The time taken by 5 large solar panels and 3 small solar panels to charge a car, found using the unitary method, is 576 minutes.

The unitary approach is a method for problem-solving that involves first determining the value of a single unit, and then determining the necessary value by multiplying the single unit value.

Given

Time taken by 2 large solar panels to charge a car = 240 minutes

Time taken by 2 large solar panels to charge a car

       = Time taken by 6 small solar panels to charge a car = 240 minutes

The unitary method can be used to find the charging times of 1 large and 1 small solar panel.

The time taken by 1 solar panel is greater than time taken by 2 large and 6 small solar panels.

Time taken by 1 small solar panel = 240 * 6 = 1440 minutes

Time taken by 1 large solar panel = 240 * 2 = 480 minutes

Therefore the time taken by 5 large solar panels and 3 small solar panels to charge a car = (480/5)+ (1440/3) =96 + 480= 576 minutes.

The Volume of shape Q is 25,600 cm³.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.

Given:

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared.

Let z be the scale factor

x be the surface area of shape Q

and, y be the surface area of shape P

So, z²=x/y

we have,

x = 2880 cm², y= 720 cm²

z² = 2880/720

z² = 4

z = 2

Now, If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

z³ = x/y

We have z= 2 and y = 3200 cm³

So, 2³ = x/3200

x = 8×3200

The length of the beach towel is 4.135 feet.

Area of a two dimensional shape is the total region which is bounded by the object's shape

Given that

Hugo needs a total of 22.23 square feet of terry cloth to make a beach towel and a beach bag.

Total area of the terry cloth = 22.23 square feet

The beach bag requires 5.13 square feet of cloth.

Area of cloth for beach bag = 5.13 square feet

Area of the cloth for beach towel = 22.23 - 5.13 = 17.1

Area of the beach towel is 17.1 square feet.

Assuming the towel is square shape,

Where:

At data point (0, 4), a linear equation of the first line can be calculated in slope-intercept form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 4 = (5 - 4)/(3 - 0)(x - 0)

y = x/3 + 4

No, the square root of 1 is 1, but 1 is not equal to the square root of 1. The square root of a number, represented by the symbol √, is a value that, when multiplied by itself, gives the original number.

For example, the square root of 4 is 2, because 2 x 2 = 4. In the case of 1, the square root is also 1, because 1 x 1 = 1.

In mathematics, the square root of a number is always non-negative, real number. It is positive for positive numbers and zero for zero. So, in short, the square root of 1 is 1, but 1 is not equal to the square root of 1. It is just a value that gives 1 when multiplied with itself.

It's important to note that the square root is not a number but an operator, an action which you perform on a number. The square root of a number is a value that, when multiplied by itself, gives the original number.

In this case, the square root of 1 is 1, which means that 1 multiplied by 1 is 1.

Also, it's worth mentioning that there are two types of square roots: principal square root and non-principal square roots. Principal square root is the positive value of the square root and non-principal square roots are the negative value of the square root.

In this case, the square root of 1 is 1, which is the positive value of the square root.

From the question, we have the following parameters that can be used in our computation:

y = 2ln(k - 3x) + x^2 - 3x

The x-axis is the set of points where y = 0. To find where the curve crosses the x-axis, we need to solve the equation y = 0 for x.

y = 2ln(k - 3x) + x^2 - 3x

so

0 = 2ln(k - 3x) + x^2 - 3x

We can re-arrange this equation to solve for x:

x^2 - 3x + 2ln(k - 3x) = 0

Now we can use the quadratic formula to find x.

x = (3 +/- sqrt(3^2 - 4(2ln(k - 3x))))/2

Now we know that there is only one root, we can pick the positive value and solve for k using k-3x = e^(x^2-3x/2)
