the amount of money rick earned can be solve using the
formula:
F = P (1+ i)^n
Where F is the future money
P is the initial money
i is the interest rate
n is the time
F = 1000 ( 1 + 0.04)^10
F = $ 1,480.24
Sally
F = 1000 + (50)(10)
F = $ 1500
So the answer is D

<em>If the radius of a sphere is doubled, the surface area becomes four times the original surface area.</em>
The equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
Step-by-step explanation:
Step 1; We need to determine the equation relating the x to the f(x) values from the given coordinates. y is the dependent value whereas x is the independent value i.e. y's value depends on x's value.
Step 2; If we multiply the x value with 2 and add the resulting answer with 1 we get the y value.
y = 2x + 1 is the equation that relates the values in the table.
Step 3; Now we substitute the values in the equation to see if it's correct.
For x = 0, y = 2(0) + 1 = 0 + 1 = 1,
For x = 2, y = 2(2) + 1 = 4 + 1 = 5,
For x = 3, y = 2(3) + 1 = 6 + 1 = 7.
So the equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
a) The equation is therefore; x³ + 3x² + 2x = 336
b) Solving for the length, we get the length to be; x = 6.
c) All workings are as shown below;
According to the question;
- When the height of a rectangular prism was halved, the volume was 168 cubic cm.
In essence, the volume of the original prism is;
Since, the original prism had a length, width, and height of consecutive integers, increasing in that order.
- Volume = x (x+1) (x+2) = 336
a) The equation is therefore;
- <em>x³ + 3x² + 2x = 336</em>
b) Solving for the length, x is as follows;
By testing values and checking;
- Upon solving the polynomial, x = 6.
c) All workings are as shown above.
