Let R be the region bounded by the following curves. Use the method of your choice to find the volume of the solid generated when R is revolved about the​ x-axis. y = 6x^2 & y = 28 - x^2

Answers

Answer 1

Answer:

V = 7168π /3  

Step-by-step explanation:

R ( region ) bounded by curves ; y = 6x^2 , y = 28 - x^2

determine the volume of the solid generated when R is revolved about the x-axis

 Volume = 7168π /3    

attached below is the remaining part of the detailed solution to the problem above

Given that :

y = 6x^2----- ( 1 )   ,  y = 28 - x^2 ------ ( 2 )

equate  ( 1 ) and ( 2 )

6x^2 = 28 - x^2

7x^2 = 28

∴ x = √4 = ± 2

Let R Be The Region Bounded By The Following Curves. Use The Method Of Your Choice To Find The Volume

Answers

Answer:

7

Step-by-step explanation:

did the question

The amount of money would be $6,880 in the account after 7 years.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

A = P(1+r/100)ⁿ

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Given data as follows:

p = $5,300

r = 3.8%

A = $6,880

A = P(1+r/100)ⁿ

Substitute the values of p,r, and A in the formula,

6,880 = 5,300(1 + 3.8/100)ⁿ

6,880/5,300 = (1 + 0.038)ⁿ

1.2981 = (1.038)ⁿ

n = 6.9954

Rounded to the nearest digit, and we get

n = 7

Therefore, the amount of money would be $6,880 in the account after 7 years.

whats 4 x 2/3 as a multiple of a unit fraction

Answers

4 times 2/3= 8/3= 2 2/3

I hope this helps!

The expression 4 x 2/3 as a multiple of a unit fraction is 8/3, which is equal to (1/3) x 8.

What is an expression?

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.

To express 4 x 2/3 as a multiple of a unit fraction, we need to find a fraction that can be multiplied by a whole number to give us 4 x 2/3.

First, we can simplify 2/3 by dividing both the numerator and denominator by their greatest common factor, which is 1. This gives us:

2/3 = 2 ÷ 1 / 3 ÷ 1 = 2/3

Next, we can multiply 4 by 2/3 to get:

4 x 2/3 = 8/3

To express 8/3 as a multiple of a unit fraction, we can use the fact that any fraction can be expressed as a sum of unit fractions. We can start by expressing 1/3 as a unit fraction:

1/3 = 1 ÷ 3

Next, we can multiply both the numerator and denominator of 1/3 by 3 to get:

1/3 = 3 ÷ 9

Now we can express 8/3 as a sum of unit fractions:

8/3 = (3/9) x 8 = (1/3) x 8 = 8 ÷ 3

Therefore, 4 x 2/3 as a multiple of a unit fraction is 8/3, which is equal to (1/3) x 8.
