a_{n} \:  =  \: 2(a_{n - 1})^{2} \\ a_{1} = 4 \: (given) \\ a_{2} = \: 2(a_{2 - 1})^{2}  \\  = 2(a_{ 1})^{2}   \\  = 2 \times  {4}^{2}  \\  = 32 \\  \\ a_{3} = \: 2(a_{3 - 1})^{2}  \\  = 2(a_{ 2})^{2}   \\  = 2 \times  {32}^{2}  \\  = 2 \times 1024 \\  = 2048

so first 3 terms are

4, 32, 2048

Answer:

The correct answer is option 3

4, 32, 2048

Step-by-step explanation:

It is given that,

a₁ = 4

aₙ = 2(aₙ₋₁)²

<u>To find the second term</u>

we have, aₙ = 2(aₙ₋₁)²

a₁ = 4

a₂ = 2(a₁)² = 2(4)² = 2 * 16 = 32

<u>To find the third term</u>

aₙ = 2(aₙ₋₁)²

a₂ = 32

a₃ = 2(a₂)² = 2(32)² = 2 * 1024 = 2048

Therefore the first three terms of the sequence are,

4, 32, 2048

The correct answer is option 3

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .<span>X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 30/5 = 6.Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 30/-3 = -10.Slope is -5/-3 = 1.66666666666667.<span> Equation in slope-intercept form: y=1.66666666666667*x+-10.</span></span>

Most intruments produce notes across ranges called octaves which are made up of 8 notes how many octaves do 51 notes span?
mojhsa [17]

Answer: 51 notes span 6 octaves.

Step-by-step explanation:

The word "octave" is a Latin word that means "eight".

In an instrument, Each octave is made up of 8 musical notes.

If we have 51 notes , the number of octaves can be made in it = \dfrac{51}{8}

=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}

Hence, 51 notes span 6 octaves.

Mike can plow a field in 12 hours and his brother Phil can plow it in 15 hours. How long will it take them to plow it if they us
Korvikt [17]

Answer:

6.66 hours, that is, 6 hours and 40 minutes.

Step-by-step explanation:

If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.

If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.

So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:

(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66

So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.
