Answer:

13 units

Perimeter is 11.31 units

Step-by-step explanation:

To find the distance between two points, we use the distance formula

d=\sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }.  

Chose a point to be (x_1,y_1) and another point to be (x_2,y_2).

Let the origin (0,0) be (x_1,y_1) where x_1=0\\y_1=0.

Let (-5,-12) be (x_2,y_2) where x_2=-5\\y_2=-12.

Substitute the values.

d=\sqrt{((-12-0)^{2}+(-5-0)^{2} }\\d=\sqrt{((-12)^{2}+(-5)^{2} }\\d=\sqrt{144+25}=\sqrt{169} =13

The perimeter is found by finding the distance of each side and adding it together. Since it has all equal sides, it will be the same distance for all sides. We will find the distance of just one side from point D to A.

Let the point D the origin (0,0) be (x_1,y_1) where x_1=0\\y_1=0.

Let the point A (2,2) be (x_2,y_2) where x_2=2\\y_2=2.

Substitute the values.

d=\sqrt{((2-0)^{2}+(2-0)^{2} }\\d=\sqrt{(2)^{2}+(2)^{2} }\\d=\sqrt{4+4}=\sqrt{8} =2.83

Perimeter = 2.83+2.83+2.83+2.83= 11.31 units

How many halves are in three wholes
vlabodo [156]

Answer:

6

Step-by-step explanation:

1/2 + 1/2 = 1

1/2 + 1/2 = 1

1/2 + 1/2 = 1

There are 6 halves that equal 3.

Another way to do this is:

1/2x = 3

3 / 1/2 = 6

x = 6

Determine the value of a + b in the system of equations below. <br><br> 5a + 4b = 22<br> 7a-b= 11
dexar [7]

Answer:

We have a + b as;

2 + 3 = 5

Step-by-step explanation:

Here, we want go get the value of a and b

from the second equation, we can get an expression for b

We have this as;

7a - b = 11

Thus,

b = 7a - 11

Now, from here, we can substitute the value of b into the first equation

We have this as;

5a + 4(7a - 11) = 22

5a + 28a -44 = 22

33a = 22 + 44

33a = 66

a = 66/33

a = 2

Recall;

b = 7a - 11

substituting the value of a from above;

b = 7(2) - 11

b = 14 - 11

b = 3

What is the unknown fraction? <br><br>6/10 + ____ = 62/100​
sergeinik [125]
The answer is 2/100 or 1/50!

6/10 is equivalent to 60/100.
62/100 - 60/100 = 2/100 = 1/50

So, 6/10 + 1/50 = 62/100
6/10 + 2/100 = 62/100

(Use 1/50 because that’s the simplified answer!)

I hope this made sense! Good luck!

The answer is f(x) will eventually exceed g(x) because f(x) is an exponential function.
