how to simplify 4x5 / 1+9

Answer:

Length = 60 inches

Width = 17 inches

Step-by-step explanation:

Let width = w

Length = 3w + 9

Perimeter = 154

Perimeter = 2(length + width)

2(3w + 9 + w) = 154

8w + 18 = 154

8w = 154 - 18

8w = 136

w = 136/8

w = 17 inches

Length = 3w + 9 = 3(17) + 9 = 60 inches

The dimensions of the rectangle are 43inches and 20inches if the perimeter of the rectangle is 126 inches.

Leth the width of the revtangle be x.

According to the given question.

The perimeter of the rectangle is 126 inches.

The length of the rectangle is three more than double the width.

⇒ Length of the rectangle  = 3 + 2x

Now, according to the given conditions we can say that

Perimeter of the rectangle = 2( length + width)

⇒ 126 = 2(3 + 2x + x)

⇒ 126  = 2(3 + 3x)

⇒ 63  = 3 + 3x

⇒ 63 - 3 = 3x

⇒ 60 = 3x

⇒ x = 20 inches

Therefore, the length of the rectangle = 3 + 2(20) = 3 + 40 = 43

Hence, the dimensions of the rectangle are 43inches and 20inches if the perimeter of the rectangle is 126 inches.

5x-2y = -2 is the equation of line that passes through the point (-2,-4) and is parallel to the line 5x-2y=6.

Given that, (x₁, y₁) = (-2, -4) and parallel to 5x - 2y = 6

Let's calculate the slope of 5x - 2y = 6

Rewrite the equation in y = mx + c form

5x - 2y = 6

⇒ -2y = 6 - 5x

⇒ -y = 3 - 5/2x

⇒ y = -3 + 5/2x

⇒ y = 5/2x - 3

Thus, the slope (m) = 5/2

As the line is parallel to 5x - 2y = 6 it will have a slope of 5/2.

The point-slope formula states (y - y₁) = m(x - x₁)

Now, substituting the value of m = 5/2 and (x₁, y₁) = (-2, -4), we get

(y - y₁) = m(x - x₁)

⇒ (y - (-4)) = 5/2(x - (-2))

⇒ (y+4) = 5/2(x+2)

⇒ 2(y+4) = 5(x+2)

⇒ 2y+8 = 5x+10

⇒ 5x-2y+10-8 = 0

⇒ 5x-2y+2 = 0

⇒ 5x-2y = -2

Hence, the line that passes through the point (-2,-4) and is parallel to the line 5x-2y=6 is 5x-2y = -2.

Therefore, 5x-2y = -2 is the required answer.

Step-by-step explanation:

this is similar to the complete approach to find the midpoint. just instead of 1/2 we are looking for 3/10 of the distance.

the general approach is

A + (B - A)×factor

factor can be 1/2 or 3/10 or 7/10 or 24/29 or ...

so, we have

(-3, -6) + ((9 - -3)×3/10, (5 - -6)×3/10) =

= (-3, -6) + (12×3/10, 11×3/10) =

= (-3, -6) + (3.6, 3.3) = (0.6, -2.7)

the point 3/10 of the way from A to B is

(0.6, -2.7)

Expanding out the equation, we get

[tex]x^2 - ax - bx+ab+x^2 -bx-cx+bc+x^2 -ax-cx+ac=0 \\ \\ 3x^2 -x(2a+2b+2c)+(ab+bc+ac)=0[/tex]

Considering the discriminant,

[tex](2a+2b+2c)^2 - 4(3)(ab+bc+ac) \\ \\ =4a^2 + 4b^2 + 4c^2 + 8(ab+bc+ac)-12(ab+bc+ac) \\ \\ =4(a^2 + b^2 + c^2 - ab - bc - ac) \\ \\ =2((a-b)^2 + (b-c)^2 + (c-a)^2)[/tex]

This is always non-negative, meaning the roots are real.

The roots are equal if and only if the discriminant is 0, which is when a=b=c.

Answer:

[tex](x + 4)^{2}[/tex] = 36

Step-by-step explanation:

So the "sum of a number and 4" is what gets squared and that together is equal to 36.

The limit dimensions of the part are 3.135 inches and 3.155 inches

The given parameters are

Thickness = 3.145 inches

Tolerance = 0.010 inches

The limit dimensions of the part are calculated as

Limit = Thickness +/- Tolerance

So, we have

Limit = 3.145 inches +/- 0.010 inches

Expand the above expression

So, we have

Limit = (3.145 inches - 0.010 inches, 3.145 inches + 0.010 inches)

Evaluate the sum

Limit = (3.135 inches, 3.155 inches)

Hence, the limit dimensions of the part are 3.135 inches and 3.155 inches

The absolute change in the town's population from 2008 to 2010 is 1,050 and the percentage change is 32.3%.

Here, we are given that the population of a town increased from 3,250 in 2008 to 4,300 in 2010.

The absolute change can be calculate as-

Final population count - initial population count

= 4,300 - 3,250

= 1,050

Thus, absolute increase = 1,050

Now, the percentage increase can be calculated as follows-

percentage change = absolute change in population/ initial population count × 100

= 1,050/ 3,250 × 100

= 10500/ 325

= 32.3%

Thus, the absolute change in the town's population from 2008 to 2010 is 1,050 and the percentage change is 32.3%.

Step-by-step explanation:

The value of f(5) is 4375.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given:

f(1)= 7,

f(n) = 5f(n-1)

f(2) = 5f(1)

     =5*7

f(2)= 35

f(3) =  5f(3-1)

f(3) =  5f(2)

f(3) =  5*35

f(3) = 175

f(4) =  5f(4-1)

f(4) =  5f(3)

f(4) =  5*175

f(4) = 875

f(5) =  5f(5-1)

f(5) =  5f(4)

f(5) =  5*875

The volume of the two cylinders is 2424. The area of the cross-section will be equal if another cross-section is obtained at a different height.

The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it.

The formula for the volume of a cylinder is given as:

V=π r² h

Now from the figure,

We have, for the first cylinder the height is 16 units and the radius is 7 units.

Hence,

V = 22/7 × 7² × 16

V = 22/7 × 7 × 7 × 16

V = 2424

Answer:

  x2 = 7/6

Step-by-step explanation:

You want the second approximation using Newton's method, given that the first approximation is x1=1 and the function tangent at x=1 is y=7-6x.

Newton's method approximates the function by its tangent line at the point (x, f(x)). That is, the second approximation is the x-intercept of the tangent line y = 7 -6x. That value of x is ...

  0 = 7 -6x

  6x = 7 . . . . . add 6x

  x = 7/6 . . . . divide by 6

The second approximation is x2 = 7/6.

f(t) = 80,00[tex](1+ 0.056)^{t}[/tex] is the exponential function that represents the model. The number of visits increase by 0.015% daily.

Here, we are given that a blogger found that the number of visits to her Web site increases 5.6% annually.

The exponential function is given as-

Final value = initial value [tex](1 + r)^{t}[/tex]

where r = rate of change

and t = time

here, r = 5.6%

r = 0.056

Further, the Web site had 80,000 visits this year ⇒ initial value = 80,000

Thus, we can get the following function-

f(t) = 80,00[tex](1+ 0.056)^{t}[/tex]

where f(t) represents the views after t years.

Now, since we are given that the views increase by 5.6% in 1 year

and 1 year = 365 days

⇒ daily rate = 5.6/365

= 0.015

Thus, the number of visits increase by 0.015% daily.
