Answer:
d = 2(40.11 cm) = 80.22 cm
Step-by-step explanation:
The formula for volume of a sphere is V = (4/3)πr³
and here V = (4/3)πr³ = 2145 cm³
Let's simplify this equation by multiplying both sides by (3/4); this will cause (4/3) to disappear:
(3/4)(4/3)πr³ = (3/4)2145 cm³, or
r³ = 1608.75 cm³
Taking the cube root of both sides, we get:
r = 40.11 cm
Remembering that diameter = 2 times radius, we calculate the diameter:
d = 2(40.11 cm) = 80.22 cm
Answer:
$74.25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
I = 600 × 0.055 × 2.25 = 74.25
I = $ 74.25
The simple interest accumulated
on a principal of $ 600.00
at a rate of 5.5% per year
for 2.25 years is $ 74.25.

Answer:
B
Step-by-step explanation:
a parabola would be x2 since it is square rooted it would be a curved so the answer would be the second graph
Range is the y-values and since the arrows extend off the graph, we can assume it goes on forever so
answer: (-infinity,+infinity)
make sure it’s parenthesis, not brackets
