What is equivalent to 3 radical 8
klemol [59]

Answer:

Equivalent 3\sqrt{8}=6\sqrt{2}

Step-by-step explanation:

Given: 3 radical 8

Mathematically 3 radical 8 can be written as 3\sqrt{8}

We have to find an equivalent to 3\sqrt{8}.

Given expression can be written as ,

3\sqrt{8}=3\sqrt{4 \times 2}

On further simplification, we get,

3\sqrt{4 \times 2}=3(\sqrt{4} \sqrt{2} )

We know \sqrt{4}=2

further simplification gives,

3\sqrt{8}=6\sqrt{2}

Thus, Equivalent 3\sqrt{8}=6\sqrt{2}

The perimeter of a rectangle is 42 cm and the area is 80 cm². Write an equation to model the situation and find the dimensions o
mafiozo [28]

Answer:

16cm by 5cm

Step-by-step explanation:

P=2(l+w)  

A= wl

80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

you then would have to find 2 numbers that would add up to make 42.

When you try 16*2+5*2= 32+10= 42 cm as your perimeter.

16*5= 80 cm^2 as your area.

The amount of radioactive element remaining, r, in a 100mg sample after d days is represented using the equation r=100(1/2) d/5.
Ludmilka [50]

Answer:

   12.94%

Step-by-step explanation:

r = 100(1/2)^(d/5) = 100((1/2)^(1/5))^d ≈ 100(.87055)^d

The daily decrease is 1 - 0.87055 = 0.12944 ≈ 12.94%

Find the y-coordinate of the y-intercept of the polynomial function defined below. f(x)=2(3x+4)(x^2+2)
Salsk061 [2.6K]

Answer:

Step-by-step explanation:

The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).

How was this obtained. notice that if x = 0 then

f(0) = 2(3*0+4)(0^2 + 2)

f(0) = 2(4)(2)

f(0) = 16 just as the graph tells us.
