Write the equation of a circle with the center at (-1, -4) that through the point (-1,-1) ​

Answer:

y=5/6x -12

Step-by-step explanation:

first find the slope of the graph

by using 2 points (0,-4) (12,6)

[tex]m = \frac{6 - ( - 4)}{12 - 0} = \frac{10}{12} = \frac{5}{6} [/tex]

and bcoz they r parallel they have the same slope,,now find the equation by using the given point

y-y=m(x-x)

y+2=5/6(x-12)

[tex]y = \frac{5}{6} x - 12[/tex]

Answer:

a) El procedimiento queda resumido en lo que sigue:

1) Se halla el área de la base del cuadrilátero.

2) Se multiplica el resultado anterior por la longitud del prisma.

b) La expresión para calcular el volumen del prisma ([tex]V[/tex]), en unidades cúbicas, es:

[tex]V = w\cdot h \cdot l[/tex]

Donde:

[tex]w[/tex] - Ancho de la base, en unidades.

[tex]h[/tex] - Altura de la base, en unidades.

[tex]l[/tex] - Longitud del prisma, en unidades.

Step-by-step explanation:

a) Dimensionalmente hablando, la unidad de volumen es igual al cubo de la unidad de longitud. Se explica a continuación los pasos necesarios para el cálculo de prisma cuadrangular:

1) Se halla el área de la base del cuadrilátero.

2) Se multiplica el resultado anterior por la longitud del prisma.

b) En consecuencia, se deriva la expresión para el volumen del prisma:

[tex]V = A\cdot l[/tex] (1)

Donde:

[tex]A[/tex] - Área de la base del prisma, en unidades cuadradas.

[tex]l[/tex] - Longitud del prisma, en unidades.

[tex]V = w\cdot h \cdot l[/tex] (2)

Donde:

[tex]w[/tex] - Ancho de la base, en unidades.

[tex]h[/tex] - Altura de la base, en unidades.

Answer:

x  =  2  cm

y  = 2  cm

A(max) =  4 cm²

Step-by-step explanation: See Annex

The right isosceles triangle has two 45° angles and the right angle.

tan 45°  =  1  =  x / 4 - y        or     x  =  4  -  y     y  =  4  -  x

A(r)  =  x* y

Area of the rectangle as a function of x

A(x)  =  x  *  (  4  -  x )       A(x)  =  4*x  -  x²

Tacking derivatives on both sides of the equation:

A´(x)  =  4 - 2*x             A´(x)  =  0            4   -  2*x  =  0

2*x  =  4

x  =  2  cm

And  y  =  4  - 2  =  2  cm

The rectangle of maximum area result to be a square of side 2 cm

A(max)  = 2*2  =  4 cm²

To find out if A(x) has a maximum in the point  x  =  2

We get the second derivative

A´´(x)  =  -2           A´´(x)  <  0   then A(x) has a maximum at  x = 2

The maximum area of the rectangle inscribe in the right isosceles triangle

is [tex]\rm \bold{4\;cm^2}[/tex]

Given that a rectangle is to be inscribed in an isosceles triangle

As per the attached figure we can write the following

Let ΔABC  represents the isosceles triangle from the given data in the question we can write the following observations

Length of AB = 4

Length of BC = 4

∠ACB = 45°

∠BAC = 45°

Length of AC = [tex]\rm 4\sqrt2[/tex]

We have to consider a rectangle within the isosceles triangle such that  

area of rectangle is maximum

The area of rectangle is given by equation (1)

[tex]\rm Area \; of \; rectangle = Length \times Breadth ........(1) \\[/tex]

Let the area of rectangle inscribed by the isosceles triangle is " A"

Let the lenght of the rectangle be "x "

Let the width of the rectangle be " y "

So according to equation (1) the area of rectangle inscribed into the triangle is given by

[tex]\rm A = x \times y.......(2)[/tex]

In ΔAED we can write

[tex]\int\limits^a_b {x} \, dx \rm tan 45= \dfrac{Perpendicular}{Base } = \dfrac{4-y}{x} \\1 = \dfrac{4-y}{x} \\ x = 4-y .......(3) \\[/tex]

From equation (2) and (3) we get

[tex]\rm A = (4-y)(y) \\A = 4y -y^2......(4)[/tex]

On differentiating the given function with respect to y we get

[tex]\rm A' = 4- 2y \\[/tex]

On putting A' =0 we get

[tex]\rm 4-2y =0 \\2y = 4\\y = 2[/tex]

A'' is negative hence it is the maximum value of y

So we can conclude that the maximum value of y is 2

So from equation (4) the maximum area is [tex]\rm 2\times 2 = 4\; cm^2[/tex]

The maximum area of the rectangle inscribe in the right isosceles triangle

is [tex]\rm \bold{4\;cm^2}[/tex]

Given:

In triangle PQR, QS⊥PR, QS=x, PR=90 and RS=18.

To find:

The value of x.

Solution:

According to right triangle altitude theorem (geometric mean theorem), if an altitude of a right triangle divides the base into two segments then the square of altitude is equal to the product segments of the base.

Using right triangle altitude theorem, we get

[tex]\dfrac{QS}{PS}=\dfrac{RS}{QS}[/tex]

[tex]QS^2=RS\times PS[/tex]

[tex]x^2=18\times (90-18)[/tex]

[tex]x^2=18\times 72[/tex]

[tex]x^2=1296[/tex]

Taking square root on both sides, we get

[tex]x=\sqrt{1296}[/tex]

[tex]x=36[/tex]

Therefore, the correct option is B.

Answer:

-2?

Step-by-step explanation:

use y2-y1 over x2-x1 to find the answer. So you would do -2--5/3 over 4--2. The two negitives turn into a positive. SO it is now -2+5/3 over 4+2. -2+5/3= -1/3 over 4+2=6 it is now -1/3/6 which equals -2. So I think the answer is -2. I do not know if you should trust me on this but I tried.

Answer:

  A.  $26,346

Step-by-step explanation:

The cost is the sum of all of the payments made:

  cost = down payment +24×monthly payment +deposit +acquisition fee +after-lease price

  cost = $1500 +24×279 +350 +700 +17100 = $26,346

The total price of the car if you buy it after leasing is $26,346.

If you're looking for the cube roots of √(3 + i ), you first have to decide what you mean by the square root √(…), since 3 + i is complex and therefore √(3 + i ) is multi-valued. There are 2 choices, but I'll stick with 1 of them.

First write 3 + i in polar form:

3 + i = √(3² + 1²) exp(i arctan(1/3)) = √10 exp(i arctan(1/3))

Then the 2 possible square roots are

• √(3 + i ) = ∜10 exp(i arctan(1/3)/2)

• √(3 + i ) = ∜10 exp(i (arctan(1/3)/2 + π))

and I'll take the one with the smaller argument,

√(3 + i ) = ∜10 exp(i arctan(1/3)/2)

Then the 3 cube roots of √(3 + i ) are

• ∛(√(3 + i )) = ¹²√10 exp(i arctan(1/3)/6)

• ∛(√(3 + i )) = ¹²√10 exp(i (arctan(1/3)/6 + π/3))

• ∛(√(3 + i )) = ¹²√10 exp(i (arctan(1/3)/6 + 2π/3))

On the off-chance you meant to ask about the cube roots of 3 + i, and not √(3 + i ), then these would be

• ∛(3 + i ) = ⁶√10 exp(i arctan(1/3)/3)

• ∛(3 + i ) = ⁶√10 exp(i (arctan(1/3)/3 + 2π/3))

• ∛(3 + i ) = ⁶√10 exp(i (arctan(1/3)/6 + 4π/3))
