Step-by-step explanation:
We need to find the area of the semicircle and parallelogram separately and then combine.
The formula for the area of a semicircle is 1/2(pi*r^2)
r = 12. 12^2 = 144
1/2(pi*144) = 226..1946711 which we can just round to 226
The formula for the area of a parallelogram is bh
b = 18, h = 9. 18*9 = 162.
226+162 = 388
Answer:
218.55Step-by-step explanation:
total area = semi circle + parallelogram
= (1/2 π 6²) + (9 x 18)
= 56.55 + 162
= 218.55 sq. units
The quadratic parent function has been reflected down, stretched vertically by a factor of 1/3, shifted vertically by 9 units and shifted horizontally by -12 units.

1b) then rewrite the vertex form into standard form
Answer:
1a) f(x) = -1/3(x + 12)² + 9

Step 1: Define
Reflected down and vertically stretched by 1/3: a = -1/3
Shifted vertically by 9 units: d = 9
Shifted horizontally by -12 units: c = -12
Step 2: Write Vertex Form
Define: f(x) = a(bx - c)² + d Substitute: f(x) = -1/3(x + 12)² + 9Step 3: Write Standard Form
Define: f(x) = -1/3(x + 12)² + 9Expand: f(x) = -1/3(x² + 24x + 144) + 9Distribute -1/3: f(x) = -1/3x² - 8x - 48 + 9Combine like terms: f(x) = -1/3x² - 8x - 39And we have our final answers!

Let's assume your process yields products with a mean diameter of 12.50mm and σ = 0.010mm. If the specification calls for a range of 12.480mm - 12.530mm, what percentage of parts will have a diameter within these limits?
Answer:
There is a 97.59% that diameter of the product will fall in the specified range.
Step-by-step explanation:
Let X be the r.v. the diameter of a product
X~N(12.5, (0.010)²)
P(12.48 < X < 12.53) = P(X < 12.53) - P(X < 12.48)
Convert the x-values to corresponding z-values
[tex]Z_{1} = \frac{12.48 - 12.50}{0.01} = -2\\\\Z_{2} = \frac{12.53 - 12.50}{0.01} = 3\\\\[/tex]
Then, using the standard normal distribution cumulative probability tables:
[tex]P(X < 12.53) - P(X < 12.48) = P(Z < 3) - P(Z < -2)\\\\= P(Z < 3) - (1 - P(Z < 2))\\\\= 0.9987 - (1 - 0.9772)\\\\= 0.9987 - 0.0228\\\\= 0.9759[/tex]

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
F = Kq₁q₂ / r²
where F is the force, K is a constant, q1 and q2 are the charges on the two bodies, and r is the distance between them
On simplifying for r , we get
Multiply by r² on both sides , we get
Fr² = Kq₁q₂
Divide by F on both sides of the equation , we get
r² = ( Kq₁q₂ / F )
Taking square roots on both sides of the equation , we get
r = ( Kq₁q₂ / F )^1/2
Hence , the equation is r = ( Kq₁q₂ / F )^1/2

The total percent of reduction is _____% , so this __ * is or is not * __equal to a discount.
Step-by-step explanation:
Step one:
We are told that the store offers off 10% of sales, this means that the store is offsetting the price down by 10% hence a price reduction.
Moreso, a coupon is a voucher entitling the holder to a discount off a particular product. the coupon is 40%, hence this is equal to a discount, that is price reduction by 40%.
Step two:
Say the price of an item is $100, a coupon if 40% will entitle the holder to only pay $60, that is
=40/100*100
=0.4*100
=$40 off
= 100-40
=$60
The total percent of reduction 10+40= 50%
This is equal to a discount on the sales price

In 1990, about 13.8 million students were enrolled in U.S. colleges. In
2000, about 14.9 million students were projected to be enrolled in U.S.
colleges. Find the average rate of change in the number of students per
year.
Answer:
0.77% increase per year
Step-by-step explanation:
total % increase in the number of college students between 1990 and 2000:
= (14.9 - 13.8) / 13.8 = 1.1 / 13.8 = 0.07971 = 7.971%
average rate of increase per year:
1.07971 = (1 + r)¹⁰
¹⁰√1.07971 = ¹⁰√(1 + r)¹⁰
1.007699 = 1 + r
r = 1.007699 - 1 = 0.007699 = 0.77% increase per year

Suppose that your school's environmental club wants to travel to the state capital to participate in an Earth Day festival. The rental of a bus for the day will cost $895. Lunch and festival activities will cost $25 per student. Your club advisor thinks that the fee for participating should not be more than $60. How many students must be recruited for the trip. Write a mathematical model for this.
Answer:
Mathematical model is:
(895/n) + 25 ≤ 60
Number of students must not be less than 26
Step-by-step explanation:
We are told that;
- the rental of a bus for the day will cost $895.
- Lunch and festival activities will cost $25 per student
If the number of students are n, then cost per student for bus rent is; $895/n
Thus, total amount per n number of students to participate is;
895/n + 25
Now, we are told that the club advisor thinks that the fee for participating should not be more than $60.
Thus in form of inequality, we have;
(895/n) + 25 ≤ 60
Subtract 25 from both sides to get;
(895/n) ≤ 60 - 25
(895/n) ≤ 35
Multiply both sides by n and then divide both sides by 35;
895 ≤ 35n
26 ≤ n
