Answer :
Answer: Radius of a solid aluminium sphere is 3.67 cm.
Step-by-step explanation:
4/3 · 2.57³ π · 7,860 = 4/3 · r³ π · 2,700 / : 4/3 π
2.57³ · 7860 = r³ · 2,700
r³ = 2.57³ · ( 7,860 : 2.700 ) = 2.57³ · 2.911111... /∛
r ≈ 2.57 · 1.428 = 3.67 cm
C=100.I used the Pythagorean theorem just in case next time you run into this problem.
Answer:
see explanation
Step-by-step explanation:
(a)
Given
2k - 6k² + 4k³ ← factor out 2k from each term
= 2k(1 - 3k + 2k²)
To factor the quadratic
Consider the factors of the product of the constant term ( 1) and the coefficient of the k² term (+ 2) which sum to give the coefficient of the k- term (- 3)
The factors are - 1 and - 2
Use these factors to split the k- term
1 - k - 2k + 2k² ( factor the first/second and third/fourth terms )
1(1 - k) - 2k(1 - k) ← factor out (1 - k) from each term
= (1 - k)(1 - 2k)
1 - 3k + 2k² = (1 - k)(1 - 2k) and
2k - 6k² + 4k³ = 2k(1 - k)(1 - 2k)
(b)
Given
2ax - 4ay + 3bx - 6by ( factor the first/second and third/fourth terms )
= 2a(x - 2y) + 3b(x - 2y) ← factor out (x - 2y) from each term
= (x - 2y)(2a + 3b)
Answer:
The correct answer is B.
Step-by-step explanation:
There is no clear rule regarding the relationship with these numbers. So it is not linear.
Good Luck!
