The center of the circle will be equal to (-3,4) equation of the circle   x²+y²+6x-8y+16=4

The circle is defined as the locus of the point traces around a fixed point called as the center and is equidistant from the out trace.

The general form of the equation of the circle is:-

(x-x₁)²+(y-y₁)²=r²

here x1 and y1 are the center of the circle

Now we will convert our equation in the general form:-

x²+y²+6x-8y+16=4

x²+6xy²-8y+16-4=0

x²+3x+3x+9-9+y²-4y-4y+16-16-4=0

(x+3)²+(y-4)²-9-16+16-4=0  (x+3)²+(y-4)²=13

By comparing with the general form we can see that the coordinate of the center of the circle will be {-3,4)

Step-by-step explanation:

The height of the kite above the ground to the nearest tenth of a foot is 84.1 ft

The situation forms a right angle triangle.

Therefore, the length of the string is the hypotenuse of the triangle formed.

Hence, using trigonometric ratios,

sin 35 = opposite / hypotenuse

sin 35 = h / 140

cross multiply

h = 140 sin 35

h = 140 × 0.57357643635

h = 80.3007010891

Height of the kite above the ground = 80.3007010891 + 3.75 = 84.0507010891

Height of the kite above the ground = 84.1 ft

========================================================

Explanation:

We'll use the following facts (either memorized or written on a reference sheet somewhere)

Each of those equations will form conversion factors to help us go from km/hr to m/s. Each conversion factor is a fraction connecting the two sides of the equation. Example: The equation 1000 m = 1 km forms the conversion factor of [tex]\frac{1000 \text{ m}}{1 \text{ km}}[/tex]

In choice B, notice how the fractions are set up. The "km" units cancel when dividing. The same goes for the "hr" and "min" units.

Check out the screenshot below where I show this cancellation in action. The color-coding helps show how the terms pair up and cancel.

Choice A comes close to what choice B is saying, but we don't have the "min" units cancel. So choice A is eliminated as an answer.

Choices C and D are also eliminated because of the "75 km" in the denominator. It should be 1 km.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

A.) The distance between the boat and the lighthouse when the angle of depression is 10°.

Tan(10°) = Height of lighthouse/ distance between the boat and the lighthouse

Distance between the boat and the lighthouse

= 145/Tan(10°) = 822.336ft

B.) The distance between the boat and the lighthouse when the angle of depression is 68°.

Tan(68°) = Height of lighthouse/ distance between the boat and the lighthouse

Distance between the boat and the lighthouse

= 145/Tan(68°) = 58.584ft

The distance between point A and B = 822.336ft - 58.584ft = 763.752 ft

Hence, the distance from point A to point B is 763.752ft.

Step-by-step explanation:

there is no image here. and we don't know, if B is smaller or lager than A.

anyway, the volume of a sphere is

4/3 × pi × r³ = 4/3 × pi × r×r×r

that means the scale factor applying to r (radius) has to be multiplied in 3 times (with every r). so, to compare the volumes, the volume scale factor is cubed the linear scale factor.

44³ = 85184

if B is smaller, then its volume is 50/85184 m³

if B is larger, then its volume is 50×85184 m³

since this a such a big number, you made possibly a typo with the scale factor.

The volume of sphere B, the image of sphere A after dilation by a scale

factor of 44, is approximately 1,223,762.42 cubic meters.

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Since, The volume of a sphere is given by the formula:

V = (4/3) pi r

where V is the volume, pi is the constant 3.14.., and r is the radius of the sphere.

Since, sphere A has a volume of 50 cubic meters, we can use this formula to solve for its radius:

50 = (4/3) pi r

r = (3/4)  (50 / pi)

r = (3/(4pi) 50)^(1/3)

r = 2.67 meters

Note that we know,

The radius of sphere A, we can use the scale factor of 44 to find the radius of sphere B:

rₐ = 44  rₓ

rₐ = 44 × 2.67

rₐ = 117.48 meters

Finally, we can use the volume formula again to find the volume of sphere B:

V(B) = (4/3) pi rₓ

V (B) = (4/3) pi (117.48)

V (B) = 1,223,762.42 cubic meters

Therefore, the volume of sphere B, the image of sphere A after dilation by a scale factor of 44, is approximately 1,223,762.42 cubic meters.

Answer:

Alice's age = 5 years

Malice's age = 5 years

Bob's age = 5+8 =13 years

Step-by-step explanation:

Let x be the age (in years of Alice and Malice (They have the same age because they are twins).

Age of Bob: x+8  (because he is 8 years older than the twins).

Then the sum of their three ages is 23:

x (Alice's age) + x (Malice's age) +(x+8 ) (Bob's age)= 23

2x + ( x+8) = 23

3x+8 = 23

3x = 15

(3x)/3 = 15/3

x = 5

So ...

Alice's age = 5 years

Malice's age = 5 years

Bob's age = 5+8 =13 years
