got:

$a = \frac{[L}{T}^{-1}]}{{T}}= L T^{-1} T^{-1}= L T^{-2}$

Part c

From definition if we do the integral of the velocity respect to t we got the position:

$\int v dt = s(t)$

And the dimensional analysis for the position is:

$\int v dt = s(t) = [L]=L$

Part d

The integral for the acceleration respect to the time is the velocity:

$\int a dt = v(t)$

And the dimensional analysis for the position is:

$\int a dt = v(t) = [L][T]^{-1}=LT^{-1}$

Part e

If we take the derivate respect to the acceleration and we want to find the dimensional analysis for this case we got:

$\frac{da}{dt}= \frac{[L][T]^{-2}}{T} = [L][T]^{-2} [T]^{-1} = LT^{-3}$
