Complete the statements about the key features of the graph of f(x) = x5 – 9x3.
As x goes to negative infinity, f(x) goes to ________ infinity, and as x goes to positive infinity, f(x) goes to _______ infinity.
Answer:
Negative and positive
Step-by-step explanation:
Complete the statements about the key features of the graph of f(x) = x5 – 9x3.
As x goes to negative infinity, f(x) goes to "NEGATIVE" infinity, and as x goes to positive infinity, f(x) goes to "POSITIVE" infinity.
The complete statement is:
As x goes to negative infinity, f(x) goes to negative infinity, and as x goes to positive infinity, f(x) goes to positive infinity
The function is given as:
[tex]f(x) = x^5 - 9x^3[/tex]
Set x to 2
So, we have:
[tex]f(2) = 2^5 - 9(2)^3[/tex]
[tex]f(2) = -40[/tex]
Set x to 5
[tex]f(5) = 5^5 - 9(5)^3[/tex]
[tex]f(5) = 2000[/tex]
Notice that, as the value of x increases from 2 to 5, the function increases from -40 to 2000
Hence, the texts that complete the blanks are (a) negative and (b) positive, respectively

James invested $4,000 at 5% interest per year; how long will it take him to earn $200 in simple interest?
Answer:
It takes 1 year.
Step-by-step explanation:
You have to apply simple interest formula, I = (P×R×T)/100 where I represent interest amount, P is principle, R is interest rate and T is number of years :
[tex]I = \frac{PRT}{100} [/tex]
[tex]200 = \frac{4000 \times 5 \times T}{100} [/tex]
[tex]20000 = 20000T[/tex]
[tex]T = 1[/tex]
We, know that :
[tex] \underline{\boxed{\sf Interest \: amount = \dfrac{Principal \times Rate \times Time}{100}}}[/tex]
[tex] \underline{\boxed{\sf I = \dfrac{P \times R \times T}{100}}}[/tex]
By putting values, we have
[tex] \sf : \implies 200 = \dfrac{4000 \times 5 \times T}{100}[/tex]
[tex] \sf : \implies 200 \times 100 = 20000 \times T[/tex]
[tex] \sf : \implies 20000 = 20000 \times T[/tex]
[tex] \sf : \implies \cancel{\dfrac{20000}{20000}} = T[/tex]
[tex] \sf : \implies 1 = T[/tex]
[tex] \underline{\boxed{\sf T = 1 \: year}}[/tex]
It takes 1 year for him to earn $ 200 in simple interest.

Alina and Asim share Rs 210 in the ratio 2:5. How much money did each of them get?
Answer:
Step-by-step explanation:
Alina=2x---eq(1)
Asim=5x----eq---(2)
So,we get
2x+5x=210
7x=210
x=30
Now,Putting '30' in eq 1 and eq 2
2*30=60
5*30=150
Therefore Alina got 60 Rs while Asim got 150 Rs
Braulio and Alejandro are siblings. Three years from now, Braulio will be 3 times Alejandro's present age. At that time, Alejandro will then be half as old as Braulio. How old are Braulio and Alejandro? Show all work and circle your final answers
Answer: Braulio is 15 years old, and Alejandro is 6 years old.
Step-by-step explanation:
Let's define:
B = Age of Braulio
A = Age of Alejandro.
"Three years from now, Braulio will be 3 times Alejandro's present age"
We can write this as:
B + 3 = 3*A
"At that time, Alejandro will then be half as old as Braulio"
A + 3 = (B + 3)/2
Then we have a system of equations:
B + 3 = 3*A
A + 3 = (B + 3)/2
To solve this, we first need to isolate one of the variables in one of the equations.
Let's isolate A in the second equation:
A = (B + 3)/2 - 3
Now we can replace this in the other equation to get:
B + 3 = 3*A
B + 3 = 3*((B + 3)/2 - 3)
B + 3 = (3/2)*B + 9/2 - 9
Now let´s move all the terms with B to the left side, and the other terms to the right side.
B - (3/2)*B = 9/2 - 9 - 3
-(1/2)*B = 9/2 - 18/2 - 6/2 = -15/2
B = (-2)*(-15/2) = 15
Braulio is 15 years old.
And from the first equation:
B + 3 = 3*A
15 + 3 = 3*A
18 = 3*A
18/3 = A = 6
Alejandro is 6 years old.

Luiza starts collecting rare coins. In the first month of her collection, she has 25 coins. Each month since then, she has added 2 coins to her collection. How many coins will she have after 2 years?
Answer: 71 coins
Step-by-step explanation:
First and foremost, we should note that:
12 months = 1 year
2 years = 12 × 2 = 24 months
Since she has 25 coins in her first month and adds 2 coins to her monthly collections, this means that she has 23 more months. This can be expressed as:
= 25 + 2x
where, x = number of months
= 25 + 2(23)
= 25 + 46
= 71 coins
She will have 71 coins after 2 years.

What is the slope between these two points? (-5, 2) and (2,8). You must show your work for this problem. *
Answer:
6/7
Step-by-step explanation:
Given the points :
(-5, 2) and (2, 8)
Slope can be obtained by using the relation :
(y2 - y1) / (x2 - x1)
From the points given :
x1 = - 5 ; y1 = 2 ; x2 = 2 ; y2 = 8
(8 - 2) / (2 - (-5))
(8 - 2) / (2 + 5)
6 / 7
Hence, slope between the two points = 6/7

Aaron contributes $3,000 annually toward an IRA. A projected annual return is 7.2%. What is the future value in 5 years?
$15,000.00
$17,321.20
$41,666.67
$108,000.00
Answer:
FV= $17,321.20
Step-by-step explanation:
Giving the following information:
Annual deposit (A)= $3,000
Number of periods (n)= 5 years
Interest rate (i)= 7.2% = 0.072
To calculate the future value (FV), we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {3,000*[(1.072^5) - 1]} / 0.072
FV= $17,321.20

identify the domain and range of the function input 1,3,5,7 output 8,7,6,5
Answer:
Domain = 1,3,5,7
Range = 8,7,6,5
Step-by-step explanation:
We need to identify the domain and range of the function: input 1,3,5,7 output 8,7,6,5
Domain of function:
For any function domain is set of input values.
Range of function:
For any function range is set of output values.
So, for the given function we have : input 1,3,5,7 output 8,7,6,5
Domain = 1,3,5,7 (set of input values is domain of function)
Range = 8,7,6,5 (set of output values is range of function)

What is the x-intercept of the line?
Answer:
- 1
Step-by-step explanation:
y = mx + b ( "m" is slope and "b" is y-intercept )
The equation of a given line is
y = - 2x - 2
Coordinates of x-intercept are ( x, 0 ) ⇒ 0 = - 2x - 2 ⇒ x = - 1
The x-intercept of the line is ( - 1 )
Classity each sequence as arithmetic, geometric, or neither by dragging it into the correct box
Answer:
✔️The arithmetic sequence: 16, 11, 6, 1, -4. . .
✔️The Geometric Sequence: ⁵/9, ⁵/3, 5, 15, 45 . . .
✔️Neither is: ½, 1, 2, 3, 4 . . .
Step-by-step explanation:
In an arithmetic sequence, a constant number called common difference is added or subtracted from each term to get the next successive term in the sequence.
On the other hand, in a geometric sequence, a constant number called common ratio is used to multiply or divide each term to get the next successive term in the sequence.
✔️The arithmetic sequence is:
16, 11, 6, 1, -4. . .
This is because it has a common difference of -5. Thus, 5 is subtracted from each term to get the next successive term.
✔️The Geometric Sequence is:
⁵/9, ⁵/3, 5, 15, 45 . . .
The common ratio is 3. Each term is multiplied by 3 to get the next successive term in the sequence.
✔️Neither is:
½, 1, 2, 3, 4 . . .
This sequence lacks either a common difference or a common ratio.
Find the value
[tex](2x)0[/tex]
[tex] \bf {(2x)}^{0} = 1[/tex]
The rule is that any number raised to the power of 0 equals to 1.
So if 2 or 1,000,000 is raised to the power of 0 it equals 1.
But 0 to the power 0 is undefined!
0 to any positive power is 0, so 0 to the power 0 should be 0. But any positive number to the power 0 is 1, so 0 to the power 0 should be 1. We can't have it both ways. Underlying this argument is the same idea as was used in the attempt to define 0 divided by 0.

Find the values of X and Y.
Given:
A figure.
To find:
The value of x and y.
Solution:
In triangle ADC, all angles are equal, so it is an equilateral triangle.
We know that, all sides of an equilateral triangle are equal.
[tex]AD=AC[/tex] ...(i)
[tex]3x-5=5y-4[/tex] ...(ii)
In triangle ABD,
[tex]\angle BAD=\angle ABD[/tex]
Base angles are equal, so triangle ABD is an isosceles triangle.
[tex]AD=BD[/tex] ...(iii)
Using (i) and (iii), we get
[tex]AC=BD[/tex]
[tex]5y-4=y+12[/tex]
[tex]5y-y=4+12[/tex]
[tex]4y=16[/tex]
Divide both sides by 4.
[tex]y=4[/tex]
Putting y=4 in (ii), we get
[tex]3x-5=5(4)-4[/tex]
[tex]3x-5=20-4[/tex]
[tex]3x-5=16[/tex]
Adding 5 on both sides, we get
[tex]3x=16+5[/tex]
[tex]3x=21[/tex]
Divide both sides by 3.
[tex]x=7/tex]
Therefore, the value of x is 7 and the value of y is 4.

Larry is 8 years older than his sister. Two times Larry's age is five more
than three times his sister's age. How old is Larry now?
Answer:
larry is 19
Step-by-step explanation:
ok, so larry's age is y, his sisters age is x
x + 8 = y
thats the equation for him being 8 years older
now 2y = 3x + 5
his sisters age is 3x + 5 to get larry's age when its doubled
substitute x + 8 in for y
2 (x+8) = 3x + 5
2x + 16 = 3x + 5
16 = x + 5
x = 11
11 + 8 = y
y = 19
