The first time Account # 1: was 1 year
account number # 2: was 10 years
Now just double it. Need help asap, thank you!!
Answers
For investment account 1, the balance doubles every year, so to find the time it takes to double again, we would need to solve for the time when the balance becomes $400 (double the starting balance of $200).
For investment account 2, the balance increases by $100 each year, so to find the time it takes to double again, we would need to solve for the time when the balance becomes $2,000 (double the starting balance of $1,000).

Function f is represented by this table of values.
If f(x) is vertically stretched by a factor of 2 to obtain g(x), which table of values represents function g?
Answers
According to the table, the values of g(x) are 2 units lower than the corresponding values of f(x).
Translation of functions
When a function is transferred without undergoing any form or rotation changes, it has been "translated." A function may be translated both horizontally and vertically.
According to the question;
The table that illustrates function g(x) is; when the function f(x) is shifted vertically down by 2 units to obtain function g
x = 0, 1, 2, 3
g(x) = -2, 0, 6, 24
By shifting the function f vertically down by 2 units, the function g(x) is produced.
Note that the relationship between the functions g and f is as follows:
g(x) = f(x) -2
Therefore, as seen in the above table, the values of g(x) are 2 units fewer than the corresponding values of f(x).

Andrew put in 80 hours of work in July for which he is entitled to $920.65. He also works 5 hours overtime. If she receives a paycheck of $1030.45 for the month, how much is she paid for an hour of overtime work? Write an EQUATION and then solve it.
Answers
Answer: Let's call the hourly rate for regular work as "r" and the hourly rate for overtime work as "o".
From the information given, we know that 80 hours of regular work earned Andrew 80 * r = $920.65.
And we also know that 5 hours of overtime work earned him 5 * o = $109.80.
So, combining the two amounts, we have:
80 * r + 5 * o = $1030.45
Now, we can substitute the first equation into the second:
80 * r + 5 * o = $1030.45
80 * r = $920.65
80 * r + 5 * o = $1030.45
5 * o = $1030.45 - $920.65
5 * o = $109.80
Finally, we can solve for the hourly rate of overtime work:
o = $109.80 / 5
o = $21.96/hour

The insurance be 7,5% of the daily rental amount and the GPS an additional R45 per day a.What will the total cost be for the car rental if they spent 6 days in Cape Town travelled 1650 km in total?
Answers
The daily rental cost is R200, so for 6 days, the rental cost will be 200 * 6 = R1200.
The insurance cost is 7.5% of the daily rental cost, so the insurance cost will be 0.075 * 200 = R15 per day. For 6 days, the insurance cost will be 15 * 6 = R90.
The GPS cost is R45 per day, so for 6 days, the GPS cost will be 45 * 6 = R270.
The additional cost for km driven is 1.8 * 1650 = R2970.
Adding up all the costs, the total cost will be R1200 + R90 + R270 + R2970 = C = R4530

Russell and Valerie start to walk away from the Cafeteria to their classes.
Russell walks 10 yards due West, then turns 40° toward South and walks 5 yards.
Valerie walks 10 yards due East, then turns 60° toward North and walks 5 yards.
Which student is farther from the cafeteria? Explain how you know using a diagram and words.
Answers
Russell first walks 10 yards due West, and then turns 40° towards South and walks 5 yards. The distance can be calculated using trigonometry. Let's call the distance Russell traveled towards the South "d". The horizontal distance (West) is 10 yards, and the vertical distance (South) is d. The two distances form a right triangle with an angle of 40°.
Using the Pythagorean theorem, we can calculate d:
d = sqrt(10^2 + d^2 - 2 * 10 * d * cos(40°))
d = sqrt(100 + d^2 - 20d * 0.766)
Expanding and solving for d, we find that d = 4.47 yards.
The total distance Russell traveled is
sqrt(10^2 + 4.47^2) = sqrt(100 + 19.99) = sqrt(119.99) = 10.97 yards
Valerie walks 10 yards due East and then turns 60° toward North and walks 5 yards. Let's call the distance she traveled towards the North "d". The horizontal distance (East) is 10 yards, and the vertical distance (North) is d. The two distances form a right triangle with an angle of 60°.
Using the Pythagorean theorem, we can calculate d:
d = sqrt(10^2 + d^2 - 2 * 10 * d * cos(60°))
d = sqrt(100 + d^2 - 20d * 0.5)
Expanding and solving for d, we find that d = 8.66 yards.
The total distance Valerie traveled is
sqrt(10^2 + 8.66^2) = sqrt(100 + 75.14) = sqrt(175.14) = 13.19 yards.
Since Valerie traveled a greater distance, she is farther from the cafeteria.

Graph the line through (2,0) with
m = -2.
Answers
Answer:
showed below
Explanation:
you can start by plotting a dot at (2,0), since the line must go through that point. Since m, the slope, is -2, you can re-write this into a fraction to make it easier, looking like this: -2/1. Slope in general can be written as “rise over run” or “rise/run”, so the numerator is how far you go up on the graph, while the denominator is how far you go over. In this case, the slope is negative, so instead of up and right, the line goes down and right. From (2,0) you would go down by 2, and right by one. At that point you polar another dot. That point is (3,-2). From there, you can take a straight edge and line it up with the two dots and draw your line. It looks like what is in the picture.

The toy company has the following additional constraints. The height must be no more than 15 inches greater than the radius. The area of the base must be at least 36pi square inches. Which of the following is a possible set of dimensions for the container?

B) radius 8 in., height 21 in
C) Radius., 7 inches., height 23 in
D) radius., 9 inches., height 18 inches
I NEED THIS IN LIKE 30 MINUTES PLEASE
Answers
Answer: To determine if a set of dimensions is possible for the container, we need to check if it satisfies both the inequality h > 0.3r^2 and the two constraints.
A) radius = 21 inches, height = 21 inches:
The inequality h > 0.3r^2 is satisfied (21 > 0.3 * 21^2).
The height must be no more than 15 inches greater than the radius (21 - 21 <= 15), which is satisfied.
The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is not satisfied (pi * 21^2 < 36pi).
So, option A is not a possible set of dimensions.
B) radius = 8 inches, height = 21 inches:
The inequality h > 0.3r^2 is satisfied (21 > 0.3 * 8^2).
The height must be no more than 15 inches greater than the radius (21 - 8 <= 15), which is satisfied.
The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is satisfied (pi * 8^2 >= 36pi).
So, option B is a possible set of dimensions.
C) radius = 7 inches, height = 23 inches:
The inequality h > 0.3r^2 is satisfied (23 > 0.3 * 7^2).
The height must be no more than 15 inches greater than the radius (23 - 7 <= 15), which is satisfied.
The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is not satisfied (pi * 7^2 < 36pi).
So, option C is not a possible set of dimensions.
D) radius = 9 inches, height = 18 inches:
The inequality h > 0.3r^2 is not satisfied (18 <= 0.3 * 9^2).
The height must be no more than 15 inches greater than the radius (18 - 9 <= 15), which is not satisfied.
So, option D is not a possible set of dimensions.
Therefore, the only possible set of dimensions is B) radius = 8 inches, height = 21 inches.

The possible value of angle X, to the nearest degree is 78°.
What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c
Given that, in ΔXYZ, x = 300 cm, z = 290 cm and ∠Z=109°.
Here, sinX/x=sinZ/z
sinX/300 = sin109°/290
sinX/300 = 0.9455/290
sinX/300 = 0.00326
sinX=0.00326×300
sinX=0.978
∠X=78°
Therefore, the possible value of ∠X, to the nearest degree is 78°.
