Answer:

Below in bold.

Step-by-step explanation:

x^2 + y^2 - 8x + 12y + 40 = 0

x^2 - 8x + y^2 + 12y = -40

Complete the square on the x and y terms:-

(x - 4)^2 - 16 + ( y + 6)^2 - 36 = -40

(x - 4)^2 + (y + 6)^2 = -40 + 16 + 36

(x - 4)^2 + (y + 6)^2 = 12

So the centre is at (4, -6) and the radius is √12.

Answer:

The circle is centered at (4,-6) and has a radius of √12.

Step-by-step explanation:

The standard form for the circle equation is:

[tex](x-a)^2+(y-b)^2=r^2[/tex]

You have:

[tex]x^2+y^2-8x+12y+40=0[/tex]

First complete the square for the 'x' terms:

[tex](x^2-8x+40)+y^2+12y=0[/tex]

[tex](x^2-8x+16-16+40)+y^2+12y=0[/tex]

[tex](x^2-8x+16)+y^2+12y+24=0[/tex]

[tex](x-4)^2+y^2+12y+24=0[/tex]

The 'x' terms are now in standard form. Work on the 'y' terms by completing the square once again:

[tex](x-4)^2+(y^2+12y+36-36+24)=0[/tex]

[tex](x-4)^2+(y^2+12y+36)-12=0[/tex]

[tex](x-4)^2+(y+6)^2-12=0[/tex]

Add the 12 to the other side:

[tex](x-4)^2+(y+6)^2=12[/tex]

The circle is centered at x = 4, y = -6, and has a radius of √12.

Answer:

4 weeks

Step-by-step explanation:

Given information:

Given equation:

[tex]\sf b = 85 + w(10 + 8)[/tex]

(where b is the balance and w is the number of weeks)

To find the number of it will take to have a balance of $150, substitute b = $150 into the given equation and solve for w:

[tex]\implies \sf 85+w(10+8)=150[/tex]

[tex]\implies \sf 85+18w=150[/tex]

[tex]\implies \sf 85+18w-85=150-85[/tex]

[tex]\implies \sf 18w=65[/tex]

[tex]\implies \sf \dfrac{18w}{18}=\dfrac{65}{8}[/tex]

[tex]\implies \sf w=3.6111...[/tex]

[tex]\implies \sf w=4\:weeks[/tex]

Therefore, there will be $150 in the bank account 4 weeks from now.

Answer: 2/sqrt6

Step-by-step explanation:

tan theta=perpendicular/base so

cot theta =base /perependicular=sqrt2/2

while sin theta=perpendicular/hypotenous=2/x

here x is unkown to find it we will use pythagoras theorem

(hypoteneous)^2=(Base)^2+(perependicular)^2

                            =(sqrt 2)^2+(2)^2

                            =2+4

  (hypoteneous)^2=6

  hypotenous   =sqrt6

so

sin theta=2/sqrt6

The equation of the line passing through the points (−4,−7) and (−4,−6) in the form of a will be a + 4 = 0.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

The equation of the line passing through the points (−4,−7) and (−4,−6) will be

y + 6 = [(−6 + 7) / (−4 + 4)] (x + 4)

y + 6 = (1/0)(x + 4)

x + 4 = 0

Put x = a, then the equation will be

x + 4 = 0

a + 4 = 0

The product and the sum of the functions will be 3x² - 6x - 24 and 4x + 2. The value of the function (f - g) at x = 4 is negative 18.

In mathematics, functions are everywhere and are necessary for constructing physical connections. A function is a statement, rule, or law that establishes the connection between two variables.

The functions are given below.

f(x) = x - 4

g(x) = 3x + 6

Then the product of the functions will be

(f × g)(x) = (x - 4)(3x + 6)

(f × g)(x) = 3x² -12x + 6x - 24

(f × g)(x) = 3x² - 6x - 24

Then the sum of the functions will be

(f + g)(x) = x - 4 + 3x + 6

(f + g)(x) = 4x + 2

Then the difference in the functions at x = 4 will be

(f - g)(4) = (x - 4) - (3x + 6)

(f - g)(4) = x - 4 - 3x - 6

(f - g)(4) = -2x - 10

(f - g)(4) = -2 (4) - 10

(f - g)(4) = -8 -10

(f - g)(4) = -18

The area of the training field to the nearest whole number is 8719 msq. meter

The given field is made up of a rectangle and 2 semi circles. The formula for calculating the area of the field is:

Area of the field = area of circle + area of rectangle

Area of field = 3.14(32)² + (86)(64)
Area of field = 3215.36 + 5504

Area of the field = 8719 msq. meter

Hence the area of the training field to the nearest whole number is 8719 msq. meter

Answer:

The answer is choice c. This is because texts present the same facts in fiction or nonfiction life.

Two polygonal regions are similar with scale factor 7, if the area of the smaller region is 490 cm² then the area of the larger region would be 3430 cm²

An equation is an expression that shows the relationship between two or more numbers and variables.

Dilation is the increase or decrease in the size of a figure by a scale factor.

Two polygonal regions are similar with scale factor 7. The area of the smaller region is 490 cm², hence:

Area of larger region = 7 * 490 cm² = 3430 cm²

Two polygonal regions are similar with scale factor 7, if the area of the smaller region is 490 cm² then the area of the larger region would be 3430 cm²

Step-by-step explanation:

remember, a probability is always desired cases over possible cases.

and the combination of the probabilities of two (or more) events means to multiply these probabilities.

the probability to get a specific number on the spinner is 1/4 (1 desired number over 4 possible numbers).

so, to get first a number less than 3 ... - that means, the only desired outcome is the number 2.

so,
