Delilah received a stipend of $1,000 for the extra work she does on the job. She is going to deposit the money into her bank account that receives 4% simple interest.The account balance after year 3 is what
Answers
Answer:
$1,120
Step-by-step explanation:
Interest I = PRT/100 where P = amount deposited, R = rate percent and T = time.
So I = (1000 * 4 * 3) / 100
= $120.
So the account balance is 1,120 dollars.

so the slope of the line perpendicular to it is -1/2
so now put it in point slope form
y-(-4) = -1/2 (x-8)
Final answer:
To find the equation of a line perpendicular to y = 2x + 13 that contains the point (8, -4), we first determine the slope of the given line, which is 2. Then, we find the negative reciprocal of the slope to get the perpendicular slope, which is -1/2. Using the point-slope form of a line, we substitute the coordinates of the given point and the perpendicular slope to write the equation of the line.
Explanation:
To find the equation of a line perpendicular to y = 2x + 13 in point-slope form, we first need to determine the slope of the given line. The equation y = 2x + 13 is already in slope-intercept form, where the coefficient of x represents the slope. So, in this case, the slope is 2.
Since the line we are looking for is perpendicular to y = 2x + 13, we know that the slopes of the two lines are negative reciprocals of each other. Therefore, the slope of the line we're looking for is -1/2.
Now, we can use the point-slope form of a line, which is y - y1 = m(x - x1), to write the equation of the line. Plugging in the given point (8, -4) and the slope -1/2 into the equation, we get:
y - (-4) = -1/2(x - 8)
Simplifying further,
y + 4 = -1/2x + 4
Finally, simplifying the equation, we get:
y = -1/2x.

Crystal has 121 compact discs. The total number of boxes required are 5.
Solution:
Given, Crystal has 121 compact discs that she wants to put into boxes.
Each of the boxes that she brought home holds 25 discs.
We have to find how many of these boxes will she need for all of her discs?
Now, we know that, number of boxes required
Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.
Hence, the total number of boxes required are 5.

Answer:Complex numbers in the coordinate plane. Each complex number x + yi corresponds to a number pair (x, y) in the plane, so we may say that the complex numbers form a two-dimensional collection. The two coordinates of the pair (x, y) are called the real part and the imaginary part of the complex number.
