Given that,
In the picture there is a question with a graph.
From a tee box that is 6 yards above the ground, a golfer hit a ball. The graph displays the height of the golf ball above the ground in yards as a quadratic function of x, the golf ball's horizontal distance from the box in yards.
We have to find the domain of the function in the situation.
The domain is nothing but All of a function's x-values, or inputs, make up the domain, and all of a function's y-values, or outputs, make up the range.
The domain of a graph is every value in the graph, from left to right. The graph's entire range, from lower to higher numbers, represents the range.
Therefore, the Domain of the function is [0,230].

Abel owns a dog walking business. He walks12 dogs every day of the week. If Abel walks2.6 miles each day, how many miles does hewalk in one week?
Answers
Abel walks 2.6 miles each day of the week.
The week has 7 days.
So, to calculate how many miles he walks in one week we simply have to multiply the number of miles that he walks per day (2.6) by the number of days in a week (7).
2.6 miles per day x 7 days = 2.6 x 7 = 18.2 miles a week.

How can each type of sequence be helpful in everyday situations? Provide an example and the corresponding equation for each type.
Answers
Answer:
The two types of the sequence include
1) Arithmetic sequence
2) Geometric sequence
An arithmetic sequence is an ordered set of numbers that have a common difference between each consecutive term. For example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6. An arithmetic sequence can be known as an arithmetic progression.
The Nth term of an arithmetic sequence is given below as
[tex]\begin{gathered} T_n=a+(n-1)d \\ \text{Where,} \\ a=\text{first term} \\ n=Num\text{mber of terms} \\ d=\text{common difference}=T_2-T_1=T_3-T_2 \end{gathered}[/tex]A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
The Nth term of a geometric sequence is given below as
[tex]\begin{gathered} U_n=ar^{n-1} \\ \text{Where,} \\ a=\text{first term} \\ r=\text{common ratio=}\frac{t_2}{t_1}=\frac{t_3}{t_2} \end{gathered}[/tex]Real life illustrations of the types of sequence
Sequences are useful in our daily lives as well as in higher mathematics. For example, the interest portion of monthly payments made to pay off an automobile or home loan, and the list of maximum daily temperatures in one area for a month are sequences.
Example: arithmetic sequence
A boy building a tower with blocks uses 15 for the bottom row. Each row has 2 fewer blocks than the previous row. Suppose that there are 6 rows in the tower. Find a for n = 6
The number of blocks in each row forms an arithmetic sequence with a₁ = 15 and d= −2. The formula to be used is an = a₁ + (n − 1)d.
[tex]\begin{gathered} t_n=a+(n-1)d \\ T_6=15+(6-1)(-2) \\ T_6=15+5(-2) \\ T_6=15-10 \\ T_6=5 \end{gathered}[/tex]Hence,
On the sixth row, he will have 5 blocks left

(Type a whole number.) The number of square yards equivalent to this total area is 11.4 square yards. (Round to the nearest tenth as needed.) Since rubber flooring is sold in whole sq. yards, Juan must purchase exactly square yards.
Answers
The amount of rubber flooring will be the area of the floor.
We can calculate the area as the sum of two rectangles:
Then, the area is:
[tex]A=10\cdot4+9\cdot7=40+63=103ft^2[/tex]We can convert this area into square yards as:
[tex]A=103ft^2\cdot(\frac{1\text{ yd}}{3\text{ ft}})^2=103\cdot\frac{1}{9}\text{ yd}^2\approx11.44\text{ yd}^2[/tex]As we have to purchase a whole number of square yards, we will buy the next integer greater than 11.44, that is 12 sq yd.
Answer:
The floor area is 103 square feet.
This is equivalent to 11.44 square yards.
He has to purchase 12 square yards of rubber floor.

The financial advisor is NOT using percentages properly, because the 60% increase would multiply the new value after one year, and not the initial value.
So first let's find the investment after one year:

The line that passes through the point (1,-1) and is parallel to another line whose slope is 1 will be y = x-2.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that line that passes through the point (1,-1) and is parallel to another line whose slope is 1.
The standard from the equation is,
y = mx + c
The equation with slope 1 is,
y = x +c
For the y-intercept, the value of y is -1.
-1 = 1(1) + c
-1 = 1+c
c = -2
Substitute the value of the slope, m as -1 and c as -2 we get,
y = 1x-2
y = x-2

Step-by-step explanation:
The inside(interior) angles of a triangle must add up to 180 degrees. A line is 180 degrees, so the angle GFH (the measure of the acute angle at point F) would be 180-(11x+1)
Now we have information on all 3 angles of the triangle; they must sum up to 180, so add all of these equations together
180-(11x+1) = 179-11x
Add this to 3x+19 and 70 gives 268-8x=180
Solving this equation for x we get -8x=180-268
-8x=-88
x=11

Answer:
11°
Step-by-step explanation:
Here,
∠FGH=3x+19
∠GHF=70°
∠QFG=11x+1
Now,
11x+1+∠GFH=180[Sum of a straight line is 180°]
∴∠GFH=179-11x
Again,
∠GFH+∠GHF+∠FGH=180[Sum of all angles of a triangle is 180]
179-11x+70+3x+19=180
-11x+3x=180-179-70-19
-8x=-88

The law firm assigned a total of 19 lawyers to the case and was able to charge the client $19300 per day for these lawyers' services.
we need to determine the number of associates assigned to the case and the number of partners assigned to the case.
Suppose the number of associates is x and the number of partners be y.
Then the required equations are formed:
x+y=19 ..eq(1)
700x+1300y=19300 ...eq(2)
from eq(1) we get:
y=19-x .. eq(3)
Plug eq(3) into eq(2)
700x+1300(19-x)=19300
700x+24700-1300x=19300
700x-1300x=19300-24700
-600x=-5400
x=9
Thus, y=19-9
y=10
Thus the number of associates are 9 and the number of partners are 10.

Enrollment in finite mathematics plus enrollment in calculus is less than 300.
The first step in solving a word problem is identifying the variables. The variables in any algebraic expression is the unknown value, and to solve it we usually assign a letter to represent it (x and y being the most commonly used).
In the question above, we already know that the number of student enrollees is less than 300 and not equal to 300 (might as well be just 20, we do not know) but we do know that it is NOT EQUAL TO 300, but less than.
Also we do not know the number of those enrolled for finite mathematics, so we shall call that f. Those that enrolled for calculus we shall call c. Since both categories are less than 300, the two variables f and c can now be written as an inequality which reads,
f plus c is less than 300
That is;
f + c ⊂ 300

Let's draw the figure to better understand the scenario:
