The value of CD is 9.92 cm
How to find this value?Given:
∆ABC,CD ⊥ AB,AC = BC,Area of ABC = 32 cm2,m∠A = 72°Find: CD
Triangle ABC is an isosceles triangle with base AB, because AC = BC. In isosceles triangle angles adjacent to the base are congruent. So,
m<A = <mB = 72°
The sum of the measures of all interior angles is 180°, thus
m<C = 180° -72° - 72° = 36°
The area of the triangle ABC is
AABC= 1/2AC.BC.sin<C
If we expand,

Answer: The LARGEST angle has a measure of
degrees.
The largest angle of the triangle is ∠C = 66°
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
Now , the measure of ∠A = measure of ∠B = x
And , the measure of ∠C = measure of ∠A + 9°
Substituting the values in the equation , we get
x + x + ( x + 9 ) = 180
On simplifying the equation , we get
3x + 9 = 180
Subtracting 9 on both sides of the equation , we get
3x = 171
Divide by 3 on both sides of the equation , we get
x = 57°
So , the measure of ∠A = 57°
Now , the measure of ∠C = 57 + 9 = 66°
Hence , the measure of ∠C of triangle is 66°

A linear function is given.
g(x) = −6x + 1
(a) Find the average rate of change of the function between
x = a
and
x = a + h.
(b) Find the slope of the line.
The average rate of change of the function between x = a and x = a + h is -6
The slope is -6
How to determine the average rateFrom the question, we have the following parameters that can be used in our computation:
g(x) = -6x + 1
The interval is given as
x = a and x = a + h
So, we have
g(a) = -6a + 1
g(a + h) = -6(a + h) + 1
This gives
g(a) = -6a + 1
g(a + h) = -6a + -6h + 1
Subtract the functions
g(a) = -6a + 1
g(a + h) = -6a + -6h + 1
g(a) - g(a + h) = -6h
The average rate is then calcualated as
Average = [g(a) - g(a + h)]/(a - a - h)
This gives
Average = (-6h)/-h
Evaluate
Average = -6

Maria's abuela gave her $2000.00 for her quinceañera under the condition that she had to deposit it in a savings account for 42 months. How much interest will she have if the account earns 7.8% per annum simple interest?
Answer:
$ 546.00
Step-by-step explanation:
Simple Interest = P x r x t
where t = number of years
r = interest rate per year as a decimal
P = amount invested(deposit)
We are given that r = 7.8% per year = 7,8/100 = 0.078
However, since this is the yearly interest, the monthly interest = 0.078/12
The time period is 42 months
Initial deposit = $2,000
Therefore interest
I = 2000x (0.078/12) x 42 = $ 546.00

What are functions?Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Given |x - 3| < δ, we want to find a value of delta such that |5x - 15| < 0.001.
Starting with the inequality |x - 3| < δ, we can substitute x = 3 + delta or x = 3 - δ. Let's consider the case x = 3 + δ,
|5x - 15| = |5(3 + δ) - 15|
= |15 + 5δ- 15|
= |5δ|
Now, we want |5δ| to be less than 0.001. So, we can divide both sides of the inequality by 5,
|5δ|/5 < 0.001/5
|δ| < 0.001/5
Therefore, if the delta is less than 0.001/5, we have |5x - 15| < 0.001.
Similarly, if x = 3 - delta, we have:
|5x - 15| = |5(3 - δ) - 15| = |15 - 5δ - 15| = |-5δ|
|-5δ|/5 < 0.001/5
|δ| < 0.001/5
So, if δis less than 0.001/5, then |5x - 15| < 0.001 for both x = 3 + delta and x = 3 - δ.
Therefore, if |x - 3| < 0.001/5, then |5x - 15| < 0.001.
So, δ= 0.001/5 = 0.0002.

Mrs. Parker is a librarian at Eastside Library. In examining a random sample of the library's book collection, she found the following.
753 books had no damage, 74 books had minor damage, and
30 books had major damage.
Based on this sample, how many of the 76,500 books in the collection should Mrs. Parker expect to have minor damage or major damage? Round your answer
to the nearest whole number. Do not round any Intermediate calculations
Answer: Around 9,284 books.
Step-by-step explanation:
First, we will find how large this sample is by using addition.
753 + 74 + 30 = 857
Next, since we are looking for the expected minor or major damage, we will find the number of books from this sample that meet the requirements.
74 + 30 = 104
Now, we will find the percentage of this sample that meets the criteria.
(104 / 857) * 100 ≈ 12.13536%
Lastly, we will use this value to determine how many books in the collection are likely to have minor or major damage.
76,500 * 12.13536% = 9,283.55 ≈ 9,284 books
Answer:
Mrs. Parker should expect around 9284 books in the library's collection to have minor damage or major damage.
Step-by-step explanation:
To calculate the expected number of books with minor or major damage in the entire collection, we can scale up the sample proportion to the size of the full collection.
First, let's find the proportion of books with minor or major damage in the sample:
Proportion = (74 + 30) / (753 + 74 + 30) = 104 / 857 = 0.1214
Next, we'll scale up this proportion to the size of the full collection:
expected number of books with minor or major damage = proportion * 76,500 = 0.1214 * 76,500 = 9283.5472578763
Finally, we round the result to the nearest whole number:
expected number of books with minor or major damage = round(9283.5472578763 ) = 9284
So, Mrs. Parker should expect around 9284 books in the library's collection to have minor damage or major damage.

What is inductive reasoning?Inductive reasoning is defined as, tempting judgments by moving from the details to the fact. It's usually determined with inferential reasoning, where you move from known information to precise conclusions.
Here,
Asking each regular customer which flavor they would like to see in the shop would be the best method because the customers are the ones who will be buying and consuming the ice cream, so their preferences are the most important. By directly asking the customers for their opinions, the owner can get a better understanding of what flavors people are interested in, and it can also help to build a relationship with the customers by showing that their input is valued.
Option A, determining the current best-selling flavor, would only provide information about the current sales and not necessarily reflect customers' interests in new flavors. Option B, visiting other ice cream shops, could provide some ideas, but it would not necessarily reflect the local market and the preferences of the shop's specific customer base.

What is a cost function?
For some fixed factor prices, the cost function calculates the lowest cost of generating a specified level of output. The economic potential of a corporation is described by the cost function.
According to the cost function, the optimal assignment in order to minimise the total cost is by assigning:
Job J1 to machine M2 having a cost of 11
Job J2 to machine M3 having a cost of 12
Job J3 to machine M1 having a cost of 14
Job J4 to machine M4 having a cost of 11

Composition function
The composite function is given below with examples.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Consider two functions f(x) and g(x).
Now,
f o g = f(g(x)) is called a composite function.
f(x) = 2x + 1
g(x) = x + 2
So,
(f o g)(x)
= f(g(x))
= f(x + 1)
= 2 (x + 1) + 1
= 2x + 2 + 1
= 2x + 3
Thus,
The composite function is given above with examples.
