How do I get the answer??

Answer:

4√10

Step-by-step explanation:

Hello!

Let's first simplify the radical.

We can do this by expanding the radical:

We need to pull out a perfect square factor to expand a radical and simplify it. In 45, we have 9 and 5 multiplied, and 9 is a perfect square.

Let's work with √45:

  • √45 can be written as √9 * √5 (using the rule √ab = √a * √b)
  • √9 simplifies to 3, so it is 3√5

Now we can simplify the operation in the parenthesis by combining like terms:

  • 3√5 + √5
  • √5 + √5 + √5 + √5
  • 4√5

Now using the same rule as above, we can multiply the values:

  • √2(4√5)
  • 4√10

Your solution is 4√10

The volume V of a cylinder is computed using the values 8.8m for the diameter and 5.8m for the height. Use the linear approximat
Delvig [45]

Answer:

The maximum error is approximately Ev=24%

Step-by-step explanation:

the volume of the cylinder V is

V= π/4*H*D²

where H= height and D= diameter

the variation of V will be

dV = (∂V/∂H)*dH + (∂V/∂D)*dD

dV = π/4*D²*dH  +π/2*H*D*dD

if we divide by the volume V

dV /V  = (π/4*D²*dH  +π/2*H*D*dD )/( π/4*H*D²) = dH/H + 2*dD/D

dV /V =  dH/H + 2*dD/D

then we can approximate

error in V= Ev= ΔV/V ≈ dV/V

error in H= Eh=ΔH/H ≈ dH/H

error in D= Ed=ΔD/D ≈ dD/D

thus

Ev= Eh + 2*Ed

since Ed=Eh=E=8%

Ev=  Eh + 2*Ed =3*E=3*8%=24%

Ev= 24%

therefore the maximum error is approximately Ev=24%

Select the function that's represented in the graph. Question 5 options: A) ƒ(x) = x2 – 3 B) ƒ(x) = –1∕2x2 – 3 C) ƒ(x) = –x2 – 3
Neporo4naja [7]

Answer:

a)

Step-by-step explanation:

hello,

because of the end behaviour the constant in  x^2 should be positive so we have a) or d)

f(0)=-3 in both cases

for A) f(x)=

x^2-3=(x-\sqrt{3})(x+\sqrt{3})

so f(x)=0 for x=\sqrt{3} \ or \  x = -\sqrt{3}

so the correct answer is A)

hope this helps
