Answer:
We can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the final amount
P = the principal amount (initial investment)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time period in years
In this case, we have:
P = £1430
r = 0.005 (0.5% per month)
n = 12 (compounded monthly)
t = 9/12 = 0.75 (9 months is three-quarters of a year)
So we can plug in these values to find the final amount:
A = £1430(1 + 0.005/12)^(12*0.75)
A ≈ £1481.18
Therefore, the amount of money in the account after 9 months will be approximately £1481.18.

The answer is 4 but I don’t understand why the graph is starting at -2.
Answer:
graph 4 (reflected vertically)
Step-by-step explanation:
You want the graph that represents a cosine function with no horizontal shift, an amplitude of 2, and a period of 2π/3.
AmplitudeThe amplitude of a sine or cosine function is the difference between the positive peak and the centerline. All of the graphs show functions with an amplitude of 2.
Period/FrequencyThe period of the function is the difference of x-values between the first instance of the function and the first repeat: f(x) ≡ f(x+p) has a period of p.
Graphs 1 and 3 show periods of 2π/9; graphs 2 and 4 show periods of 2π/3, as required.
Horizontal shiftThere is an interaction between horizontal shift and vertical reflection. Sine or cosine functions are effectively inverted (reflected over the x-axis) if they are shifted horizontally by 1/2 period—and vice versa.
The function in graph 3 is a sine function, or a horizontally shifted cosine function.
The function in graph 4 is a cosine function that has been shifted 1/2 perior, OR a cosine function that has been reflected over the x-axis.
Graph 4 is the only viable choice for a cosine function with the correct period, so we have to assume it starts at -2 because it has been reflected vertically over the x-axis. (There seems to be no restriction on that in the problem statement.)

Additional comment
Ordinarily, you might not be expected to make any assumptions about vertical reflection. It seems a bit of a trick question.
The average width of a movie theater seat is 23 inches. Thirty years ago, the typical movie theater seat was approximately 19 inches wide. Current movie theater seats are what percent of a theater seat from 30 years ago?
Thus, the current movie theater seats are 21.05 % of a theater seat from 30 years ago.
Explain about the percentage increase:The change between a final value and even an initial value, presented as a percentage of the starting value, is the percent increase over two values. Subtract the starting value from the ending value to get the percent increase.
Next, divide the difference by the starting amount. In order to convert this value to a percentage, multiply it by 100%. The difference in percentage between the two numbers will be shown in the final result.
Given data:
width of current movie theatre seat = 23 inches.
width of 30 years ago movie theatre seat = 19 inches.
Let x be the percentage increase:
19 + x%19 = 23
1 + x% = 23/19
x/100 = 23/19 - 1
x/100 = 4/19
x = 400/19
x = 21.05 %
Thus, the current movie theater seats are 21.05 % of a theater seat from 30 years ago.

(2) Eduardo wrote at least 34 pages before today.
(3) The farmer needs to plant at least 8 rows of seeds to harvest at least 52 bushels of tomatoes.
What is the solution to the inequality 7 ≤ n + 5?The solution to the inequality 7 ≤ n + 5 is as follows:
7 ≤ n + 5
collect similar terms together
7 - 5 ≤ n
2 ≤ n
So we can interpret the result of this inequality as, n is greater than and equal to 2. Hence option A is the correct answer.
2. Let p be the number of pages Eduardo wrote before today. Then, the inequality that represents the situation is:
p + 16 > 50
To solve for p, first subtract 16 from both sides of the inequality:
p + 16 - 16 > 50 - 16
p > 34
Therefore, Eduardo wrote at least 34 pages before today.
3. Let r be the number of rows of seeds the farmer needs to plant. Then, the equation that represents the situation is:

Answer:
To determine when each company is projected to break even, Jami needs to find the point where the Cost and Revenue equations intersect. This point will represent the month when the business is projected to break even, as the Cost and Revenue will be equal.
Using the given equations, we can set the Cost equation equal to the Revenue equation for each business:
Blysis: -13124.3190x + 3586 = -6941915384x + 21954
Solving for x, we get x = 0.00057 months.
Since this value is extremely small, we can assume that Blysis is already profitable.
Appster: -13124.3190x + 3586 = -6941915384x + 21954
Solving for x, we get x = 0.00057 months.
Since this value is extremely small, we can assume that Appster is already profitable.
Enrich: -3586x - 21954 = -6941915384x + 13174
Solving for x, we get x = 0.0035 months.
Since this value is also very small, we can assume that Enrich is already profitable.
Green Team: 178420.64421x - 68419 = -4289115387x + 13174
Solving for x, we get x = 0.0009 months.
Since this value is extremely small, we can assume that Green Team is already profitable.
Southwest Fusion: -13124.3190x + 4289115387x = 13174
Solving for x, we get x = 35.23 months.
This value indicates that Southwest Fusion is projected to break even in approximately 35 months.
Zoo to You: -13124.3190x + 54209539 = -10381x
Solving for x, we get x = 4.05 months.
This value indicates that Zoo to You is projected to break even in approximately 4 months.
Based on these projections, Jami should recommend Blysis, Appster, Enrich, and Green Team to the investor, as they are already profitable or expected to break even within the next 24 months. Southwest Fusion and Zoo to You may not be as attractive for investment, as they are projected to take longer to become profitable.

Answer: 36 m²
Step-by-step explanation:
First, we will solve for the area of the triangles. Since they are congruent, we will multiply the height times the base. Usually, you would have to divide by two. However, since we have two congruent triangles, we will not be doing this.

In the end, Reggie has 435.2 stamps and Cοrwin has 179.2 stamps.
What are the basic mathematical οperatiοns?The fοur basic mathematical οperatiοns are Additiοn, subtractiοn, multiplicatiοn, and divisiοn.
Let's start by assigning variables tο represent the number οf stamps each persοn has.
Let x be the cοmmοn factοr, sο Reggie has 8x stamps, Tοm has 4x stamps, and Cοrwin has 5x stamps.
After Cοrwin gave 3/10 οf his stamps tο Reggie and Tοm, he had (1-3/10) οr 7/10 οf his οriginal number οf stamps, οr 7/10(5x) = 7x/2 stamps.
Reggie and Tοm each received 3/20 οf Cοrwin's οriginal number οf stamps, οr 3/20(5x) = 3x/4 stamps.
Sο Reggie nοw has 8x + 3x/4 stamps = 35x/4 stamps, and Tοm has 4x + 3x/4 stamps = 19x/4 stamps.
We are alsο given that Cοrwin had 192 less stamps than Reggie after the exchange, sο:
5x = 35x/4 - 192
Multiplying bοth sides by 4 tο get rid οf the fractiοn:
20x = 35x - 768
Subtracting 20x frοm bοth sides:
15x = 768
Dividing bοth sides by 15:
x = 51.2
Sο Reggie has 8x = 409.6 stamps, Tοm has 4x = 204.8 stamps, and Cοrwin has 5x = 256 stamps.
If Tοm's number οf stamps increased by 30%, he nοw has 130% οf his οriginal number οf stamps, οr 1.3(204.8) = 266.24 stamps.
Finally, adding up the number οf stamps each persοn nοw has:
Reggie: 409.6 + 3x/4 = 409.6 + 3(51.2)/4 = 435.2 stamps
Tοm: 266.24 stamps
Cοrwin: 7x/2 = 7(51.2)/2 = 179.2 stamps

Since the question is asking about total employees, we must add 175 to 500 to get 675. Therefore, the correct answer is 675.
What does increase mean?Increase means to grow or make larger in size, amount, degree, or intensity. It is the opposite of decrease, meaning to make or become less.
This is because when there were 500 employees, a 35% increase would be a total of 500 + 35% of 500
= 500 + 175
= 675.
To calculate 35% of 500, we use the formula:
(35/100) × 500 = 175
This means that 35% of 500 is 175, so when we add 175 to 500, we get 675.
Since the question is asking about total employees, we must add 175 to 500 to get 675.
Therefore, the correct answer is 675.

A line in the coordinate plane has the equation 5a + b = 7,
where a represents the independent variable, and b
represents the dependent variable. Which of the following is
the equation of a line that is perpendicular to 5a+b=7?
A. b=5a+3
B. b=-5a-5
C. b= (1/5)a-2
D. b=(-1/5)a + 1
Explanation:
I'll use x in place of 'a'
I'll also use y in place of b.
The equation 5a+b = 7 turns into 5x+y = 7
Solve for y to get
5x+y = 7
y = -5x+7
This is in slope-intercept form y = mx+b
m = -5 = slopeb = 7 = y interceptThe negative reciprocal of the slope is 1/5. Flip the fraction and flip the sign. So if -5 is the original slope, then 1/5 is the perpendicular slope.
Of the answer choices, only choice C has a slope of 1/5. Think of b = (1/5)a-2 as y = (1/5)x - 2
Therefore, choice C is the answer.
The equation of a line that is perpendicular to '5a+b = 7' is 'b = (1/5)a + c'. Therefore, the correct option among given choices is 'b = (1/5)a - 2' (option C).
Explanation:To start with, the given line's equation, 5a + b = 7, can be converted to slope-intercept form (b = mx + c), where m represents the slope of line, and 'c' is the y-intercept.
Converting the equation, 5a + b = 7, we get b = -5a + 7. This tells us the slope of our original line is -5.
Lines that are perpendicular to each other have slopes that are negative reciprocals of each other. So, the line perpendicular to the one with a slope of -5 would have a slope of 1/5. Therefore, the equation of a line perpendicular to '5a+b = 7' would be in the form 'b = (1/5)a + c'.
Thus, the correct answer is option C : b = (1/5)a - 2.

A certain drug is made from only two ingredients: compound A and B. There are 5 milliliters of compound A used for every 7 milliliters of compound B. If a chemist wants to make 1104 milliliters of the drug, how many milliliters of compound a needed?
Answer:
460 milliliters
Step-by-step explanation:
We know that the ratio of A to B is 5:7. This means for every 5 milliliters of A, we need 7 milliliters of B. Let's use this ratio to find how many milliliters of A we need for 1104 milliliters of the drug.
First, we need to find out how many sets of 5:7 we have in 1104 milliliters. We can do this by dividing 1104 by the total number of parts in the ratio, which is 5 + 7 = 12.
1104 / 12 = 92
This means we have 92 sets of 5:7 in 1104 milliliters of the drug. To find how many milliliters of A we need, we simply multiply the number of sets by the amount of A in each set, which is 5 milliliters.
92 x 5 = 460
Therefore, we need 460 milliliters of compound A.

3x² - 2x + 15x - 10 by grouping.
3x² - 2x + 15x - 10
=____(3x − ___) +___(___ — ____)
=(___+___)(____ — _____)
3x² - 2x + 15x - 10 can be factored by grouping as:
3x² - 2x + 15x - 10
= (3x - 2)(x + 5)
Explanation:
Group the first two terms and the last two terms together:
(3x² - 2x) + (15x - 10)
Factor out the GCF from each group:
3x(x - (2/3)) + 5(3x - 2)
Now we have a common factor of (3x - 2):
(3x - 2)(x + 5)

Area of shaded factor = (fraction) ft
Area of unshaded factor = (fraction) ft
The area of the shaded sector is 575π/9 square units.
The area of the unshaded sector is 325π/9 square units
What is the area of the sectors?
The value of the angle subtended by the unshaded sector is 130⁰ the value of the angle subtended by the shaded sector is 230⁰.
To find the area of a sector with radius 10 units and angle 230⁰, we can again use the same formula:
Area of sector = (angle/360) x πr^2
Substituting the values given in the formula, we get:
Area of sector = (230/360) x π(10)²

cos² (x)(1+tan²(x)) = 1, establish the identity
Answer:
see below.
Step-by-step explanation:
Use Trigonometric Expansion.
Verify the following identity:
[tex]cos(x)^2(tan(x)^2+1)=1[/tex]
Write tangent as [tex]\frac{sine}{cosine}[/tex]
[tex]cos(x)^2(\frac{sin(x)}{cos(x)} ^2+1)=1[/tex]
[tex]cos(x)^2(\frac{sin(x)}{cos(x)} ^2+1)=cos(x)^2(\frac{sin(x)^2}{cos(x)^2+1} )[/tex]
[tex](cos(x)^2(\frac{sin(x)^2}{cos(x)^2} +1))=1[/tex]
Put sin(x)^2/cos(x)^2 +1 over the common denominator cos(x)^2 : sin(x)^2/cos(x)^2+1 = cos(x)^2+sin(x)^2 /cos (x)^2:
cos(x)^2(cos(x)^2+sin(x)^2/cos(x)^2)=1
Cancel cos(x)^2 from the numerator to the denominator.
cos(x)^2(cos(x)^sin(x)^2)/cos(x)^2=cos(x)^2(cos(x)^2+sin(x)^2)/cos(x)^2=cos(x)+sin(x)^2:
(cos(x)^2+sin(x)^2=1
Substitute cos(x)^2 + sin (x)^2 = 1:
1 =1

A parabola opening up or down has vertex (0, -4) and passes through (10, 1). Write its
equation in vertex form.
Answer:
Since the vertex is (0, -4), we know that the equation of the parabola will have the form:
y = a(x - 0)^2 - 4
where "a" is the coefficient that determines whether the parabola opens up or down.
To find the value of "a", we can use the fact that the parabola passes through the point (10, 1):
1 = a(10 - 0)^2 - 4
1 + 4 = 100a
5 = 100a
a = 1/20
Substituting this value of "a" into the equation for the vertex form, we get:
y = (1/20)x^2 - 4
So the equation of the parabola in vertex form is y = (1/20)x^2 - 4, with vertex (0, -4) and passing through (10, 1).
