The annual percentage yield (APY) of Russ is 4.39 %
What is Annual Percentage Yield?
The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest.
Given data ,
Deposit amount of Russ = $ 4500
Interest rate R = 4.3 %
And it is given that the interest rate is compounded daily , so
Interest rate R = 4.3 % / 365
= 0.043 / 365
= 0.0001178
Now , The annual percentage yield (APY) is calculated as
The interest amount = 4500 x ( 1 + 0.0001178 )³⁶⁵
= 4500 x ( 1.0001178 )³⁶⁵
= 4500 x 1.04393211
= 4697.694
≈ 4697.69
Therefore , the interest will be
= 4697.69 - 4500
= $ 197.69
Now , the annual percentage yield (APY) is given by
= Interest / Deposit
= 197.69 / 4500
= 0.0439
≈ 4.39 %
Hence , annual percentage yield (APY) of Russ is 4.39 %

As Mars revolves around the sun, it travels at a speed of approximately 15 miles per second. Convert this speed to kilometers per second. At this speed, how
many kilometers will Mars travel in 20 seconds? In your computations, assume that I mile is equal to 1.6 kilometers. Do not round your answers.
Mars travels at a rate of 24 km per second.
At this rate, Mars travel 480 km in 20 seconds.
What is speed?
The speed of an item, which is a scalar quantity in everyday usage and kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time.
Here, we have
Mars revolves around the sun, it travels at a rate of approximately 15 miles per second.
1 mile = 1.6 km (given)
15 miles = 15 ×1.6 = 24 km
So, Mars travels at a rate of 24 km per second.
In 20 seconds, Mars will travel 24×20 =480km
Hence, Mars travels at a rate of 24 km per second.

The temperature T, in degrees Fahrenheit, t hours after 6 AM is given by:
T(t)= -1/2t^2+8t+32
0≤1≤ 12
What is the warmest temperature of the day? When does this happen?
The warmest temperature or "maximum" temperature means we need to find the derivative of the function.
T = -(t^2)/2 + 8t + 32
dT/dt = -t +8
A maximum/minimum occurs when the derivate(gradient) = 0
Therefore, dT/dt = 0
0 = -t + 8
t = 8
Putting t = 8 back into the original equation gives.
T(8) = 64 degF
So the warmest temperature is 64 degF 8 hours after 6am so at 2pm

What is a ratio?A ratio in mathematics displays the multiplicative relationship between two numbers. In a bowl of fruit, for instance, the proportion of oranges to lemons is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). In a similar vein, the proportion of oranges to the overall amount of fruit is 8:14, while that of lemons to oranges is 6:8 (or 3:4). (or 4:7).
A ratio can include any number of numbers as its components, including counts of people or things, weights, lengths, and times, among other values. Both numbers must be positive in the majority of situations.
Given, the covering land is 5(3/8) acres
That is 43/8 acres
By dividing the plots as 3/4 each, we get
(43/8)*(4/3)=43/6=7.1666

One of your friends missed the class on scientific notation. Describe how you would explain to your friend what it means for a number to be in scientific notation and how to convert a number from standard form to scientific notation.
Using the concept of scientific notation we can write 5.14*10^5 to convert from 5.14*10^5.
What is scientific notation?
Using scientific notation, one can express extremely big or extremely small values.
When a number between 1 and 10 is multiplied by a power of 10, the result is represented in scientific notation.
For instance, 650,000,000 can be represented as 6.5 108 in scientific notation.
The scientific notation consists of a coefficient multiplied by 10 and raised to an exponent.
To convert to a real number, start with the base and multiply by 5 tens like this: 5.14 × 10 × 10 × 10 × 10 × 10 = 514000(there are only 4 zeros because you cancel one zero to remove the decimal) so we write 5.14*10^5 to convert from 5.14*10^5.

Use the dot plot to complete the statements. The dot plot shows that Amelie swam 3 laps times. Amelie most frequently swam laps. The data distribution is .
Regarding the data-set, we have that:
The dot plot shows that Amelie swam 3 laps two times.Amelie most frequently swam 5 laps.The data distribution is left skewed.What is shown by the dot plot?The dot plot shows the absolute frequencies of each observation, hence we have that:
Amelie swam two laps three times.Amelie swam three laps two times.Amelie swam four laps three times.Amelie swam five laps five times. -> most frequent due to the highest number of dots.Amelie swam six laps four times.Amelie swam seven laps two times.Amelie swam ten laps one time.The distribution is analyzed considering the mean and the median.
The mean is given by the sum of all observations divided by the number of observations, hence:
Mean = (2 x 3 + 3 x 2 + 4 x 3 + 5 x 5 + 6 x 4 + 7 x 2 + 10 x 1)/(3 + 2 + 3 + 5 + 4 + 2 + 1) = 4.85.
There are 20 observations, hence the median is composed by the mean of the 10th and of the 11 observation, which are both of five, hence the median is of five.
Since the median is greater than the median, the data distribution is left skewed.

Yes, the answers are same from both the expressions i.e. 133.
Given, an expression i.e. 4(3a + 7) + 3(2a + 5)
Now, we are asked to find an equivalent expression for the given expression.
So, on simplifying the given expression, we get
4(3a + 7) + 3(2a + 5)
12a + 28 + 6a + 15
12a + 6a + 28 + 15
18a + 43
So, (18a + 43) is an equivalent expression for the given expression i.e.
4(3a + 7) + 3(2a + 5)
Now, On putting the value of a = 5 in both the expressions, we get
4(3(5) + 7) + 3(2(5) + 5)
= 4(15 + 7) + 3(10 + 5)
= 4(22) + 3(15)
= 88 + 45
= 133
also in (18a + 43),
= 18(5) + 43
= 90 + 43
= 133.
Hence, (18a + 43) is an equivalent expression for the given expression i.e.
4(3a + 7) + 3(2a + 5).
Yes, the answers are same from both the expressions i.e. 133.

Answer:
1. A
2. A, B, D
Step-by-step explanation:
The first one is pretty straightforward, divide 7^2 to both the denominator and numerator, so you get 1/7^2. 7^2 is 49, which is not 14, so A is false. Everything else produces 1/49 in some shape or form.
The second question is also relatively easy. A is correct because 1/4 is 4^-1 and (4^-1)^-1 is 4^1. B is also right because if you add all the exponents up, you basically get -5+6+1=2, and 2^2 is 4. C is wrong because (1/2)^2 is 1/4, not 4. D is correct because 2^(5-3) is 2^2, which is 4. E is wrong because 4^(4-2) is 4^2, which is 16, not 4.
Overall, it's not hard, nor does it take time, you just need to remember the basic formulas: [tex]\frac{1}{x^a} =x^{-a[/tex], [tex]x^a * x^b=x^{a+b[/tex], and [tex]\frac{x^a}{x^b} = x^{a-b[/tex]
