Respuesta:

3x-y-1 = 0

Explicación paso a paso:

La forma estándar de ecuación de una línea se expresa como y = mx + b

M es la pendiente

b es la intersección con el eje y

Dada la coordenada P1 (2,5) y P2 (4,11)

Pendiente m = y2-y1 / x2-x1

m = 11-5 / 4-2

m = 6/2

m = 3

Sustituya m = 3 y (2,5) en y = mx + b

5 = 3 (2) + b

5 = 6 + b

b = 5-6

b = -1

Obtén la ecuación

y = 3x-1

Igualar a cero

y - 3x +1 = 0

Multiplicar por -1

3x-y-1 = 0

Esto da la ecuación requerida

The sum of 2 consecutive numbers is 69. What are the numbers?

Vaselesa [24]

Answer:

Step-by-step explanation:

z - some integer

then the consecutive integer would be:

z+1, (or z-1)

the sum is 69 so:

z + z+1 = 96

2z = 68

z = 34

z+1 = 34 + 1 = 35

(or:

z + z-1 = 69

2z = 70

z = 35

z-1 = 35 - 1 = 34)

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,360 ft Determine the flag's width and

just olya [345]

The length of rectangular mosaic flag is 710 feet and width is 470 feet

Step-by-step explanation:

Let l be the length of the flag

and

w be the width

Then according to given statement

l = w+240

Perimeter = 2360 feet

The formula for perimeter is given by:

$Perimeter = 2(Length+Width)$

Putting values

$2360 = 2[w+240+w]\\\frac{2360}{2} = \frac{2[w+240+w]}{2}\\1180 = 2w+240\\1180-240 = 2w+240-240\\940 = 2w$

Dividing both sides by 2

$\frac{2w}{2} = \frac{940}{2}\\w = 470$

The width is 470 feet

Now,

$l = w+240\\= 470+240\\=710$

Hence,

The length of rectangular mosaic flag is 710 feet and width is 470 feet

Given two central angles in any two circles, the ratio of the arc length to the radius of each corresponding circle is equal if

krok68 [10]

First, we have
s1/r1 = s2/r2

The question also states the fact that
s/2πr = θ/360°

Rearranging the second equation, we have
s/r = 2πθ/360°

Then we substitute it to the first equation
s1/r1 = 2πθ1/360°
s2/r2 = 2πθ2/360°

which is now
2πθ1/360° = 2πθ2/360°

By equating both sides, 2π and 360° will be cancelled, therefore leaving
θ1 = θ2

Suppose you waited 10 years to invest in the same retirement fund and have the same $400,000 for retirement at the same 8% inter

Ierofanga [76]

Answer:

Step-by-step explanation:

Using the compound interest formula to fins the amount after 10years;

A = P(1+r)^n

Principal P = $400,000

Rate r = 8% = 0.08

Time t = 10 years

Substitute

A = 400,000(1+0.08)^10

A = 400,000(1.08)^10

A = 400,000(2.1589)

A = 863,569.99

A ≈ 863,570

Hence the amount after 10 years is $863,570

Monthly deposit = $863,570/120 (10 years is equivalent to 120months)

Monthly deposit = 7,196.42

<em>Therefore he will have to deposit $7,196.42 into his account monthly</em>
