No, the gardener does not have enough fencing for the area of the garden to be 1300 square feet. The maximum possible area that can be achieved with 140 feet of fencing is given by the function A(w) = 70w - w^2. We need to find the width value (w) that corresponds to an area of 1300 square feet.

To determine if the gardener has enough fencing, we can set up an equation using the given function: 1300 = 70w - w^2. Rearranging this equation, we get w^2 - 70w + 1300 = 0.

By solving this quadratic equation, we find that the roots are w = 25 and w = 45. Since the width value (w) must be positive, we can conclude that the width of the garden cannot be 45 feet. Therefore, the gardener does not have enough fencing to create a garden with an area of 1300 square feet.

In summary, based on the given quadratic equation, the gardener cannot achieve an area of 1300 square feet with the available 140 feet of fencing. The maximum achievable area corresponds to a width of 25 feet.

Answer:

The answer is option 3.

Step-by-step explanation:

In a linear equation, y = mx + b where m represents gradient and b is the y-intercept (line touches y-axis).

In this graph, the gradient is positive and the y-intercept is -3.

So the possible function for this is f(x) = x - 3 .

The polar coordinates for x² + y² - 4x = 0 are (4 cos θ, θ) where θ is the angle made by the position vector with the positive x-axis in anti-clockwise direction.

We need to write the equation using polar coordinates (r,θ).To express the rectangular coordinates in polar form, we must recall some basic relations:

r = √(x² + y²)And tanθ = y/x

Therefore, tanθ = y/x implies x = r cos θ and y = r sin θ.

Substituting these values into the given equation we get,x² + y² - 4x = 0⇒ (r cos θ)² + (r sin θ)² - 4(r cos θ) = 0⇒ r² (cos²θ + sin²θ) - 4r cos θ = 0⇒ r² - 4r cos θ = 0

Dividing both sides by r, we get, r - 4 cos θ = 0⇒ r = 4 cos θ

Answer:

10-3*(6+5)-4=63

Step-by-step explanation:

I used a calculator until I got the answer.

The correct parentheses to put in equation is 100-3(6+5)-4 = 63

A parenthesis or parenthetical phrase is an explanatory or qualifying word, clause, or sentence inserted into a passage.

Given that, expression, 100 - 3 x 6 + 5 - 4= 63

To make equation true, just put parentheses around (5+6)

That will give,

100-3(6+5)-4

= 100 - 33 - 4

= 100 - 37

= 63

The error in writing the rule for the nth term of the geometric sequence is in the step where the value of a₁ is determined. The correct value for a₁ is √(147/49) or √3, not √√21.

In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio (r). The general formula for the nth term (aₙ) of a geometric sequence is given by aₙ = a₁ * r^(n-1), where a₁ is the first term and r is the common ratio.
Given that a₃ = 147 and r = 7, we can find the value of a₁ by substituting these values into the formula. Let's correct the error in the calculation step:
a₃ = a₁ * r^(3-1)
147 = a₁ * 7²
147 = a₁ * 49
To isolate a₁, we divide both sides of the equation by 49:
a₁ = 147 / 49
a₁ = 3
Therefore, the correct value for a₁ in the geometric sequence is 3, not √√21 as stated in the error.

When you ask for evaluation of a math expression, you need to write what you mean.

Here, the order of operations requires you compute the exponentials before you do the division or addition:

Answer:

284/3 πx³

Step-by-step explanation:

Volume of a cylinder is expressed as shown:

V = πr²h

r is the radius of the cylinder

r = diameter/2

r = 8x/2

r = 4x

Height of the cylinder = 6x

Volume of the roll with out the hole

V = π(4x)²(6x)

V = 16x²π(6x)

V = 96πx³

The hole in the middle will be a solid sphere with diameter 2x (radius will be x)

Volume of the hole = 4/3πr³

Volume if the hole = 4/3πx³

Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole

= 96πx³ - 4/3πx³

= (96-4/3)πx³

= 284/3 πx³

Answer:

Step-by-step explanation:

First, put -4x+y=7 into y=mx+b format

move -4x to the other side (or add 4x on both sides)

y=4x+7

now, parallel lines have the same slopes, but not the same y intercepts.

So, you already know the slope of your new line

y=4x+b

now we need to find b (y intercept)

take the point (4,-3) and put it into the equation above

-3=4(4)+b

-3=16+b

move 16 to the other side (or subtract 16)

-19=b

therefore the new line will be y=4x-19

The lifespans of lions in a particular zoo are normally distributed. The average lion lives 12.5 years; the standard deviation is 2.4 years. Use the empirical rule (68-95-99.7\%)(68−95−99.7%) to estimate the probability of a lion living between 5.3 to 10. 1 years.

Answer:

Thehe probability of a lion living between 5.3 to 10. 1 years is 0.1585

Step-by-step explanation:

The empirical rule formula states that:

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

3) 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Mean is given in the question as: 12.5

Standard deviation : 2.4 years

We start by applying the first rule

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

μ - σ

12.5 -2.4

= 10.1

We apply the second rule

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

μ – 2σ

12.5 - 2 × 2.4

12.5 - 4.8

= 7.7

We apply the third rule

3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

μ - 3σ

= 12.5 - 3(2.4)

= 12.5 - 7.2

= 5.3

From the above calculation , we can see that

5.3 years corresponds to one side of 99.7%

Hence,

100 - 99.7%/2 = 0.3%/2

= 0.15%

And 10.1 years corresponds to one side of 68%

Hence

100 - 68%/2 = 32%/2 = 16%

So,the percentage of a lion living between 5.3 to 10. 1 years is calculated as 16% - 0.15%

= 15.85%

Therefore, the probability of a lion living between 5.3 to 10. 1 years

is converted to decimal =

= 15.85/ 100

= 0.1585

Answer:

The probability of a particular lion living less than 10.1 years is 16%

The general solution to the linear system Ax = b is X = Xp + Xn, where Xp = [3, -1, 0]T and Xn = [t, s, t]T.

Given the coefficient matrix A and the constant vector b, we can set up the augmented matrix [A|b] and perform row operations to find the row-echelon form. The row-echelon form will help us determine the particular solution Xp and the solution Xn.

Performing row operations on the augmented matrix [A|b], we have:

[1 2 -1 | 3]

[2 -2 2 | -3]

[3 3 3 | 0]

After performing row operations, we obtain the row-echelon form:

[1 2 -1 | 3]

[0 -6 4 | -9]

[0 0 0 | 0]

From the row-echelon form, we can determine that the system has a free variable, which means it has infinitely many solutions. The associated homogeneous system of equations has a solution of the form Xn = [t, s, t]T, where t and s are free variables.

To find the particular solution Xp, we set the free variables to 0 and solve for the remaining variables in the row-echelon form. In this case, we obtain Xp = [3, -1, 0]T.

Therefore, the general solution to the linear system Ax = b is X = Xp + Xn, where Xp = [3, -1, 0]T and Xn = [t, s, t]T.

Answer:

y = -(2/3)m - 2

Step-by-step explanation:

recall that the general equation of a straight line in slope-intercept form is

y = mx + b

where, m is the slope and b is the y - intercept

here we are given that the y - intercept is -2, hence the equation becomes:

y = mx + (-2)

or

y = mx -2

we are also given that the x-intercept is -3, which means that when y = 0, x = -3 (simply substitute this into our new equation to solve for m)

0 = m(-3) -2

0 = -3m - 2  (add 3m to both sides)

3m = -2  (divide both sides by 3)

m = -(2/3)

hence our equation is now

y = -(2/3)m - 2
