What are the solutions of 16p 2 - 64 = 0?

Mathematics
1 answer:
antoniya [11.8K]3 years ago
4 0

Answer:

=2 =−2

Step-by-step explanation:

<em>Common factor</em>

16 2 − 64 = 0

16(2 − 4)= 0

Use the sum-product pattern

16(2−4)=0

16(2 + 2 − 2 − 4) = 0

Common factor from the two pairs

16(( 2 + 2) + (−2 − 4)) = 0

16 ( ( + 2 ) − 2 ( + 2 ) ) = 0

Rewrite in factored form

16 ( ( + 2 ) − 2 ( + 2 ) ) = 0

1 6 ( − 2 ) ( + 2 ) = 0

Create separate equations

16 ( − 2 ) ( + 2 ) = 0

− 2 = 0

+ 2 = 0

Solve / Rearrange and isolate the variable to find each solution

= − 2

= 2

Answer:

Step-by-step explanation:

Cone

Givens

r = 1.5 inches

h = 4 inches

Formula

V = 1/3 pi r^2 h

V = 1/3 3.14 * 1.5^2 * 4

V = 1/3* 3.14 * 2.25 * 4

V = 9.42

Semi sphere

Givens

r = 1.5

Formula

V = 2/3 * pi * r^3

Solution

V = 2/3 * 3.14 * 1.^3

V = 7.065

Total

V = 9.42 + 7.065

V = 16.485

Rounded to the nearest 1/100

V = 16.49

First term:  a(1) = 4; common ratio:  r = 2

Then:

a(n) = 4(2)^(n-1)

Check:  Predict the 4th term using this formula:

a(4) = 4(2)^3 = 4(8) = 32  (correct)

2. Ravi purchased an old house for Rs. 76.5000 and
lorasvet [3.4K]

Answer:

Rs. 924000.

Step-by-step explanation:

Cost of  house = 765000

Additional money spent on it = 115000

Total cost incurred by Ravi = 765000 + 115000 = 880000

Gain  = 5% of total cost

gain in Rs = 5/100 * 880000 = Rs. 44000

Total selling price of house = total cost incurred + profit = 880000+ 44000

Total selling price of house = Rs. 924000

Thus, Ravi got  Rs. 924000.
