Answer:

2\sqrt{5}+\sqrt{29}+\sqrt{53},\\\approx 17.14\:\mathrm{units}

Step-by-step explanation:

The distance between two coordinates is given by:

d=\sqrt{(\Delta x)^2+(\Delta y)^2}, or d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.

The distance between each of the coordinates of the triangle forms the sides of triangle. Therefore, we can add the distance between these coordinates to find the perimeter of the triangle.

The distance between (3, -2) and (7, 0) is:

d=\sqrt{(7-3)^2+(0-(-2))^2}=\sqrt{4^2+2^2}=\sqrt{20}=2\sqrt{5}

The distance between (3, -2) and (5, 5) is:

d=\sqrt{(5-3)^2+(5-(-2))^2}=\sqrt{2^2+7^2}=\sqrt{53}}

d=\sqrt{(7-5)^2+(0-5)^2}=\sqrt{2^2+5^2}=\sqrt{29}.

Therefore, the total perimeter of the triangle is:

\fbox{$2\sqrt{5}+\sqrt{29}+\sqrt{53}\:\checkmark$}.

When subtracting polynomials,distribute the negative sign,then add.
Doss [256]

Answer:

7m^2 - 11m - 2

Step-by-step explanation:

Subtract (-3m^2 + 10m + 4) from 4m^2 - m + 2:

  4m^2 - m + 2

- (-3m^2 + 10m + 4)   Now distribute the negative sign:

  4m^2 - m + 2

+ 3m^2 - 10m - 4

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

   7m^2 - 11m - 2 is the final answer.

Oksanka [162]
First multiply 20 by .3 (30%)
This will give you a product of 6.
Subtract 6 from 20 (14)
$14 added to $20 is equal to $34
Ramon spent $34 on the pullovers

kati45 [8]

Answer: The height of the tree is 64.94ft

Step-by-step explanation:

Using the trigonometry of angles

Tan theta = opposite/adjacent

Tan 33° = height of the tree/100

Height of the tree= tan 33° * 100

= 0.6494*100

= 64.94ft

The height of the tree is 64.94ft

In the diagram, R, S, and T are all points of tangency. What is the perimeter of Triangle<br> XYZ?
Molodets [167]

Answer:

54 cm

Step-by-step explanation:

Perimeter = TZ + TX + RX + RY + SY + SZ

TZ = 5 cm

TX = 13 cm

RY = 9 cm

RX = TX = 13 cm (tangents drawn from and external point)

SY = RY = 9 cm (tangents drawn from and external point)

SZ = TZ = 5 cm (tangents drawn from and external point)

Plug in the values:

Perimeter = 5 + 13 + 13 + 9 + 9 + 5 = 54 cm
