It would be 50

130+180= 310

360-310= 50

You get 180 from the missing side by 70 that becomes 180.

Drop the egg from half way up the building. This divides the search space in half. If it breaks, start on the bottom floor and work your way up the top :) Hope it works

у X -7 -5 -5 -4 -3 -2 ברן 4 LO- To 2 -3 -6 -7 In this graph, the v-intercept of the line is 1. The equation of the line is v=​
GREYUIT [131]

Answer:

The y intercepts is -2

y = 1x-2

Step-by-step explanation:

The y intercept is where it crosses the y axis

The y intercepts is -2

We need to determine the slope, by using to points on the line

(0,-2) and (2,0)

m = (y2-y1)/(x2-x1)

   = (0 --2)/(2-0)

   = (0+2)/(2-0)

   = 2/2

  = 1

The equation for the line is

y = mx+b where m is the slope and b is the y intercept

y = 1x-2

Earth is represented on a map of a portion of the solar system so that its surface is the circle with equation x2+y2+8x+2y−4883=
vodka [1.7K]

Answer:

The general form of the equation for the orbit of the satellite is x^{2}+y^{2}+8\cdot x+2\cdot y = 4939.16.

Step-by-step explanation:

From statement we have the general equation of the elliptic form of Earth. First we have to transform this formula to the standard form of the equation of the circle. That is:

1) x^{2}+y^{2}+8\cdot x +2\cdot y -4883=0 Given

2) (x^{2}+8\cdot x)+(y^{2}+2\cdot y) = 4883 Associative, commutative and modulative properties/Compatibility with addition/Existence of additive inverse.

3) (x^{2}+8\cdot x +16)+(y^{2}+2\cdot y+1)-17=4883 Associative, commutative and modulative properties/Compatibility with addition/Existence of additive inverse.

4) (x+4)^{2}+(y+1)^{2} = 4900 Square perfect trinomial/Result

According the result, the center of Earth is C(x,y) = (4, 1) and the square of the radius of Earth equals 4900. That is: r = 70

If satellite circles 0.4 unit above Earth, then the equation of the orbit of the satellite is:

(x+4)^{2}+(y+1)^{2}=70.4^{2}

(x+4)^{2}+(y+1)^{2} = 4956.16

Now we transform this into its general form:

1) (x+4)^{2}+(y+1)^{2} = 4956.16 Given

2) x^{2}+8\cdot x +16+y^{2}+2\cdot y+1 = 4956.16 Square perfect trinomial

3) x^{2}+y^{2}+8\cdot x+2\cdot y = 4939.16 Associative, commutative and modulative properties/Compatibility with addition/Existence of additive inverse/Result

The general form of the equation for the orbit of the satellite is x^{2}+y^{2}+8\cdot x+2\cdot y = 4939.16.
