A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four terms in the sequence?
A.−5, 4, 13, 22
B.9, 4, −1, −6
C.−5, −45, −405, −3645
D. 9, −45, 225, −1125
Answer:
B.9, 4, −1, −6
Step-by-step explanation:
A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four terms in the sequence?
A.−5, 4, 13, 22
B.9, 4, −1, −6
C.−5, −45, −405, −3645
D. 9, −45, 225, −1125
From the above question,
A sequence can be generated by using an=a(n−1)+9, where a1=−5
The formula = an = a1 + (n - 1)d
a1 = First term
d = common difference = 9
We are to find the first 5 terms
First term = a1 =
an=an−1+9, where a1=−5
The formula =
a1 = -5 (1 - 1) + 9
= -5(0) 9
= -9
Second term = a2 =
an=an−1+9, where a1=−5
The formula = an = a1 (n - 1) + d
a2 = -5(2 - 1) + 9
= -5(1)+ 9
= -5 + 9
= 4
Third term = a3 =
an=an−1+9, where a1=−5
The formula = an = a1(n - 1) + d
a3 = -5(3 - 1)9
= -5(2) + 9
= -10+ 9
= -1
Fourth term = a2 =
an=an−1+9, where a1=−5
The formula = an = a1(n - 1) + d
a4 = -5(4 - 1)9
= -5(3) +9
= -15 +9
= -6

Consider the following equation 70 = bx + 7
What value of b will result in the solution x = -9?
A: 11
B: -11
C -7
D 7
Answer:
I think the answer us C.
Step-by-step explanation:
70-7=63. 9×7=63 so we now know the two values. if the outcome is a positive number then both answers must be negative (negative times negative=positive).
Answer:
-7
Step-by-step explanation:
70=bx+7
70=b(-9)+7
70=-9b+7
-7. -7
63=-9b
÷-9 ÷-9

Meghan has her own business. When she makes money, it is called income. When she spends money, it is called expenses. Choose the phrases below to explain how to use positive or negative integers to represent income and expenses. You would use positive integers to represent income because it is a Choose... amount. You would use negative integers to represent expenses because they are opposites of income.
Answer and explanation:
When you use positive interger to represent income, it shows that there has been an addition instead of a subtraction in money value to the business. In other words money is coming in instead of going out. Example when there is profit on goods sold say $10, it is indicated with a positive integer 10 to indicate addition in terms of operating income
When you use a negative value to represent expense, it indicates there has been a subtraction instead of an addition in money value. In other words money is going out of the business and not coming in. Example when there is a transportation expense to convey goods to the buyer, it is recorded as expenses subtracted from say revenue sales of the business. expenses are usually indicated in brackets in accounting to show negative value, although not a requirement since they are already named and recognized as expenses and subtracted regardless
Sydney asked her friends to write down the number of hours they practice their instruments each week. The data is shown.
1, 6, 6, 5, 2, 2, 0,5,6,7
What is the median of the data?
Answer:
5.5
Step-by-step explanation:
if you order the number from least to greatest like this 0,1,2,2,5,5,6,6,6,7 the median is the median number so here the median is 5.5 the reason it is 5.5 is bc the middle number is 5 and 6 and the middle number of that is 5.5

Check all of the polynomial functions that have 2 as a root.
h(m) = 8 – m3
f(g) = g3 – 2g2 + g
f(a) = a3 – 4a2 + a + 6
f(x) = x3 – x2 – 4
Answer:
Explained below
Step-by-step explanation:
Polynomial Roots
If x=a is a root of f(x), then f(a)=0
We will test the following functions to check if a=2 is a root.
[tex]h(m)=8-m^3[/tex][tex]h(2)=8-2^3=8-8=0[/tex]
Thus m=2 is a root of h
[tex]f(g)=g^3-2g^2+g[/tex][tex]f(2)=2^3-2\cdot 2^2+2[/tex]
[tex]f(2)=8-2\cdot 4+2=8-8+2=2[/tex]
Thus g=2 is not a root of f
[tex]f(a) = a^3 - 4a^2 + a + 6[/tex][tex]f(2) = 2^3 - 4\cdot 2^2 + 2 + 6[/tex]
[tex]f(2) = 8-16+8=0[/tex]
Thus a=2 is a root of f
[tex]f(x) = x^3 - x^2 - 4[/tex][tex]f(2)=2^3 - 2^2 - 4[/tex]
[tex]f(2)=8 - 4 - 4=0[/tex]
Thus x=2 is a root of f

the graph of the absolute value parent function, f(x) = |x|, is stretched horizontally by a factor of 5 to create the graph of g(x). what is the function of g(x)?
a. g(x) = |x+5|
b. g(x) = |1/5 x|
c. g(x) = |5x|
d. g(x) = 5 |x|
Answer: I’m thinking the answer is B
Step-by-step explanation:
Transformations are used to move a function from one position to another. The function of g(x) is [tex]g(x) = |\frac x5|[/tex]
Given that:
[tex]f(x) = |x|[/tex]
The rule of a horizontal stretch by factor k is:
[tex](x,y) \to (\frac xk,y)[/tex]
This means that:
[tex]g(x) = f(\frac xk)[/tex]
In this case, [tex]k = 5[/tex]
So, we have:
[tex]g(x) = f(\frac x5)[/tex]
Calculate [tex]f(\frac x5)[/tex]
[tex]f(\frac x5) = |\frac x5|[/tex]
Hence, the function of g(x) is
[tex]g(x) = |\frac x5|[/tex]

what is the inverse of f(x)? show the work
f(x)+3x+5
Answer:
[tex]f^-^1(x)=\frac{1}{3}x-\frac{5}{3}[/tex]
Step-by-step explanation:
To solve for the inverse, we need to switch the variables and solve for y.
Note that f(x) is the same as y or in other words, the output.
f(x) = 3x + 5
y = 3x + 5
~Switch variables
x = 3y + 5
~Subtract 5 to both sides
x - 5 = 3y
~Divide 3 to everything
1/3x - 5/3 = y
~Flip
y = 1/3x - 5/3

Rena is building a 1 : 180 scale model of a real castle. Her model has a rectangular base that is 333 feet wide and 444 feet long.
What is the area of the base of the actual castle in square feet?
Answer:
26,613,360 ft^2
Step-by-step explanation:
333 feet wide and 444 feet long
333 ft x 444 ft
147,852 ft^2
147,852 = the 1 in the 1:180 ratio, so...
147,852 x 180 = 26,613,360 ft^2

Hailey is putting up a fence in the shape of an isosceles triangle in her backyard. The fence has side lengths as shown, where x represents the number of feet in each fence section. The perimeter of the fence can be covered using 8 total fence sections represented by the expression 8x. If fencing costs $6.50 a foot, what would be the total cost of the fence?
Answer: The total cost would be $780.00
The expression for the total cost of fencing is $52x , where x is a variable representing the number of feet in one section.
What is an expression in one variable?An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .
Given that number of feet in one fence section be x
No of feet in 8 such fence section = 8x
Given , Perimeter = 8 fence sections = 8x feet
Cost of fencing of one foot = $6.50
Cost of fencing 8x feet = 8x * 6.50
Therefore , the total cost of the fencing can be given by = 8x*6.50
= $ 52 x
Thus, the expression for the total cost of fencing is $52x
