Answer:

D. 20

Step-by-step explanation:

The line of best fit for the equation is:

[tex]y = 3x - 4[/tex]

When x = 8

We have to find y. So

[tex]y = 3*8 - 4 = 24 - 4 = 20[/tex]

So the correct answer is given by option D.

Answer:

yea i know bitly is a scam

Step-by-step explanation:

Given,

Side = 7 cm

We know that,

Volume of a cube = side³

So, volume of Harry's cube

= (7 cm)³

= 343 cm³

Hi, here's a quick explanation;

if the given length is 7, and your object is a cube,

you'd cube 7,

which is =  7³

aka:   7 × 7 × 7

therefore,

Hope this helps you out!!    :D

Answer:

Step-by-step explanation:

Use the Law of Cosines:

c^2 = a^2 + b^2 - 2ab*cos C becomes

7^2 = 11^2 + 13^2 - 2(11)(13)cos C.

Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.

Step-by-step explanation:

Answer:

Part A: yes

Part B: yes

Part C: yes

Step-by-step explanation:

Part A:

77² + 420² = 427²

5,929 + 176,400 = 182,329

182,329 = 182,329

---------------------------------------------------------

Part B:

279² + 440² = 521²

77,841 + 193,600 = 271,441

271,441 = 271,441

----------------------------------------------------------

Part C:

39² + 760² = 761²

1,521 + 577,600 = 579,121

579121 = 579,121

Answer: the original cost of the item is 90$

Step-by-step explanation:

30% off of the item = 27$

27 dollar is 30% of the item

thus 27 = 0.30X

0.30X = 27

time both side by 10

3X = 270

270/3 = 90

Answer:

62 degrees

Step-by-step explanation:

HJ is a line which means its 180 degrees if HIL is 118 degrees then LIJ is 62 degrees and due to the lines being parallel then MLN is also 62 degrees

So, we know that ∠HIL = 118, and we also know that a line is 180 degrees. This means that ∠HIL +∠JIL = 180. We can use simple arithmetic and substitution to find that 180-118= 62, so ∠JIL = 62.

We have another line, Line N, so we know that the line is equal to 180 as well! Because ∠JIL and ∠ILM are both on this line, ∠JIL +∠ILM = 180. ∠JIL = 62, so 180 - 62 = 118.

Lastly, Line N is still equal to 180, so ∠ILM + ∠MLN = 180. In this case, we have 180-118=62, so ∠MLN = 62.

Or, using theorems, there is an easier way to do this.

The corresponding angles theorem tells us that "If a transversal intersects two parallel lines, the corresponding angles are congruent." So, we can see that both ∠MLN and ∠JIL are corresponding so they are congruent. First, however, we need to find ∠JIL, and if we look at our work from above, we see that ∠JIL = 62. Since ∠JIL and ∠MLN are congruent, or the same, ∠MLN is also 62.

Answer:

72π

Step-by-step explanation:

Please see the attached image. r is the radius and h is the height.

The radius is half the diameter, so it is 6/2=3.

The height is given, 8.

Knowing the radius is 3 and the height is 8, all we need to do is plug it into the formula.

Volume=π3^2*8

=72π

or

≈226.19

Answer:

x = 12    y = 24     z = 12[tex]\sqrt{3}[/tex]

Step-by-step explanation:

you are correct.  x = 12

The dotted line has a length of 12 also

The dotted line is the shorter leg of the 30-60-90 triangle.

So, z = 12[tex]\sqrt{3}[/tex] and y = 24

Answer:

The nth bounce a sub n is 0.25 (a sub n-1)

0.625 cm

  Recursive formula of the sequence → [tex]T_n=10240(\frac{1}{4})^{n-1}[/tex]

  Explicit formula of the sequence → [tex]T_1=10240, \\T_{n+1}=T_n(0.25)[/tex]

  Height of the ball after 8th bounce will be 0.625 cm.

        Sequence will be the geometric sequence and the explicit formula

        of the sequence will be,

        [tex]T_n=ar^{n-1}[/tex]

        Here, [tex]a=[/tex] First term

        [tex]r=[/tex] Common ratio

        [tex]n=[/tex] Number of terms

        [tex]a=[/tex] First term

        [tex]T_{n+1}=T_n(r)[/tex]

From the table attached,

There is common ratio between the successive term and previous term under the column (height after the bounce) is,

[tex]\frac{T_2}{T_1}=\frac{2560}{10240}=\frac{1}{4}[/tex]

[tex]\frac{T_3}{T_2}=\frac{640}{2560}=\frac{1}{4}[/tex]

Therefore, height of the ball after each bounce will represent a geometric sequence.

Explicit formula of a geometric sequence will be given by the expression,

[tex]T_n=10240(\frac{1}{4})^{n-1}[/tex]

Recursive formula for the sequence will be,

[tex]T_1=10240[/tex]

[tex]T_{n+1}=T_n(\frac{1}{4})[/tex]

By using recursive formula,

Height of the ball after 8th bounce,

[tex]T_8=10240(\frac{1}{4})^{8-1}[/tex]

    [tex]=10240(0.25)7[/tex]

    [tex]=0.625[/tex] cm

      Therefore, explicit formula to represent the height of the ball will be [tex]T_n=10240(\frac{1}{4})^{n-1}[/tex]recursive formula will be, [tex]T_1=10240\\T_{n+1}=T_n(0.25)[/tex]

       And height of the ball after 8th bounce will be 0.625 cm.
