A. We are given that the combination is 1 letter and 8
digits, so the total number of unique combinations would be the product of each
possibilities.
Total unique ID’s = 26 * 10 * 10 * 10 * 10 * 10 * 10 * 10
* 10
or can also be written as
Total unique ID’s = 26 * 10^8
Solving:
Total unique ID’s = 2.6 x 10^9
B. Let us now calculate the total unique ID’s if there is
only 1 letter followed by 3 digits.
Total unique ID’s = 26 * 10^3
Total unique ID’s = 26,000
Since there are 48,000 students and only 26,000 unique ID’s,
therefore it is not enough.

A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.
Assuming the space inbetween -7x and 8y is a plus sign.
To get the equation in the right format, one must do the following:
8y=7x-1
y=7/8x-1/8
And theres your answer!
Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)
APR = Annual Percentage Rate; APY = Annual Percentage Yield.
This is a tough question!!
To get the APY we use the compounding formula (A = P(1+r/n)^nt) and put $1 in
for the principal and see what our final amount is at 19.07% after a year.
A = 1(1+.1907/12)^12
A= 1.0159^12
A= 1.2083 This means
that we paid 0.2083 on our dollar after a year which means the APY is 20.83%.
We have the formula: (spending : sum of spending) . 100 = ......
Answer:
The area of the trapezoid is 
Step-by-step explanation:
we know that
The area of a isosceles trapezoid is equal to the area of two isosceles right triangles plus the area of a rectangle
step 1
<em>Find the area of the isosceles right triangle</em>
Remember that
In a isosceles right triangle the height is equal to the base of the triangle
we have

so

The area is equal to

substitute the values

step 2
Find the area of the rectangle
The area of the rectangle is equal to

we have
-----> is the height of the trapezoid
-----> the diagonal of the rectangle
Applying the Pythagoras Theorem

The area of the rectangle is

step 3
Find the area of the trapezoid
