Answer:
Option A
Explanation:
the ratio of radii to volume is ^3 "to the third power"
so 5^3 : 9^3 would be the ratio for volumes
125:729
(x^6 - 4x^5 - 7x^3)/2x^3=x^3(x^3-4x^2-7)/2x^3= (x^3-4x^2-7)/2
The answer is A- (3,5), (5,1), (7,-2), (9,-6)
104,229
Ten thousands place is the 0
9 = ones
2 = tens
2 = hundreds
4 = thousands
0 = ten thousands
1 = hundred thousands
You are asking for rounding to the ten thousands, if number before that is 5+, round up, if 4-, round down
100,000 is your answer
Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
