alegbra 2 pls help ill give brainliest

Answer:

your answer will be 3.4

Step-by-step explanation:

n=number of terms

{6,5,10,11,13}=5

also ∑(x-x)^2=46

[tex]S=\sqrt{\frac{1}{5-1} *46} =[/tex]

[tex]\sqrt{\frac{46}{4} }=\sqrt{11.5} \\\\S=3.4[/tex]

hope it helps

have a great day!!

Answer:

6x + 11x - 10

Step-by-step explanation:

So in order to solve this expression, we have to distribute the numbers in each set of parenthasis

Step 1 : break down each mini-espression you're solving

(2x+5)(3x-2)

each term is multiplied by both terms in the other set of parenthasis.

(2x · 3x) + (2x · -2) + (5 · 3x) + (5 · -2)

Step 2 : Solve each idividual piece

(2x · 3x) = 6x²

(2x · -2) = -4x

(5 · 3x) = 15x

(5 · -2) = -10

Step 3 : Put it all together amd simplify

6x² - 4x + 15x - 10

6x² + 11x - 10

Answer:

2 and 4

Step-by-step explanation:

Consider a perfect square smaller than 8 and a perfect square larger than 11

That is 4 and 16, then

[tex]\sqrt{4}[/tex] < [tex]\sqrt{8}[/tex] and [tex]\sqrt{11}[/tex] < [tex]\sqrt{16}[/tex] , that is

Following are the responses to the give question:

Step-by-step explanation:

The [tex]f(x) = x^2 + 4[/tex] model is developed in the interval [tex](-2, 2)[/tex] total equal in a between such a range[tex]= 5[/tex].

Its right endpoint of every rectangle is separated onto n equal parts by the height [tex]= \frac{5}{n}.[/tex]

Height of endpoint [tex]= \frac{5}{n}[/tex] of the k rectangles therefore, the height of the kth rectangle = First rectangle height + K rectangle height

[tex]= -2 +k \times \frac{5}{n}\\\\[/tex]

Answer:

The price per cheese stick was increased by 150%.

The amount of cheese sticks per $1.00 has decreased by 60%.

Step-by-step explanation:

The price per cheese stick was $0.10

The current price per cheese stick is $0.25

That means the price per cheese stick was raised by 150%.

That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.

Step-by-step explanation:

Answer:

9/40

Step-by-step explanation:

Tan of an angle equals the length of the side opposite the angle divided by the length of the leg adjacent to the angle. Thus, for angle C, AB is opposite it, which is 9, and although both CA and CB are adjacent, adjacent typically refers to the leg, not the hypotenuse, so we want CB, which is 40. Opposite/Adjacent = 9/40

Incomplete question. The missing options read;

a. Kate surveys every 8th student from a roster of the choir members.

b. Kate surveys the football team.

c. Kate surveys seventh-grade students.  

d. Kate surveys every 4th student entering the school.

Answer:

d. Kate surveys every 4th student entering the school.

Step-by-step explanation:

Interestingly, after careful examination of all the listed sampling methods, none except option d would best produce a representative sample of the population.

This is because;

in the first, second, and third option, none of them evenly represents the entire school population; meaning it fails to produce a representative sample of the population.

However, if Kate surveys every 4th student entering the school, then chances of getting a representative sample of the entire school population are very likely; as different grade level students would likely be entering into the school when the survey activity is taking place.

Step-by-step explanation:

x 12 = 12.

x 6 = 12.

x 4 = 12.

x 3 = 12.

Answer:

7.3

Step-by-step explanation:

Order of operations rules require that any work inside parentheses be done first.  Thus,

(4 + 2) - 1 + (2.3) becomes 6 - 1 + 2.3

This, in turn, becomes 5 + 2.3, and the final result is 7.3.

Answer:

$96

Step-by-step explanation:

 [tex]f(x)= a(1-r)^x[/tex]

a= initial amount

x= time in years

r= decay rate

[tex]f(x)= 1,200(1-0.4)^5[/tex] ≈

[tex]f(x)= 96[/tex]

Answer:

6216

Step-by-step explanation:

This problem deals with exponential growth.

Final value: F

Present (initial) value: P

Rate of growth: r

Time in years = t

[tex] F = P(1 + r)^t [/tex]

[tex] F = 2900(1 + 0.1)^8 [/tex]

[tex] F = 6216 [/tex]

Answer:

  time to max height: 2.5 seconds

  max height: 104 ft

  range of function: [4, 104]

Step-by-step explanation:

The equation for ballistic motion is ...

  h(t) = -16t^2 +v0·t +h0 . . . . where v0 is the initial upward speed and h0 is the initial height

For the given parameters, the height function is ...

  h(t) = -16t^2 +80t +4

The time for maximum height is ...

  -b/(2a) = -80/(2(-16)) = 2.5 . . . seconds

The maximum height is ...

  h(2.5) = (-16·2.5 +80)(2.5) +4 = 104 . . . feet

The range of the function is from the minimum height (at launch) to the maximum height:

  4 ft ≤ h(t) ≤ 104 ft.

Answer:

200π cm^2

Step-by-step explanation:

Sb = 8^2 π = 64π cm^2

a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm

Sl = 8x17xπ = 136 π cm^2

SA = 136π + 64π =200π cm^2
