Step-by-step explanation:

If 80% of the frogs in a pond are spring peppers, and there are 200 frogs in the pond, to find how many spring peppers are in the pond, find 80% of 200.

[tex]\begin{aligned} \sf \implies 80\% \textsf{ of }200 & = \sf 80\% \times 200\\\\& = \sf \dfrac{80}{100} \times 200\\\\& = \sf \dfrac{80}{100} \times \dfrac{200}{1}\\\\& = \sf \dfrac{80 \times 200}{100 \times 1}\\\\& = \sf \dfrac{16000}{100}\\\\& = \sf 160\end{aligned}[/tex]

Therefore, there are 160 spring peppers in the pond.

The area of the rectangular pink border is of 400 cm².

The area of a rectangle of dimensions l and w is given by the multiplication of the dimensions, as follows:

A = lw.

Hence, the total area is given by:

A = 30 x 20 = 600 cm².

The area of the white region is given by:

A = (30 - 2 x 5) x (20 - 2 x 5) = 20 x 100 = 200 cm².

Hence the area of the pink border is:

600 cm² - 200 cm² = 400 cm².

The solution to the given equation is 3±3√3/2

Given the quadratic equation below

2x^2−6x−9=0

Solve using the general formula to have:

a = 2

b = -6

c = -9

Substitute

x = -b±√b²-4ac/2a

x = -(-6)±√(-6)²-4(2)(-9)/2(2)

x = 6±√36+72/4

x = 6±√108/4

x = 6±6√3/4

x = 3±3√3/2

Hence the solution to the given equation is 3±3√3/2

#1) & #5) are the rates that have the same constant rate of change as Micheal's rate.

Answer:

See below

Step-by-step explanation:

Here is one possible mistake:

Let y= u = ( 2ax^2 +c)^2          expand

        4 a^2 x^4  + 4 a x^2 c   + c^2

  dy/ dx   then becomes  

16 a^2 x^3 + 8 a x c  <====== you have  8 a^2x^3 + 8axc  

   MAYBE ??

[tex]y = (2ax^2 + c)^2 (bx^2 - cx)^{-1}[/tex]

By the product rule,

[tex]\dfrac{dy}{dx} = \dfrac{d(2ax^2+c)^2}{dx} (bx^2-cx)^{-1} + (2ax^2+c)^2 \dfrac{d(bx^2-cx)^{-1}}{dx}[/tex]

For the first derivative on the right side, let [tex]u=2ax^2+c[/tex]. Then by the chain rule,

[tex]\dfrac{d(2ax^2+c)^2}{dx} = \dfrac{du^2}{dx} \\\\ ~~~~~~~~~~~~~~~~~~ = \dfrac{du^2}{du}\dfrac{du}{dx} \\\\ ~~~~~~~~~~~~~~~~~~ = 2u \dfrac{du}{dx} \\\\ ~~~~~~~~~~~~~~~~~~ = 2(2ax^2+c) \dfrac{d(2ax^2+c)}{dx}[/tex]

and by the power rule, this reduces to

[tex]\dfrac{d(2ax^2+c)^2}{dx} = 2 (2ax^2+c) (4ax) \\\\ ~~~~~~~~~~~~~~~~~~ = 8ax (2ax^2 + c)[/tex]

For the other derivative, let [tex]v = bx^2-cx[/tex]. Then

[tex]\dfrac{d(bx^2-cx)^{-1}}{dx} = \dfrac{dv^{-1}}{dx} \\\\ ~~~~~~~~~~~~~~~~~~~~ = \dfrac{dv^{-1}}{dv}\dfrac{dv}{dx} \\\\ ~~~~~~~~~~~~~~~~~~~~ = -v^{-2} \dfrac{dv}{dx} \\\\ ~~~~~~~~~~~~~~~~~~~~ = -(bx^2-cx)^{-2}\dfrac{d(bx^2-cx)}{dx}[/tex]

which reduces to

[tex]\dfrac{d(bx^2-cx)^{-1}}{dx} = -(bx^2 - cx)^{-2} (2bx - c)[/tex]

So one expression for the derivative we want is

[tex]\dfrac{dy}{dx} = 8ax (2ax^2 + c) (bx^2-cx)^{-1} - (2ax^2+c)^2 (bx^2 - cx)^{-2} (2bx - c)[/tex]

The fraction that represents the part of a whole, which is shaded gold is 3/7.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole.

Given is a big green rectangle divided into seven equal segments. From the image, it can be seen that 3 segments out of the seven are colored with gold. Therefore, we can write that -

Number of segments colored = n[c] = 3

Total segments = n[T] = 7

We know that a fraction defines a part of a whole. The green Rectangle is one whole, therefore it can be concluded that -

1 whole = 7 segments = n[T].

Number of segments colored = n[c] = 3.

Therefore, we can say that the fraction that represents the part of a whole, which is shaded gold is given by -

n[c] / n[T] = 3 / 7

Therefore, the fraction that represents the part of a whole, which is shaded gold is 3/7.

Step-by-step explanation:

The given set has 5 elements, meaning it has 2⁵ = 32 subsets.

This means the cardinality of the desired set is 32.

There are 5,000 nails in five boxes. The first and second boxes have 2,700 nails altogether. The second and third boxes have 2,000 nails altogether. The third and fourth boxes have 1,800 nails altogether. The fourth and fifth boxes have 1,700 nails altogether. How many nails are in each box

Purchases of both small and large boxes total:

two little boxes.

six huge boxes

Two equations must be created with the given data in order to answer the unknowns:

150X + 400Y = 2700 (the price of the boxes and the total number of nails, where X is the small boxes and Y the large boxes)

Y = 3X

Equation one is then changed to equation 2, and variable X is eliminated:

150X + 400 (3X) = 2700

150X + 1200X = 2700 1350X = 2700 X = 2700/1350 X = 2

In order to determine the number of big boxes, equation 2's value of X is finally changed:

Y = 3X

Y = 3

Y = 6
