Step-by-step explanation:

The amount of fence the farmer will need to buy is 90 ft

The area of rectangle is the product of its length to its width.

i.e., Area of Rectangle= length x width

let the length of the back of his house be x ft.

Thus, if the second side of the garden to be 30 feet longer than the back of his house,

then the length of the second side is; (x + 30) ft.

Now,

Area = Length × width

400 = x (x + 30)

400 = x² + 30x

x² + 30x - 400 = 0

Solving the quadratic equation:

x = -40 or 10

Thus, length of second side = 10 + 30 = 40 ft

Now, Perimeter of 3 sides = 10 + 2(40)

Perimeter of 3 sides = 90 ft

The number of pennies that Anya has is equal to 15.6 pennies.

The number of dimes that Anya has is equal to 2.8 dimes.

In order to solve this word problem, we would assign variables to the number of pennies and dimes, the total number of coins, and then translate the word problem into algebraic equation as follows:

Note: 1 penny is equal to 0.05 dollar and 1 dime is equal to 0.10 dollar.

Therefore, translating the word problem into an algebraic equation, we have the following;

p = 10 + 2d                                ......equation 1.

0.05p + 0.1d = 1.06                   .......equation 2.

Substituting equation 1 into equation 2, we have:

0.05(10 + 2d) + 0.1d = 1.06  

0.5 + 0.1d + 0.1d = 1.06

0.5 + 0.2d = 1.06

0.2d = 1.06 - 0.5

0.2d = 0.56

Dimes, d = 0.56/0.2

Dimes, d = 2.8 dimes.

For the number of pennies, we have:

p = 10 + 2d

p = 10 + 2(2.8)

p = 10 + 5.6

p = 15.6 pennies.

What is a coefficient?

A coefficient is a number that does not stand alone. For example, 3w means 3 times w, and "w" is a variable, so 3 is a coefficient.

How do we find the first term?

We can find the first term by putting the numbers from greatest to least. For example, if we had the numbers: 3x+7p+2 we would rearrange the series to this: 7p+3x+2. The number that comes first in the series would be the first term.

  (a)  as x → -∞, f(x) → ∞ and as x → ∞, f(x) → ∞

Step-by-step explanation:

You want to know the end behavior of the 4th-degree function shown in the graph.

The graph has an arrow on each end of the curve shown in the figure. The left arrow points upward, indicating a tendency to +∞ as x gets more negative.

The right arrow also points upward, indicating a tendency to +∞ as x gets more positive.

  As x → -∞, f(x) → ∞ and as x → ∞, f(x) → ∞.

Answer:

16.11 (appx.)

Step-by-step explanation:

since l and m are parallel and a line intersects them, so we can say that the line is the transversal. from the figure we see that

7x + 12 = 12x - 28 [they are internal alternate angles and alternate angles are always equal to one another]

now, we can find the value of x from the equation

12x - 7x = 28 + 12

⇒ 5x = 40

⇒ x = 8

so the angle (7x+12)° is ((7*8)+12) = 68°

so (12x-28)° is also equal to 68° [cause of being alternate angles]

now, look at the figure,

angle (9y-77)° & (12x-28)° add upto a straight line as in 180°

and we know (12x-28)° = 68°

so now,

9y-77 = 68

⇒9y = 68+77

⇒9y = 145

⇒y = 16.11 (appx.)

The distance travelled by the tortoise in 1/4 hour is 0.5miles

A rate is a more general measure in which one quantity is divided by another quantity, where both quantities don't necessarily need to have the same unit of measure. For example , Tayo typed 500 words in 50 minutes. This means that the rate of Tayo in typing is 500/50= 10words per minutes.

The tortoise travels 2miles in 1hour. There are two terms of different unit, which are distance in miles and time in hours

if the tortoise travels 2miles in 1hour

The standard form of the equation of the circle is (x-5)² + (y+3)² = 9² and the general form is x² + y² + 10x + 6y - 47 = 0 .

We know that the general form of the equation of a circle is given by the following equation:

(x-h)² + (y-k)² = r² . Where r is the radius of the circle and (h, k) is the center of the circle.  

So the general equation of the circle is (x-5)² + (y+3)² = 9² .

Let's first define a circle in order to determine its equation. A circle is formed by every point in a plane that is uniformly spaced from another point.

The constant point is located at the center of the circle. The radius of a circle is the separation between its center and any point along its circumference.

(x-5)² + (y+3)² = 9²

or, x² + 10x + 25 + y² + 6y + 9 = 81

or, x² + y² + 10x + 6y - 47 = 0

Hence the general form of the circle is x² + y² + 10x + 6y - 47 = 0.

By evaluating a linear equation, we can see that 677.25 mL will be infused in 5.25 hours.

We know that the solution is being infused at a rate of 2.15 mL per minute.

So, t minutes after the infusion starts, the volume infused is given by the linear equation:

V(t) = 2.15mL*t

Here we want to see how many mL would infuse in 5.25 hours, to do that, we need to write that time in hours:

We know that one hour = 60 min, then:

5.25 h = 5.25*60 min = 315 min

Then the volume infused is:

Answer: B

Step-by-step explanation:

The required amount of 25% saline solution is 8 liters.

In mathematics, the equation that used to find an Unknow quantity is known as Linear Equation. Here we use different types of variables to represent the unknown value like x, y, z or a, b, c.. etc.

Here we have

4 liters of a 40% saline  

we need to make it a 30% of saline solution by adding a mount of 25% saline solution

Let us assume that we added x L of 25% of saline solution  

After adding x L of 25% saline into 4 liters of 40% saline to get 30% saline solution then the resultant solution is “x+4” liters of 30% saline.

The mathematical representation for the above line will be

⇒ x litres 25% saline + 4 litres 40% saline = (x+4) litres 30% saline

⇒ x(25%) + 4(40%) = (x+4)(30%)

⇒ 25x/100 + 4(40/100) = (x+ 4)30/100  

⇒ 25x + 160 = (x +4)30  

⇒ 25x + 160 = 30x + 120

⇒ 30x - 25x = 160 - 120

⇒  5x = 40

⇒ x = 8

Therefore

The required amount of 25% saline solution is 8 liters

Let # of 3.50 shares be "x" ; value is 3.5x dollars

# of 6.00 shares is "500-x" ; value is 6(500-x)=3000-6x dollars

value = value = 2187.50

3.5x + 3000-6x = 2187.5

The value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x and the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.

First, let us know some laws of exponent:

We are given;

[tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] and [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex].

Now, we will solve one by one;

[tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex]

[tex]= \sqrt[5]{\frac{2^{10}(x^{-10})}{(2^5x^{-15})}}[/tex]

[tex]=[({2^{10}. 2^{-5}) (x^{-10}.x^{15})}]^\frac{1}{5}[/tex]

[tex]=[({2^{10-5}) (x^{-10+15})]^\frac{1}{5}[/tex]

[tex]=[({2^{5}) (x^{5})]^\frac{1}{5}[/tex]

= 2x

So, the value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x.

Now,

[tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex]

[tex]=\frac{(2^3x^6y^{-3})^\frac{1}{3} }{(2^3x^3y^3)}[/tex]

[tex]=\frac{(2x^26y^{-1})}{(2^3x^3y^3)}[/tex]

[tex]=\frac{1}{(2^{3-1}x^{3-2}y^{3+1})}[/tex]

[tex]=\frac{1}{(2^{2}x^{1}y^{4})}[/tex]

= 1 / 4xy^4

So, the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.

Thus, the value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x and the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.

Using dilation rules, the dilated triangle whose coordinates of the vertices are as follows: A'(-2 , 2), B'(-1,0), C'(1 , 2).

What is the rule for a dilation?

To dilate a figure by a factor of a, each coordinate of each vertex of the image is multiplied by a, that is, the following rule is applied:

(x, y) -> (ax, ay).

suppose the coordinates of the vertices of ABC are given as follows:

A(-6,6), B(-3,0), C(3,6).

After a dilation with a scale factor of 1/3, the coordinates of the vertices of A'B'C' will be given as follows:

A'(-2 , 2), B'(-1,0), C'(1 , 2).

These coordinates are derived multiplying the coordinates of A, B and C by 1/3.

For the image of triangle DEF, each of the coordinates of D, E and F will be multiplied by 2 to generate the dilated triangle.
