Answer:

14 units

Step-by-step explanation:

Solution:-

A(5,1)B(7,1)

\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2}    }

AB=\sqrt{(7-5)^{2} +(1-1)^{2} }

= \sqrt{2^{2} } =2

BC=\sqrt{7-7^{2}+(6-1)^{2}  }

=\sqrt{5^{2} } =5

perimeter=2(AB)+2(BC)

= 2(2)+2(5)\\

= 4+10= 14

-----------

hope it helps...

have a great day!!

slamgirl [31]

The given question have mistake. The correct question is written below.

Question:

A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?

Answer:

Option B:

h(t)=-4.9 t^{2}+6.37t

Solution:

<u>General formula for the height of the projectile over time:</u>

(1) h(t)=-16 t^{2}+v t+s

Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)

(2) h(t)=-4.9 t^{2}+v t+s

Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)

Given initial velocity = 6.37 s and initial height is 0.

The height of the dog is in meters.

So, use second formula and substitute v = 6.37 and s = 0.

h(t)=-4.9 t^{2}+v t+s

h(t)=-4.9 t^{2}+6.37t+0

h(t)=-4.9 t^{2}+6.37t

Hence option B is the correct answer.

Which is true about the slope of a line?
Inessa05 [86]

Answer:

Step-by-step explanation:

The slope of all lines in quadrant 1 is positive. FALSE

The slope of a line does not depend on the quadrant.

The slope of <u>all lines</u> that pass through the origin is undefined.FALSE

The slope of some lines that pass trough the origin are undefined ( lines that are vertical have undefined slope)

The larger the slope, the longer the line.FALSE

The lines do not get longer or shorter because they go to infinity in both directions.

The larger the magnitude of the slope value, the steeper the line. TRUE

The larger the absolute value of the slope the steeper the slope.
