Sienna Rose received $4000 cash in graduation presents. She invests it in an account earning 3.60% interest compounded monthly. How long will it take for her money to grow to $7000?
Answers
Answer:
About 16 years
Step-by-step explanation:
The formula for compound interest is
\(P(t)=P_{0}(1+r/n)^n^t\), where P0 is the principal, r is the interest rate, n is the number of compounding periods, and t is the time in years.
For this problem, our n = 12 because there are 12 months in a single year and we must convert our percentage to a decimal (3.60/100 = 0.0360): \(7000=4000(1+0.0360/12)^1^2^t\\7000=4000(1.003)^1^2^t\\1.75=1.003^1^2^t\\log(1.75)=log(1.003)^1^2^t\\log(1.75)=12t*log(1.003)\\\frac{log(1.75)}{log(1.003)} =12t\\1/12*\frac{log(1.75)}{log(1.003)}=t\\ 15.56818868=16=t\)
When you code a SELECT statement, you must code the four main clauses in the following order
SELECT, WHERE, ORDER BY, FROM
SELECT, ORDER BY, FROM, WHERE
SELECT, FROM, WHERE, ORDER BY
SELECT, FROM, ORDER BY, WHERE
Answers
When coding a SELECT statement in SQL, it is crucial to follow a specific order for the four main clauses to ensure accurate and efficient retrieval of data. The correct order to code the clauses is c. SELECT, FROM, WHERE, ORDER BY.
Firstly, the SELECT clause specifies the columns that you want to retrieve data from. This clause is always coded at the beginning of the statement. Next, the FROM clause identifies the table or tables from which you want to retrieve data. It is important to note that the tables in the FROM clause must be listed before the WHERE clause.
The WHERE clause is used to filter the data based on certain criteria or conditions. This clause is typically coded after the FROM clause. Lastly, the ORDER BY clause sorts the retrieved data in ascending or descending order based on a specified column. This clause is always coded at the end of the statement.
Therefore, the correct order for coding the four main clauses in a SELECT statement is SELECT, FROM, WHERE, and ORDER BY. By following this order, you can ensure that your query runs smoothly and returns the correct results.

suppose a jar contains 19 red marbles and 25 blue marbles. if you reach in the jar and pull out 2 marbles at random, find the probability that both are red. write your answer as a reduced fraction.
Answers
The probability that both marbles are red is 9/23.
To find the probability of both marbles being red, follow these steps:
1. Calculate the total number of marbles in the jar: 19 red + 25 blue = 44 marbles.
2. Determine the probability of picking a red marble on the first draw: 19 red marbles / 44 total marbles = 19/44.
3. After picking one red marble, there are 18 red marbles and 43 total marbles left. Calculate the probability of picking a red marble on the second draw: 18 red marbles / 43 total marbles = 18/43.
4. Multiply the probabilities from steps 2 and 3 to find the overall probability: (19/44) x (18/43) = 342/1892.
5. Simplify the fraction: 342/1892 = 9/23.

Please do and explain numbers 2, 4, 6, and 8, thank you.
Answers
Answer:
2. w = -3
4. c = -2
6. r = 7
8. n = 4
Step-by-step explanation:
It's hard to read the photo, but I'll try.
2.
\( 2^{w + 4} \times 2^{4w + 6} = 2^{2w + 1} \)
On the left side, you have a product of 2 powers with the same base.
Give the same base and add the exponents, as in the rule
\( a^m \times a^n = a^{m + n} \)
You get on the left side 2 to the sum of the exponents.
\( 2^{w + 4 + 4w + 6} = 2^{2w + 1} \)
Simplify the long exponent on the left side.
\( 2^{5w + 10} = 2^{2w + 1} \)
Now we have another rule we can use. If two powers are equal, and their bases are equal, then the exponents must be equal.
Here, 2 to the power 5w + 10 equals 2 to the power 2w + 1. Since both bases are 2 and are equal, then the exponents must be equal.
5w + 10 = 2w + 1
Subtract 2w from both sides. Subtract 10 from both sides.
3w = -9
Divide both sides by 3.
w = -3
4.
\( \dfrac{1}{5} = 5^{2c + 3} \)
We need to write the left side as a power of 5. Then we equate the exponents like we did in problem 2.
Recall the rule:
\( a^{-n} = \dfrac{1}{n} \)
Apply this rule to the left side in reverse.
\( 5^{-1} = 5^{2c + 3} \)
Now we have two powers that are equal, both having the same base, 5, so the exponents must be equal.
2c + 3 = -1
2c = -4
c = -2
6.
\( 216 = 6^{2r - 11} \)
This is the same idea as problem 4. Write the left side as a power of 6.
\( 6^3 = 6^{2r - 11} \)
\( 2r - 11 = 3 \)
\( 2r = 14 \)
\( r = 7 \)
r = 7
8.
\( 4^{n} \times 4^{2n - 9} = 64 \)
This problem is similar to problem 2.
\( 4^{n + 2n - 9} = 4^3 \)
\( 4^{3n - 9} = 4^3 \)
3n - 9 = 3
3n = 12
n = 4

Winte the equation of the lane tangent to the graph of the function at the indicated point. As a check, graph both the function and the tangent line you found to see whether it looks correct. y= √5x^2-1 dx=1.
Answers
The equation of the tangent line to the graph of the function y = √(5x^2 - 1) at the point where x = 1 is y = (5/2)x - (5/2) + 2√2.
To find the equation of the tangent line to the graph of the function y = √(5x^2 - 1) at the point where x = 1, we need to follow these steps:
Find the derivative of the function y = √(5x^2 - 1) with respect to x.
y' = (1/2) * (5x^2 - 1)^(-1/2) * 10x
= 5x / √(5x^2 - 1)
Evaluate the derivative at x = 1 to find the slope of the tangent line at that point.
y'(1) = 5(1) / √(5(1)^2 - 1)
= 5 / 2
Use the point-slope form of the equation of a line to find the equation of the tangent line.
y - y1 = m(x - x1)
where (x1, y1) is the point on the graph where x = 1 and m is the slope we just found.
Substituting x1 = 1, y1 = √(5(1)^2 - 1) = 2√2 - 1, and m = 5/2, we get:
y - (2√2 - 1) = (5/2)(x - 1)
Simplifying this equation, we have:
y = (5/2)x - (5/2) + 2√2
Therefore, the equation of the tangent line to the graph of the function y = √(5x^2 - 1) at the point where x = 1 is y = (5/2)x - (5/2) + 2√2.
To check whether this looks correct, we can graph the function and the tangent line using a graphing calculator or software. The graph should show the curve of the function and the straight line of the tangent intersecting at the point where x = 1.

Answers
Answer:
RE = 61
Step-by-step explanation:
the sides of a square are congruent , then
SQ = QR , that is
6x - 5 = 2x + 39 ( subtract 2x from both sides )
4x - 5 = 39 ( add 5 to both sides )
4x = 44 ( divide both sides by 4 )
x = 11

Kira studied data collected on the school basketball team for one season. She noticed that a player on the team had 13 successful free throws out of a total of 20 attempted free throws. To find the percentage of the total free throws attempted by this player that were successful, Kira set up the equivalent ratios below?
13/20 = m/n
Answers
Step-by-step explanation:
To find the equivalent ratio for 13/20 in terms of m/n, we can set up the proportion:
13/20 = m/n
To solve for m/n, we can cross-multiply:
13n = 20m
Then, we can divide both sides by 13 to isolate m/n:
m/n = 20/13
So, the equivalent ratio for 13/20 in terms of m/n is 20/13.
Step-by-step explanation:
so, to find the % of successful free throws out of the total number of free throws, we only need to do the division as indicated by the ratio :
13/20 = 0.65
so, 0.65 parts of of the whole 1 were successful.
as % is expressed in parts of 100, we need to multiply this statement by 100 :
65 parts of the whole 100 were successful.
so, 65% were successful.
Herschel uses an app on his smartphone to keep track of his daily calories from meals. One day his calories from breakfast were 115 more, than his calories from lunch, and his calories from dinner were 200 less than twice his calories from lunch. If his total caloric intake from meals was 2135, determine his calories for each meal.
Answers
Answer:
calories
Breakfast: 670
Lunch: 555
Dinner: 910
Total = 2135 calories
Step-by-step explanation:
Let B, L and D, stand for the calories from Breakfast, Lunch, and Dinner
One day his calories from breakfast were 115 more, than his calories from lunch:
B = L + 115
his calories from dinner were 200 less than twice his calories from lunch.:
D = 2L - 200
total caloric intake from meals was 2135:
B + L + D = 2135
------
We have B and D defined in terms of L from the first two equations, so use them in the third:
B + L + D = 2135
[L+115] + L + [2L-200] = 2135
4L - 85 = 2135
4L = 2220
L = 555 calories
B = L + 115
B = 555 + 115
B = 670 calories
D = 2L - 200
D = 2(555) - 200
D = 910 calories
================
CHECK
Does B + L + D = 2135 calories?
670 + 555 + 910 = 2135?
2135 = 2135? YES

Rainwater is accumulating at a rate of 1.55 centimeters per hour, cmh. What is the rate of rain accumulation in millimeters per hour, mmh
Answers
To convert centimeters per hour, cmh, to millimeters per hour, mmh, we need to multiply by a conversion factor of 10.
1 centimeter = 10 millimeters
1 hour = 60 minutes
Therefore, 1 centimeter per hour is equal to 10/60 or 0.1667 millimeters per minute.
To convert this to millimeters per hour, we need to multiply by 60:
0.1667 mm/min x 60 min = 10 mm/hour
Thus, the rate of rain accumulation in millimeters per hour is 1.55 cm/hour x 10 mm/cm = 15.5 mm/hour.
Therefore, the rate of rain accumulation in millimeters per hour, mmh is 15.5.
