The domain of the exponential function in this problem is given as follows:

0 ≤ n ≤ 5.

How to obtain the domain of the exponential function?

The exponential function in this problem is defined by the rule presented as follows:

g(n) = 10(1.02)^n.

In which the variables are listed as follows:

n is the number of days.g(n) is the height of flower after n days.

When the study was finished, the height of the flower was of 11.04 inches, hence the day at which the study was finished is obtained as follows:

10(1.02)^n = 11.04

(1.02)^n = 11.04/10

log[(1.02)^n] = log(11.04/10)

Applying the logarithm of power property, we have that:

nlog(1.02) = log(11.04/10)

n = log(11.04/10)/log(1.02)

n = 5.

The domain is the number of days for which the student was realized, hence:

0 ≤ n ≤ 5.

As the number of days cannot assume negative values.

A plane has a cruising speed of 200 miles per hour when there is no wind. At this speed, the plane flew 500 miles with the wind in the same
amount of time it flew 300 miles against the wind. Find the speed of the wind.

Answers

The speed of the wind is 50 mile per hour  .

In the question ,

it is given that

the speed of the plane is [tex]=[/tex] 200 miles per hour .

let the speed of the wind is = "w"

So ,the speed of the plane with wind is [tex]=[/tex] 200 + w

and the speed of the plane against  wind is [tex]=[/tex] 200 - w

we know that , distance [tex]=[/tex] speed × time

the plane flew "500 miles" with wind ,

which means ,

500 [tex]=[/tex] (200 + w) × t      .....(1)

and the plane flew 300 miles against the wind ,

which means ,

300 [tex]=[/tex] (200 - w) × t       ......(2)

adding both the equations ,

we get

800 [tex]=[/tex] t ( 200 [tex]+[/tex] w [tex]+[/tex] 200 - w)

800 = t × 400

t = 2

Substituting  , t = 2 in 500 [tex]=[/tex] (200 + w) × t      

we get

500 = (200 + w) × 2

500/2 = 200 + w

250 = 200 + w

w = 250 - 200

w = 50

Therefore , The speed of the wind is 50 mile per hour  .

a banana weighs 140 g a pineapple weighs 345 g bag a contains 8 bananas and bag b contains 3 pineapples which bag weighs more and by how much show your working

Answers

Answer:

Bag a, by 85 grams!

Step-by-step explanation:

1) Work out the weight of bag a

1 banana is 140 grams so to find out 8 you have to multiply them

140 x 8 = 1120

Bag a = 1120 grams

2) Work out the weight of bag b

1 pineapple weight 345 grams so to find out 3 you have to multiply them just like above

345 x 3 = 1035

Bag b = 1035

3) Find the difference

Bag a is 1120 grams and bag b is 1035

To find out out by how much you just have to subtract them

1120 - 1035 = 85

Answers

The measurements of the rectangle are 10 cm and 5cm.

What is rectangle?

A rectangle could be a quadrilateral with four right angles in geometer geometry. It may be outlined as an angulate quadrilateral as a result of all of its angles square measure equal; or a quadrangle with a right angle.

Main Body:

Let the width be x.

According to question :

width is 5 more than 1 times the length(l), so

length (l) = width -5

Area if rectangle = 50 cm²

Formula for area of rectangle = length * width

⇒50 = x*(x-5)

⇒50 = x² - 5x

⇒x² - 5x - 50 =0

splitting the middle term

⇒x²- 10x +5x -50 = 0

⇒x(x-10) +5(x-10)

⇒(x-10)(x+5)

Hence the value for x = 10 or -5 .

but length can never be -ve so x= 10.

Width = 10 cm

length = width -5

length = 10 -5

l = 5cm

Hence Measurements of rectangle are 10cm and 5cm.

the radius of a sphere is increasing at a rate of 4 mm/s. how fast is the volume increasing (in mm3/s) when the diameter is 80 mm? (round your answer to two decimal places.)

Answers

Increase in volume is 802424.77 cubic mm/s when the diameter is 80 mm.

Let the radius of the sphere be R.

So, the volume of the sphere is given by,

V = [tex]\frac{4}{3}\pi r^3[/tex]

Differentiating the above relation with respect to time 't' we get,

dV/dt = 4[tex]\pi r^2[/tex]. dr/dt

Given that, the change of radius (dr/dt) = 4 mm/s

When the diameter is 80 mm, then the radius = 80/2 = 40 mm

So the volume change when the diameter is 80 mm is given by,

dV/dt [tex]=4\pi\times40^2\times4\approx 802424.77[/tex] cubic mm/s

Dominic needs a new bike mirror. His old mirror was a square with a side length of 9 cm. He wants the new mirror to have an area as close as possible to his old bike mirror.
Which circular bike mirror should Dominic buy? Answer Choices: 8 cm , 7 cm , and 6 cm Answer ASAP FOR Brainlist.

Answers

Answer:

6 cm

Step-by-step explanation:

The circular mirror Dominic should buy is the mirror with a side length of

8 cm.

Option A is the correct answer.

What is a square?

A Square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Old mirror.

Side = 9 cm

Area = 9 x 9 = 81 cm²

New mirror.

Side = 8 cm

Area = 64 cm²

Side = 7 cm

Area = 7 x 7 = 49 cm²

Side = 6 cm

Area = 6 x 6 = 36 cm²

64 cm² is closer to 81 cm².

Thus,

A circular mirror with a side length of 8 cm should be bought.

Equation of parabola with vertex (h,k)


The equation of a parabola with vertex given by (h,k) is presented as follows:

y = a(x - h)² + k.

In which a is the leading coeffiicent.

For item 1, the coordinates of the vertex is given as follows:

(4,-1).

Hence:

h = 4, k = -1, and the equation is:

y = a(x - 4)² - 1.

When x = 6, y = 6, hence the leading coefficient is calculated as follows:

6 = a(6 - 4)² - 1

4a = 7

a = 7/4.

Thus the equation is:

y = 7/4(x - 4)² - 1.

For item 2, the vertex is:

(-1,2).

Hence:

y = a(x + 1)² + 2.

When x = 0, y = 0, hence the leading coefficient is calculated as follows:

First, describe the area formulas for the rectangles ABCD and APQD, both in square centimeters:

Rectangle ABCD

g · f = 24                 (2)

Where:

g - Length of the side QD, in centimeters. f - Length of the side BC, in centimeters.

Second, use distributive property in (1):

By (1):

g · f + 9 · f = 60

Third, use substitution by (2) on (1) and determine the value of f:

(2) in (1):

24 + 9 · f = 60

Answers

When the number of people is multiplied by 4, the number of pizzas is multiplied by 4.

What is a ratio?

A ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

What is a proportion?

A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

Mathematically, a proportional relationship can be modeled by the following mathematical expression:

y = kx

x represents the number of people.y represents the number of pizzas needed.k represents the constant of proportionality.

If the x-value is multiplied by 4, we have:

x = 5 × 4

x = 20

From the corresponding y-value for 20 is equal to 8 and as such the number of pizzas needed should be multiplied by 4, in order to produce an equivalent ratio.

Reflect the figure over the line y=1/3x+1

Answers

Answer:

  see the attachment

Step-by-step explanation:

You want a graph of the given figure reflected over the line y = 1/3x +1.

Line of reflection

The given line of reflection can be written in general form as ...

  y = 1/3x +1

  3y = x +3 . . . . . . multiply by 3

  x -3y +3 = 0 . . . . subtract 3y

This is in the general form ...

  ax +by +c = 0

where a=1, b=-3, c=3.

The line of reflection is the perpendicular bisector of the segment joining a point (x, y) with its reflection (x', y').

Reflected point

Using the formula in the second attachment, we find the reflection

  (x1, y1) ⇒ (x, y)

satisfies ...

  (x -x1)/a = (y -y1)/b = -2(ax1 +by1 +c)/(a² +b²)

or ...

  x = -2a/(a²+b²)·(ax1 +by1 +c) +x1

  y = -2b/(a²+b²)·(ax1 +by1 +c) +y1

Using the known values for a, b, c, we have ...

  x = -2(1)/(1² +(-3)²)·(x1 -3y1 +3) +x1 = (1/5)(4x1 +3y1  -3)

  y = -2(-3)/10·(x1 -3y1 +3) +y1 = (1/5)(3x1 -4y1 +9)

Rewriting the mapping in more conventional terms, we have ...

  (x, y) ⇒ ((4x +3y -3)/5, (3x -4y +9)/5)

It is convenient to let a spreadsheet do the repetitive tedious math. The third attachment shows the application of this mapping to the coordinates of the figure's vertices (clockwise from bottom).
