Lucy was born on 11/09/1993. How many eight-digit codes could she make using the digits in her birthday?
The number of eight-digit codes could she make using the digits in her birthday is 1120 digits
Since the order of the arrangement of the digits matter, we use permutations
What are permutations?Permuations are the number of ways of arranging n objects in r ways. It is given as ⁿPₓ = n(n - 1)(n -2)...(n - x + 1). If we have r identical objects out of n objects, the number of arrangements are n!/r!
Now, since in the date Lucy was born 11/09/1993 has eight digits, we need to find the number of permutations the eight digits of her birthday to form an eight digit code.
Since there are 8 digits, three one's, three nine's, one 1 and one 3.
The number of permutations of these digits in an eight digit code, since we have repeated objects are n = 8!/3!3!1!1!
= 40320/6 × 6 × 1 × 1
= 40320/36
= 1120 digits
So, the number of eight-digit codes could she make using the digits in her birthday is 1120 digits

Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Answer:
If the slope is 7/4x : y=-4/7x-6/7
Step-by-step explanation:
1) Find reciprocal of slope: 7/4 becomes -4/7
2) insert into equation y=mx+b: y=-4/7x+b
3) solve for "b" by substituting x and y with the point (2,-2): -2=-4/7(2)+b
b=-6/7
4) write final equation: y=-4/7x-6/7

Answer:
angle b measures 58°
Explanation:
As we know that, the sum of complementary angles is always equal to 90°.
Therefore,
angle a + angle b = 90°
32° + angle b = 90°
angle b = 90° - 32°
angle b = 58°

Answer:
They would be paying $189
The amount of money that the customer paying for 7,000 pieces is $189.
What is an equation?An equation is an expression that shows the relationship between two or more variables or numbers.
Number of bags for 7000 pieces = 7000/500 = 14
Cost for 7000 pieces = $0.03 * 7000 = $210
Discount = 210 - (0.1 * 210) = $189
The amount of money that the customer paying for 7,000 pieces is $189.

The graph below shows a company's profit f(x), in dollars, depending on the price of erasers x, in dollars, sold by the company:
Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and profit? (4 points)
Part B: What is an approximate average rate of change of the graph from x = 1 to x = 4, and what does this rate represent? (3 points)
Part C: Describe the constraints of the domain.
Part A: The x-intercept represents the maximum amount of profit the company makes depending on the price of erasers. The intervals would be the prices of the erasers, and they represent the correlation between sale and profit. For example, when each eraser costs $4, the company makes the max profit of $270.
Part B: The average rate of change would be $91.875 and the rate represents that, on average, for each dollar that the price of the eraser jumps, the profit jumps an average of $91.875.
Part C: The constraints of the domain would be things like how the price of the erasers cannot go less than $0 or above $8; 0 [tex]\leq[/tex] x [tex]\leq[/tex] 8.

How do you find out What is 3/8 x 4?
Answer: 1.5 (Decimal Form) or 3/2 (Exact Form)
Step-by-step explanation:
So what you do is put the whole number which in this case is 4, into a fraction so your problem will look like this:
3 / 8 * 4 / 1 =
Then, you will have to multiply all the numbers across:
3 * 4 = 12
8 * 1 = 8
Your answer will then look like this:
12 / 8
You will have to simplify with the greatest common factor which would be 4:
12 / 4 = 3
8 / 4 = 2
So, you get your answer:
3 / 2 or 1.5

The height of a triangle is 9 feet less than twice the length of its base. Its area is 9 square feet. What are the dimensions of its base and height? Recall that the area of a triangle is 1/2bh.
Its base is ____ feet and its height is ____ feet.
Step-by-step explanation:
If we let the length of the base be b, then the height is 2b-9.
This means that (1/2)(b)(2b-9)=9
b(2b-9) = 18
2b^2 - 9b = 18
2b^2 - 9b - 18 = 0
(2b+3)(b-6)=0
b = -3/2 or b= 6 (disregard b = -3/2 as distance is positive)
This means b =6, and thus the height is 2(6)-9=3.
