Hey there!
To solve this problem, we will take a look at the FOIL Method.
What is "FOIL"?FOIL is a simple acronym that can be used to multiply binomials. It stands for:
F - Front
O - Outer
I - Inner
L - Last
See the image below for an example of how to use this in the given situation.
ApplyFront: Multiply the two terms out in the front.
[tex](-5a)(-4a) = 20a^2[/tex]
Outer: Multiply the two terms on the outsides.
[tex](-5a)(3)=-15a[/tex]
Inner: Multiply the two terms on the insides.
[tex](6)(-4a)=-24a[/tex]
Last: Multiply the two terms in the back.
[tex](6)(3)=18[/tex]
AddNow, we add all of our answers from above:
[tex]20a^2-15a-24a+18[/tex]
SimplifySimplify by combining like terms:

Using translation concepts, we have that:
a) The parent function is f(x) = |x|.
b) The transformations were a reflection over the x-axis, vertical stretch by a factor of 2 and a shift down of 3 units.
c) The graph is given at the end of the answer.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the parent function is given by:
f(x) = |x|.
The transformations are given as follows:
Reflection over the x-axis, as the function was multiplied by a negative number.Vertical stretch by a factor of 2, as the function was multiplied by a number that has absolute value 2.Shift down of 3 units, as 3 was subtracted from the function.The graph of the two functions, the parent(red) and the translated(blue), is given at the end of the answer.

Answer: 2: v = -26 | 3: k = 7 | 4: x = 3/14 |
Step-by-step explanation:
---------------------------------------------------------------------------------------------------
2: 4 + v/8 = 3/4
First we have to leave the variable "v" alone and we do the opposite on the other side.
So we do 4 + v/8 = 3/4 ----> v/8 = 3/4 - 4
---> v/8 = -3 1/4
next we do 8 * v/8 = -3 1/4 * 8
We get v = -26
---------------------------------------------------------------------------------------------------
3: 2/3 + 3/4k = 71/12
Subtract 2/3 from both sides
= 3/4k = 63/12
Reduce 63/12 to 21/4
= 3/4k = 21/4
Multiply each side by 4/3, the reciprocall of 3/4
then we get k = 21/3
Which means k = 7
---------------------------------------------------------------------------------------------------
4: 1/2 + 7/10x = 13/20
Subtact 1/2 from both sides
= 7/10x = 3/20
Multiply each side by 10/7, the reciprocal of 7/10
x = 3 * 10/20 * 7
= x = 30/140
= x = 3/14
translate the following statement into an equation and solve for x: the number 80 is the product of "-10" and x
The value of x is -8 in the equation.
How to calculate the equation?It should be noted that the information is that the number 80 is the product of "-10" and x.
This will be represented as:
-10 × x = 80
-10x = 80
Divide both side by -10
-10x/-10 = 80/-10
x = -8
Therefore, the value of x is -8.

find the intersection of the three sets: A={-2,7,8,11}, B={-2,7,11}, C={-2,8,11}
The intersection of three sets A,B and C is {₋2 , 11}.
Given set A = {₋2,7,8,11}
set B = {₋2,7,11}
set C = {₋2,8,11}
we need to find A∩B∩C.
The components shared by all the sets A, B, and C are given by the intersection of A and B as a set. A ∩ B ∩ C is a notation that can be used to indicate the intersection of A, B, and C.
To obtain A intersection B intersection C, first determine the common elements of sets A and B, or A ∩ B. Then determine the common elements of sets B and C, or B ∩ C. Finally, compute the common elements of these two results.
we first find:
A∩B = {₋2,7,8,11} ∩ {₋2,7,11}
= {₋2,7,11}
then B ∩ C = {₋2,7,11} ∩ {₋2,8,11}
= {₋2 , 11}
now (A∩B) ∩ (B∩C) = {₋2,7,11} ∩ {₋2 , 11}
= {₋2 , 11}
hence we get the intersection of three sets as {₋2 , 11}

The center of segment FG is located at point N. Write the formula that expresses FG if FN = 2z2 + 4z + 3.
Since O represents the midway, both FO and OG must be equal.
3x + 17 = 7x - 15
Add 3x to both sides and subtract:
17 = 4x -15
To both sides, add 15:
32 = 4x
Subtract 4 from both sides:
x = 32/4
X = 8
Now that you know the value of X, find the lengths:
FO = 3x +17 = 3(8) +17 = 24 +17 = 41
OG = 7x -15 = 7(8) -15 = 56-15 = 41

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.
In weekday = 10000
In weekend = 8000

If there are 52 weeks in a year, how many more hours does a squirrel sleep in a year than a rabbit?
The squirrel sleeps 2548 hours more than the rabbit.
Difference of the numbers
Difference of the numbers means the result of subtracting one number from another.
Given,
If there are 52 weeks in a year,
Then we need to find how many more hours does a squirrel sleep in a year than a rabbit.
First, we have to find the sleeping pattern of squirrel and rabbit.
A squirrel spends up to 60% of its day asleep, which means that an average squirrel sleeps for almost 15 hours each day.
Similarly, the rabbits are sleep six to eight hours each day.
So for one day,
Rabbit = 8 hours per day
Squirrel = 15 hours per day.
Then the sleeping hours for one week is
Rabbit = 8 x 7 = 56 hours
Squirrel = 15 x 7 = 105 hours
So, for 52 weeks, they spend
Rabbit = 56 x 52 = 2912
Squirrel = 105 x 52 = 5460
So, the difference is
=> 5460 - 2912
=> 2548
Therefore, the squirrel sleeps 2548 hours more than the rabbit.

Identify the vertex, axis of symmetry, and direction of the graph of each function. Compare the width of the graph to the width of the graph of f(x)=x^2
===================================================
Explanation:
Compare the equation
[tex]y = (x-2)^2 - 4[/tex]
to the vertex form
[tex]y = a(x-h)^2 + k[/tex]
we have:
a = 1h = 2k = -4The vertex is located at (h,k) = (2, -4). Nice job on getting the correct answer for the vertex.
The axis of symmetry is x = 2 since the axis of symmetry goes through the vertex. It's the vertical mirror line.
Because a = 1 is positive, the parabola opens upward. It forms a bowl shape. The vertex is the lowest point.
If a < 0, then the parabola would open downward and have a highest point.

A $44,200.00 principal earns 5% interest, compounded annually. After 4 years, what is the balance in the account? Round to the nearest cent.
The balance amount at the end of 4 years in the account will be $53275
Principal amount= $44200
Rate of interest = 5% compounded annually
Number of years amount is invested for: 4 years
The formula for compound interest is given by:
A = P(1 + r/100)^n
where A = Final amount
P = principal amount invested
r = Rate of interest annually
n = number of years amount is invested
Putting the values in the formula we get:
A = 44200(1 + 5/100)^4
= 44200(1.05)^4
=44200*1.21
Amount at end of 4 years= 53725.37 or 53725
