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

Barb is making a bead necklace. She strings 1 white bead, 3 blue bead, then 1 white bead, and so on. Write the numbers for the the eight beads that are white. What is the rule for the pattern?
Answer:
1,5,9,13,17,21,25,29
Step-by-step explanation:
From the information given.
Let represent the number of white beads with x and the number of blue beads with y. So, the beads can be illustrated as:
bead color
1 x
2 y
3 y
4 y
5 x
6 y
7 y
8 y
Suppose n denotes the no. of beads that are white.
Then the subsequent no is ( n + 4).
Since the first number n = 1
Then the subsequent numbers will follow the pattern of adding 4 to the number.
i.e.
n = 1 + 4 = 5
n = 5 + 4 = 9
n = 9 + 4 = 13
n = 13 + 4 =1 7
n = 17 + 4 = 21
n = 21 + 4 = 25
n = 25 + 4 = 29
Thus, the number for the first eight beads that are white are:
1,5,9,13,17,21,25,29
The pattern shows odd numbers only.

[B] S, = 16536
[C] Sy = 15631
D] S, = 31256
[E] None of these
Understanding:
The sum of a geometric series is, [tex]a+ar+ar^2+ar^3+...[/tex], with a being the start point and r is the common ratio. We can also use the following formula to make life easier [tex]S_n=a\frac{1-r^n}{1-r}[/tex], a is your start point, r is the common ratio, and n is the number of terms, which in our case is S7.
Solution:
Our start point is 1, [tex]a=1[/tex],
The common ratio is 5, [tex]r=5[/tex],
And finally, the number of terms is 7, [tex]n=7[/tex].
[tex]S_n=a\frac{1-r^n}{1-r} \\=(1)\frac{1-(5)^{(7)}}{1-(5)} \\=\frac{1-78125}{1-5} \\=\frac{-78124}{-4}\\=19531[/tex]

13=4k+9 can someone plz help me figure this out it is killing me
Answer:
k = 1
Step-by-step explanation:
so we basically have to solve for k
13 = 4k + 9
subtract 9 from both sides
4 = 4k
divide both sides by 4 to get k by itself
4/4 = 1
4k / 4 = 1k = k
1 = k

Which is a better deal and why? And find the unit rate for both if you wanna help pls
Unit rate = cost / quantity
Lower unit rate is better deal.
3.50/10 = 0.35

The original 10 for 3.50 is the better deal.
Answer:
As we know that
Unit = Rate/Quantity
[tex] \tt \: \dfrac{3.50}{10} = 0.35[/tex]

Martha and 4 friends attended a volleyball game. Admission was $3.50 per person. They all got snacks that were $2.50 each and a drink that was $1.50. On the way home they stopped at Starbucks for a frappucino that cost $4.75 per person. Martha paid for everything. How much did she pay?
Answer:
$61.25
Step-by-step explanation:
Given that:
There are 5 persons (Martha and 4 other friends)
Fee for admission for each person = $3.50
Price for snacks for each person = $2.50
Price for drinks for each person = $1.50
Price for frappucino for each person = $4.75
All the money was paid by Martha.
To find:
Total money paid by Martha.
Solution:
First of all, let us find the total cost for one person.
Total cost for one person = $3.50 + $2.50 + $1.50 + $4.75 = $12.25
There are a total of 5 persons.
Therefore total cost = $12.25 [tex]\times[/tex] 5 = $61.25
Total money paid by Marth = $61.25

Each triangle weighs 2.5 pounds,each circle weighs 3 pounds, and x represents the weight of each square. Select all equations that represent the hanger.
Step-by-step explanation:
x+x+x+x+2.5(2)+3(2)=x+x+2.5+3(3)
4x+5+6=2x+2.5+9
4x+11=2x+11.5
-11 -11
4x=2x+0.5
-2x -2x
2x=0.5
x=0.25
The equation that can be used to represent the hanger is x + x + x + x + 11 = x + x + 11.5, and 4x + 2.5 + 2.5 + 6 = 2x + 2.5 + 3 + 3 + 3
Given:
Each triangle = 2.5 pounds
Each circle = 3 pounds
Each square = x pounds
The hanger has two sides
Side 1:
squares = 4
Triangle = 2
Circle = 2
Side 2:
Squares = 2
Triangle = 1
Circle = 3
The equation:
side A = side B
4(x) + 2(2.5) + 2(3) = 2(x) + 1(2.5) + 3(3)
4x + 5 + 6 = 2x + 2.5 + 9
4x + 11 = 2x + 11.5
x + x + x + x + 11 = x + x + 11.5
Therefore, equation that can be used to represent the hanger is x + x + x + x + 11 = x + x + 11.5, and 4x + 2.5 + 2.5 + 6 = 2x + 2.5 + 3 + 3 + 3

Answer:
The height of right circular cone is h = 15.416 cm
Step-by-step explanation:
The formula used to calculate lateral surface area of right circular cone is: [tex]s=\pi r\sqrt{r^2+h^2}[/tex]
where r is radius and h is height.
We are given:
Lateral surface area s = 236.64 cm²
Radius r = 4.75 cm
We need to find height of right circular cone.
Putting values in the formula and finding height:
[tex]s=\pi r\sqrt{r^2+h^2}\\236.64=3.14(4.75)\sqrt{(3.75)^2+h^2} \\236.64=14.915\sqrt{(3.75)^2+h^2} \\\frac{236.64}{14.915}=\sqrt{14.0625+h^2} \\15.866=\sqrt{14.0625+h^2} \\Switching\:sides\:\\\sqrt{14.0625+h^2} =15.866\\Taking\:square\:on\:both\:sides\\(\sqrt{14.0625+h^2})^2 =(15.866)^2\\14.0625+h^2=251.729\\h^2=251.729-14.0625\\h^2=237.6665\\Taking\:square\:root\:on\:both\:sides\\\sqrt{h^2}=\sqrt{237.6665} \\h=15.416[/tex]
So, the height of right circular cone is h = 15.416 cm
The equation of the line that contains diagonal HM is y = 2/3 x + 7.
What is the slope of the line that contains diagonal OE?
Answer:
The slope of the line that contains diagonal OE will be = -3/2
Step-by-step explanation:
We know the slope-intercept form of the line equation
y = mx+b
Where m is the slope and b is the y-intercept
Given the equation of the line that contains diagonal HM is y = 2/3 x + 7
y = 2/3 x + 7
comparing the equation with the slope-intercept form of the line equation
y = mx+b
Thus, slope = m = 2/3
We know that the diagonals are perpendicular bisectors of each other.As we have to determine the slope of the line that contains diagonal OE.
As the slope of the line that contains diagonal HM = 2/3
We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line that contains diagonal
OE will be = -1/m = -1/(2/3) = -3/2
Hence, the slope of the line that contains diagonal OE will be = -3/2

Today only, every sweatshirt is $4.25 less than normal price. Right now if you buy 5 sweatshirts, the total cost will be $106.25. What's the normal price of the sweatshirt?
Answer:
Step-by-step explanation:
The normal price of the sweatshirt will be $21.50 because if you divide $78.75 by 5 you get $15.75 for each sweatshirt then you add the $5.75 with will make the original price $21.50
Answer:
25.50
Step-by-step explanation:
You take 106.25 divided by 5 and you get the marked down price of one sweatshirt which is 21.25 so then you add 4.25 to that price and get 25.50.

Which ratio is not equivalent to 15:18?
A. 60:72
B. 35:42
C. 90:105
D.25:30
Answer:
The ratio 90: 105 is not equivalent to 15: 18 ⇒ C
Step-by-step explanation:
Let us simplify the given ratio to its simplest form first
∵ The ratio is 15: 18
∵ 15 and 18 have a common factor 3
→ Divide each term of the ratio by 3
∴ [tex]\frac{15}{3}[/tex] : [tex]\frac{18}{3}[/tex] = 5: 6
∴ The simplest form of ratio 15: 18 is 5: 6
Let us find which choice will not give us the same ratio 5: 6
∵ 60: 72 have a common factor 12
→ Divide each term of the ratio by 12
∵ [tex]\frac{60}{12}[/tex] : [tex]\frac{72}{12}[/tex] = 5: 6
∴ The simplest form of ratio 60: 72 is 5: 6
∴ The ratio 60: 72 is equivalent to 15: 18
∵ 35: 42 have a common factor 7
→ Divide each term of the ratio by 7
∵ [tex]\frac{35}{7}[/tex] : [tex]\frac{42}{7}[/tex] = 5: 6
∴ The simplest form of ratio 35: 42 is 5: 6
∴ The ratio 35: 42 is equivalent to 15: 18
∵ 90: 105 have a common factor 15
→ Divide each term of the ratio by 15
∵ [tex]\frac{90}{15}[/tex] : [tex]\frac{105}{15}[/tex] = 6: 7
∴ The simplest form of ratio 90: 105 is 6: 7
∴ The ratio 90: 105 is not equivalent to 15: 18

∠A and \angle B∠B are vertical angles. If m\angle A=(5x-2)^{\circ}∠A=(5x−2) ∘ and m\angle B=(3x+12)^{\circ}∠B=(3x+12) ∘ , then find the value of x.
Answer:
x = 7
Step-by-step explanation:
From the above question, we are told that:
∠A and ∠B vertical angles.
It is important to note that vertical angles are equal to each other
Hence:
∠A = ∠B
From the question,
∠A = (5x−2)°
∠B = (3x+12)°
Hence:
(5x−2)°= (3x+12)°
5x - 2 = 3x + 12

5x - 3x = 12 +2
2x = 14
