Who says V1=V2?
if we simplify we get
(2/3)pir₁³=12pir₂²
for V1 to equal V2
a.
solve for r₁ to find r₁ as a function of r₂
(2/3)pir₁³=12pir₂²
times 3/2 both sides and divide by pi
r₁³=18r₂²
cube root both sides
r₁=∛(18r₂²)
if solve for r₂
(2/3)pir₁³=12pir₂²
divide by 12pi both sides
(1/18)r₁³=r₂²
squer root both sides
√((1/18)r₁³)=r₂
double radius of pond which is r1
√((1/18)r₁³)=r₂
r₁ turns to 2r₁ to double radius
√((1/18)(2r₁)³)=r₂double
√(8(1/18)(r₁)³)=r₂double
(√8)(√((1/18)(r₁)³))=r₂double
√((1/18)r₁³)=r₂ so
(√8)(r₂)=r₂double
(2√2)(r₂)=r₂double
the radius of the tank is multipled by 2√2
Answer:
8X2-38X-380
Step-by-step explanation:
(2x+10)(4x-38)
Expand the brackets.
2X(4X-38)+10(4X-38)
Multiple the inner ones by the outer ones
(2X)(4X)-(38)(2X)+(10)(4X)-(10)(38)
=> 8X2-78X+40X-380
8X2-38X-380
209 kilograms is the answer. Hope you do well!
Answer:
so if alexia baked 42 cupcakes you add like this
6 strawberry+18 vanilla+9 chocolate= 33 then you take 33 and minus it from 42
42-33= 9 carrot cake cupcakes
hopes this helped you.
