Antonio is working on programming a new video game called Millie's Quest. In the game, the main character, Millie, collects golden keys to help her in her quest. Antonio wants to write a formula to show that Millie can collect one less key than the highest number of bits that can be arranged in the system. What formula can he use?
Answer:
Formula = 2n-1
Step-by-step explanation:
Given : Antonio uses the power of 2n to find the number of ways bits can be arranged. The n often stands for the number of bits. Millie, collects golden keys to help her in her quest.
To write : A formula to show that Millie can collect one less key than the highest number of bits that can be arranged in the system.
Number of bits =n
Highest number of bits =2n
One less key than the highest number of bits = 2n-1
Therefore, the formula he use = 2n-1
B. 20 sq. in.
C. 44 sq. in.
D. 35 sq. in
Answer: D.
Step-by-step explanation:
Given: Side of equilateral triangle = 10 inches
Height of equilateral triangle= 7 inches
We know that the area of triangle is given by :-
Hence, the area of the given equilateral triangle =
Answer:
days ≤ 6
Step-by-step explanation:
she gas 160 pages out of the 380 pages, so she needs to write other:
380 - 160 = 120 pages.
If she writes a minimum of 20 pages per day, then the maximum number of days in which she will finish the book is:
20*d = 120
d = 120/20 = 6
so d is the number of days, and we have that:
d ≤ 6.
The equality is when she only writhes 20 pages per day, and if she writes more than that, then the number of days needed will be smaller than 6.
A x2−9
B x3−9
C (x+9)2
D (x−9)2
I know the answer is either A or B i might be wrong tho pls help im not sure.
Answer:
A
Step-by-step explanation:
In this question, we are concerned with selecting which of the options best represents the difference of two squares.
Let’s have an exposition below as follows;
Consider two numbers, which are perfect squares and can be expressed as a square of their square roots;
a^2 and b^2
where a and b represents the square roots of the numbers respectively.
Inserting a difference between the two, we have;
a^2 - b^2
Now by applying the difference of two squares, these numbers will become;
a^2 - b^2 = (a + b)(a-b)
So our answer out of the options will be that option that could be expressed as above.
The correct answer to this is option A
Kindly note that;
x^2 -9 can be expressed as x^2 - 3^2 and consequently, this can be written as;
(x-3)(x + 3)
