The function rule after the given transformation is g(x) = -3x
What is a function?A function is defined as a relation between a set of inputs having one output each.
We have,
f(x) = 9x
Vertical compression = 1/3
Reflection in x-axis.
We know that when we compress a function f(x) by scale factor m
The new compress function is represented:
F(x) = m(f(x))
Reflection across the x-axis changes the sign of the new function.
Now,
With the vertical compression:
F(x) = 1/3 (f(x))
F(x) = 1/3(9x) = 3x
With the reflection in the x-axis:
g(x) = - F(x)
g(x) = -3x
Thus the function rule after the given transformation is g(x) = -3x

the number of pigs: the number of goats = 11:3
If there are 12 goats in the field, how many pigs are there?
Answer:
44pigs
Step-by-step explanation:
12/3=4.
4*11=44
The ratio shows how many times one value is contained in another value.
The number of pigs is 44.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The number of pigs: the number of goats = 11:3
Let the number of pigs = 11x
Let the number of goats = 3x
The number of goats = 12
This means,
3x = 12
Divide 3 on both sides.
x = 12/3
x = 4
Now,
The number of pigs:
= 11x
= 11 x 4
= 44
Thus,
The number of pigs is 44.

Prior to an election, 6,504 people vote in the advance polls for a riding. On election day, thepolling stations for that riding record an average of 407 voters per hour. How long were thepolls open on election day, if a total of 10,167 people voted in that riding?
**USE LET STATEMENTS, AND THEREFORE STATEMENTS**
The number of hours the polls open on the election day was 9 hours
From the question, we are to determine how long the polls opened on the election day
From the given information,
6,504 people vote in the advance polls for a riding prior to the election
and
A total of 10,167 people voted in that riding
Thus,
The number of people that voted on the election day = 10167 - 6504
Number of people that voted on the election day = 3663
Also, from the given information
The polling stations for the riding record an average of 407 voters per hour
Then,
Number of hours the polls open on election day = Number of people that voted on the election day ÷ Average number of voters per hour
Number of hours the polls open on election day = 3663 ÷ 407
Number of hours the polls open on election day = 9 hours
Hence, the number of hours the polls open on the election day was 9 hours

To multiply two fractions, you just multiply the top×top and bottom×bottom.
You could simplify it at this point but I waited to the end to simplify. See image.
Next, divide. If you have one or two fractions in a division problem, rewrite the division as a multiplication using Keep-Change-Flip! Keep the first term. Change divide to multiply. And Flip the second term (use the reciprocal is the math word for it.) See image.
Last, simplify.

The first four terms of the sequence are 7, 17, 37 and 77, respectively.
How to determine the first four terms of a sequence by a recursive formula
Sequences can be generated by using recursive formulas, that is, formulas that are in terms of the previous elements of a sequence. Herein we find a case of sequences by using recurrence formulas, whose procedure is shown below:
n = 1
f(1) = 7
n = 2
f(2) = 2 · f(1) + 3
f(2) = 17
n = 3
f(3) = 2 · f(2) + 3
f(3) = 37
n = 4
f(4) = 2 · f(3) + 3
f(4) = 77

The equation which expresses c in terms of p, m and t as in the task content is; c = mt + p and the solution of the equation for t is; t = (c -p)/m.
What is the equation of the situation such that c is expresses in terms of p, m and t?It follows from the fact that the rate of change, m is constant in the situation described. Hence, the equation is a linear equation.
On this note, the required equation which represents total cost, c in terms of p, m and t can be written as;
C = mt + p.
Hence, to solve the equation above for t;
Subtract p from both sides so that;
c - p = mt
Divide both sides by m;
(c - p)/m = t.
Ultimately, The equation which expresses c in terms of p, m and t as in the task content is;
c = mt + p

What is the value is 1/a+1/b+1/c
When a, b and c are the polynomials roots
Answer:
2/3.
Step-by-step explanation:
α + β + γ = -b/a
αβ + βγ + γ α = c/a
αβγ = -d/a
These are the relation between the roots α, β and γ and the coefficients of the cubic equation:
P(x) = ax^3 + bx^2 + cx + d
Our equation is:
P(x) = 4x³ – x² − 6x + 9
So, for the above equation:
a + b + c = -(-1)/4 = 1/4
ab + ac + bc = -6/4 = -3/2
abc = -9/4.
1/a + 1/b + 1/c
= (bc + ac + ab) / abc
So, plugging in the above values:
this = (-3/2) / (-9/4)
= 3/2 * 4/9
= 12/18
= 2/3.

You can multiply two matrices only if their dimensions are compatible. That means the number of columns in the first matrix is equal to the number of rows in the second matrix.
The resulting matrix, called the matrix product, has the number of rows of the first and the range of columns of the second matrix. The result of matrices A and B is denoted as AB.
The definition of matrix multiplication means row-by-column multiplication, where the entry in the ith row of A is multiplied by the corresponding entry in the jth column of B, and the results are added. Matrix multiplication is not commutative. If neither A nor B is identity matrices, then AB≠BA.

Write a function for each situation. Then find the value of each function after five years. Round to the nearest dollar. A $ 12,500 car depreciates 9 % each year.
7800 is the value of each function after five years.
With an example, what is compound interest?
When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits. Consider that you have $1,000 in a savings account earning 5% interest annually. If you made $50 in the first year, your new balance would be $1,050.The formula is: A = P( 1 + r )ⁿ
r = 0.09
As here the value of the car depreciates every year, so we need to plug the value of as negative. So, - 0.09
Now plugging the above values into the formula, we will get
A = 12500 ( 1 - 0.09)⁵
A = 12500 * ( 0.91)⁵
A = 12500 * 0.6240321451

The population in the city in 2020 to the nearest 100 is 235242.65.
The population of the city was 228,000 in the year 2010.
From 2010 to 2015, the population grew by 7.7%.
The population decreases by 4.2 % from 2015 o 2020.
Initially, the population of the city is 228,000.
From 2010 to 2015,
The city's population increased by 7.7%.
7.7% of 228,000 = ( 7.7 / 100) × 228,000 = 17556
The population of the city from 2010 to 2015 = 228,000 + 17556 = 245556
From 2015 to 2020,
Now, the city's population decreases by 4.2%.
4.2% of 245556 = ( 4.2 /100) × 245556 = 10313.352.
Therefore,
The population of the city in the year 2020 = 245556 - 10313.352 = 235242.648

A kitten has 5 claws on its paw, a chicken has 4. there are 57 kittens and chickens in the yard and they all have 768 claws. how many kittens and chickens are in the yard?
Using algebraic expressions and equation, there are 26 kittens and 31 chickens in the yard.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that there are 57 kittens and chickens in the yard, we can express this as:
x + y = 57 ⇒ x = 57 - y (equation 1)
where x = number of kittens
y = number of chickens
If a kitten has 5 claws on each of its 4 paws, and a chicken has 4 claws in each of its 2 feet, and they all have 768 claws, then
5(4)x + 4(2)y = 768 ⇒ 20x + 8y = 768 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
20(57 - y) + 8y = 768
1140 - 20y + 8y = 768
-12y = -372
y = 31
number of chickens = 31
Substitute the value of y in either of the two equations and solve for x.
x = 57 - y
x = 57 - 31
x = 26
number of kittens = 26
