For the point P (-17,25) and Q(-10,30), fins the distance d(P,Q) and the coordinates of the midpoint M of the segment PQ.

Nonamiya [84]

Answer:

Distance = 8.6

M = (-13.5,27.5)

Step-by-step explanation:

Distance = $\sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2$

= $\sqrt{(-10_ }- (-17)_{ })^2 + (30_{ }- 25_{ })^2$

= $\sqrt{(-10_{ }+ 17_{ })^2 + 5^2_$

= $\sqrt{7^2+5^2}$

= $\sqrt{49+25}$

= $\sqrt{74}$

= 8.6

Midpoint = $(\frac{x_{2}+x_{1}}{2};\frac{y_{2}+y_{1}}{2})$

= (-10+(-17)) ÷ 2 ; (30+25) ÷ 2

= -27 ÷2 ; 55 ÷ 2

= -13.5, 27.5

A rectangular package can be sent through the mail only if the sum of its length and girth is not more than 120". find the dimen

Bingel [31]

Knowing that a square gives the optimum area;

120=s²
√120=s
√2×2×2×5×3=s
2√2×3×5=s
2√30=s

Therefore, the length should be ≈10.95"

Hope I helped :)

What are the values of x, y, and z?

hoa [83]

<h3>To find value of x</h3>

Formula applied:

Exterior angle=Sum of interior angles

Answer:

x=66⁰+45⁰

x=111⁰✔

<h3 />

<h3>To find value of z:</h3>

Formula applied:

Exterior angle=Sum of interior angles

Answer:

119⁰=43⁰+z⁰

119⁰-43⁰=z⁰

z⁰=76⁰✔

<h3>To find value of y:</h3>

∠1+66⁰=180⁰(L.P)

∠1=180⁰-66⁰

∠1=114⁰

Formula used:

Sum of angles of a triangle =180⁰

Answer:

∠ 1+30⁰+y⁰=180⁰

114⁰+30⁰+y⁰=180⁰

y⁰=180⁰-144⁰

y⁰=36⁰✔
