Therefore , the solution of the given problem of function comes out to be (g - f)(-1) = 29.
What exactly does function mean?The math lesson covers an extensive variety of subjects, including geometry, integers, one's divisions, construction, and both real and imagined geographic places. A work covers the connections between various variable that all work together to produce the same result. A utility is made up of a variety of distinctive components that cooperate to create distinct results for each input.
Here,
We must first evaluate g(-1) and f(-1) before subtracting the results to obtain (g - f)(-1).
We possess
=> g(x) = 5x + 18
=> g(-1) = 5(-1) + 18 = 13
=> f(x) = x² - 17
=> f(-1) = (-1)² - 17 = -16
Therefore:
=> (g - f)(-1) = g(-1) - f(-1) = 13 - (-16) = 29
So, (g - f)(-1) = 29.

Answer:
The correct answer is B: Saturday.
The relationship between Monday and Thursday is that they are two days apart in a typical Monday-to-Sunday week. Similarly, Friday is also two days apart from Tuesday in a typical week, so the relationship between Friday and Tuesday would be the same as the relationship between Monday and Thursday. Therefore, the correct answer is B: Saturday.

Given the sequence - 3, 4, 11, 18, Amanda was asked to find the 58th term. She wrote the explicit formula below. Her teacher Ms. Felton informs her that her response is incorrect.

How should she correct it?
The given sequence is
\(-3,4,11,18\)As you can observe, this sequence as a difference of 7, that is, each new term is the sum of the previous term with seven.
Arithmetic sequences are defined by
\(a_n=a_1+(n-1)d\)Where, in this case, we have
\(\begin{gathered} a_1=-3 \\ d=7 \\ n=58 \end{gathered}\)Replacing these values, we have
\(a_{58}=-3+(58-1)7=-3+(57)7=-3+399=396\)The 58th term is 396.
(a) The reason why Amanda is wrong is she used 18 as the first term which is not correct because 18 is the fourth term of the sequence.
(b) To correct her mistake, she just needs to use -3 as the first term in the formula.

The measure of ZPQR is approximately 113°. This can be solved usiing the concept of geometry.
What is Geometry?One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects. A geometer is a mathematician who specializes in geometry.
Therefore, to find the measure of ZPQR, we would follow the following steps:
Let x= measure of <PQR
Hence, the measure of <PQR
296 = x/360 x 3.14 x 2 x 150

Help Please!!! Use the associative property to explain why the following statement is true. Any number that has 9 as a factor also has 3 as a factor.
Answer:
Step-by-step explanation:
3x3=9
The statement is true that the number that has 9 as a factor also has 3 as a factor.
What is the associative property of addition?Suppose you've got 3 numbers a, b, and c.
Then, we have (a+b) + c = a + (b + c)
This property is called an associative property and it is called because we can associate b with a, or b with c without altering the value of the addition.
We have been given the phrase "Any number that has 9 as a factor also has 3 as a factor"
3 x 3 = 9.
Here using the associative property of multiplication;
a x b = b x a = ab
So, we can see that any number that has 9 as a factor also has 3 as a factor.
18 = 9 x 2
Or 18 = 3 x 3 x 2
Thus, the statement is true that the number that has 9 as a factor also has 3 as a factor.

Answer:
10 ft
Step-by-step explanation:
The formula for the area of a triangle can be used. Put the known values into the formula and solve for the unknown.
A = (1/2)bh
15 = (1/2)(3)h
h = 15/1.5 = 10
The triangle's height is 10 feet.
Answer:
10
Step-by-step explanation:
A=1/2*b*h
15=1/2*3*h
15=3/2*h
15=3/2h
h=15/(3/2)
h=(15/1)(2/3)
h=30/3

A motorboat travels 116 kilometers in 4 hours going upstream. It travels 164 kilometers going downstream in the same amount of time. What is the rate of the
boat in still water and what is the rate of the current?
Rate of the boat in still water:
Rate of the current:
9514 1404 393
Answer:
boat: 35 km/hcurrent: 6 km/hStep-by-step explanation:
Let b and c represent the rates of the boat and current, respectively. Then the upstream rate is ...
speed = distance/time
b -c = (116 km)/(4 h) = 29 km/h
b +c = (164 km)/(4 h) = 41 km/h
Adding these equations gives ...
2b = 70 km/h
b = 35 km/h
Substituting into the first equation, we have ...
35 -c = 29
c = 6
Rate of the boat: 35 km/h.
Rate of the current: 6 km/h
The Lucas sequence is like the Fibonacci sequence except that the starting numbers are 2 and 1 instead of 1 and 0. What are the first ten terms of the Lucas sequence?
The first ten terms of the Lucas sequence are 2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843.
What is Lucas sequence?The Lucas sequence or Lucas series are an integer sequence named after the mathematician francois Edouard Lucas, which are similar to the Fibonacci numbers, each Lucas number is defined to be the sum of its two immediate previous terms, thereby forming a fibonacci integer sequence.
Now, the sequence of first 10 numbers of Fibonacci series are-
0, 1, 1 ,2, 3, 5, 8, 13, 21, 34
which are defined as set of integers that starts with zero, followed by a one,then by another one and then by series of steadily increasing numbers,The sequence follow the rule that each number is equal to the sum of preceding two numbers.
And the sequence of Lucas sequence is -
2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843.
which is definedas the sum of its two immediate previous terms.
The Lucas number may thus be defined as follows;
Ln = \(\left \{ {{2} ; if n= 0 \atop {1}; if n = 1} \right.\)
Here we can see that Lucas series starts with 2 and 1 whereas Fibonacci series starts with 0 and 1.
Hence,The first ten terms of the Lucas sequence are 2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843.

During a sale at the local department store, you buy three sweatshirts and two pairs of sweatpants for$85.50. Later, COACH Ike returned to the same store and bought three sweatshirts and four pairs ofsweatpants for $123. What is the sale price of each sweatshirt and each pair of sweatpants? i need help please
We are going to formulate a system of equations to represent this situation and the we are going to solve it.
Let x represent the sale price of one sweatshirt.
Let y represent the sale price of one pair of sweatpants.
3x + 2y = 85.5 (Equation 1)
3x + 4y = 123 (Equation 2)
Using the elimination method to solve the system, we have:
c-3x - 4y =- 123
----------------------
0 - 2y = -37.5 ( Subtracting the equation 2 from the equation 1)
y= 18.75 ( Dividing by 2 on both sides of the equation)
Replacing y=18.75 in the equation 1 to solve for x, we have:
3x + 2(18.75) = 85.5
3x + 37.5 = 85.5 (Multiplying)
3x = 48 (Subtracting 37.5 from both sides of the equation)
x= 16 (Dividing by 3 on both sides of the equation)
The answers are:
The sale price of one sweatshirt is $16.
The sale price of one pair of sweatpants is $18.75.

A parallelogram has sides measuring 10 and 18, and an angle measuring 100 degrees. What is its area?
Answer:
180
Step-by-step explanation:
The area of a parallelogram is given by the formula A = b × h, where b is the base and h is the height. In this case, the base is 10 and the height is 18. Therefore, the area is:
A=10×18
A=180
The area of the parallelogram is 180 square units
