Annual nominal rate compounded monthly has the account earned is 0.84% .
In the question ,
it is given that ,
An employee opened a credit union account ,
amount deposited each month (PMT) = $90
number of period (n) = 2 years = 24 months
Future value after 2 years (FV) = $2177.48
let the rate of interest compounded monthly has the account earned be "r"
we know that the future value formula is
Future Value = PMT× [tex](\frac{(1+\frac{r}{12})^{n} -1 }{\frac{r}{12} } )[/tex]
Substituting the value of n = 24 , PMT = 90 and FV = 2177.48 in the Future Value Formula ,
we get ,
2177.48 = 90 × [tex](\frac{(1+\frac{r}{12})^{24} -1 }{\frac{r}{12} } )[/tex]
[tex](\frac{(1+\frac{r}{12})^{24} -1 }{\frac{r}{12} } )[/tex] = 2177.48/90
( 1 + r/12 )²⁴ -1 = (r/12) × 24.194
Solving further , we get
r = 0.0084
that means rate is = 0.84%
Therefore , Annual nominal rate compounded monthly has the account earned is 0.84% .

Using the theories of quantitative variables, we got that Graphical display is the first thing that should be done when we are analyzing two quantitative variables.
Comparing the Two Quantitative Variables As we did when considering only one variable, we begin with the graphical display. A scatterplot is the most useful display technique for comparing the two quantitative variables. We plot on the y-axis the variable we consider for the response variable and on the x-axis we place the explanatory or the predictor variable.

147,21,3 Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
The sequence is geometric and the common ratio is 1/7
How to determine if the sequence is arithmetic or geometric?An arithmetic sequence is a sequence of numbers in which each differs from the preceding one by a constant value e.g 2, 4, 6, etc. That is: 6-4 = 4-2 = 2
A geometric sequence is a sequence of numbers with a constant ratio between each number and the one before e.g. 9, 27, 81, etc. That is: 81/27 = 27/9 = 3
Given: 147, 21, 3
This sequence does not have a common difference. Thus, it is not arithmetic
This sequence has a common ratio. Thus, it is geometric
common ratio = 21/147 = 1/7 or 3/21 = 1/7
Therefore, the sequence is geometric and has a common ratio of 1/7

Tomas drives 75 km at an average speed of 110 km/h and then 7 km at 40 km/h without stopping. What is the average speed for the whole journey to 1 dp?
The average speed for the whole journey is 95.3km/hour
What is average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.
Average speed = Total distance/total time taken
The distance covered in the first journey is 75km and the time spent is calculated as Distance/speed
= 75/110 = 0.68hour
The time used for the second journey is
= distance/speed
= 7/40 = 0.18 hour
The total time spent = 0.68+0.18 = 0.86 hour
The total distance traveled = 75+7 = 82km
Therefore the average speed = 82/0.86 = 95.3 km/hour.

Sales tax in bernie’s state is 7. 40%, and he will be responsible for a $795 vehicle registration fee and a $110 documentation fee. Bernie plans to trade in his existing car, a 1999 buick riviera in good condition, and finance the rest of the cost for five years at an interest rate of 12. 77%, compounded monthly. Assuming that the dealer gives bernie the listed trade-in price for his car, what will his monthly payment be? round all dollar values to the nearest cent.

If the dealer gives Bernie the listed trade- in price for his car, he will pay $391.97 monthly.
Given that,
Bernie has decided to purchase a new car of $ 18,575.
The sales tax is 7.40%
Now,
18,575 x 7.40% = 1,374.55
Now, summing up the result of sales tax and purchase price, we get,
18,575 + 1,374.55 = 19,949.55
Bernie will give registration fees of $795
and, a documentation fees: $110
Now , we will sum up all the above information, i.e.,
= 19,949.55 + 795 + 110
= 20,854.55
Now, divide the result of documentation fees and registration fees by 5
20,854.55 ÷ 5 = 4,170.91
Dividing the above result by 12,
4,170.91 ÷ 12 = 347.58
Now, the finance the rest of the cost for five years at an interest rate 12.77%.
347.58 x 12.77% = 44.39
And,
347.58 + 44.39 = 391.97

The values of m<4 and m<6 are 160° and 20° respectively
How to find the value of m<4 and m<6?
To solve this problem, we need some angle geometry knowledge:
Given that: m<6 = 1/8 m<4
Since m<6 = 1/8 m<4. Thus, m<4 = 8.m<6
m<6+ m<4 = m<6 + 8.m<6 = 9.m<6 (Algebra)
m<6+ 8.m<__ = 180° will be:
m<6+ 8.m<6 = 180°
Note: m<6 + m<5 = 180° (angles on a straight line) and m<5 = m<6 (alternate angles)
m<6+ 8.m<6 = 180°
9.m<6 = 180°
m<6 = 180/9 = 20°
m<4 = 8 x m<6
m<4 = 8 x 20° = 160°
Therefore, the values of m<4 = 160° and m<6 = 20°

betty can mow a lawn in 120 minutes. bullwinkle can mow the same lawn in 40 minutes. how long does it take for both betty and bullwinkle to mow the lawn if they are working together?
Using the Work time problem solving technic, Betty and Bullwinkle to mow the entire lawn in 30 minutes if they are working together.
As we know that if A is complete the work of z in x days and B is complete the same work (z) in y days then both of can do complete work together then Equation of both A and B are completing work (z) together in
( 1/x + 1/y = 1/z ) days
Since Betty can mow a lawn is 120 minutes, then
Betty's mowing rate is 1/120th of a lanw per minute.
Since Bullwinkle can mow a lawn is 40 minutes, then Bullwinkle mowing rate is 1/40th of a lawn per minute.
Suppose working together they can a lawn in x minutes.
both together they can mow a lawn is x minutes, then their combined mowing rate is 1/x th of a lawn per minute.
To get the equation,
the sum of their mowing rates must equal their combined mowing rate,
1/40 + 1/120 = 1/x
Solve that by multiplying through by LCD of 40 and 120 is 120 then 4x = 120 => x = 30
Hence, when both are working together they complete the work together in 30 minutes .

What is Transformation?In mathematics, the phrases translation, rotation, and reflection are all used to describe the change of forms. This refers to a form moving beyond a mirror line or a fixed point. While being translated, rotated, or reflected, the shape doesn't change. The constant rotation of a shape around a fixed point or across the mirror line is known as translation. Rotation defines the way a form moves about a central axis. Shapes can be rotated by a specific number of degrees either clockwise or counterclockwise.
The rule for translation of given figure will be,
We need to move x for 3 units to left and y for 4 units downwards to get the translation, so the rule is:
