You estimate that your new business's revenue will grow at a compounded rate of 30% each month for the first 6 months. If your third month's revenue is estimated at $5,000, what is your second month's revenue? (Round to the nearest dollar.)
a) $2,945
b) $3,846
c) $4,012
d) $4,333
Answer:
b
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
let a = second month's revenue
5000 = a(1.3)
a = 5000 / 1.3 = 3846

To do this, we make of sine rule.
[tex]\frac{a}{\sin A} = \frac{b}{\sin B} =\frac{c}{\sin C}[/tex]
In this case:
[tex]x = ??[/tex]
[tex]X = 68[/tex]
[tex]a = 66[/tex]
[tex]A = 35[/tex]
So, we have:
[tex]\frac{x}{\sin 68} = \frac{66}{\sin 35}[/tex]
Make x the subject
[tex]x = \frac{66}{\sin 35} * \sin 68[/tex]
Using a calculator, we have:
[tex]x = \frac{66}{0.5736} * 0.9272[/tex]
[tex]x = 115.063* 0.9272[/tex]
[tex]x = 106.68[/tex]
[tex]x \approx 107[/tex]

Given:
length of rectangle = 4 units
Height of rectangle = 2x + 6 units
To find:
Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.
Steps:
Perimeter of rectangle = 2(L + B)
= 2( 4 + 2x + 6 )
= 2( 10 + 2x )
= 2 * 10 + 2 * 2x
= 20 + 4x units
Area of rectangle = L * B
= 4 * (2x + 6)
= 4 * 2x + 4 * 6
= 8x + 24 units²
Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².
Happy to help :)
If you need any help, feel free to ask.
Answer:
we multiply 4 by 2x + 6
4(2x + 6) = 8x + 24
En france en 1900 la taille moyennes des femmes etait de 1,54 m et celle des hommes de 1,66 m. Entre 1900 et 2010 ces tailles moyeness ont augmentes de 5,55 %
Complete question :
En France, en 1900, la taille moyenne des femmes était de 1,54 m et celle des hommes de 1,66 m. Entre
1900 et 2010 ces tailles moyennes ont augmentées d'environ 5,55%.
Calculer, en mètres, l'arrondi au centième des tailles moyennes des femmes et des hommes en 2010.
Répondre :
Femmes = 1,63
Hommes = 1,75 m
Explication étape par étape:
Étant donné que :
Taille moyenne en 1900:
Hommes = 1,66 m
Femmes = 1,54 m
Pourcentage d'augmentation de poids d'ici 2010 = 5,55%
1 + 5,55% = 1 + 0,0555 = 1,0555
D'où,
Taille des femmes en 2010:
1,0555 * 1,54 = 1,62547 = 1,63 m
Pour la taille des hommes en 2010:
1,0555 * 1,66 m = 1,75213 = 1,75 m

Answer:
The answer is below
Step-by-step explanation:
The question is not complete, a complete question is attached.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled, obtuse, acute, scalene, isosceles, equilateral triangle.
Trigonometric identities are used to show the relationship between the sides and the angles in a right angled triangle. Below are some trigonometric identities:
sin(θ) = opposite / hypotenuse; cos(θ) = adjacent / hypotenuse; tan(θ) = opposite / adjacent
The hypotenuse is the longest side in the triangle.
From the image attached:
sin(α) = opposite side / hypotenuse side
sin(α) = 7 / 25

Step-by-step explanation:
Given:
Number of fabric sample = 6 sample
Number of floral sample from all samples = 2 samples
Find:
Probability of selected sample is floral
Computation:
Probability of a sample = Favorable outcome / Total outcomes
Probability of selected sample is floral = Number of floral sample / Number of fabric sample

A slightly more accurate value is 38.28 cm^2, when using pi = 3.14
=================================================
Explanation:
The vertical height of the rectangle is 4 cm, which forms the diameter of the semicircle. The diameter cuts in half to 4/2 = 2, which is the radius.
The area of a full circle with radius r = 2 cm is approximately pi*r^2 = 3.14*2^2 = 12.56 square cm.
Cut that in half to get (12.56)/2 = 6.28 square cm. This is the approximate area of the semicircle.
--------
The area of the rectangle is length*width = 6*4 = 24 square cm.
The triangle has its bottom portion of 4 cm (because 10-6 = 4) and its height is 4 cm, so we get the triangle area of base*height/2 = 4*4/2 = 8 square cm.
The last thing we do is add up all the results we got:
6.28 + 24 + 8 = 38.28
That rounds to 38 square cm when rounding to the nearest whole number.

Find the area of the shaded region
Answer:
40
Step-by-step explanation:
area of shaded region = area of whole figure - area of non shaded region
area of whole figure: The whole figure is a rectangle
The area of a rectangle can simply be calculated by multiplying the width by the length
The given width is 10ft and the given length is 8ft
Hence area of whole figure = 10 * 8 = 80ft²
Area of non shaded region: the non shaded region also creates a rectangle
Like stated previously the area of a rectangle can simply be calculated by multiplying the width by the length
The given width is 5ft and the given length is 8ft
Hence, area of non shaded region = 5 * 8 = 40ft²
Finally we can find the area of the shaded region.
We can easily do this my subtracting the area of the nonshaded region from the area of the whole figure
If we have identified that the area of the whole figure is 80 and the area of the non shaded region is 40
Then, area of shaded region = 80 - 40 = 40ft²

Let measure of angle B be 18 degrees and BC = 9. Find the length of AC, BA and the measure of angle C. Round to 1 decimal place when needed. Show all of your work.
Answer:
m∠C = 72°
BA = 8.6
AC = 2.8
Step-by-step explanation:
We can start by finding the sum of all angles in a triangle to find angle C. The sum of all angles is 180°, so we can write the equation:
m∠A + m∠B + m∠C = 180°
And substitute what we have:
90° + 18° + m∠C = 180°
108° + m∠C = 180°
m∠C = 72°
In order to find the side BA, we can use trig functions. We are given the hypotenuse and we are looking for the side adjacent to ∠B. The trig function that relates the two is cosine. We can set up the equation as follows:
cos(∠B) = [tex]\frac{BA}{BC}[/tex]
cos(18°) = [tex]\frac{BA}{9}[/tex]
9 * cos(18°) = BA
BA ≈ 8.559508647
And when we round, we get:
BA = 8.6
In order to find the side AC, we can use trig functions. We are given the hypotenuse and we are looking for the side opposite to ∠B. The trig function that relates the two is sine. We can set up the equation as follows:
sin(∠B) = [tex]\frac{AC}{BC}[/tex]
sin(18°) = [tex]\frac{AC}{9}[/tex]
9 * sin(18°) = AC
AC ≈ 2.781152949
We can round this to:
AC = 2.8
