Step-by-step explanation:
radius of large sphere is R,
then volume is (4/3)*pie*R³
and
the radius of small sphere is r,
then volume is (4/3)*pie*r³
condition is,
volume of larger sphere is twice of the volume of smaller sphere.
then, (4/3)*pie*R³=2*(4/3)*pie*r³;
R³= 2r³
R=(2^⅓)*r
Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
Answer:
No, because 1.25% times 3 is 3.75% which is less than 6%
Step-by-step explanation:
Quarterly is every 3 months
6% interest is 1.06, 6 cents on the dollar
Monthly interest rate is 1.25% so 1.25 × 3 is 3.75
So, 1.25% times 3 is 3.75% which is 2.25% less than 6%
Hope this helps!
Have a great day!

Answer:
d=√(x2-x1)² + (y2-y1)²
Step-by-step explanation:
ans is √85 unit
Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
