Hope this helps you out

Answer:

Step-by-step explanation:

Standard form of a circle is given by,

(x - a)² + (y - b)² = r²

Here, (a, b) is the center and 'r' is the radius of the circle.

For a circle having center (8, -4) and radius r = 1

Equation of the circle will be,

(x - 8)² + (y + 4)² = 1²

(x - 8)² + (y + 4)² = 1

Option (1) is the answer.

Question (2)

Circle with the center (-1, 0) and a point (2, -4) on it,

Radius of the circle = Distance between the center and the given point on                                         circumference

                                = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

                                = [tex]\sqrt{(-1-2)^2+(0+4)^2}[/tex]

                                = [tex]\sqrt{9+16}[/tex]

                                = 5

Therefore, equation of the circle will be,

(x + 1)² + (y - 0)² = 5²

(x + 1)² + y² = 25

Answer:

It will take 10.96 hours for 90% of the lead to decay.

Step-by-step explanation:

The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t

This means that the amount can be modeled by the following function:

[tex]A(t) = A(0)e^{-rt}[/tex]

In which A(0) is the initial amount and r is the decay rate.

Has a half-life of 3.3 hours.

This means that [tex]A(3.3) = 0.5A(0)[/tex]. We use this to find r.

[tex]A(t) = A(0)e^{-rt}[/tex]

[tex]0.5A(0) = A(0)e^{-3.3r}[/tex]

[tex]e^{-3.3r} = 0.5[/tex]

[tex]\ln{e^{-3.3r}} = \ln{0.5}[/tex]

[tex]-3.3r = \ln{0.5}[/tex]

[tex]r = - \frac{\ln{0.5}}{3.3}[/tex]

[tex]r = 0.21[/tex]

So

[tex]A(t) = A(0)e^{-0.21t}[/tex]

How long will it take for 90% of the lead to decay?

This is t for which [tex]A(t) = 0.1A(0)[/tex], that is, 100 - 90 = 10% of the initial amount.

[tex]A(t) = A(0)e^{-rt}[/tex]

[tex]0.1A(0) = A(0)e^{-0.21t}[/tex]

[tex]e^{-0.21t} = 0.1[/tex]

[tex]\ln{e^{-0.21t}} = \ln{0.1}[/tex]

[tex]-0.21t = \ln{0.1}[/tex]

[tex]t = -\frac{\ln{0.1}}{0.21}[/tex]

[tex]t = 10.96[/tex]

It will take 10.96 hours for 90% of the lead to decay.

Answer:

<D=<J

Step-by-step explanation:

The first answer is the only correct statement. In geometry, congruent angles are shown through the number of arcs on the vertex of an angle. For example, if two different angles both had three arcs on the vertex, then those two angles are congruent. In this figure, both <D and <J have 4 arcs, which means they are congruent. Additionally, both angles are opposite of a line that measures 25 inches. If two angles are opposite of congruent lines, then the angles are also congruent.

Answer:

The foot of the ladder is

10

feet away from the base of the wall.

Step-by-step explanation:

The distance between building and the bottom of the ladder is option (D) 10 ft

In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Given,

Length of the ladder = 20 foot

Angle between the ladder and the ground = 60  degrees

Draw the figure using the given data

We know,

cos θ = Adjacent side / Hypotenuse

cos 60 = [tex]\frac{x}{20}[/tex]

x = 20 × cos 60

x = 10 ft

Hence, the distance between building and the bottom of the ladder is option (D) 10 ft
