Answer:

aₙ = - 30n + 9

Step-by-step explanation:

You can tell this is an arithmetic sequence, as there is a difference of 30 between each value. Therefore the equation we will use here is aₙ = a₁ + (n - 1)d.

aₙ = a₁ + (n - 1)d

= - 21 + (n - 1) * - 30

= - 21 - 30n + 30

= - 30n + 9

Your solution would be option d. aₙ = - 30n + 9

Answer:

95.49 g

Step-by-step explanation:

D = m/v

Looking for mass so isolate m to form equation format

D × V = m

Plug in numbers

.7892g/mL × 121.0 mL = 95.4932 g

Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.

Round to sig figs

Both original numbers hold 4 sig figs

Answer:

1 + i[tex]\sqrt{5}[/tex], 1 - i[tex]\sqrt{5}[/tex]

Step-by-step explanation:

A quadratic function is    f(x) = a[tex]x^{2}[/tex] + bx + c

Your function with the given values is   f(x) = 2[tex]x^{2}[/tex] - 4x + 12

To solve a quadratic function, you can use the quadratic formula  

(-b +/- [tex]\sqrt{b^{2} - 4ac}[/tex]) / 2a

Fill in with your given values.

(4 +/- [tex]\sqrt{(-4^{2} - 4 (2) (12)}[/tex] ) / 2(2)

Simplify

(4 +/- [tex]\sqrt{16 - 96}[/tex]) / 4

(4 +/- [tex]\sqrt{-80}[/tex] ) / 4

Because there is a negative number under the square root making it an imaginary number put an i by it.

(4 +/- i[tex]\sqrt{80}[/tex]) / 4

80 is divisible by 16, a perfect square. 80 / 16 = 5

(4 +/- 4i[tex]\sqrt{5}[/tex]) / 4

Divide by 4

1 +/- i[tex]\sqrt{5}[/tex]

Your teacher may want you to list your radical without the i and just as [tex]\sqrt{-5}[/tex], so keep that in mind.

Don't forget to list it both as addition and subtraction.

Answer:

x = 11 and H = 39°

Step-by-step explanation:

Complementary angles add up to 90 degrees, so angles G and H will add up to 90 degrees.

Create an equation by adding the expressions together and setting it equal to 90.

(6x - 15) + (3x + 6) = 90

Solve for x by adding like terms first:

9x - 9 = 90

Isolate x and solve:

9x = 99

x = 11

Then, find H by plugging in 11 as x into the expression:

3x + 6

3(11) + 6

33 + 6

= 39

So, x = 11 and H = 39°

The value of x is 11 and the value of H is 39.

Given,

G= (6x-15)°

H= (3x+6)° are complementary angles.

We need to find the value of x and H

What are complementary angles?

If the sum of two angles is 90 degrees the angles are called complementary angles.

We have,

G= (6x-15)°

H= (3x+6)° are complementary angles.

We can write it as,

(6x-15)° + (3x+6)° = 90°

6x - 15 + 3x + 6 = 90

9x - 9 = 90

9x = 90 + 9

9x = 99

x = 99/9

x = 11

Find the value of x and H.

x = 11.

H = 3x + 6

   = 3 x 11 + 6

   = 33 + 6

   = 39

H = 39

Thus the value of x is 11 and the value of H is 39.

Step-by-step explanation:

Answer:

A. x+30

B. x+35

Step-by-step explanation:

A. Daniel

Since "Daniel is 30 cm taller than Katie" and "Katie's height is x cm", the expression will be x+30

B. Juli (sorry I can't type the full name due to Brainly system)

Since "Juli is 5 cm taller than Daniel" and Daniel is (x+30) cm, the expression will be (x+30)+5=x+35

Given:

Consider the file sizes (in  megabytes) for 18 randomly selected files on  Gabriel's mp3 player are shown in the below figure.

To find:

The outliers in the  distribution.

Solution:

We have, the given data set

2.4, 2.7, 1.6 , 1.3 , 6.2, 1.3, 5.6, 1.1, 2.2, 1.9, 2.1, 4.4, 4.7, 3.0, 1.9, 2.5, 7.5, 5.0

Arrange the data in ascending order.

1.1, 1.3, 1.3, 1.6, 1.9, 1.9, 2.1, 2.2, 2.4, 2.5, 2.7, 3.0, 4.4, 4.7, 5.0, 5.6, 6.2, 7.5,

Divide the data in 4 equal parts.

(1.1, 1.3, 1.3, 1.6), 1.9, (1.9, 2.1, 2.2, 2.4),( 2.5, 2.7, 3.0, 4.4), 4.7, (5.0,5.6, 6.2, 7.5)

It is clear that,

[tex]Q_1=1.9[/tex]

[tex]Q_3=4.7[/tex]

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=4.7-1.9[/tex]

Step-by-step explanation:

Answer:

One fruit kabob and one smoothie

Two fruits kabobs and two smoothies

Three fruit kabobs and one smoothie

One fruit kabob and two smoothies

Explanation:

In this situation, the basic combination John can afford is simply to buy one fruit kabob and one smoothie ( $1.75 + $ 2.50 = $4.25) because he wants at least one unit of each item. Additionally, it is possible to add more units of each item to create new combinations or possibles, just make sure they do not total more than 9 dollars, which is the money John has. Here are some of the possible combinations:

Two fruit kabobs and two smoothies

Fruit kabobs: $1.75 x 2 = $3.5

Smoothies: $ 2.50 x 2 = $5

Total: $8.5

Three fruit kabobs and one smoothie

Fruit kabobs: $1.75 x 3 = $5.25

Smoothie: $2.50

Total: $7.75

One fruit kabob and two smoothies

Fruit kabob: $1.75

Smoothies: $2.50 x 2 = $5

Total: $6.75

Hi!

Your answer should be: 3/c, "c= (5)($7)"

Reason being:

A: it only has the number of tickets, so that wouldn't make sense.

B: It has both numbers, but, were not adding, because the tickets cost $7 EACH, so only adding them wouldn't give you the right answer.

C: They are multiplying 5x$7, which is correct because  each ticket is $7, and she is trying to buy 5, so 5x$7=c is correct.

D: like A, they only have one part of the problem, so it wouldn't make sense.

Hope this helps!

Yours truly,

Answer:

I did this in a test so the answer is the third one. i already knew the answer was the third one.

Step-by-step explanation:

Lets check all of em first.

c = 5

(c) cant equal five because (c) is the total cost for tickets and if she bought 5

and each of them is $7  it cant be 5 thes goes same for the other-  c = $7

Now for c = 5 + $7 Clearly you cant find out the total cost for 5 tickets using addition.

therefore, the right answer is c = (5) ($7)
