Answer:

P = A / (1 + r/100)ᵗ

Step-by-step explanation:

A = P(1 + r/100)ᵗ

We can make P the subject of the above expression as follow:

A = P(1 + r/100)ᵗ

Divide both side by (1 + r/100)ᵗ

P = A / (1 + r/100)ᵗ

Therefore, making P the subject of

A = P(1 + r/100)ᵗ, we have

P = A / (1 + r/100)ᵗ

Answer:

a) the ratio is 9:4

b) Hilda did save $16.

Step-by-step explanation:

Let's define the variables:

C = Cheryl's savings.

H = Hilda's savings.

We know that:

(1/3)*C = (3/4)*H

We also know that Cheryl saved $36, then we have:

C = $36

Now we can replace that in the above equation to get:

(1/3)*$36 = (3/4)*H

$12 = (3/4)*H

$12*(4/3) = H = $16

Then Hilda did save $16.

And the ratio between of Cheryl's savings to Hilda's savings is:

36 : 16

We can simplify this if we divide both by 2.

(36/2) : 16/2

18 : 8

Again, we can divide both by 2:

(18/2) : (8/2)

9 : 4

Then the ratio is 9 : 4

Step 1: Define

Center (2, -3) → x₁ = 2, y₁ = -3

Circumference point (-1, -2) → x₂ = -1, y₂ = -2

In this case, the distance d from the center to the circumference point would be the radius r of the circle.

D. Rectangular prism

Step-by-step explanation:

I believe the answer is D. Rectangular prism

A rectangular prism is also called a cuboid. Like cuboid, it also has three dimensions, i.e., length, width and height. So here the horizontal cross section of the figure is rectangular prism. The correct option is B.

A rectangular prism is defined as a three dimensional shape which has six faces (two at the top and bottom and four are lateral faces). All the faces of the prism are rectangular in shape. A geometrical box, notebooks, rooms, etc. are in the shape of a rectangular prism.

A rectangular prism has 6 faces, 12 edges and has 8 vertices. For a rectangular prism the pairs of opposite faces are identical or congruent. A prism with six faces that are rectangles and all angles are right angles is a right rectangular prism.

Thus the correct option is B.

Answer: (9, ∞)

Step-by-step explanation:

You cant take the natural log of a negative number, and you cant take the natural log of 0. So, to find the intervals where the function is defined, set the inside of the natural to 0.

9x - 81 = 0

x = 9

The intervals where this function is continuous is from 9 --> infinity

Answer:

y = 125

Step-by-step explanation:

Given that,

y is directly proportional to x² i.e.

[tex]y=kx^2[/tex]

k is a constant of proportionality

Put y = 20 and x = 2 in the given equation to find k.

[tex]k=\dfrac{y}{x^2}\\\\k=\dfrac{20}{(2)^2}\\\\k=5[/tex]

Now put k = 5 and x = 5 in the given equation to find y.

[tex]y=5\times (5)^2\\\\y=125[/tex]

So, the value of y is equal to 125.

Answer:

[tex]t = \frac{1}{4}\sqrt d[/tex]

Time to reach 100ft is 2.5 seconds

Step-by-step explanation:

Given

[tex]d = 16t^2[/tex]

Solving (a): Determine the inverse function

[tex]d = 16t^2[/tex]

Swap the positions of d and t

[tex]t = 16d^2[/tex]

Make d the subject

[tex]\frac{t}{16} = d^2[/tex]

Take positive square root of both sides

[tex]\sqrt{\frac{t}{16}} = d[/tex]

[tex]d = \sqrt{\frac{t}{16}}[/tex]

[tex]d = \frac{1}{4}\sqrt t[/tex]

Swap the positions of d and t

[tex]t = \frac{1}{4}\sqrt d[/tex] --- The inverse function

Solving (b): Find t when d =100

Substitute 100 for d in [tex]t = \frac{1}{4}\sqrt d[/tex]

[tex]t = \frac{1}{4}\sqrt {100[/tex]

[tex]t = \frac{1}{4}* 10[/tex]

[tex]t = \frac{1* 10}{4}[/tex]

[tex]t = \frac{10}{4}[/tex]

[tex]t = 2.5[/tex]

Answer:

a.)

Number of bushes = b = 129 + 4(7) = 129 + 28 = 157 bushes

b.)

Revenue = bx = (157)(31.4) = $ 4929.8

Step-by-step explanation:

Let number of bushes = b

The price of the bushes = x

The time to harvest = t

The revenue = y

Now given,

Price = x = 37 - (0.8)t

and

Number of bushes = b = 129 + 4t

Also,

The revenue = (Number of bushes)(Price of the bushes)

                     = bx

                     = (129 + 4t)[37 - (0.8)t]

                     = 129×37 - 129× (0.8)t + 4×37t - 4×0.8t²

                     = 4773 - 103.2t + 148t - 3.2t²

                     = 4773 + 44.8t - 3.2t²

⇒ y = 4773 + 44.8t - 3.2t²

Now,

[tex]\frac{dy}{dt}[/tex] = 0 + 44.8 - 6.4t

Now,

[tex]\frac{dy}{dt}[/tex] = 0

⇒ 44.8 - 6.4t = 0

⇒ - 6.4t = -44.8

⇒ 6.4t = 44.8

⇒t = [tex]\frac{44.8}{6.4} = 7[/tex]

Now,

[tex]\frac{d^{2}y }{dt^{2} }[/tex] = -6.4

As [tex]\frac{d^{2}y }{dt^{2} }[/tex]  < 0 ,

It means at time t = 7 , the revenue is maximum

a.)

Number of bushes = b = 129 + 4(7) = 129 + 28 = 157 bushes

Price = x = 37 - (0.8)(7) = 37 - 5.6 = 31.4

b.)

Revenue = bx = (157)(31.4) = 4929.8

Answer:

Answer is 268435456

Step-by-step explanation:

use an = a × ^r n-1 to find the sequence

The 15th term of the given geometric progression sequence 1, -4, 16, ... will be 268435456.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given sequence,

1, -4, 16, ...

First term a = 1

Common ratio r = -4/1 = -4

The nth term is given as ar^(n - 1)

Therefore, the 15th term will be as,

a₁₅ = 1(-4)¹⁵⁻¹

a₁₅ = -4¹⁴ = 268435456

Hence "The 15th term of the given geometric progression sequence 1, -4, 16, ... will be 268435456".

Answer:

They complete the hill in 8 hours

Step-by-step explanation:

Equations:

Let's call the variables:

Aran can make build the ant hill in A hours

Beatrice can make build the ant hill in B hours

Charlie can make build the ant hill in C hours

In one hour, Aran makes 1/A of the ant hill.

In one hour, Beatrice makes 1/B of the ant hill.

In one hour, Charlie makes 1/C of the ant hill.

Aran and Beatrice build it in 10 hours, thus:

[tex]\displaystyle \frac{1}{A}+\frac{1}{B}=\frac{1}{10}\qquad\qquad[1][/tex]

Similarly:

[tex]\displaystyle \frac{1}{A}+\frac{1}{C}=\frac{1}{12}\qquad\qquad[2][/tex]

[tex]\displaystyle \frac{1}{B}+\frac{1}{C}=\frac{1}{15}\qquad\qquad[3][/tex]

We need to find the time taken for the three ants to build the anthill:

[tex]\displaystyle \frac{1}{A}+\frac{1}{B}+\frac{1}{C}=[/tex]

Adding [1], [2], and [3]:

[tex]\displaystyle \frac{2}{A}+\frac{2}{B}+\frac{2}{C}=\frac{1}{10}+\frac{1}{12}+\frac{1}{15}[/tex]

Adding the fractions (LCM=60):

[tex]\displaystyle \frac{2}{A}+\frac{2}{B}+\frac{2}{C}=\frac{6}{60}+\frac{5}{60}+\frac{4}{60}[/tex]

[tex]\displaystyle \frac{2}{A}+\frac{2}{B}+\frac{2}{C}=\frac{6+5+4}{60}=\frac{15}{60}=\frac{1}{4}[/tex]

Dividing by 2:

[tex]\displaystyle \frac{1}{A}+\frac{1}{B}+\frac{1}{C}=\frac{1}{8}[/tex]

All ants together make 1/8 of the hill, thus they complete the hill in 8 hours
