Answer:

Shorter sides: 270 feet.

Larger side: 540 feet.

Greatest possible area: 145800 square feet.

Step-by-step explanation:

So we need fencing around the garden except along the river.

The opposite sides of a rectangular are congruent.

So the sides perpendicular to the river in the picture are both of the same length, let's call it x.  The length opposite the river is y.  

So the perimeter excluding the side along the river is

x+x+y or 2x+y or 1080 is how much fencing we want.

So we have the equation:

2x+y=1080

The area of rectangle can be found by multiplying it's dimensions:

xy=A

We want to find the dimensions that provide us with the maximum area.

This is our area function so for:

A=xy

We need the area to be in terms of one variable.

Let's use our condition that 2x+y=1080.

2x+y=1080

Subtract 2x on both sides:

y=1080-2x

or

y=-2x+1080

We are going to plug this into:

[tex]A=xy[/tex]

[tex]A=x(-2x+1080)[/tex]   :  I replaced y with -2x+1080 since y=-2x+1080.

[tex]A=-2x^2+1080x[/tex] :  I distribute.

Let's find the x-coordinate of the vertex.

To do this we need to determine [tex]a[/tex] and [tex]b[/tex] in the comparison of

[tex]A=ax^2+bx+c[/tex].

[tex]a=-2[/tex]

[tex]b=1080[/tex]

[tex]c=0[/tex]

The formula for the x-coordinate of the vertex is [tex]\frac{-b}{2a}[/tex].

[tex]\frac{-b}{2a}=\frac{-1080}{2(-2)}=\frac{1080}{4}=270[/tex]

We could plug this into our area Area function in terms of to find maximum area.

We could also wait til later.  I think I will do both for a later check.

[tex]A=-2x^2+1080x[/tex] with [tex]x=270[/tex]

[tex]A=-2(270)^2+1080(270)[/tex]

[tex]A=145800[/tex]

So we one dimension of the rectangle so for which is 270 feet.

We have the maximum area which is 145800 square feet.

Now recall y=-2x+1080.

y=-2x+1080 with x=270

y=-2(270)+1080

y=540

So we have one dimension of the rectangle is 270 feet.

Another dimension is 540 feet.

And the area of the rectangle is 145800 square feet.

Does 270(540) equal 145800? 270(540)=145800 so yes.

Let's check to see if we have 1080 feet of fencing.

So we have 2 small sides of 270 and 270 feet.

We have a larger side which is 540 feet.

270+270+540=10180 so everything checks out.

I'm going to assume that you meant to write: The square of a number exceeds that number by 12. What are the two possible solutions.

In other words x² = x + 12

4² is 16.

4 + 12 = 16

(-3)² is 9

-3 + 12 = 9

Hope this helped!

Answer:

two real roots

Step-by-step explanation:

x^2 + 7x – 6 = 0

We can use the discriminant

This is in the form ax^2 +bx+c=0

b^2 -4ac

If  b^2 -4ac> 0 there are 2 real roots

If b^2 -4ac = 0 there is one real root

If b^2 -4ac <0 there are two complex roots

7^2 -4(1)*(-6)

49 +24

73

Since 73 > 0 there are two real roots

Answer:

The graph of the equation intersects the x-axis at two points. Therefore, it has two solutions.

Step-by-step explanation:

Answer:

I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.

For example, if you have the following inequation:

x-2> 1

x>3

Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U  (3, inf) instead of 'x>3 or x<-3' which is more confusing.

Answer:

60(1/5)^(n-1).

Step-by-step explanation:

The common ratio  r   is 12/60 = 12/5 / 12  = 12/25 / 12/5 = 1/5.

The first term a1 = 60 so the explicit rule is

a1 * r^(n-1)

= 60(1/5)^(n-1).

aₙ=60(1/5)ⁿ⁻¹ is the explicit rule for the geometric sequence 60,12,12/5, 12/25,12/125,... .This can be obtained by using the formula of geometric sequence.

Sequence is s collection of objects in a particular order and repetitions are allowed.

Geometric Sequence:

In the given question, first term a=60

Common ratio r = a₂/a₁ = 12/60 = 1/5 ⇒ r = 1/5

By definition, arⁿ⁻¹ = (60)(1/5)ⁿ⁻¹ is the required explicit rule for the geometric sequence.

Hence aₙ=60(1/5)ⁿ⁻¹ is the explicit rule for the geometric sequence 60,12,12/5, 12/25,12/125,... .

Answer:

x+5

Step-by-step explanation:

Given:

Dividend= x4 + 5x3 – 3x – 15

Quotient=(x3-3)

As per the rule of division of polynomial:

Dividend = Divisor × Quotient + Remainder

Divisor= required polynomial p(x)

remainder=0

x4 + 5x3 – 3x – 15= p(x) *(x3-3) + 0

p(x)=x4 + 5x3 – 3x – 15/x3-3

By long division we get

p(x)= x+5 !

Answer:

The polynomial is x+5.

Step-by-step explanation:

Here we need to recall the algorithm of the division for polynomials, which is very similar to the one for integers. Given polynomials P(x) and Q(x), there always exist polynomials S(x) and R(x) such that

P(x) = Q(x)S(x) + R(x)

where

In this particular case,  

Then, x⁴+5x³-3x-15 = (x³-3)Q(x). In order to find Q(x) we must complete the division x⁴+5x³-3x-15/x³-3. This gives us that Q(x)=x+5.

Answer:

Prasant needs more than 4.5 bags of candy to hand out during Halloween.

Step-by-step explanation:

The correct method to write a statement that matches the inequality [tex]\( h > 4.5 \)[/tex] is to express that the value of [tex]\( h \)[/tex] is greater than 4.5. This can be done by stating that [tex]\( h \)[/tex] must be some quantity more than 4.5, without specifying the exact amount by which [tex]\( h \)[/tex]exceeds 4.5.

For example, one could write the statement as:

The value of [tex]\( h \)[/tex] is more than 4.5 units.

This statement correctly conveys that [tex]\( h \)[/tex] is not equal to 4.5 and is somewhere on the number line to the right of 4.5, with no upper limit specified. It is important to note that the inequality [tex]\( h > 4.5 \)[/tex] does not include the value 4.5 itself; [tex]\( h \)[/tex] must be strictly greater than 4.5.

In summary, the statement should indicate that \( h \) is any number that is greater than 4.5, and the value of [tex]\( h \)[/tex] can be infinitely close to 4.5 but never equal to or less than it.

The image is blurred.

The given frequency is showing only 4 intervals, that means there should be only 4 bars in the right histogram, that lead us only to the first or second choice as right answers.

Now, according to the frequency table the first interval is larger than the second interval and the third interval is larger than the fourth interval. This means the first bar must be taller than the second bar, and the third bar must be taller than the fourth bar, and the second histogram is showing this.

Therefore, the right histogram is the second one.

Answer:

Advantage: If a car is losing value at a constant rate, then the linear function represents accurately the depreciation of the car.

Disadvantage: If the car is not losing value at a constante rate, then when we calculate the value of the car 'x' years after it was sold, we won't get  an accurate result.

If the minivan is purchased for $29,248 and the first year it depreciates $3000. Then, the linear function that represents the value of the car is:

y = $29,248 - $3000x

Where 'y' represents the value of the car, and 'x' represents the number of years.

Let us explain this with an example. After 6 years, the price will be:

y = $29,248 - $3000(6) =  $11,248

The advantages of using a linear function to represent the depreciation of a car are simplicity and ease of calculation, but it assumes constant depreciation rate. On the other hand, an exponential function can account for varying depreciation rates, but can be more complex. The linear function to represent the value of the minivan after x years is V(x) = 29,248 - 3,000x.

When representing the depreciation of a car over time, using a linear function has advantages and disadvantages. The advantages are that it provides a simple and straightforward representation of the depreciation, and it is easy to calculate and understand. However, a linear function assumes that the car depreciates at a constant rate over time, which may not always be accurate.

On the other hand, using an exponential function to represent the depreciation of the car has advantages and disadvantages as well. The advantage is that it can account for different rates of depreciation over time, which may be more realistic. However, exponential functions can be more complex to calculate and understand.

In the case of the minivan that depreciates $3,000 in the first year, a linear function can be used to represent the value of the car x years after it was sold. The linear function would be V(x) = 29,248 - 3,000x, where V(x) is the value of the car x years after it was sold.

Answer: Multiply (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x2 + 11x + 120

We know that David wants to increase the price per cup to increase his revenue. He found out that for every $0.25 grows( increase), x, in the price for each cup.

In the event of a price increase, 2 cups remain unsold, and doubling the cups is still not sold. Then the numbers are sold (60-2x). Depending on the choice:

Revenue= (60 -2x)(2 +0.25x)

60·2 +60·0.25x -2x·2 -2x·0.25x

= -0.5x² +11x +120

Answer:

Multiply (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x2 + 11x + 120

Step-by-step explanation:

Here, x represents the times at which the price is increased,

Since, the original price of one cup = $ 2,

So, after increasing x times of $ 0.25, the new price of each cup = 2 + 0.25x,

Also, the original number of mochas = 60,

Given,

With increasing the price $ 0.25, x times, the number of cup is decreased by 2 times of x,

That is, the new number of mochas = 60 - 2x

Hence, the total revenue would be,

y = new price of each cup × new number of mochas

⇒ y = (2 + 0.25x)(60 - 2x)

⇒ y = 120 - 4x + 15x - 0.5x²

⇒ y = -0.5x² + 11x + 120

He can find find the equation which represents his daily revenue, by Multiplying (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x² + 11x + 120
