As the equation is [tex]x^2+(y-4)^2=16[/tex]

We know that the circle will have a radius of 4 and will be shifted 4 units up

The center and radius of given circle equation are (0, 4) and 6√6 units respectively.

The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.

The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²

The given circle equation is x²+(y-4)²=216.

Find the properties of the conic section

Center: (0,4)

Radius: 6√6

Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.

Domain:

[−6√6,6√6],{x∣∣−6√6≤x≤6√6}

Range: [4−6√6,4+6√6],{y∣∣4−6√6≤y≤4+6√6}

Therefore, the center and radius of given circle equation are (0, 4) and 6√6 units respectively.

f(x) = x² + 2x - 3  ..….equation1

The graph of function will be a parabola

Standard form of parabola:

y=ax²+bx+c

x-coordinate of the vertex can be found using

x = [tex]\frac{−b}{2a}[/tex]

from equation 1 find values for a, b, and c.

a = 1, b = 2, c = -3    ⇒  x=−2/2(1) ⇒  x = -1

substitute the value of x into equation 1 for y-coordinate

f(-1) = (-1)² + 2(-1) – 3 ⇒ −4

vertex =(-1,−4)

Axis of symmetry = x = -1,  

Axis of symmetry is vertical and passes through the vertex with equation

x = -1

For x-intercept, put y = 0

x² + 2x - 3=0   ⇒   x² + 3x -x - 3=0     ⇒  x( x + 3 ) -1 ( x + 3 )  ⇒ ( x − 1 )( x + 3 ) = 0

equate each factor to zero and solve for x

x − 1 = 0  ⇒  x = 1,         x + 3 = 0  ⇒  x = -3

x-intercept = { 1, -3 }

For y-intercepts put x = 0

y = (0)² + 2(x) - 3

y = -3

y-intercept = ( 0 , -3 )

The points for the vertex, x-intercepts, and y-intercept and axis of symmetry are plotted on the graph.

Carlos is 15 years old and Andre is 30 years old.

Let's represent Carlos' age as 'x', and Andre's age as 'y'.

We are given that Carlos is half as old as Andre, so we can write the equation:

x = (1/2)y

We are also told that Andre is 15 years older than Carlos, so we can write the equation:

y = x + 15

Substituting the value of y from the second equation into the first equation, we get:

x = (1/2)(x + 15)

Now, we can solve for x:

2x = x + 15

x = 15

Therefore, Carlos is 15 years old. Andre's age can be found by substituting the value of x into the second equation:

y = 15 + 15

y = 30

Answer:

a) If order matters, choices the player have = 5040

b) If order does not matter, choices the player have = 210

Step-by-step explanation:

n = 10, r = 4

When the order matters, its permutation.

permutation without repetition = P(n, r) =  [tex]\frac{n!}{(n - r)!}[/tex]

= [tex]\frac{10!}{(10 - 4)!}[/tex]

= [tex]\frac{10!}{6!}[/tex]

= 5040

When the order doesn't matter, its combination.

combination without repetition= C(n, r) = [tex]\frac{n!}{r!(n - r)!}[/tex]

= [tex]\frac{10!}{4!(10 - 4)!}[/tex]

= [tex]\frac{10!}{4! × 6!}[/tex]

= 210

If order matters, there are 5,040 different choices. If order does not matter, there are 210 different choices.

a) If order matters, the player has 10 choices for the first number, 9 choices for the second number (since it cannot be the same as the first), 8 choices for the third number, and 7 choices for the fourth number. Therefore, the total number of different choices is 10 * 9 * 8 * 7 = 5,040.

b) If order does not matter, the player is selecting a combination rather than a permutation. The number of combinations of four numbers chosen from a set of ten is given by the formula nCr = n! / (r!(n-r)!). In this case, n = 10 and r = 4, so the number of different choices is 10! / (4!(10-4)!) = 210.

Answer:x=4√6

Step-by-step explanation:

In ∆DCB, cos30°=BC/DB

BC=8√3

Applying PYTHAGORAS THEOREM in ∆BAC,

(8√3)^2=2x^2

x=4√6

Answer:

[tex]x=4\sqrt6}[/tex]

Step-by-step explanation:

Look at the picture.

ΔACD it's a triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

Therefore

CD : CB : DB = 1 : √3 : 2.

If BC = 16, then CD = 16 : 2 = 8 and CB = 8√3

ΔABC it's a triangle 45° - 45° - 90°. The sides are in ratio 1 : 1 : √2.

Therefore

AC : AB : CB = 1 : 1 : √2

If CB = 8√3, then AB = x = (8√3)/(√2)

Step-by-step explanation:

Solve using the FOIL method. The FOIL method is:

FOIL =

First

Outside

Inside

Last

, and is the order in which you do the problem.

(x + 5)(x + 6)

Follow FOIL. First, solve First (multiply x with x)

(x)(x) = x²

Next, multiply Outside (multiply x with 6)

(x)(6) = 6x

Then, multiply Inside (multiply 5 with x)

(5)(x) = 5x

Finally, multiply Last (multiply 5 with 6)

(5)(6) = 30

Combine like terms (terms with the same amount of variables, and the same variables)

x² + 6x + 5x + 30

x² + (6x + 5x) + 30

x² + 11x + 30

3                                25 + (25/4 ) = 25 + 6.25 ≈ 31

4                                31 + (31/4) = 31 + 7.75 ≈ 31+8 ≈ 39

5                                39 + (39/4) = 39 + 9.75 ≈ 39 + 10 ≈ 49

6                                 49 + (49/4) =  49+ 12.25 ≈ 49+12 ≈ 61

7                                 61 + (61/4) = 61 + 15.25 ≈ 61 + 15 ≈ 76

Answer: OPTION A.

Step-by-step explanation:

You can observe that in the figure CDEF the vertices are:

[tex]C(-2,-1),\ D(-2,0),\ E(2,2)\ and\ F(2,1)[/tex]

And in the figure C'D'E'F'  the vertices are:

[tex]C'(-8,-4),\ D'(-8,0),\ E'(8,8)\ and\ F'(8,4)[/tex]

For this case, you can divide any coordinate of any vertex of the figure C'D'E'F' by any coordinate of any vertex of the figure CDEF:

For C'(-8,-4) and C(-2,-1):

[tex]\frac{-8}{-2}=4\\\\\frac{-4}{-1}=4[/tex]

Let's choose another vertex. For E'(8,8) and E(2,2):

[tex]\frac{8}{2}=4\\\\\frac{8}{2}=4[/tex]

You can observe that the coordinates of C' are obtained by multiplying each coordinate of C by 4 and the the coordinates of E' are also obtained by multiplying each coordinate of E by 4.

Therefore, the rule that yields the dilation of the figure CDEF centered at the origin is:

The line r has equation,

To find the equation of p, we let

[tex]y = \frac{x - 4}{3} [/tex]

We now interchange x and y.

[tex]x= \frac{y - 4}{3} [/tex]

We solve for y,

[tex]3x=y - 4[/tex]

[tex]y = 3x + 4[/tex]

Therefore

[tex] {f}^{ - 1} (x) = 3x + 4[/tex]

step 1

Find the slope m

m=(-1-2)/(5+5)

m=-3/10

step 2

Find the equation of the line into slope point form

we have

m=-3/10

point A(-5,2)

y-2=(-3/10)(x+5) ----> equation of the line into slope point form

Convert to slope intercept form -----> isolate the variable y

y=-(3/10)x-(15/10)+2

y=-(3/10)x+(5/10)

simplify

y=-(3/10)x+(1/2)

ANSWER

[tex]y= log_{x}(p)[/tex]

EXPLANATION

The given expression is

[tex] {x}^{y} = p[/tex]

We take logarithm of both sides to base x.

[tex] log_{x}( {x}^{y} ) = log_{x}(p) [/tex]

Apply the power rule of logarithms to get:

[tex]ylog_{x}( {x}) = log_{x}(p)[/tex]

Logarithm of the base is 1.

This implies that,

[tex]y( 1) = log_{x}(p)[/tex]

[tex]y= log_{x}(p)[/tex]

She could've subtracted 19 from both sides of the equation in the second step to find the value of [tex]x[/tex] immediately, rather then add 19 to both sides.

[tex]34=x+19 \\ \\ 34-19=x+19-19 \\ \\ x=15[/tex]

Answer:

19  should have been subtracted from, not added to, both sides of the equation.
