What is the area of the rhombus shown below?
EG = 20
FD = 15​

Amount obtained in Compound interest is given by :

[tex]\bigstar\;\;\boxed{\mathsf{Amount = Principal\bigg(1 + \dfrac{Rate\;of \;interest}{100}\bigg)^{Conversion\;periods}}}[/tex]

Note : Conversion period is the time from one interest period to the next interest period. If the interest is compounded annually then there is one conversion period in an year. If the interest is compounded semi-annually then there are two conversion periods in an year. if the interest is compounded quarterly then there are four conversion periods in an year.

Problem :

Given : $500 is invested for one year at 4% annual interest

[tex]\implies\boxed{\begin{minipage}{4 cm}\bigstar\;\;\textsf{Principal = 500}\\\\\bigstar\;\;\textsf{Time period = 1 year}\\\\\bigstar\;\;\textsf{Rate of interest = 4\%}\end{minipage}}[/tex]

As the question mentions the term ''compounded quarterly'', there are 4 conversion periods in a year.

If the interest is compounded quarterly, then the rate of interest per conversion period (quarter) will be :

[tex]\implies \mathsf{\left(\dfrac{1}{4} \times 4\%\right) = 1\%}[/tex]

Substituting all the values in the Amount formula of C.I, We get :

[tex]\mathsf{\implies Amount = 500\bigg(1 + \dfrac{1}{100}\bigg)^4}[/tex]

[tex]\mathsf{\implies Amount = 500\left(1 + 0.01\right)^4}[/tex]

[tex]\mathsf{\implies Amount = 500\left(1.01\right)^4}[/tex]

[tex]\mathsf{\implies Amount = 520.30}[/tex]

We know that : Interest = Amount - Principal

[tex]:\implies[/tex]  Interest = 520.30 - 500

[tex]:\implies[/tex]  Interest = $20.30

If $500 is invested in a savings account with a 4% annual interest rate compounded quarterly for one year, it would earn $20.04 in interest.

To calculate the interest earned on a savings account, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount (initial investment), r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, the principal amount is $500, the annual interest rate is 4% (or 0.04 as a decimal), the interest is compounded quarterly (so n = 4), and the investment period is one year (so t = 1).

Plugging the values into the formula, we get:

A = 500(1 + 0.04/4)^(4×1)

Simplifying the equation, we calculate that the final amount after one year is $520.04. To find the amount of interest earned, we subtract the initial investment ($500) from the final amount ($520.04):

Interest = $520.04 - $500 = $20.04.

Therefore, $500 would earn $20.04 in interest if invested for one year in a savings account with a 4% annual interest rate compounded quarterly.

Answer:

-sqrt(3)/2

Step-by-step explanation:

Use double angle identity for sin(2x)

sin(2x)=2sin(x)cos(x)

We are given sin(x)=-1/2 so we already have so far that:

sin(2x)=2(-1/2)cos(x)

sin(2x)=-1*cos(x)

We just need to find cos(x).  

x is in the fourth quadrant so cosine will be positive there

knowing the unit circle we should know that if sin(x)=-1/2 then cos(x)=sqrt(3)/2 while in 4th quadrant.

So the answer is sin(2x)=-1*sqrt(3)/2=-sqrt(3)/2

Answer: Yes.

Step-by-step explanation:

30/5 or 30 divided by 5 simplifies to 6. 6 is a whole number and therefore it is an integer.

The given options are 1) y = (cos x) / x is neither and 2) y = (sin x) / x is even.

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right-angled (not of 90 degrees).

The slanted side is called the hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.

1) y = (cos x) / x is neither, since cos x is even and x is odd.  

2) y = (sin x) / x is even since sin x and x would either both be positive at the same time or negative at the same time.  

We know that (-) / (-) is positive, just as (+) / (+) is positive.

Final answer:

1. The function y=cos(x)/x is neither even nor odd due to its lack of symmetry properties

2. y=sin(x)/x is an odd function as it satisfies the symmetry condition about the origin.

Explanation:

To determine if the functions y=cos(x)/x and y=sin(x)/x are even, odd, or neither, we need to understand the definitions of even and odd functions and apply them accordingly.

Even and Odd Functions:

An even function satisfies the condition f(-x) = f(x), meaning the function's graph is symmetric about the y-axis. An odd function satisfies the condition f(-x) = -f(x), indicating symmetry about the origin.

Analysis of y=cos(x)/x:

To determine if y=cos(x)/x is even, odd, or neither, replace x with -x:

y=cos(-x)/(-x) = cos(x)/(-x) because cos(-x) = cos(x), an even function property.

This contradicts the definitions of both even and odd functions; hence, y=cos(x)/x is neither even nor odd.

Analysis of y=sin(x)/x:

Similarly, for y=sin(x)/x, replace x with -x:

y=sin(-x)/(-x) = -sin(x)/(-x) because sin(-x) = -sin(x), an odd function property.

This simplifies to y=sin(x)/x, which satisfies the condition for an odd function.

Therefore, y=sin(x)/x is an odd function.

Answer:

See below in BOLD.

Step-by-step explanation:

What you need to do is identify the corresponding sides in the polygon than divide the larger length by the smaller.

3.  The side length 8 corresponds to the 4 in the other polygon.

So the scale factor  is 8/4 = 2.

4. Scale Factor = 24/20 = 1.2.

5. 40/32  = 5x / 24

5x = 40*24 / 32

5x = 30

x = 6.

6. 25/30 = 4x + 7 / 42

5/6 = 4x + 7 / 42

6(4x + 7) = 210

24x = 210 - 42 = 168

x = 168/24

x = 7.

7. 40/24 = 3x + 5 / 21

5/3 = (3x + 5) / 21

9x + 15 = 105

9x = 90

x = 10.

8.   24 / 40 = (x + 3) / 15

3/5 = (x + 3) / 15

5x + 15 = 45

5x = 30

x = 6.

Answer:

Just add up the measurements of the sides and then double the result.

(2 + √5 + 6 + 3√5) · 2

= (8 + 4√5) · 2

= 16 + 8√5 (cm)

To answer your question, we first need to understand that the perimeter of a rectangle is calculated by adding up all its sides or simply twice the sum of its length and width.

From the information given, the width of the rectangle is equal to 2 cm plus the square root of 5 cm, while the length is 6 cm plus 3 times the square root of 5 cm.

So now, let's sum up the length and the width:
= (2 + √5 cm) + (6 + 3√5 cm)
= 8 + 4√5 cm

We then multiply this result by 2 (to account for both sets of opposite sides of the rectangle):
Perimeter = 2 * (8 + 4√5 cm)
Perimeter ≈ 33.89 cm

Therefore, the perimeter of the rectangle is roughly 33.89 cm.

Answer:

Circles A  and D are congruent because they both have a radius of 3

Step-by-step explanation:

Answer:

Circle A and circle D are congruent ⇒ 3rd answer

Step-by-step explanation:

* Lets talk about the circle

- Any circle has diameter

- Any circle has radius which is half the diameter in length

- All the circles are similar because the measure of all circles is 360°

 and there is the ratio between the radii

- The two circles are congruent if they have the same radii because

  the congruence is special case of similarity when the ratio equal 1

* Lets look to the figure to solve the problem

- There are four circles in the figure

# Circle A with radius 3"

# Circle B with radius 4"

# Circle C with radius 5"

# Circle D with radius 3"

∵ The radius of circle A = 3"

∵ The radius of circle D = 3"

∴ The radii of circle A and circle D are congruent

∴ Circle A and circle D are congruent

I believe the correct answer is 0

Step-by-step explanation:

To solve this question, we use an abbreviation formula called BODMAS which is:

B = Brackets

O = Of

D = Division

M = Multiplication

A = Addition

S = Subtraction

We solve each element that is available in the order of the abbreviated letter.

1. We solve the brackets:

[tex](5\times12) = 60[/tex]

2. We solve the second bracket:

[tex](60\div3) = 20[/tex]

The equation now is [tex]20+30-50[/tex]

3. We now solve addition first:

[tex]20+30=50[/tex]

4. Now we solve the subtraction:

[tex]50-50=0[/tex]

The answer then = 0

B-Bracket

O-of

D-Division

M-Multiplication

A-Addition

S-Subtraction

[tex]\bigg(\displaystyle\frac{(5\times 12)}{3}\bigg)+30-50\\\\=\bigg(\displaystyle\frac{60}{3}\bigg)+30-50\\\\=20+30-50\\\\=50-50\\\\=0[/tex]

The value of expression is 0.

notice that all you do is simply multiply the terms of either one by the terms of the other sequentially, then add like-terms.

For this case we have the following expression:

[tex](-4x) ^ 2 = 100[/tex]

To look for the solution:

 We apply root to both sides of the equation to eliminate the exponent:

[tex]-4x = \pm \sqrt {100}\\-4x = \pm10[/tex]

Then we have two solutions:

[tex]-4x = 10[/tex]

Dividing between -4 on both sides of the equation:

[tex]x = \frac {10} {- 4}\\x = - \frac {5} {2}[/tex]

The second solution:

[tex]-4x = -10[/tex]

Dividing between -4 on both sides of the equation:

[tex]x = \frac {-10} {- 4}\\x = \frac {5} {2}[/tex]

Answer:

[tex]x_ {1} = - \frac {5} {2}\\x_ {2} = \frac {5} {2}[/tex]

Step-by-step explanation:

* Let revise how to find the vertical asymptote

- Vertical asymptotes of a rational function f(x)/g(x) can be found by

 solving the equation g(x) = 0 ⇒ the denominator of the fraction

- Note: this only applies if the numerator f(x) is not zero for the same

 x value

* Lets solve the problem

∵ F(x) = 1/x(x + 6)(x - 1)

∵ The denominator of the fraction is x(x + 6)(x - 1)

- To find the equation of the vertical asymptote Put the

 denominator = 0

∴ x(x + 6)(x - 1) = 0

- The denominator has three factors, equate each by 0

∴ x = 0

OR

∴ x + 6 = 0 ⇒ subtract 6 from both sides

∴ x = -6

OR

x - 1 = 0 ⇒ add 1 to both sides

∴ x = 1

∴ From all above there are 3 vertical asymptotes at x = -6 , 0 , 1
