Answer:

$4,723.21​

Step-by-step explanation:

Formula for COMPOUND INTEREST:

A = P ( 1 + r/n) ^ nt

Where A = principal money + interest earned,

P = Principal Money

r = interest rate in decmial

n = no. of times i.rate is compounded

nt = time

Since the qns asked to be compounded /monthly', you have the following formula:

A = 3250 ( 1 + 7.5%/12) ^ 60

7.5% is a yearly rate so divide it by 12 (as in 12 months)

60 = 5 years x 12 months

so use a calculator and you'll get $4723.206, round off and it's $4723.21

To find out how much Connie's investment in a savings account with a 7.5% annual interest rate compounded monthly will be worth in five years, use the compound interest formula. After calculations, her investment will be worth $4,723.21 in five years.

The student asks about the future value of an investment made in a savings account with compound interest. To calculate the amount Connie's investment will be worth in five years, we can use the compound interest formula, which is A = P(1 + r/n)^(nt). Here, P is the principal amount ($3,250), r is the annual interest rate (7.5% or 0.075 as a decimal), n is the number of times the interest is compounded per year (12, since it's monthly), and t is the number of years (5).

Using these values, we calculate the future value (A) as follows:

Convert the percent interest to a decimal: 7.5% = 0.075.

Divide the annual rate by the number of compounding periods: 0.075/12.

Add 1 to the interest rate per period: 1 + (0.075/12).

Calculate (1 + (0.075/12)) raised to the power of the total number of compounding periods: (1 + (0.075/12))^(12*5).

Multiply the principal by this amount: $3,250 × (1 + (0.075/12))^(12*5).

Connie's investment will grow to $$4,723.21 after five years, using compound interest.

Answer:

128

Step-by-step explanation:

To create 128 different hamburgers with multiple combinations of condiments, you would need 7 different condiments. This is due to the fact that each condiment presents 2 possibilities, on the burger or not, and 2 to the power of 7 equals 128.

In this scenario, each condiment represents an option that can be either included or excluded. This means that, for each condiment, there are 2 possibilities (it's either on the burger, or it's not). The question implies that the number of possible combinations equals 128, which is 2 to the power of 7.

So, to create 128 different hamburgers, the restaurant must offer 7 different condiments. This is because 2 (possibilities for each condiment) to the power of 7 (condiments) equals 128.

2) [tex]m=50\degree[/tex]

3) [tex]h=79\degree[/tex]

4) [tex]g=101\degree[/tex]

5) [tex]i=51\degree[/tex]

6) [tex]j=130\degree[/tex]

Explanation

From the diagram,

[tex]b=101\degree[/tex], corresponding angles are equal.

From the diagram, m=k, corresponding angles are equal.

But k+130=180, angles on a straight line sum up to 180 degrees.

This implies that k=180-130=50

[tex]\therefore m=50\degree[/tex]

From the diagram ; [tex]h+101=180\degree[/tex],angles on a straight line sum up to 180 degrees.

[tex]\implies h=180-101\degree[/tex]

[tex]\implies h=79\degree[/tex]

From the diagram, [tex]g=101\degree[/tex] vertically opposite angles are equal.

From the triangular portion;

i+h+m=180. sum of interior angles of a triangle.

This implies that:

i+79+50=180

i+129=180

i=180-129

[tex]i=51\degree[/tex]

Finally

[tex]j=130\degree[/tex], vertically opposite angles are equal.

Answer:

Part 1) ∠b=101°

Part 2) ∠m=50°

Part 3) ∠h=79°

Part 4) ∠g=101°

Part 5) ∠i=51°

Part 6) ∠j=130°

Step-by-step explanation:

Part 1) ∠b

we know that

∠b=101° ------> by corresponding angles

Part 2) ∠m

we know that

∠m=∠k ------> by corresponding angles

and

∠k+130°=180° -----> by supplementary angles

∠k=180°-130°=50°

therefore

∠m=50°

Part 3) ∠h

we know that

∠h+101°=180° -----> by supplementary angles

∠h=180°-101°=79°

Part 4) ∠g

we know that

∠g=101° -----> by vertical angles

Part 5) ∠i

we know that

The sum of internal angles of a triangle must be equal to 180 degrees

so

∠h+∠m+∠i=180°

substitute the values and solve for ∠i

79°+50°+∠i=180°

∠i=180°-129°=51°

Part 6) ∠j

we know that

∠j=130° -----> by vertical angles

To solve for F in terms of K, you can use the equation F = (9/5)(K) - 459.67.

To solve for F in terms of K, we need to isolate F on one side of the equation.

Step 1: Start with the given equation:

K = (5/9)(F + 459.67)

Step 2: Multiply both sides of the equation by 9/5 to undo the multiplication on the right side:

(9/5)(K) = F + 459.67

Step 3: Simplify the left side:

(9/5)(K) = F + 459.67

Step 4: Subtract 459.67 from both sides to isolate F:

(9/5)(K) - 459.67 = F

Therefore, F in terms of K is given by the equation F = (9/5)(K) - 459.67.

The width of the border around the stained glass window is approximately 1.15 feet, calculated by subtracting the stained glass area from the total area including the border.

To find the width of the border, we need to subtract the area of the stained glass window from the total area including the border.

Given:

- Length of stained glass window = 4 feet

- Width of stained glass window = 2 feet

- Area of stained glass window = [tex]\(4 \times 2 = 8\)[/tex] square feet

- Total area including the border = Area of stained glass window + Area of border = 8 + 7 = 15 square feet

Let's denote the width of the border as x feet.

The total length including the border is 4 + 2x feet, and the total width including the border is 2 + 2x feet.

The area of the total window with the border is the product of its length and width:

(4 + 2x)(2 + 2x) = 15

Expanding this equation:

8 + 4x + 4x + 4x^2 = 15

8 + 8x + 4x^2 = 15

4x^2 + 8x - 7 = 0

Now, let's solve this quadratic equation using the quadratic formula:

[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]

Where a = 4, b = 8, and c = -7.

[tex]\[x = \frac{{-8 \pm \sqrt{{8^2 - 4 \times 4 \times (-7)}}}}{{2 \times 4}}\][/tex]

[tex]\[x = \frac{{-8 \pm \sqrt{{64 + 112}}}}{8}\][/tex]

[tex]\[x = \frac{{-8 \pm \sqrt{{176}}}}{8}\][/tex]

[tex]\[x = \frac{{-8 \pm 4\sqrt{{11}}}}{8}\][/tex]

[tex]\[x = \frac{{-2 \pm \sqrt{{11}}}}{2}\][/tex]

Since the width cannot be negative, we take the positive root:

[tex]\[x = \frac{{-2 + \sqrt{{11}}}}{2} \approx 1.15 \text{ feet}\][/tex]

Therefore, the width of the border is approximately 1.15 feet.

Apply formula:

[tex]\tan\left(\theta\right)=\frac{opposite}{adjacent}[/tex]

[tex]\tan\left(B\right)=\frac{AC}{BC}[/tex]

[tex]\tan\left(30^o\right)=\frac{AC}{11}[/tex]

a)zw  = 44.295 cos(1.924) +isin(1.924))

b) z/w= 4.921 cos(-0.936) + isin(-0.936)

Step-by-step explanation:

Given:

z=13+7i

w=3(cos(1.43)+isin(1.43)  

a. convert zw using De Moivre's theorem  

First coverting z into  polar form:

13^2 + 7^2  = 14.765

[tex]\sqrt{14.765}[/tex] =r

θ= arctan (7/13)

 = 0.49394                            (28.301 in degrees)

z= 14.765(cos(0.49394)+isin(0.49394)  )

Now finding zw

zw= 14.765(cos(.494)+isin(.494))×3(cos(1.43)+isin(1.43))

Using De Moivre's theorem, the modulus will be multiplied

14.765 x 3=44.295

whereas the angles will be added

.494+1.43=1.924

Thus:

zw  = 44.295 cos(1.924) +isin(1.924))

b)

finding z/w

z/w= 14.765(cos(.494)+isin(.494)) / 3(cos(1.43)+isin(1.43))

Using De Moivre's theorem, the modulus will be divided

14.765 / 3 = 4.921

whereas the angles will be subtracted:

.494-1.43=-0.936

Thus:

z/w= 4.921 cos(-0.936) + isin(-0.936) !

To calculate the likelihood of drawing cards 5 and 6 in sequence from a shuffled deck of 8 cards, we multiply the individual probabilities of drawing each card. The result is a probability of 1/56.

The question asked is a probability question which involves finding the likelihood of drawing two specific cards in sequence from a shuffled deck. However, the detailed information provided relates to different scenarios involving card colors numbered cards, and rolling dice. It does not directly provide the information needed for calculating the specific probability of selecting cards 5 and 6 from a stack of 8 cards numbered 1-8. Nonetheless, if we base our calculation on a standard probabilistic approach without considering the provided scenarios:

The probability of selecting the card number 5 first from the stack of 8 is 1/8 since there is one card number 5 out of eight total cards. Once card number 5 has been selected, it is no longer in the stack, so there are now seven cards left. The probability of selecting card number 6 after that is 1/7. Therefore, the probability of selecting card 5 and then card 6 in the sequence is the product of the two probabilities: 1/8 * 1/7 = 1/56.
