6 0

By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

<em><u>Recall:</u></em>

Trigonometry ratios that can be used to solve a right triangle are: SOH CAH TOA.

SOH represents: sin ∅ = Opp/Hyp

CAH represents: cos ∅ = Adj/Hyp

TOA represents: tan ∅ = Opp/Adj

The diagram attached below depicts the problem given.

∅ = x

Opp = 15 ft

Hyp = 50 ft

Thus, applying the trigonometry ratio, SOH, we have:

sin x = 15/50

x = $sin^{-1}(15/50)$

x = 17.5°

In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options. The radius of the cir

FromTheMoon [43]

The statements which are correct about the equation of circle $x^{2} +y^{2}-2x-8=0$ are 1) The radius of the circle is 3 units,2) The center of the circle lies on the x axis,5) The radius of this circle is the same the radius of the circle whose equation is $x^{2} +y^{2} =9$ .

Given the equation of circle be $x^{2} +y^{2}-2x-8=0$ .

We are required to find the appropriate statements related to the equation $x^{2} +y^{2}-2x-8=0$ .

$x^{2} +y^{2}-2x-8=0$ can be written as under:

$x^{2} +y^{2} -2x+1-9=0$

$x^{2} +1^{2}-2x+y^{2} -9=0$

$(x-1)^{2}+y^{2}$ -9=0

$(x-1)^{2} +y^{2} =9$

$(x-1)^{2}+y^{2} =3^{2}$

Equation of a circle usually in the form $x^{2} +y^{2} =a^{2}$ in which a is radius.

From the comparison of both the equations we get that radius is 3 units.

From the equation point will be (1,0). It is on the x axis.

Hence the statements which are correct about the equation of circle $x^{2} +y^{2}-2x-8=0$ are 1) The radius of the circle is 3 units,2) The center of the circle lies on the x axis,5) The radius of this circle is the same the radius of the circle whose equation is $x^{2} +y^{2} =9$ .

(0, 1) , (4, 2) equation in slope intercept form

mihalych1998 [28]

Answer:

2=1/4(4+b)

Step-by-step explanation:

(0,1), (4,2)

first, find the slope

slope formula- (y2-y1)/(x2-x1)

plug in the coordinates

(2-1)/(4-0)

subtract

1/4

slope=1/4

slope intercept form- y=mx+b

choose one of the coordinates to plug in

(4,2)

plug it in

2=1/4(4+b)
