[(√4 + 3)2 – 9] / (√9 – 1)3 * 2

Answers

Answer 1
Answer:

Answer:

(1)/(12)

Step-by-step explanation:

((√(4) + 3)2 - 9)/( (√(9) - 1)3 * 2)=((2+3)2-9)/((3-1)6)=(10-9)/(2*6)=(1)/(12)

Find the 12th term in the sequence: 1/16, -1/8, 1/4

Answers

Answer:

Step-by-step explanation:

hello :

the sequence is geometric because : (1/4)/(-1/8) = (-1/8)/(1/16)=-2   = r

the nth term is :  An =A1 × r^(n-1)

a common ratio is : r  and A1 the first term

in this exercice :   r =2         A1 = 1/16

when : n =12 you have the  12rd term  A12

A12 = 1/16 × 2^(12-1)  = 1/16 × 2^(11)

Find the volume o the sphere.

Answers

Answer:

The volume of sphere is 267.95 units³.

Step-by-step explanation:

Given that the formula of volume of sphere is V = 4/3×π×r³ where r represents radius. Then, you have to substitute the values into the formula :

v =  (4)/(3)  * \pi *  {r}^(3)

let \: r = 4

v =  (4)/(3)  * \pi *  {4}^(3)

v =  (4)/(3)  * \pi * 64

v =  (256)/(3)  * 3.14

v = 267.95 \:  {units}^( 3)

V=4/3πr^3
= 4/3 x π x 4^3
= 268.08
= 85.33 π
~ 300 units ^3

I am probably just really dumb, but I don't understand the concept. The question is: -42v+33<8v+91. I am supposed to solve the inequality for v. Please give an explanation and not just an answer, I would really like to know how to do this.

Answers

-42v +33 <8v +91

Move all terms with V to the left side by subtracting 8V from both sides.

-50v +33 < 91

Now get the term with V all by itself by subtracting 33 from each side:

-50v<58

Solve for V by dividing both sides by -50  ( when dividing an inequality by a negative number you also need to reverse the direction of the inequality sign).

v >58/-50

Reduce the fraction and relocate the negative sign:

V >-29/25


The speed of light is about 1.86×10^5 miles per second. The star Sirius is about 5.062×10^13 miles from Earth. About how many seconds does it take light to travel from Sirius to Earth? Write your answer in scientific notation, rounded to the nearest hundredth.

Answers

The number of seconds it takes light to travel from Sirius to Earth is 2.72*10^(8).

Given that, the speed of light is about 1.86×10^5 miles per second. The star Sirius is about 5.062×10^13 miles from Earth.

We need to find out how many seconds it takes light to travel from Sirius to Earth.

What is scientific notation?

To determine the power or exponent of 10, let us understand how many places we need to move the decimal point after the single-digit number.

  • If the given number is multiples of 10 then the decimal point has to move to the left, and the power of 10 will be positive.
  • If the given number is smaller than 1, then the decimal point has to move to the right, so the power of 10 will be negative.

Let the number of seconds it takes light to travel from Sirius to Earth be n seconds

Now, the proportion=(1.86*10^(5))/(1) =(5.062*10^(13))/(n)

n=(5.062*10^(13))/(1.86*10^(5))

n=2.72*10^(13-5)=2.72*10^(8)

Therefore, the number of seconds it takes light to travel from Sirius to Earth is 2.72*10^(8).

Answer:

2.72 × 10^8 seconds

Step-by-step explanation:

1. Organize the given information to help you create the equation:

- Light travels 1.86 × 10^5 miles per 1 second

- Light travels 5.062 × 10^13 miles per n seconds

- Need to solve for n

2. Set up the equation (Make sure that both numerators and both denominators match units, so the seconds are either both on top or both on bottom, NOT switched):

(1.86 * 10^5)/(1) = (5.062 * 10^1^3)/(n)

3. Cross multiply (Multiply the first fraction's numerator by the second's denominator, and vice versa. It doesn't matter what number is on which side of the = sign)

n × (1.86 × 10^5) = 5.062 × 10^13

4. Solve for n by isolating the variable and dividing.

(n (1.86 * 10^5))/(1.86 * 10^5) = (5.062 * 10^1^3)/(1.86 * 10^5)

n = (5.062 * 10^1^3)/(1.86 * 10^5)

n = 2.72 × 10^8 (Make sure to include the unit, seconds)
